DETAILED DESCRIPTION
[0036] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.
[0037] In order to solve the related technical problems existing in the prior art, the embodiment of the present application provides a space-type refrigerator ceiling light connector, which aims to solve the problems of the existing refrigerator ceiling light connector being difficult to plug in and out, and achieve the effect of stable connection of the connector. Figure 1 and 2 As shown, it specifically includes a main body 1 and an upper cover 4. The main body 1 has three PIN positions 2 distributed on the main body 1, and a connection terminal 3 is fixed in the PIN position 2. Figure 3 and 4As shown, PIN position 2 includes a first PIN position 201, a second PIN position 202, and a third PIN position 203. The first PIN position 201, the second PIN position 202, and the third PIN position 203 are arranged alternately. The first PIN position 201 is located on the first side of the main body 1, and the second PIN position 202 and the third PIN position 203 are located on the second side of the main body 1. The second PIN position 202 and the third PIN position 203 are arranged in a vertical direction and are staggered. The three PIN positions are integrated into one piece, enabling overall assembly and disassembly during installation, making assembly simple.
[0038] A wire hole 5 is formed on the side of the pin position for inserting wires. This hole is located on the main body 1. The wire ends of the terminal blocks 3 face and extend into this hole. The wires from the terminal blocks 3 are then led out of the connector through this hole. A wire return slot 6 is also included. It is located in the middle of the main body 1. One wire exits through the third pin position 203 through the hole 5 and bends through the slot. This ensures that all three wires exit in the same direction, ensuring easy assembly.
[0039] The upper cover 4 is provided on the upper end of the main body 1 and is used to press the terminal 3. Figure 9 As shown, the thrust stop 8 is formed at the top of the upper cover 4. During assembly, the thrust stop 8 is pressed into the wire threading hole 5 and restricts the connection terminal 3 from being pulled out.
[0040] like Figure 5 As shown, the connector further includes a resilient undercut 7 formed in the PIN slot and oriented obliquely toward the PIN slot insertion port, and the resilient undercut 7 abuts against the terminal 3. During installation, the terminal 3 is inserted through the PIN slot insertion port, and the resilient undercut 7 is squeezed and deformed by the terminal 3 until the terminal 3 is fully seated in the PIN slot. The resilient undercut 7 then rebounds to its original shape, abutting against the terminal 3, thereby securing the terminal 3 in the PIN slot and preventing it from falling out.
[0041] The upper cover 4 also includes a locking mechanism 9, which includes a lock catch 901 formed on the outer edge of the upper cover 4 and a clip 902 formed on the outer edge of the main body 1. The lock catch 901 cooperates with the clip 902. During installation, the upper cover 4 is placed against the main body 1, and the lock catch 901 on the outer edge of the upper cover 4 is fastened to the clip 902, thereby securing the upper cover 4 to the main body 1.
[0042] like Figure 7 As shown, the terminal 3 is a terminal with a U-shaped clip. During installation, the terminal on the base is inserted into the U-shaped clip of the terminal 3 and clamped by the U-shaped clip, thereby establishing a connection between the terminal 3 and the terminal on the base.
[0043] In order to ensure that the terminals in the PIN position fit tightly with the terminals on the base and prevent the connector from being separated from the base, a pushing and pressing device 10 is provided. Figure 6 and 8 As shown, the push-pressing device 10 is disposed within the main body 1 and includes a first push rod 1001, a second push rod 1002, and a push piece 1003. The first push rod 1001 and the second push rod 1002 are elastically hinged, with their elastic hinge point located above the return groove 6. One end of the first push rod 1001 is inserted into the first PIN position 201, and a push piece 1003 is vertically provided at one end of the second push rod 1002. The first end of the push piece 1003 extends into the second PIN position 202, and the second end of the push piece 1003 extends into the third PIN position 203. The first end of the push piece 1003 is hingedly disposed within the second PIN position 202.
[0044] The elastic hinge between the first push rod 1001 and the second push rod 1002 allows them to maintain a constant angle when not affected by external forces. When an external force acts on the hinge point between the first push rod 1001 and the second push rod 1002, the hinge point can be extended downward and outward, thereby aligning the first push rod 1001 and the second push rod 1002 on the same horizontal line. The push plate 1003, under the thrust of the second push rod 1002, rotates about its hinge point with the main body 1.
[0045] Press Figure 7 In the direction shown, insert each terminal 3 into the first PIN position 201, the second PIN position 202 and the third PIN position 203 respectively. Because the directions of each PIN position are different, the terminal 3 can be inserted into different PIN positions at one time, avoiding repeated operations.
[0046] Because the second PIN position 202 and the third PIN position 203 are not on the same vertical line, they are staggered, and the installation directions of the terminal 3 in the second PIN position 202 and the third PIN position 203 are also opposite, so both ends of the push piece 1003 can be inserted into the back of the terminal 3, and when the push piece 1003 rotates around its hinge point, it can squeeze the back of the terminal 3.
[0047] The pushing and pressing device 10 includes at least an initial state, and in the initial state, the first pushing rod 1001 and the second pushing rod 1002 are in a "∧" shape, such as Figure 6As shown, one end of the first push rod 1001 extends into the first PIN position 201 and abuts against the back of the terminal 3 in the first PIN position 201. The first end of the push piece 1003 extends into the second PIN position 202 and abuts against the back of the terminal 3 in the second PIN position 202. The second end of the push piece 1003 extends into the third PIN position 203 and abuts against the back of the terminal 3 in the third PIN position 203. Figure 6 As shown, when the wiring on the return trough 6 is not connected, the first push rod 1001 and the second push rod 1002 remain in the initial state, and the first push rod 1001 and the push piece have no pressurizing effect on the wiring terminal 3 in the PIN position.
[0048] The pushing and pressing device 10 also includes a use state, and in the use state, as shown in FIG. Figure 2 As shown, the hinge point between the first push rod 1001 and the second push rod 1002 is pushed downward, the first push rod 1001 pushes into the first PIN position 201, and the second push rod 1002 pushes the push piece 1003 to rotate around its hinge point, so that the first end of the push piece 1003 is close to the connection terminal 3 in the second PIN position 202, and the second end of the push piece 1003 is close to the connection terminal 3 in the third PIN position 203. Figure 2 As shown, when the wiring on the return groove 6 is connected, the first push rod 1001 and the second push rod 1002 are extended downward and outward by external force, and the first push rod 1001 squeezes the terminal 3 in the first PIN position 201. The push piece rotates around the hinge point with the main body 1 under the thrust of the second push rod 1002, so that the first end of the push piece 1003 squeezes the terminal 3 in the second PIN position 202, and the second end of the push piece 1003 squeezes the terminal 3 in the third PIN position 203, so that the terminal 3 in the PIN position tightly clamps the terminal on the foot to prevent the connector from detaching from the foot.
[0049] The present application improves the existing connector structure to make it miniaturized and integrated, and realizes the plug-in and pull-out functions of the connector in a limited space; at the same time, the three PIN positions are integrated into one body, and the overall assembly and disassembly are realized during installation; by setting the return groove 6, one of the wiring is reversed, so that the three output lines are in the same direction, ensuring the convenience of assembly; the PIN position in the present application is provided with a thrust structure, and the terminal needs to have a locking function to prevent the terminal from retreating to the PIN position. At the same time, there is a wire sequence guide to facilitate the assembly and manufacturing of the wiring harness.
[0050] During assembly, first open the top cover 4 and connect the wiring terminals 3. Once connected, insert the terminals 3 into the corresponding PIN positions according to the direction of the connection and snap them into place, providing a thrust-stopping effect. The wires exiting the PIN at the far end are passed through the return groove 6, ensuring the three wires are aligned and facilitating installation. Snap the top cover 4 onto the main body 1, completing the connector installation. Plug the corresponding PIN positions of the connector into the corresponding foot sockets to complete the electrical connection.
[0051] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
