Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite contacts, specifically to a composite contact that is easy to recycle. Background Technology
[0002] Chinese utility model patent application number 202021800183.2 proposes a composite contact. To facilitate the separation of the composite sheet and the substrate for recycling and resource conservation, it includes a substrate and a composite sheet. The composite sheet is connected to the upper side of the substrate by at least two sets of fasteners. The fasteners include fastening pieces fixed to the top surface of the substrate. The composite sheet has through holes equal in number to the number of fasteners, each allowing a fastening piece to pass through. After passing through the through holes, the fastening pieces are bent to one side to form a bent portion. The side surface of the substrate has a number of sliding holes equal in number to the number of fasteners. The bottom surface of the composite sheet has a number of through holes equal in number to the number of sliding holes. The through holes are connected to the adjacent bent portions. When the composite sheet is connected to the substrate, the sliding holes and through holes are aligned.
[0003] However, the applicant found that it still had some shortcomings:
[0004] First, the rubber layer placed between the substrate and the composite sheet reduces the contact area between the substrate and the composite sheet, which will reduce the conductivity between the substrate and the composite sheet.
[0005] Second, it fixes the substrate and composite sheet through the bending part, but the bending part can also deform under the action of external force, which may cause the bending part to deform during use, resulting in loosening of the connection between the substrate and the composite sheet and affecting the conductivity.
[0006] Third, the composite sheet requires external tools for installation and removal, making it inconvenient to use;
[0007] Accordingly, this utility model proposes a composite contact that is easy to recycle to solve the above problems. Utility Model Content

By setting contact holes and conductive sheets, the contact area between the substrate and the composite sheet is increased, enhancing conductivity. At the same time, it ensures stable contact between the composite sheet and the substrate, and slight up-and-down movement does not affect the connection between the composite sheet and the substrate. The composite sheet and the substrate are quickly connected by a convex ring, a snap ring, and a rubber connecting ring, and can be installed and removed without tools.

[0023] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:
[0024] have Figures 1-3 As shown, this utility model discloses a composite contact that is easy to recycle, including a substrate 1. A spherical groove 14 is provided in the upper surface of the substrate 1. The bottom of the spherical groove 14 is connected to a contact hole 11 located inside the substrate 1. A conductive sheet 12 with bending properties is provided on the inner wall of the contact hole 11 and is integrally connected with the substrate 1. A composite sheet 2 is inserted between the conductive sheets 12, penetrating and abutting against the inner wall of the contact hole 11.
[0025] Furthermore, the composite sheet 2 is provided with a spherical protrusion 22, the protrusion 22 being adapted to the shape of the spherical groove 14 and the protrusion 22 being in contact with the spherical groove 14.
[0026] Furthermore, a rubber pad 4 is provided on the inner wall of the spherical groove 14, and the rubber pad 4 is located between the protrusion 22 and the spherical groove 14.
[0027] Furthermore, a snap ring 13 is also provided inside the contact hole 11.
[0028] Furthermore, the composite sheet 2 is provided with a protruding ring 21 that can be adapted to the snap ring 13.
[0029] Furthermore, the composite sheet 2 and the substrate 1 are provided with external threads (not shown) on their annular outer surfaces. The external threads are threaded to a rubber connecting ring 31 with internal threads. The rubber connecting ring 31 has a skeleton 3 inside. The rubber connecting ring 31 connects and fixes the composite sheet 2 and the substrate 1.
[0030] Specifically, during use, the composite sheet 2 is directly inserted into the connection hole 11. The composite sheet 2 contacts the inner wall of the connection hole 11 and achieves conductivity. At the same time, the conductive sheet 12 is pushed open by the composite sheet 2 and closely adheres to the composite sheet 2, ensuring stable contact and conductivity.
[0031] At the same time, the convex ring 21 is inserted into the snap ring 13 to limit the composite sheet to a certain extent;
[0032] Rotate the composite sheet 2 so that the external thread of the composite sheet 2 and the base 1 can be connected. Then screw the rubber connecting ring 31 into the outside of the composite sheet 2 and the base 1 to further strengthen the connection stability between the composite sheet 2 and the base 1.
[0033] Meanwhile, the presence of the rubber connecting ring 31 and the rubber pad 4 allows for a certain degree of mobility between the substrate 1 and the composite sheet 2, which helps to reduce impact during contact collisions.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the technical solutions of this utility model have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
