Technical Field

The invention relates to electrical plug connector and module with new type dust-proof shutter mechanism & electrical plug connector module.

Background Technology

The electrical plug connector is used to establish an electrical connection between the first cable and the second cable, or is also used to establish an electrical connection between the first cable and the electrical appliance, to prevent the dust enter into the electrical plug connector and causing poor connection, thus, a dust-proof shutter structure will be added, some dust-proof shutter structures are non-rotating, plug in and out are complicated. To solve this problem, the Chinese invention patent with application publication number CN 103-135183 A and application publication date of 2013.06.05 discloses an optical fiber connector with a dust-proof shutter structure, which discloses that the dust-proof shutter can directly plug in through the setting of elastic elements, but when plug out, the dust-proof shutter will bounce out of the docking space where the dust-proof door is installed due to the elastic element, the dust-proof effect is not good.

Content Of Invention

In order to overcome the above-mentioned shortcomings, the object of the present invention is to provide an electrical plug connector and module with new type dust-proof shutter mechanism, which will not protrude from the window and not easy to bounce out of the docking space/window, and the dust-proof effect is good.
In order to achieve the above object, the technical solution adopted by the present invention is: an electrical plug connector and module with new type dust-proof shutter mechanism, comprising an electrical plug connector slot body, a window installed on the slot, and the dust-proof shutter mechanism installed inside the window, the dust-proof shutter mechanism comprising a dust-proof shutter and a torsion spring, the clamping column installed on opposite sides in the window for rotating the lower end of dust-proof shutter, and an embedded torsion spring groove installed at the side of dust-proof shutter, a torsion spring fixed point installed on the inner wall of torsion spring groove, torsion spring sleeve installed on the torsion spring fixed point, dust-proof shutter installed on the dust-proof shutter clamping column by rotating the torsion spring ,the direction of rotation is inside the window, the window is closed type window, the closed type window complete cover dust-proof shutter mechanism, the dust-proof shutter is provided with a limited structure to prevent the dust-proof shutter from being bombarded.
The good effect of this invention for electrical plug connector & module with new type dust-proof shutter mechanism is, the window is closed type to completely cover the dust-proof shutter mechanism, to prevent dust enter into the window, and the limited structure protect the dust-proof door from turning out, so that the dust-proof door will not protrude from the window and it is not easy to rebound out of the docking space /window, good dust-proof effect.
Preferably, the limit structure does not require an extra additional structure, only need to set the position of limited structure and structure.

As the dust-proof shutter is turned inward, when the dust-proof shutter rotates to the inside around the dust-proof shutter clamping column, the arc structure on the inner side of the dust-proof shutter will not hinder the rotation of the dust-proof shutter, and the torsion spring is in a compressed state; When the plug is withdrawn, the elastic force released from the torsion spring will push the dust-proof shutter pop out. When the inner frame of the window touches the right angle structure, the rotation of the dust-proof shutter is restricted. In the specific implementation, it is necessary to ensure that the gap between the right angle structure of the dust-proof shutter and the inner frame of the window is small, and the value range of the tiny gap is not required. The value range only needs to be guaranteed: when the right angle structure of the dust-proof shutter touches inner frame of the closed type window, the dust-proof shutter is limited in the closed type window, and will not pop up due to elastic force.

The rear of the separated pothook is provided with a fixed chute, and the mouth of the fixed chute is provided with a limited pothook, and the opening of the fixed chute is an eight-character groove that is convenient for the sliding of the limited fixing clamping column. The setting of eight-character groove makes it convenient for the limit fixing clamping column to be introduced into the fixed chute. During installation, the separated pothook is clamped in place by the side extension limit fixing clamping column, and the limit pothook at the opening of the fixed chute will fix the limit fixing column, so that the pothook is completely fixed to the shielded slot, and will not fall off due to external force.
