Description

Technical Field

[0001] The present invention belongs to the technical field of connectors, and more specifically, particularly relates to a wiring harness connector with a retractable structure. Background Art

[0002] A wiring harness connector is an electronic component used to connect wires, wires or wiring harnesses. A wiring harness connector can transmit electrical signals between different circuits or devices to ensure accurate and stable signal transmission. For example, in automotive electronic systems, various sensors and control units transmit signals through wiring harness connectors to achieve various functions of the vehicle, such as engine control, brake system signal transmission, etc. In addition to transmitting signals, it can also transmit current to provide power support for equipment or circuits. In some high-power equipment, such as industrial electrical control systems, wiring harness connectors need to be able to withstand larger currents to ensure the normal operation of the motor.

[0003] 1. When the existing connector is in use, it needs to be connected to other components for circuit wiring. Since the circuit belongs to a concealed project, the wiring is required to be horizontal and vertical. At the same time, because the staff needs to cut the length of each wire connected by wire strippers according to their own experience, it is easy to make the length of the wires connected to the connector unable to meet the horizontal and vertical process requirements during wiring. The staff needs to change the wires or shorten the length of the wires for adjustment and rework, which is troublesome and lacks practicality and needs to be improved;

[0004] 2. When wiring, the existing connector needs to ensure that the wiring is horizontal and vertical. When wiring, the staff cuts the wires according to their experience, which is difficult for novices to use. It is easy to cause the wires to be too short and unable to connect. It is difficult and lacks practicality, and needs to be improved.

[0005] 3. When the existing connector is connected, the length of the connector after being connected to other components is usually adapted, and it is impossible to ensure that the circuit is horizontal and vertical while leaving excess wires in the connector. Therefore, if the end of the wire is damaged, the entire wire usually needs to be replaced, which is easy to cause waste and lacks practicality, and needs to be improved;

[0006] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a wiring harness connector with a retractable structure is provided, in order to achieve the purpose of having more practical value. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides a wiring harness connector with a retractable structure to solve the above problems.

[0008] A wiring harness connector with a retractable structure comprises a wiring harness connector body, wherein the upper end of the wiring harness connector body is provided with a stepped groove:

[0009] The side wall of the stepped groove is symmetrically threaded with a retractable structure;

[0010] The retractable structure includes side plates, both of which are provided with square grooves, and protective covers are threadedly installed on the side walls of the stepped grooves. Sliders are slidably installed in the two square grooves, and a first sliding column, a second sliding column and a third sliding column are provided between the two slides. The second sliding column is located between the first sliding column and the third sliding column, and T-shaped grooves are provided in the first sliding column, the second sliding column and the third sliding column, and the number of T-shaped grooves provided on the second sliding column is greater than the number of T-shaped grooves provided on the first sliding column and the third sliding column.

[0011] Preferably, double T-shaped blocks are slidably installed between the T-shaped grooves on the first sliding column and the second sliding column and between the T-shaped grooves on the second sliding column and the third sliding column, U-shaped plates are fixedly installed on the circumferential surfaces of the first sliding column, the second sliding column and the third sliding column, a connecting rod is fixedly installed between the two step grooves, the connecting rod is located on the inner sides of the first sliding column, the second sliding column and the third sliding column, the shape of the combination of the two side plates and the connecting rod is "H" shape, and a plurality of springs are fixedly installed on the side walls of the connecting rod.

[0012] Preferably, each of the spring circumferential surface is provided with a connecting end, each of the spring and the connecting end are parallel to the U-shaped plates on the first sliding column, the second sliding column and the third sliding column, each of the U-shaped plates is fixedly mounted with a side block on the side wall, and each of the side blocks is on the same side as the connecting rod.

[0013] Preferably, each of the side blocks is provided with a through slot, each of the inner walls of the through slot is symmetrically provided with a clamping slot, each of the side walls of the connecting end is fixedly mounted with a rectangular block, each of the upper and lower ends of the rectangular block is fixedly mounted with a clamping block, each of the rectangular blocks is slidably mounted inside the through slot, each of the clamping blocks is clamped inside the clamping slot, each of the U-shaped plates is symmetrically fixedly mounted with a rubber block, each of the side walls of the rubber block is provided with an oblique slot, and each of the side walls of the oblique slot is fixedly mounted with a sawtooth group.

[0014] Preferably, the inner walls of the two square grooves are symmetrically provided with second limit grooves, a limit block is slidably installed inside each of the second limit grooves, the two sliders are located between the limit blocks, the two sliders are fixedly installed with the limit blocks, and a plurality of input ports are arranged on the side wall of the wiring harness connector body.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, by pulling and picking up one end of the connecting end in the spring, the clamping state of the rectangular block and the clamping block in the through groove and the clamping groove on the side block can be controlled, so that it can be determined whether the pressure applied by the spring needs to be applied to the first sliding column, the second sliding column and the third sliding column according to the current connection status of the wiring harness connector body, thereby avoiding the influence of the retractable structure on the normal wiring of the staff and improving flexibility.

[0017] In the present invention, by optimizing the structure and layout of the device, the retractable structure is installed on the side panel as a whole, and because the side panel and the wiring harness connector body are threadedly installed, the retractable structure as a whole is convenient for retrofitting on the existing basis, with low modification cost, strong promotion and practicality.

[0018] In the present invention, when wiring, the leads from the output ports of other components are wound around the inside of the rubber block and connected to the input port, so that when subsequent workers insert the rectangular block and the card block into the through groove and the card groove on the side block, they can pull the first sliding column, the second sliding column and the third sliding column to drive the slider and the limit block to slide toward the side of the connecting rod inside the square groove and the second limit groove, and then the wires can be pulled to make the wires taut, which is beneficial to ensure the horizontal and vertical state of the circuit when wiring, and there is no need to rework due to the excessive length of the wires, thereby improving practicality.

[0019] In the present invention, since each wire connected to the input port is cut to a length based on the staff's experience, the length of each wire has a certain error, and since the tension between the first sliding column, the second sliding column and the third sliding column is applied by each individual spring, when there is an error in the length of some wires, the spring will actively pull the first sliding column, the second sliding column or the third sliding column to move, so that the T-slot inside the first sliding column, the second sliding column or the third sliding column actively slides with the double T-block, thereby ensuring that each wire can be in a taut state and improving flexibility.

[0020] In the present invention, by setting a limit block and a second limit groove, when the first sliding column, the second sliding column and the third sliding column drive the sliding block to move in the square groove, the limit block will be driven to slide toward the side of the connecting rod inside the second limit groove, thereby providing limitation and increasing stability.

[0021] In the present invention, by setting up a retractable structure, the staff can reduce the worry about rework caused by long wires, thereby reducing the wiring difficulty of the staff and reducing the problem of rework, and thus indirectly avoiding waste, and further solving various problems that occur when the wiring harness connector body is connected, which is more practical.

DETAILED DESCRIPTION

[0035] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] See also Figure 1 - Fig.12 The present invention provides a wiring harness connector with a retractable structure, including a wiring harness connector body 11, and a stepped groove 12 is provided at the upper end of the wiring harness connector body 11:

[0037] The side wall of the stepped groove 12 is symmetrically threaded with a retractable structure;

[0038] The retractable structure includes a side plate 13, a square groove 14 is formed inside the two side plates 13, a protective cover 38 is threadedly installed on the side wall of the stepped groove 12, a slider 15 is slidably installed inside the two square grooves 14, a first sliding column 16, a second sliding column 17 and a third sliding column 18 are provided between the two sliders 15, the second sliding column 17 is located between the first sliding column 16 and the third sliding column 18, a T-shaped groove 19 is formed inside the first sliding column 16, the second sliding column 17 and the third sliding column 18, the number of the T-shaped grooves 19 formed on the second sliding column 17 is greater than the number of the T-shaped grooves 19 formed on the first sliding column 16 and the third sliding column 18, and the retractable structure is installed on the side plate 13 as a whole by optimizing the structure and layout of the device, and because the side plate 13 and the line The harness connector body 11 is threadedly installed, so that the overall retractable structure is easy to install on the existing basis, with low modification cost, strong promotion and practicality. By setting up the retractable structure, the staff can significantly reduce the rework problem caused by leaving the wire too long when performing wiring operations. The use of this structure can greatly reduce the difficulty and pressure of the staff during the wiring process, and avoid worrying about connection errors or inaccuracies caused by too long cables. In this way, the number of reworks can be reduced, thereby indirectly avoiding the waste of resources. The retractable structure can also effectively solve the various problems encountered by the harness connector body 11 in the actual connection process, making the entire connection process smoother and more efficient, and improving work efficiency and practicality.

[0039] A double T-shaped block 21 is slidably installed between the T-shaped slots 19 on the first sliding column 16 and the second sliding column 17 and between the T-shaped slots 19 on the second sliding column 17 and the third sliding column 18. A U-shaped plate 22 is fixedly installed on the circumferential surfaces of the first sliding column 16, the second sliding column 17 and the third sliding column 18. A connecting rod 23 is fixedly installed between the two step grooves 12. The connecting rod 23 is located on the inner side of the first sliding column 16, the second sliding column 17 and the third sliding column 18. The shape of the combination of the two side plates 13 and the connecting rod 23 is "H" shape. A plurality of springs 24 are fixedly installed on the side wall of the connecting rod 23. Since each wire connected to the input port 37 is cut and connected according to the experience of the staff, the length of these wires will inevitably have a certain error. At the same time, due to the first The pulling force between the first sliding column 16, the second sliding column 17 and the third sliding column 18 is applied by each individual spring 24. Therefore, when there is an error in the length of part of the wire, the spring 24 will actively pull the first sliding column 16, the second sliding column 17 or the third sliding column 18 to move accordingly. This movement enables the T-slot 19 inside the first sliding column 16, the second sliding column 17 or the third sliding column 18 to actively slide with the double T-block 21, thereby ensuring that each wire can be in a taut state, which not only improves the flexibility of the wire, but also ensures the entire circuit process requirements. Through the retractable structure, even if there is an error in the length of each wire, the retractable structure can keep the wire in a taut state through the adjustment mechanism, and has strong flexibility and practicality.

[0040] Each spring 24 is provided with a connecting end 25 on its circumferential surface. Each spring 24 and the connecting end 25 are parallel to the U-shaped plate 22 on the first sliding column 16, the second sliding column 17 and the third sliding column 18. A side block 26 is fixedly installed on the side wall of each U-shaped plate 22. Each side block 26 is on the same side as the connecting rod 23. A through groove 27 is opened inside each side block 26. A slot 28 is symmetrically opened on the inner wall of each through groove 27. A rectangular block 29 is fixedly installed on the side wall of each connecting end 25. A clamping block 31 is fixedly installed at the upper end and the lower end of each rectangular block 29. Each rectangular block 29 is slidably installed inside the through slot 27. Each clamping block 31 is clamped inside the clamping slot 28. A rubber block 32 is symmetrically fixedly installed on the inner side of each U-shaped plate 22. An oblique groove 33 is opened on the side wall of each rubber block 32. A sawtooth group 34 is fixedly installed on the side wall of each oblique groove 33. When wiring, the leads from the output ports of the remaining components are wound around the rubber block 32 and the sawtooth group 34.

[0041] The internal access input port 37 allows subsequent staff to pull the first sliding column 16, the second sliding column 17 and the third sliding column 18 to drive the slider 15 and the limit block 36 to slide toward the side of the connecting rod 23 inside the square groove 14 and the second limit groove 35 when inserting the rectangular block 29 and the card block 31 into the through groove 27 and the card groove 28 on the side block 26, so that the wires can be pulled to make the wires taut, which is beneficial to ensure the horizontal and vertical state of the circuit wiring, and there is no need to rework due to the excessive length of the wires, thereby improving practicality.

[0042] The inner walls of the two square grooves 14 are symmetrically provided with second limit grooves 35, and a limit block 36 is slidably installed inside each second limit groove 35. The two sliders 15 are located between the limit blocks 36, and the two sliders 15 are fixedly installed with the limit blocks 36. A plurality of input ports 37 are provided on the side wall of the wiring harness connector body 11. By providing the limit blocks 36 and the second limit grooves 35, when the first sliding column 16, the second sliding column 17 and the third sliding column 18 drive the slider 15 to move in the square groove 14, the limit block 36 will be driven to slide toward the side of the connecting rod 23 inside the second limit groove 35, thereby providing a limit and increasing stability.

[0043] Working principle:

[0044] The first step is the preparation and wiring of the wiring;

[0045] During the assembly process of electronic equipment, it is necessary to connect the leads on the output ports of some components to the wiring harness connector body 11. First, the staff removes the protective cover 38 from the stepped groove 12. Then the staff first needs to pick up one end of the connecting end 25 in the spring 24, and then needs to move the connecting end 25 to the side of the opening in the card slot 28. In this process, the connecting end 25 will generate a radial force, which will drive the rectangular block 29 and the card block 31 to slide outward inside the through groove 27 and the card slot 28 on the side block 26. In this way, the force of the spring 24 will stop moving toward the first sliding column 16, the second sliding column 17 and the third sliding column. Pressure is applied on the column 18. Subsequently, the staff can bypass the wires to be connected from above the first sliding column 16, the second sliding column 17 and the third sliding column 18 respectively, and introduce these wires into the rubber blocks 32 inside the double T-shaped blocks 21 on the first sliding column 16, the second sliding column 17 and the third sliding column 18. Then, the wires can be connected to the input port 37 respectively. However, in the actual wiring process, in order to avoid insufficient wire length, a certain amount of extra length is usually reserved. Therefore, when the leads from the output ports of the remaining components are wound around the rubber block 32 and connected to the input port 37, the wires will be in a somewhat loose state.

[0046] In the second step, the retractable structure tightens the line;

[0047] Then the staff can pick up one end of the connecting end 25 on each spring 24 again, and insert the rectangular block 29 and the card block 31 into the input port 37 and the card slot 28 on the side block 26 again, so that the spring 24 will apply force to each U-shaped plate 22 individually, and then the spring 24 will generate a radial force on the first sliding column 16, the second sliding column 17 and the third sliding column 18 as a whole, so that the first sliding column 16, the second sliding column 17 and the third sliding column 18 drive the slider 15 and the limit block 36 to slide toward the side of the connecting rod 23 inside the square groove 14 and the second limit groove 35, so as to pull the wires so that each wire is in a taut state.

[0048] In the third step, the first sliding post 16, the second sliding post 17 or the third sliding post 18 in the retractable structure will tighten each wire individually;

[0049] Since each wire connected to the input port 37 is cut and connected based on the staff's experience, there will inevitably be a certain error in the length of each wire. In addition, since the tension between the first sliding column 16, the second sliding column 17 and the third sliding column 18 is applied by each individual spring 24, when there is an error in the length of some wires, the spring 24 will actively pull the first sliding column 16, the second sliding column 17 or the third sliding column 18 to move accordingly. This movement causes the T-slot 19 inside the first sliding column 16, the second sliding column 17 or the third sliding column 18 to actively slide with the double T-block 21, thereby ensuring that each wire can be in a taut state and ensuring the horizontal and vertical process requirements of the circuit. The staff then installs the protective cover 38 on the stepped groove 12 with screws to complete the wiring.

[0050] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
