    [0001] This invention relates to a method of manufacturing a cable with a resin molding. Conventionally, there is known a rotation sensor which consists of a magnetic sensor element, and a cable for carrying an output signal of the sensor element to the outside, wherein The sensor element and one end of the cable are formed (see JP-A-2010-48689). The rotation sensor described in JP-A-2010-48689 comprises a substrate with the sensor element mounted on it and a first end of the cable attached thereto, and the sensor element and the substrate with the first end of the cable are covered by a molded part. The molded portion is formed using dies having upper and lower dies, and molding a molding material comprising an elastomeric or rubber thermoplastic material. The upper and lower dies are formed with grooves having a diameter smaller than an outer diameter of the cable in their respective parts being respectively opposite, and the cable is held in the grooves. This prevents the cable from slipping from there due to pressure inside the dies during molding of the molded part. An improvement of the reliability of waterproofness is therefore ensured. See, for example, JP-A-2010-48689. In the rotation sensor configured as described above, when the outer surface of the cable sheath (cable liner) and the surface Inside the molded part are not in intimate contact with each other around the entire circumference of the sheath, there is a possibility of moisture entry through a small gap between the sheath and the molded part. Once the moisture entering through the space reaches the sensor element, this may adversely affect the detection accuracy of the sensor element. Therefore, it is an object of the present invention to provide a method of manufacturing a cable with a resin molding, which is capable of improving a watertightness against the entry of moisture through a gap between a cable sheath and a molded resin product. According to one embodiment of the invention, a method of manufacturing a cable with a resin molding comprising a cable section comprising an electrical wire and a sheath comprising a synthetic resin covering the electrical wire, and a resin molding section in which a portion of the sheath is molded by a resin, comprises: receiving a portion of the cable section in a receiving space in a matrix formed with a molten resin inlet, a passage inlet flow, and a resin reservoir inside; injecting a molten resin from the inlet into the receiving space, a portion of the injected molten resin flowing through the inlet flow passage and being retained in the resin reservoir, the portion of the sheath being melted by the heat of the molten resin; Solidifying the molten resin to thereby form a molded resin product; and removing its solidified useless portion in the resin tank from the molded resin product.
    [0002] In the embodiment, the following modifications and changes can be made. (i) The inlet flow passage is open in the receiving space at a location such that the portion of the sheath is between the inlet flow passage and the inlet. (ii) The inlet flow passage includes a progressive narrowing portion, which tapers gradually in a flow passage area from a resin reservoir side to a receiving space side opening. (iii) The molded resin product after removal of the useless portion comprises a circular cylindrical portion with the cable section disposed at the center thereof, and the circular cylindrical portion is not more than 15 mm in diameter. outside diameter. (iv) The method further comprises connecting to the wire a sensor for measuring a physical quantity, and forming the sensor with the portion of the sheath. [0009] [Points of the invention] The method of manufacturing the cable with the resin molding according to the invention makes it possible to improve the watertightness against the entry of moisture by a space between the sheath. cable and the molded resin product.

[Embodiment] Fig. 1 is a perspective view showing an appearance of a cable 1 with a resin molding produced with a manufacturing method in the embodiment of the present invention. Figure 2A is a top view showing the cable 1 with the resin molding. Figure 2B is a side view showing the cable 1 with the resin molding. The cable 1 with the resin molding comprises a resin molding section 2 comprising a molded resin, a cable section 3 having an end molded by the resin molding section 2, and a sensor 4 connected to the section. In Figures 2A and 2B, the cable section 3 and the sensor 4 within the resin molding section 2 are indicated by a dashed line. The resin molding section 2 comprises a circular cylindrical portion 20, a boss 21, protruding from an end face 20a of the circular cylindrical portion 20 in an axial direction of the circular cylindrical portion 20, a portion conical 22, which is formed at the end opposite the boss 21, and an annular extension portion 23, which extends along the cable section 3 at one end of the conical portion 22. The circular cylindrical portion 20 is not more than 15 mm outside diameter, and the cable section 3 is disposed at the center of the circular cylindrical portion 20. The boss 21 is formed in a polygonal shape (in the example shown in FIG. rectangular) seen in the axial direction. The cable section 3 comprises first and second electric son 31 and 32, and a sheath 30 comprising a synthetic resin, and the first and second electric son 31 and 32 together are covered by the sheath 30. Part of the Sheath 30 is molded by the resin of the resin molding section 2. The first electrical wire 31 comprises a central conductor 311 having a highly conductive metal such as copper, and an electrically insulating coating 312, which covers the central conductor 311. The second electrical wire 32 similarly comprises a central conductor 321 comprising a highly conductive metal such as copper, and an electrically insulating coating 322, which covers the central conductor 321. The first and second electrical wires 31 and 32 are exposed from one end of the sheath 30 molded by the resin molding section 2. Similarly, the electrically insulating coatings 312 and 322 are removed at the end of the first and second electrical wires 31 and 32, so that the center conductors 311 and 321 are exposed in the portions of which the electrically insulating coatings 312 and 322 have been removed. The sensor 4 is designed to measure a physical quantity, such as the strength of a magnetic field and the like, and comprises a body 40 comprising a detection portion for the physical quantity, and first and second connection wires 41 and 42, which are taken out of the body 40. The body 40 is configured in such a way that its detection part comprising a Hall effect element for example is sealed with a sealant such as resin, ceramic or equivalent and all of it, with the portion of the sheath 30, is molded by the resin molding section 2. The first connecting wire 41 is electrically connected by welding to the center conductor 311 of the first wire 31, while the second connecting wire 42 in a similar manner is electrically connected to the center conductor 321 of the second electrical wire 32. [0017] The cable 1 with the resin molding is used, for example, in a measuring apparatus for detecting a rotational speed of an object to be measured from a change of force of the magnetic field, and the resin molding section 2 is received in a receiving hole formed in this measuring apparatus. The boss 21 of the resin molding section 2 acts as an anti-rotating part to suppress the rotation of the resin molding section 2 within this receiving hole. [0018] [Method of manufacturing the cable with the resin molding] Figure 3 is a perspective view showing dies 50 used to manufacture the cable 1 with the resin molding. The dies 50 consist of an upper die 51 and a lower die 52. The resin molding section 2 is formed by combining the upper die 51 and the lower die 52 together and injecting a molten resin into a resulting gap of these. The upper die 51 is formed with an upper cavity 510, an upper resin reservoir 511, an upper inlet flow passage 512, an upper injection passage 513, and an upper wire holding portion 514 The lower die 52 is formed with a lower cavity 520, a lower resin reservoir 521, a lower inlet flow passage 522, a lower injection passage 523, and a lower wire holding portion 524. upper die 51 and the lower die 52 are combined by moving the upper die 51 and the lower die 52 relative to each other so as to bring a corresponding surface 51a of the upper die 51 and a corresponding surface 52a of the lower die 52 in contact with each other. The upper cavity 510, the upper resin reservoir 511, the upper inlet flow passage 512, the upper injection passage 513 and the upper cable holding portion 514 are formed as recessed portions relative to each other. at the corresponding surface 51a of the upper die 51.

[0022] A molten resin is injected from the injection passage 503. in the cavity 500 of the dies 50. The resin reservoir 501 retains a portion of the molten resin flowing through the injection passage 503 into the cavity 500. The cavity 500 and the resin reservoir 501 are in communication with each other. with each other through the inlet flow passage 502 between. That is, the portion of the molten resin flowing in the cavity 500 flows through the inlet flow passage 502 into the resin reservoir 501. [0023] FIG. an enlarged view showing the upper inlet flow passage 512. Fig. 4E is an enlarged view showing the lower inlet flow passage 522. Fig. 4C is an enlarged view showing a first opening 502c of the flow passage 50 is a view from inside the cavity 500.

FIG. an enlarged view showing an inlet 503a of the injection passage 503 seen from the inside of the cavity 500. As shown in FIG. 4A, the upper inlet flow passage 512 comprises a portion of diameter enlarged 512a, which is progressively widening t in the flow passage region from the side of the upper cavity 510 to the side of the upper resin reservoir 511, and a circular divided cylindrical portion 512b, which is formed on the side of the upper resin reservoir 511 by relative to the enlarged diameter portion 512a, and whose flow passage section is the same as the maximum flow section of the enlarged diameter portion 512a. A circumferential edge 512c opening on the side of the upper cavity 510 of the enlarged diameter portion 512a, and a circumferential edge 512d opening on the side of the upper resin reservoir 511 of the circular cylindrical portion divided into two 512b are each semi -Circulars. [0025] The lower inlet flow passage 522 is formed in a manner similar to the upper inlet flow passage 512. That is, as shown in FIG. lower inlet flow passage 522 includes an enlarged diameter portion 522a, which progressively widens in the flow passage area from the side of the lower cavity 520 to the side of the lower resin reservoir 521, and a a split cylindrical circular portion 522b, which is formed on the side of the lower resin reservoir 521 with respect to the enlarged diameter portion 522a, and whose flow passage section is the same as the maximum flow section of the enlarged diameter portion 522a. A circumferential edge 522c opening on the side of the lower cavity 520 of the enlarged diameter portion 522a, and a circumferential edge 522d opening on the side of the lower resin reservoir 521 of the circular cylindrical portion divided into two 522b are each semi -Circulars. The inlet flow passage 502 has a conical portion 502a having the enlarged diameter portions 512a and 522a of the upper die 51 and the lower die 52, and a circular cylindrical portion 502b having the circular cylindrical portions divided into two respective ones 512b and 522b of the upper die 51 and the lower die 52. The conical portion 502a has a conical inner surface, and is progressively reduced in inner diameter from the circular cylindrical portion 502b to the side of the cavity 500. other words, the inlet flow passage 502 includes the conical portion 502a as a progressive narrowing portion whose flow passage section tapers progressively from the resin reservoir side 501 to the first opening 502c on the cavity 500. As shown in FIG. 4C, the first opening 502c on the side of the cavity 500 of the inlet flow passage 502 has a circular circumferential edge having the circumferential edge 512c opening the upper inlet flow passage 512 of the upper die 51, and the circumferential edge 522c opening the passage lower inlet flow 522 of the lower die 52. Also, as shown in Fig. 4D, the second opening 502d on the side of the resin tank 501 of the inlet flow passage 502 has an edge circumferential ring having the circumferential edge 512d of opening of the upper inlet flow passage 512 of the upper die 51, and the circumferential edge 522c of opening of the lower inlet flow passage 522 of the lower die 52. The inlet 503a of the injection passage 503 is formed at one end on the side of the cavity 500 of the upper injection passage 513 and the lower injection passage. r 523, and has a circular circumferential edge having a circumferential edge 513a opening the upper injection passage 513 of the upper die 51 and a circumferential edge 523a opening the lower injection passage 523 of the lower die 52. A method of manufacturing the cable 1 with the resin molding implemented using the dies 50 comprises the steps of: receiving a portion of the cable section 3 in the cavity 500 of the dies 50; injecting a molten resin from the injection passage 503 into the cavity 500; solidifying the molten resin to thereby form a molded resin product; and removing its unnecessary portion of the molded resin product. These steps will each be described in detail below. Figure 5 is an explanatory view showing the lower die 52 with the cable section 3 and the sensor 4 disposed thereon. As shown in Fig. 5, one end of the cable section 3 and the sensor 4 are disposed on the lower die 52. The upper die 51 is moved to the lower die 52, with the result that the cavity 500 is configured as a receiving space in the dies 50, with the end of the cable section 3 and the sensor 4 received therein. The cable section 3 is clamped between the upper cable holding portion 514 and the lower cable support 524. [Injection step] Figs. 6A-6F are schematic views showing a continuous flow of the molten resin 6 in the injection step. The molten resin 6 is a heat-melt resin to form the resin molding section 2, and is a fluid having fluidity capable of flowing through the injection passage 503 and the inlet flow passage 502. [0032] In the injection step, the molten resin 6 is injected from the inlet 503a into the cavity 500. A portion of the molten resin 6 injected into the cavity 500 flows through the passage of inlet flow 502 in the resin tank 501. A portion of the sheath 30 of the cable section 3 is then melted by the heat of the molten resin 6 flowing in the resin tank 501. [0033] The passage the inlet flow 502 is opened in the cavity 500 in a location such that the portion of the sheath 30 is between the inlet flow passage 502 and the inlet 503a. More specifically, the portion of the sheath 30 is included in a space defined by a straight line connecting the circumferential edge of the first opening 502c of the inlet flow passage 502 and the circumferential edge of the inlet 503e of the passageway. In the same way, the inlet 503e of the injection passage 503 is directed at the sheath 30. In other words, the sheath 30 is disposed on the line of extension of the central axis of the passage of injection 503 in the vicinity of the inlet 503a. As shown in FIG. 6A, the molten resin 6 delivered into the injection passage 503 is injected from the inlet 503e to the sheath 30. As shown in FIGS. 6B and 6C, the molten resin 6 flows on an outer surface (outer peripheral surface) 30e of the sheath 30. At this stage, the heat is conducted from the molten resin 6 to the sheath 30, which increases the temperature of the outer surface 30a of the sheath 30. When the additional molten resin 6 is injected into the cavity 500, as shown in FIG. 6D, the portion of the molten resin 6 flowing on the outer surface 30a of the sheath 30 is flows through the inlet flow passage 502 into the resin reservoir 501. The flow of the portion of the molten resin 6 into the resin reservoir 501 allows the larger amount of the molten resin 6 flowing over the outer surface 3 0e of the sheath 30, compared to when no resin reservoir 501 is formed in the dies 50. In other words, the time during which the molten resin 6 flows on the outer surface 30a of the sheath 30 is longer. Likewise, as shown in FIG. 6E, the increase of the molten resin 6 injected into the cavity 500 results in the increase of the amount of the inlet flow of the molten resin 6 in the Resin tank 501, and when the injection step is complete, as shown in Fig. 6F, cavity 500 and resin tank 501 are filled with resin. It should be noted that the air present between the upper die 51 and the lower die 52 in the cavity 500 and the resin tank 501 and equivalent before the injection step is discharged by a small gap between the corresponding surface 51a of the the upper die 51 and the corresponding surface 52a of the lower die 52 towards the outside of the dies 50 at the same time as the injection of the molten resin 6. The sheath 30 is heated by the molten resin 6 flowing on the outer surface 30a of the sheath 30, and a portion of the surface layer adjacent to the outer surface 30a is melted. This allows the sheath 30 to be welded in one piece with the resin when the molten resin 6 solidifies to form the solid resin. Therefore, sufficient watertightness is ensured. That is, even if moisture enters through a gap between the extension portion 23 (shown in FIG. 1) of the resin molding portion 2 and the sheath 30, the entry of moisture through the welded portion between the sheath 30 and the resin molding portion 2 in the end side (sensor side 4) of the cable section 3 is prevented. The molten resin 6 poured into the cavity 500 and the resin reservoir 501 is then solidified to thereby form a molded resin product, followed by the separation of the upper die 51 from the lower die 52, and the output of the molded resin product with cable section 3 of the equipment 50. [Removal step] In the removal step, the solidified part in the resin tank 501 and the inlet flow passage 502 is removed from the molded resin product.
    [0003] That is, the solidified resin portion in the resin reservoir 501 and the inlet flow passage 502 is unnecessary, and is therefore removed. It should be noted that burrs, if any, on the molded resin product taken out of the dies 50 are also removed. This results in the cable 1 with the resin molding as shown in Fig. 1. In this removal step, the molded resin product portion formed in the vicinity of the first aperture 502c in the transition passage. the inlet flow 502 is cut off. The inlet flow passage 502 has a conical shape towards the end of the first opening side 502c of the conical portion 502a, thereby allowing easy cutting of the molded resin product. On the other hand, the molded resin product can be cut using a cutting tool such as a cutter, or can be cut manually and by twisting. [Operation and advantageous effects of the embodiment] The embodiment described above has the following advantageous operation and effects. (1) Since, in the injection step, the sheath 30 is melted by the heat of the molten resin 6, and formed integrally with the resin molding section 2, the sealing at the water of the cable 1 with the resin molding is improved. (2) Since the inlet flow passage 502 has the first opening 502c in a location such that the sheath 30 is between the inlet flow passage 502 and the inlet 503a, the molten resin 6 injected from the inlet 503a flows on the outer surface 30e of the sheath 30 and flows easily into the inlet flow passage 502. This allows the sheath 30 to be melted safely by the heat of the molten resin 6. The watertightness is therefore further improved. (3) Since the inlet flow passage 502 includes the conical portion 502a whose flow passage section for the molten resin 6 progressively narrows from the side of the resin reservoir 501 to the first opening 502c, it is possible to easily remove the solidified molded resin product portion in the resin reservoir 501 and the inner inlet flow passage 502 in the removal step. Similarly, it is possible to reduce the mark on the outer circumferential surface of the circular cylindrical portion 20 (the cut surface of the resin molding product) of the resin molding section 2, therefore to have a good appearance, and, for example, upon receiving the resin molding section 2 into a receiving hole formed in a measuring apparatus, to prevent this cut portion from being jammed. (4) Since the dies 50 have the resin reservoir 501, it is possible to ensure that the quantity of the molten resin 6 flowing on the outer surface 30a of the sheath 30 melts the sheath 30, even if the outer diameter of the circular cylindrical portion 20 of the resin molding section 2 is small, and the volume of the resin molding section 2 is small. This makes it possible to reduce the outer diameter of the circular cylindrical portion 20 to not more than 15 mm, for example, thus making it possible to reduce the size of the cable 1 with the resin molding. (5) Since the sensor 4 is connected to the first and second electrical son 31 and 32 of the cable section 3, and is molded with the portion of the sheath 30, it is possible to prevent the entry of humidity in the body 40 of the sensor 4 or the respective connected parts of the first and second connection son 41 and 42 and the first and second electric son 31 and 32, thus allowing to increase the environmental resistance of the cable 1 with resin molding. [0047] [Summary of the Embodiment] The technical concept that is validated from the above-described embodiment will be described using the references and equivalent in the embodiment.
