[0001] The present invention relates to the technical field of wiring assembly processing, and in particular to a pressure-maintaining jig. Background Art

[0002] Existing wiring assemblies include cables and connectors arranged at both ends of the cables. Before assembling the wiring assemblies, the cables need to be shaped and bent. Existing bending and pressure-maintaining jigs are not sufficiently applicable to wiring assemblies. Usually, the cables of the wiring assemblies are bent manually. Manual bending has low efficiency, poor precision, and high risk of rebound, and is not suitable for large-scale shaping and assembly of wiring assemblies. Summary of the Invention

[0003] An object of the present invention is to provide a pressure-maintaining jig that can efficiently and reliably bend cables of a wiring assembly while reducing the risk of rebound.

[0004] To achieve this object, the present invention adopts the following technical solutions:

[0005] A pressure-maintaining jig for bending and maintaining pressure on a wiring assembly, wherein the wiring assembly includes a cable, a first connector, and a second connector, wherein the first connector and the second connector are respectively arranged at both ends of the cable, and the pressure-maintaining jig includes:

[0006] Drive device;

[0007] a pressing block, disposed at an output end of the driving device, wherein the driving device is capable of driving the pressing block to move along a first direction, and wherein a counter-pressure groove is provided on the pressing block;

[0008] A support block, wherein a first support surface, a second support surface and a third support surface are sequentially arranged on the support block along a second direction, the second direction is perpendicular to the first direction, and along the first direction, the first support surface, the second support surface and the third support surface are sequentially away from the pressing block, a receiving groove for accommodating the first connector is provided on the first support surface, and a counter-pressure boss is provided on the third support surface, the pressing block and the second support surface are configured to clamp the straight part of the cable, and the pressing block and the third support surface are configured to clamp the bent part of the cable, and when the pressing block is pressed against the third support surface, the counter-pressure boss extends into the counter-pressure groove.

[0009] Preferably, the pressure block is provided with a first pressure surface and a second pressure surface in sequence along the second direction, and along the first direction, the first pressure surface and the second pressure surface are sequentially close to the support block, and the counter-pressure groove is provided on the second pressure surface, and the first pressure surface and the second support surface are configured to clamp the straight part of the cable, and the second pressure surface and the third support surface are configured to clamp the bent part of the cable.

[0010] Preferably, a third pressure surface is further provided on the pressure block. Along the second direction, the third pressure surface is located on the side of the second pressure surface away from the first pressure surface. Along the first direction, the third pressure surface is located on the side of the first pressure surface away from the support block. When the pressure block and the third support surface clamp the bent part of the cable, the second connector is located on the side of the third pressure surface close to the support block.

[0011] Preferably, a connecting groove is further provided on the first supporting surface, and the connecting groove connects the accommodating groove and the second supporting surface.

[0012] Preferably, a locking hole communicating with the accommodating groove is provided on the side wall of the supporting block.

[0020] Beneficial effects of the present invention:

[0021] The driving device drives the pressure block and the support block to press against each other, so that the wiring assembly can be efficiently bent and pressure maintained. By setting the first support surface and setting the accommodating groove on the first support surface, the first connector at one end of the wiring assembly can be positioned and fixed to avoid displacement during subsequent bending and pressure maintaining operations. The first support surface, the second support surface and the third support surface are gradually lowered relative to the pressure block, which is suitable for the cable and the second connector connected to the first connector in sequence. The pressure block and the second support surface can clamp the straight part of the cable to avoid warping of the straight part when operating on the bent part of the cable. When the pressure block and the third support surface clamp the bent part of the cable, the counter-pressure boss and the counter-pressure groove cooperate to clamp the bent part of the cable more tightly, with stronger force and larger effective area, which can effectively reduce the risk of rebound of the cable after bending.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figures 1-6 As shown, the wiring assembly includes a cable 100, a first connector 200 and a second connector 300. The first connector 200 and the second connector 300 are respectively arranged at both ends of the cable 100 and are connected by cables. The present invention provides a pressure-maintaining fixture for bending and maintaining pressure on the wiring assembly, including a driving device 1, a pressure block 2 and a support block 3. Among them, the pressure block 2 is arranged at the output end of the driving device 1, and the driving device 1 can drive the pressure block 2 to move along the first direction. A back-pressure groove 221 is provided on the pressure block 2, and a first supporting surface 31, a second supporting surface 32 and a third supporting surface 33 are provided on the support block 3 in sequence along the second direction. The second direction is perpendicular to the first direction. Along the first direction, the first supporting surface 31, the second supporting surface 32 and the third supporting surface 33 are successively away from the pressure block 2, and a receiving groove 311 for accommodating the first connector 200 is provided on the first supporting surface 31, and a back-pressure boss 331 is provided on the third supporting surface 33. The pressure block 2 and the second supporting surface 32 are configured to clamp the straight part of the cable 100, and the pressure block 2 and the third supporting surface 33 are configured to clamp the bent part of the cable 100. When the pressure block 2 is pressed on the third supporting surface 33, the back-pressure boss 331 extends into the back-pressure groove 221.

[0039] In the present invention, the driving device 1 drives the pressing block 2 and the supporting block 3 to abut against each other, so that the wiring assembly can be bent and pressure maintained efficiently. By providing the first supporting surface 31 and providing the accommodating groove 311 on the first supporting surface 31, the first connector 200 at one end of the wiring assembly can be positioned and fixed to avoid displacement during subsequent bending and pressure maintenance operations. The first supporting surface 31, the second supporting surface 32 and the third supporting surface 33 are gradually lowered relative to the pressing block 2, which is suitable for wiring connected to the first connector 200 in sequence. The cable 100 and the second connector 300, the pressing block 2 and the second supporting surface 32 can clamp the straight part of the cable 100 to prevent the straight part from warping when operating on the bent part of the cable 100. When the pressing block 2 and the third supporting surface 33 clamp the bent part of the cable 100, the counter-pressure protrusion 331 and the counter-pressure groove 221 cooperate with each other to clamp the bent part of the cable 100 more tightly, with stronger force and larger effective area, which can effectively reduce the risk of the cable 100 rebounding after bending.

[0040] Specifically, the counter-pressure projection 331 has a convex corrugated structure extending along a third direction, with a triangular cross-section. The third direction is perpendicular to the first and second directions. The counter-pressure groove 221 matches the shape of the counter-pressure projection 331. The top of the counter-pressure projection 331 does not protrude beyond the second support surface 32, but rather is positioned below the second support surface 32. In addition to the above configuration, the counter-pressure projection 331 can also have a convex corrugated structure with other cross-sectional shapes to achieve cable counter-pressure, which will not be described in detail here.

[0041] In this embodiment, the driving device 1 is a pneumatic device such as a cylinder, which can achieve pressure maintenance.

[0042] Specifically, the pressing block 2 is provided with a first pressing surface 21 and a second pressing surface 22 in sequence along the second direction. Along the first direction, the first pressing surface 21 and the second pressing surface 22 are sequentially close to the supporting block 3. The counter-pressure groove 221 is provided on the second pressing surface 22. The first pressing surface 21 and the second supporting surface 32 are configured to clamp the straight portion of the cable 100, and the second pressing surface 22 and the third supporting surface 33 are configured to clamp the bent portion of the cable 100. By providing the first pressing surface 21 and the second pressing surface 22, the straight portion and the bent portion of the cable 100 can be more accurately aligned and pressurized.

[0043] More specifically, the pressing block 2 is further provided with a third pressing surface 23. Along the second direction, the third pressing surface 23 is located on the side of the second pressing surface 22 facing away from the first pressing surface 21. Along the first direction, the third pressing surface 23 is located on the side of the first pressing surface 21 facing away from the support block 3. When the pressing block 2 and the third supporting surface 33 clamp the bent portion of the cable 100, the second connector 300 is located on the side of the third pressing surface 23 closer to the support block 3. The provision of the third pressing surface 23 protects the second connector 300 and prevents it from being pulled by the pressing block 2 during bending and pressure-maintaining.

[0044] In this embodiment, if Figure 4 As shown, two triangular ridges are formed on both sides of the counter-pressure groove 221 . Of the two triangular ridges, the height dimension of the triangular ridge close to the first pressing surface 21 is smaller than the height dimension of the triangular ridge far from the first pressing surface 21 .

[0045] Specifically, a connecting groove 312 is further provided on the first supporting surface 31, and the connecting groove 312 connects the receiving groove 311 and the second supporting surface 32. By providing the connecting groove 312, the cable 100 can be extended more smoothly from the receiving groove 311 to the second supporting surface 32.

[0046] In this embodiment, the bottom of the communicating groove 312 is flush with the second supporting surface 32 , thereby making the placement of the straight portion of the cable more reliable.

[0047] More specifically, a locking hole 34 is provided on the side wall of the support block 3 and is connected to the receiving groove 311. When the first connector 200 is placed in the receiving groove 311, a fastener is assembled in the locking hole 34 so that the fastener abuts against the first connector 200, thereby locking the first connector 200.

[0048] In this embodiment, two locking holes 34 are arranged side by side, and the fasteners are bolts threaded into the locking holes 34 , which can more reliably lock the first connector 200 .

[0049] Specifically, the driving devices 1 correspond to the supporting blocks 3 one by one, and a plurality of the driving devices 1 are respectively provided, so that a plurality of wiring assemblies can be bent and pressurized at the same time.

[0050] In this embodiment, three driving devices 1 and three supporting blocks 3 are provided respectively. The three driving devices 1 are parallel to each other and are sequentially spaced apart along the second direction.

[0051] Specifically, the pressure-maintaining fixture further includes a base 4, on which the driving device 1 and the support block 3 are respectively disposed. By providing the base 4, the driving device 1, the pressure block 2, and the support block 3 can be more reliably supported and carried, facilitating the transportation and use of the entire pressure-maintaining fixture.

[0052] More specifically, the base 4 includes a bottom support 41 and a vertical plate 42. The support block 3 and the vertical plate 42 are respectively arranged on the bottom support 41. The drive device 1 is arranged on the vertical plate 42 and is located above the support block 3. The overall arrangement is more compact and reasonable.

[0053] In this embodiment, the bottom support 41 is a box structure, which is assembled from a plurality of plates.

[0054] Specifically, the base 4 further includes a panel 43 connected to the upright 42. The panel 43 and the upright 42 enclose a working space, and the output end of the drive device 1 is located in the working space. The provision of the panel 43 can protect the bending and pressure-maintaining process and prevent foreign matter from interfering with the output end of the drive device 1.

[0055] More specifically, at least a portion of the enclosure 43 is made of a transparent material, thereby facilitating an operator to observe the operating status of the output end of the drive device 1 .

[0056] In this embodiment, the enclosure 43 includes two side baffles 431 and a front baffle 432. The two side baffles 431 are respectively connected to the two ends of the vertical plate 42 along the second direction. The front baffle 432 is arranged parallel to the vertical plate 42, and its two ends are respectively connected to the two side baffles 431. The front baffle 432 is a transparent acrylic plate, which is convenient for the operator to observe from the outside of the working space.

[0057] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
