Description

Technical Field

[0001] The utility model relates to the field of electrical components, in particular to an improved socket terminal. Background Art

[0002] Socket terminals are components on the socket used to connect power cords or electrical devices. They are usually located inside the socket or on the outer shell. They are responsible for transmitting current from the power cord to the electrical devices in the socket and are one of the key components of circuit connection. The design and installation of socket terminals must comply with relevant safety standards and regulations to ensure the stability, reliability and safety of circuit connections. In addition, when installing and using socket terminals, special attention should be paid to insulation, contact, waterproof and dustproof issues to avoid circuit failure or electric shock hazards.

[0003] In the prior art, a socket is often used in conjunction with a plug. However, during daily use, the plug and the socket may become loose after being subjected to external vibration or impact, resulting in an unstable connection between the two. This is especially likely to occur on mobile devices or mobile sockets. Therefore, an improved socket terminal is proposed to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides an improved socket terminal, which has the advantages of stable connection and solves the problem of instability between the plug and the socket.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an improved socket terminal, comprising a body and a shell, the body being inserted into the shell, a connecting portion being formed at the middle portion of the body, the connecting portion being inserted into the shell and abutting against the inner side wall of the shell, the cross-sectional shape of the connecting portion being circular, at least one groove being provided at a portion of the outer periphery of the connecting portion located inside the shell, an elastic plate being provided in the groove, a positioning block being fixed on a side of the elastic plate away from the connecting portion and away from the portion where the elastic plate is connected to the groove, the vertical projection of the positioning block falling on the inner bottom wall of the groove, a first inclined surface being provided on a side of the positioning block close to the inner side wall of the shell, a positioning groove being provided on the inner peripheral wall of the shell corresponding to the positioning block, and the positioning block being slidably inserted in the positioning groove.

[0006] Furthermore, the groove is opened on the outer periphery of the connecting portion along the transverse direction, and the inner bottom wall of the groove is inclined inwardly, and the elastic plate is fixed to a portion of the inner bottom wall of the groove close to the outer periphery of the connecting portion.

[0007] Furthermore, a rotating sleeve is rotatably connected to the outer periphery of the connecting part, the outer periphery of the rotating sleeve abuts against the inner wall of the outer shell, a through-hole is provided on the rotating sleeve corresponding to the positioning block, the side of the elastic plate away from the connecting part abuts against the inner wall of the rotating sleeve, the positioning block is slidably inserted into the through-hole, and is connected to the positioning groove through the through-hole, and a second inclined surface is provided on the front and rear sides of the positioning block.

[0008] Furthermore, a moving space is formed between the through hole and the first inclined surface for the positioning block to move, and a gap is formed between the vertical projection of the positioning block and the left wall inside the groove, and the gap is equal to the width of the moving space.

[0009] Furthermore, a through hole is provided on the main body at a position away from the connecting portion, and a nut is fixed in the corresponding through hole on the main body.

[0010] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0011] The improved socket terminal, through the positioning block and the positioning groove, can restrict the body after the body is assembled in the shell. Under the action of the positioning block, the body cannot move in the shell, thereby improving the stability of the assembly and preventing the body from loosening due to external influences. At the same time, under the action of the rotating sleeve and the perforation, the positioning block can also be quickly separated from the positioning groove, making it more convenient to separate the body from the shell when it needs to be separated.

[0015] In the figure: 1 connecting portion, 2 housing, 3 body, 4 through hole, 5 nut, 6 sleeve, 7 groove, 8 elastic plate, 9 positioning block, 10 through hole, 11 first inclined surface, 12 positioning groove, 13 second inclined surface. DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example 1:

[0018] See also Figure 1-2 , an improved socket terminal in this embodiment includes a body 3 and a shell 2, the body 3 is inserted into the shell 2, and a connecting portion 1 is formed at the middle part of the body 3, the connecting portion 1 is inserted into the shell 2 and abuts against the inner side wall of the shell 2, the cross-sectional shape of the connecting portion 1 is circular, and at least one groove 7 is opened on the outer periphery of the connecting portion 1 at a position located inside the shell, an elastic plate 8 is arranged in the groove 7, a positioning block 9 is fixed on the side of the elastic plate 8 away from the connecting portion 1 and away from the connection between it and the groove 7, the vertical projection of the positioning block 9 falls on the inner bottom wall of the groove 7, the positioning block 9 is provided with a first inclined surface 11 on a side close to the inner side wall of the shell 2, and a positioning groove 12 is opened on the inner peripheral wall of the shell 2 corresponding to the positioning block 9, and the positioning block 9 is slidably inserted in the positioning groove 12.

[0019] When in use, when connecting the main body 3 with the shell 2, the connecting part 1 needs to be inserted into the shell 2. After the connecting part 1 moves into the shell 2 and contacts the positioning block 9, under the action of the continuously moving connecting part 1, the end face of the shell 2 cooperates with the first inclined surface 11 to squeeze the positioning block 9, so that the positioning block 9 moves into the groove 7. After the positioning block 9 moves into the groove 7, the shell 2 squeezes the elastic plate 8 through the positioning block 9 to deform it, and during the movement of the connecting part 1, it will also squeeze the positioning block 9 through its inner circumferential wall. After the connecting part 1 drives the positioning block 9 to move to the positioning groove 12 and aligns with it, the extrusion force on the positioning block 9 disappears, and the elastic sheet is also reset under the action of its elastic force, so that the positioning block 9 is inserted into the positioning groove 12. With the cooperation of the positioning block 9 groove, the main body 3 and the shell 2 can be locked, making the connection between the two more stable to avoid loosening.

[0020] Example 2:

[0021] The basic content is the same as Example 1, except that:

[0022] See also Figure 1-2 In this embodiment, the groove 7 is opened on the outer periphery of the connecting portion 1 along the transverse direction, and the inner bottom wall of the groove 7 is inclined inward, and the elastic plate 8 is fixed on the inner bottom wall of the groove 7 near the outer periphery of the connecting portion 1.

[0023] During application, during the movement of the connecting part 1, the squeezed positioning block 9 will exert an extrusion force on the elastic plate 8. At this time, the elastic plate 8 will fit with the inner bottom wall of the groove 7 after deformation, and the positioning block 9 is also located in the groove 7 to prevent obstruction of the movement of the connecting block.

[0024] In another specific embodiment, the groove 7 is opened on the outer circumference of the connecting portion 1 along the circumferential direction.

[0025] Example 2:

[0026] The basic content is the same as Example 1, except that:

[0027] See also Figure 2-3 In this embodiment, a rotating sleeve 6 is rotatably connected to the outer periphery of the connecting part 1, and the outer periphery of the rotating sleeve 6 abuts against the inner peripheral wall of the outer shell 2. A through-hole 10 is opened on the rotating sleeve 6 corresponding to the positioning block 9. The side of the elastic plate 8 away from the connecting part 1 abuts against the inner peripheral wall of the rotating sleeve 6. The positioning block 9 is slidably inserted into the through-hole 10 and is connected to the positioning groove 12 through the through-hole 10. A second inclined surface 13 is provided on the front and rear sides of the positioning block 9.

[0028] A moving space is formed between the through hole 10 and the first inclined surface 11 for the positioning block 9 to move. A gap is formed between the vertical projection of the positioning block 9 and the left wall of the groove 7, and the gap is equal to the width of the moving space.

[0029] During use, by rotating the rotating sleeve 6, the positioning block 9 will be squeezed under the cooperation of the perforation 10 on the rotating sleeve 6 and the second inclined surface 13, so that it is moved out of the positioning groove 12 until it moves into the groove 7. When the positioning block 9 is separated from the positioning groove 12, the lock between the connecting part 1 and the shell 2 can be released, which facilitates separation.

[0030] Example 3:

[0031] The basic content is the same as Example 1, except that:

[0032] See also Figure 1 In this embodiment, a through hole 4 is provided on the top surface of the main body 3 away from the main body 3, and a nut 5 is connected to the through hole 4.

[0033] When in use, a bolt is connected to the nut 5 and a connecting wire is placed between the two. The connecting guide can be connected to the body 3 under the cooperation of the two.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
