The applicant finds that at present, the female end of the traditional connector is generally not provided with a protective device, when the female end is left aside, the battery cell at the female end is directly exposed in the air, dust and water enter the female end to easily influence the quality of the plug connector, and safety accidents are caused. And the jack at the female end is larger, so that the electric shock accident can be easily caused when the fingers of the young child extend into the jack.

Aiming at the problems, the embodiment of the utility model provides the connector protective cover which can effectively prevent water, dust and electric shock on the left female end, greatly reduce the occurrence probability of electric shock accidents, prolong the service life of the connector, has simple structure and lower cost, and is suitable for large-scale production.

The following describes the technical scheme of the embodiment of the present utility model in detail with reference to the accompanying drawings.

Example 1

Referring to fig. 1-3, fig. 1 is a schematic structural diagram of a connector protecting cover according to an embodiment of the utility model.

The connector protective cover of the utility model comprises a protective cover body 1. The shape of the protective cover body 1 is consistent with the shape of the female end of the connector, specifically, the shape of the protective cover body 1 is consistent with the cross-sectional shape of the head end of the female end, and the area of the protective cover body 1 is slightly larger than the cross-sectional area of the head end of the female end; the head end of the female end of the connector is the end provided with the jack 71, and the tail end of the female end of the connector is the end connected with the power line 8. The material of connector protective cover is plastics, preferably, the material of connector protective cover is rubber. The connector protective cover made of rubber is less prone to damage caused by impact cracking.

The periphery of the protective cover body 1 is provided with a folded edge 2, specifically, the edge of one side of the protective cover body 1 is provided with the folded edge 2, and the plane where the folded edge 2 is located is perpendicular to the plane where the protective cover body 1 is located, so that the folded edge 2 and the protective cover body 1 can form a groove 3. The groove 3 is matched with the head end of the female end, specifically, the size and shape of the groove 3 are consistent with the cross section of the head end of the female end, so that when the protective cover body 1 covers the female end, the groove 3 can just accommodate the head end of the female end, and meanwhile, the folded edge 2 can effectively cover a part of side surfaces of the female end. By the cooperation of the protective cover body 1 and the folded edge 2, the head end of the female end can be covered completely, so that the battery cell in the plug jack 71 is not directly exposed in the air any more. And through setting up hem 2, not only can strengthen the intensity of connector protective cover, can also further prevent dust and water to enter into the electric core through female end and the plane that connector protective cover contacted for waterproof dirt-proof effect is better, and then has effectively improved the life of connector.

Further, in order to strengthen the waterproof effect of connector protective cover, the inboard of hem 2 is equipped with ring channel 21, be equipped with the sealing washer in the ring channel 21, works as connector protective cover lid is in when female end is in the sealing washer in the middle of female end with the hem 2 can effectively strengthen the connector protective cover with the leakproofness between the female end, and then strengthened waterproof effect. Meanwhile, in order to facilitate the user to plug the connector protective cover, the connector protective cover further comprises anti-skid patterns 22, and the anti-skid patterns 22 are arranged on the outer side of the folded edge 2, so that when people plug the connector protective cover, the friction between hands and the connector protective cover is increased through the arranged anti-skid patterns 22, and the user can plug the connector protective cover more easily.

Further, in order to enable the protective cover body 1 to cover the female end of the connector stably and firmly, the pin 4 is disposed in the groove 3. The pins 4 are matched with the insertion holes 71 of the female end, that is, the number, distance, shape and size of the pins 4 are consistent with those of the insertion holes 71 of the female end, so that the pins 4 can be smoothly inserted into the insertion holes 71. It should be noted that, in another embodiment, in order to further increase the friction force between the pin 4 and the socket 71 and further improve the stability of the connector protecting cover on the female end, whether the shape of the socket 71 is circular, elliptical, rectangular or other polygonal, the cross-sectional shape of the pin 4 is rectangular, and the cross-section is the largest rectangle in the socket 71. I.e. the pin 4 is shaped and sized to fit the socket 71 or the cross section of the pin 4 is the largest rectangle in the socket 71. Further, the length of the pin 4 is 0-2mm less than the depth of the insertion hole 71, so that it is possible to prevent the problem that the securing effect is not good due to the pin 4 being too short, or the shield body 1 cannot directly contact the plug due to the pin 4 being too long, for example, when the insertion hole 71 is 7mm, the length of the pin 4 may be 5-7mm.

In a preferred embodiment, as shown in fig. 1-3, the connector shield cover further comprises a connection assembly 5, said connection assembly 5 being connected to one end of the shield cover body 1. Specifically, the connection assembly 5 includes a socket portion 51 and an extension portion 52; one end of the extension portion 52 is connected to the protective cover body 1, and the other end is connected to the socket portion 51. More specifically, the socket portion 51 is circular, and the diameter of the socket portion 51 is larger than a preset diameter, the preset diameter is the cross-section diameter of the power cord 8 of the connector, so that the socket portion 51 is sleeved on the power cord 8; the extending portion 52 is strip-shaped, and the length of the extending portion 52 is greater than a preset length; the preset length is the distance from the head end to the tail end of the female end. Therefore, the connector protective cover sleeved on the power line 8 can be effectively covered on the head end of the female end while saving cost.

The connection assembly 5 may be made of an inelastic plastic material or an elastic rubber material. Further, in order to reduce the production process, simplify the structure, and reduce the cost, it is preferable that the connection assembly 5 is integrally formed with the shield cover body 1. Through setting up coupling assembling 5, can effectively solve the circumstances that leads to connector protection lid to lose because of people throw away the lid randomly.

In the first embodiment of the utility model, when the female end of the connector is left aside, the connector protective cover can be firmly fixed on the female end by inserting the pins into the insertion holes of the female end, and then the head end of the female end can be covered by the cooperation of the protective cover body and the folded edge, so that the battery core in the insertion hole of the female end is not directly exposed in the air any more, and the occurrence of electric shock accidents caused by the fact that dust and water enter the insertion holes of the female end to cause short circuit of lines is prevented effectively, and meanwhile, the occurrence of electric shock accidents caused by the fact that fingers of children extend into the insertion holes to contact with the battery core in the insertion holes is prevented.
