Connector terminal position retainer

Abstract

The utility model relates to a connector terminal position retainer, which comprises three components, namely a terminal, a plug shell and a terminal position retainer, a terminal main body is cylindrical, and one end of the terminal main body is provided with a terminal bulge and a terminal groove which are close to each other and circularly surround; a plug shell main body is cylindrical, and one end of the plug shell main body is provided with a concave shell hanging table; the terminal position retainer is provided with an avoiding cavity, one end of the avoiding cavity is provided with an unlocking boss, and the inner side of the avoiding cavity is a limiting wall. The external diameter of one end of the plug housing is larger than that of one end of the terminal, thereby facilitating mutual clamping. According to the utility model, the trigger structure matched with the terminal is additionally arranged on the terminal position retainer, so that the terminal position retainer cannot be locked when the terminal is not arranged in the shell; only after the terminal is normally assembled in place, the terminal position retainer can be pushed by triggering the terminal position retainer unlocking structure. The condition that the terminal cannot be normally installed due to the fact that the terminal position maintaining piece is pushed to the locking position when the terminal is not installed in the shell can be effectively avoided.

Description

Technical Field

[0001] The utility model belongs to the field of new energy connectors, and in particular relates to a connector terminal position retaining member. Background Art

[0002] The conventional terminal position retainer does not have the initial position retaining 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 position retainer to be out of the initial position, resulting in the terminal being unable to be installed normally.

[0003] Chinese patent CN214625474U discloses a connector and a connector assembly. The connector includes: an outer shell; and a terminal position retainer, the terminal position retainer is detachably mounted on the end of the outer shell, and a mating feature that can be mated with a corresponding mating connector is formed on the terminal position retainer, so that the connector can be mated with the corresponding mating connector. In the utility model, when it is necessary to change the model identification feature on the connector, it is only necessary to replace the terminal position retainer on the connector without replacing the entire outer shell, so the cost is low and it is very convenient to use.

[0004] However, the above patent still fails to solve the problem that the initial position holding function is cumbersome and easy to touch by mistake. Utility Model Content

[0005] The utility model adds a trigger structure that matches the terminal to the terminal position retaining member, so that the terminal position retaining member cannot be locked when the terminal is not installed in the housing; only after the terminal is normally assembled in place, the terminal position retaining member unlocking structure is triggered to push the terminal position retaining member. This can effectively avoid the situation where the terminal position retaining member is pushed to the locking position when the terminal is not installed in the housing, thereby causing the terminal to be unable to be installed normally.

[0006] The specific technical solution of the utility model is as follows:

[0007] A connector terminal position retainer, characterized in that it comprises three components: a terminal, a plug housing, and a terminal position retainer;

[0008] The terminal body is cylindrical, and one end is provided with a closely adjacent circular terminal protrusion and terminal groove;

[0009] The plug housing body is cylindrical, and a concave housing hanging platform is provided at one end;

[0010] The terminal position retaining member is provided with an avoidance cavity, one end of the avoidance cavity is provided with an unlocking boss, and the inner side is a limiting wall;

[0011] The outer diameter of one end of the plug housing is larger than the outer diameter of one end of the terminal, so as to facilitate mutual engagement.

[0012] Furthermore, a first protrusion and a second protrusion are sequentially arranged on the plug housing from the outside to the inside, and the two protrusions are arranged on the edge of the housing hanging platform.

[0013] Furthermore, the terminal position retaining member is provided with a positioning groove which cooperates with the protrusion.

[0014] When the terminal is not installed in the plug housing, the lower wall of the positioning groove of the terminal position retaining member is restricted between the first protrusion and the second protrusion of the housing and cannot move axially;

[0015] When the terminal is installed in the housing, the lower side of the terminal protrusion is buckled with the housing hanging platform to fix the axial position of the terminal;

[0016] At the same time, the terminal protrusion lifts the unlocking boss of the terminal position retaining member, so that the lower wall of the positioning groove passes over the second protrusion, and the axial position of the terminal position retaining member is unlocked.

[0017] Further, the terminal position retaining member is pressed axially so that the positioning groove completely passes over the second protrusion and reaches the terminal position retaining position;

[0018] At this time, the limiting wall of the terminal position retaining member cooperates with the housing hanging platform, so that the housing hanging platform cannot be deformed outward, thereby achieving the function of retaining the terminal position.

[0019] The terminal is cylindrical, and the terminal protrusion and the terminal groove are completely circular, so that the terminal can be installed into the plug housing in any axial direction.

[0020] Furthermore, when the terminal is installed in the plug housing, the avoidance cavity provided on the terminal position retaining member enables the housing hanging platform to expand outward, so that the terminal can pass over the housing hanging platform and reach the terminal fixed position, and the housing hanging platform cooperates with the terminal protrusion to prevent the terminal from withdrawing.

[0021] The advantages and effects of this application are as follows:

[0022] 1. The utility model adds a trigger structure that cooperates with the terminal on the terminal position retaining member, so that the terminal position retaining member cannot be locked when the terminal is not installed in the housing;

[0023] 2. The utility model can push the terminal position retainer only after the terminal is properly assembled in place by triggering the unlocking structure of the terminal position retainer. This can effectively avoid the situation where the terminal position retainer is pushed to the locking position when the terminal is not installed in the housing, thereby causing the terminal to be unable to be installed normally.

[0047] The plug housing 120 is cylindrical in shape, and a concave housing hanging platform 123 is provided at one end;

[0048] The terminal position retaining member 130 is provided with an avoidance cavity 131, one end of the avoidance cavity 131 is provided with an unlocking boss 132, and the inner side is a limiting wall 133;

[0049] The outer diameter of one end of the plug housing 120 is larger than the outer diameter of one end of the terminal 110, so as to facilitate mutual engagement.

[0050] Preferably, a first protrusion 121 and a second protrusion 122 are sequentially arranged on the plug housing 120 from the outside to the inside, and the two protrusions are arranged on the edge of the housing hanging platform 123 .

[0052] Preferably, the terminal 110 is cylindrical, and the terminal protrusion 111 and the terminal groove 112 are completely circular, so that the terminal 110 can be installed in the plug housing 120 in any axial direction.

[0053] When the terminal 110 is installed in the plug housing 120, the avoidance cavity 131 provided on the terminal position retaining member 130 enables the housing hanging platform 123 to expand outward, so that the terminal 110 can pass over the housing hanging platform 123 and reach the fixed position of the terminal 110. The housing hanging platform 123 cooperates with the terminal protrusion 111 to prevent the terminal 110 from withdrawing.
