Description

Technical Field

[0001] The present invention relates to the technical field of polymer elastomer buttons, and in particular to a solder-free replaceable functional component connector, comprising an elastic cavity, a conductive elastomer containing functional components, and a hardware welding pin frame. Background Art

[0002] The conductive rubber key industry was born in the 1980s and 1990s. In order to solve the problem that traditional non-standard single silicone keys are not suitable for surface mounting technology, surface mount silicone keys were proposed, that is, a pin bracket is added to the silicone key base, and a set of silicone keys are formed by molding.

[0003] A Chinese utility model with authorization announcement number CN208157288U and invention name "A switch button with built-in replaceable functional components" discloses a switch button with built-in replaceable functional components. The switch button can realize the switching function by pressing the conductive half ring on the control button to offset the conductive layer structure of the functional part structure area below and to connect and disconnect the functional track open to the corresponding integral key circuit board below.

[0004] The Chinese utility model with authorization announcement number CN105655174B and invention name “A luminous patch-type elastic key” discloses a luminous patch-type elastic key, which includes a base and a key software, and the key software includes a key convex body, an elastic software and a conductive contact, and the conductive contact is arranged on the lower end surface of the key convex body. The conductive contact is annular, and a package of an LED chip is arranged in the middle of the annular conductive contact. The LED chip and the conductive contact are electrically interconnected through the package wiring. The conductive contact, the LED chip and the package are connected as a whole, and the on-off control of the luminous LED chip and the PCB board route function track thereunder is achieved by pressing the elastic key.

[0005] However, the above-mentioned silicone buttons in the prior art can only control the connection or disconnection of related functional tracks or single functions of components on the PCB board route. For some complex application scenarios that require the simultaneous application of multiple functional components, it is impossible to perform simultaneous connection or disconnection control and it is impossible to replace damaged functional components individually, which limits the application and promotion prospects of silicone buttons. Summary of the invention

[0006] In view of the deficiencies in the prior art, the technical problem solved by the present invention is to provide a key structure that can connect or disconnect multiple functional elements at the same time to meet the usage requirements in complex application scenarios and can replace damaged functional components individually.

[0007] To solve the above technical problems, one of the technical solutions adopted by the present invention is a solderless replaceable functional component connector, which includes an elastic cavity, a conductive elastomer, and a hardware welding pin frame. The elastic cavity has an upper cavity with an opening, and a heat dissipation ventilation channel is provided on the bottom surface of the elastic cavity. There are at least 3 conductive elastomers, and functional components are embedded in the elastic cavity. Conductive rubber bodies are provided on both end faces of the functional components. The input and output ends of the functional components are respectively connected to the conductive rubber bodies on the two end faces. One end face of the conductive elastomer extends downward from the bottom end of the elastic cavity, and the other end face extends upward from the bottom surface of the upper cavity. There is at least one hardware welding pin frame and it is embedded in the elastic cavity. By squeezing the elastic cavity, finally, the connection or disconnection function between the functional components and the key body and the PCB circuit board trace is realized through the conductive rubber bodies provided at both ends of the functional components.

[0008] To solve the above technical problems, another technical solution adopted by the present invention is a solderless replaceable functional component connector, which includes an elastic cavity, a conductive elastomer, and a hardware welding pin frame. The elastic cavity has an upper cavity with an opening, and a heat dissipation ventilation channel is provided on the bottom surface of the elastic cavity. The conductive elastomer is a geometric body provided with at least 2 functional components. The geometric body is embedded in the elastic cavity, and the functional components are embedded in the geometric body. The two ends of the functional components are flush with the two end faces of the geometric body. Conductive rubber bodies are provided on both end faces of the functional components. The input and output ends of the functional components are respectively connected to the conductive rubber bodies on the two end faces. One end face of the conductive elastomer extends downward from the bottom end of the elastic cavity, and the other end face extends upward from the bottom surface of the upper cavity. There is at least one hardware welding pin frame and it is embedded in the elastic cavity. By squeezing the elastic cavity, finally, the connection or disconnection function between the functional components and the key body and the PCB circuit board trace is realized through the conductive rubber bodies provided at both ends of the functional components.

[0009] In the above two solutions:

[0010] To enhance heat dissipation, as an improvement of the present invention, nano-particle layers are provided on the end faces of the conductive rubber bodies at both ends of the conductive elastomer, and ventilation grooves are provided to facilitate heat dissipation.

[0011] Preferably, the hardware welding pin frame has a pin end extending outside the elastic cavity.

[0012] Preferably, the number of the hardware welding pin frames is 2 and they are symmetrically distributed.

[0013] The elastic cavity has an upper cavity with an opening. The bottom surface of the upper cavity is provided with through holes corresponding to the number of the conductive elastomers. The inner diameter of the through holes is smaller than the outer diameter of the conductive elastomers so as to be installed by interference fit and inlay. The shape of the opening can be any geometric shape.

[0014] To prevent the accidental connection of the conductive elastomer when pressed and ensure the correctness of the connection when pressed, as an improvement of the present invention, an elastic inclined wall is provided at the lower end of the upper cavity to form a lower cavity with the bottom surface. One end of the conductive elastomer extends downward through the upper cavity to above the lower cavity, and the other end extends upward out of the bottom surface of the upper cavity.

[0015] Compared with the prior art, the present invention can satisfy the simultaneous connection or disconnection of multiple functional components to meet the usage requirements in complex application scenarios and can replace damaged functional components without soldering.
