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 capable of realizing automatic packaging, comprising an elastic cavity, a conductive elastomer containing functional components, and mounting pins. 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 silicone buttons of the above-mentioned 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. At the same time, the PCB board route is mostly installed manually, with low work efficiency. It is not suitable for large-scale industrial automation installation and damaged functional components cannot be replaced individually, which limits the application and promotion prospects of silicone buttons. Summary of the invention

[0006] In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a key structure that can satisfy the simultaneous connection or disconnection of multiple functional components to meet the usage requirements in complex application scenarios, and is suitable for large-scale industrial automation packaging and can individually replace damaged functional components, as well as a connector therefor.

[0007] To solve the above technical problem, one of the technical solutions adopted by the present invention is a solderless replaceable functional component connector that can achieve automated packaging, including an elastic cavity, a conductive elastomer, and mounting pins. The elastic cavity has an upper cavity with an opening. There are at least two conductive elastomers each containing a functional component embedded in the elastic cavity. A heat dissipation ventilation duct is provided on the bottom surface of the elastic cavity. Conductive rubber bodies are provided on both end faces of the functional component. The input and output ends of the functional component are respectively connected to the conductive rubber bodies on the two end faces. One end face of the conductive elastomer extends downward beyond the bottom end of the elastic cavity, and the other end face extends upward beyond the bottom surface of the upper cavity. The mounting pins are provided at the four corners of the elastic cavity and extend in the direction opposite to the opening of the upper cavity. By squeezing the elastic cavity, the connection or disconnection function between the functional component and the key body and the PCB circuit track through the conductive rubber bodies provided at both ends of the functional component is finally realized.

[0008] To solve the above technical problem, another technical solution adopted by the present invention is a solderless replaceable functional component connector that can achieve automated packaging, including an elastic cavity, a conductive elastomer, and mounting pins. The elastic cavity has an upper cavity with an opening. The conductive elastomer is a geometric body provided with at least two functional components. The geometric body is embedded in the elastic cavity. The functional component is embedded in the geometric body. The two ends of the functional component are flush with the two end faces of the geometric body. Conductive rubber bodies are provided on both end faces of the functional component. The input and output ends of the functional component are respectively connected to the conductive rubber bodies on the two end faces. One end face of the conductive elastomer extends downward beyond the bottom end of the elastic cavity, and the other end face extends upward beyond the bottom surface of the upper cavity. The mounting pins are provided at the four corners of the elastic cavity and extend in the direction opposite to the opening of the upper cavity. By squeezing the elastic cavity, the connection or disconnection function between the functional component contained in the conductive elastomer and the key body and the PCB circuit track is realized.

[0009] In the above two solutions:

[0010] To enhance the heat dissipation of the end faces of the conductive elastomer, 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 opened to facilitate heat dissipation.

[0011] For the convenience of inserting and positioning the installation pin, the head of the installation pin is in a conical shape, and an axial positioning counterbore is provided at the tail.

[0012] 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.

[0013] To prevent the accidental connection of the conductive elastomer during pressing and ensure the correctness of the connection by pressing, 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.

[0014] 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 is suitable for large-scale industrial automation installation and solder-free, and can separately replace damaged functional components.

The conductive rubber body is pressed to eliminate welding, respectively realizing the connection between the key, the functional components contained in the conductive elastic body 2, and the PCB circuit board trace, as well as the connection between the functional components contained in adjacent conductive elastic bodies 2. When the key is released, the connection between the key, the functional components contained in the conductive elastic body 2, and the PCB circuit board trace is disconnected, and the connection between the functional components contained in adjacent conductive elastic bodies 2 is disconnected, ultimately realizing the connection or disconnection control between multiple functional components to meet the usage requirements in complex application scenarios. When the functional component in the conductive elastic body 2 is damaged, the damaged single functional component can be removed and replaced.

[0081] Compared with the prior art, the present invention can meet the simultaneous connection or disconnection of multiple functional components to meet the usage requirements in complex application scenarios, is suitable for large-scale industrial automation installation, is solder-free, and can separately replace damaged functional components.
