[0024] In one embodiment of the present invention, Figure 1-3 As shown, a socket assembly for a socket is provided, including a socket body 100, the socket body 100 includes a first connecting portion 110; a first elastic sheet 120, a second elastic sheet 130 and a third elastic sheet 140 are arranged on the first connecting portion 110, the first elastic sheet 120 and the second elastic sheet 130 are arranged opposite to each other, the third elastic sheet 140 is arranged on one side of the first elastic sheet 120 and the second elastic sheet 130, the first elastic sheet 120, the second elastic sheet 130 and the third elastic sheet 140 jointly form a plug-in position, and an elastic limiting device 150 is arranged on the bottom of the first elastic sheet 120 and the second elastic sheet 130, and the elastic limiting device 150 is used to tightly connect the socket body 100 with the base;

[0025] The connector 200, the socket body 100 is detachably connected to the connector 200, and the connector 200 includes a second connecting portion 210; a fixing portion 220 is provided at one end of the second connecting portion 210, and a wiring portion 230 is provided at the other end, and the fixing portion 220 is provided with a fixing hole 221, and the fixing hole 221 is used to install the socket body 100, and a wiring hole 231 is also provided on the wiring portion 230, and the wiring hole 231 is used to install the wiring terminal.

[0026] Specifically, the plug on the plug is inserted into the plug-in position to achieve a conductive connection. Furthermore, the socket body 100 is detachably connected to the connector 200. When the socket body 100 fails, we only need to disassemble the socket and replace the socket in the socket without replacing the entire socket assembly. This saves costs and is convenient for replacing different socket bodies 100 to meet the different needs of users. The elastic limit device 150 provided at the bottom of the first spring piece 120 and the second spring piece 130 can make the socket and the base more tightly connected, and is not easy to fall off during long-term use, thereby improving the stability and safety of the socket and preventing short circuits.

[0027] In another embodiment of the present invention, Figure 2 and 3 As shown, the first spring piece 120 and the second spring piece 130 have the same structure. The first spring piece 120 includes a first clamping portion 121 and a first contact arc portion 122 connected to the first clamping portion 121; the second spring piece 130 includes a second clamping portion 131 and a second contact arc portion 132 connected to the second clamping portion 131; the first connecting portion 110 is connected to the first clamping portion 121 and the second clamping portion 131 at both ends; the first clamping portion 121 and the second clamping portion 131 form a plug-in channel 160, and the first contact arc portion 122 and the second contact arc portion 132 form an elastic plug-in gap 170. The first contact arc portion 122 and the second contact arc portion 132 are respectively provided with a first guide portion 123 and a second guide portion 133 at one end, and the first guide portion 123 and the second guide portion 133 extend upward and away from each other.

[0028] Specifically, the plug on the plug is inserted into the plug channel 160 through the plug-in gap 170 to be electrically connected to the socket, and the first clamping portion 121 and the second clamping portion 131 have an inward force, so that the first contact arc portion 122 and the second contact arc portion 132 clamp the plug to form an electrical connection. The first guide portion 123 and the second guide portion 133 are used to guide the insertion of the plug on the plug.

[0029] In another embodiment of the present invention, Figure 2 and 3As shown, the elastic limiting device 150 includes an elastic limiting block 151; the bottom of the first elastic sheet 120 and the second elastic sheet 130 are each provided with a through square opening 152, and each square opening 152 is provided with an elastic limiting block 151 obliquely, and when the socket body 100 is plugged into the base, the elastic limiting block 151 can abut against the inner wall of the base to prevent the socket body 100 from falling off from the base. The elastic limiting device 150 also includes two limiting protrusions 153, and the two limiting protrusions 153 are symmetrically arranged around the elastic limiting block 151.

[0030] Specifically, when the socket body 100 and the base are sleeved together from small to top, the elastic limit block 151 returns to the square opening 152 from the inclined state due to the pressure of the inner wall of the base. The elastic limit block 151 has the force to restore the elastic deformation, so that the elastic limit block 151 presses against the inner wall of the base, making the connection tighter and not easy to fall off during long-term use. Similarly, the same is true for the limiting protrusion 153. When the socket body 100 and the base are sleeved together from small to top, the limiting protrusion 153 is compressed. The limiting protrusion 153 has the force to restore the elastic deformation and presses against the inner wall of the base, making it tightly combined, thereby improving the stability and safety of the socket and not easy to fall off.

[0031] In another embodiment of the present invention, Figure 1 As shown, a through hole 111 is provided on the first connection part 110, and the through hole 111 is coaxial with the fixing hole 221. The rivet 300 passes through the through hole 111 and the fixing hole 221 in sequence so that the socket body is installed on the fixing part 220. Specifically, the socket body is detachably connected to the connecting member 200 through the rivet 300. When the socket body 100 fails, we only need to disassemble the socket and replace the socket in the socket without replacing the entire socket assembly, which saves costs and is also convenient for replacing different socket bodies 100 to meet different needs of users.

[0032] In another embodiment of the present invention, Figure 1 As shown, the fixing portion 220, the second connecting portion 210 and the wiring portion 230 are integrally stamped and formed. Integral stamping does not require any welding, which reduces the manufacturing cost and the use of materials while achieving good large-area contact performance and reliability, and at the same time reduces the problems of fracture, short circuit, looseness or non-vibration resistance caused by welding, and indirectly improves production efficiency and the stability of the overall structure of the connector 200.

[0033] In another embodiment of the present invention, Figure 1 As shown, the wiring portion 230 is also provided with a positioning hole 232, which is used for positioning and installation, and the rivet 300 passes through the positioning hole 232 to install the plug sleeve assembly on the base. The positioning hole 232 can be used for rapid assembly, thereby improving production efficiency.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
