Description

Technical Field

[0001] The utility model is applied to the field of battery protection board testing, and particularly relates to a needle block structure with a pre-pressing function. Background Art

[0002] With the rapid development and emergence of batteries in electronic products, the design types of battery protection boards are becoming more and more, and various cables with connectors are becoming more and more complicated. An important part of battery protection board testing is to allow the connector of the battery protection board to press and communicate with the probe module. Therefore, how to fix the soft cable of the battery protection board in advance is very important. At present, it is usually necessary to pre-press and fix the cable with a pre-pressing block manually, but this method requires additional manual action, which is inconvenient for operation in locations with relatively narrow space. Based on the above problems, if a needle block structure that can pre-press the cable can be designed, by pre-pressing the product cable in advance, the probe module can automatically fix the cable before pressing the product connector, thereby reducing the damage to the cable caused by the free swing of the cable. At the same time, the needle block structure with a simple structure, smooth movement, and easy control can reduce manual operation and can be easily automated, which can solve the above problems well. Utility Model Content

At the same time, the needle block module and the pre-stressed block are both floating matched, which can absorb part of the impact force during the contact process to protect the product connector and the needle block module.

[0014] like Figures 1 to 2 As shown, in this embodiment, the utility model includes a needle block mounting plate 1, a needle block module 2 and a pre-pressing block 3, and an integrally formed pre-pressing fixed end 10 is provided on both sides of the needle block mounting plate 1, and the pre-pressing block 3 is provided on the pre-pressing fixed end 10, and the pre-pressing block 3 is floatingly matched with the pre-pressing fixed end 10, and the needle block module 2 is provided on the needle block mounting plate 1, and the needle block module 2 is floatingly matched with the needle block mounting plate 1. It can be seen that the pre-stressing fixed end 10 is provided on the needle block mounting plate 1, the pre-stressing block 3 is floatingly matched with the pre-stressing fixed end 10, the needle block module 2 is floatingly matched with the needle block mounting plate 1, and the pre-stressing block 3 is set at a height higher than the needle block module 2. The needle block mounting plate 1 is limited by the external device. Therefore, when the needle block mounting plate 1 is driven by the external device to move toward the battery protection board, the pre-stressing block 3 first cooperates with the product cable limit, and then the needle block module 2 contacts the product connector, with a sequence function. At the same time, the needle block module 2 and the pre-stressing block 3 are both floating matched, which can absorb part of the impact force during the contact process to protect the product connector and the needle block module 2.

[0015] like Figures 2 to 3 As shown, in this embodiment, the pre-stressed fixed end 10 includes a long fixed end 11 and a short fixed end 12. The long fixed end 11 is provided with a plurality of holes 110 for interlocking with external equipment. Thus, the pre-stressed fixed end 10 is integrally formed and arranged on both sides of the needle block mounting plate 1. The needle block mounting plate 1 interlocks with the external equipment via the long fixed end 11, and the long fixed end 11 serves to connect and support the needle block mounting plate 1.

[0016] like Figures 2 to 3As shown, in this embodiment, a pair of first springs 13 and a pair of linear bearings 14 are provided on the pre-stressing fixed end 10, and the two ends of the first spring 13 are respectively limited and matched with the pre-stressing fixed end 10 and the pre-stressing block 3, and the pair of linear bearings 14 are both rotatably fitted in the pre-stressing fixed end 10, and a guide pin 140 is provided at one end of the linear bearing 14 close to the pre-stressing block 3, and the guide pin 140 is limited and matched with the pre-stressing block 3. It can be seen that the pre-compression block 3 is floatingly matched with the pre-compression fixed end 10 through the first spring 13 and the linear bearing 14, so that the pre-compression block 3 presses the product soft flat cable without over-pressing the product soft flat cable. The first spring 13 plays a role in over-pressure protection of the product connector. The guide pin 140 is fixed on the linear bearing 14. The linear bearing 14 and the guide pin 140 play a guiding and limiting role for the pre-compression block 3, so that the pre-compression block 3 is vertically matched with the product soft flat cable. At the same time, the linear bearing 14 plays a supporting and fixing role for the guide pin 140.

[0017] like Figures 1 to 2 As shown, in this embodiment, the needle block module 2 is in floating cooperation with the needle block mounting plate 1 through a plurality of contour screws 20 and a plurality of second springs 21. The contour screws 20 pass through the second springs 21 and the needle block module 2 to limit the position of the needle block mounting plate 1. The two ends of the second spring 21 are respectively in limiting cooperation with the needle block mounting plate 1 and the contour screws 20. It can be seen that the needle block module 2 is in floating cooperation with the needle block mounting plate 1 through the contour screws 20 and the second springs 21, so that the needle block module 2 will not over-press the product connector when it is connected to the product connector. The second springs 21 play the role of over-pressure protection for the product connector, and the contour screws 20 play a limiting role for the needle block module 2 and the second spring 21.

[0018] like Figure 3 As shown, in this embodiment, a through hole 15 is provided in the middle of the needle block mounting plate 1, and the through hole 15 cooperates with the needle block module 2. Thus, the through hole 15 provided in the middle of the needle block mounting plate 1 and the cooperation with the protruding portion of the needle block module 2 can reduce the volume of the needle block mechanism and make the whole structure more beautiful.

[0019] like Figure 1 As shown, in this embodiment, the hole 110 provided on the long fixed end 11 is a countersunk hole. Thus, the hole 110 provided on the long fixed end 11 is a countersunk hole, which allows the screw to be sunk into the needle block mounting plate 1, improving the aesthetics of the needle block mounting plate 1. At the same time, the countersunk hole design can increase the contact area between the screw and the needle block mounting plate 1, thereby improving the fastening force.

[0020] like Figures 1 to 2 As shown, in this embodiment, the pre-pressing block 3 is provided with an integrally formed contoured groove on the side away from the guide pin 140. The contoured groove cooperates with the product flexible flat cable on the external device to limit the position. Thus, it can be seen that when the pre-pressing block 3 cooperates with the product flexible flat cable, the contoured groove serves to guide and limit the product flexible flat cable.

[0021] In this embodiment, the working principle of the utility model is as follows:

[0022] like Figures 1 to 3 As shown, the needle block mounting plate 1 is fixed to the external device through the hole 110, and the external device drives the needle block mounting plate 1 to move toward the battery protection board. When the needle block mechanism moves forward, the pre-compression block 3 is supported by the first spring 13 and the linear bearing 14 and is always maintained at the front end of the needle block module 2. The needle block mechanism continues to move forward. First, the pre-compression block 4 precedes the product soft cable part, and the product soft cable is vertically pressed into the limiting groove of the product connector through the contoured groove set on the pre-compression block 4. The needle block mechanism continues to push the needle block module 2 forward, so that the second spring 21 is compressed. At the same time, the linear bearing 14 pushes the pre-compression block 3 to press the product soft cable until the needle block module 2 cooperates with the product connector, thereby realizing the automatic pre-compression function of the product, and the cycle is carried out in sequence.

[0023] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
