DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings of the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0027] Embodiment one

[0028] Reference Figures 1-4 A rectangular connector, comprising:

[0029] Female plug 1 and male plug 2, wherein male plug 2 is designed to be detachably inserted into female plug 1, and the bottom of female plug 1 is equipped with first cover 101 for covering and protecting female plug 1 and the wire harness connected thereto, and correspondingly, the top of male plug 2 is equipped with second cover 201 to protect male plug 2 and the wire harness connected thereto in the same way.

[0030] In order to enhance the stability of the connection, a locking mechanism is provided, which is installed on the first cover 101 and the second cover 201, and its main function is to lock the wire harness connected between the female plug 1 and the male plug 2, thereby effectively preventing the wire harness from being disconnected from the connector when subjected to external force pulling, ensuring the safety and reliability of the connection.

[0031] The locking mechanism mainly consists of a connecting seat 3, a clamping frame 4, a trapezoidal block 5, a tension spring 6, a trapezoidal frame 8 and a knob 7, etc. The connecting seat 3 is fixedly provided on the first cover 101 and the second cover 201 respectively, and a plurality of clamping frames 4 are slidably embedded in the inner ring of the connecting seat 3. The number of clamping frames 4 is determined according to actual needs to fully clamp the wire harness. The inner side of each clamping frame 4 is connected to the inner ring of the connecting seat 3 through the tension spring 6, which provides an inward elastic force for the clamping frame 4, so that the clamping frame 4 can be accommodated in the inner wall of the connecting seat 3 when there is no wire harness. The number of trapezoidal blocks 5 is the same as that of clamping frames 4 and they are connected together. They are slidably arranged in the inner part of the connecting seat 3. The trapezoidal frame 8 is slidably arranged at the bottom of the connecting seat 3 and is in close contact with the hypotenuse of the trapezoidal block 5. When the knob 7 is rotated, the trapezoidal frame 8 will move upward along the threads of the connecting seat 3 and push the trapezoidal block 5 to slide, and the movement of the trapezoidal block 5 will further push the clamping frame 4 to clamp the wire harness inward.

[0032] In addition, in order to increase the clamping effect, a plurality of anti-skid rubber blocks 401 are fixedly arranged on the side of the clamping frame 4 close to each other. These rubber blocks 401 can increase the friction between the wire harness and the clamping frame 4, ensuring that the wire harness is clamped firmly.

[0033] The present application can be used in the technical field of rectangular connectors with self-locking structure, and can also be used in other fields applicable to the present application.

[0034] Embodiment two

[0035] Based on embodiment one, embodiment two further comprises: a rectangular connector with a self-locking structure, which is applied to the technical field of rectangular connectors with a self-locking structure. Flexible plates 9 are fixedly arranged on both sides of the male plug 2, and clamping blocks 10 are fixedly arranged on the flexible plates 9. Correspondingly, clamping grooves 11 adapted to the clamping blocks 10 are formed on both sides of the female plug 1. When the male plug 2 is inserted into the female plug 1, the flexible plates 9 will drive the clamping blocks 10 to move inward, so that the male plug 2 can smoothly enter the female plug 1. When the clamping blocks 10 reach the position of the clamping grooves 11, the elastic restoring force of the flexible plates 9 will push the clamping blocks 10 to move outward and be clamped into the clamping grooves 11, thereby realizing the stable insertion between the male plug 2 and the female plug 1.

[0036] The two sides of the female plug 1 are fixedly provided with buckling racks 12, and the two sides of the first cover 101 are fixedly provided with buckling blocks 13 matched with the buckling racks 12.

[0037] The sealing ring 16 is fixedly arranged on the first cover 101 and the second cover 201 close to the female plug 1 and the male plug 2, and when the covers are buckled on the female plug 1 and the male plug 2, the sealing ring 16 is tightly combined with the corresponding parts of the female plug 1 and the male plug 2, thereby effectively preventing external impurities such as dust and moisture from entering the female plug 1 and the male plug 2, and ensuring the normal work and service life of the female plug 1 and the male plug 2.

[0038] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
