Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, in particular to a T-shaped connector base which is easy to assemble and disassemble. Background Art

[0002] A connector is a common wire connector that is widely used in low-voltage circuits. Its basic structure consists of two parts: a pin and a socket. According to the requirements of the circuit, the pins will be evenly distributed in the base of the plug, and the sockets will be evenly distributed in the docking base. The socket is usually provided with an opening for receiving the pins and fastening them. The pins and sockets are usually made of metal materials, and the two are electrically connected by insertion. After the pin is inserted into the socket, the metal contact surfaces of the two fit tightly to form a conductive path, thereby realizing the transmission of current or signal. There are many types of connectors, among which the T-type connector is a connector used to branch out one or more branches from the main line. Its shape is similar to the letter "T". It is usually used in electrical, communication or data transmission systems to realize the distribution of signals or currents. It usually has one input port and two output ports to facilitate signal distribution or line expansion. Each port uses a plug and socket to connect the lines.

[0003] In the prior art, during the assembly and disassembly of the plug and socket, the threaded sleeve on the outside of the base is used to lock the threads after the plug is fully connected. Although this assembly and disassembly method is relatively convenient, when the connector is placed on the ground using an electric wire connection, the threaded sleeve is easily rotated when the connector is dragged on the ground, resulting in locking failure. Based on the above situation, after the pin is inserted into the socket, the metal contact surfaces of the two are tightly fitted, which is prone to wear after repeated insertion and removal, and the pin is more likely to fall out of the socket.

[0004] In response to the above problems, it is urgent to carry out innovative design based on the original connector. Summary of the Invention

[0005] The technical solution of the present invention addresses the technical problem that the existing technical solutions are too simple, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a T-shaped connector base that is easy to disassemble and assemble, so as to solve the problem proposed in the above background technology that when the connector is placed on the ground using wires for connection, the threaded sleeve is easily rotated when the connector is dragged on the ground, resulting in locking failure. Based on the above situation, after the pin is inserted into the socket, the metal contact surfaces of the two are tightly fitted, which is prone to wear after repeated plugging and unplugging, and the pin is more likely to fall out of the socket.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a T-shaped connector base that is easy to assemble and disassemble, comprising a connector body, a connector pin base, a pin, a connector socket, a socket, and a pin slot, and further comprising a locking assembly disposed on the outer walls of the connector pin base and the connector socket for initial fixation during insertion, a conducting assembly disposed on the pin and the socket for wear-free contact and secondary fixation during insertion and conduction, and a limiting assembly disposed on the connector pin base and the connector socket for precise alignment during insertion;

[0007] The conducting assembly includes an elastic metal piece arranged at one end of the pin for cooperating with the pin slot and deforming according to the plugging and unplugging state.

[0008] Preferably, the pins are evenly distributed inside the connector pin seat, and the sockets are evenly distributed inside the connector hole seat, and the pins and the sockets are arranged correspondingly.

[0009] Preferably, the locking assembly includes a threaded sleeve fixed on the outer wall of the connector needle seat, the outer wall of the connector hole seat is provided with a nut that slides with it, the outer wall of the threaded sleeve is threadedly engaged with the inner wall of the nut, and the outer wall of the connector hole seat is located on one side of the nut to fix a limiting ring.

[0010] Preferably, the conductive component also includes an inner cavity opened inside the pin, and a movable block that slides with the inner cavity is provided inside the inner cavity. The movable block is connected to a center column that rotates toward the outer wall of the socket, and the outer wall of the center column is provided with a guide structure.

[0011] Preferably, the elastic metal piece is configured as a spiral structure, and one end of the elastic metal piece is fixed to the end of the center column, and one end of the elastic metal piece is fixed to the end of the pin.

[0012] Preferably, the diameter of the elastic metal piece gradually increases from both ends to the middle, and the needle groove is located on one side of the outer wall of the elastic metal piece and is configured as a conical structure.

[0013] Preferably, the conductive component also includes a first connecting rod fixed between a moving block inside the middle pin and a moving block inside the outer pin, the outer wall of the threaded sleeve is provided with a moving ring that slides with it, and a second connecting rod is respectively connected between the moving block of the outer pin and the moving ring.

[0014] Preferably, the connector needle seat, the threaded sleeve and the pin are all provided with sliding grooves that slidably cooperate with the first connecting rod and the second connecting rod.

[0015] Preferably, the guide structure includes a guide column fixed to the inner wall of the inner cavity, and the outer wall of the central column is provided with a guide groove that slides with the guide column, and the guide groove is a spiral structure.

[0016] Preferably, a card block is provided on the inner wall of the plug-in end of the connector needle seat, and a card groove corresponding to the card block is provided on the outer wall of the connector hole seat.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention provides an elastic metal piece with a spiral structure. When plugging in, the center column rotates while moving, and the end of the center column pulls the elastic metal piece to deform, and while stretching the elastic metal piece, it drives one end of the elastic metal piece to rotate. Since the elastic metal piece has a spiral structure, and one end of the elastic metal piece is fixed to the end of the center column and the other end is fixed to the end face of the pin, the elastic metal piece contracts during the stretching and rotation process. At this time, the spiral diameter in the middle of the elastic metal piece is large enough to pass through the notch of the needle groove. When the connector is placed on the ground with an electric wire connection, the nut is easily rotated when the connector is dragged on the ground for a long time. Even if the nut comes off the threaded sleeve, the spiral diameter in the middle of the elastic metal piece is larger than the notch of the needle groove, and the pin cannot be separated from the socket, thereby further improving the plugging stability of the connector when in use.

[0019] Secondly, when the elastic metal part is inserted into the needle groove, the structural characteristics of the elastic metal part itself are utilized to reduce the wear caused by hard friction during insertion, thereby increasing the service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0033] See also Figures 1 to 11 The present invention provides a technical solution: a T-shaped connector base that is easy to assemble and disassemble, comprising a connector body 1, a connector needle seat 2, a pin 4, a connector hole seat 14, a socket 15, and a needle groove 16, and further comprising a locking assembly provided on the outer walls of the connector needle seat 2 and the connector hole seat 14 for preliminary fixation during insertion, a conducting assembly provided on the pin 4 and the socket 15 for wear-free contact and secondary fixation during insertion and conduction, and a limiting assembly provided on the connector needle seat 2 and the connector hole seat 14 for precise alignment during insertion;

[0034] The conducting assembly includes an elastic metal member 8 provided at one end of the plug pin 4 for cooperating with the pin slot 16 and deforming according to the plugging and unplugging state.

[0035] The pins 4 are evenly distributed inside the connector needle seat 2, and the sockets 15 are evenly distributed inside the connector hole seat 14, and the pins 4 and the sockets 15 are correspondingly arranged.

[0036] It should be noted that the connector body 1, the connector needle seat 2 and the connector hole seat 14 are all made of non-conductive materials, and the pins 4, the elastic metal part 8 and the socket 15 are all made of conductive materials. The connector body 1 is the same as the body of the T-type connector in the prior art, and the number and position of the pins 4 and the socket 15 correspond to each other.

[0037] The locking assembly includes a threaded sleeve 3 fixed on the outer wall of the connector needle seat 2, and the outer wall of the connector hole seat 14 is provided with a nut 17 that slides with it. The outer wall of the threaded sleeve 3 is threadedly engaged with the inner wall of the nut 17, and the outer wall of the connector hole seat 14 is located on one side of the nut 17 to fix a limiting ring 18.

[0038] It should be noted that the initial fixation of the connector needle seat 2 and the connector hole seat 14 during plugging can be completed by rotating the nut 17 , and the limiting ring 18 limits the moving nut 17 .

[0039] The conducting component also includes an inner cavity 5 opened inside the pin 4, and a movable block 6 is provided inside the inner cavity 5 to slide with it. The movable block 6 is connected to the center column 7 when rotated toward the outer wall of the socket 15, and the outer wall of the center column 7 is provided with a guide structure.

[0040] It should be noted that the central column 7 is located at the center of the outer wall of the moving block 6, and the central column 7 can be rotated during movement by utilizing the guide structure.

[0041] The elastic metal piece 8 is configured as a spiral structure, and one end of the elastic metal piece 8 is fixed to the end of the center column 7 , and one end of the elastic metal piece 8 is fixed to the end of the pin 4 .

[0042] It should be noted that one end of the elastic metal member 8 is fixed, and the other end is pulled and rotated, so that the elastic metal member 8 contracts during the process of stretching and rotating.

[0043] The diameter of the elastic metal member 8 gradually increases from both ends to the middle, and the needle groove 16 is located on one side of the outer wall of the elastic metal member 8 and is configured as a conical structure.

[0044] It should be noted that, in the initial state of the elastic metal member 8 , the outer wall of the elastic metal member 8 is tightly fitted to the inner wall of the needle groove 16 , and the spiral diameter in the middle of the elastic metal member 8 is larger than the notch of the needle groove 16 .

[0045] The conducting assembly also includes a first connecting rod 9 fixed between the moving block 6 inside the middle pin 4 and the moving block 6 inside the outer pin 4. The outer wall of the threaded sleeve 3 is provided with a moving ring 12 that slides with it, and a second connecting rod 13 is respectively connected between the moving block 6 of the outer pin 4 and the moving ring 12.

[0046] The connector needle seat 2 , the threaded sleeve 3 and the pin 4 are all provided with sliding grooves that slidably cooperate with the first connecting rod 9 and the second connecting rod 13 .

[0047] It should be noted that the distances of the slide grooves are the same, and the first connecting rod 9 and the second connecting rod 13 are both made of non-conductive materials. After pushing the movable ring 12, the first connecting rod 9 and the second connecting rod 13 can slide in the corresponding slide grooves, so that the movable blocks 6 move synchronously in the inner cavity 5 of the pin 4.

[0048] The guide structure includes a guide column 10 fixed to the inner wall of the inner cavity 5. The outer wall of the central column 7 is provided with a guide groove 11 that is slidably matched with the guide column 10. The guide groove 11 is a spiral structure.

[0049] It should be noted that the guide post 10 on the inner wall of the inner cavity 5 slides in the guide groove 11 on the outer wall of the central post 7, so that the central post 7 rotates while moving.

[0050] A clamping block 19 is provided on the inner wall of the plug-in end of the connector needle seat 2 , and a clamping groove 20 corresponding to the clamping block 19 is provided on the outer wall of the connector hole seat 14 .

[0051] It should be noted that, when plugging in, the card block 19 corresponds to the card slot 20 , so that the pin 4 and the socket 15 are docked in an orderly manner, ensuring the accuracy of the plugging in.

[0052] Working principle: First, the connector body 1 needs to plug and install each end during the disassembly and assembly process. First, push the moving ring 12 to slide on the outer wall of the threaded sleeve 3, and slide the first connecting rod 9 and the second connecting rod 13 in the corresponding slide groove, so that the moving block 6 moves synchronously in the inner cavity 5 of the pin 4, and the moving block 6 pushes the center column 7 to move. Since the guide column 10 on the inner wall of the inner cavity 5 slides in the guide groove 11 on the outer wall of the center column 7, and the guide groove 11 is a spiral structure, the center column 7 rotates while moving, and the end of the center column 7 will pull the elastic metal part 8 to deform, and while stretching the elastic metal part 8, it will drive one end of the elastic metal part 8 to rotate. Since the elastic metal part 8 is a spiral structure, and one end of the elastic metal part 8 is fixed to the end of the center column 7, and the other end is fixed to the end face of the pin 4, the elastic metal part 8 contracts during the stretching and rotation process. At this time, the spiral diameter of the middle of the elastic metal part 8 can allow it to pass through the notch of the needle groove 16.

[0053] Then, the connector pin seat 2 is plugged into the connector hole seat 14. When plugging, the card block 19 corresponds to the card slot 20, so that the pin 4 and the socket 15 are docked in order, ensuring the accuracy of the plugging. Figure 11 As shown, the deformed elastic metal piece 8 is inserted into the needle groove 16, and the movable ring 12 is released. Under the elastic recovery effect of the elastic metal piece 8, the elastic metal piece 8 is reset to the position shown in FIG. Figure 10 In the initial state shown, the outer wall of the elastic metal part 8 is tightly fitted against the inner wall of the needle groove 16 to form a conductive circuit, and the nut 17 is rotated onto the threaded sleeve 3 to plug and fix the connector needle seat 2 and the connector hole seat 14 to complete the disassembly. When disassembling, the nut 17 is rotated and the movable ring 12 is pushed to complete the disassembly of the connector needle seat 2 and the connector hole seat 14.

[0054] Finally, when the connector is placed on the ground using an electric wire connection, the nut 17 is easily rotated when the connector is dragged on the ground for a long time. Even if the nut 17 is disengaged from the threaded sleeve 3, the front end of the needle groove 16 is a conical structure, and the spiral diameter at the middle of the elastic metal part 8 is larger than the notch of the needle groove 16, the pin 4 cannot be separated from the socket 15, which further improves the plug-in stability of the connector when in use. Secondly, in the process of the elastic metal part 8 being inserted into the needle groove 16, the structural characteristics of the elastic metal part 8 itself are used to reduce the wear caused by hard friction during plug-in, thereby increasing the service life.
