Description

Technical Field

[0001] The present invention relates to a connector crimping positioning device, and more particularly to a PCBA printed circuit board connector crimping positioning device. Background Art

[0002] Crimp connectors are commonly used components in current printed circuit boards, and crimp connectors are installed on the circuit board through a crimping process.

[0003] Generally, during the crimping process, it is necessary to position the connector. The traditional method of manually measuring and positioning to determine the crimping position of the connector has high requirements for personnel and is difficult to meet the needs of large-scale synchronous processing.

[0004] In this regard, it is necessary to design some auxiliary devices with limits to position the connector. However, the traditional limit devices are only applicable to small PCBA printed circuit boards. For some large printed circuit boards, the overall positioning device will be too large and inconvenient to operate. Summary of the Invention

[0005] The purpose of the present invention is to provide a PCBA printed circuit board connector crimping positioning device.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A PCBA printed circuit board connector crimping positioning device includes:

[0008] A first device board, which is provided with a first engaging portion and at least two positioning holes, and the first engaging portion and the positioning holes are respectively located on both sides of the first device board;

[0009] A second device board, which is provided with a chute and two limiting block mounting rods. The chute is strip-shaped, and a plurality of positioning sliding holes communicating with it are provided on one side of the chute. The second device board slides relative to the first device board along the direction of the chute through a connecting column sequentially passing through the chute and the positioning hole, and positioning is achieved after the connecting column moves into the positioning sliding hole;

[0010] A plurality of first limiting blocks and a plurality of second limiting blocks. The first limiting blocks are rotatably connected to one limiting block mounting rod of the second device board through connecting pins, and the second limiting blocks are rotatably connected to the other limiting block mounting rod of the second device board through connecting pins.

[0011] The first device board is provided with connecting arms having the same number as the positioning holes, and each positioning hole is respectively located on each connecting arm.

[0012] The number of the chutes is the same as the number of the positioning holes, and the connecting columns passing through the respective positioning holes are respectively located in the respective chutes.

[0013] The positioning slide holes on the slide groove are arranged at equal intervals.

[0014] The number of the positioning slide holes on the slide groove is 4.

[0015] The width of the positioning slide hole is the same as the diameter of the connecting column.

[0016] The first device plate is provided with a hollow avoidance hole.

[0017] The second device plate is provided with a hollow avoidance hole.

[0018] The axis of the connecting pin is perpendicular to the slide groove and parallel to the second device plate.

[0019] Both the first limiting block and the second limiting block are provided with four.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By designing the first device plate and the second device plate, on the one hand, the lateral positioning adjustment is realized. On the other hand, the span can be enlarged through the first device plate, so that the volume can be reduced when applied to a large circuit board. In addition, by using the design of the rotatable limiting block, on the one hand, the position adjustment of the connector in another direction can be realized, and on the other hand, the positioning stability can also be improved.

[0022] 2. By arranging the positioning holes on the connecting arm, the weight can be reduced.

[0023] 3. The adjustment process only requires simple displacement, and the operation is flexible and convenient, improving the installation efficiency and the reliability of the installation quality of the PCBA connector.

[0024] 4. The device is applicable to the installation of PCBA printed circuit board connectors of different specifications.

[0025] 5. The limiting block is flexibly fixed by the connecting pin, which is convenient for disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be described in detail below with reference to the drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and the detailed implementation manner and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0030] A PCBA printed circuit board connector crimping positioning device, as Figures 1 to 3 shown, includes:

[0031] The first device board 1, on which there are a first engaging portion 1-1 and at least two positioning holes 1-2, and the first engaging portion 1-1 and the positioning holes 1-2 are respectively located on both sides of the first device board 1;

[0032] The second device board 2, on which there are a sliding groove 2-1 and two limiting block mounting rods 2-2. The sliding groove 2-1 is strip-shaped, and on one side of the sliding groove 2-1 there are a plurality of positioning sliding holes 2-1-1 communicating therewith. The second device board 2 slides relative to the first device board 1 along the direction of the sliding groove 2-1 through a connecting column 5 sequentially passing through the sliding groove 2-1 and the positioning holes 1-2, and positioning is achieved after the connecting column 5 moves into the positioning sliding holes 2-1-1;

[0033] A plurality of first limiting blocks 4 and a plurality of second limiting blocks 4. The first limiting blocks 4 are rotatably connected to one limiting block mounting rod 2-2 of the second device board 2 through a connecting pin 6, and the second limiting blocks 4 are rotatably connected to the other limiting block mounting rod 2-2 of the second device board 2 through a connecting pin 6.

[0034] By designing the first device board 1 and the second device board 2, on the one hand, lateral positioning adjustment is achieved, and on the other hand, the span can be enlarged through the first device board 1, so that the volume can be reduced when applied to large circuit boards. In addition, by using the design of rotatable limiting blocks, on the one hand, position adjustment in another direction of the connector can be achieved, and on the other hand, the positioning stability can also be improved.

[0035] In some embodiments, the first device board 1 is provided with connecting arms 1-3 having the same number as the positioning holes, and each positioning hole 1-2 is respectively located on each connecting arm 1-3. Designed in this way, by arranging the positioning holes 1-2 on the connecting arms 1-3, there are relatively large gaps between the connecting arms, and the weight can be reduced.

[0036] Generally, the number of the sliding grooves 2-1 is the same as the number of the positioning holes 1-2, and the connecting columns 5 passing through the positioning holes 1-2 are respectively located in the sliding grooves 2-1. In this way, a certain limit can be made on the sliding distance to avoid the large reset time caused by too large a sliding distance. In most of these embodiments, the positioning sliding holes 2-1-1 on the sliding groove 2-1 are arranged at equal intervals. In a certain embodiment, the number of the positioning sliding holes 2-1-1 on the sliding groove 2-1 is 4. Of course, in other embodiments, it can also be other numbers.

[0037] In almost all embodiments, the width of the positioning sliding hole 2-1-1 and the diameter of the connecting column 5 should match, and generally should be the same. In some embodiments, the natural width of the positioning sliding hole 2-1-1 can be slightly smaller than the diameter of the connecting column 5, and there is a certain elasticity between the two. In this way, although it will increase the resistance of the connecting column 5 sliding therein, it can improve the bonding force between the two, thereby avoiding shaking.

[0038] In some embodiments, the first device plate 1 is provided with a hollow avoidance hole. Similarly, in some embodiments, the second device plate 2 is also provided with a hollow avoidance hole.

[0039] In some embodiments, the axis of the connecting pin 6 is perpendicular to the sliding groove 2-1 and parallel to the second device plate 2. In this way, the two adjustment directions can be perpendicular, thereby improving the convenience during the adjustment process.

[0040] Generally, in this embodiment, there are four first limiting blocks 4 and second limiting blocks 4. Of course, in other embodiments, different quantity designs can also be adopted.

[0041] The first device plate 1 and the second device plate 2 are connected and limited by the connecting column 5. The first limiting block 3 and the second limiting block 4 are connected to the second device plate 2 through the connecting pin 6. The first limiting block 3 and the second limiting block 4 can be flipped to fix the assembled device on the crimping equipment. According to the crimping positions of the connectors on the PCBA printed circuit board, the positions of the connecting column 5 in the sliding groove 2-1 of the second device plate 2 are respectively adjusted, and limited through the positioning sliding holes 2-1-1 on the sliding groove 2-1. At the same time, the positions of the first limiting block 3 and the second limiting block 4 are flipped and adjusted. Through the above combined adjustment, the first limiting block 3, the second limiting block 4, and the connecting column 5 form the adjustment of the crimping positions of the connectors in four directions of front, back, left, and right.
