The elastic sealing gasket 23 is of an oblong annular structure and is made of elastic rubber material, a penetrating through hole 231 for the metal socket 81 of the male head to penetrate is formed in the middle of the elastic sealing gasket 23, and positioning keys 232 are arranged on the two opposite side walls of the elastic sealing gasket in a radially outward protruding mode; correspondingly, a positioning hole 2221 is formed in each extending portion 222, and the positioning holes can be through holes and are used for being matched with positioning keys to realize installation and fixation of the elastic sealing gasket. As shown in fig. 18, an elastic sealing pad 23 is placed at the front end of the inner cavity. The elastic sealing gasket 23 can be in sealing fit with the metal socket 81 of the male on one hand; on the other hand, the plug can be provided with a reaction force opposite to the plugging direction when the head seat is plugged so as to maintain a stable locking state, and the function is described in detail later.
Further, a radially extending flange 224 is further provided on the outer wall of the support 22, and the flange 224 is disposed near the front end of the support and is located at the outer periphery of the anti-rotation flat. The flange 224 is used for being in stop fit with a stop 192 arranged on the inner wall of the connecting cap 19 in the axial direction so as to realize forward limit of the connecting cap assembly; after the compression nut is in screwing fit with the threaded portion, the compression nut can limit the backward direction of the connecting cap assembly. Therefore, the connecting cap assembly can be movably arranged on the support frame along the axial direction and can radially rotate relative to the support frame assembly.
The plug and socket insertion process in the invention is as follows:
Firstly, aligning a built-in male head of a plug with a built-in female seat of a socket, and then inserting the plug to enable the male head and the female seat to be inserted. And then the connecting cap assembly of the plug end is pushed forwards and rotated clockwise by a certain angle, so that the clamp nail moves along the guide inclined plane of the socket shell, and after passing through the highest point, the clamp nail falls into the lowest point, thereby realizing quick locking. At this moment, the sealing gasket just receives the axial pressure of socket casing preceding terminal surface, has realized on the one hand that the head seat is to the sealing function after inserting, on the other hand, the sealing gasket has provided the reaction force who deviates from the direction of inserting for the plug for the staple firmly clamps the minimum point department of arranging the draw-in groove in, and the staple falls into the locked groove promptly, under high frequency vibration environment, avoids the staple to cross the highest point and get back to on the guide inclined plane, can prevent that the headstock from unblock easily.
In this embodiment, the two ends of the header are designed based on the shape of the existing TYPEC-port connector, for example, the section of the receiving slot of the socket housing is oblong, and the inner cavity of the support frame of the header is also an oblong cavity structure matched with the existing male header; in other embodiments, structural transformations may also be performed, e.g., designed to fit the corresponding structure of a common Microusb interface.
In the embodiment, two clamping grooves are formed, and two clamping nails are correspondingly formed; in other embodiments, only one or more than three clamping grooves may be provided, but it should be noted that if three or more than three clamping grooves are provided, the clamping grooves should be ensured to be on the same circumference, the arrangement positions of the clamping nails should be ensured, and the rotation strokes of the clamping nails screwed into the corresponding clamping grooves are consistent, so that synchronous locking of a plurality of clamping nails can be realized.
