Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and specifically to an electrical connector. Background Technology

[0002] An electrical connector includes an insulating body and several terminals arranged to be inserted into the insulating body. By opening terminal holes on the insulating body corresponding to the terminals, the terminals are inserted into the corresponding terminal holes, making it convenient for different terminals to connect to different devices.

[0003] The terminals on existing electrical connectors are generally independent and separate. During assembly, each terminal needs to be inserted into its corresponding terminal hole. Furthermore, the large number of terminals that need to be inserted into the insulating body makes the assembly process time-consuming and results in low production efficiency of electrical connectors. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing an electrical connector that integrates independently separate terminals into a terminal block. During assembly, the terminal block can be neatly inserted into the terminal holes, reducing assembly time and improving the production efficiency of the electrical connector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electrical connector includes an insulating body and a first terminal block and a second terminal block inserted into the insulating body. Each of the first and second terminal blocks includes a plurality of terminals. Adjacent terminals on the same terminal block are integrally connected by a connecting plate. The insulating body has terminal holes for inserting terminals onto the terminal blocks, and notches for the connecting plate to pass through are formed between adjacent terminal holes. During assembly, the first and second terminal blocks are inserted into the insulating body as a whole. By integrally connecting adjacent terminals using a connecting plate to form a terminal block, the entire terminal block can be inserted into the terminal holes during assembly, eliminating the need to insert each terminal individually, reducing assembly time, and solving the problem of low production efficiency in electrical connectors.

[0007] As a preferred embodiment, a rearwardly extending protrusion is provided in the terminal hole. The protrusion extends along the direction of terminal insertion. During assembly, the protrusion contacts the terminal to limit its position.

[0009] As a preferred embodiment, the connecting plate is a rearwardly convex U-shape.

[0010] As a preferred embodiment, the terminal sidewall is provided with barbs, and a first step is provided in the terminal hole to cooperate with the barbs to prevent the terminal from being dislodged from the terminal hole. The first step faces downward, and during assembly, the barbs are embedded in the first step.

[0011] As a preferred embodiment, the system also includes a cover plate. The insulating body has a mounting groove for mounting the cover plate, the mounting groove is connected to the terminal hole, the cover plate has positioning buckles on both sides, and the mounting groove has a positioning groove on its side wall. During assembly, the positioning buckles are embedded in the positioning groove.

[0012] As a preferred embodiment, the terminal has a welding end for welding wires, and the cover plate has several through slots that extend through both sides of the cover plate for the welding ends to extend through. After the welding ends extend out of the through slots, they bend forward, and a partition strip is provided between adjacent through slots to separate adjacent welding ends.

[0013] As a preferred embodiment, the welding end includes a first welding end of a terminal on a first terminal block and a second welding end of a terminal on a second terminal block, the first welding end and the second welding end being staggered vertically, the cover plate having a second step, and the through groove including a first through groove and a second through groove corresponding to the first welding end and the second welding end respectively, the first through groove and the second through groove being distributed on the upper and lower sides of the second step.

[0014] As a preferred embodiment, the cover plate has guide blocks protruding outward on both sides, and the inner wall of the mounting groove has a first guide groove corresponding to the guide blocks.

[0015] As a preferred embodiment, the inner sidewall of the mounting groove is further provided with a second guide groove, which is directly opposite the positioning groove. The end of the second guide groove directly opposite the positioning groove has a second guide surface that is inclined outward from the bottom wall of the second guide groove.

[0016] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, by using a connecting plate to connect adjacent terminals to form a terminal block, the terminal block can be inserted into the terminal hole in an orderly manner during assembly, eliminating the need to insert the terminals into the terminal hole one by one, reducing assembly time and improving the production efficiency of electrical connectors.

[0027] like Figure 1-4As shown, this utility model discloses an electrical connector, including an insulating body 10 and a first terminal block and a second terminal block inserted into the insulating body 10. Both the first and second terminal blocks include a plurality of terminals. Adjacent terminals on the same terminal block are integrally connected by a connecting plate 32. The insulating body 10 has terminal holes 16 for inserting terminals onto the terminal blocks. Notches for the connecting plate 32 to pass through are formed between adjacent terminal holes 16. During assembly, the first and second terminal blocks are inserted into the insulating body 10 in a row. A rearwardly extending protrusion 15 is provided within the terminal hole 16, extending along the direction of terminal insertion. During assembly, the protrusion 15 contacts the terminal to limit its position; the insertion end of the protrusion 15 near the terminal hole 16 is provided with a first guide surface 151 to facilitate the insertion of the terminal into the terminal hole 16; the connecting plate 32 is a U-shaped protrusion extending backward; by setting the protrusion 15 and the connecting plate 32 to extend backward, the terminal can be limited, facilitating the insertion of the terminal into the terminal hole 16 and improving assembly efficiency; by connecting adjacent terminals with the connecting plate 32 to form a terminal block, the terminal block can be inserted neatly into the terminal hole 16 during assembly, eliminating the need to insert the terminals one by one into the terminal hole 16, reducing assembly time and solving the problem of low production efficiency of electrical connectors.

[0028] The terminal sidewall is provided with barbs 33, and a first step 161 is provided in the terminal hole 16 to cooperate with the barbs 33 to prevent the terminal from falling out of the terminal hole 16. The first step 161 faces downward. During assembly, the barbs 33 are embedded in the first step 161. By providing barbs 33 on the terminal, it is possible to prevent the terminal from falling out of the insulation body 10 after assembly, thereby improving the assembly stability.

[0029] It also includes a cover plate 20. The insulating body 10 has a mounting groove 11 for mounting the cover plate 20. The mounting groove 11 is connected to the terminal hole 16. The cover plate 20 has positioning buckles 21 on both sides. The mounting groove 11 has a positioning groove 12 on its side wall. During assembly, the positioning buckles 21 are embedded in the positioning groove 12. By setting the positioning buckles 21 and the positioning groove 12, the cover plate 20 can be stably installed in the mounting groove 11.

[0030] The terminal has a welding end for welding wires. The cover plate 20 has several through slots that penetrate both sides of the cover plate 20 for the welding ends to extend through. The welding end extends out of the through slot and then bends forward. A separator strip 24 protrudes between adjacent through slots to separate adjacent welding ends. The welding end includes a first welding end 30 of the terminal on the first terminal block and a second welding end 31 of the terminal on the second terminal block. The first welding end 30 and the second welding end 31 are staggered vertically. The cover plate 20 has a second step 25. The through slots include a first through slot 22 and a second through slot 23 corresponding to the first welding end 30 and the second welding end 31, respectively. The first through slot 22 and the second through slot 23 are distributed on the upper and lower sides of the second step 25. The separator strip 24 facilitates welding of wires in the welding part and avoids mutual interference between adjacent terminals. The step facilitates the distribution of the welding end positions.

[0031] The cover plate 20 has guide blocks 26 protruding outward on both sides, and the inner wall of the mounting groove 11 has a first guide groove 13 corresponding to the guide blocks 26; the inner wall of the mounting groove 11 also has a second guide groove 14, which is directly opposite to the positioning groove 12, and the end of the second guide groove 14 facing the positioning groove 12 has a second guide surface 141 that is inclined outward from the bottom wall of the second guide groove 14; by setting the guide groove structure, the cover plate 20 can be installed in the mounting groove 11 more conveniently.

[0032] The method of using this utility model is as follows: Insert the terminal block into the terminal hole 16, so that the barb 33 is locked in the first step 161, then insert the welding end into the through groove of the cover plate 20, and press down the cover plate 20 so that the positioning buckle 21 is locked into the positioning groove 12 to complete the assembly.

[0033] In summary, this utility model uses a connecting plate 32 to integrally connect adjacent terminals to form a terminal block, so that the terminal block can be inserted into the terminal hole 16 in an orderly manner during assembly, without having to insert each terminal into the terminal hole 16 one by one, thereby reducing assembly time and improving the production efficiency of electrical connectors.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
