As shown in fig. 1, the needle holder 100 for a connector includes a first clamping portion 10 and a second clamping portion 20 which are connected and disposed at an acute angle, the first clamping portion 10 can abut against a press block 210 inside the connector 200, the second clamping portion 20 is provided with an anti-slip member 30, the anti-slip member 30 can abut against a housing of the connector 200, and the first clamping portion 10 and the second clamping portion 20 can approach each other to disengage the press block 210 from the terminal 300. The connector needle ejector 100 includes a first clamping portion 10 and a second clamping portion 20 disposed at an acute angle, the first clamping portion 10 can extend into the insertion hole 220 to eject the pressing block 210, and at the same time, a user holds the first clamping portion 10 and the second clamping portion 20, so that the first clamping portion 10 can apply a horizontal pushing force to the pressing block 210, and can apply an expanding force towards the second clamping portion 20 on the pressing block 210, the pressing block 210 receives forces in two directions, the connector needle ejector 100 is not easily ejected, meanwhile, the second clamping portion 20 is provided with the anti-slip member 30, after the anti-slip member 30 abuts against the shell of the connector 200, the friction force is large, even if the connector needle ejector 100 has a tendency of being ejected, the ejecting force of the pressing block 210 is insufficient to resist the friction force between the anti-slip member 30 and the shell of the connector 200, and the risk that the connector needle ejector 100 has being ejected is further avoided, thereby improving the stability of the connector needle ejector 100 in ejecting the pressing block 210 in the insertion hole 220 and improving the efficiency of the terminal 300.

Alternatively, the anti-skid member 30 is made of rubber. Not only can prevent the shell of the connector 200 from being damaged, but also can generate a certain amount of deformation, increase the contact area with the shell of the connector 200 and increase the friction force.

Preferably, the anti-slip member 30 is made of silica gel, and is soft in material and large in deformation.

The anti-slip member 30 may further wrap the end of the second clamping portion 20, so that the end of the second clamping portion 20 is in a non-sharp state, and the second clamping portion 20 is prevented from being scratched by an operator.

Preferably, as shown in fig. 2, in one embodiment, the anti-slip member 30 includes a plurality of anti-slip portions 31, and the plurality of anti-slip portions 31 are connected to the second clamping portion 20 and are spaced apart along the length direction of the second clamping portion 20. With the above arrangement, the plurality of anti-slip portions 31 can increase friction between the anti-slip member 30 and the housing of the connector 200, as compared to the anti-slip member 30 being a single piece.

Preferably, the surface of the anti-slip part 31 is arc-shaped. As the force applied by the operator increases, the contact area between the anti-slip portion 31 and the housing of the connector 200 gradually increases, if the anti-slip portion is square, the top surface of the anti-slip portion 31 will be recessed during the extrusion process, and the arc shape ensures gradual contact during the gradual contact of the anti-slip portion 31 with the connector 200, and the contact area with the housing of the connector 200 gradually and steadily increases.

Preferably, as shown in fig. 3, the anti-slip member 30 further includes a connecting portion 32, the connecting portion 32 is mounted on the second clamping portion 20, and the plurality of anti-slip portions 31 are all protruding from the connecting portion 32.

Optionally, a mounting groove (not shown) may be provided at the end of the second clamping portion 20 to facilitate quick positioning of the cleat 30.

Preferably, as shown in fig. 4, the free end of the first clamping part 10 is provided with an upwardly inclined slope 111, and the slope 111 can abut on the slope 211 of the front end of the pressing block 210. Wherein tilting upwards refers to a direction facing away from the second clamping portion 20. Through the above arrangement, the inclined surface 111 can extend into the gap formed by the slope surface 211 of the pressing block 210 and the terminal 300, compared with a simple sheet-shaped body, the above arrangement ensures that the bonding degree of the inclined surface 111 and the slope is better, so that the first clamping part 10 can better apply force towards the second clamping part 20 to the pressing block 210, and the ejection of the pressing block 210 is more labor-saving.

In one embodiment, as shown in fig. 4, a pressing portion 12 is protruding from a side of the free end of the first clamping portion 10 facing the second clamping portion 20, and the inclined surface 111 is a surface of the pressing portion 12 facing the outside. In this embodiment, the pressing portion 12 has a triangular shape, and in other embodiments, the pressing portion 12 may have a trapezoid shape, which is not limited herein. Preferably, the material of the pressing portion 12 may be silica gel, so that the friction between the pressing portion 12 and the pressing block 210 can be increased, and the pressing portion 12 is prevented from sliding out from the slope 211 of the pressing block 210.

In another embodiment, as shown in fig. 2 and 5, the inclined surface 111 is formed by bending the free end of the first clamping portion 10 upward. That is, the bent portions 11 shown in fig. 5 are simultaneously chamfered at the corners of the first clamping portion 10, preventing the tip of the first clamping portion 10 from scratching the operator.

Preferably, at least the outer surface of the first clamping part 10 is provided with an insulating layer. And in the operation process, the misoperation of operators is prevented from generating electric shock. Further preferably, the outer surfaces of the first clamping portion 410 and the second clamping portion 20 are provided with insulating layers, which more fully plays a role of insulation protection.

In the process of withdrawing the pin, since the elasticity of the pressing block 210 is in a certain range, such as an excessive pushing force or an excessive pressing force, the pressing block 210 is easily broken, so that the connector 200 cannot be plugged into the terminal 300 again.

In order to solve the above-described problem, as shown in fig. 2, the needle holder 100 for a connector further includes a stopper 40, one end of the stopper 40 is mounted on one of the first clamping portion 10 and the second clamping portion 20, the other end of the stopper 40 faces the other of the first clamping portion 10 and the second clamping portion 20, and the height of the stopper 40 between the first clamping portion 10 and the second clamping portion 20 is adjustable. It should be noted that, because the mounting surface of the front end of the first clamping portion 10 is smaller, the limiting member 40 is installed on the second clamping portion 20 more, through the above arrangement, before the needle is withdrawn, the operator can adjust the height of the limiting member 40, so that when the connector is clamped by the needle withdrawing device 100 under force, the first clamping portion 10 abuts against the end of the limiting member 40, and cannot be pushed down again, further, the pushing-down degree of the pressing block 210 is ensured to be within a proper range, the pressing block 210 is ensured to be separated from the terminal 300, the pushing-down degree cannot cause fracture failure of the pressing block 210, the service life of the connector 200 is prolonged, and the height of the limiting member 40 is adjusted for connectors 200 of different types before the needle withdrawing.

Specifically, as shown in fig. 2, the first clamping portion 10 or the second clamping portion 20 to which the stopper 40 is mounted is defined as a mounting portion, the stopper 40 is a screw, the screw is screwed to the mounting portion, and the connector needle holder 100 further includes a lock nut (not shown) screwed to the screw and capable of abutting against the mounting portion. Through the above arrangement, the nut is screwed up and abutted to the mounting portion, the height of the limiting member 40 is fixed, and the height of the limiting member 40 can be adjusted by unscrewing the nut.
