Description

Technical Field

[0001] The present application relates to the field of connector terminals, and in particular to an anti-impact rubber terminal. Background Art

[0002] In the field of electronic connector technology, the continuous development and popularization of electronic products are driving increasing performance requirements for connector terminals. As key components for circuit connections in electronic devices, connector terminals must be designed to meet not only excellent electrical conductivity and mechanical strength but also maintain stability and reliability in complex production environments. Injection molding techniques (such as internal and external mold production) have become a widely used manufacturing method, particularly in wire processing, effectively improving production efficiency and reducing costs.

[0003] However, during the injection molding process, the injection molding material (such as plastic) can easily penetrate through the tiny gaps between the terminal and the wire, especially in the contact area of ​​the connector terminal. This "plastic rush" phenomenon can seriously affect the contact performance of the terminal, leading to problems such as poor signal transmission, increased resistance, and even short circuits, which in turn affects the stability and reliability of the entire electronic system. Therefore, how to effectively prevent the injection molding material from entering the critical area of ​​the connector terminal has become a technical challenge that needs to be solved in the field of connector terminal design.

[0004] Traditional connector terminal designs have many shortcomings in preventing glue impact. For example, the blocking measures of a single structure are often limited in effect and cannot completely prevent the infiltration of injection molding materials. Alternatively, additional sealing structures can be added to improve the anti-glue impact capability, but this may sacrifice other key terminal properties, such as insertion and extraction force, conductivity, etc., resulting in a decline in overall performance. Utility Model Content

[0005] The present application provides a glue-proof terminal design, which forms a multi-level blocking mechanism by arranging multi-level glue baffles (including a first glue baffle and a second glue baffle) in a hollow cylindrical terminal body to more effectively prevent the injection molding material from penetrating into the contact area of ​​the terminal during the inner and outer mold production process.

[0006] In order to achieve the above objectives, this application provides the following technical solutions:

[0007] A rubber-proof terminal includes a terminal body, which is a hollow cylindrical shape. One end of the terminal body is a contact portion, and the other end of the terminal body is a wiring portion. A first rubber baffle plate and a second rubber baffle plate are provided in the inner hole of the terminal body. The first rubber baffle plate is close to the contact portion, and the second rubber baffle plate is close to the wiring portion.

[0008] In one embodiment, a first limiting protrusion ring is provided in the inner hole of the terminal body near the first rubber baffle plate, the side of the first rubber baffle plate facing the contact portion is the first side surface, and the first limiting protrusion ring is located on one side of the first side surface and is used to limit the movement of the first rubber baffle plate toward the contact portion.

[0009] In one embodiment, a second limiting protrusion is provided on the inner hole of the terminal body near the second rubber baffle plate, the side of the second rubber baffle plate facing the first rubber baffle plate is the second side, and the second limiting protrusion is located on one side of the second side, for limiting the movement of the second rubber baffle plate toward the first rubber baffle plate.

[0010] In one embodiment, a first electroplating hole is provided on the terminal body, and the first electroplating hole is close to the contact portion and communicated with the inner hole of the terminal body.

[0011] In one embodiment, a second electroplating hole is provided on the terminal body, and the second electroplating hole is close to the wiring portion and communicated with the inner hole of the terminal body.

[0012] In one embodiment, the cross section of the connection portion is U-shaped.

[0013] In one embodiment, a protrusion is provided in the wiring portion.

[0014] The beneficial effects of this application are:

[0015] This application cleverly incorporates a first and second rubber baffle plate within the inner hole of the terminal body. Together, these two levels of rubber baffle plates form a highly effective barrier against plastic impaction. The first rubber baffle plate, located close to the contact area, directly blocks the infiltration of injection molding material into the contact area, while the second rubber baffle plate further enhances this barrier, ensuring that injection molding material cannot enter critical areas during the production of both inner and outer molds, effectively resolving the plastic impaction issue commonly associated with conventional terminals.

[0020] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] Example 1

[0022] like Figure 1 and Figure 2 As shown, an anti-impact glue terminal includes a terminal body 1, which is a hollow cylindrical shape. One end of the terminal body 1 is a contact part 2 for contacting the terminal of the male connector, and the other end of the terminal body 1 is a wiring part 3 for connecting to the core wire of the wire. A first rubber baffle 4 and a second rubber baffle 5 are provided in the inner hole of the terminal body 1. The first rubber baffle 4 is close to the contact part 2. When the plastic part 11 of the wiring part is injection molded, its main function is to block the injection molding material from penetrating toward the contact part 2. The second rubber baffle 5 is close to the wiring part 3, and together with the first rubber baffle 4, it constitutes a multi-level blocking mechanism to further enhance the anti-impact glue effect.

[0023] like Figure 2 As shown, to limit the movement of the first rubber stopper 4 toward the contact portion 2, a first limiting protrusion 6 is provided in the inner hole of the terminal body 1 near the first rubber stopper 4. The side of the first rubber stopper 4 facing the contact portion 2 is the first side surface, and the first limiting protrusion 6 is located on one side of the first side surface. By physically blocking the first rubber stopper 4, it ensures that the first rubber stopper 4 maintains a stable position during the injection molding process.

[0024] Example 2

[0025] like Figure 2 As shown, based on the first embodiment, this embodiment further provides a second stop ring 7 within the inner hole of the terminal body 1, near the second stop plate 5. The side of the second stop plate 5 facing the first stop plate 4 is the second side surface, and the second stop ring 7 is located on one side of the second side surface to limit the movement of the second stop plate 5 toward the first stop plate 4. This effectively secures both the first stop plate 4 and the second stop plate 5, and they can work together to prevent impact during the injection molding process.

[0026] Example 3

[0027] like Figure 1As shown, in order to improve the conductivity and corrosion resistance of the terminal body 1, this embodiment provides a first electroplating hole 8 and a second electroplating hole 9 on the terminal body 1. The first electroplating hole 8 is close to the contact portion 2 and is connected to the inner hole of the terminal body 1, which is convenient for electroplating the contact portion 2 and the surrounding area. The second electroplating hole 9 is close to the wiring portion 3 and is also connected to the inner hole of the terminal body 1, and is used for electroplating the wiring portion 3 and the surrounding area. Through electroplating treatment, the conductivity and corrosion resistance of the terminal body 1 can be improved, and the service life can be extended.

[0028] like Figure 1 As shown, in order to better adapt to the connection requirements of wires of different specifications, this embodiment optimizes the structure of the connection portion 3. Specifically, the cross-section of the connection portion 3 is U-shaped. This design facilitates the insertion and fixation of the wires, while increasing the contact area between the connection portion 3 and the wires, improving the stability and reliability of the connection.

[0029] like Figure 1 As shown, to further enhance the connection strength between the terminal portion 3 and the wire, this embodiment provides a raised portion 10 within the terminal portion 3. There can be one or more raised portions 10, and their shape and size can be designed according to actual needs. The provision of raised portions 10 increases friction between the terminal portion 3 and the wire, preventing the wire from slipping or loosening during insertion and removal, thereby improving the stability and security of the connection.
