Figure 2 schematically shows a side view of a hand-operated crimping tool 2 having a closed tool head 4 according to a second embodiment of the invention, shown in a non-crimping position.
The embodiment shown in Figure 2 differs from the embodiment shown in Figure 1 in that the tool head 4 is closed and in that the main part 11 is slidably connected to the body 6 by using pins 18, 20 arranged to slide in a groove 23. extending axially A along the tool 2. The groove 23 may be arranged in the body 6 or in the main part 11, and the pins may be arranged in the main part 11 or in the body 6.
Figure 3 schematically shows a side view of a hand-operated crimping tool 2 having a tool head comprising a pivotable main part 15 according to a third embodiment of the invention, shown in a non-crimping position.
The embodiment shown in Figure 3 differs from the embodiment shown in Figure 1 in that the tool head 4 comprises one (as will be discussed in more detail below) and in that the proximal pin 20 shown in Figure 1 and the pin 35 arranged at the proximal end of the main part 11 shown in figure 1 is replaced by only one pin 21 in the embodiment according to figure 4, and in that the body 6 and the proximal groove 24 extending axially A along the tool 2 in the embodiment according to figure 3 are arranged to extend correspondingly longer so as shown in Figure 3.
Thus, according to the embodiment shown in Figure 3, the main part 11 is arranged to extend along the body 6 and is slidably connected to the body 6 by using pins 18, 21 arranged to slide in respective grooves 22, 24 extending axially A along the tool 2. , where preferably two pins 18, 21 are used to control the movement of the main part 11 relative to the body. The grooves 22, 24 may be arranged in the body 6 or in the main part 11, and the pins may be arranged in the main part 11 or in the body 6. The handles 8, 10 are pivotally connected to the body 6 at pivot points 26, 28. The handles 8, 10 are further coupled to the main part 11 by respective levers 30, 32 which levers 30, 32 are pivotally connected to the main part 11 and a respective handle 8, 10 at pivot points 34, 36; 38, 40, preferably using pins 21; 39, 41. Crimping jaws 42, 44 are further, preferably removable, arranged at the body 6 and the tool head 4, in this embodiment at the main part 11, where the distal crimping jaw 44 is arranged at the tool head 4 and a proximal crimping jaw 42 is arranged at the body 6, between which crimp jaws 42, 44 at least one workpiece 43 is arranged to crimp when the crimp jaws 76, 44 12 are moved in the direction of each other.
Figure 4 schematically shows a view of a hand-driven crimping tool 2 having a tool head comprising a pivotable main part 15 according to a fourth embodiment of the invention, shown in a non-crimping position.
The embodiment shown in Figure 4 differs from the embodiment shown in Figure 1 in that the Tool Head 4 comprises a pivotable main part 15 (as will be discussed in more detail below) and in that only one handle 8 is pivotally connected to the body 6 at a pivot point 26. while the second handle 10 is fixed to the body 6. As shown in the figure, the body 6 preferably comprises two body parts 14, 16 between which the main part 11 is arranged to slide.
As can be seen in Figure 4 (and which also applies to all the other embodiments described herein), e.g. the handles 8, 10, the main part 11, or the pivotable main part 15 comprise a number of preferably disc-like lower parts. For example, a handle 8 may comprise two lower parts 8 ', 8 ", and the proximal part of the main part 11 may comprise at least two lower parts 11', 11" between which at least one lever 30, 32 may be arranged .
Figure 5 schematically shows a view of a hand-operated crimping tool 2 having a tool head comprising a pivotable main part 15 according to a fifth embodiment of the invention, shown in a non-crimping position.
The embodiment shown in Figure 5 differs from the embodiment shown in Figure 1 in that the Tool Head 4 comprises a pivotable main part 15 (as will be discussed in more detail below).
The tool head 4 according to this embodiment comprises a main part 11 and a pivotable hook-like main part 15 connected thereto at a pivot point 13, the main part 11 being arranged to extend along the body 6 and is slidably connected to the body 6 by using pins 18, 20 arranged to slide in respective grooves 22, 24 extending axially A along the tool 2, where preferably at least two pins 18, 20 are used to control the movement of the main part 11 relative to the body. The grooves 22, 24 may be arranged in the body 6 or in the main part 11, and the pins may be arranged in the main part 11 or in the body 6. The handles 8, 10 are pivotally connected to the body 6 at pivot points 26, 28. The handles 8, 10 are further coupled to the main part 11 by respective levers 30, 32 which levers 30, 32 are pivotally connected to the main part 11 and a respective handle 8, 10 at pivot points 34, 36; 38, 40, preferably using pins 35; 39, 41. Crimping jaws 42, 44 are further preferably removably arranged at the body 6 and the tool head 4, respectively, in this embodiment at the main part 11, where a distal crimping jaw 44 is arranged at the tool head 4 and a proximal crimping jaw 42 is arranged at the body 6, between which crimp jaws 42, 44 at least one workpiece (not shown in this figure) is arranged to crimp when the crimp jaws 42, 44 are moved in the direction of each other.
The body part 11 may comprise more than one part, Lex. at least one distal portion 46 and at least one proximal portion 48. The crimp jaw 44 may be provided at the distal end 50 of the distal portion 46 and the levers 30, 32 may be pivotally connected to the proximal end 52 of the proximal portion 48. The distal end 54 of the proximal portion 48 may be connected to the proximal end 56 of the distal portion 46. The pivotable main portion 15 may further be pivotally connected to the distal end 54 of the proximal portion 48 at a pivot point 13. The distal portion 46 may be substantially U-shaped and the proximal portion 48 may be substantially Y-shaped.
Said replaceable crimping jaws 42, 44 may further preferably be removably attached to the body 6 and the main part 11, through respective fastening elements 58, 60 such as screws.
To achieve that the pivotable head portion 15 of the tool head 4 ﬂ is automatically moved between an open head position and a closed head position depending on the relative position of the tool handles 8, 10 as will be discussed in more detail 76312 10 15 20 25 30 below , the pivotable part 15 is further arranged to be slidably guided along a curved path along the body 6 by using at least one pin 62 arranged to slide in a curved groove 64, where the curved groove defines the curved path. The curved groove 64 may be arranged in the body 6 or in the pivotable main part 15, and the at least one pin 62 may be arranged in the pivotable main part 15 or in the body 6.
According to this embodiment, the curved groove 64 is arranged in the body 6 and the at least one pin 62 is arranged in the pivotable main part 15, where further the curved groove 64 is arranged at its proximal end 66 to extend parallel to the above-mentioned grooves 22. 24 extending axially A along the tool 2, while the curved groove 64 is arranged in the direction of its distal end 68 to extend at an angle to and in the direction away from the above-mentioned grooves 22, 24. Thus, when the pin 62 arranged in the pivotable main part 15 moves along the curved groove 64 parallel to the above-mentioned grooves 22, 24, the pivotable main part 15 of the tool head 4 is kept in its closed position. When the pin 62 arranged in the pivotable main part 15 moves along the curved groove 64 at an angle to and in the direction away from the above-mentioned grooves 22, 24, the pivotable main part 15 of the tool head 4 leaves its closed position and is opened. When the pin 62 reaches its most distal position along the curved groove 64, the pivotable body portion 15 of the tool head 4 has reached its open position.
Figure 6 schematically shows a view of a hand-driven crimping tool 2 having a tool head comprising a pivotable main part 15 according to the fifth embodiment of the invention, shown in a crimping position.
As can be seen in Figure 6, when comparing Figure 5 with Figure 6, the pivotable body portion 15 of the tool head 4 disposed distally 1 of the hand-operated crimping tool 2 is automatically moved between an open head position (as shown in Figure 5) and a position with closed head (as shown in Figure 6) depending on the relative position of the tool handles 8, 10 arranged proximally 3 on the crimping tool 2, since the movement of the handles 8, 10 is coupled to the movement of the tool head 4, more specifically to the movement of the body part 11 and 76312 The pivotable main part 15 of the tool head 4. This is achieved by arranging the main part 11 axially slidable along the body 6, by arranging the pivotable main part 15 pivotable relative to the main part 11 and pivotably slidable along the body 6, by arranging the handles 8, 10 pivotable relative to the body 6, and by coupling the respective handles 8, 10 to the main part 11 via respective levers 30, 32 sv angularly arranged in relation to the main part 11 and in relation to the respective handles 8, 10 as has been discussed in connection with figure 5.
When the handles 8, 10 are compressed, the handles 8, 10 pivot about their respective pivot point 26, 28 arranged on the body 6, whereby the levers 30, 32 pivot about their respective distal pivot point 38, 40 arranged on the respective handle 8, 10, thereby their respective proximal pivot points 34, 36 where they are pivotally connected to the main part 11 of the tool head 4 proximally along the crimping tool 2, thus extending the distal end of the tool head 4 proximally along the crimping tool 2 towards the body 6. This results in the distal crimping jaw 44 being arranged at the tool head 4, in this embodiment the main part 11, ﬂ is moved by a lever mechanism in the direction of the proximal crimping jaw 42 arranged at the body 6, where the crimping jaws 42, 44 are thus arranged to be moved towards each other to crimp at least one workpiece (not shown in this embodiment) arranged in a crimping opening 70 arranged between the crimping jaws 42, 44. When separating ve tool handles 8, 10, the tool head 4 moves in the opposite direction, i.e. from the position shown in Figure 3 in the direction of the position shown in Figure 5.
When at least two pins 18, 20 are used to control the movement of the main part 11 relative to the body 6, the arrangement of the levers 30, 32 discussed above enables the pins 18, 20 to be arranged far apart, this increasing alignment of the main part 11 with the axis 2 of the tool 2 and decreasing the possible skew between the axis A of the tool 2 and the main part 11.
Figure 7 schematically shows a view of a hand-operated crimping tool having a tool head comprising a pivotable main part 15 according to a sixth embodiment of the invention, shown in a non-crimping position.
The embodiment shown in Figure 7 differs from the embodiment shown in Figure 5 in that in order to achieve that the pivotable main part 15 of the tool head 4 ﬂ is automatically moved between an open head position and a closed head position depending on the relative position of the tool handles 8, 10. , the free end 61 of the pivotable main part 15 is further arranged to be slidably guided along a curved path 63 relative to the body 6 by arranging a prestressed spring 65 arranged to push the free end 61 of the pivotable part 15 in the direction away from the main part 11, and by arranging a support means 67 in the body 6 along which the pivotable main part 15 is arranged to slide, where the design of the contact surfaces between the support means 67 and the pivotable main part 15 defines the curved path 63. The support means 67 can e.g. be a pin or a wheel.
The curved web 63 is arranged at its proximal end 69 to extend parallel to the above-mentioned grooves 22, 24 extending axially A along the tool 2, while the curved web 63 is arranged in the direction of its distal end 71 to extend in an angle to and in the direction away from the above-mentioned grooves 22, 24. Thus, when the free end 61 of the pivotable main part 15 moves along the curved path 63 parallel to the above-mentioned grooves 22, 24, the pivotable main part 15 is kept of the tool head 4 in its closed position. When the free end 61 of the pivotable main part 15 moves along the curved path 63 at an angle to and in the direction away from the above-mentioned grooves 22, 24, the pivotable main part 15 of the tool head 4 leaves its closed position and is opened. When the free end 61 of the pivotable main part 15 reaches its most distal position along the curved path 63, the pivotable main part 15 of the tool head 4 has reached its open position.
Figure 8 schematically shows a view of a hand-driven crimping tool 2 having a tool head 4 comprising a pivotable main part 15 according to a seventh embodiment of the invention, shown in a non-crimping position.
The embodiment shown in Fig. 8 differs from the embodiment shown in Fig. 5 in that in order to achieve that the pivotable main part 15 of the tool head 4 ﬂ is automatically moved between an open head position and a closed head position depending on the relative to the position of the tool handles 8, 10, a cam surface 72 at the end 74 of the pivotable main part 15 connected to the body 6 is arranged to be slidably guided along a cam surface 76 at the end 75 connected to the body 6 of a handle pivotally arranged at the body 6. 8. Said cam surface 72 of the pivotable main part 15 is arranged to pivot in the opposite direction of the distal free end 61 of the pivotable main part 15, and said cam surface 76 of the handle 8 is arranged to pivot in the opposite direction of the proximal free end 78 of the handle 8. A prestressed spring 65 is arranged to push the free end 61 of the pivotable main part 15 in the direction of the main part 11, thereby thus, when the handles 8, 10 ﬂ are spaced apart, the cam surface 76 presses on the handle against the pivotable body 15 thereby opening the tool head against the force of the spring 65, and when the handles 8 , 10 ﬂ is moved in the direction of each other, the pivotable main part 15 is no longer blocked by the cam surface 76 on the handle 8 and can move in the direction of the main part 11 thus closing the tool head.
The free end 61 of the pivotable main part 15 is thus arranged to be slidably guided along a curved path 63 in relation to the body 6, where the design of the cam surfaces defines the curved path 63.
Figure 9 schematically shows a side view of a hand-operated crimping tool 2 having a closed tool head 4 according to an eighth embodiment of the invention, shown in a non-crimping position.
As can be seen in Figure 9 (and which also applies to all the other embodiments described herein), at least one return spring 78, 80, in this embodiment two return springs 78, 80, are arranged to move the tool handles 8, 10 apart when the force which pushes the tool handles 8, 10 in the direction of each other are released, thus ﬂ facing the distal end 50 of the tool head 4 in the direction away from the body 6. 76312 10 15 20 25 30 13 The embodiment shown in figure 9 differs from the embodiment shown in figure 1 in that the tool head 4 is closed, and in that the movement of the handles 8, 10 arranged pivotally relative to the body 6 is arranged coupled to the movement of the main part 11 by a mechanism 31, which here is a cam mechanism, whereby the tool head 4 is arranged movably between a distal non-distal part. crimping position and a proximal crimping position depending on the relative position of the tool handles 8, 10 and is thus automatically movable between an open head position and a closed head position depending on the relative position of the tool handles 8, 10.
The body 6 is arranged between the distal end 1 and the proximal end 3 of the crimping tool 2. The tool head 4 is arranged distally 1 on the crimping tool 2, and the two handles 8, 10 are arranged proximally 3 on the crimping tool 2. The tool head 4 comprises a main part 11 arranged to extend along the body 6. The body 6 preferably comprises two body parts 14, 16 between which the main part 11 is arranged to slide. For the sake of clarity, the parts of the main part 11 which are obscured by the body part 14 are shown in broken lines in the figure. The main part is slidably connected to the body 6 by using pins 18, 20 arranged to slide in respective grooves 22, 24 extending axially A along the tool 2, where preferably at least two pins 18, 20 are used to control the movement of the main part 11 relative to the body. The grooves 22, 24 may be arranged in the body 6 or in the main part 11, and the pins may be arranged in the main part 11 or in the body 6. The handles 8, 10 are pivotally connected to the body 6 at pivot points 26, 28.
The main part 11 is arranged axially A slidable along the body 6. Crimping jaws 42, 44 are further preferably removably arranged at the body 6 and the main part 11, between which crimping jaws 42, 44 at least one workpiece (not shown in this figure) is arranged to crimp when the crimping jaws 42 , 44 ﬂ are extended in the direction of each other. For the sake of clarity, the parts of the crimp jaws 42, 44 which are obscured e.g. of a body part 14 or the main part 11 shown in broken lines in the figure. The handles 8, 10 are further connected to the main part 11 by a mechanism 31 which is a cam mechanism comprising at least one cam 82, 84, in this embodiment two cams 82, 84, which cams are connected to a respective handle 8, 10, and which cams are arranged to come into engagement with a cam follower means 86 arranged at the main part 11, such as e.g. a pin arranged on the main part 11.
When the handles 8, 10 are compressed, the handles 8, 10 pivot about their respective pivot point 26, 28 arranged on the body 6, whereby the respective cams 82, 84 ﬂ are moved in the direction of the cam follower means 86. When the respective cams 82, 84 engage with cam follower 86, the cam follower 86 disposed on the body portion 11 together with the body portion 11 is proximal along the crimping tool 2, thus ﬂ extending the distal end 50 of the tool head 4 proximally along the crimping tool 2 toward the body 6. This results in the distal word 4 , in this embodiment at the main part 11, ﬂ is replaced by a cam mechanism in the direction of the proximal crimping jaw 42 arranged at the body 6, the crimping jaws 42, 44 thus being arranged to be moved towards each other to crimp at least one workpiece (not shown in this embodiment) arranged in a crimp opening 70 arranged between the crimp jaws 42, 44. When the main part 11 moves proximally along body 6, the return springs 78, 80 are clamped between the main part 11 and the body 6, e.g. arranged between a pin 20 arranged on the main part 11 and a respective pin 88, 90 arranged on the body 6, thereby increasing a return spring force which tries to surface the tool handles 8, 10. Thus, when the force pushing the tool handles 8, 10 in the direction of each other is released, the return spring force from the tensioned return springs 78, 80 is arranged to ﬂ disassemble the tool handles 8, 10 thus ﬂ extending the distal end 50 of the tool head 4 in the opposite direction in the direction away from the body 6.
As mentioned above, the main part 11 is slidably connected to the body 6 by using at least one pin arranged to slide in at least one groove, and the optional pivotable main part 15 is further arranged to be slidably guided along a curved path along the body 6 by using at least one pin arranged to slide in a curved groove. As mentioned above, the body 6 preferably comprises two body parts 14, 16 between which the main part 11 is arranged to slide.
The main part 11 is preferably slidably connected to both body parts 14, 16 of the body 6, e.g. by using at least one pin connected to both body parts 14, 16 and arranged to slide in at least one groove in the main part 11, or by using at least one pin connected to the main part 11 and arranged to slide in at least one groove arranged in each of body parts 14, 16.
The pivotable main part 15 is further preferably arranged to be slidably guided along a curved path along both body parts 14, 16 of the body 6, e.g. by using at least one pin connected to both body parts 14, 16 and arranged to slide in a curved groove in the pivotable main part 15, or by using at least one pin connected to the pivotable main part 15 and arranged to be slidably guided along a curved groove arranged in each of the body parts 14, 16. Another possible embodiment is to arrange the free end 61 of the pivotable main part 15 to be slidably guided along a curved path 63 relative to the body 6 by arranging a prestressed spring 65 arranged to pushing the free end 61 of the pivotable main part 15 in the direction away from the main part 11, and arranging a support member 67 in the body 6 along which the pivotable main part is arranged to slide, as mentioned above. A further possible embodiment is to arrange the free end 61 of the pivotable main part 15 to be slidably guided along a curved path 63 relative to the body 6 by arranging a prestressed spring 65 arranged to press the free end 61 of the pivotable main part 15 in towards the main part 11, and to arrange a cam surface 72 at the end 74 of the pivotable main part 15 connected to the body 6 to be slidably guided along a cam surface 76 at the end of the pivot 6 connected to the body 6 by a handle 8 pivotable relative to the body 6. , as mentioned above.
The mechanism 31 coupling the handles and the tool head is preferably a lever mechanism or a cam mechanism as discussed in the embodiments above, but may also be another mechanism which similarly couples the movement of the at least one pivotable handle and the movement of the tool head, such as e.g. a gear mechanism.
The features of the embodiments discussed above may be combined in ways other than those explicitly described in the embodiments above. The invention thus relates to a hand-driven crimping tool 2 comprising a body 6 arranged between a distal end 1 and a proximal end 3 of the crimping tool 2, a tool head 4 arranged distally 1 on the crimping tool 2, and handles 8, 10 arranged proximally 3 on the crimping tool 2, where at least a handle 8, 10 is arranged pivotally relative to the body 6, where the tool head 4 is arranged axially A slidably along the body 6, where a distal crimp jaw 44 is arranged at the tool head 4 and a proximal crimp jaw 42 is arranged at the body between which crimp jaws 42, 44 a workpiece 43 is to be crimped, and where the movement of the at least one pivotable handle 8, 10 arranged relative to the body 6 is arranged coupled to the movement of the tool head 4 by a mechanism 31, whereby the tool head 4 is arranged movably between a distal non-crimping position and a proximal crimping position depending on the relative position of the tool handles 8, 10.
Crimping tools utilizing the invention may, as described above, be provided with an open head or a closed head. In an open head tool, the head must be much stronger than in a closed head tool to withstand the same amount of maximum shrinkage force, due to the fact that an open head structure is less rigid than a closed head structure. and will give in more easily during shrinkage.
A crimping tool with a closed head will thus be lighter than a crimping tool with an open head designed for the same amount of maximum crimping force if the crimping tools are made of the same material, this resulting in less load on the user.
A crimping tool with an open head, on the other hand, has the advantage that it is possible to e.g. crimp the ends of two very long wires and then remove the crimping tool from the crimped wires without having to pull the crimped wires out through the head of a crimping tool having a closed head. Furthermore, if the "non-crimped" ends of the two crimped wires are not free, which Lex. is the case when these ends are already attached to e.g. a respective electrical junction box, it is impossible to remove the crimped wires after crimping from a tool with a closed head.
Crimping tools utilizing the invention may, as described above, also be provided with a pivotable main body thereby utilizing the above-mentioned advantages of both hand crimping tools having open heads and hand crimping tools having closed heads.
In the above-mentioned embodiments, the tool head is arranged slidably connected to the body by using at least one pin arranged to slide in at least one groove extending axially along the tool. It is also possible to arrange the tool head slidably connected to the body by using other control means such as e.g. guide elements arranged in the body between which the tool head is guided as it slides along SÉOIIIIIICII. 76312
