Description

[0002] In the existing water pump driver, the driver needs to receive external signal input to control the water pump motor. The signal plugging device of the driver is connected to the driver and the connector. The signal plugging device receives the input of the connector signal and completes the output of the driver signal.

[0003] In the prior art, the signal plugging device is injection molded. When injecting the insulating seat, the pin is injected and fixed to the insulating seat.

On the other hand, it will cause the water pump to short-circuit. In addition, the existing signal plugging device is injection molded. After the pins are inserted and pulled out multiple times, the pins are deformed and the pin fit becomes loose.

[0050] This embodiment provides a signal plugging device for electrically plugging with other structures.

[0051] As Figures 1-10 shown, the signal plugging device provided in this embodiment includes an insulating base 1 and a pin 2. The insulating base 1 is provided with a jack 11, and the jack 11 penetrates through the insulating base 1 along the insertion direction. The jack 11 includes a first section 111 and a second section 112, and a step surface 113 is formed between the first section 111 and the second section 112. The insulating base 1 is further provided with a limiting hole 12, and the limiting hole 12 is located on one side of the jack 11 and communicates with the jack 11. Specifically, the limiting hole 12 is located on one side in the length direction of the jack 11.

[0052] The pin 2 includes a body 21 and a first elastic piece 22. The first root 222 of the first elastic piece 22 is connected to the body 21, and there is a distance between the first free end 221 of the first elastic piece 22 and the body 21. That is, the first elastic piece 22 is inclined gradually away from the body 21 from the side where the first root 222 is located to the side where the first free end 221 of the first elastic piece 22 is located. The first elastic piece 22 has elasticity to enable the first free end 221 to approach or move away from the body 21. Specifically, the first elastic piece 22 is located on the side part of the body 21.

[0053] The pin 2 can be inserted into the jack 11, one end of the pin 2 can abut against the step surface 113, and the step surface 113 can limit the pin 2 from disengaging from the jack 11 along the insertion direction; the first elastic piece 22 can be located in the limiting hole 12, and the limiting hole 12 can limit the pin 2 from disengaging from the jack 11 along the direction opposite to the insertion direction.

[0054] When manufacturing the signal plugging device, the pin 2 and the insulating base 1 are processed separately. After the pin 2 and the insulating base 1 are processed, the pin 2 is assembled into the insulating base 1. Specifically, the pin 2 is inserted into the jack 11 from one end of the jack 11 (for example, the end of the first section 111 away from the second section 112). When the first elastic piece 22 enters the jack 11, under the extrusion of the jack 11, the first elastic piece 22 is elastically deformed by the extrusion of the jack 11, that is, the free end of the first elastic piece 22 moves toward the side close to the body 21, that is, the inclination angle of the first elastic piece 22 decreases, and the root of the first elastic piece 22 is elastically deformed and moves closer to the side where the body 21 is located, and the pin 2 can be smoothly inserted into the jack 11. When the pin 2 is plugged in place, one end of the pin 2 abuts against the step surface 113 (as Figure 3 shown), and the step surface 113 can limit the pin 2 from disengaging from the jack 11 along the insertion direction. When the pin 2 is plugged in place, the first elastic piece 22 returns to its deformed state, and the first elastic piece 22 is located in the limiting hole 12, and the limiting hole 12 can limit the pin 2 from disengaging from the jack 11 along the direction opposite to the insertion direction.

[0055] Optionally, the first free end 221 and the first root 222 are arranged along the insertion direction of the pin 2. When the pin 2 has a tendency to disengage from the jack 11 along the direction opposite to the insertion direction, the free end of the first elastic piece 22 can abut against the upper wall of the limiting hole 12 (the upper wall is named according to the Figure 3 shown direction and does not limit the structure of the limiting hole 12), so as to limit the further movement of the pin 2.

[0056] As Figure 2 shown, optionally, the number of jacks 11 is multiple, and the pins 2 and the jacks 11 are arranged in one-to-one correspondence. However, the number of jacks 11 is not limited to multiple, and can also be one or two.

[0057] As Figure 1 and Figure 7 shown, optionally, the limiting hole 12 is a square hole. The structure of the limiting hole 12 is not limited to this, as long as when the pin 2 has a tendency to disengage from the jack 11 along the direction opposite to the insertion direction, the limiting hole 12 can limit the first elastic piece 22 from disengaging from the limiting hole 12.

[0058] It can be understood that the limiting hole 12 penetrates one side of the insulating base 1. When the pin 2 needs to be replaced, the first free end 221 of the first elastic piece 22 can be pushed toward the side where the body 21 is located, so that the inclination angle of the first elastic piece 22 decreases. After the first elastic piece 22 completely enters the jack 11, the pin 2 is pulled out along the direction opposite to the insertion direction, and the pin 2 can be disengaged from the jack 11.

[0059] As Figures 3-5As shown, optionally, an avoidance notch 215 is formed in the body 21, and the avoidance notch 215 can avoid the first elastic piece 22. Thus, the first free end 221 of the first elastic piece 22 moves towards the side where the body 21 is located, enabling the pin 2 to slide within the jack 11.

[0060] As Figure 2 shown, the pin 2 has a hollow structure, and the to-be-connected component 10 can pass through the jack 11 and be inserted into the pin 2 to be electrically connected to the pin 2.

[0061] As Figures 3-6 shown, optionally, the body 21 includes a first wall 211, a second wall 212, a third wall 213, and a fourth wall 214 that are sequentially connected and enclose a square ring. Optionally, the first elastic piece 22 can be connected to the fourth wall 214, and the first elastic piece 22 can be integrally formed with the fourth wall 214. For example, a continuous curve or broken line can be cut or stamped on the fourth wall 214, and then the part enclosed by the curve or broken line is bent away from the body 21 to form the first elastic piece 22 in this embodiment. Part of the material can be cut off on the first wall 211 and the second wall 212 so that there is a certain space between the first elastic piece 22 and the first wall 211 and the second wall 212, and the cut-off material can form the avoidance notch 215.

[0062] As Figure 2 、 Figure 3 and Figures 8-10 shown, the body 21 is inserted into the first section 111, and the to-be-connected component 10 passes through the second section 112 and is inserted into the pin 2. The second section 112 can allow the to-be-connected component 10 to be inserted into the pin 2, and can also form a stepped surface 113 with the first section 111 to limit the movement of the pin 2. Optionally, the cross-sectional area of the second section 112 is smaller than the cross-sectional area of the first section 111 to form a stepped surface 113 between the first section 111 and the second section 112.

[0063] As Figure 8 and Figure 9 shown, the cross-sectional area of the second section 112 gradually increases from the end towards the side close to the first section 111, thus facilitating the insertion of the to-be-connected component 10.

[0064] As Figures 1-4 shown, optionally, the signal plugging device can further include a plug 24. The plug 24 is connected to the body 21 and extends out of the jack 11. The plug 24 can be inserted into the jack of another to-be-connected component to achieve electrical connection with another to-be-connected component.

[0065] In this embodiment, in order to solve the problem that the clamping and matching strength between the connector and the pin 2 is low, which easily leads to poor connection, the structure of the pin 2 is further improved. The pin 2 further includes an elastic clamping component 23, and the elastic clamping component 23 is connected to the body 21 and can clamp the connector to be connected 10. By clamping the connector to be connected 10 with the elastic clamping component 23, the matching strength between it and the pin 2 is improved, and the problem of poor connection is avoided.

[0066] As Figure 2 , Figure 4 and Figure 6 shown, optionally, the elastic clamping component 23 is located in the hollow structure of the pin 2, so that while clamping the connector to be connected 10, the structure of the pin 2 can be made compact.

[0067] Exemplarily, the elastic clamping component 23 includes a second elastic piece 231 and a third elastic piece 232 which are oppositely arranged, and the connector to be connected 10 can be clamped between the second elastic piece 231 and the third elastic piece 232. The second elastic piece 231 and the third elastic piece 232 have elasticity, and the minimum distance between the second elastic piece 231 and the third elastic piece 232 can be smaller than the size of the connector to be connected 10. During the insertion process of the connector to be connected 10, the distance between the second elastic piece 231 and the third elastic piece 232 increases. After the connector to be connected 10 is inserted, the connector to be connected 10 is clamped by the restoring force of the second elastic piece 231 and the third elastic piece 232.

[0068] As Figure 2 and Figure 6 shown, both the second elastic piece 231 and the third elastic piece 232 have a second root 2322 and a second free end 2321, and the second root 2322 is connected to the body 21. From the second root 2322 to the side where the second free end 2321 is located (optionally, the second free end 2321 and the second root 2322 are arranged along the insertion direction), the distance between the second elastic piece 231 and the third elastic piece 232 first gradually decreases and then gradually increases. The position where the distance between the second elastic piece 231 and the third elastic piece 232 is the smallest is where the connector to be connected 10 applies the clamping force.

[0069] The structure of the second elastic piece 231 and the third elastic piece 232 can make it easy for the connector to be connected 10 to be inserted between the second elastic piece 231 and the third elastic piece 232. At the same time, since the position where the distance between the second elastic piece 231 and the third elastic piece 232 is the smallest is located in the middle of the second elastic piece 231 and the third elastic piece 232, when the connector to be connected 10 is pulled out, the connector to be connected 10 will not rub against the second free ends 2321 of the second elastic piece 231 and the third elastic piece 232, avoiding wear of the connector to be connected 10, the second elastic piece 231 and the third elastic piece 232.

[0070] Optionally, the second elastic piece 231 and the third elastic piece 232 can be symmetrically arranged. Exemplarily, both the second elastic piece 231 and the third elastic piece 232 include a first inclined section 2323, an arc transition section 2324, and a second inclined section 2325. One end of the first inclined section 2323 away from the arc transition section 2324 is a second root 2322, and one end of the second inclined section 2325 away from the arc transition section 2324 is a second free end 2321. From the second root 2322 towards the side where the second free end 2321 is located (furthermore, in the direction opposite to the insertion direction), the two first inclined sections 2323 are inclined towards each other, and the two second inclined sections 2325 are inclined away from each other. The first inclined section 2323 and the second inclined section 2325 can cause the distance between the second elastic piece 231 and the third elastic piece 232 to gradually decrease first and then gradually increase.

[0071] The distance between the two arc transition sections 2324 is the smallest. The arc transition section 2324 applies a clamping force to the connector to be inserted 10. The arc transition section 2324 is an arc structure, and can be smoothly inserted into and pulled out from the connector to be inserted 10. At the same time, the arc transition section 2324 is in surface contact with the connector to be inserted 10, increasing the cooperation strength with the connector to be inserted 10.

[0072] As Figures 3-6 shown, optionally, a first opening 2111 is provided on the first wall 211, and a second opening 2131 is provided on the third wall 213. The second elastic piece 231 is aligned with the first opening 2111, and the second elastic piece 231 is aligned with the second opening 2131.

[0073] Optionally, the second elastic piece 231 and the third elastic piece 232 can be integrally formed with the body 21. Optionally, a continuous curve or broken line can be cut or stamped on the first wall 211 and the third wall 213, and then the part surrounded by the curve or broken line is bent by stamping to form the second elastic piece 231 and the third elastic piece 232 in this embodiment.

[0074] Optionally, the insulating base 1 is formed by injection molding, and the pin 2 can be formed by stamping. Stamping is convenient for processing pins 2 with special shapes, so as to realize the stable installation of the pin 2 in the jack 11 and improve the connection strength between the pin 2 and the connector to be inserted 10.

[0075] The signal plugging device provided in this embodiment is more reliable and effectively prevents the pins 2 from short-circuiting. The pins 2 can individually achieve special-shaped structures, are not affected by the injection molding process, and increase the cooperation strength between the signal plugging device and the connector to be inserted 10. The signal plugging device provided in this embodiment can improve the product reliability, reduce the quality risks brought by the existing signal plugging devices; can improve the production qualification rate of the signal plugging device and reduce the production cost.

[0076] Although the present utility model has been described in detail above with general descriptions, specific embodiments and experiments, modifications or improvements can be made to it based on the present utility model, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
