[0002] A wire harness is a wiring component that connects various electrical devices in a circuit and is widely used in multiple fields such as automobiles, motorcycles, household appliances, and mechatronics. When a wire harness is applied between various electrical devices, a wire harness connector is usually required, and the wire harness is inserted into the wire harness connector.

[0003] In the related art, it is necessary to insert a wire harness connector into a preset mounting hole on an electrical component, and the wire harness connector is in interference fit with the mounting hole to ensure the sealing performance and mounting reliability. Operators need to use tools such as hammers to knock the wire harness connector into the mounting hole. During the knocking process, fingers may be injured due to lack of fixation, and it is not easy to position, resulting in difficult assembly and affecting production efficiency. Summary of the Utility Model

[0004] In view of this, the utility model provides a pressing tooling to solve the problems of easy finger injury and difficult assembly.

[0005] The utility model provides a pressing tooling applicable to a wire harness connector, including: a wire harness receiving tube for pressing the wire harness connector. The wire harness receiving tube is provided with an inlet, an outlet, and an avoidance port. The inlet, the avoidance port, and the outlet are communicated.

The avoidance port penetrates through one end of the wire harness receiving tube for pressing the wire harness connector, and the avoidance port is used to avoid the card of the wire harness connector.

[0006] Beneficial effects: By using the pressing tooling to press the wire harness connector, operators do not need to directly support the wire harness connector. Instead, they use tools such as hammers to knock the pressing tooling. Compared with directly supporting the wire harness connector, the operating space of the operator's hand is larger, which can reduce the probability of finger injury, reduce the assembly difficulty, and improve the production efficiency. In addition, the avoidance port is used to avoid the card of the wire harness connector, which can prevent the pressing tooling from directly pressing on the card, avoid damaging the card, ensure the structural integrity of the wire harness connector, ensure that the wire harness connector can be used normally, and can improve the positioning accuracy between the pressing tooling and the wire harness connector, further reducing the assembly difficulty and improving the production efficiency.

[0007] In an optional embodiment, the pressing tooling further includes: an operating part connected to the end of the wire harness receiving tube far from the inlet, and the outer surface of the operating part is configured as a cylinder.

[0008] Beneficial effects: By constructing the outer surface of the operating part into a cylindrical shape, the area where the operating part can be clamped is large, which is beneficial to improving the stability of the press-fitting tooling.

The outlet port is provided on the circumferential surface of the outlet section, and the outlet port is communicated with the avoidance port.

[0014] Beneficial effects: While ensuring the connection between the operating part and the wire harness accommodating tube, it can avoid the influence of the operating part on the wire harness routing, and ensure the smoothness of the wire harness routing in the wire harness accommodating tube. Moreover, since the outlet port is communicated with the avoidance port, the outlet port and the avoidance port can be formed in one processing, which is more convenient for processing and improves production efficiency.

[0015] In an alternative embodiment, the outlet port penetrates through both axial ends of the outlet section.

[0016] Beneficial effects: The area of the outlet port is large, which is convenient for the wire harness to extend out of the outlet port. Moreover, the outlet port is convenient for processing and manufacturing, which improves processing efficiency. In addition, the material used for the outlet section can be reduced, the weight can be reduced, the cost can be reduced, and it is convenient for the operator to pick up and use.

[0017] In an alternative embodiment, the arc length of the outlet section is less than the arc length of the inlet section.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0038] The following combines Figures 1 to 6 , to describe the embodiments of the present utility model.

[0039] According to an embodiment of the present utility model, a press-fitting tooling 1 is provided. The press-fitting tooling 1 is applicable to a wire harness connector 2, and the press-fitting tooling 1 includes a wire harness receiving tube 100.

[0040] The wire harness receiving tube 100 is used to press the wire harness connector 2. The wire harness receiving tube 100 is provided with a receiving cavity 104, an inlet 101, an outlet 102, and an avoidance port 103. Both the inlet 101 and the outlet 102 are communicated with the receiving cavity 104, and the inlet 101 is communicated with the avoidance port 103. The inlet 101 is arranged at one end of the wire harness receiving tube 100 for pressing the wire harness connector 2, and the avoidance port 103 is arranged on the circumferential surface of the wire harness receiving tube 100. The avoidance port 103 penetrates through one end of the wire harness receiving tube 100 for pressing the wire harness connector 2, and the avoidance port 103 is used to avoid the card 21 of the wire harness connector 2.

[0041] For example, the card 21 of the wire harness connector 2 can be made of plastic material. The card 21 can be used as a handle, which is convenient for the disassembly and installation of the wire harness connector 2 and can play a positioning role.

[0042] The wire harness 3 connected to the wire harness connector 2 enters the receiving cavity 104 through the inlet 101 and then extends out of the receiving cavity 104 through the outlet 102. That is to say, a part of the wire harness 3 is located in the receiving cavity 104. The wire harness receiving tube 100 can play a role in protecting the wire harness 3, reducing the probability of the wire harness 3 being worn during the installation process of pressing and installing the wire harness connector 2 with the press-fitting tooling 1, and ensuring the integrity and effectiveness of the wire harness 3.

[0043] By using the press-fitting tooling 1 to press the wire harness connector 2, the operator does not need to directly support the wire harness connector 2. Tools such as a hammer can be used to strike the press-fitting tooling 1. Compared with directly supporting the wire harness connector 2, the operator has a larger movement space for the hand, which can reduce the probability of hitting the finger, reduce the assembly difficulty, and improve the production efficiency.

[0044] Since the inlet 101 is provided at one end of the wire harness accommodating tube 100 that presses the wire harness connector 2, the distance between the inlet 101 and the wire harness 3 is relatively close in this way, and the wire harness 3 can extend into the inlet 101 without being bent, avoiding damage to the wire harness 3 caused by bending.

[0045] In addition, the avoidance port 103 is used to avoid the card 21 of the wire harness connector 2, which can prevent the pressing tooling 1 from directly pressing on the card 21, avoid damaging the card 21, ensure the structural integrity of the wire harness connector 2, so as to ensure that the wire harness connector 2 can be used normally, and can improve the positioning accuracy between the pressing tooling 1 and the wire harness connector 2, further reducing the assembly difficulty and improving the production efficiency.

[0046] As Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the pressing tooling 1 further includes an operation part 200, and the operation part 200 is connected to the end of the wire harness accommodating tube 100 far from the inlet 101, and the outer surface of the operation part 200 is configured as a cylinder. Among them, the operator can hold the operation part 200 by hand or clamp the operation part 200 through other devices.

[0047] By configuring the outer surface of the operation part 200 as a cylinder, the operation part 200 can have a large clamping area, which is beneficial to improving the stability of the pressing tooling 1, and the reaction force exerted by the operation part 200 on the hand is relatively uniform, and the operator's hand will not be fatigued or painful.

[0048] As Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the operation part 200 is provided with a weight-reducing cavity 210, and the weight-reducing cavity 210 extends along the axial direction of the operation part 200. Among them, the central axis of the weight-reducing cavity 210 and the central axis of the operation part 200 can be arranged to coincide. In this way, the weight of the pressing tooling 1 can be reduced, which is convenient for the operator to pick up and use, and the cost is reduced.

[0049] As Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the weight-reducing cavity 210 penetrates through both axial ends of the operation part 200. In this way, the weight of the pressing tooling 1 can be further reduced, which is convenient for the operator to pick up and use, and the cost is further reduced. In addition, the weight-reducing cavity 210 and the accommodating cavity 104 of the wire harness accommodating tube 100 can be communicated and can be formed in one step, which is more convenient for processing and improves the processing efficiency.

[0050] As Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the wire harness accommodating tube 100 includes an inlet segment 110 and an outlet segment 120.

[0051] The inlet segment 110 is used to press the wire harness connector 2. The inlet port 101 is provided at one end of the inlet segment 110 for pressing the wire harness connector 2. The avoidance port 103 is provided on the circumferential surface of the inlet segment 110. The avoidance port 103 penetrates through both axial ends of the inlet segment 110. The outlet segment 120 is connected between the inlet segment 110 and the operation part 200. The outlet port 102 is provided on the circumferential surface of the outlet segment 120, and the outlet port 102 communicates with the avoidance port 103.

[0052] By providing the outlet port 102 on the circumferential surface of the outlet segment 120, while ensuring the connection between the operation part 200 and the wire harness accommodating tube 100, it can avoid the influence of the operation part 200 on the routing of the wire harness 3, and ensure the smooth routing of the wire harness 3 within the wire harness accommodating tube 100. Moreover, the outlet port 102 communicates with the avoidance port 103, and the outlet port 102 and the avoidance port 103 can be formed in one processing, which is more convenient for processing and improves production efficiency.

[0053] As Figure 1 and Figure 2 shown, in the technical solution of this embodiment, the outlet port 102 penetrates through both axial ends of the outlet segment 120. In this way, the area of the outlet port 102 is larger, which is convenient for the wire harness 3 to extend out from the outlet port 102, and the outlet port 102 is convenient for processing and manufacturing, improving the processing efficiency. In addition, the material used for the outlet segment 120 can be reduced, the weight can be reduced, the cost can be lowered, and it is convenient for the operator to pick up and use.

[0054] As Figures 1 - 3 shown, in the technical solution of this embodiment, the arc length of the outlet segment 120 is less than the arc length of the inlet segment 110. Among them, the central axis of the outlet segment 120 and the central axis of the inlet segment 110 can be set to coincide.

[0055] In this way, the area of the outlet port 102 is larger, which is convenient for the wire harness 3 to extend out from the outlet port 102, and the material used for the outlet segment 120 can be reduced, the weight can be reduced, the cost can be lowered, and it is convenient for the operator to pick up and use.

[0056] In some embodiments, the central angle corresponding to the outlet segment 120 is less than or equal to 180° to ensure that the area of the outlet port 102 is larger.

[0057] As Figures 1 - 3 shown, in the technical solution of this embodiment, the inlet segment 110 includes a main body 111 and a limit protrusion 112. The side of the main body 111 in the circumferential direction of the wire harness accommodating tube 100 is flush with the side of the outlet segment 120 in the circumferential direction of the wire harness accommodating tube 100. The limit protrusion 112 is provided on the side of the main body 111 in the circumferential direction of the wire harness accommodating tube 100.

[0058] It should be noted that the attached Figure 3The dashed line in indicates the boundary between the limiting protrusion 112 and the main body 111, and does not indicate that the structure corresponding to the above dashed line needs to exist in the actual structure.

[0059] Among them, the limiting protrusion 112 defines the position and structure of the avoidance opening 103. The limiting protrusion 112 cooperates with the card 21 to be able to define the relative position of the press-fitting tool 1 and the wire harness connector 2 in the circumferential direction of the press-fitting tool 1, and improves the positioning accuracy between the press-fitting tool 1 and the wire harness connector 2.

[0060] Such as Figures 1 - 3 As shown, in the technical solution of this embodiment, the inlet segment 110 includes at least two limiting protrusions, and the at least two limiting protrusions are arranged on both sides of the main body 111 in the circumferential direction of the wire harness receiving tube 100. That is to say, at least one limiting protrusion 112 can be arranged on each side of the main body 111 in the circumferential direction of the wire harness receiving tube 100. In this way, the limiting protrusions 112 are located on the opposite sides of the card 21 in the circumferential direction of the press-fitting tool 1, and can further improve the positioning accuracy between the press-fitting tool 1 and the wire harness connector 2.

[0061] Such as Figure 2 As shown, in the technical solution of this embodiment, the inlet segment 110 includes at least two limiting protrusions 112, and the at least two limiting protrusions 112 are arranged at intervals along the axial direction of the wire harness receiving tube 100.

[0062] In this way, during the use of the press-fitting tool 1, in the axial direction of the wire harness receiving tube 100, the limiting protrusion 112 closest to the inlet 101 is first positioned and matched with the card 21. After repeated use, the limiting protrusion 112 closest to the inlet 101 may be deformed, resulting in a reduction in positioning accuracy. At this time, the inlet segment 110 can be cut, and the limiting protrusion 112 closest to the inlet 101 is cut off along the radial direction of the inlet segment 110, so that the limiting protrusion 112 closest to the inlet 101 after cutting is positioned and matched with the card 21, which can ensure the positioning accuracy, extend the service life of the press-fitting tool 1, reduce the replacement frequency of the press-fitting tool 1, and reduce the use cost.

[0063] Such as Figure 4 As shown, in the technical solution of this embodiment, the side of the outlet segment 120 in the circumferential direction of the wire harness receiving tube 100 is configured as an arc. In this way, the side wall around the outlet 102 is relatively smooth, which can reduce the probability of the wire harness 3 being worn at the outlet 102, and avoid the wire harness 3 being cut off at the outlet 102, and improve the service life of the wire harness 3. In addition, during the process of holding or transferring the press-fitting tool 1, the operator may come into contact with the outlet segment 120, which can also prevent the operator from being cut, improve the safety of the press-fitting tool 1, and reduce the probability of accidents.

[0064] The following is an example to illustrate the process of the press-fitting tooling 1 for press-fitting the wire harness connector 2:

[0065] First, pre-assemble the wire harness connector 2 onto the mounting hole of the electrical component;

[0066] Then, insert the wire harness 3 into the receiving cavity 104 through the wire outlet 102 and extend it out of the receiving cavity 104 through the wire outlet 102;

[0067] Next, align the avoidance port 103 with the position of the card 21, and press the press-fitting tooling 1 tightly against the rear end face of the wire harness connector 2;

[0068] Finally, the operator holds the operating part 200 and uses a hammer to strike the end of the operating part 200 away from the wire harness connector 2 to press-fit the wire harness connector 2 into the mounting hole to complete the installation.

[0069] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
