Description

Technical Field

[0001] The utility model relates to the technical field of charger parts, and particularly relates to a pin of a shaver charger. Background Art

[0002] The main function of a shaver charger is to provide power for the shaver to ensure its normal operation. In the utility model patent with the patent publication number CN206076607U, a USB charging structure for a shaver is disclosed, which includes a pin base and a first pin and a second pin inserted into the pin base. The first pin and the second pin are further connected to a first conductive pin and a second conductive pin. The first conductive pin and the second conductive pin are respectively inserted into the first pin and the second pin. Since the surfaces of the first conductive pin and the second conductive pin and the first pin and the second pin are all smooth planes, when the first conductive pin and the second conductive pin are inserted into the first pin and the second pin and used for a long time, there is not enough friction between them, resulting in the pin coming out, affecting the charging effect. Summary of the Utility Model

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defect that when the first conductive pin and the second conductive pin are inserted into the first pin and the second pin and used for a long time in the prior art, there is not enough friction between them, resulting in the pin coming out and affecting the charging effect, so as to provide a pin of a shaver charger with good connection effect.

[0004] To this end, the utility model provides a pin of a shaver charger. The shaver includes a pin base and a pin inserted into the pin base. The pin includes an insertion end connected to a conductive pin and a wire connection end at the other end. An anti-slip portion connected to the conductive pin is provided on the insertion end, and a through hole for the wire to pass through is provided at the wire connection end.

[0005] Further: The anti-slip portion includes a positioning seat and a first deformation block and a second deformation block which are arranged on the positioning seat and are oppositely arranged. An avoidance space for the deformation of the two is provided between the first deformation block and the second deformation block. A positioning block which abuts against the side wall of the circular hole in the pin base is arranged at the position of the positioning seat and the wire connection end. The positioning seat and the positioning block are coaxially arranged, and the diameter of the positioning block is larger than that of the positioning seat.

[0006] Further: The anti-slip portion includes a positioning seat and an insertion rod arranged on the positioning seat. A plurality of anti-slip strips which abut against the inner wall of the conductive pin are arranged on the outer part of the insertion rod.

[0007] Further: A circular groove for the pin base to be embedded to position the pin is provided at the connection position of the positioning block and the wire connection end.

[0008] Furthermore: the wire connecting portion is provided with an opening for the wire to pass through the through hole from the side, and the opening is provided in a trumpet-shaped structure.

[0009] The technical solution of the utility model has the following advantages:

[0010] 1. The utility model provides a plug pin for a shaver charger, and the conductive pin has a blind groove for inserting the plug pin. Compared with the prior art, an anti-slip portion is provided on the insertion end inserted into the blind groove. The setting of the anti-slip portion can increase the contact friction between the insertion end and the blind groove, thereby preventing the plug pin from separating from the conductive pin. Second, the setting of the perforation can allow the wire to pass through to connect the plug pin and avoid the wire from being desoldered.

[0011] 2. The utility model provides a plug pin for a razor charger, wherein the anti-slip portion includes a positioning seat and a first deformable block and a second deformable block arranged on the positioning seat. When the first deformable block and the second deformable block are inserted into the blind groove, the first deformable block and the second deformable block will shrink and deform from both sides toward the middle until the first deformable block and the second deformable block are completely inserted into the blind groove. Then, the first deformable block and the second deformable block will conflict with the inner side wall of the blind groove, thereby increasing the contact friction between the outer side wall of the first deformable block and the second deformable block and the inner side wall of the blind groove.

[0023] Embodiment

[0024] This embodiment provides a pin of a shaver charger. The shaver includes a pin socket and a pin inserted into the pin socket. The pin includes an insertion end 1 connected to a conductive pin and a wire connection end 2 at the other end. An anti-slip portion connected to the conductive pin is provided on the insertion end 1, and a through hole 3 for the wire to pass through is provided at the wire connection end 2.

[0025] The specific improvement is as follows: As Figure 1 shown, the conductive pin has a blind slot for the pin to be inserted. Compared with the prior art, an anti-slip portion is provided on the insertion end 1 inserted into the blind slot. Through the setting of the anti-slip portion, the contact friction between the insertion end 1 and the blind slot can be increased, thereby preventing the pin from separating from the conductive pin. And through the setting of the through hole 3, the wire can pass through to connect the pin, avoiding wire de-soldering.

[0026] On the basis of the above embodiments: The anti-slip portion includes a positioning seat 4, and a first deformation block 41 and a second deformation block 42 which are arranged on the positioning seat 4 and are oppositely arranged. An avoidance space for the deformation of the two is formed between the first deformation block 41 and the second deformation block 42. A positioning block 5 which abuts against the inner side wall of the circular hole in the pin socket is arranged at the position of the positioning seat 4 connected to the wire connection end 2. The positioning seat 4 and the positioning block 5 are coaxially arranged, and the diameter of the positioning block 5 is larger than that of the positioning seat 4.

[0027] Embodiment 1: As Figure 2 and Figure 3 shown, the anti-slip portion includes a positioning seat 4, and a first deformation block 41 and a second deformation block 42 which are arranged on the positioning seat 4. When the first deformation block 41 and the second deformation block 42 are inserted into the blind groove, the first deformation block 41 and the second deformation block 42 will shrink and deform from both sides to the middle until the first deformation block 41 and the second deformation block 42 are completely inserted into the blind groove. After that, the first deformation block 41 and the second deformation block 42 will abut against the inner side wall of the blind groove, so as to increase the contact friction force between the outer side walls of the first deformation block 41 and the second deformation block 42 and the inner side wall of the blind groove.

[0028] On the basis of the above embodiments: The anti-slip portion includes a positioning seat 4 and a plug rod 43 arranged on the positioning seat 4. A plurality of anti-slip strips 6 which abut against the inner wall of the conductive pin are arranged outside the plug rod 43.

[0029] Embodiment 2: As Figure 4 shown, the anti-slip portion includes a positioning seat 4 and a plug rod 43 arranged on the positioning seat 4. The plug rod 43 is inserted into the blind groove. During the insertion process, the anti-slip strips 6 outside the plug rod 43 will be in interference fit with the inner side wall of the blind groove, so as to increase the contact friction force between the anti-slip strips 6 and the inner side wall of the blind groove.

[0030] On the basis of the above embodiments: A circular groove 7 for the pin socket to be embedded to position the pin is arranged at the connection part of the positioning block 5 and the wire connection end 2.

[0031] The above specific improvement is: As Figure 2 and Figure 3 shown, a circular groove 7 is arranged at the connection part of the positioning end and the wire connection end 2. Generally, a soft material such as rubber is arranged in the circular hole of the pin socket. The soft material has a shape adapted to the circular groove 7, so that the pin can be better fixed in the circular hole and prevent its lateral movement.

[0032] On the basis of the above embodiments: An opening 8 for the wire to penetrate into the through hole 3 from the side is arranged on the wire connection part. The opening 8 is arranged in a horn-shaped structure.

[0033] The above specific improvement is: As Figure 3As shown, since the aperture of the perforation 3 is relatively small, it is rather laborious to thread the wire. Therefore, a flared opening 8 is provided on the side of the perforation 3, and the wire can be squeezed into the perforation 3 from the opening 8, making it more convenient to thread the wire in this way.

[0034] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
