[0037] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Those skilled in the art will appreciate that, unless otherwise defined, all terms used herein (including technical terms and scientific terms) have the same meaning as the general understanding of those skilled in the art to which the present invention pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted in an idealized or overly formal sense unless specifically defined as herein. Those skilled in the art will appreciate that, unless specifically stated, the singular forms "a", "an", "the" and "the" used herein may also include plural forms.

[0039] Combine Figures 1 to 9As shown, an embodiment of the present invention provides a sensor connection device 100 suitable for double-sided electric shock, and the upper and lower surfaces of the electrical connection part 200a of the sensor 200 are provided with electrical contact points 210, including: a middle frame 110, a lower spring pin linkage plate 150, an upper spring pin assembly 120, a lower spring pin assembly 130, a cam assembly and a toggle rod 180.

[0040] Specifically, the middle frame 110 serves as the support and mounting carrier for the entire connection device. A support assembly 114 is circumferentially arranged inside the middle frame. A hollow portion 115 is defined in the center of the support assembly 114, providing contact with the sensor and allowing for the installation of the connector. A sensor guide plate 140 is positioned on the lower surface of the support assembly 114 to provide guidance for the loading of the sensor 200, thereby improving the connection efficiency between the sensor connection device 100 and the sensor 200.

[0041] The lower spring pin linkage plate 150 and the upper spring pin assembly 120 are disposed above the support assembly 114. The upper spring pin assembly 120 is used to electrically connect to the electrical contact point 210 on the upper surface of the sensor 200. The lower spring pin linkage plate 150 is used to drive the lower spring pin assembly 130 upward to achieve electrical connection with the electrical contact point 210 on the lower surface of the sensor 100. The lower spring pin assembly 130 is disposed below the sensor guide limit plate 140. The lower spring pin assembly 130, the upper spring pin assembly 120, and the lower spring pin linkage plate 150 are connected by a linkage rod 160 and an elastic assembly 170. The linkage rod 160 passes through the hollow portion 115. The upper spring pin assembly 120 and the lower spring pin assembly 130 are respectively electrically connected to the wiring head 193 via the double-sided connecting seat 190. The wiring head 193 is connected to the equipment through a dedicated structure for electrical signal connection.

[0042] The toggle lever 180 is rotatably connected to the middle frame 110 via a rotating shaft, and the cam assembly is disposed on the rotating shaft, thereby driving the cam assembly located between the lower pin linkage plate 150 and the upper pin assembly 120 to rotate. When the long side of the cam assembly is located between the lower pin linkage plate 150 and the upper pin assembly 120, the upper pin assembly 120 and the lower pin assembly 130 are in a clamped state, thereby clamping the sensor 200 and respectively making electrical contact with the electrical contact points 210 on the corresponding sides. It is understood that when the short side of the cam assembly is located in the gap between the lower pin linkage plate 150 and the upper pin assembly 120 (or when the long side of the cam assembly is in a horizontal state), the upper pin assembly 120 and the lower pin assembly 130 are in a separated state. At this time, the sensor 200 can be loaded along the sensor guide limit plate 140 or the sensor 200 can be pulled out along the sensor guide limit plate 140.

[0043] The sensor connection device 100 provided in this embodiment drives the movement of the upper and lower spring pin assemblies 130 through a cam assembly, thereby achieving one-to-one contact between the spring pins and the electrical contact points 210 on the sensor, thereby solving the problems of difficulty in connecting multiple points of the sensor and limited reusability. The upper and lower spring pin assemblies 130 and the sensor guide limit plate 140 ensure connection strength and loading convenience. At the same time, the spring pin connection narrows the width of the connection part of the entire sensor, which is conducive to the miniaturization design of the sensor and connector.

[0044] In some embodiments, as Figure 8 As shown, the upper ejection pin assembly 120 includes an upper ejection pin circuit board 123 , an upper ejection pin holder 125 , two upper ejection pin circuit board fixing blocks 122 and an upper ejection pin circuit board fixing screw 126 .

[0045] Specifically, a plurality of mounting holes are provided around the pair of upper pin retaining frames 125, and two upper pin circuit board fixing blocks 122 are located on both sides of the upper surface of the upper pin circuit board 123 along the loading direction of the sensor 200. Corresponding threaded holes are provided on the upper pin circuit board fixing blocks 122, and the corresponding mounting holes and threaded holes are fixed by upper pin circuit board fixing screws 126 to fix the upper pin circuit board 123 to the upper pin retaining frame 125.

[0046] The upper spring pin holder 125 includes a plurality of upper spring pin 124 holes, each of which is provided with an upper spring pin 124. The upper end of the upper spring pin 124 is in electrical contact with the upper spring pin circuit board 123, and the lower end of the upper spring pin 124 is used to make electrical contact with the electrical contact point 210 on the upper surface of the sensor 200.

[0047] Alternatively, as Figure 7 As shown, the cam assembly includes two symmetrically arranged cam structures; the two cam structures rotate synchronously under the drive of the toggle lever 180. The cam structures are located between the corresponding upper ejection pin circuit board fixing block 122 and the lower ejection pin linkage plate 150. When the upper ejection pin assembly 120 and the lower ejection pin assembly 130 are in the clamped state, the long sides of the cam structures press between the lower ejection pin linkage plate 150 and the upper ejection pin circuit board fixing block 122.

[0048] In this embodiment, by providing two spaced cam structures, the forces on the upper and lower spring pin assemblies 130 can be more evenly distributed, which is beneficial to improving the contact stability between the spring pin and the sensor electrical contact point 210, thereby improving the connection stability of the entire connection device.

[0049] In some embodiments, as Figure 9 As shown, the lower ejection pin assembly 130 includes: a lower ejection pin circuit board 133 , a lower ejection pin retainer 135 , two lower ejection pin circuit board fixing blocks 132 and a lower ejection pin circuit board fixing screw 136 .

Corresponding threaded holes are provided on the lower pin circuit board fixing blocks 132, and the corresponding mounting holes and threaded holes are fixed by the lower pin circuit board fixing screws 136 to fix the lower pin circuit board 133 to the lower pin retainer 135.

[0051] The lower spring pin holder 135 includes a plurality of lower spring pin 134 holes, each of which is provided with a lower spring pin 134. The lower end of the lower spring pin 134 is in electrical contact with the lower spring pin circuit board 133, and the upper end of the lower spring pin 134 is used to make electrical contact with the electrical contact point 210 on the lower surface of the sensor 200.

[0052] In some embodiments, continue to refer to Figure 2 and Figure 9 The lower spring pin assembly 130 also includes: a sensor limit pin 137; there are two sensor limit pins 137, which are respectively located on both sides of the lower spring pin holder 135, and arc-shaped positioning grooves 220 are provided at corresponding positions on both sides of the sensor 200. When the connector is in a predetermined position and is clamped, the sensor limit pins 137 are respectively snapped into the corresponding arc-shaped positioning grooves 220, thereby limiting the sensor 200 and improving the connection stability of the sensor 200 and the sensor connection device 100.

[0053] In some embodiments, as Figure 6 As shown, a limit portion is provided at the lower end of the linkage rod 160 , and the linkage rod 160 passes through the lower spring needle holder 135 , the sensor guide limit plate 140 and the upper spring needle holder 125 from bottom to top.

[0055] In some embodiments, as Figures 3 to 6As shown, the middle frame 110 is provided with side panels on both sides along the sensor loading direction, and a mounting plate 116 is provided between the two side panels. The mounting plate 116 is used to fix the double-sided connecting base 190. The mounting plate 116 and the support assembly 114 are both arranged on the inner side of the middle frame 110, wherein the mounting plate 116 is close to the terminal head 193, and the support assembly 114 is close to the sensor.

[0056] The double-sided connecting seat 190 includes an upper connecting seat 191 and a lower connecting seat 192. The upper connecting seat 191 is electrically connected to the upper spring pin assembly 120 through the first FPC 121, and the lower connecting seat 192 is electrically connected to the lower spring pin assembly 130 through the second FPC 131; the upper connecting seat 191 and the lower connecting seat 192 are respectively electrically connected to the connecting wires in the terminal head 193.

[0057] In some embodiments, as Figures 3 to 6 As shown, a mounting groove 111 is provided at one end of the middle frame 110 away from the sensor. The mounting groove 111 is used to cooperate with the wiring head 193 for installation so that the wiring head 193 is stuck in the middle frame 110. This is both beautiful and can provide certain protection for the wiring head 193.
