[0002] Connectors are commonly used interface devices in network devices. Their function is to connect network cables and network devices, such as RJ11 and RJ45 connectors.
[0003] The client process of this type of product is a wave soldering process. Operators need to manually insert the plastic column of the connector into the PCB board. If the plastic column is too tight, it will affect the customer's plug-in efficiency and employee fatigue. If the plastic column has too little interference with the plate, there is a risk that the plug-in board is not firm, and the wave soldering will raise the product.
[0004] In addition, general plastic foot columns on the market are only compatible with PCB boards of one thickness. For example, the application number is "2022205297071", and its plastic connecting column can only adapt to PCB boards of one thickness. The commonly used PCB board thicknesses are 1mm, 1.2mm, and 1.6mm. When customers need to use PCB boards of different thicknesses, they need to re-open the mold, which will increase production costs.

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.
[0025] See also Figures 1 to 5 In an embodiment of the utility model, a fixed foot column comprises a fixed column body 1 arranged on a connector, a deformation groove 2 is formed in the fixed column body 1, and the deformation groove 2 at least divides the fixed column body 1 into two elastic parts 3, and at least one of the elastic parts 3 has a tapered surface 4 which is narrow at the top and wide at the bottom on the outer side;
[0026] See also Figure 5 In the past, plastic feet had no elastic design, large lower board force, large product interference in the plug-in board, easy deformation or breakage, and could only adapt to PCB boards of a single thickness. When using PCB boards of different thicknesses, it was necessary to re-open the mold, which would incur a large amount of production costs. At the same time, customers also needed to purchase connectors with a variety of different plastic feet to adapt to the corresponding PCB boards. In the application itself, the fixing column was divided into several elastic parts 3 through the deformation groove 2. After being inserted into the connecting hole of the PCB board, the PCB board could be squeezed and fixed upward due to the setting of the conical surface 4. It could adapt to PCB boards of 1mm, 1.2mm and 1.6mm thickness at the same time. The product did not need to be re-opened, which could reduce development costs. At the same time, since the conical surface 4 on the elastic part 3 could squeeze the PCB board upward, the connection of the PCB board could be made more stable.
[0027] In addition, the included angle a between the conical surface 4 and the PCB board is between 60° and 85°.
[0028] Furthermore, the distance between the top of the fixing column body 1 and the top of the conical surface 4 is the fixing portion 5, and the length of the fixing portion 5 is less than 1 mm. Since the minimum thickness of the current PCB board is 1 mm, if the length of the fixing portion 5 is set long, the PCB board is in the fixing portion 5, and the conical surface 4 on the outside of the elastic portion 3 is difficult to squeeze the PCB board with the smallest thickness. When it is less than 1 mm, even the PCB board with the smallest thickness can also be squeezed, making it more firmly fixed.
[0029] Furthermore, the deformation groove 2 is in a trumpet shape that is narrow at the top and wide at the bottom.
[0030] Furthermore, the top of the deformation groove 2 is arc-shaped. By setting the top of the deformation groove 2 to be arc-shaped, its elastic force can be enhanced. At the same time, the arc-shaped setting relative to the right-angle setting can further enhance its service life and prevent breakage.
[0031] Furthermore, the front end of the elastic part 3 has a guide portion 6 formed thereon, and the guide portion 6 can be easily inserted into the PCB.
[0032] Furthermore, the top of the deformation groove 2 does not exceed the fixing portion 5. Since the fixing foot is integrally formed with the bottom of the connector body, if the top of the deformation groove 2 exceeds the fixing portion 5, it will reach the connector body. If it is subjected to stress and deformation for a long time, it may cause the connector body to deform. For this reason, in the present application, the deformation groove 2 does not exceed the fixing portion 5, and the elastic portion 3 will not affect the connector body.
[0033] The utility model also provides an RJ45 connector, including a connector body 7 and the above-mentioned fixed feet, the fixed feet having two, formed at the bottom of the connector body 7, the feet of general products on the market are only compatible with a PCB board of one specification thickness, when the customer needs to change the thickness of the PCB board, it is necessary to re-open the mold, the RJ45 connector in this solution, by adopting the above-mentioned fixed feet, can make the connection with the PCB board more stable, at the same time, can adapt to PCB boards of 1mm, 1.2mm and 1.6mm thickness at the same time, the product does not need to be re-opened, which can reduce the development cost.
[0034] Furthermore, the elastic part 3 has two conical surfaces 4 arranged on the inner elastic part 3. By arranging the conical surface 4 on the inner side, the fixed foot column can fix the PCB board in a single-sided inward buckle manner, so that when the employee inserts the plug, the elastic part 3 can be deformed to reduce the hard interference force when it is buckled with the PCB board due to its elasticity. When the elastic part 3 is inserted into place, the elastic part 3 can rebound to firmly fix the PCB board, effectively reducing the plug-in force and improving production efficiency.
[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
