Detailed Description

To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

The embodiment provides a connector with a bidirectional unlocking function, referring to fig. 1, fig. 2 and fig. 5, the connector includes a male plug 1 and a female plug 2 which can be plugged and matched, the male plug 2 further includes an unlocking ring 23 with a cylindrical structure, the plugging end of the male plug 1 and the female plug 2 is taken as the front end, the unlocking ring 23 is sleeved on the shell of the male plug 2 and can slide back and forth along the front-back direction, an elastic buckle 21 is fixedly arranged on the male plug 2, a through groove 233 for exposing the hook-shaped head of the elastic buckle 31 is arranged on the unlocking ring 23, a buckle locking groove 11 is arranged in the shell of the female plug 1, and when the male plug 2 is butted with the female plug 1, the buckle locking groove 11 is clamped with the elastic buckle 21 on the male plug 2 to form locking; when the unlocking ring 23 is slid backward during unlocking, the through groove 233 abuts against the inclined surface of the hook-shaped head of the elastic buckle 21, and the elastic buckle 21 is pressed inward to unlock the buckle locking groove 11.

As can be seen from the above, when the male and female are inserted and unlocked, the unlocking ring 23 needs to be driven to slide backwards, and for applying force, the present embodiment is provided with an operating mechanism for driving the unlocking ring 23 conveniently, which includes the operating ring 24, referring to fig. 5 and 6, which shows the specific structure of the unlocking ring 23 and the operating ring 24, the unlocking ring 23 is provided with a slot 232 arranged along the circumferential direction thereof, the operating ring 24 is provided with a first step 242 therein, and referring to fig. 4, the first step 242 is clamped in the slot 232, the operating ring 24 is provided with a second step 243 at the rear end thereof, the second step 243 forms a reducing part, the second step 243 forms a limit for the forward movement of the operating ring 24 after the operating ring 24 is assembled on the shell of the male plug 2, the rear end of the unlocking ring 23 is provided with a compression spring 22, the compression spring 22 is in a compressed state, thereby always giving the unlocking ring 23 a forward driving force, while also providing a reset force to reset the unlocking ring 23 when the unlocking ring 23 is moved backward. In order to facilitate the installation of the operating ring 24, referring to fig. 7, the operating ring 24 may be configured as a split structure, and when installed, the split structure is engaged and assembled on the male plug 2 from two radial sides of the male plug 2.

The unlocking ring 23 has an unlocking groove 231, and with continued reference to fig. 5, the unlocking groove 231 is a hook-shaped groove disposed on the outer periphery of the unlocking ring 23, and is formed by joining a first unlocking groove 2311 which is substantially bent backward and a second unlocking groove 2312 which is substantially sloped in the circumferential direction; the operating ring 24 is a barrel-shaped structure, and referring to fig. 4 and 6, the front end of the operating ring 24 is sleeved on the unlocking ring 23, the unlocking roller 241 is arranged in the cavity of the operating ring 24 corresponding to the unlocking groove 231, when the operating ring 24 and the unlocking ring 23 are assembled together, the unlocking roller 241 is located in the unlocking groove 231, under the forward elastic restoring force of the compression spring 22, the unlocking ring 23 is pushed forward, and the unlocking roller 241 is tightly abutted against the first unlocking groove 2311 in the shape of a curved recess, so as to form a locking position, then:

1. since the unlocking roller 241 is tightly attached to the first unlocking groove 2311, and the operating ring 24 is pulled backwards, the operating ring 24 can drive the unlocking ring 23 to slide backwards through the interference effect of the unlocking roller 241 and the first unlocking groove 2311, so that the male and female connectors are unlocked;

or:

2. when the operating ring 24 is twisted in the circumferential direction, the unlocking roller 241 can roll relatively to the top of the slope of the second unlocking groove 2312 (or may not reach the top of the slope) by being guided obliquely by the second unlocking groove 2312 in a slope shape, and the unlocking ring 23 slides relatively backward, so that the male and female connectors are unlocked.

When the unlocking ring is reset, the unlocking ring 23 is driven to reset through the forward elastic restoring force of the compression spring 22, and in the case 1, the operating ring 24 and the unlocking ring 23 are synchronously reset in a front jacking mode; in case 2, the unlocking ring 23 is reset by the front top, and the manipulation ring 24 is reset by the rolling guide of the second unlocking groove 2312.

In order to improve the reliability and stability of unlocking, the unlocking rollers 241 and the unlocking grooves 231 are symmetrically arranged in two groups at 180 °. To ensure stability of the unlocking roller 241 being caught in the first unlocking groove 2311, the shape of the unlocking roller 241 substantially matches the curved concave shape of the first unlocking groove 2311.

The matching structure of the operating ring 24 and the unlocking ring 23 in the embodiment provides two unlocking modes of driving the unlocking ring 23 to slide backwards in the circumferential direction and the axial direction, and in particular, an appropriate operation scheme can be selected according to the situation, and the required torsion is smaller and the operation is more appropriate due to the fact that the circumferential unlocking mode is provided with the rolling matching surface formed by the unlocking roller 241 and the second unlocking groove 2312.

In this embodiment, a circumferential unlocking mechanism is formed by the rolling fit of the unlocking roller 241 and the inclined guide surface of the second unlocking groove 2312, but the fit of the unlocking roller 241 and the second unlocking groove 2312 may be replaced by a sliding fit, for example, the unlocking roller 241 may be replaced by a fixed cylinder structure, and when the operating ring 24 is twisted, the cylinder structure is guided by the second unlocking groove 2312 to slide obliquely to the top of the second unlocking groove 2312, so as to achieve the same technical effect.

In order to facilitate the application of force to the operating ring 24, a handle may be connected to the operating ring 24, or a concave-convex pattern may be formed to form a force application portion, which facilitates the operation.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
