Description

Technical Field

[0001] The utility model relates to the technical field of electronic connectors, in particular to an electronic connector with a long service life. Background Art

[0002] Electronic connectors are also often called circuit connectors, electrical connectors, and conductor devices that connect two conductor bridges on a loop so that current or signals can flow from one conductor to another. They are widely used in various electrical circuits to connect or disconnect current or signals.

[0003] Some electronic connectors currently on the market, such as the commonly used USB (Universal Serial Bus), have their sockets worn out due to repeated plugging and unplugging over time, resulting in loose interfaces. The connection wires of the plugs will break contact if the plugs are slightly disturbed, which may cause data loss in severe cases. In addition, the temperature of the electronic connectors will rise during operation, thereby accelerating the oxidation of circuit contacts and causing poor contact.

[0004] Based on this, a long-life electronic connector is now provided, which can improve or even eliminate the disadvantages of the existing devices. Utility Model Content

[0005] The utility model aims to provide an electronic connector with a long service life to solve the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A long-life electronic connector comprises a female socket, wherein the female socket is matched with a plug.

[0008] On the basis of the above technical solutions, the present invention also provides the following optional technical solutions:

[0009] In an optional solution: a plurality of matching limiting mechanisms are provided inside the female socket and outside the plug, and a heat sink is provided on the upper end surface of the female socket.

[0010] In an optional scheme: the limiting mechanism includes a plurality of limiting cavities arranged outside the mother seat, a limiting ball is arranged in the limiting cavity, the upper end of the limiting ball is slidably connected to the lower end of the spring, the upper end of the spring is in contact with the top of the limiting cavity, a limiting ring is arranged at the bottom of the limiting cavity to prevent the limiting ball from falling out, the upper end of the limiting ring is slidably connected to the lower end of the limiting ball, the outer surface of the plug is provided with a plurality of limiting grooves and grooves, and the outer surface of the plug is also provided with a limiting ring.

[0011] In an optional solution: the limiting groove is a concave spherical surface, and the radius of the spherical surface is consistent with the radius of the limiting ball.

[0012] In an optional solution: the groove is distributed on the track where the limiting ball slides on the surface of the plug when the plug is inserted into the female socket, and the groove is a cylindrical surface.

[0013] In an optional solution: when the plug is fully inserted into the female socket, the position of the limiting groove corresponds to the position of the limiting ball.

[0014] In an optional solution, when the position of the limiting groove corresponds to the position of the limiting ball one by one, the limiting ring just contacts the outer end surface of the female seat.

[0015] In an optional solution: the spring is in a compressed state when the plug is not inserted.

[0016] In an optional solution: the maximum distance between the groove and the inner wall of the female seat is slightly smaller than the maximum height of the portion of the lower end of the limiting ball exposed from the lower end of the limiting ring.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The utility model uses the interaction between the limiting mechanism on the female socket and the limiting mechanism on the plug that matches the female socket to make the connection between the plug and the female socket tight and difficult to shake. Moreover, since the contact points between the limiting structures are rolling contact, compared with the structure using spring sheet sliding contact, the contact points of the limiting structure of the utility model are less prone to wear, which greatly increases the durability.

[0019] 2. The utility model assists heat dissipation through the heat dissipation structure on the top of the female seat, thereby reducing the operating temperature of the entire electronic connector, which is beneficial to delaying the oxidation of the circuit contacts and increasing the service life.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Example 1

[0029] In one embodiment, Figure 1-Figure 6 As shown, a long-life electronic connector includes a female socket 101, and the female socket 101 is equipped with a plug 102;

[0030] In this embodiment, a plurality of matching limiting mechanisms are provided inside the female socket 101 and outside the plug 102. The limiting mechanisms enable the female socket 101 and the plug 102 to be tightly and stably connected to each other. Compared with the general limiting mechanisms using elastic sheets, the limiting mechanisms in this embodiment have less wear and tear during the plugging and unplugging process and have a longer service life. A heat sink 103 is provided on the upper end surface of the female socket 101. The heat sink 103 helps the female socket 101 to dissipate heat, reduce the working temperature of the electronic connector, delay the oxidation of the circuit contacts, and extend the service life.

[0031] In one embodiment, Figure 1-Figure 4 As shown, the limiting mechanism includes a plurality of limiting cavities 204 arranged at the upper end and both sides of the female seat 101, a limiting ball 206 is arranged in the limiting cavity 204, the upper end of the limiting ball 206 is slidably connected with the lower end of the spring 205, the upper end of the spring 205 is in contact with the top of the limiting cavity 204, a limiting ring 207 is arranged at the bottom of the limiting cavity 204 to prevent the limiting ball 206 from falling out, the upper end of the limiting ring 207 is slidably connected with the lower end of the limiting ball 206, a plurality of limiting grooves 203 and grooves 202 are arranged on the outer surface of the plug 102, and a limiting ring 201 is also arranged on the outer surface of the plug 102, when the plug 102 is inserted into the female seat 101, the limiting ball 206 is lifted up, and at the same time, the compressed spring 205 applies a force to the plug 102 through the limiting ball 206, and under the cooperation of the plurality of limiting cavities 204 and the limiting grooves 203, the female seat 101 and the plug 102 are tightly and stably combined;

[0032] In one embodiment, Figure 1 and Figure 4As shown, the limiting groove 203 is a concave spherical surface, and the radius of the spherical surface is consistent with the radius of the limiting ball 206. At this time, when the limiting ball 206 contacts the limiting groove 203, the contact surface is the largest and most stable;

[0033] In one embodiment, Figure 1 and Figure 3 As shown, the grooves 202 are distributed on the track where the limiting ball 206 slides on the surface of the plug 102 when the plug 102 is inserted into the female socket 101. The grooves 202 are cylindrical or conical. This design can reduce the pressure at the contact point between the plug 102 and the limiting ball 206 when the limiting ball 206 does not reach the position of the corresponding limiting groove 203 during the process of the plug 102 being inserted into the female socket 101, so as to reduce wear and extend the service life.

[0034] In one embodiment, Figure 3 and Figure 5 As shown, when the plug 102 is fully inserted into the female socket 101, the position of the limiting groove 203 corresponds to the position of the limiting ball 206. Only when all the limiting balls 206 are aligned with the corresponding limiting grooves 203, the combination between the female socket 101 and the plug 102 is in the most stable state.

[0035] In one embodiment, Figure 2 As shown, when the position of the limiting groove 203 corresponds to the position of the limiting ball 206 one by one, the limiting ring 201 is just in contact with the outer end surface 104 of the female seat 101, and the limiting ring 201 plays an auxiliary role in the cooperation between the limiting groove 203 and the limiting ball 206, preventing the limiting groove 203 and the limiting ball 206 from collectively misaligning.

[0036] Example 2

[0037] In one embodiment, Figure 1 As shown, the spring 205 is in a compressed state when the plug 102 is not inserted, so that when the plug 102 is inserted into the female socket 101, the spring 205 can have sufficient force to apply to the plug 102 through the stop ball 206;

[0038] In one embodiment, Figure 1 As shown, the maximum distance between the groove 202 and the inner wall of the female socket 101 is slightly smaller than the maximum height of the portion of the lower end of the limiting ball 206 exposed from the lower end of the limiting ring 207, so that when the plug 102 is inserted into the female socket 101, even if most of the limiting balls 206 are in the groove 202, the plug 102 can still be subjected to the force transmitted by the limiting balls 206, thereby maintaining stability, reducing unnecessary friction between the circuit contacts of the female socket 101 and the plug 102, and extending the service life;

[0039] The above embodiment discloses a long-life electronic connector, wherein when the plug 102 is not inserted into the female socket 101, the spring 205 inside the upper limit cavity 204 of the female socket 101 is in a compressed state, the lower part of the limiting ball 206 is in close contact with the upper part of the limiting ring 207, and the bottom of the limiting ball 206 passes through the limiting ring 207 and is exposed outside the lower end of the limiting ring 207. When the plug 102 is inserted into the female socket 101, the limiting ball 206 is pushed up to the inside of the limiting cavity 204 by the groove 202 or the outer shell of the plug 102, and there is rolling contact between the limiting ball 206 and the groove 202 or the outer shell of the plug 102, thereby reducing friction. Due to the presence of the groove 202, the limiting ball 206 is The thrust received is smaller, which further reduces friction, thereby reducing wear and improving durability. At the same time, the spring 205 applies a reaction force to the plug 102 through the limiting ball 206. With the cooperation of multiple limiting cavities 204, the plug 102 and the female socket 101 are stably combined. When the limiting ring 201 on the plug 102 contacts the outer end face 104 on the female socket 101, all the limiting balls 206 correspond to a limiting groove 203. At this time, the female socket 101 and the plug 102 are tightly combined. At the same time, under the action of the heat sink 103, the temperature of the electronic connector during operation is significantly reduced, which delays the oxidation process of the internal circuit contacts of the electronic connector and improves the service life.

[0040] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
