Description

Technical Field

[0001] The utility model belongs to the technical field of sockets, and in particular relates to a fool-proof SN socket. Background Art

[0002] With the development of economy and the improvement of people's living standards, the number of electrical appliances in each household is increasing. Sockets are widely used in today's production and life, and are often used as electrical connectors to power electrical appliances. In order to ensure the stable transmission of electrical signals, once the sockets are plugged in during the production and assembly process, they are not allowed to be forcibly separated by external force. However, the existing sockets do not have a locking structure to maintain the plugged in state. After plugging in, the sockets are easily separated under the action of external force. In addition, during the assembly process, the plastic shell and the socket are easily reversely inserted due to negligence, which will cause damage to the conductive terminals in the socket and even cause electrical damage. Therefore, there is an urgent need for a fool-proof SN socket to solve the above problems. Utility Model Content

[0003] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a fool-proof SN socket.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0005] A fool-proof SN socket comprises a base, a mounting groove is provided on the front side of the base, pins are installed on both sides of the inside of the mounting groove, the other side of the pin passes through the base and extends to the outside thereof, an fool-proof groove is provided on the upper side of the inside of the mounting groove, a clamping position is provided on the top of the back side of the base, and buckles are installed on both sides of the pin on the back side of the base.

[0006] It is further defined that the foolproof groove includes a first step groove, a second step groove and a third step groove, the third step groove is arranged at the top of the installation groove, the second step groove is arranged at the top of the third step groove, and the first step groove is arranged at the top of the second step groove. Such a structural design prevents reverse insertion and affects the assembly of the socket.

[0007] It is further defined that the latching position is arranged in a U-shaped structure. Such a structural design facilitates subsequent assembly.

[0008] It is further defined that the base and the buckle are integrally formed. Such a structural design is convenient for production.

[0009] It is further defined that a positioning protrusion is further provided at the inner bottom of the installation groove, and the cross section of the positioning protrusion is arranged in a triangular structure. Such a structural design further improves the foolproof effect.

[0010] The beneficial effects of the utility model are as follows: the utility model has a simple structure, and through the three-stage step-type anti-fool and protective design structure and the tail plug-in card-type design, the socket fixation is enhanced when the upper plate is assembled, which can effectively prevent the socket from being plugged in reverse, and solves the problem of no positioning structure when the traditional socket is installed. It has the beneficial effects of being able to achieve anti-fool and structural stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0017] Embodiment 1, as Figure 1 and Figure 2 As shown, a fool-proof SN socket has a mounting groove 2 on the front of a base 1, pins 3 are installed on both sides of the inside of the mounting groove 2, the other side of the pin 3 penetrates the base 1 and extends to its outside, a fool-proof groove 4 is provided on the upper side of the inside of the mounting groove 2, a clamping position 5 is provided on the top of the back side of the base 1, and buckles 6 are installed on both sides of the pin 3 on the back side of the base 1.

[0018] In this embodiment, by setting the latch position 5, the fixation of the base 1 can be enhanced when the upper plate is assembled. By setting the mounting groove 2, the plug pin 3 can be protected. By setting the anti-mock groove 4, the insertion is smooth and reverse insertion is avoided. The base body will not be damaged when the product is forced to be plugged in and out, and smooth and convenient mutual insertion can be achieved. By setting the latch position 5, the base 1 can be fixedly installed, which saves costs and prevents the base 1 from falling off.
