Description

Technical Field

[0001] The utility model belongs to the field of electrical equipment, and in particular relates to a waterproof socket. Background Art

[0002] The waterproof socket is an electronic product developed to prevent water or moisture from penetrating into the socket. It includes a shell, a terminal seat arranged at the bottom of the shell, a female terminal assembly arranged in the terminal seat, and a shell cover hinged on the shell. The front end of the shell cover is provided with a lock that locks with the shell. Traditional locks are usually rotatably connected to the shell cover by a rotating shaft and reset by a torsion spring. There are disadvantages such as many parts, troublesome installation, high cost, and easy rust of torsion springs. In order to simplify the structure, there is currently a method of directly setting a spring on the lock on the market. However, there are still disadvantages: 1. The lock is easy to fall off from the shell cover and has poor stability; 2. The pressing feel is poor and the reset is not sensitive. Utility Model Content

[0023] Reference Figure 1-8 As shown, the IP66 waterproof socket of the utility model comprises a housing 1, a terminal seat 2 arranged at the bottom of the housing 1, a female terminal assembly 3 arranged in the terminal seat 2, and a housing cover 4 hinged on the housing 1. A lock buckle 5 is provided at the front end of the housing cover 4. The lock buckle 5 comprises a flat mounting portion 6, an unlocking button 7 integrally formed at the upper end of the mounting portion 6, and a lock hook 8 integrally formed at the lower end of the mounting portion 6. An upwardly inclined reset spring piece 9 and an inclined positioning shoulder 30 are integrally formed at both sides of the upper end of the mounting portion 6, and an upwardly inclined stop spring piece 10 is integrally formed at both ends of the lower end of the mounting portion 6. A mounting groove 11 for mounting the mounting portion 6 and a positioning groove 12 for positioning the reset spring piece 9 are provided at the front end of the housing cover 4. A stop step 13 for stopping the stop spring 10 is provided at the lower inner side of the installation groove 11, an inner convex rib 14 supporting the inner wall of the installation portion 6 and acting as a fulcrum is provided at the upper inner side of the installation groove 11, and an outer convex rib 15 supporting the outer wall of the installation portion 6 and acting as a fulcrum is provided at the upper outer side of the installation groove 11. The inner convex rib 14 and the outer convex rib 15 are arranged opposite to each other and are ideally located at the same horizontal plane. Under the support of the inner convex rib 14 and the outer convex rib 15, the lock buckle 5 rotates more smoothly and is not easy to get stuck. A lock groove 16 cooperating with the lock hook 8 is provided on the housing 1, and the positioning shoulder 30 is positioned at the end face of the installation groove 11. When the lock buckle is inserted into the installation groove of the shell cover, the stop spring is hung on the stop step to prevent the lock buckle from retreating; the reset spring is positioned in the positioning groove to prevent the lock buckle from moving left and right; the positioning shoulder abuts against the end face of the installation groove to prevent the lock buckle from falling.

[0024] Preferably, the inner wall of the mounting portion 6 is provided with an inner stop bevel 17 positioned at the inner convex rib 14, and the outer wall of the mounting portion 6 is provided with an outer stop bevel 18 positioned at the outer convex rib 15. The inner stop bevel 17 and the outer stop bevel 18 can further support and stop the lock buckle 5, thereby further improving the rotation stability of the lock buckle 5 and preventing it from falling off.

[0025] Preferably, the housing 1 is provided with a socket 19 at a position corresponding to the female terminal assembly 3, and a sealing plane 20 is provided on the top of the socket 19, and a sealing ring 21 is provided in the housing cover 4 to seal with the sealing plane 20, and after the housing cover 4 is covered on the housing 1, the sealing ring 21 applies pressure to the sealing plane 20, so as to achieve a waterproof effect at the socket 19, and the waterproof level can reach IP66 by adopting the above sealing method.

[0026] Preferably, the outer convex rib 15 is provided with an inclined surface 22, and the outer stop bevel 18 acts on the inclined surface 22. And under the elastic force of the reset spring sheet 9 and the stop spring sheet 10, the outer stop bevel 18 has a downward sliding force through the inclined surface 22, so that the lock buckle 5 can be more stably maintained in the installation groove 11.

[0027] Preferably, a semi-arc-shaped protective cover 23 covering the unlocking button 7 is integrally formed at the front end of the shell cover 4 corresponding to the upper side of the mounting groove 11 thereof, and a limiting surface 24 for limiting the unlocking button 7 after being pressed into place is provided in the semi-arc-shaped protective cover 23, and a limiting protrusion 25 is provided at the upper end of the unlocking button 7. This can effectively prevent the unlocking button 7 from being broken, and at the same time, the semi-arc-shaped protective cover 23 also plays a supporting role for the finger when unlocking, so as to facilitate pressing the unlocking button 7.

[0028] Preferably, the surface of the semi-arc-shaped sheath 23 is provided with anti-slip grooves 26 to prevent the fingers from slipping when supported.

[0029] Preferably, the housing 1 is provided with an installation opening 27, the installation opening 27 is provided with three asymmetrically arranged foolproof installation columns 28, and the seat cover of the terminal block 2 is provided with a foolproof positioning groove 29 that cooperates with the foolproof installation columns 28, so as to play a role in positioning and foolproofing the terminal block 2 during installation.

[0030] Preferably, the resetting spring sheet 9 has a greater elastic force than the stop spring sheet 10, so as to facilitate the quick resetting of the lock buckle 5 after being pressed.

[0031] Preferably, the surfaces of the reset spring sheet 9 and the positioning shoulder 30 are smoothly transitioned, so that the lock buckle 5 is smoother and more convenient to press.

[0032] The above does not limit the present invention in any form. Although the present invention has been disclosed as a preferred implementation case as above, it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modifications to the equivalent implementation cases of equivalent changes by using the above-disclosed structures and technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above implementation cases based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
