    专利说明:

    [001] The present invention relates to electrical connectors and electrical connector assemblies, and, more specifically, to a connector with shear screws with an insertion plug.
    [002] Utility transmission lines may include electrical connectors and / or sets of electrical connectors positioned above or below the ground. For example, connectors with known shear bolts serve as underground junctions for copper cables ranging from 2/0 AWG to 75 kcml and for applications up to 35 kV. The shear bolt connectors include a housing for receiving conductors and make use of screws that are tightened to extend into the housing to physically contact the conductors and screw towards the conductors to secure them in the housing.
    [003] Untimely interruptions in the electrical transmission can occur when the conductors separate or dislodge from the housing. This can be time consuming and costly for any electrical utility.
    [004] Connectors with shear screws suffer from the disadvantage that the signals that travel through a screw are limited by the amount of contact between the conductor and the screw. The amount of contact is limited by the threaded end of the screw and the amount of deformability of the conductor. For example, the threaded end of the screw limits the amount of contact because it creates an irregular interface with the conductor (the conductor can be substantially cylindrical and the screw can have a flat or inconsistent threaded end). The amount of deformability of the conductor limits the amount of contact because it limits the ability of the screw to penetrate the conductor, thus limiting the amount of contact. In the case of conductors with little deformability, these limitations increase the risk of the conductors being disconnected from the electrical connector housing. In addition, when the screws directly deform the conductor, the filaments in the conductor can break, thereby reducing the ability to retain tension, especially when the screws are repeatedly loosened and tightened.
    [005] A prior art electrical connector (on which the preamble of claim 1 is based) is disclosed in patent US2033 / 0124915 A1. The connector includes a block with a series of conductor receiving passages. One or two channels of threaded fastening screws extend into the block and open each pass. The fixing screws on these channels require an adapter at each pass for fitting with a front end of a wire positioned in the channel. Different adapter sizes can be used to hold wire ends of different diameters. Each adapter is positioned in its associated passage being positioned at the main end of the associated wire which is then fed into the associated passage.
    [006] An electrical connector, a conductive insert and an electrical connector set that do not suffer from one or more of the above disadvantages would be desired in the art.
    [007] According to the invention, an electrical connector is provided comprising: a conductive housing; and a conductive insert positioned within the conductive housing; a screw positioned inside the conductive housing; wherein the conductive housing includes a configuration for receiving a conductor and making electrical communication with the conductor via insertion; and wherein the screw is positioned within the housing so as to urge the insertion against the conductor when the screw is adjusted, characterized in that the conductive housing includes an adhesive applied between the conductive housing and the conductive insert to hold the conductive insert in place during driver positioning.
    [008] The invention will be described below as an example with reference to the attached drawings, among which:
    [009] FIG. 1 illustrates a perspective view of an exemplary electrical connector assembly installed between two conductors in accordance with an embodiment of the present invention.

    [020] An electrical connector set, an electrical connector and a conductive insert are revealed. The embodiments of the present invention enable greater retention of electrical connectors compared to similar electrical connectors exempt from conductive insertion, provide greater conductivity between conductors compared to similar electrical connectors exempt from conductive insertion, offer versatility with conductors of varying dimensions, distribute strength on a conductor, thereby reducing or eliminating the breakage of the conductor's filaments and combinations thereof.
    [021] FIG. 1 illustrates an electrical connector assembly 100 that includes an electrical connector 102, a first conductor 104 and a second conductor 106. Electrical connector assembly 100 is suitable for any suitable application. For example, in a certain embodiment, the electrical connector assembly 100 is a connector for an electrical power distributor to be placed in suspension. In another embodiment, the electrical connector assembly 100 is a connector for an electrical power distributor to be positioned underground.
    [022] The electrical connector 102 electrically connects the first conductor 104 to the second conductor 106. The first conductor 104 and the second conductor 106 are conductors of electricity, such as twisted cables, capable of transmitting electrical energy and / or signals. In a certain embodiment, the first conductor 104 and the second conductor 106 are made of the same material, for example, copper or aluminum. In another embodiment, the first conductor 104 and the second conductor 106 are made of different materials, for example, the first conductor 104 is made of copper and the second conductor 106 is made of aluminum. In a certain embodiment, the first conductor 104 and the second conductor 106 are of the same size and / or shape. In another embodiment, the first conductor 104 and the second conductor 106 have different sizes and / or shapes, for example, the first conductor 104 has a greater or lesser thickness than that of the second conductor 106.
    [023] With reference to FIG. 2, the electrical connector 102 includes a conductive housing 108 and a conductive insert 110 positioned within the conductive housing 108 to receive and retain the first conductor 104 (see FIG. 1) and / or the second conductor 106 (see FIG. 1 ). Conductive housing 108 makes electrical communication with the first conductor 104 and the second conductor 106 through conductive insert 110.
    [024] Conductive housing 108 is made of any suitable material. In a certain embodiment, for example, as in an aerial application, conductive housing 108 is made of aluminum. In another embodiment, for example, as in an underground application, conductive housing 108 is made of copper.
    [025] Conductive housing 108 is of any geometry. As shown in FIG. 1, in a certain embodiment, the conductive housing 108 is in the form of a cone trunk. In another embodiment, as shown in FIG. 3, conductive housing 108 is a substantially flat part 302 of electrical connector 102 with conductive inserts 110 having a corresponding geometry. In yet another embodiment, the conductive housing 108 is cylindrical, rectangular, cubic, hexagonal or of any other suitable geometry, with the conductive insert 110 having a corresponding geometry.
    [026] With reference again to FIG. 1, conductive housing 108 includes an adhesive to secure conductive insert 110 in a predetermined position. Conductive housing 108 includes an adhesive (not shown) applied between conductive housing 108 and conductive insert 110 to hold conductive insert 110 in place when positioning the first conductor 104 (see FIG. 1) and / or the second conductor 106 (see FIG. 1). In a certain embodiment, the adhesive is a temporary adhesive that is only present during assembly and does not affect electrical conductivity during the operation of electrical connector set 100. In a certain embodiment, conductive housing 108 includes suitable alignment or fixing elements (not shown) for aligning and securing the conductive insert 110 within the conductive housing 108. Suitable alignment or fastening elements include, but are not limited to, threads, fittings, clamps, protrusions, keyings, recesses, fasteners, other suitable alignment elements or combinations of these.
    [027] In a certain embodiment, conductive housing 108 includes one or more screws 112 positioned within it. The one or more screws 112 extend from outside the conductive housing 108 and through it to contact the conductive insert 110 (see FIG. 2). The screws 112 are positioned so that, when tightened by rotation, they drive the conductive insert 110 against the first conductor 104 and / or the second conductor 106. When impelling the screws 112 towards the conductive insertion 110, it engages the first conductor 104 or the second conductor 106 and the electrical connection between the first conductor 104 or the second conductor 106 and the conductive housing 108 is formed or enlarged, thereby forming or increasing the electrical connection between the first conductor 104 and the second conductor 106.
    [028] As shown in FIG. 1, in a certain embodiment, four screws 112 are included. A first screw 112a and a second screw 112b are located in a first part 103 proximal to the first conductor 104 of the conductive housing 108. A third screw 112c and a fourth screw 112d are located in a second part 105 of the conductive housing 108 proximal to the second conductor 106. The first screw 112a and the second screw 112b correspond to a first conductive insert 110a (for example, see FIG. 2) positioned within the conductive housing 108 proximally to the first conductor 104. Similarly, the third screw 112c and the fourth screw 112d in the part of the conductive housing 108 proximal to the second conductor 106 correspond to a second conductive insert 110b (for example, see FIG. 2) positioned within the housing conductor 108 proximal to the second conductor 106. As will be seen, less than four screws 112 or more than four screws 112 can be used. Furthermore, the arrangement of the screws 112 can be in any suitable orientation.
    [029] Conductor housing 108 holds first conductor 104 and / or second conductor 106 within conductor housing 108 and / or conductive inserts 110. In a certain embodiment, conductor housing 108 is constructed and designed so that the first conductor 104 and the second conductor 106 are positioned in contact with each other (not shown) or close to each other within the conductive housing 108. With reference to FIG. 2, in another embodiment, the conductive housing 108 includes an inner wall 202 that separates a first conductive region 204 with the first conductor 104 from a second conductive region 206 with the second conductor 106. Each of the conductive regions first 204 and second 206 of the housing 108 includes an end part 212 and an inner part 214. The respective end parts 212 are configured to receive the first conductor 104 and the second conductor 106, and, during installation, the ends of the first conductor 104 and the second conductor 106 are positioned within the respective internal parts 214 so that they support and make contact with the internal wall 202.
    [030] Conductive insert 110 is configured to firmly retain the first conductor 104 (see FIG. 1) within the first conductive region 204 and / or the second conductor 106 (see FIG. 1) within the second conductive region 206 Retention of the first conductor 104 and / or the second conductor 106 is achieved by any suitable mechanisms or elements in the conductive insert 110 constructed and designed to make contact with the first conductor 104 and / or the second conductor 106. As illustrated in FIG . 2, in a certain embodiment, the conductive insert 110 includes engagement elements 208, such as spikes or ridges, to firmly engage the first conductor 104 and / or the second conductor 106. The engagement elements 208 are located on a surface of engagement 203 of the conductive insert 110. During installation, the first conductor 104 and the second conductor 106 are inserted into the conductive insert 110 adjacent to the engagement surface 203. In a certain embodiment, the engagement elements 208 engage in a deformed manner. to the first conductor 104 and / or the second conductor 106 by pressing the conductive insert 110 towards the first conductor 104 (see FIG. 1) and / or the second conductor 106 (see FIG. 1). In other embodiments, the first conductor 104 and / or the second conductor 106 are held by a rough surface (not shown) at the conductive insert 110, by axial grooves (not shown) at the conductive insert 110, by threads (not shown) on conductive insert 110, by independent protrusions (not shown) on conductive insert 110 or combinations thereof.
    [031] Coupling elements 208 are distributed in conductive insert 110 in any suitable manner. For example, with reference to FIG. 2, in a certain embodiment, the engaging elements 208 are distributed in a consistent periodic design, in which each of the engaging elements 208 extends in a substantially vertical orientation, that is, the orientation essentially perpendicular to the longitudinal axis of the conductive insert 110 .
    [032] With reference to FIG. 4, in another embodiment, the engaging elements 208 are distributed in a consistent periodic design and each of the engaging elements 208 extends at an angle 402, in relation to the longitudinal axis of the conductive insert 110, which is not vertical, by For example, towards the end end 212 (see FIG. 2) of a corresponding conductive housing 108 or the inner part 214 (see FIG. 2) of the corresponding conductive housing 108.
    [033] With reference to FIG. 5, in a certain embodiment, the engaging elements 208 are separated by substantially flat regions 302 between each of the engaging elements 208 on the engaging surface 203.
    [034] With reference to FIG. 6, in yet another embodiment, the engagement elements 208 are distributed in a non-periodic design and / or include engagement elements 208 of different heights, shapes, orientations or combinations thereof.
    [035] Conductive insert 110 includes any other elements capable of engaging the conductive housing 108 and / or retaining the first conductor 104 and / or the second conductor 106. For example, with reference to FIG. 6, in a certain embodiment, the conductive insert 110 includes an increasing thickness, which is composed of a first maximum thickness 602 in a first region 604 less than a second maximum thickness 606 in a second region 608, or which otherwise , is substantially tapered, partially tapered or inclined (regardless of the inclination formed by the engaging elements 208). The first region 604 corresponds to the terminal part 212 (see FIG. 2) of the conductive housing 108 or the internal part 214 (see FIG. 2) of the conductive housing 108, while the second region 608 corresponds to the respective counterpart of the terminal 212 (see FIG. 2) of conductive housing 108 or inner part 214 (see FIG. 2) of conductive housing 108. In contrast, as shown in FIG. 2, in a certain embodiment, the conductive insert 110 includes a substantially consistent thickness throughout its length.
    [036] With reference to FIG. 7, in a certain embodiment, an external support surface 703 of the conductive insert 110 is constructed and designed to adapt to and make contact with the shape of the conductive housing 108. In a certain embodiment, the conductive insert 110 is constructed and designed to be positioned in a single predetermined orientation within the conductive housing 108 (see FIG. 2). In a certain embodiment, insert 110 includes alignment elements to assume a predetermined orientation within conductive housing 108. For example, in one embodiment, conductive insert 110 includes threads, inserts, clamps, protrusions, keyings, recesses, fasteners or any elements alignment lines corresponding to conductive housing 108 or combinations thereof.
    [037] In addition, or alternatively, in a certain embodiment, the conductive insert 110 includes a screw recess 702 capable of providing alignment and distributing force from one of the screws 112 (see FIG. 2) along the entire conductive insert 110. After tightening screw 112 towards the first conductive region 204 (see FIG. 2) and / or the second conductive region 206, the screw 112 engages with the screw recess 702. The geometry of the screw recess 702 corresponds to the geometry of screw 112. In a certain embodiment, screw recess 702 includes a base 704, configured to receive and engage with the base of screw 112. In a certain embodiment, screw recess 702 includes threads (not shown) . As shown in FIG. 8, in a certain embodiment, the screw recess 702 is a cylindrical recess with a slightly wider diameter than the screws 112. In this embodiment, when tightening the screw 112, it engages and exerts force on the base 704 of the screw recess 702 .
    [038] With reference to FIG. 8, in a certain embodiment, the conductive insert 110 includes two screw recesses 702 and a substantially curved geometry.
    [039] With reference to FIG. 9, in a certain embodiment, the conductive insert 110 includes a substantially cylindrical geometry with one or more engagement regions 809, including engagement elements 208, and a non-engagement region 804 free of engagement elements 208.
    [040] With reference to FIG. 10, in a certain embodiment, the conductive insert 110 includes engagement elements 208 which extend over the entire engagement surface 203 to receive the first conductor 104 and / or the second conductor 106 (see FIG. 1).
