Description

Technical Field

[0001] This utility model relates to the technical field of sockets, and more specifically to a quick-connect power cord and socket for a socket. Background Technology

[0002] In the existing technology, the connection between the external power cord of the socket and the corresponding connecting copper strip inside the socket requires manual operation. This is because the connecting section of the power cord is a flexible wire, and the machine cannot accurately position and grasp it during the process of wire management and welding with the connecting copper strip, so automated connection and assembly cannot be achieved. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a quick-connect power cord for a socket, wherein the connecting section of the power cord is set as a rigid pin, which facilitates quick positioning by the machine and makes it easier for the machine to weld it to the connecting copper strip, thereby realizing automated connection and assembly.

[0004] The technical solution of this utility model is to provide a quick-connect power cord for a socket, including at least two cables. Each power cord has a connecting end, and all cables extend into the connecting end and are electrically connected to a rigid pin. A pin bracket is provided inside the connecting end to fix each pin. An insulating outer layer is provided on the outer surface of the connecting end; this insulating outer layer is an insulating layer used to wrap the cables inside the connecting end, the portions of each pin connected to the cables, and the pin bracket. Each pin extends out of the insulating outer layer for external electrical connection.

[0005] Compared with the prior art, the quick-connect power cord of the socket of this utility model has the following advantages: In the connection end, each pin is electrically connected to the corresponding cable and fixed by a pin bracket. Except for the part of each pin that extends out of the insulating outer coating, the other parts, including the cable, are wrapped with insulating outer coating to insulate against the outside and ensure safe use. Each pin is rigid and fixed, so there is no need to manage the cable. There is no need to set up a winding post for managing the power cord in the socket. The machine can quickly position each pin and weld it to the connecting copper strip in the socket, so that the connection and assembly between the power cord and the connecting copper strip of the socket is automated, the level of process automation is improved, and the probability of poor soldering and missing soldering caused by human factors on the production line is reduced.

[0006] Preferably, there are three cables, each electrically connected to one of the three pins: an L (low) pin, a N (north) pin, and an E (export) pin. These three pins extend from the insulating outer sheath in three different directions. This structure, with the three pins extending from the insulating outer sheath separately in three different directions, prevents short circuits between them during soldering with the connecting copper strip in the socket.

[0007] Preferably, the L-pin, N-pin, and E-pin are spatially perpendicular to the three sides of a cube, with the sides of the cube containing the three pins connected sequentially, and the sides of the cube containing two of the pins being parallel to each other. This structure makes it easier to determine the coordinates of the three pins, facilitating rapid machine positioning and docking with the corresponding connecting copper strips.

[0008] Preferably, the side of the cube containing the L-pin is parallel to the side of the cube containing the N-pin, and the side of the cube containing the E-pin is located between the side of the cube containing the L-pin and the side of the cube containing the N-pin. This structure keeps the L-pin and N-pin far apart and opposite in direction, preventing short circuits during soldering with the connecting copper strip in the socket.

[0009] Preferably, the pin includes a cable connection end, which is riveted to a corresponding cable to achieve electrical connection. This structure ensures a secure connection and good electrical contact between the pin and the corresponding cable.

[0010] Preferably, the pin holder has adhesive wrapping around the middle of each pin to secure it. This structure allows the pin holder to hold the pin in place, preventing movement during soldering of the pin to the connecting copper strip in the socket and thus avoiding any impact on the soldering quality.

[0011] Preferably, the pin includes a soldering end that extends beyond the insulating outer coating and has a flat structure for external soldering. This flat structure facilitates external soldering.

[0012] Preferably, the welding end is provided with a welding boss for external resistance welding connection. This structure, with the welding boss, facilitates resistance welding connection with the connecting copper strip in the socket, significantly reducing welding costs compared to soldering, and increasing the application rate of resistance welding structures.

[0013] This utility model provides a socket. The technical solution includes a socket housing, with at least one base and at least two connecting copper strips inside the socket housing. The base contains an L-pole sleeve and an N-pole sleeve, and the socket housing contains L-pole connecting copper strips that are electrically connected to the L-pole sleeves and N-pole sleeves in all the bases, respectively. Alternatively, the base contains an L-pole sleeve, an N-pole sleeve, and an E-pole sleeve, and the socket housing contains L-pole connecting copper strips that are electrically connected to the L-pole sleeves, N-pole sleeves, and E-pole sleeves in all the bases, respectively. A quick-connect power cord for the socket is connected to the socket housing as described above. The connecting end is inserted into the socket housing, and the protruding, insulated, rubber-coated pins are welded one-to-one with the connecting copper strips of the same polarity.

[0014] Compared with the prior art, the socket of this utility model has the following advantages: all the pins of the power cord connection end are rigid and fixed, so there is no need to manage the cord. There is no need to set up winding posts for managing the power cord inside the socket. The layout is simple. Each pin can be quickly positioned by machine and welded to the corresponding connecting copper strip in the socket, so that the connection and assembly between the power cord and the connecting copper strip of the socket is automated.

[0015] Preferably, the plane for welding the pin corresponds to the plane for welding on the connecting copper strip of the same polarity, and both are perpendicular to the plane of the socket extending outward on the base. This structure facilitates resistance welding between the socket and the connecting copper strip of the same polarity, as well as between the pin and the connecting copper strip of the same polarity. This increases the application rate of resistance welding, reduces costs, and lowers the risk of incomplete or missed solder joints. Attached Figure Description

[0024] like Figure 3 As shown, the quick-connect power cord 1 of the socket of this utility model is provided with three cables 3. The power cord is provided with a connecting end. Each cable 3 extends into the connecting end and is electrically connected to a rigid pin. The three pins are the L-pin 6, N-pin 7, and E-pin 8. One end of each pin is provided as a cable connecting end 9, which is riveted to the corresponding cable 3 to achieve electrical connection. The other end of each pin is provided as a soldering end 10. The soldering end 10 has a flat structure and is provided with a soldering boss 11. The three pins point in three different directions. The L-pin 6 and N-pin 7 are both bent in the middle. Their soldering ends 10 are in opposite directions and are located on the same straight line. The E-pin 8 is located between the L-pin 6 and N-pin 7.

[0025] like Figure 2 As shown, a pin bracket 5 is provided inside the connection end. The pin bracket 5 is coated with glue in the middle of each pin to fix each pin. The pin bracket 5 has a cuboid structure. The L-pin 6, N-pin 7 and E-pin 8 are perpendicular to the three sequentially connected left side, front side and right side of the pin bracket 5. The left side and right side of the pin bracket 5 where the L-pin 6 and N-pin 7 are located are parallel to each other. The front side of the pin bracket 5 where the E-pin 8 is located is located between the left side and right side of the pin bracket 5 where the L-pin 6 and N-pin 7 are located.

[0026] like Figure 1 As shown, the outer layer of the connector is provided with an insulating outer coating 4, which is an insulating layer used to wrap the connector, including the cable 3 inside the connector, the cable connection ends 9 of each pin, the middle part, and the pin support 5; the soldering ends 10 of each pin extend out of the insulating outer coating 4 for external soldering. A tail clip 2 is provided on the power cord adjacent to the connector.

[0027] The socket of this utility model uses the aforementioned quick-connect power cord 1 to connect to the external power source, such as... Figure 4As shown, the connecting end is inserted into the socket housing 12, and the socket housing 12 cooperates with the tail clip 2 to limit the connection end; at least one base 13 is provided inside the socket housing 12, and an L-pole sleeve, an N-pole sleeve, and an E-pole sleeve are provided inside the base 13.
