Technical field

The utility model relates to the field of sockets, in particular to a firm safety socket.

Background technique

Socket, also known as power socket, switch socket. Socket refers to a socket into which one or more circuit wiring can be inserted, through which various wiring can be inserted. This facilitates connection with other circuits. Through the connection and disconnection between the circuit and the copper piece, the final connection and disconnection of this part of the circuit is achieved.

With the popularity of sockets, people are slowly discovering that existing sockets have some safety hazards. For example, when the plug in the socket is unplugged, it is easy to pull out the entire panel, causing the socket to collapse, bare metal or even electric shock; in addition, when a person is tripped by a wire when passing by, it will cause great force on the socket for a short time. In addition, the force will pull the socket panel from the side and easily pull the socket panel from the base, which poses a serious safety hazard.

detailed description

In order to facilitate the understanding of those skilled in the art, the present utility model will be further described in detail below in conjunction with specific embodiments and drawings.

Please refer to Figures 1-9, the embodiments of the present invention include:

A solid safety socket, comprising a base 1 and a socket panel. The socket panel includes a cover 2 mounted on the base 1 and a cover 3 arranged between the base 1 and the cover 2. The cover 3 is provided There is a socket 4; wherein the cover 3 is snap-connected with the base 1; a male buckle 5 is provided on the cover 3, and the male buckle 5 includes a plate body 6 that is not elastic and has a block shape and is arranged on the plate body 6. A locking strip 7 with no elasticity at the end, a female buckle 8 matched with a male buckle 5 is provided on the base 1. The female buckle 8 includes a window 9 excavated on the base 1 and fixed at the window 9 In addition, there is an elastic horizontal plate 10, the horizontal plate 10 and the inner wall of the window 9 enclose a gap 11, the plate body 6 is inserted into the gap 11, and the locking strip 7 and the horizontal plate 10 are mutually abutted. The locking strip 7 protrudes from the board 6. The horizontal plate 10 can change the size of the gap 11 within its own elastic deformation range; when the horizontal plate 10 does not undergo elastic deformation, the total thickness of the locking strip 7 and the plate body 6 is greater than the gap 11, and the locking strip 7 cannot be inserted at this time Into gap 11. The locking strip 7 is provided with a curved surface 12 which is convenient for the male buckle 5 to be inserted into the gap 11. The locking strip 7 is provided with a locking surface 13 perpendicular to the plate body 6 at a position away from the arc surface 12 and used to prevent the male buckle 5 from leaving the gap 11. The gap 11 enclosed by the horizontal plate 10 and the inner wall of the window 9 gradually narrows with the direction in which the male buckle 5 is buckled. The horizontal plate 10 is provided with a recess 14 which is mutually abutted with the locking strip 7. A male buckle 5 and a side wall 15 enclosed in a circle are provided at the peripheral edge of the cover 3, and a reinforcing rib 16 is connected between the plate body 6 and the side wall 15. The side wall 15 is kept perpendicular to the surface where the insertion hole 4 on the cover 3 is located, the plate body 6 is also vertical to the surface where the insertion hole 4 on the cover 3 is located, and the side wall 15 half surrounds the male buckle 5. The number of male buckles 5 is four, and they are evenly distributed on the two long sides of the cover 3, the number of female buckles 8 is also four, and the positions of the male buckles 5 and female buckles 8 correspond one by one.

The working principle is as follows: the male buckle and the female buckle are locked with each other, thereby locking the cover and the base by the buckle. Specifically, the male buckle does not have elasticity. The male buckle has two parts: a plate body and a locking bar. The female buckle is formed by the opening on the base and the horizontal plate on the opening. The horizontal plate and the inner wall of the opening form a gap. , Where the locking bar is at the edge of the end of the board. Before the cover and the base are not locked, the horizontal plate does not undergo elastic deformation. The width of the end with the locking bar on the board is greater than the gap width. The male buckle can be inserted into the gap by applying force. When inserting, the cross plate and the arc on the lock bar conflict, and the cross plate is elastically deformed under the force of the arc, and the gap width becomes larger at this time; When it becomes large enough, the plate is completely inserted into the gap. At this time, the locking surface of the locking strip and the recess on the horizontal plate are snap-locked to each other, so that the cover and the base are locked and locked firmly. After the cover is locked with the base, if it is necessary to separate the cover from the base, move the horizontal plate placed horizontally in the window to deform the horizontal plate, and then the male can be buckled by increasing the gap width. Separate from the female buckle; otherwise, the cover can be separated from the base only by violently destroying the male buckle or the female buckle. At the same time, since the contact surface of the male buckle and the female buckle is thicker, the contact surface is the thickness of the locking strip The longitudinal thickness of the horizontal plate is relatively thick, so that the male buckle and the female buckle bear a lot of force and are not easily damaged. Therefore, the connection strength of the male buckle and the female buckle in this embodiment is very high, which can ensure that the socket panel is extremely difficult to separate from the base due to external forces, and the socket has high firmness and safety.

Although the description of the present invention is made in conjunction with the above specific embodiments, it is obvious that those skilled in the art can make many substitutions, modifications and changes based on the above content. Therefore, all such substitutions, improvements and changes are included in the spirit and scope of the appended claims.
