DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-5 This application is described in further detail. Example 1
[0033] An embodiment of the present application discloses a dustproof terminal.
[0034] Reference Figure 1 A dustproof terminal block includes a male connector 1 and a female connector 2. Both the male connector 1 and the female connector 2 are connected with conductive wires (not shown in the figure). One end of the male connector 1 is fixedly connected with a plug 11. One end of the female connector 2 is provided with a socket 21. The socket 21 is used for matching the plug 11. The male connector 1 and the female connector 2 are electrically connected by plugging and matching the plug 11 and the socket 21 to achieve electrical connection between the conductive wires.
[0035] Reference Figure 1 , Figure 2 , transition strips 8 are installed on the two opposite side walls of the female connector 2, and the two transition strips 8 are symmetrically arranged on both sides of the socket 21. One side of the transition strip 8 is hinged to the side wall of the female connector 2. For the convenience of description, the side of the transition strip 8 away from the female connector 2 is defined as the free side of the transition strip 8 below.
[0036] Reference Figure 1 , Figure 2 The female head 2 is respectively connected with the first cover 3 and the second cover 4, which are correspondingly arranged on the two transition strips 8, one side of the first cover 3 is hinged to the free side of the corresponding transition strip 8, one side of the second cover 4 is hinged to the free side of the corresponding transition strip 8, and the first cover 3 and the second cover 4 are hinged to the side wall of the female head 2 through their respective corresponding transition strips 8; when the first cover 3 and the second cover 4 are both flipped toward one side of the socket 21, and when the plate surface of the first cover 3 and the plate surface of the second cover 4 are both in contact with the end surface of the female head 2 close to the male head 1, the first cover 3 and the second cover 4 jointly cover the socket 21 of the female head 2.
[0037] Reference Figure 2 , Figure 3 A connector 5 is installed between the first cover 3 and the second cover 4, and the first cover 3 and the second cover 4 are detachably connected through the connector 5. When the first cover 3 and the second cover 4 are connected to each other through the connector 5, the first cover 3 and the second cover 4 jointly cover the jack 21 (that is, the plate surface of the first cover 3 and the plate surface of the second cover 4 are both in contact with the end surface of the female connector 2 close to the male connector 1).
[0038] Reference Figure 3 In this embodiment, the connecting member 5 includes a first magnet 51 and a second magnet 52. The first magnet 51 is embedded in the first cover 3, and the second magnet 52 is embedded in the second cover 4. When the first cover 3 and the second cover 4 jointly cover the socket 21, the first magnet 51 and the second magnet 52 are magnetically attracted to each other and there is a magnetic attraction force.
[0039] Reference Figure 1 , Figure 2 The plate surfaces of the first cover 3 and the second cover 4 are fixedly mounted with clamping strips 6, and the clamping strips 6 are cylindrical long strips; the side walls of the female head 2 are mounted with clamping members, and there are two groups of clamping members, which are symmetrically arranged on the two opposite side walls of the female head 2, and the two groups of clamping members are arranged corresponding to the two clamping strips 6; the clamping members are used to buckle with the clamping strips 6 of the first cover 3 or the clamping strips 6 of the second cover 4. When the first cover 3 and the second cover 4 are in the open state, the clamping strips 6 of the first cover 3 and the clamping strips 6 of the second cover 4 are both limited to the side walls of the female head 2 by the corresponding clamping members, so that the first cover 3 and the second cover 4 are respectively limited to the two opposite side walls of the female head 2.
[0040] Reference Figure 2 , Figure 4 In this embodiment, the clamping member is configured as a clamping ring 7, which is fixedly connected to the side wall of the female head 2, and is elastically configured. The clamping ring 7 is provided with an inlet and outlet 71 for the clamping strip 6 to enter and exit; a guide block 72 is fixedly installed on the side wall of the clamping ring 7 located at the inlet and outlet 71, and the guide block 72 has a guide surface 73, and the guide surface 73 is used for the clamping strip 6 to abut against, so as to force the clamping ring 7 to deform and expand the inlet and outlet 71.
[0041] The implementation principle of Example 1 of the present application is: when not in use (the male head 1 and the female head 2 are separated from each other), the first cover 3 and the second cover 4 are flipped over respectively, so that the plate surface of the first cover 3 and the plate surface of the second cover 4 are attached to the end surface of the female head 2 close to the male head 1. At this time, the first magnet 51 and the second magnet 52 are magnetically attracted to each other, thereby limiting each other, so that the first cover 3 and the second cover 4 can jointly cover the socket 21 of the female head 2, reducing the possibility of foreign matter falling into the socket 21, and thereby reducing the possibility of the socket 21 of the female head 2 being contaminated.
[0042] When in use, the two clamping strips 6 are pulled to force the first cover 3 and the second cover 4 to separate from each other, and then the first cover 3 and the second cover 4 are turned over, and the clamping strips 6 of the first cover 3 are buckled into the corresponding clamping rings 7, and the clamping strips 6 of the second cover 4 are buckled into the corresponding clamping rings 7. The clamping rings 7 can fix the first cover 3 and the second cover 4, so that the socket 21 of the female head 2 remains in an open state to facilitate the connection between the female head 2 and the male head 1. Example 2
[0043] An embodiment of the present application discloses a dustproof terminal.
[0044] Reference Figure 5 The difference between the dustproof terminal disclosed in the embodiment of the present application and the embodiment 1 is that:
[0045] In this embodiment, a sliding groove 22 is provided on the inner wall of the socket 21, and a contact strip 23 is slidably installed in the sliding groove 22. A contact sheet 24 is fixedly installed on the side wall of the socket 21 of the contact strip 23, and the contact sheet 24 is a rubber sheet; a sliding member 9 is installed on the contact strip 23. When the first cover 3 is limited to the side wall of the female head 2 (that is, when the clamping strip 6 of the first cover 3 is buckled in the clamping ring 7), the sliding member 9 drives the contact strip 23 to move toward the side close to the socket 21, so that the contact sheet 24 is tightly pressed against the plug 11 of the male head 1, and the contact strip 23 is pressed against the plug 11 of the male head 1 through the contact sheet 24.
[0046] Reference Figure 5 The sliding member 9 includes a sliding rod 91 and a return spring 92. One end of the sliding rod 91 is fixedly connected to the abutment strip 23, and the other end passes through the side wall of the female head 2; the return spring 92 is installed between the abutment strip 23 and the sliding groove 22. One end of the return spring 92 is fixedly connected to the abutment strip 23, and the other end is fixedly connected to the inner wall of the sliding groove 22. The return spring 92 normally causes the abutment strip 23 and the abutment sheet 24 to move into the sliding groove 22; when the first cover 3 is limited to the side wall of the female head 2, the first cover 3 pushes the abutment strip 23 through the sliding rod 91, and causes the abutment strip 23 to press against the male head 1.
[0047] The implementation principle of Example 2 of the present application is: open the first cover 3, and buckle the clamping strip 6 of the first cover 3 to the clamping ring 7 to fix the first cover 3. During the process of buckling the clamping strip 6 of the first cover 3 to the clamping ring 7, the first cover 3 can push the abutment strip 23 through the sliding rod 91, forcing the abutment strip 23 to move toward the side close to the socket 21, so that the abutment sheet 24 of the abutment strip 23 can be tightly pressed against the plug 11 of the male head 1, thereby improving the connection stability between the male head 1 and the female head 2.
[0048] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
