Description

Technical Field

[0001] The invention relates to the technical field of wiring connectors, in particular to a quick-assembly wiring connector. Background Art

[0002] A wiring connector is an electronic component used to connect the end of a cable or wiring harness to other cables, wiring harnesses or devices. It plays a vital role in electronic, electrical and automation systems, ensuring the reliable transmission of signals and power. At the same time, the wiring connector has good anti-interference performance and is suitable for various environments, including high temperature, low temperature, high humidity and other harsh environments, reducing the impact of electromagnetic interference on the system and providing protection for the connection of the wires.

[0003] The Chinese patent with announcement number CN112864675B discloses a wiring connector and its extraction tool, including a male connector and a female connector; the male connector can be plugged into the female connector from two directions, and the conductive clip can not only connect the wire and the solder pin, but also abut the test probe; the extraction tool is a matching tool that can easily separate the plugged female connector from the male connector without causing damage to the wiring connector.

[0004] A Chinese patent with announcement number CN207883940U discloses a junction box with convenient wiring, including a connecting part and a wire clamping part; when the core wire is inserted into the wire clamping groove through the wiring hole, the tensioning force of the wiring terminal can clamp the core wire, and pierce the core wire skin through the wire clamping groove to conduct the connection, thereby making the junction box very convenient to use.

[0005] The above and similar prior arts can solve the connection problem of wires to a certain extent, but the traditional junction box assembly process requires multiple steps, which are cumbersome and require professional skills, resulting in low assembly efficiency.

DETAILED DESCRIPTION

[0030] In order to make the technical means, technical features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] Example: Figure 1-Figure 9 As shown, a quick assembly wiring connector described in the present invention includes a shell 1, on which a number of plug interfaces 2 and wiring holes 3 are provided, and plug terminals 4 and wiring terminals 5 are provided between the plug interfaces 2 and the wiring holes 3. The shell 1 is provided with a plug interface 2 on a side away from the wiring hole 3, and the plug interface 2 is communicated with the wiring hole 3, the plug terminal 4 is located on the inner side of the plug interface 2 and the wiring hole 3, the plug terminal 4 is detachable, the wiring terminal 5 is located at the bottom of the plug terminal 4, and there are multiple tips on the top of the wiring terminal 5, and limiting columns 51 are fixedly installed on both sides of the wiring terminal 5, respectively, and the inner walls on both sides of the wiring hole 3 are provided with slide grooves 6, and the inner sides of the top wall and the bottom wall of the slide groove 6 are respectively provided with limiting grooves 7, and the end of the slide groove 6 facing the outside is provided with a guide groove, and the other end of the slide groove 6 is provided with a receiving groove 8, and the limiting column 51 is located on the inner side of the receiving groove 8, and the shell 1 is provided with multiple card interfaces 9 on the side close to the wiring hole 3.

[0032] Specifically, the housing 1 can provide a space for the wiring hole 3 and the plug interface 2, the wiring hole 3 can provide a connection space for external wires, the plug interface 2 can provide a plug-in function for external wires, the wiring hole 3 is in an I-shape, the top notch of the wiring hole 3 can provide an installation space for the plug-in terminal 4, the bottom notch of the wiring hole 3 can provide an installation space for the wiring terminal 5, the wiring terminal 5 can provide a stable support for the limit column 51, the wiring hole 3 can provide a space for the slide groove 6, and the guide port can provide a guiding function to facilitate the installation of the wiring terminal 5 and the slider 221. When installing the wiring terminal 5, the wiring terminal 5 needs to be compressed before entering the wiring hole 3, so that the limiting column 51 can enter the inner side of the slide groove 6 through the guide groove, so that the wiring terminal 5 enters the inner side of the wiring hole 3 in a compressed state. When the limiting column 51 enters the inner side of the storage groove 8, the wiring terminal 5 stretches out, so that the pointed top of the wiring terminal 5 contacts the bottom of the plug-in terminal 4, preventing the top of the wiring terminal 5 from contacting one end of the plug-in terminal 4 in advance during the installation process, resulting in the wiring terminal 5 being unable to enter the fixed installation position, thereby facilitating the assembly of the wiring terminal 5.

[0033] In this embodiment, the external connection part 10 is detachably mounted on the side of the housing 1 where the wiring hole 3 is opened. A card plate 11 is provided on the side of the external connection part 10 close to the housing 1. The card plate 11 is located on the inner side of the card interface 9. A plurality of push plates 12 are fixedly installed on the side of the external connection part 10 close to the housing 1. The push plates 12 are located on the inner side of the wiring hole 3 and contact one end of the plug terminal 4. The interior of the external connection part 10 is penetrated by a comparison hole 13 corresponding to the wiring hole 3. The comparison hole 13 The inner walls on both sides are respectively provided with rotating grooves 14, and a fixing rod 15 is fixedly installed on the inner side of the rotating groove 14. A plurality of movable grooves 16 are provided inside the external connection part 10, and two symmetrical arc holes 17 are provided at the bottom of the movable groove 16, which are communicated with the control hole 13. Another plurality of arc holes 17 are provided on the top of the external connection part 10, and the arc holes 17 are communicated with the movable groove 16. A column groove 18 is provided on the side of the push plate 12 close to the external connection part 10, and the column groove 18 is communicated with the movable groove 16.

[0034] Specifically, the external connection part 10 can provide a stable support for the push plate 12. When the external connection part 10 is installed, the push plate 12 can press against one end of the plug-in terminal 4 to squeeze the plug-in terminal 4 to limit the position, so that the plug-in terminal 4 can be fixed in the installation position. The external connection part 10 can provide a through-opening space for the reference hole 13, and the reference hole 13 can provide a rotation space for the rotating door 191. The reference hole 13 can provide an opening space for the rotating groove 14, and the rotating groove 14 can provide a storage space for the rotating door 191. When the rotating door 191 is rotated to both sides to open, the rotating door 191 can be rotated to the inner side of the rotating groove 14, so that the rotating door 191 and the reference hole 13 can be opened. The inner walls on both sides of the hole 13 are aligned to reduce obstacles to the entry and exit of the wires. The fixed rod 15 can provide rotational support for the rotating plate 20. The external connection part 10 can provide opening space for the movable groove 16 and the arc hole 17. The movable groove 16 can provide movable space for the synchronous plate 196. The arc hole 17 can provide a guiding function for the fixed column 195. When the rotating plate 20 drives the longer fixed column 195 to rotate, the longer fixed column 195 can drive the shorter fixed column 195 to move through the synchronous plate 196. The shorter fixed column 195 rotates under the limiting guiding action of the arc hole 17, and then can drive the two rotating doors 191 to rotate and open through the rotating plate 20.

[0035] In this embodiment, the wiring locking mechanism 19 is rotatably connected to the inner side of the rotating groove 14 through the fixed rod 15. The wiring locking mechanism 19 includes a rotating door 191, and a rotating groove 194 is provided inside the rotating door 191. The inner side of the rotating groove 194 is rotatably connected to the extrusion mechanism 22 through the connecting rod 21. The rotating door 191 is rotatably mounted on the outer side of the fixed rod 15. A wire clamping groove 192 is provided on one side of the rotating door 191. A plurality of extrusion protrusions 193 are fixedly installed on the inner side of the wire clamping groove 192. Two rotating doors 191 are located on the inner side of a comparison hole 13 as a group. The tops of the two rotating doors 191 of each group are respectively fixedly installed with fixed columns 195, and the two fixed columns 195 are respectively located on the inner sides of the two symmetrical arc holes 17 at the bottom of the movable groove 16. The two fixed columns 195 have different lengths. The longer fixed column 195 passes through the inner side of the movable groove 16 and the arc hole 17 at the top of the external connection part 10. A synchronous plate 196 is placed on the inner side of the movable groove 16. Two sliding holes are symmetrically penetrated inside the synchronous plate 196, and the two sliding holes of the synchronous plate 196 are respectively located on the outer sides of the two fixed columns 195. A reset rod 197 is fixedly installed on one side of the synchronous plate 196. One end of the reset rod 197 is located on the inner side of the column groove 18. A reset spring 198 is fixedly installed on one end of the reset rod 197 away from the synchronous plate 196, and the reset spring 198 is located on the inner side of the column groove 18. A plurality of rotating plates 20 are rotatably installed on the top of the external connection part 10, and the rotating plates 20 are respectively rotatably mounted on the outer sides of the longer fixed columns 195.

[0036] Specifically, the transmission component is used to drive the wiring locking mechanism to loosen or clamp the connection line. The transmission component is a rotating plate 20. The rotating door 191 can provide a space for the wire clamping groove 192. The wire clamping groove 192 can provide a placement space for the wire. The wire clamping groove 192 can provide a stable support for the extrusion protrusion 193. When the wire clamping groove 192 is wrapped around the outside of the wire, the extrusion protrusion 193 squeezes the skin of the wire to compress and deform, thereby providing friction for the wire to prevent the wire from relative displacement with the rotating door 191. When the two rotating doors 191 rotate to the overlapping position, they are resisted by the arc hole 17 and the fixed column 195. , and the resistance of the rotating door 191 to the rotating slot 14 makes it impossible for the rotating door 191 to continue to rotate toward the front, and cooperates with the extrusion protrusion 193 to fix the wire to prevent the wire from being pulled out of the inner side of the shell 1 when it is pulled by external force, which can reduce the damage to the components inside the shell 1 and the failure of the connector caused by external force. The synchronization plate 196 can provide a stable support for the reset rod 197, and the reset rod 197 can provide a stable support for the reset spring 198. When the rotating plate 20 loses the external force, the reset spring 198 can push the two rotating doors 191 to return to the overlapping position, which is convenient for the installation of the wire.

[0037] In this embodiment, a second rotating groove 194 is provided inside the rotating door 191, and the inner side of the second rotating groove 194 is connected to a squeezing mechanism 22 through a connecting rod 21; the squeezing mechanism 22 is used to squeeze the upper part of the wiring terminal 5 so that the top of the wiring terminal 5 is away from the top of the wiring hole 3, and the squeezing mechanism 22 includes two sliders 221, and the two sliders 221 are respectively slidably installed on the inner sides of the two slide grooves 6 of the wiring hole 3, and the top and bottom of the sliders 221 are respectively fixedly installed with limit plates 222, and the limit plates 222 are located on the inner side of the limit groove 7. A hinge groove 223 is provided on the side of the slider 221 close to the external connection part 10, and is rotatably connected to one end of the connecting rod 21 through the hinge groove 223. A push rod 224 is fixedly installed between the two sliders 221, and a rolling tube 225 is rotatably installed on the outer side of the push rod 224.

[0038] Specifically, the slider 221 can provide a space for opening the hinge groove 223. There is a round rod on the inner side of the hinge groove 223, and the round rod can cooperate with the connection to realize a rotation connection. The slide groove 6 can not only provide a sliding space for the slider 221, but also provide a storage space for the connecting rod 21. When the rotating door 191 rotates and drives the slider 221 to move through the connecting rod 21, the rotating door 191 rotates 90°, and the connecting rod 21 completely enters the inner side of the slide groove 6, reducing the obstruction to one end of the wire. The slider 221 can provide a stable support for the push rod 224, and the push rod 224 can provide a driving force for the rolling tube 225. When the slider 221 drives the rolling tube 225 to squeeze the terminal 5 through the push rod 224, the rolling tube 225 rotates under the friction force of the terminal 5, and the static friction of the push rod 224 on the terminal 5 is converted into the rolling friction of the rolling tube 225, so that the relative movement of the push rod 224 and the terminal 5 is smoother.

[0039] Working principle: When assembling, the staff first slides the top part of the plug-in terminal 4 along the inner side of the top wall of the I-shaped wiring hole 3, and installs multiple plug-in terminals 4 one by one on the inner side of the wiring hole 3, then grabs the wiring terminal 5 and presses it to reduce the angle between the wiring terminals 5, and inserts the limiting columns 51 on both sides of the wiring terminal 5 along the inner side of the guide groove, so that the limiting columns 51 slide along the inner side of the slide groove 6. When the limiting columns 51 move to the inner side of the storage groove 8, the wiring terminal 5 loses the extrusion reset due to the limiting columns 51, so that the pointed part of the wiring terminal 5 abuts against the bottom of the plug-in terminal 4, and finally aligns the side of the external connection part 10 with the clamping plate 11 to the side of the housing 1 with the clamping interface 9, and at the same time pushes the slider 221 in the direction of the guide groove, and uses the clamping action of the clamping plate 11 and the clamping interface 9 to install the external connection part 10 on the front side of the housing 1;

[0040] Then the staff installs the wire, first grabs the rotating plate 20 and rotates it, so that the rotating plate 20 drives the longer fixed column 195 to rotate along the inner side of the arc hole 17 at the top of the external connection part 10, and the longer fixed column 195 slides along the inner side of the sliding hole of the synchronous plate 196, and drives the synchronous plate 196 to move in the direction close to the housing 1, and the synchronous plate 196 is compressed by the reset rod 197 to squeeze the reset spring 198, so that the synchronous plate 196 drives the shorter fixed column 195 to move, and the two fixed columns 195 rotate along the inner side of the symmetrically opened arc hole 17. When the fixed column 195 rotates, it will drive the rotating door 191 to rotate together, so that the rotating door 191 rotates and opens with the fixed rod 15 as the center of the circle, and the rotating door 191 rotates 90° to enter the inner side of the rotating groove 14, and at the same time, the rotating door 191 rotates and drives the slide to slide along the inner side of the slide groove 6 through the connecting rod 21, so that the slider 221 drives the push rod 224 and the rolling tube 225 to move in the direction of the terminal 5, and the rolling tube 225 The terminal 5 contacts the surface of the wiring terminal 5 and drives the wiring terminal 5 to be compressed, so that the angle of the wiring terminal 5 is reduced. The discontinuous end of the wiring terminal 5 is away from the bottom of the plug-in terminal 4, leaving a certain gap. The staff moves one end of the external wire through the reference hole 13 and the wiring hole 3 to between the plug-in terminal 4 and the wiring terminal 5, and loosens the rotating turn plate 20. The reset spring 198 and the wiring terminal 5 are reset after losing the external force, and the rotating door 191 is pushed to close again. The rotating door 191 is not completely closed due to the obstruction of the wire. The wiring terminal 5 is unfolded so that the end with the tip cooperates with the plug-in terminal 4 to clamp the wire. Finally, the wire is pulled away from the housing 1, so that the tip of the wiring terminal 5 is inserted into the inner side of the wire and connected with the wire. At the same time, the friction between the wire and the wire clamping groove 192 rotates the two rotating doors 191 to the overlapping position, and the rotating door 191 is completely closed. The rotating door 191 uses the extrusion protrusion 193 to squeeze the wire to fix the wire;

[0041] When the wire needs to be removed, the rotating plate 2090° can be rotated again to rotate the rotating door 191 90° to the inner side of the rotating groove 14, and the rotating door 191 is fully opened, so that the terminal 5 no longer squeezes the wire. The wire is first pushed to the inner side of the wiring hole 3, and the wire is separated from the tip of the terminal 5 and then moved out to complete the removal of the wire.
