Description

Waterproof connector

Technical field

The invention belongs to the technical field of connectors, and in particular relates to a waterproof connector. Background technique

With the continuous development of science and technology, people's work and life are inseparable from electricity. In order to facilitate the use of electricity, people have created a variety of practical connectors. The connector is a connection device that connects multiple signal wires or power cables in sequence. The current connector structure design is not reasonable enough, and has the following disadvantages:

1. The seal between the connector and the connecting line tube is relatively poor, the waterproof effect is not good, and the outside water can easily enter the connecting line tube;

2. The connection between the male plug and the female plug is troublesome, and the disassembly is difficult. It takes not only a long time to complete, but also the electrical conductivity at the joint is lowered, that is, the resistance at the joint is large, resulting in voltage imbalance. In addition, the sealing between the male plug and the female plug is poor, the joint surface is left with a gap, and the waterproof effect is poor. It can only be used in a dry place. For example, when the electrical joint leaks outside, the water can easily be removed from the public. The gap between the plug and the female plug flows into the inside of the electrical connector, which is prone to short circuit, which may cause damage to the connector or cause leakage, which may endanger the safety of the consumer.

In the prior art, in an outdoor facility such as an LED guardrail tube or a digital tube, and a waterscape facility, a waterproof connector is required to connect to prevent water from penetrating into the connector component, causing the connector to rust. Short-circuit and cause failure. At present, most of them are screw-tight. When assembling, the male plug and the female plug need to be tightened by nuts to achieve the function of sealing waterproof and reliable connection. The sealing ring for waterproofing is generally set in The female plug port, if it is not inserted or tightened during docking, will not be waterproof. Summary of the invention

Dust performance, can be widely used in electrical and signal connections in the wild and harsh environments. This product has reached the dust-proof level 6, waterproof level 7 IPXX international protection standard, and has the functions of salt-proof and anti-corrosion. It is suitable for outdoor performances, especially in the outdoor performance during the rainy season, it can effectively prevent the rainwater from penetrating outside the node. The resulting sound-controlled deformation problem is also suitable for use in severe weather conditions, such as field training, offshore operations, etc., to provide support for the use of power and signal connections for combat troops under informatized conditions.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Example 1

As shown in Figs. 1 to 6, the waterproof connector comprises a base 1, a plastic pellet 2, a first punching member 3, a second punching member 4, and a sealing ring 5. The base 1 and the plastic pellet 2 are circular, and the base 1 is hollow. The plastic pellet 2 is cylindrical, and the plastic pellet 2 is accommodated in the base 1. The plastic pellet 2 is provided with three wiring holes. The sealing ring 5 is attached to the surface of the base 1 and has a good waterproof function. The first punching member 3 and the second punching member 4 abut each other and are disposed on the plastic pellet 2, wherein the first punching member 3 includes a hook 31 and a bent portion 32, and the hook 31 has two and are arranged side by side, the second punching member 4 includes a pressing portion 41 and a protrusion 42, and the bottom surface of the protrusion 42 is inclined, and the bottom surface of the protrusion 42 abuts against the bent portion 32 of the first punching member 3, since the protrusion 42 and the bent portion 32 pass through the inclined surface The abutting fit, so that once the artificial force is exerted on the pressing portion 41 and the second punching member 4 is moved downward, the protrusion 42 exerts a force on the bent portion 32, so that the first punching member 3 is integrally oriented to the plasticizing portion. 2 moves in the axial direction. A circular rubber ring 6 is further disposed in the base 1. When the male and female connectors are locked and locked, the outer contour of the male head cooperates with the rubber ring 6 disposed in the waterproof connector base 1, thereby effectively preventing water from penetrating into the male head. And within the female head.

Since the female end of the waterproof connector is engaged with the male head, the hook 31 of the first punching member 3 is engaged with the groove provided on the inner wall of the male head, thereby achieving the locking of the male and female fingers. When the locking state of the male and female heads needs to be untied, the pressing force is applied to the pressing portion 41 of the second punching member 4, and the pressing portion 4 is moved downward, and the projection 42 pushes the bent portion 32 at the same time. When moving in the horizontal direction, when the entire punch 3 is moved in the axial direction of the plastic pellet 2, the hook 31 is separated from the groove of the inner wall of the male head, so that the male and female heads can be smoothly unwound. Since the first punching member 3 and the second punching member 4 are both elastic pieces, once the pressing force applied to the pressing portion 41 of the second punching member 4 disappears, the first punching member 3 returns to elastic deformation. When the male and female heads need to be connected, the male and female heads are directly matched, and the hook 31 of the first punching member 3 can be easily fitted with the groove provided on the inner wall of the male head to realize the locking of the male and female heads. connection.

Example 2:

As shown in Figs. 7 to 8, the plastic pellet 2 is provided with four wiring holes.

Example 3:

As shown in Figs. 9 to 10, the plastic pellet 2 is provided with five wiring holes.

The waterproof connector of the invention adopts a button interior, the base 1 is formed at one time, and the base 1 is made of a combination of a zinc shell and a plastic material, and the sealing ring 5 is made of rubber material, which is convenient for assembly, and at the same time can achieve good waterproof and dustproof performance, Widely used in electrical and signal connections in the wild and harsh environments. This product has reached the dust-proof level 6, waterproof level 7 IPXX international protection standard, and has the functions of salt-proof and anti-corrosion. It is suitable for outdoor performances, especially in the outdoor performance during the rainy season, it can effectively prevent the rainwater from penetrating outside the node. The resulting sound-controlled deformation problem is also suitable for use in severe weather conditions, such as field training, offshore operations, etc., to provide support for the use of power and signal connections for combat troops under informatized conditions.

Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, and are not intended to be limiting; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that The technical solutions described in the embodiments are modified, or the equivalents of the technical features are replaced by the equivalents; and the modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
