Description

Technical Field

[0001] This utility model belongs to the field of electrical technology, and specifically refers to the structure of a power socket. Background Technology

[0002] Plugs and sockets are common electrical accessories used in daily life to connect power sources to electrical devices. However, traditional power sockets have some structural defects, such as inconvenience in plugging and unplugging, easy loosening, and insufficient safety protection. For example, sockets adapted to plugs with cylindrical connecting terminals lack sufficient restraint, causing the plug to become loose after a certain number of plugging and unplugging cycles, and it may fall off the socket with slight force. At the same time, this type of socket usually requires two components to achieve the grounding and shielding functions of the product, which complicates the assembly process. Utility Model Content

[0003] The main purpose of this utility model is to provide a power socket structure that solves the problems existing in the prior art, can stabilize the cooperation between the plug and the socket, and has a simple production process and low cost.

[0004] To achieve the above objectives, the solution of this utility model is:

[0005] A power socket structure includes a connecting terminal, a spring, cables, a socket body, and a guide; the spring and the connecting terminal are arranged parallel to each other, and their ends in the same direction are respectively connected to two cables; the socket body is formed by an injection molding process and encapsulates the connecting terminal and the spring, and is provided with a socket hole coaxial with the connecting terminal and a movable groove communicating with the socket hole; the socket hole extends to the end face of the socket body; the spring has an elastic part that fits in the movable groove; the guide is provided on the end face of the socket body and is provided with a through hole coaxial with the socket hole, and the inner wall of the through hole is provided with several protrusions.

[0006] The connecting terminal and the spring are respectively provided with a first ring and a second ring at their oriented ends. After the end of the cable is inserted into the first ring and the second ring, it is connected and fixed by crimping or welding.

[0007] The connecting terminal and the spring are respectively provided with a first protrusion and a second protrusion at the middle section. The first protrusion and the second protrusion are embedded into the socket body after the socket body is formed.

[0008] The movable slot extends through the side of the socket body.

[0009] The socket body has several locking blocks on its circumference, and the guide member has a connecting piece bent into shape on its side. The connecting piece engages with the locking blocks at the corresponding positions.

[0010] Preferably, the connecting piece is provided with a snap-fit ​​hole that matches the card block.

[0011] The protrusions are arranged at equal angular intervals around the axis of the perforation.

[0012] The protruding corners are rounded.

[0013] After adopting the above technical solution, the present invention has the following technical effects:

[0014] This invention utilizes an injection molding process to quickly mold the socket body, encapsulating the connecting terminals and spring contacts, thus saving processing steps and time. Furthermore, the socket body formed using this injection molding process exhibits high stability and can withstand humid and dusty environments. This invention employs a guide component made of a material that simultaneously possesses conductive and shielding functions, which is then installed on the end face of the socket body. The protrusion within its perforation secures the cylindrical terminals of the plug, preventing plug movement. Moreover, because the guide component itself is conductive, it also provides grounding upon contact with the cylindrical terminals. Simultaneously, the elastic portion applies pressure to the cylindrical terminals, ensuring a tight bond between them. Attached Figure Description

[0024] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0025] refer to Figure 1-3 As shown, this utility model discloses a power socket structure, including a connecting terminal 1, a spring contact 2, a cable 3, a socket body 4, and a guide member 5;

[0026] The spring 2 and the connecting terminal 1 are arranged parallel to each other, and their ends in the same direction are respectively connected to two cables 3;

[0027] The socket body 4 is formed by insert molding and wraps the connecting terminal 1 and the spring piece 2. It is provided with a socket hole 41 coaxial with the connecting terminal 1 and a movable groove 42 communicating with the socket hole 41. The socket hole 41 extends to the end face of the socket body 4. The spring piece 2 has an elastic part 21 that fits in the movable groove 42.

[0028] The guide member 5 is provided on the end face of the socket body 4 and has a through hole 51 coaxial with the socket 41. The inner wall of the through hole 51 has several protrusions 52.

[0029] Through the above-mentioned solution, this utility model can quickly mold the socket body 4 to encapsulate the connecting terminal 1 and the spring 2 using the embedded injection molding process, thereby saving processing steps and time. Furthermore, the socket body 4 molded by the embedded injection molding process has high stability and can resist humid and dusty environments. This utility model can use a material with both conductive and shielding functions to make a guide 5, which is installed on the end face of the socket body 4. The protrusion 52 in its through hole 51 fixes the cylindrical terminal of the plug, preventing the plug from shaking. Since the guide 5 itself is conductive, it can also achieve grounding after contacting the cylindrical terminal. At the same time, the elastic part 21 can also apply pressure to the cylindrical terminal to make it tightly bonded to the connecting terminal 1.

[0030] The following are specific embodiments of the present invention.

[0031] The connecting terminal 1 and the spring 2 are respectively provided with a first ring 11 and a second ring 22 at their oriented ends. After the end of the cable 3 is inserted into the first ring 11 / second ring 22, it is connected and fixed by crimping or welding, which has high structural stability.

[0032] The middle sections of the aforementioned connecting terminal 1 and spring 2 are respectively provided with a first protrusion 12 and a second protrusion 23. After the socket body 4 is formed, the first protrusion 12 and the second protrusion 23 are embedded in the socket body 4 so that they are more firmly combined with the socket body 4 after injection molding and are not easy to shake.

[0033] The aforementioned connecting terminal 1 is made of brass, preferably copper plated with nickel.

[0034] The aforementioned movable groove 42 penetrates the side of the socket body 4, facilitating demolding.

[0035] The socket body 4 is provided with several locking blocks 43 on its periphery. The guide 5 is bent into a connecting piece 53 on its side. The connecting piece 53 engages with the locking block 43 at the corresponding position to achieve the installation and fixation of the guide 5 on the socket body 4.

[0036] Furthermore, the connecting piece 53 is provided with a snap-fit ​​hole 54 that matches the snap-fit ​​block 43.

[0037] The protrusions 52 are arranged at equal angular intervals around the axis of the perforation 51 to achieve a uniform distribution of the protrusions 52.

[0038] The corners of the aforementioned protrusion 52 can be rounded to reduce wear on the plug.

[0039] The production process of this utility model is as follows: (1) Press / weld the two cables 3 to the connecting terminal 1 and the spring 2 respectively; (2) Use a specific mold to embed and inject the socket body 4 and wrap the connecting terminal 1 and the spring 2; (3) Demold and take out the semi-finished product, and then install the guide 5 on the end face of the socket body 4.

[0040] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
