Patent No. CN201720608185.3 proposes a button connector that can prevent buttons or messy wire pins from falling off from the mounting hole. Patent No. CN202221421655.2 discloses a high-temperature resistant RF coaxial connector that can only transmit microwave signals between boards. CN202210678306.7 discloses a button-flexible cable assembly that uses solder-free and low-profile interconnection between buttons and rigid-flexible board assemblies to achieve signal interconnection between devices. It has the advantages of small size, anti-misinsertion and blind assembly.

[0003] Although the button connector in the above invention has the characteristics of solder-free, low profile and high density, and solves the problem of vertical interconnection between boards, it does not solve the problem of circuit control, that is, it has a switch-like function that requires connection in the initial state and disconnection in the pressed state, and cannot meet the signal transmission requirements in specific occasions.

[0016] The present invention provides a hair button connector with a switch function. When the elastic end and the fixed end are not connected, the step portion in the protective cap contacts the conductive sheet due to the elastic force of the hair button, and the signal passes through the first wire, the first pin, the hair button, and the conductive sheet in sequence to achieve a short-circuit effect on the signal, thereby achieving a signal connection function when the elastic end and the fixed end are not connected (i.e., in an initial state); when the elastic end and the fixed end are connected, the connecting portion in the protective cap is pressed by the end face of the second pin, and the protective cap is pressed into the inner cavity of the first base as a whole. At this time, the elastic end is in a compressed state, the step portion and the conductive sheet are separated, and the signal passes through the first wire, the first pin, the hair button, the step portion, the connecting portion, the second pin, and the second wire in sequence, thereby achieving a switch-like function that the elastic end and the fixed end need to be disconnected from the conductive sheet and connected to the elastic end when the elastic end and the fixed end are connected (i.e., in a pressed state). This switch function can meet the signal transmission requirements in specific occasions; and it has the characteristics of solder-free, low profile and high density, thereby improving the level of structural and functional integration.

[0028] like Figure 2 , Figure 5 As shown, Figure 2 The figure shows a schematic diagram of the three-dimensional structure of the elastic end 10 in a fur button connector with a switch function in an embodiment; Figure 5 Shown is a schematic diagram of the internal structure of the elastic end 10 in a wool button connector with a switch function in different connection states in an embodiment.

[0029] The elastic end 10 includes a first base 11, a wool button 16 is arranged in the middle of the inner cavity of the first base 11, a protective cap 13 and a conductive sheet 15 are arranged in sequence on the end of the wool button 16 close to the docking side, the protective cap 13 includes a docking portion 131 and a step portion 132, and a through hole 151 adapted to the docking portion 131 is opened on the conductive sheet 15; the elastic end 10 also includes a first wire 12 and a first plug pin 17, and the first plug pin 17 is in contact with the end of the wool button 16 away from the step portion 132;

[0030] The fur button 16 is an elastic body with a certain outer size and manufactured according to a certain process, one end of which contacts the end surface of the conductive sheet 15 in state 1 (i.e. the elastic end 10 and the fixed end 20 are not yet connected), and the other end contacts the end surface of the first pin 17;

[0031] The inner cavity of the first base 11 is provided with corresponding step holes for installing the conductive sheet 15, the protective cap 13, the wool button 16, and the first pin 17;

[0032] like Figure 4 As shown, Figure 4 The figure shows a three-dimensional structure diagram of a protective cap 13 and a conductive sheet 15 in a button connector with a switch function in an embodiment;

[0033] The protective cap 13 is a rotating body with steps, wherein the step rotating body is the step portion 132, and the head end rotating body is the docking portion 131, which is installed in the inner cavity of the first base 11 and is respectively matched with the step hole gap in the inner cavity of the first base 11; the conductive sheet 15 is a conductive thin sheet, and a through hole 151 and a countersunk hole 152 are opened on the surface, wherein the countersunk hole 152 is riveted and fixed to the first base 11 by rivets, and the aperture of the through hole 151 is larger than the diameter of the docking portion 131 and smaller than the diameter of the step portion 132, and the through hole 151 and the docking portion 131 are located on the same axis.

[0034] like Figure 3 , Figure 6 As shown, Figure 3 The figure shows a three-dimensional structure diagram of a fixed end 20 in a fur button connector with a switch function in an embodiment. Figure 6 What is shown is a schematic diagram of the internal structure of the fixed end 20 in a hair button connector with a switch function in an embodiment.

[0035] It includes a fixed end 20, which includes a second base 21. The inner cavity of the second base 21 is interference-fitted with a second pin 22, and one end of the second pin 22 extends out of the docking side of the second base 21; the tail ends of the first pin 17 and the second pin 22 are both provided with welding grooves, and the first pin 17 and the second pin 22 are respectively welded and fixed to the first wire 12 and the second wire 23 through the welding grooves.

[0037] The present invention provides a button connector with a switch function. When the elastic end 10 and the fixed end 20 are not connected, Figure 5 In the first state, under the elastic force of the hair button 16, the step portion 132 in the protective cap 13 contacts the conductive sheet 15, and the signal passes through the first wire 12, the first pin 17, the hair button 16, and the conductive sheet 15 in sequence, so as to achieve the short-circuit effect of the signal, thereby achieving the function of signal connection when the elastic end 10 and the fixed end 20 are not connected (i.e., in the initial state); when the elastic end 10 and the fixed end 20 are connected, at this time, as shown in FIG.

At this time, the elastic end is in a compressed state, the step portion 132 and the conductive sheet 15 are separated, and the signal passes through the first wire 12, the first pin 17, the wool button 16, the step portion 132, the docking portion 131, the second pin 22, and the second wire 23 in sequence, thereby realizing a switch-like function that the elastic end 10 and the fixed end 20 need to be disconnected from the conductive sheet 15 and connected to the fixed end 20 when the elastic end 10 and the fixed end 20 are docked (i.e. in the pressed state). This switch function can meet the signal transmission requirements in specific occasions; and it has the characteristics of solder-free, low profile and high density, thereby improving the level of structural and functional integration.
