Technical Field

[0001] The utility model belongs to the technical field of connectors, and particularly relates to a dustproof cover and a connector using the dustproof cover. Background Art

[0002] In the prior art, connectors are typically fitted with dust covers to protect them from external dust, moisture, and other environmental influences when not in use. These covers come in two types: rubber and metal. Rubber dust covers offer excellent sealing properties, but they carry a risk of falling off in harsh environments and exhibit poor stability. Metal dust covers, once locked to the socket, resist falling off and offer high structural strength, but they offer poor vibration resistance in harsh environments, creating noise pollution and the risk of connector damage. There is an urgent need to develop metal dust covers with superior vibration resistance. Utility Model Content

[0003] The purpose of the present invention is to solve the above problems in the prior art and provide a dust cover and a connector using the dust cover. The device has the advantages of simple and reasonable structure and good shock resistance through structural improvement.

[0004] One of the purposes of the present utility model is to provide a dustproof cover, comprising a cap, wherein the cap comprises a cover plate and a surrounding edge arranged on one end surface of the cover plate, wherein a through groove penetrating the side wall is provided on the surrounding edge, and a shockproof component is fixedly installed in the through groove, and the inner side of the shockproof component extends into the inner cavity of the surrounding edge and is exposed to one side of the inner cavity.

[0005] As a preferred solution, the shock-proof component includes an elastic pad and a pressure plate, and the elastic pad is pressed and fixed in the through groove by the pressure plate.

[0006] As a preferred solution, an anti-slip groove is formed on the end surface of the contact side of the pressure plate and the elastic pad. The pressure plate fixes and squeezes the elastic pad so that the back side of the elastic pad is squeezed and deformed into the anti-slip groove.

[0007] As a preferred solution, a mounting step is formed on the periphery of the through slot, and a threaded hole is formed on the mounting step.

[0008] As a preferred solution, the elastic pad includes an elastic pad body, and a pressing edge is formed along the periphery of the elastic pad body, and the pressing edge is pressed and fixed on the installation step by a pressing plate.

[0009] As a preferred solution, a fixing platform is provided on the installation step, and a notch is formed at the corresponding position of the pressure edge and the fixing platform, and the notch cooperates with the fixing platform; a threaded hole for fixing the pressure plate is provided at the fixing platform, and the screw passes through the through hole of the pressure plate and is screwed into the threaded hole.

[0010] As a preferred solution, a ridge is formed on the end surface of the elastic pad body close to the inner cavity of the surrounding edge.

[0011] As a preferred solution, the length setting direction of the ridge is perpendicular to the axial direction of the cap.

[0012] As a preferred solution, a locking piece is fixedly provided on the inner side wall of the surrounding edge, and the locking piece is used to be locked and matched with the connector plug interface.

[0013] As a preferred solution, the surrounding edge adopts a square ring structure for matching with the rectangular interface of the connector plug interface.

[0014] As a preferred embodiment, through grooves are formed at symmetrical positions on one set of opposite side walls of the surround, and the shockproof components are fixed in the through grooves; grooves are formed at symmetrical positions on another set of opposite side walls of the surround, and the locking plates are fixed in the grooves.

[0015] A second object of the present utility model is to provide a connector, which includes a connector body, and any of the above-mentioned dust covers is installed on the connector plug interface of the connector body.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] First, the utility model provides a dust cover with advantages such as simple structure and good shock resistance. The dust cover can maintain stability under severe vibration conditions by fixing the shockproof component in the through groove of the surrounding edge.

[0018] Secondly, the present invention features a through-slot formed on the edge of the dust cover. The shock-absorbing components consist of an elastic pad, a pressure plate, and screws. First, the elastic pad is inserted into the through-slot, and then the pressure plate is installed to press and secure the pad. When the dust cover is assembled with the connector, the elastic pad is elastically compressed, effectively preventing the connector from vibrating and falling off under severe vibration conditions.

[0019] Third, in this solution, in order to further enhance the shock-resistant effect of the dust cover, the elastic pad is provided with a number of ridges on one side of the inner cavity of the dust cover. When the dust cover is docked with the corresponding connector interface, the ridges on the inner end face of the elastic pad will be elastically compressed to enhance the shock-resistant function of the dust cover and enhance the fixing effect to a certain extent. This can prevent the dust cover from colliding with the connector and damaging the connector due to severe vibration.

[0020] Fourthly, this solution also takes into account that after the dust cover is installed and docked, in order to solve the problem of the dust cover falling off easily, a locking plate is provided on the inner wall of the dust cover. The locking plate can cooperate with the locking groove of the connector. When the dust cover is buckled into place, the elastic end of the locking plate undergoes elastic deformation during locking, and rebounds to fit into the locking groove of the connector socket to achieve locking, thereby effectively preventing the dust cover from falling off.

[0047] Example 1

[0048] like Figure 1-6 As shown, this embodiment provides a dustproof cover, including a cap 1 and a shockproof component 2, the cap 1 includes a cover plate 11 and a surrounding edge 12, the surrounding edge 12 is located on one side end surface of the cover plate 11, as shown in the figure, the surrounding edge 12 of this solution is a square ring structure, and the surrounding edge 12 has an inner cavity 18 with a rectangular opening in cross section, and a shockproof component 2 is provided on at least one group of opposite side walls of the surrounding edge 12. Specifically, a through groove 13 is formed on the side of the surrounding edge 12. By arranging the shockproof component 2 in the through groove 13, this solution can ensure that the dustproof cover 100 remains stable under severe vibration conditions after being fixed and installed. The dustproof cover 100 of this solution has the advantages of simple structure and good shock resistance. It should be pointed out that the cap 1 of the present embodiment is not limited to the above-mentioned square ring structure, and can also be modified and applied as follows according to the structure of the connector plug interface 201. For example, the edge 12 adopts a circular ring structure or a polygonal ring structure, and the shockproof component 2 needs to be set on the edge 12 according to actual needs. The number and shape of the shockproof component 2 can also be adaptively adjusted.

[0049] like Figure 5 As shown, the through groove 13 of this solution is formed with a mounting step 14 inside, and a fixing platform 15 is formed at the corner of the mounting step 14, and a threaded hole 16 is provided on the fixing platform 15; the shockproof component 2 is pressed and fixed on the mounting step 14, and the shockproof component 2 includes an elastic pad 21, a pressure plate 22 and a screw 23. The pressure plate 22 presses and fixes the elastic pad 21 in the through groove 13, and the inner side of the elastic pad 21 extends into the inner cavity 18 and is exposed. The specific installation method is: first install the elastic pad 21 into the through groove 13, then cover it with the pressure plate 22 and tighten it with the screw 23. After the shockproof component 2 is fixed, the outer wall of the surrounding edge 12 forms a complete plane, so that the outer wall of the surrounding edge 12 forms a beautiful and smooth effect.

[0050] In a typical embodiment of the present invention, Figure 5 、 6As shown, the elastic pad 21 includes an elastic pad body 211 and a pressure edge 212 extending along the periphery of the elastic pad body 211. A stop step 214 is formed at the connection between the elastic pad body 211 and the pressure edge 212. The stop step 214 is formed by the thickness of the elastic pad body 211 being greater than the thickness of the pressure edge 212. The stop step 214 can cooperate with the installation step 14 to limit the installation depth of the elastic pad 21 in the through groove 13, thereby controlling the exposed size of the elastic pad 221 in the inner cavity 18. Notches 215 are formed at the four corners of the pressure edge 212. The purpose of the notches 215 is to cooperate with the clearance function. The provision of the notches 215 here can facilitate the insertion of the screws 23 when fixing, and the notches 215 also play a role in making way for the protruding fixing platform 15.

[0051] This program, such as Figure 1 、 5 As shown, at least one ridge 213 is formed on the inner side wall of the elastic pad body 211. Preferably, the ridge 213 is set as a parallel structure of two or more, which can further enhance the shockproof effect of the elastic pad 21. When the dust cover 100 is installed, the ridge 213 will be squeezed and deformed with the outer wall of the connector plug interface 201, thereby firmly fixing the dust cover 100 on the connector plug interface 201, improving the shockproof effect of the dust cover 100, and increasing the friction between the dust cover 100 and the connector plug interface 201. At the same time, the ridge 213 provides an inward squeezing force for the connector plug interface 201 to improve the installation and fastening effect of the dust cover 100. By using a non-metallic elastic material, such as a rubber material, the elastic pad 21 can be used to avoid noise generated by vibration of the metal material, and at the same time avoid damage to the connector plug interface 201 caused by the metal material of the dust cover.

[0052] In this embodiment, Figure 5 、 6As shown in Figures 7 and 8, in order to improve the fixing effect of the elastic pad 21, a pressure plate 22 with the following structure is also provided. The outer shape structure of the pressure plate 22 in this solution matches the outer shape of the mounting step 14, so that the outer wall of the edge 12 of the cap 1 is formed into a flat outer shape structure. The pressure plate 22 of this solution is a plate-like structure with a rectangular rounded corner structure. A through hole 222 for the screw 23 to pass through is formed on the pressure plate 22. Specifically, the pressure plate 22 is fixed to the outer wall of the elastic pad 21 by pressing. The screw 23 passes through the through hole 222 into the threaded hole 16 and is screwed in to be fixed. In order to improve the anti-slip effect of the contact end surface of the elastic pad 21 and the pressure plate 22, an anti-slip groove 221 is formed on the inner end surface of the pressure plate 22. The number and size of the anti-slip grooves 221 can be set as needed. Preferably, the anti-slip grooves 221 can be set. It is arranged as one on each side as shown in the figure, and the two anti-slip grooves 221 are arranged parallel to each other. When the pressure plate 22 presses the elastic pad 21, the elastic pad 21 will be squeezed and deformed, so that the partially deformed extruded deformed part 216 enters the anti-slip groove 221 to enhance the anti-slip effect of the relative contact end face. Preferably, the length setting direction of the anti-slip groove 221 is perpendicular to the axial direction of the surrounding edge 12. Such a direction setting can increase the friction between the dust cover 100 and the connector plug interface 201, thereby enhancing the anti-falling effect.

[0053] In this scheme, if Figure 1 、 11 As shown, to further ensure the installation of the dust cover 100, a locking piece 3 is provided on the inner side wall of the rim 12 of the cap 1. The purpose of the locking piece 3 is to lock the dust cover 100 to the connector plug interface 201. The locking piece 3 includes a fixed end 32 and a spring end 33. The spring end 33 is a bent structure, forming a curved boss protruding toward the center of the inner cavity 18. The fixed end 32 is fixed to the groove 17 of the inner cavity side wall of the rim 12 of the cap 1 by a fastener 31. The fastener 31 can be a screw or bolt, or other fixing methods can be used, such as strong bonding. It is also possible to form the locking piece 3 and the cap 1 integrally. However, this structural method increases the difficulty of component processing compared to the above method. When the dust cover 100 is installed on the connector plug interface 201, the spring end 33 will snap into the locking groove 203 on the outer wall of the connector plug interface 201.

[0054] like Figure 1 、 2 As shown, the dust cover edge 12 in this embodiment is a rectangular rounded-corner structure, the through groove 13 is located on a set of opposite side walls of the edge 12, the shockproof component 2 is symmetrically arranged in the through groove 13 of the two side walls, and the locking plate 3 is located on another set of opposite side walls of the edge 12, and the locking plate 3 is symmetrically arranged in the groove 17 of the two side walls.

[0055] Example 2

[0056] like Figure 8 、 9 , 10, 11, the utility model also provides a connector using the above-mentioned dust cover, including a connector body 200 and the dust cover 100 in the above-mentioned embodiment. The front end of the connector body 200 has a connector plug interface 201 for plugging and mating with the adapter connector. The shape of the connector plug interface 201 is adapted to the dust cover 100. A locking groove 202 is formed on the socket side wall 203 of the connector plug interface 201. After the socket side wall 203 of the connector plug interface 201 is squeezed and fixed with the ridge 213 of the elastic pad 21, the locking piece 14 is buckled into the locking groove 202 of the dust cover 100. Figure 8 、 9 As shown, after the dust cover 100 is assembled with the corresponding connector plug interface 201, the ridge 213 on the elastic pad 21 inside the dust cover 100 is elastically compressed, which can prevent the dust cover from colliding with the connector and damaging the connector body 200 due to severe vibration; Figure 10 、 11 As shown, the spring end 33 of the locking piece 3 is elastically deformed during locking, and then the spring end 33 rebounds and snaps into the locking groove 202 of the connector body 200 to achieve locking and fixing.

[0057] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
