When the female seat 1 of public seat 5 is connected, first recess 12 and clearance 13 produce the guide effect to public seat 5, and overall structure is convenient for the dismouting and easily implements.

Furthermore, a through hole 111 is axially formed in the middle of the female end positioning block 11, and the second connecting piece 3 is installed in the through hole 111; a first connecting member is disposed in the second groove 52, and the first connecting member can be inserted into the through hole 111 and connected to the second connecting member 3. When plugging, the through hole 111 plays a guiding role, guides an operator to enable the first connecting piece to be close to the second connecting piece 3 and to be sucked by the second connecting piece 3, and is convenient and quick to use.

Still further, an elastic member 4 is disposed in the through hole 111, and the first connecting member can pass through the elastic member 4 to be connected with the second connecting member 3. When the connector is plugged in and pulled out, the first connecting piece stretches off the elastic piece 4, the elastic piece 4 deforms along the radial outward direction, and at the moment, the elastic piece 4 generates resistance to the first connecting piece and clamps the first connecting piece tightly. The elastic part 4 is clamped with the first connecting part, and the connection stability is good. When the connector is plugged, the resistance of the elastic piece 4 and the suction of the second connecting piece 3 are both provided, and the two are mutually matched and enhance the plugging hand feeling.

Still further, first connecting piece includes connective bar 7, and the one end that connective bar 7 and second connecting piece 3 are connected is equipped with joint groove 71 along circumference, and joint groove 71 along the radial inwards concave establishment of connective bar 7, and elastic component 4 can the joint in joint groove 71. In this embodiment, the elastic member 4 is preferably a crown spring. The snap groove 71 is shaped to fit the crown spring. Because the crown spring is in a structure with large diameter at two ends and small diameter at the middle, when the connecting rod 7 is inserted into the crown spring, the connecting rod 7 firstly struts the head of the crown spring; with the insertion of the connecting rod 7, the diameter of the contacted crown spring is gradually reduced, and the insertion resistance is gradually increased. After the clamping groove 71 on the connecting rod 7 is inserted into a half, the resistance of the connecting rod 7 is gradually reduced, and finally the clamping groove 71 slides into the crown spring. The resistance is reduced from large to small during plugging, and the plugging hand feeling is further enhanced.

In this embodiment, the connecting rod 7 is made of ferromagnetic material, and the second connecting member 3 includes a magnet capable of attracting the connecting rod 7. The connecting rod 7 is preferably made of iron, cobalt, nickel or an alloy thereof, and the material is low in cost and convenient to use.

As shown in fig. 2, in the present embodiment, a plurality of female pin holes 112 are axially formed in the female positioning block 11, the female pin holes 112 surround the through holes 111, a female pin 2 is disposed in the female pin hole 112, one end of the female pin 2 is disposed in the female pin hole 112, and the other end of the female pin 2 penetrates through the female pin hole 112 and is disposed outside the female socket 1.

Further, with reference to fig. 1, a third groove 53 is formed at an end of the male seat 5 opposite to the second groove 52, a male end positioning block 51 is disposed at a bottom of the third groove 53, one end of the male end pin 6 penetrates through the male end positioning block 51 and is disposed in the second groove 52, and the other end of the male end pin 6 is disposed in the third groove 53. After the male socket 5 is connected with the female socket 1, the male pin 6 can be inserted into the female pin hole 112 and is in contact connection with the female pin 2, so that current and signal transmission is realized.

In particular, two positioning lugs 14 for fixing the female seat 1 are fixedly connected to the outer side wall of the female seat 1, and the two positioning lugs 14 are symmetrically arranged. The positioning lug 14 is provided with a screw hole, and a screw is arranged in the screw hole in a penetrating way to fix the female seat 1.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention.
