Description

Waterproof connector with stop structure

This creation is related to waterproof connectors, and in particular to a waterproof connector having a stop structure.

Various electronic products can be transmitted and received to each other through connectors. Therefore, connectors have been widely used in the computer industry and home movie sound devices. Users can transmit the required data or signals through the settings of the connectors. .

In general, electrical products are exposed to electric current in outdoor or in a humid air environment, which may cause damage to electrical products. Therefore, the waterproof structure of the connector is particularly important.

Moreover, factors affecting the electrical conduction of the connector, in addition to the waterproof structure, the other reason that the connector is more likely to be damaged is that the external force at the time of docking is excessive. When a pair of plugs are inserted into the connector, since the insertion distance cannot be known, when the plug is inserted, it is easy to excessively apply force to push the inside of the connector, thereby causing damage to the insulating base or the conductive terminal, thereby affecting the electrical conduction of the connector. quality.

In view of this, in order to improve and solve the above-mentioned shortcomings, the creator has devoted himself to researching and cooperating with the application of theory, and finally proposed a creation that is reasonable in design and effective in improving the above-mentioned defects.

One of the aims of the present invention is to provide a waterproof connector with a stop structure to prevent damage to the inside of the connector due to excessive pushing during plugging, thereby maintaining the electrical conduction quality of the connector.

In order to achieve the above object, the present invention is a waterproof connector with a stop structure for plugging a mating connector. The waterproof connector includes an insulating base and a metal housing. The insulating base comprises a base and a tongue extending forward from the base, and the opposite sides of the base respectively have positioning recesses. The metal casing cover is sleeved on the outside of the insulating seat, and the opposite inner wall surfaces of the metal casing are respectively formed with positioning protrusions inwardly, and the positioning protrusions are disposed corresponding to the positioning concave areas, and are abutted on the positioning concave areas; wherein, the docking After the connector is inserted into the waterproof connector for a certain distance, the docking connector is resisted by the positioning bumps and can no longer continue to extend inward. Another object of the present invention is to provide a connector having a stopper structure, which is provided with a waterproof gasket on the outer edge surface of the metal casing, and covers the outer casing of the waterproof gasket, thereby external water and water. The gas does not penetrate between the outer casing and the metal casing.

Compared with the prior art, the present invention is to provide a positioning concave area on the base of the insulating base. In addition, the metal shell of the cover outside the insulating seat is correspondingly formed with positioning protrusions. When the metal casing is sleeved with the insulating seat, the positioning protrusions are abutted on the positioning recess. When the docking connector is inserted into the waterproof connector for a certain distance, the docking connector is resisted by the positioning bumps and can no longer continue to extend inward. According to this, the waterproof connector is not damaged by the excessive extrusion of the mating connector, thereby maintaining the proper electrical connection effect.

The detailed description and technical content of the present invention are described below with reference to the drawings, but the drawings are only for reference and explanation, and are not intended to limit the creation.

Please refer to the first to third figures, which are respectively an exploded perspective view, a stereoscopic appearance view and a combined sectional view of the waterproof connector with the stop structure. The waterproof connector 1 of the present invention has a heat insulating connector 1 including an insulating base 10, a metal casing 20 and a waterproof gasket 30. The metal casing 20 is sleeved outside the insulating base 10. The waterproof gasket 30 is sleeved on the outer edge surface of the metal casing 20 to prevent external water and moisture from penetrating, thereby providing waterproofing effect.

The insulating base 10 includes a base 11 , a tongue 12 extending forward from the base 11 , and a gasket 13 . The opposite sides of the base 11 respectively have a positioning recess 131. In an embodiment of the present invention, the gasket 13 is positioned on the gasket 13 . The locating recess 131 has a semi-circular cross section, but is not limited thereto.

The metal casing 20 is sleeved outside the insulating base 10, and the metal casing 20 has a front side port 201 and an opposite rear side port 202. The two inner wall surfaces of the metal housing 20 are respectively formed with a positioning protrusion 21 inwardly, and the position and shape of the positioning protrusion 21 are disposed corresponding to the positioning of the concave area 131. In an embodiment of the present invention, the positioning bump 21 has a semi-circular shape corresponding to the concave portion 131.

It should be noted that the positioning protrusions 21 of the metal casing 20 are formed by punching. Therefore, the opposite outer wall surfaces of the metal casing 20 are formed at a corresponding position of the positioning protrusion 21 with a recess 22 that does not communicate with the inside of the metal casing 20. When the metal housing 20 is sleeved on the insulating base 10, one side of the positioning protrusion 21 is used as a stop when the other connector is inserted, and the other side of the positioning protrusion 21 is Abutting on the gasket 13 further increases the adhesion between the metal casing 20 and the susceptor 11. In addition, the metal casing 20 of the present invention does not cause holes when the positioning protrusions 21 are formed, so that the metal casing 20 has better waterproofness.

Moreover, the waterproof connector further includes a plurality of conductive terminals (not shown). The waterproof connector 1 is a connector of a universal serial bus (USB), but the actual implementation is not limited thereto. In this embodiment, a bottom surface of the metal casing 20 has a plurality of pins 23 . Preferably, the gasket 13 is coupled to the front edge of the base 11, and the positioning protrusion 21 abuts the gasket 13 and is adjacent to the rear side port 202 of the metal casing 20.

The waterproof gasket 30 is sleeved on the outer edge surface of the metal casing 20. In an embodiment of the present invention, the outer peripheral surface of the waterproof gasket 20 is formed with a plurality of annular ribs 31 which are arranged in parallel and at intervals.
