Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of connectors, and in particular, to a connector. Background Art
[0002] A connector is an important component in electronic devices. The holding force of terminals has a great impact on the connection reliability of the connector. Generally speaking, when the terminal holding force is high, the two inserted terminals are not easily separated. For existing connectors, the friction between the conductive pins and the terminal seat will cause the conductive pins or the terminal seat to be worn and generate debris. The generated debris accumulates between the conductive pins and the mounting holes for mounting the conductive pins on the terminal seat, resulting in cracks easily appearing on the wall surface near the mounting holes. The cracks will loosen the connection between the terminal seat and the conductive pins, resulting in a decrease in the holding force of the terminals, thereby causing unstable connection. Summary of the Invention

[0024] Refer to Figure 1 and Figure 2 , which shows connectors of some embodiments. The connector includes a base 101 and a conductive member 102. The base 101 is made of an insulating material (for example, PBT plastic can be selected), and the conductive member 102 is made of a conductor material (for example, a copper-nickel alloy with a relatively small resistance can be selected); the base 101 includes a connection cavity 104, and the connection cavity 104 is used to accommodate other terminals or connection components. One end of the conductive member 102 is located in the connection cavity 104, and one end of the conductive member 102 located in the connection cavity 104 is used to connect with other terminals or connection components (for example, to achieve the connection between male and female terminals), and the end of the conductive member 102 far from the connection cavity 104 passes out of the connection cavity 104 and is used to connect with a wire.
[0025] Refer to Figure 1 , Figure 3 and Figure 6, Specifically, the base 101 includes a mounting wall 103. The mounting wall 103 is one of the enclosing structures that enclose to form a connection cavity 104. An installation hole 301 is formed in the mounting wall 103. The installation hole 301 is a through hole that penetrates the mounting wall 103 in the front-rear direction. The conductive member 102 passes through the installation hole 301, and the conductive member 102 is in interference connection with the installation hole 301; a first groove 302 is formed in the side wall of the installation hole 301. Refer to Figure 4 , The length direction of the first groove 302 is the front-rear direction, and the first groove 302 communicates with the side of the installation hole 301.
[0026] The conductive member 102 is in interference connection with the base 101. During the assembly of the connector or the insertion and extraction with other terminals, due to the friction or other interactions between the conductive member 102 and the base 101, the base 101 or the conductive member 102 will be worn to generate some debris. These debris can move into the first groove 302 communicating with the installation hole 301 under the action of its own gravity or other external forces (such as the frictional force exerted by the base 101 or the conductive member 102 on the debris). The debris is not easily clamped between the conductive member 102 and the wall surface of the installation hole 301, nor is it easily accumulated between the conductive member 102 and the wall surface of the installation hole 301. Therefore, the side wall of the installation hole 301 will not be overly squeezed due to excessive debris accumulation and crack; there is a stable interference amount between the base 101 and the conductive member 102, the connection between the two is firm, the terminal holding force of the connector is stable, and the connection reliability is high.
[0027] In some embodiments, there are two first grooves 302, and the two first grooves 302 are respectively arranged on both sides of the installation hole 301; specifically, refer to Figure 3 and Figure 4 , the first grooves 302 are respectively arranged on the left and right sides of the installation hole 301. If the first groove 302 is only arranged on one side of the installation hole 301, then if the position where the debris is generated is on the other side of the installation hole 301, the generated debris will be difficult to enter the first groove 302, and the debris will accumulate between the conductive member 102 and the wall surface of the installation hole 301; therefore, arranging a first groove 302 on each side of the installation hole 301 can reduce the potential area of debris accumulation and reduce the risk of cracks on the wall surface of the installation hole 301.
[0028] In some embodiments, the conductive member 102 includes a connecting portion. The connecting portion is in interference connection with the installation hole 301, and the cross section of the connecting portion is rectangular. Correspondingly, the cross section of the installation hole 301 is also rectangular. Specifically, the connecting portion is the section of the conductive member 102 passing through the installation hole 301. Combining Figure 3 and Figure 4 , the cross section mentioned here, the normal direction of which is the same as Figure 4The front / rear directions are the same. The cross-sections of the mounting holes 301 and the conductive members 102 are both rectangular to reduce the complexity of the shapes of the mounting holes 301 and the conductive members 102 and facilitate processing and production. In some embodiments, chamfering is performed at the corners of the conductive members 102 and the corners of the side walls of the mounting holes 301 to remove burrs and facilitate assembly.
[0029] In some embodiments, with reference to Figure 3 and Figure 4 the cross-section of the first groove 302 is trapezoidal, and one of the walls of the first groove 302 corresponds to the "hypotenuse of the trapezoid". Such a shape setting is mainly to facilitate the separation of the base 101 from the mold during the production process.
[0030] In other embodiments, the number, shape, and specific position of the first grooves 302 can be adjusted. For example, first grooves 302 are also provided on the side walls above and below the mounting holes 301, or the cross-section of the first groove 302 is set to be semi-circular; the shape of the mounting holes 301 can also be adjusted, such as being set as circular holes. The remaining feasible setting methods are not listed one by one here.
[0031] It should be noted that the number of the first grooves 302 should not be too large, otherwise the wall area of the mounting holes 301 in contact with the conductive members 102 will be reduced; since the connection between the mounting holes 301 and the conductive members 102 is an interference connection, if the wall area of the mounting holes 301 is too small, the pressure on the wall will be too large, which is likely to cause deformation and damage to the interference connection between the conductive members 102 and the mounting holes 301, resulting in loosening of the connection between the mounting holes 301 and the conductive members 102, and thus making the terminal retention force unstable. Similarly, the width of the first groove 302 should not be too large (taking Figure 3 and Figure 4 as an example, the width direction of the first groove 302 is the up / down direction), otherwise it will also cause the wall area of the mounting holes 301 in contact with the conductive members 102 to be too small, thereby making the terminal retention force unstable.
[0032] In other embodiments, the end face of the first groove 302 is flush with the end face of the mounting hole 301. For example: the mounting hole 301 is a through hole, the front end of the mounting hole 301 is located on the front side surface of the mounting wall 103, and the rear end of the mounting hole 301 is located on the rear side surface of the mounting wall 103; for the first groove 302, the front end of the first groove 302 extends to the front side surface of the mounting wall 103, or the rear end of the second groove 303 extends to the rear side surface of the mounting wall 103 (not shown in detail in the specification drawings). Such a setting can enable the debris in the first groove 302 to fall out of the first groove 302, avoiding the situation where the first groove 302 cannot function due to excessive accumulation of debris in the first groove 302, thereby improving the service life of the connector.
[0033] With reference toFigure 5 , in some other embodiments, the conductive member 102 includes a main body 501 and a hook body 502, and the hook body 502 is connected to the outer edge of the main body 501; referring to Figure 6 , the end of the hook body 502 can penetrate into the base 101 to enhance the connection tightness between the conductive member 102 and the base 101.
[0034] Combined with Figures 3 to 5 , in some embodiments, the hook body 502 can be arranged on the left and right sides of the main body 501. After the conductive member 102 is assembled into the mounting hole 301, the upper half of the end of the hook body 502 penetrates into the wall surface of the mounting hole 301. By the penetration of the hook body 502, the interference amount (or interference fit amount) between the conductive member 102 and the base 101 is increased, which is beneficial to increasing the terminal holding force of the connector. The lower half of the end of the hook body 502 will be located in the first groove 302 and does not need to penetrate into the wall surface of the first groove 302.
[0035] Referring to Figure 3 and 4 , in some embodiments, the base 101 is provided with a second groove 303, and one end of the mounting hole 301 is arranged on the wall surface of the second groove 303; specifically, the mounting wall 103 is provided with a second groove 303, and one of the wall surfaces (the rear wall surface) of the second groove 303 is a supporting wall 401, and the front end of the mounting hole 301 is arranged on the supporting wall 401; referring to Figure 5 , the conductive member 102 includes a positioning portion 503, and the positioning portion 503 is connected to the outer edge of the main body 501, and the positioning portion 503 can be accommodated in the second groove 303. Referring to Figure 1 and Figure 2 , during the assembly process of the connector, it is necessary to first pass the conductive member 102 through the mounting hole 301 from front to back, and then bend the rear end of the conductive member 102 downward. The supporting wall 401 of the second groove 303 can support the positioning portion 503 to prevent the section of the conductive member 102 located in the connection cavity 104 from moving backward and passing through the mounting hole 301 during the assembly process or the plugging process; the remaining side walls of the second groove 303 can also support the positioning portion 503 to prevent the conductive member 102 from rotating or shifting. Therefore, the arrangement of the second groove 303 and the positioning portion 503 can ensure the stability of the position of the conductive member 102, avoid poor contact caused by the position change of the conductive member 102, and thus ensure the reliability and stability of the connector during connection.
[0036] Referring to Figure 5 and Figure 6 , in some embodiments, the hook body 502 is arranged to extend in the direction of the positioning portion 503 based on the connection between the hook body 502 and the main body 501. Referring to Figure 5, the end of the hook body 502 faces forward. Considering the assembly process of the conductive member 102 and the base 101 mentioned above, the hook body 502 is an "inverted hook". When the conductive member 102 is inserted into the base 101, the resistance caused by the interaction between the hook body 502 and the base 101 is relatively small. After the conductive member 102 is inserted into the base 101, if one wants to extract the conductive member 102 from the front, the resistance caused by the interaction between the hook body 502 and the base 101 is large, and it is difficult to extract the conductive member 102. The cooperation between the positioning portion 503 and the second groove body 303 can prevent the conductive member 102 from moving backward and rotating. At the same time, this setting method of the hook body 502 can prevent the conductive member 102 from moving forward, improving the position stability of the conductive member 102, and thus improving the reliability and stability of the connector during connection.
[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
