Description

Technical Field

[0001] The invention belongs to the technical field of connector terminals, and in particular relates to a connector terminal position retaining member. Background Art

[0002] More and more application scenarios require high-voltage connectors to have additional functions to enhance terminal retention, and for this purpose, additional terminal position retaining parts are needed.

[0003] The conventional terminal position retainer does not have the initial position retention function and requires a strict operation sequence to be used normally. When the terminal is not installed in the housing, it is easy to touch by mistake, causing the terminal retainer to be out of the initial position, resulting in the terminal being unable to be installed normally. For example, the patent website discloses a connector and a connector assembly with a publication number of CN214625474U. Therefore, in view of the above problems, a connector terminal position retainer provided by the present invention is of great significance. Summary of the invention

[0004] The present invention provides a connector terminal position retaining piece. By adding a trigger structure that matches the terminal to the terminal position retaining piece, the terminal position retaining piece cannot be locked when the terminal is not installed in a shell. Only after the terminal is normally assembled in place, the terminal position retaining piece can be pushed by triggering the unlocking structure of the terminal position retaining piece. This can effectively avoid the situation where the terminal position retaining piece is pushed to the locking position when the terminal is not installed in the shell, thereby causing the terminal to be unable to be normally installed. In summary, the problems in the background technology are solved.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] A connector terminal position retainer of the present invention comprises a terminal, a plug housing and a terminal position retainer;

[0007] The terminal is provided with a terminal protrusion and a terminal groove at one end close to the plug housing;

[0008] The plug housing is provided with a first protrusion and a second protrusion on both sides of one end close to the terminal position retaining member, and a housing hanging platform is provided on both sides of one end close to the terminal position retaining member;

[0009] The inner walls on both sides of the terminal position retainer are provided with avoidance cavities, and the inner walls on both sides of the terminal position retainer are fixedly connected with unlocking bosses, the inner side of the terminal position retainer is provided with a limiting wall, and the terminal position retainer is provided with a pair of positioning grooves.

[0010] Furthermore, the terminal is cylindrical, and the terminal protrusion and the terminal groove are both completely circular.

[0011] Furthermore, the avoidance cavity and the shell hanging platform are both arc-shaped, and their widths and thicknesses are correspondingly equal, and the center of each avoidance cavity and the center of each shell hanging platform are located on the same straight line.

[0012] Furthermore, the width of the positioning groove is equal to the width of the first protrusion and the second protrusion, and the center of each positioning groove and the center of each first protrusion and each second protrusion are all located on the same straight line.

[0013] Furthermore, the width of the lower wall of the positioning groove is correspondingly equal to the distance between the first protrusion and the second protrusion.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) When a connector terminal position retainer in the present invention is used, a trigger structure that matches the terminal is added to the terminal position retainer. When the terminal is not installed in the housing, the terminal position retainer cannot be locked. Only when the terminal is normally assembled in place, the unlocking structure of the terminal position retainer is triggered to push the terminal position retainer;

[0016] (2) When in use, the connector terminal position retaining member of the present invention can effectively prevent the terminal position retaining member from being pushed to the locking position when the terminal is not installed in the housing, thereby causing the terminal to be unable to be normally installed.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figure 1-6 As shown, a connector terminal position retainer of the present invention includes a terminal 110, a plug housing 120 and a terminal position retainer 130;

[0030] The terminal 110 is provided with a terminal protrusion 111 and a terminal groove 112 at one end close to the plug housing 120;

[0031] The plug housing 120 is provided with a first protrusion 121 and a second protrusion 122 on both sides of one end close to the terminal position retaining member 130, and the plug housing 120 is provided with a housing hanging platform 123 on both sides of one end close to the terminal position retaining member 130;

[0032] The inner walls on both sides of the terminal position retainer 130 are provided with avoidance cavities 131, and the inner walls on both sides of the terminal position retainer 130 are fixedly connected with unlocking bosses 132, the inner side of the terminal position retainer 130 is provided with a limiting wall 133, and the terminal position retainer 130 is provided with a pair of positioning grooves 134.

[0033] The terminal 110 is cylindrical, and the terminal protrusion 111 and the terminal groove 112 are both completely circular, so that the terminal 110 can be installed in the plug housing 120 in any axial direction.

[0034] Among them, the avoidance cavity 131 and the shell hanging platform 123 are both arc-shaped, and their width and thickness are correspondingly equal, and the center of each avoidance cavity 131 and the center of each shell hanging platform 123 are located on the same straight line. When the terminal 110 is installed into the plug housing 120, the shell hanging platform 123 can expand outward, so that the terminal 110 can pass over the shell hanging platform 123 and reach a fixed position. At this time, the shell hanging platform 123 cooperates with the terminal protrusion 111 to prevent the terminal 110 from withdrawing.

[0035] Among them, the width of the positioning groove 134 is equal to the width of the first protrusion 121 and the second protrusion 122, and the center of each positioning groove 134 and the center of each first protrusion 121 and each second protrusion 122 are all located on the same straight line. When the terminal 110 is installed into the plug housing 120, each positioning groove 134 can be aligned with the corresponding first protrusion 121 and second protrusion 122 respectively.

[0036] The lower wall width of the positioning groove 134 is equal to the spacing between the first protrusion 121 and the second protrusion 122. When the terminal 110 is not installed in the plug housing 120, the lower wall of the positioning groove 134 is limited between the first protrusion 121 and the second protrusion 122 and cannot move axially.

[0037] The standard parts used in the application documents can all be purchased from the market.

[0038] The working principle of the present invention is:

[0039] When the present invention is in use, an unlocking boss 132 is provided on the terminal position retaining member 130, and unlocking is performed by cooperating between the unlocking boss 132 and the terminal protrusion 111. When the terminal 110 is not installed in the plug housing 120, the lower wall of the positioning groove 134 of the terminal position retaining member 130 is restricted between the first protrusion 121 and the second protrusion 122 of the plug housing 120 and cannot move axially; and when the terminal 110 is installed in the plug housing 120, the lower side surface of the terminal protrusion 111 cooperates with the housing hanging platform 123, thereby fixing the position of the terminal 110, and at the same time, the terminal protrusion 111 is locked. 11. Lift the unlocking boss 132 of the terminal position retaining member 130 so that the lower wall of the positioning groove 134 passes over the second protrusion 122. At this time, the terminal 110 can move downward in the axial direction, and the axial position of the terminal position retaining member 130 is unlocked. At this time, press the terminal position retaining member 130 so that the positioning groove 134 completely passes over the second protrusion 122 and reaches the position retaining position of the terminal 110. At this time, the limiting wall 133 of the terminal position retaining member 130 cooperates with the shell hanging platform 123, so that the shell hanging platform 123 cannot be deformed outward, thereby realizing the function of terminal position retention.
