Description

[0002] In the design and manufacturing process of the connector, the positioning auxiliary device plays a crucial role, which is used to ensure the accurate alignment and fixation of the terminal in the assembly process. However, the positioning auxiliary device in the prior art has some design deficiencies when limiting two rows of terminals. For example, improper positioning of the limiting part may cause uneven stress on the corresponding thin shell area of the positioning auxiliary device when limiting the terminal, thereby increasing the risk of burst. This is particularly true when applied to power batteries, because power batteries have higher requirements for the current transmission capacity and stability of the connector than ordinary connectors. Although the prior art has provided a positioning auxiliary device in the connector to improve the stability of the connector to the terminal, such as the connector with terminal position guarantee disclosed in Chinese invention patent 202410503757.6, which maintains the terminal position guarantee member in the final locking position through one or more locking arms, which can provide reinforcement or auxiliary locking for the terminal and the terminal position guarantee. However, the following recessed part is used as the terminal intervention part, which can provide a smaller thickness of support, resulting in a smaller stress that can be used and a higher risk of burst. Moreover, the locking arm adopts an outwardly convex locking piece, which cannot be locked and fixed with the locking structure of the corresponding shell outer sidewall. SUMMARY

[0003] The utility model provides a patch type connector applied to power battery, such as double-row patch type connector, which has a more reasonable structure design, can provide more stress, is more stable for terminal positioning, and has a smaller risk of burst, aiming at the defects of the prior art.

The positioning auxiliary part 3 is assembled with the male shell 1 to realize auxiliary positioning of the terminals (mainly the female terminals). The positioning auxiliary part 3 comprises a main body part 31. A plurality of partition plates 32 (the number is determined according to the number of the terminals) are arranged on the main body part 31. An isolation plate 33 is arranged on each partition plate 32. Locking arms 39 are arranged on both sides of the positioning auxiliary part 3. Locking parts are arranged on the locking arms 39. First abutting tables 35 are arranged on the isolation plate 33 to position the female terminals inserted from above (i.e. above the first abutting tables 35). The locking parts are arranged on the inner side walls of the locking arms 39 and protrude inward. Positioning grooves 11 matched with the positioning auxiliary part 3 are arranged on the male shell 1. The locking parts protrude outward on the two side walls of the male shell 1. The locking arms 39 are inserted into the positioning grooves 11 and locked with the corresponding locking parts to realize locking of the positioning auxiliary part 3. In this way, the locking structure is arranged on the outer side of the male shell 1, which is simpler than the forming process of the locking structure arranged on the inner side and the mold is easier to manufacture.

[0022] The male terminals comprise a plurality of first male terminals 4 and a plurality of second male terminals 5 (for example, 6 terminals). The first male terminals 4 and the second male terminals 5 are arranged in two rows. The first abutting tables 35 are opposite to the first male terminals 4 to position the female terminals connected with the first male terminals 4.

[0023] The main body part 31 is divided into a plurality of terminal holes 34 by the partition plates 32 and the isolation plates 33. The second male terminals 5 are opposite to the terminal holes 34. The female terminals connected with the second male terminals 5 are inserted into the terminal holes 34.

[0025] Side limiting parts 37 are arranged on the side walls of the partition plates 32. Upper limiting parts 38 are arranged on the bottom surface of the isolation plate 33. The side limiting parts 37 and the upper limiting parts 38 have inclined surface structures to form narrow opening structures. The narrow opening structures tightly hold the female terminals connected with the second male terminals 5, i.e. the female terminals are tightened from the surroundings.

[0026] The first abutting platform 35 and the second abutting platform 36 each have an inclined section and a horizontal section behind the inclined section.

[0027] As shown in Figures 2-5 The positioning slot 11 extends upward from the bottom surface of the male shell 1, and the two locking arms 39 of the positioning auxiliary part 3 extend upward.

[0028] The locking part includes a first locking part 12 and a second locking part 13, and the second locking part 13 is arranged in an up-down structure with the first locking part 12; the locking part includes a first locking part 310 and a second locking part 311, and the second locking part 311 is located above the first locking part 310; the first locking part 310 and the second locking part 311 are buckled on the first locking part 12 and the second locking part 13, respectively, to lock the positioning auxiliary part 3 and the male shell 1.

[0029] The outer ends of the first locking part 12 and the second locking part 13 are in a pointed structure with the upper and lower surfaces inclined, and the upper portions of the first locking part 310 and the second locking part 311 are provided with inclined surfaces 312. When the positioning auxiliary part 3 is installed, the inclined surface 312 of the second locking part 311 first passes over the first locking part 12, and then passes over the second locking part 13, so that the first locking part 310 and the second locking part 311 are finally buckled on the first locking part 12 and the second locking part 13, respectively.

[0030] The reinforcing assembly part 21 is provided on both sides of the female shell 2, and the reinforcing sheet 6 is installed in the reinforcing assembly part 21.

[0031] It should be noted that the definition of the up-down direction and the like in the embodiment is based on the standard of the perspective shown in Figures 1-5 It can be understood that when the perspective changes, the up-down direction and the like will also change. Therefore, the description of the direction in the utility model should not be understood as a limitation on the product structure.

[0032] The utility model has been described in detail above, and the above description is only for the preferred embodiment of the utility model, which cannot limit the scope of the utility model, that is, any equivalent change and modification made within the scope of the application should still be included in the scope of the utility model.
