When the male plug-in 100 is not plugged into the female plug-in, the limiting gasket 130 is under the elastic force of the spring 140, the plugging piece 132 is located at the rightmost end of the accommodating groove 114, when the male plug-in 100 is plugged into the female plug-in, the female plug-in extends into the first cavity 110, the limiting gasket 130 is pushed to move leftwards, the spring 140 is compressed, and at the moment, the male terminal is exposed out of the third through hole 131, so that the male terminal is convenient to be butted with the female terminal. That is, spacing gasket 130 carries on spacingly in, avoids influencing the butt joint of public terminal and female terminal, is favorable to further improving the accurate degree that public terminal and female terminal butt joint.

When the male and

female members

100 and 100 are separated, the female member exits the first cavity 110, and at this time, the spring 140 rebounds to bring the spacing washer 130 to the rightmost end of the receiving groove 114.

When the female connector 200 is inserted into the male connector, the auxiliary handle 300 moves upward along the sliding protrusion 203 by the sliding groove 332. The stable operation of the auxiliary handle 300 is ensured, and the accuracy of the mutual insertion of the male plug-in unit and the female plug-in unit 200 is improved.

Referring to fig. 19, when the male plug-in unit is not inserted into the female plug-in unit 200, the auxiliary handle 300 is mounted on the female plug-in unit 200, and a distance moving upward along the female plug-in unit 200 is reserved, and at this time, in order to limit the auxiliary handle 300 and prevent the auxiliary handle 300 from shaking, it is preferable that triangular protrusions 333 are provided on both sides of the auxiliary handle 300, specifically, both sides of the plate, V-shaped grooves 204 are provided on both sides of the female plug-in unit 200, and the triangular protrusions 333 are engaged with the V-shaped grooves 204 to limit the auxiliary handle 300. When the male plug-in unit is inserted into the female plug-in unit 200, the triangular protrusion 333 breaks away from the V-shaped groove 204 under the external force, and the auxiliary handle 300 moves upward.

When the male plug-in unit and the female plug-in unit 200 are inserted, the auxiliary handle 300 is installed on the female plug-in unit 200, the auxiliary handle 300 is moved to be aligned with the uppermost end of the female plug-in unit 200, in order to limit the auxiliary handle 300 and avoid the auxiliary handle 300 from shaking, a limiting table 207 is arranged on the female plug-in unit 200, the limiting table 207 is located above the V-shaped groove 204, and at the moment, the triangular protrusion 333 and the limiting table 207 are clamped with each other, so that the limiting of the auxiliary handle 300 is realized.

Specifically, the V-shaped groove 204 is formed by an arc-shaped protrusion 208 and a triangular protrusion 209, and the arc-shaped protrusion 208 is located above the triangular protrusion 209 with the V-shaped groove 204 formed therebetween. The triangular protrusion 209 can support the triangular protrusion 333, when the auxiliary handle 300 moves upward along the female plug 200, the triangular protrusion 333 can gradually move upward along the arc surface of the arc-shaped protrusion 208, and the arc-shaped protrusion 208 facilitates smooth upward movement of the triangular protrusion 333, has small resistance, and has small damage to the triangular protrusion 333. That is, the arc-shaped protrusion 208 can play a role of clamping the triangular protrusion 333 on one hand, and can be beneficial to the smooth moving of the triangular protrusion 333 out of the V-shaped groove 204 on the other hand.

Preferably, in order to improve the limit reliability, trapezoidal bosses 334 are fixedly arranged on two opposite side walls of two plates of the auxiliary handle 300, two trapezoidal grooves 206 are formed in two sides of the female plug-in unit 200, and when the male plug-in unit and the female plug-in unit 200 are inserted into each other, the trapezoidal bosses 334 are clamped in the trapezoidal grooves 206 and matched with the limit table 207 and the triangular protrusions 333 to form a double limit function.

The construction, features and functions of the present invention are described in detail in the embodiments illustrated in the drawings, which are only preferred embodiments of the present invention, but the present invention is not limited by the drawings, and all equivalent embodiments modified or changed according to the idea of the present invention should fall within the protection scope of the present invention without departing from the spirit of the present invention covered by the description and the drawings.
