[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] This application provides an insert-type relay that solves the problem that in some existing cases, when the bolt is loosened to release the contact between the bolt and the conductive clamp, the bolt can easily detach completely from the mounting hole, thus achieving efficient installation.

[0034] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0035] When wiring existing relays, bolts are used to abut against the conductive clips on the cables to form an electrical connection between the cables and the relays. However, in some cases, when the bolts are loosened to release the abutment between the bolts and the conductive clips, the bolts can easily come completely out of the mounting holes. Therefore, the electrical connection efficiency of the cables is low.

[0036] Research has found that, for example Figures 1-6 As shown, by defining the mounting hole, threaded hole, bolt stud, and bolt nut, it is possible to facilitate the bolt passing through the threaded hole to engage with the conductive clamp of the cable. At the same time, it can effectively reduce the problem that the bolt may easily detach completely from the mounting hole when the bolt is loosened to release the engagement with the conductive clamp, thus achieving efficient installation.

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] Example:

[0039] like Figures 1-6 As shown, a plug-in relay includes a relay body 1, which is plugged into an electrical connection base 2 via multiple connectors 10.

[0040] The relay body 1 has multiple slots, each slot consisting of an electrical wiring slot 11 and a conductive structure 12. The conductive structure 12 is embedded in the corresponding electrical wiring slot 11 and is electrically connected to the relay body 1.

[0041] Each of the slots has a corresponding mounting hole 13, each mounting hole 13 is connected to the corresponding electrical wiring groove 11, and each mounting hole 13 is provided with a bolt 131.

[0042] Each bolt 131 passes through a threaded hole on the corresponding conductive structure 12 and is threadedly connected to the relay body 1. Each bolt 131 extends into the interior of the corresponding conductive structure 12 and abuts against the conductive clip on the cable located in the wiring gap 121.

[0043] The depth of each mounting hole 13 is the same as the length of the corresponding bolt 131 stud, and the distance between the bottom end of each mounting hole 13 and the bottom end of the corresponding threaded hole is greater than the length of the corresponding bolt 131 nut.

[0044] By defining the mounting hole 13, threaded hole 1, bolt 131 stud, and bolt 131 nut, it is possible to facilitate the bolt 131 passing through the threaded hole to engage with the conductive clamp of a pair of cables. At the same time, it can effectively reduce the problem that the bolt 131 may easily detach completely from the mounting hole 13 when the bolt 131 is loosened to release the engagement of the conductive clamp, thus achieving efficient installation.

[0045] When working, the length of bolt 131 stud is the same as the depth of mounting hole 13. Therefore, during initial installation, bolt 131 is placed in mounting hole 13. At this time, bolt 131 nut is located outside mounting hole 13, which makes it easy to hold bolt 131 nut and rotate bolt 131 in the forward direction to install bolt 131.

[0046] Meanwhile, the distance between the low end of each mounting hole 13 and the low end of the corresponding threaded hole is greater than the length of the corresponding bolt 131 nut, that is, the total threaded depth of the threaded hole one of the conductive structure 12 is greater than the length of the corresponding bolt 131 nut. When the bolt 131 is rotated in the opposite direction, the high end of the bolt 131 nut is rotated to be flush with the high end of the mounting hole 13. At this time, the bolt 131 has not completely separated from the threaded hole one, and the bolt 131 is located inside the mounting hole 13, which can effectively prevent the bolt 131 from being completely separated from the mounting hole 13 when the bolt 131 is loosened to remove the bolt 131 from the conductive clamp. The bolt 131 is easily tightened again, and the problem of the bolt 131 being lost is easily solved.

[0047] Specifically, according to actual needs, for example, when the mounting hole 13, the threaded hole one, the bolt 131 stud and the bolt 131 nut are limited, the depth of the mounting hole 13 and the length of the bolt 131 stud are both 5 cm, the depth of the bolt 131 nut is 0.5 cm, and the total threaded depth of the threaded hole one on the conductive structure 12 is 1 cm.

[0048] As shown in Figures 2-3 and Figure 6 Each of the insertion slots is provided with a limiting block 132, and each of the limiting blocks 132 is fixedly connected with the corresponding conductive structure 12.

[0049] Each of the limiting blocks 132 is provided with a threaded hole two matched with the bolt 131.

[0050] The bolt 131 passes through the corresponding threaded hole one and threaded hole two and abuts against the cable conductive clamp in the wiring gap 121, forming an electrical connection between the cable and the relay body 1.

[0051] By providing the limiting block 132, the stability of the bolt 131 abutting against the cable conductive clamp is further improved, thereby effectively reducing the problem of poor contact.

[0052] As shown in Figures 3-4 and Figure 6 Each of the conductive structures 12 is provided with a slot 111 below, and a plurality of slots 111 are located below the conductive structure 12 and communicate with the electrical wiring slot 11.

[0053] The plug-in connector 10 located below the conductive structure 12 is fixedly connected with the conductive structure 12 through the corresponding slot 111.

[0054] By providing the slot 111 and fixing the plug-in connector 10 below the conductive structure 12 with the conductive structure 12 through the corresponding slot 111, the disassembly of the conductive structure 12 can be realized, and the connection between the conductive structure 12 and the relay body 1 can be easily maintained.

[0055] As Figure 1 shown, after the relay body 1 is plugged with the electrical connection base 2, the relay body 1 and the electrical connection base 2 form a gap, and then the installation between the relay body 1 and the electrical connection base 2 is facilitated.

[0056] In operation, the cable conductor clamp is placed in the wiring gap 121 formed by the conductive structure 12 and the low end of the bolt 131, and the conductive clamp is abutted and loosened according to the rotating mode of tightening and loosening the bolt 131, so as to realize the connection of the cable on the relay body 1.

[0057] In summary, compared with the prior art, the following beneficial effects are achieved:

[0058] 1. By limiting the mounting hole, the threaded hole 1, the bolt stud and the bolt nut, the bolt can abut the cable conductor clamp through the threaded hole 1, and the problem that the bolt is easily completely separated from the mounting hole when the bolt is loosened to release the abutment of the conductor clamp by the bolt can be effectively reduced, and efficient installation is achieved.

[0059] 2. By setting the limiting block 132, the stability of the abutment of the cable conductor clamp by the bolt 131 is further improved by the limiting block 132, and the problem of poor contact can be effectively reduced.

[0060] 3. By opening the notch 111 and fixing the plug-in connector 10 below the conductive structure 12 through the corresponding notch 111 and the conductive structure 12, the disassembly of the conductive structure 12 can be achieved, and the connection between the conductive structure 12 and the relay body 1 can be easily maintained.
