Detailed Description

Referring to fig. 1, a quick plug electric connector includes that public inserting 1 and female inserting 2, and female inserting 2 includes hollow casing 201, is provided with many contact pins 202 in the inner chamber of casing 201, and the trailing end of casing 201 is connected with the cable, and contact pin 202 is connected with the pencil in the casing 201 trailing end cable. The housing 201 is provided with receiving grooves 203 symmetrically on both inner sidewalls of the front portion of the inner cavity, and locking grooves 204 recessed at the bottom of the receiving grooves 203.

Referring to fig. 2, the male plug 1 includes a plug 101, the plug 101 is used for being inserted into a housing 201 of the female plug 2, a front portion of the plug 101 is provided with a jack 102 into which a pin 202 is inserted, a tail end of the plug 101 is also connected with a cable, and an electrode in the jack 102 is connected with a wire harness in the cable at the tail end of the plug 101. A cylindrical cavity 103 is arranged in the plug 101 along the width direction, guide holes 104 are arranged at two ends of the cavity 103, the guide holes 104 are coaxial with the cavity 103, one end of each guide hole 104 is communicated with the cavity 103, the other end of each guide hole extends to the side face of the plug 101, a guide rod 105 is movably arranged in each guide hole 104 in a penetrating mode, a pair of limiting blocks 106 are arranged in the cavity 103, a pair of strip-shaped moving pieces 108 are symmetrically arranged on the outer side of the plug 101, the moving pieces 108 are arranged along the length direction of the plug 101, one end of each guide rod 105 is connected with the corresponding limiting block 106, the other end of each guide rod 105 is connected with the corresponding moving piece 108, a spring 107 is arranged in the cavity 103 and located between the two limiting blocks 106, two ends of the spring 107 are respectively contacted with the two. This structure allows the guide bar 105 to move freely in the guide hole 104 without being separated from the guide hole 104.

A convex locking block 112 is arranged at the front end of the movable piece 108, and the shape of the locking block 112 is matched with that of the locking groove 204.

The male plug 1 and the female plug 2 are set to be in a separated state in an initial state. The use method of the electric connector comprises the following steps: simultaneously pressing the two movable pieces 108 by fingers until the movable pieces 108 cling to the side wall of the plug 101, and in the process, the spring 107 compresses and stores energy; the plug 101 is then fully inserted into the housing 201 with the locking block 112 just aligned with the locking slot 204; then, the movable piece 108 is released, at this time, the spring 107 extends to drive the two movable pieces 108 to move away from each other until the locking block 112 enters the locking groove 204, so that the male plug 1 and the female plug 2 are locked, and the plugging operation is completed. The operation steps of separating the male plug 1 from the female plug 2 are as follows: simultaneously, the two movable pieces 108 are pressed to separate the locking block 112 from the locking groove 204, and then the plug 101 is pulled out from the housing 201.

This electric connector passes through push type locking structure and inserts 1 with public and female 2 lockings of inserting together, simple structure, simple operation can realize quick plug and can guarantee the reliability of connecting.

In order to facilitate the pressing of the movable element 108, a pressing block 109 is fixed to an outer side wall of the movable element 108 in the present embodiment. And the outer side surface of the pressing block 109 is provided with an arc-shaped concave part 110, and the concave part 110 can increase the comfort degree when the movable piece 108 is pressed.

In addition, in order to prevent a finger from slipping when the pressing block 109 is pressed, a plurality of protrusions 111 are provided in the depression 110. The bumps 111 can increase the friction between the fingers and the pressing block 109 to prevent slipping.

Referring to fig. 1 and 2, an elastic block 205 is fixed to an inner top of the housing 201, and a notch 115 into which the elastic block 205 is inserted is opened at a front end of the plug 101. When the plug 101 is completely inserted into the housing 201, the elastic block 205 just enters the notch 115 and abuts against the front end of the plug 101, and after the plug is locked into the locking groove 204, the elastic force generated by the elastic block 205 enables the locking block 112 to downwards press the locking groove 204, so that the locking stability can be improved, and the plug-in of the male plug 1 and the female plug 2 is prevented from being slightly loosened.

The elastic block 205 in this embodiment is a silicone block, which is bonded and fixed to the housing 201.

In addition, the two movable pieces 108 are driven to move away from each other by the elastic force of the spring 107 completely in the embodiment. When the electrical connector is used for a long time, the spring 107 may lose part of its elastic force, so that the generated elastic force is not enough to drive the locking block 112 to abut against the locking slot 204, which affects the locking stability. Referring to fig. 2, in order to avoid this situation, in the present embodiment, a first magnet 113 is fixed symmetrically on both sides of the plug 101, and a second magnet 114 is fixed on the locking block 112 at a position corresponding to the first magnet 113, and the first magnet 113 and the second magnet 114 repel each other. The repulsive force between the first magnet 113 and the second magnet 114 can drive the moving member 108 to move away from the plug 101, and the repulsive force can compensate the lost elastic force of the spring 107, thereby ensuring that the locking block 112 can be reliably attached to the locking groove 204 all the time, and improving the reliability of the electrical connector.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
