[0020] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figure 1 and Figure 2 As shown, the utility model relates to a conductive elastic connector, including a conductive elastomer 1 and a metal base 2, the metal base 2 includes a plate body 21 and a fastener 22, the fasteners 22 are provided on opposite sides of the plate body 21, the conductive elastomer 1 is pressed on the upper side of the plate body 21, the fasteners 22 located on opposite sides of the plate body 21 fasten the conductive elastomer 1 to the plate body 21, and at least one side of the plate body 21 extends outward from the bottom area of ​​the conductive elastomer 1.

[0023] In the utility model, by allowing at least one side of the plate body 21 to extend outward from the bottom area of ​​the conductive elastomer 1, when the conductive elastic connector cannot be welded by SMT, the portion of the plate body 21 extending out of the bottom area of ​​the conductive elastomer 1 can still maintain a high electrical connection reliability with the grounding area by metal welding; at the same time, no adhesive is required between the conductive elastomer 1 and the metal base 2, so the resistance is lower.

[0024] In this embodiment, the fastener 22 and the plate body 21 are integrally formed.

[0025] Specifically, the fastener 22 is integrally formed with the plate body 21, and the fastener 22 can be bent so that the conductive elastomer 1 can be firmly connected to the plate body 21. The fastener 22 and the plate body 21 can also be a split design, so that the fastener 22 can be fixed to the plate body 21 by welding or connecting with a fixing part.

[0026] In this embodiment, the metal base 2 is made of one of nickel sheet, stainless steel or nickel-plated copper alloy to have good corrosion resistance and ensure service life. Moreover, based on the plastic deformation or elastic deformation of the metal, the installation and removal of the conductive elastomer 1 and the metal base 2 are more convenient and simple.

[0027] Preferably, the thickness of the plate 21 and the fastener 22 is greater than or equal to 0.1 mm, so as to ensure the fastening force of the conductive elastomer 1 to ensure that the conductive elastomer 1 is firmly fixed on the metal base 2 .

[0028] In this embodiment, the conductive elastomer 1 includes an elastic member 11 and a conductive layer 12, the elastic member 11 has a first side surface 111 and a second side surface 112 opposite to each other in the width direction, and a third side surface 113 and a fourth side surface 114 opposite to each other in the thickness direction, the conductive layer 12 at least covers the first side surface 111, the second side surface 112 and the third side surface 113 of the elastic member 11, and the fourth side surface 114 of the conductive layer 12 faces the plate body 21, so that the conductive layer 12 outside the elastic member 11 is electrically connected with the metal base 2.

[0029] Preferably, a through hole 13 is opened in the middle area of ​​the elastic member 11 along the length direction, and the plate body 21 is provided with the fasteners 22 on both sides of the length direction. The fasteners 22 on both sides of the length direction of the plate body 21 extend into the two ends of the through hole 13 one by one and are embedded in the inner wall surface of the through hole 13, thereby stabilizing the conductive elastomer 1 on the metal base 2.

[0030] In this embodiment, the elastic member 11 is made of silicone rubber, so that the elastic member 11 has good high and low temperature resistance, aging resistance, and insulation performance, and has a longer service life, thereby reducing maintenance.

[0031] In this embodiment, the conductive layer 12 is a conductive coating or a conductive film.

[0032] Specifically, the conductive coating is a mixture of silicone rubber and conductive filler, the conductive filler is an existing conductive filler in the market, and the conductive filler is one or more of nickel carbon, silver-coated nickel, and silver-coated aluminum; the conductive film can be a tin-plated or gold-plated PI film, or a conductive cloth. Therefore, no matter the conductive layer 12 is a conductive coating or a conductive film, it can ensure electrical conduction with the metal base 2.

[0033] In summary, compared with the prior art, the conductive elastic connector of the present application can still maintain a high electrical connection reliability with the grounding area through metal welding in scenarios where SMT welding cannot be used, and the connection between the conductive elastomer and the metal base does not require adhesive, and the resistance is lower. In addition, the disassembly and assembly of the conductive elastomer and the metal base is more convenient and quick.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
