[0001] The utility model relates to the technical field of connectors, in particular to a fully plastic leak-proof connector. Background Art

[0002] An electronic connector, also known as a circuit connector or an electrical connector, is a conductor device that bridges two conductors on a circuit, enabling current or signals to flow from one conductor to another. The component used to complete the electrical connection between circuits or electronic devices is called a connector, which is the bridge between the two. It is widely used in various electrical circuits and plays the role of connecting or disconnecting current or signals.

[0003] However, when the existing connectors are assembled with terminals, the connectors usually use a metal shell and a terminal for magnetic attraction plug-in fixation. This makes the terminals more affected by electromagnetic interference during use. Moreover, there is a lack of a connecting piece between the tail end of the terminal and the connector, and it is easy to have a glue leakage problem during injection molding. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fully plastic leak-proof connector. This kind of connector can realize the fully plastic assembly of the connecting terminals, reduce electromagnetic interference, and add a rear plug to the wire welding part to ensure that the formed wire leaks glue into the connector.

A rear plug is detachably installed at the rear end of the main body. On both sides of the opening at the top of the main body, clamping and positioning blocks are integrally formed respectively. On both sides of the top of the rear plug, positioning grooves are respectively opened. The first terminal and the second terminal are respectively installed between the main body and the rear plug.

[0006] Preferably, a first jack and a second jack are respectively penetrated through the front surface of the main body and the back surface of the rear plug.

[0007] Preferably, first rear end blocks and first front end blocks are integrally formed at both ends of the first terminal respectively. The first rear end blocks and the first front end blocks at both ends of the first terminal are respectively inserted into the second jack and the first jack.

[0008] Preferably, second rear end blocks and second front end blocks are integrally formed at both ends of the second terminal respectively. The second rear end blocks and the second front end blocks at both ends of the second terminal are respectively inserted into the corresponding second jack and first jack.

[0009] Preferably, the clamping and positioning blocks on both sides of the top of the main body are respectively slidably clamped in the corresponding positioning grooves on the top of the rear plug.

[0010] Preferably, the first terminal is a 4PIN terminal, the second terminal is a 5PIN terminal, the ends of the first terminal and the second terminal close to the main body are of a hollow circular structure, and the ends of the first terminal and the second terminal close to the rear plug are of an arc structure.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, the first terminal and the second terminal are respectively inserted into the corresponding first jack and second jack on the main body and the rear plug through the first rear end block, the first front end block, the second rear end block and the second front end block, and are sealed by injecting glue. The clamping positioning block of the main body is slidably clamped in the positioning groove on the top of the rear plug to form a fully plastic connector housing.

Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Please refer to Figures 1-4, the present utility model provides a technical solution: a fully plastic leak-proof glue connector, which includes a main body 1, a first terminal 3, and a second terminal 4. A rear plug 2 is detachably installed at the rear end of the main body 1, and clamping and positioning blocks 12 are integrally formed on both sides of the top opening of the main body 1;

[0020] Positioning grooves 22 are respectively opened on both sides of the top of the rear plug 2, and the first terminal 3 and the second terminal 4 are respectively installed between the main body 1 and the rear plug 2;

[0021] The first terminal 3 and the second terminal 4 are respectively inserted into the corresponding first jack 11 and second jack 21 on the main body 1 and the rear plug 2 through the first rear end block 31, the first front end block 32, the second rear end block 41, and the second front end block 42, and are sealed by injecting glue. The clamping and positioning block 12 of the main body 1 slides and clamps in the positioning groove 22 at the top of the rear plug 2 to form a fully plastic connector housing. In this way, the connector is assembled through the fully plastic housing, reducing the electromagnetic interference to the connection of the terminals. By increasing the assembly of the tails of the first terminal 3 and the second terminal 4, and adding the rear plug 2 at the wire soldering part, it is ensured that the formed wire leaks glue into the connector.

[0022] Among them, a first jack 11 and a second jack 21 are respectively penetrated through the front surface of the main body 1 and the back surface of the rear plug 2. First rear end blocks 31 and first front end blocks 32 are integrally formed at both ends of the first terminal 3. The first rear end blocks 31 and first front end blocks 32 at both ends of the first terminal 3 are respectively inserted into the second jack 21 and the first jack 11. Second rear end blocks 41 and second front end blocks 42 are integrally formed at both ends of the second terminal 4. The second rear end blocks 41 and second front end blocks 42 at both ends of the second terminal 4 are respectively inserted into the corresponding second jack 21 and first jack 11. The first terminal 3 and the second terminal 4 are respectively inserted into the corresponding first jack 11 and second jack 21 on the main body 1 and the rear plug 2 through the first rear end block 31, the first front end block 32, the second rear end block 41, and the second front end block 42, and are sealed by injecting glue. By increasing the assembly of the tails of the first terminal 3 and the second terminal 4, and adding the rear plug 2 at the wire soldering part, it is ensured that the formed wire leaks glue into the connector.

[0023] Among them, the clamping and positioning blocks 12 on both sides of the top of the main body 1 respectively slide and engage with the corresponding positioning grooves 22 at the top of the rear plug 2. The first terminal 3 is a 4PIN terminal, and the second terminal 4 is a 5PIN terminal. One end of the first terminal 3 and the second terminal 4 close to the main body 1 is a hollow circular structure, and one end of the first terminal 3 and the second terminal 4 close to the rear plug 2 is an arc structure. The clamping and positioning block 12 of the main body 1 slides and clamps in the positioning groove 22 at the top of the rear plug 2 to form a fully plastic connector housing. In this way, the connector is assembled through the fully plastic housing, reducing the electromagnetic interference to the connection of the terminals.

[0024] Working principle: When assembling the connector and the terminals, first, the first front end block 32 on the first terminal 3 and the second front end block 42 on the second terminal 4 are respectively assembled side by side with the first jack 11 on the main body 1;

[0025] Then, the rear plug 2 and the main body 1 are assembled. The clamping positioning block 12 on the main body 1 is slidably clamped in the positioning groove 22 at the top of the rear plug 2 to form a fully plastic connector housing. At this time, the first rear end block 31 and the second rear end block 41 on the first terminal 3 and the second terminal 4 are directly inserted into the corresponding second jacks 21;

[0026] This enables the connector to be assembled through a fully plastic housing, reducing the electromagnetic interference at the terminal connection. By adding the assembly of the tails of the first terminal 3 and the second terminal 4 and adding the rear plug 2 to the wire soldering part, it ensures that the formed wire leaks glue into the connector.
