Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to an installation device for a solderless press-fit connector. Background Technology

[0002] To meet customer needs, there are more and more ways to mate board-to-board connectors. Among them, the spherical structure of solderless press-fitting can be quickly press-fitted and installed without soldering. However, due to the inconsistent specifications and dimensions of the contact parts, the size of the solderless spherical structure of mixed connectors is inconsistent. During press-fitting, the height of the solderless spherical structure is different and cannot be pressed in at the same time.

[0003] If fisheyes of different sizes are forcibly installed at the same time, it is very easy for them to wobble or get stuck, which seriously affects production efficiency and quality. Therefore, traditional connector installation requires fisheyes of different sizes to be installed separately, which leads to low efficiency in connector installation.

[0004] Meanwhile, connectors are prone to misalignment during press-fitting, which can cause jamming or scratches when the fisheye is connected to the printed circuit board, adversely affecting the press-fitting process and even damaging the fisheye structure. This results in a high defect rate and poor production quality. Utility Model Content

[0005] To address the above problems, this utility model provides an installation device for a solderless press-fit connector, which solves the aforementioned issues.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an installation device for a solderless press-fit connector, comprising a base and a pressure plate, wherein two guide posts are connected to the top of the base, guide grooves are provided on both sides of the pressure plate, the two guide posts are respectively disposed in the two guide grooves, and a positioning block is connected to the bottom of the pressure plate;

[0007] A positioning seat is connected to one side of the base, and a buffer groove is provided between the positioning seat and the base. A spring is connected in the buffer groove, and a buffer plate is connected to the top of the spring.

[0008] The top of the positioning seat is provided with a reference groove, and several reference columns are connected to the top of the positioning seat.

[0009] Preferably, a printed circuit board is mounted on the top of the base, and the printed circuit board is connected to the reference slot and the reference column.

[0010] Preferably, the base is provided with a connector body, which is disposed between the printed circuit board and the pressure plate.

[0011] Preferably, a positioning post is connected to one side of the base, and a plurality of positioning slots are provided on one side of the positioning seat, and the connector body is aligned with the positioning post and the positioning slots.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This application, by positioning and limiting the connector and cooperating with the flexible support of the spring, can press-fit all sizes of fisheye contacts in a mixed-assembly connector into place at one time, solving the problem that fisheye contacts of different sizes need to be installed separately when installing traditional connectors, which is conducive to improving the work efficiency of connector installation.

[0014] 2. This application uses a flexible support spring and buffer plate in the buffer groove to keep the connector horizontal during the press-fitting process, avoiding swaying. This solves the problem that swaying is easy to occur during connector press-fitting, which can cause jamming, scratching, or even damage to the fisheye structure when connecting the fisheye to the printed circuit board. This helps to reduce the defect rate of products and improve the production quality of products. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] Please see Figures 1 to 5An installation device for a solderless press-fit connector includes a base 1 and a pressure plate 5. The top of the base 1 is connected to two guide posts 3. Guide grooves 4 are provided on both sides of the pressure plate 5. The two guide posts 3 are respectively set in the two guide grooves 4. The bottom of the pressure plate 5 is connected to a positioning block 6. The positioning block 6 is aligned and positioned with the fisheye structure of the connector body 15.

[0023] During press-fitting, the guide groove 4 of the pressure plate 5 moves outside the guide post 3, causing the pressure plate 5 to press down on the connector body 15. It is important to note that the size of the guide groove 4 is larger than that of the guide post 3 because the pressure plate 5 works frequently, requiring the guide groove 4 to move frequently outside the guide post 3. The larger size of the guide groove 4 can reduce the labor intensity of personnel during press-fitting.

[0024] Furthermore, it should be noted that although the guide groove 4 is larger than the guide post 3, the pressure plate 5 will not shake arbitrarily. This is because the positioning block 6 is aligned with the fisheye structure of the connector body 15. Therefore, after the pressure plate 5 is aligned and engaged with the connector body 15, the movement of the pressure plate 5 will not cause any swaying.

[0025] A positioning seat 10 is connected to one side of the base 1. A buffer groove 7 is provided between the positioning seat 10 and the base 1. A spring 8 is connected in the buffer groove 7. A buffer plate 9 is connected to the top of the spring 8. When the pressure plate 5 moves to press down the connector body 15, the pressure plate applies downward pressure. The connector body 15 moves down synchronously with the large and small fisheyes. Because the large fisheye is longer (i.e., the installation position is lower), it will contact the upper edge of the opening of the printed circuit board first. At this time, although the large fisheye is in contact, it is not fully pressed in, while the small fisheye is still in the state of not contacting the printed circuit board 14.

[0026] Next, the pressure plate 5 drives the connector body 15 to continue pressing down. At this time, the bottom of the connector body 15 contacts the buffer plate 9 and presses down the spring 8. The connector body 15, with the small fisheye, continues to move down and contacts the upper edge of the opening of the printed circuit board 14, completing the transition from suspension to contact. During this process, the large fisheye also moves down with the connector body 15 as a whole and begins to slowly press into the opening of the printed circuit board 14. However, the pressing speed is buffered by the resistance of the spring 8 to avoid the large fisheye being forcibly pressed in. The small fisheye on the other side has not yet been inserted. The two sides are subjected to different forces and wobble occurs, causing the connector to jam or scratch during the pressing process. At the same time, the two springs 8 on the buffer groove 7 will ensure that the connector remains horizontal during the pressing process.

[0027] Then, when the small fisheye contacts the printed circuit board 14, the pressure plate 5 continues to apply pressure. At this time, both the large and small fisheyes are subjected to downward pressing force, and the pressure at both ends of the connector body 15 is automatically balanced by the flexible support of the spring 8. Meanwhile, both the large and small fisheyes have been positioned and pressed into the printed circuit board 14, so it will also ensure that the connector is always horizontal.

[0028] Finally, the larger fisheye continues to be pressed in while the smaller fisheye is pressed in simultaneously, and both are fully inserted into the opening of the printed circuit board 14 at the same time, achieving one-time pressing and installation. This solves the problem that fisheyes of different sizes need to be installed separately when installing traditional connectors, which helps to improve the efficiency of connector installation.

[0029] Moreover, the flexible support spring 8 and buffer plate 9 in the buffer groove 7 can keep the connector horizontal during the press-fitting process, avoiding swaying. This solves the problem that swaying is easy to occur during connector press-fitting, which can cause jamming, scratching, or even damage to the fisheye structure when connecting the fisheye to the printed circuit board 14. This helps to reduce the defect rate of the product and improve the production quality of the product.

[0030] The top of the positioning seat 10 is provided with a reference groove 11, and the top of the positioning seat 10 is connected with several reference posts 12. The printed circuit board 14 is positioned and fixed by the reference groove 11 and the reference posts 12 to ensure that the position of the printed circuit board 14 is fixed, so as to ensure that the connector body 15 is aligned and pressed with the printed circuit board 14.

[0031] A printed circuit board 14 is mounted on the top of the base 1, and the printed circuit board 14 is connected to the reference slot 11 and the reference post 12.

[0032] A connector body 15 is provided on the base 1, and the connector body 15 is disposed between the printed circuit board 14 and the pressure plate 5.

[0033] A positioning post 2 is connected to one side of the base 1, and several positioning slots 13 are opened on one side of the positioning seat 10. The connector body 15 is aligned with the positioning post 2 and the positioning slots 13. The connector body 15 is positioned by the positioning post 2 and the positioning slots 13, so that the connector body 15 is fixed in the horizontal direction and can be subjected to the force of the pressure plate 5 in the vertical direction, thereby driving the connector body 15 to move and complete the press-fitting work with the printed circuit board 14.

[0034] When using this utility model:

[0035] First, the connector body 15 is placed on the printed circuit board 14. The connector body 15 is aligned with the positioning post 2 and the positioning groove 13. The connector body 15 is positioned by the positioning post 2 and the positioning groove 13, so that the connector body 15 is fixed in the horizontal direction and can be subjected to the force of the pressure plate 5 in the vertical direction, thereby driving the connector body 15 to move and complete the press-fitting work with the printed circuit board 14.

[0036] Secondly, during the pressing process, the guide groove 4 of the pressure plate 5 moves outside the guide post 3, causing the pressure plate 5 to move and press down on the connector body 15. The connector body 15 moves down synchronously with the large and small fisheyes. Because the large fisheye is longer (i.e., the installation position is lower), it will contact the upper edge of the opening of the printed circuit board first. At this time, although the large fisheye is in contact, it is not fully pressed in, while the small fisheye is still in the state of not contacting the printed circuit board 14.

[0037] Then, the pressure plate 5 drives the connector body 15 to continue to press down. At this time, the bottom of the connector body 15 contacts the buffer plate 9 and presses down the spring 8. The connector body 15, with the small fisheye, continues to move down and contacts the upper edge of the opening of the printed circuit board 14, completing the transition from suspension to contact. During this process, the large fisheye also moves down with the connector body 15 as a whole and begins to slowly press into the opening of the printed circuit board 14. However, the pressing speed is buffered by the resistance of the spring 8 to avoid the large fisheye being pressed in hard. The small fisheye on the other side has not yet been inserted. The two sides are subjected to different forces and wobble occurs, causing the connector to jam or scratch during the pressing process. At the same time, the two springs 8 on the buffer groove 7 will ensure that the connector remains horizontal during the pressing process.

[0038] Finally, when the small fisheye contacts the printed circuit board 14, the pressure plate 5 continues to apply pressure. At this time, both the large and small fisheyes are subjected to downward pressing force, and the pressure at both ends of the connector body 15 is automatically balanced by the flexible support of the spring 8. At the same time, both the large and small fisheyes have entered the printed circuit board 14 and completed the positioning and pressing, so it will also ensure that the connector is always horizontal. The large fisheye continues to be pressed in, and the small fisheye is pressed in simultaneously. Both of them are fully inserted into the opening of the printed circuit board 14 at the same time, realizing one-time pressing and installation.
