Blade type waterproof connector

Abstract

The invention relates to a knife switch-type waterproof connector, which comprises a first connecting piece and a second connecting piece. The first terminal of the second connecting piece and the second terminal of the second connecting piece are mutually connected to form electric conduction; a base is formed at one end of the second connecting piece; a frame body is convexly arranged on the base; an accommodating space is defined by the frame body; buckling grooves are symmetrically formed in two opposite edges of the frame body; the second terminal is convexly provided with a pin towards the direction of the accommodating space; a cover plate is arranged in the accommodating space; the two ends of the cover plate are respectively provided with buckling blocks in a protruding mode, andthe buckling blocks are used for buckling the buckling grooves; the outer periphery of the cover plate is concaved inwards to form a first padding groove; a gap formed in the first padding groove is filled and sealed with a hot melt adhesive layer; and the periphery of the pin is filled with the hot melt adhesive layer in a sealed mode. Therefore, the knife switch-type waterproof connector has theadvantages of being easy to assemble and effective in waterproof effect.

Description

technical field [0001] The invention relates to a connector for a circuit, in particular to a knife-type waterproof connector which is easy to assemble and effectively waterproof. Background technique [0002] When various electronic devices need to be connected to various circuits such as power supply or signal, it is common to fix the male end connector and the female end connector at both ends of the wire, and then quickly insert the male end connector and the female end connector. However, the connector is a part where the overall circuit is relatively prone to failure due to water immersion or moisture. Many electronic devices are used outdoors, in humid or in environments with large temperature changes, and even in a state of motion. For electronic equipment, this type of connector has very high requirements for waterproof function, and the stability of its electrical connection is also one of the main requirements.

[0002] When various electronic devices need to be connected to various circuits such as power supply or signal, it is common to fix the male end connector and the female end connector at both ends of the wire, and then quickly insert the male end connector and the female end connector. However, the connector is a part where the overall circuit is relatively prone to failure due to water immersion or moisture. Many electronic devices are used outdoors, in humid or in environments with large temperature changes, and even in a state of motion. For electronic equipment, this type of connector has very high requirements for waterproof function, and the stability of its electrical connection is also one of the main requirements. Many companies have developed connectors with waterproof function. The waterproof connector is usually in the shell A gasket or gasket is installed at the connection with the outer cover to block the gap formed at the connection, so that the outside and inside of the connector form a basic barrier and waterproof effect, but it is not difficult to find that the above-mentioned known structure still exists. There are some deficiencies, the main reasons are as follows: the spacer or gasket is first placed inside the connector, and the cover is assembled on the shell in a locked manner, so that the cover can fit the shell Clamp the spacer or washer, but when locking the outer cover, the pressing force generated by the force application point and the non-force application point are often different, resulting in the spacer or washer not being flatly clamped in the connector. The gap generated by flattening will reduce the waterproof effect of the connector. Moreover, even if it is tested to meet the waterproofness required by the connector after assembly, the gasket or gasket will be damaged after long-term use or thermal expansion and contraction. It is still possible that the gasket or gasket loses its waterproof function due to factors such as elastic fatigue or shrinkage. At the same time, this assembly method also has a large number of steps. During assembly, the defect rate will be increased and the waterproofness will be reduced because the relative position is not easy to fix. Therefore, The known connectors have long-term technical problems such as difficult assembly and insufficient waterproof effect
