Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects of the connector with a detachable collar according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

Please refer to fig. 1-6, which are schematic structural diagrams of a connector with a readily detachable collar according to the present invention, the connector includes an outer housing 1 and a coupling nut 2 rotatably assembled outside the outer housing, a locking assembly and a collar 4 disposed between the outer housing 1 and the coupling nut 2 and limiting an axial movement space of the locking assembly to a tail portion of the coupling nut. The clamping ring 4 is sleeved on the outer shell 1 and axially limited with the outer shell 1, and the outer peripheral surface of the clamping ring 4 is in clearance fit with the inner peripheral surface of the connecting nut. Because the clamping ring is assembled in place, the tail part of the clamping ring is flush with the tail part of the connecting cap, and only one side surface of the whole part is exposed, when the clamping ring needs to be reworked and repaired, the clamping ring is damaged and is inconvenient to take out. The inner side of the tail part of the connecting nut 1 is also provided with a slot 8, the slot 8 and the peripheral surface of the clamping ring enclose a space for inserting a clamping ring taking and disassembling tool, a sharp tool or a screwdriver and the like can be used for extending into the slot at the tail part of the connecting nut to damage the clamping ring, then the clamping ring is taken out, and further the product is reworked or repaired.

In the embodiment of the present invention, the number of the slots is three, but not limited to, the slots are evenly distributed along the circumference of the coupling nut. After the clamping ring is assembled in place, gaps are reserved at the three grooves of the clamping ring, and the grooves do not influence all functions of the clamping ring.

The slot is rectangular in shape or other shape that can form a gap with the collar for insertion of a removal tool.

In the embodiment of the invention, the inner ring of the clamping ring 4 is provided with claws 12 which are matched with the annular grooves 11 on the outer shell for positioning. The shape of the claw includes but is not limited to a rectangle and a sheet type extending structure satisfying a cantilever beam structure. When the clamping ring is assembled, the clamping ring firstly passes through the thread part at the tail part of the outer shell, the clamping jaws extending out of the inner ring of the clamping ring are stressed and compressed, the clamping ring is sleeved in the threads and continuously moves until the clamping jaws reach the outer ring groove of the outer shell, the clamping jaws rebound to clamp the bottom surface of the ring groove, and at the moment, the clamping ring cannot fall off.

In another embodiment of the invention, the anti-loose component achieves the anti-loose purpose through a clamp spring 3 assembled in an annular groove in the connecting nut 2, and the clamping ring 4 is supported on the inner periphery of the clamp spring 3 to prevent the clamp spring from being radially deformed and separated from the connecting nut. Preferably, the outer periphery of the front end of the retainer ring 4 contacts the inner peripheral surface of the clamp spring to prevent the clamp spring from deforming inward and separating from the connecting nut, and the front end surface of the retainer ring is in stop fit with the anti-loosening assembly to realize the reinforced stop of the anti-loosening assembly, but the invention is not limited thereto.

Preferably, the periphery of the retainer ring 4 is in a step shape with a small front part and a large rear part, wherein the small-diameter end extends into the inner ring of the clamp spring to prevent the clamp spring from shrinking and ensure that the clamp spring cannot be separated, so that the function of preventing the clamp spring from loosening is realized, and the front end surface of the clamp spring is in blocking fit with the anti-loosening assembly to enhance axial limit. After the retainer ring 4 is assembled in place, the front end part of the retainer ring extends into the inner ring of the clamp spring.

In the embodiment of the invention, the anti-loosening assembly comprises a locking washer 5, a corrugated spring 6 and a triple-key retainer ring 7 which are sequentially matched between an outer shell 1 and a connecting nut 2 from front to back, wherein the outer periphery of the outer shell 1 is provided with an annular boss, the front end face of the annular boss is matched with the inner step face of the connecting nut in a stop manner, the rear end face of the annular boss is matched with the front end face of the locking washer 5 in a stop manner, the rear end face of the annular boss is provided with a groove matched and locked with a bulge 13 on the front end face of the locking washer 5, one side of the groove is a locking limiting part with a larger gradient for preventing the bulge 13 of the locking washer from passing over, and the other side of. And convex keys matched with key grooves in the connecting nut to realize circumferential rotation stopping with the connecting nut are arranged on the outer peripheral surfaces of the locking washer 5 and the three-key retainer ring 7.

The clamp spring 3 is stopped at the rear end of the triple-key retainer ring 7, so that the lower part of the front end of the triple-key retainer ring 7 is in stop fit with the step surface on the outer shell 1, and the axial sliding space of the anti-loose assembly is limited. The corrugated spring 8 is clamped between the locking check ring and the three-key check ring 7 and rotates along with the washer and the check ring when the connecting nut rotates, so that the front end face and the rear end face of the corrugated spring do not rotate relative to the check ring in contact with the front end face and the rear end face of the corrugated spring, and abrasion of the front end face and the rear end face of the corrugated spring is avoided. The front end of the retainer ring 4 extends into the inner ring of the clamp spring 3 to prevent the retainer ring from shrinking and falling off, and the front end face is blocked on the rear end face of the triple-key retainer ring 7, so that the anti-loosening assembly is blocked and strengthened.

In the embodiment of the invention, the outer peripheral surfaces of the locking washer and the three-key retainer ring are respectively provided with three convex keys, the tail part of the connecting nut is provided with three matched key grooves, and the locking washer and the three-key retainer ring are assembled according to the guidance of the key grooves.

In other embodiments of the invention, one or more convex keys are arranged on the outer peripheral surfaces of the locking washer and the triple key retainer ring.

When the nut took place to rotate, can drive three key retaining ring and lock washer through keyway cooperation nut and rotate simultaneously, the recess that the lock washer arch breaks away from the shell body this moment, and corrugated spring takes place the compression this moment, provides the locking force, but its and lock washer can take place to rotate simultaneously with the three key retaining ring, can not produce the friction.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention has been disclosed with the preferred embodiment, it is not limited to the present invention, and any skilled person in the art can make modifications or changes equivalent to the equivalent embodiment of the above embodiments without departing from the scope of the present invention, but all the modifications, changes and modifications of the above embodiments by the technical spirit of the present invention are within the scope of the present invention.
