Description

Technical Field

[0001] The present invention relates to a positioning device for a wire connector. Background Art

[0002] A wire connector is a device for realizing electrical connection between several wires. It generally includes several wiring units, and each wiring unit has several electrical connection parts for cooperating with wires for connection. The electrical connection parts of the same wiring unit can be electrically connected through an electrical connection piece. When several wires are respectively connected to the several electrical connection parts of the wiring unit, the electrical connection piece enables these wires to be electrically connected to each other. In order to realize the parallel connection between different wiring units, a conductive part is usually inserted and arranged on the outer side of the housing of the wire connector. By contacting and electrically connecting the conductive part with the electrical connection pieces of each wiring unit, the wires connected to different wiring units can be electrically connected. A positioning device is usually also used in cooperation with the wire connector, and the positioning device can install and fix the wire connector on an installation plane or a guide rail.

[0003] However, currently on the market, wire connectors and positioning devices are usually sold and used in sets. Wire connectors of different sizes and specifications need to be matched with corresponding specifications of positioning devices and cannot be mixed and used, which undoubtedly increases the production and purchase costs. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a positioning device that can be spliced and combined for use, and has better adaptability to wire connectors of different specifications.

[0005] To achieve the above object, the present invention provides a positioning device for a wire connector, including a bearing member that can be spliced side by side with other bearing members. The bearing member includes a support surface at its top and joint surfaces on both sides along the splicing direction. The support surface cooperates with and supports the bottom of the wire connector, and a first connection part for connecting and fixing with the wire connector is arranged on the support surface. Convex parts extending laterally along the splicing direction and concave parts that cooperate with the convex parts for insertion are respectively arranged at corresponding positions on the joint surfaces on both sides of the bearing member, and a second connection part for connecting and fixing with the installation plane is arranged on the convex parts.

[0006] The beneficial effects of the present invention are as follows: When in use, the appropriate number of bearing members can be selected according to the specifications of the wire connector to be installed and spliced side by side. These bearing members are connected and fixed in cooperation with the wire connector through the first connecting portion provided on the supporting surface at the top thereof. At the same time, the relative positions between adjacent bearing members can be kept relatively stable, making it not easy for adjacent bearing members to separate. The supporting surface can be in contact and cooperate with the bottom of the wire connector for support. The protrusions on the joint surface of one side of the bearing member can be inserted into the recesses on the joint surface of the other side of the adjacent spliced bearing member, so that the joint surfaces between adjacent bearing members can be mutually attached and not easily interfere with each other. The second connecting portion on the protrusion of the bearing member at the farthest end along the side-by-side connection direction of the bearing members can be used for connecting and fixing in cooperation with the installation plane, so that the wire connector and the positioning device can be fixed on the installation plane together, facilitating installation. Since the bearing members of the positioning device of the wire connector of the present invention have the same shape and structure, it is convenient for production and processing, reduces the production cost, and can also reduce the purchase cost of users.

[0007] Further, the top height of the convex portion is slightly less than the top height of the bearing member, and the bottom of the convex portion is flush with the bottom of the bearing member. The recess has a first insertion opening on the joint surface where it is located, and the recess has a second insertion opening at the bottom of the bearing member. One side of the recess corresponding to the top of the bearing member has a retaining wall.

[0008] The effects brought by the further setting are as follows: Since the bottom of the convex portion is flush with the bottom of the bearing member, the force between the positioning device and the installation plane is more uniform when installed and fixed to the installation plane through the second connecting portion, which can improve the stability during installation and fixation. The settings of the first insertion opening and the second insertion opening on the joint surface facilitate the insertion and extraction cooperation between the convex portion and the recess, and are convenient for the splicing and combination of the bearing members. The retaining wall can play a role in strengthening the overall structure of the bearing member, especially the structure between the convex portion and the recess, so that the width of the bearing member along the side-by-side connection direction can be made narrower, making the structure of the bearing member more compact.

[0009] Further, the joint surfaces on both sides of the bearing member are flat end faces, and the planes where the joint surfaces on both sides of the bearing member are located are arranged parallel to each other.

[0010] The effects brought by the further setting are as follows: It can increase the contact area of the joint surfaces between adjacent bearing members and improve the stability during splicing.

[0011] Further, the first connecting portion is a card joint that is engaged with the card slot at the bottom of the wire connector.

[0012] The effect of the further setting is that the bearing member can be fixed to the bottom of the wire connector by clamping the clamping joint with the clamping groove at the bottom of the wire connector, which is convenient for disassembly and assembly and is not likely to interfere with the wiring of the wire connector.

[0013] Further, a demolding port is provided at a position corresponding to the clamping joint on the support surface.

[0014] The effect of the further setting is that it is convenient for demolding after the integral injection molding of the bearing member.

[0015] Further, there is at least one convex part and its corresponding concave part on the bearing member, and these convex parts and concave parts are symmetrically arranged along the center of the joint surface.

[0016] The effect of the further setting is that when a plurality of bearing members are connected side by side, the convex part of one of the bearing members at the farthest end in the parallel connection direction can be aligned with the convex part of another bearing member after being reversed, so that the force application between the positioning device and the installation plane can be more balanced, thereby improving the stability.

[0017] Further, there is at least one second connection part on the convex part, and these second connection parts are symmetrically arranged along the center of the joint surface.

[0018] The effect of the further setting is that when a plurality of bearing members are connected side by side, the second connection part of one of the bearing members at the farthest end in the parallel connection direction can be aligned with the second connection part of another bearing member after being reversed, so that the force application between the positioning device and the installation plane can be further more balanced, thereby improving the stability.

[0019] Further, a groove for accommodating the conductive part is provided on the support surface, and openings are provided at both ends of the groove at the joint surfaces on both sides of the bearing member, and the grooves on the support surface can be communicated with each other when a plurality of bearing members are spliced side by side.

[0020] The effect of the further setting is that the groove can be used to accommodate the conductive part for paralleling each wiring unit of the wire connector, which has a shielding and protecting effect on the conductive part and can improve the safety during use. Description of the Drawings

[0032] Embodiment 1 of the positioning device of the wire connector of the present invention is as Figures 1-9 shown: It includes a carrier member 1 that can be spliced side by side with other carrier members 1 (the splicing combination state is as Figures 5-7 shown), the number of the carrier members 1 can be selected according to the specifications of the wire connector 2, for example, according to the width of the wire connector 2, and the carrier member 1 is as Figures 1-2The whole shown is flat, and includes a support surface 11 at its top and joint surfaces 12 on both sides along the splicing direction. The support surface 11 is arranged on the wide surface of the flat load-bearing member 1, and the two joint surfaces 12 are respectively arranged on the two opposite narrow surfaces of the flat load-bearing member 1. The joint surface 12 of the load-bearing member 1 can be mutually attached to the joint surface 12 of other load-bearing members 1 when arranged side by side. The mutual attachment can refer to the mutual attachment between the joint surfaces 12 on different sides of two adjacent load-bearing members 1, or the mutual attachment between the joint surfaces 12 on the same side of two adjacent load-bearing members 1. The support surface 11 is in mating contact with the bottom of the wire connector 2 for support, and a first connection portion 15 for connecting and fixing with the wire connector 2 is arranged on the support surface 11. The first connection portion 15 is a card joint for mating and clamping with the bottom slot 21 of the wire connector 2. In order to enable the wire connector 2 to be connected to multiple load-bearing members 1, multiple slots 21 arranged along the side-by-side splicing direction of the load-bearing member 1 are arranged at the bottom of the wire connector 2. The side-by-side connected load-bearing members 1 can maintain the relative fixation of the positions between the load-bearing members 1 based on their connection with the wire connector 2. Corresponding positions on the joint surfaces 12 on both sides of the load-bearing member 1 are respectively provided with a convex portion 13 protruding laterally along the splicing direction and a concave portion 14 for mating and inserting with the convex portion 13. A second connection portion 17 for connecting and fixing with the installation plane is arranged on the convex portion 13. The second connection portion 17 is preferably a through hole for passing a bolt. The load-bearing member 1 and the wire connector 2 can be integrally fixed on the installation plane through the screwing fit of the bolt with the installation plane. Of course, other connection structures can also be adopted between the second connection portion 17 and the installation plane, such as a clamping structure. When multiple load-bearing members 1 need to be spliced side by side and combined for use based on the specification of the wire connector 2, these load-bearing members 1 can act between the installation plane and the wire connector 2 at the same time, playing a certain supporting role for the bottom of the wire connector 2, making the connection between the wire connector 2 and the installation plane more stable.

[0033] The top height of the convex portion 13 is slightly less than the top height of the load-bearing member 1, and the bottom of the convex portion 13 is flush with the bottom of the load-bearing member 1. This enables the bottom of the convex portion 13 and the bottom of the load-bearing member 1 to be in flat contact with the installation plane when the convex portion 13 is installed and fixed on the installation plane by the second connection portion 17, thereby improving the stability during installation and fixation.

[0034] A first insertion opening 141 is arranged on the joint surface 12 where the concave portion 14 is located. The first insertion opening 141 can allow the convex portion 13 of an adjacent load-bearing member 1 to be laterally inserted into the concave portion 14.

[0035] The concave portion 14 is provided with a second insertion opening 142 at the bottom of the bearing member 1. The second insertion opening 142 allows the convex portion 13 of an adjacent bearing member 1 to be vertically inserted into the concave portion 14. One side of the concave portion 14 corresponding to the top of the bearing member 1 has a retaining wall 143. The side of the retaining wall 143 facing the concave portion 14 forms the inner wall of the concave portion 14 and can form a limiting fit with the convex portion 13 of an adjacent bearing member 1. The side of the retaining wall 143 facing the support surface 11 is flush-connected to the support surface 11. The setting of the retaining wall 143 can not only be used to limit the convex portion 13 inserted therein, but also improve the strength of the bearing member 1. In particular, it can reinforce the connection part between the convex portion 13 and the concave portion 14, so that the distance between the convex portion 13 and the concave portion 14 can be smaller, thereby making the lateral width of the bearing member 1 narrower, and further improving the adaptability to wire connectors 2 of different specifications.

[0036] In the present invention, there is at least one convex portion 13 and its corresponding concave portion 14 on the bearing member 1. There is at least one second connection portion 17 on the convex portion 13, and these convex portions 13, concave portions 14, and second connection portions 17 are all symmetrically arranged along the center of the joint surface 12. In Embodiment 1, there are two convex portions 13 and two concave portions 14. The two convex portions 13 are both arranged on the joint surface 12 on one side of the bearing member 1, and the two concave portions 14 are correspondingly arranged on the joint surface 12 on the other side of the bearing member 1 opposite to the convex portions 13. There is a center line a on the joint surface 12 of the bearing member 1 (as Figure 3 shown). The two convex portions 13 and the concave portions 14 are both symmetrically arranged along the center line a on the joint surface 12 where they are located.

[0037] As Figures 5-7 can be seen, when several bearing members 1 are spliced and connected to the bottom of the wire connector 2, the convex portion 13 of the bearing member 1 at the outermost end in one direction along its side-by-side splicing direction extends out from one side of the wire connector 2. The bearing member 1 at the outermost end in the other direction along its side-by-side splicing direction can be rotated to be connected to the wire connector 2, so that it fits with the joint surface 12 on the same side of the adjacent bearing member 1, and its convex portion 13 can extend out from the other side of the wire connector 2. Moreover, the convex portions 13 and the second connection portions 17 extending out from both sides of the wire connector 2 are symmetrically arranged. Therefore, when the positioning device is installed and fixed on the installation plane through the second connection portion 17 of the convex portion 13, the force application is relatively balanced, and the stability of the installation and fixation can be improved. The rotation of the bearing member 1 relative to the wire connector 2 means that the bearing member 1 rotates 180 degrees around its central position.

[0038] In addition, the joint surfaces 12 on both sides of the bearing member 1 are preferably flat end faces, and the planes where the joint surfaces 12 on both sides of the bearing member 1 are located are arranged parallel to each other. This enables the joint surfaces 12 of adjacent bearing members 1, especially the joint surfaces 12 on the same side, to be in flat contact when they are fitted together, and increases the contact area between the two, thereby improving the stability after splicing connection and reducing the sway of the bearing member 1.

[0039] A groove 18 for accommodating the conductive member 22 is formed on the support surface 11. The conductive member 22 is a component for electrically connecting different wiring units. Openings are provided at both ends of the groove 18 at the joint surfaces 12 on both sides of the bearing member 1. The grooves 18 on the support surface 11 can communicate with each other when a plurality of bearing members 1 are spliced side by side. The groove 18 can play a role in covering and protecting the conductive member 22, improving safety. If the conductive member 22 is connected upward to the bottom of the wire connector 2, it can also play a role in preventing the conductive member 22 from falling out downward.

[0040] In order to enable the groove 18 of the bearing member 1 at the farthest end to be connected to the groove 18 of the adjacent bearing member 1 after being turned around and connected to the wire connector 2, the groove 18 is preferably arranged at the central position of the support surface 11, and two first connection portions 15 are symmetrically arranged on both sides of the groove 18. The two first connection portions 15 can still be aligned and inserted into the card slots 21 on the wire connector 2 after the bearing member 1 is turned around.

[0041] The bearing member 1 can be formed by injection molding. In order to facilitate the injection molding and the formation of the card joint at the same time, a demolding port 19 is arranged at the position corresponding to the card joint on the support surface 11. The demolding port 19 is convenient for the mold to be removed when the card joint is formed.

[0042] Figures 8-9 The state diagrams of a single bearing member 1 used alone and two bearing members 1 used in a spliced combination are respectively shown. The second connection portions 17 on the convex portions 13 extending from one side or both sides of the wire connector 2 can be used to stably install and fix it on the installation plane.

[0043] Embodiment 2 of the present invention is as Figure 10 shown. The main difference from Embodiment 1 is that there is one convex portion 13 and one concave portion 14 on each of the joint surfaces on both sides of the bearing member 1, and both the convex portion 13 and the concave portion 14 are arranged at the central positions of the joint surfaces 12 where they are located.

[0044] Embodiment 3 of the present invention is as Figure 11As shown, the main difference from Embodiment 1 is that there are two convex portions 13 and two concave portions 14 on the joint surfaces on both sides of the bearing member 1. However, the two convex portions 13 are respectively arranged on the two joint surfaces, and the two concave portions 14 are also respectively arranged on the two joint surfaces. Moreover, the two convex portions 13 are circumferentially symmetric about the center of the bearing member 1. With such a structure, when connecting the bearing members 1 at the outermost ends side by side, there is no need to reverse the installation. The second connecting portions 17 on the convex portions 13 protruding from the two diagonal corners of the wire connector can also install and fix it on the installation plane.

[0045] The above embodiments are only one of the preferred specific embodiments of the present invention. All the common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are included in the protection scope of the present invention.
