Description

Technical Field

[0001] This application relates to the field of wire harness terminal technology, and in particular to a wire harness terminal box that allows for quick wiring. Background Technology

[0002] Quick-connection wire harness terminal boxes are devices used for quick connection and branching of cables, and are widely used in power, electronics, automotive and other fields.

[0003] In the existing technology, external tools such as screwdrivers, wire strippers, and crimping pliers are usually required during the installation of terminal blocks; for example, when installing wires, wire strippers and wire pliers are required to strip and crimp the wires.

[0004] Regarding the aforementioned technologies, the inventors believe that using external tools to strip the wires before connecting them increases the complexity of the operation and may also reduce work efficiency due to the lack or unsuitability of the tools. Utility Model Content

[0005] The purpose of this application is to provide a wire harness terminal box that allows for quick wiring, thereby improving the problem that the process of stripping wires with external tools before connecting them increases operational complexity and may reduce work efficiency due to the lack or unsuitability of tools.

[0006] This application provides a wire harness terminal box for quick wiring, which adopts the following technical solution:

[0007] A wire harness terminal box for quick wiring includes a box body, the box body including a fixing block and a locking block disposed on one side of the fixing block, the locking block having a through groove in the vertical direction, a terminal head disposed in the through groove, a pair of clamping plates for holding wires disposed on the bottom surface of the terminal head, and a pair of cutting blades for cutting the wire insulation of the terminal head.

[0008] By adopting the above technical solution, the cutting blade cuts through the guide rubber when the wire is installed into the terminal head, thereby making electrical connection with the terminal head. The clamping plate holds and connects other wires, realizing the connection of the wires. There is no need to strip the wires with external tools first, which solves the problem of reduced work efficiency due to the lack of tools or unsuitable tools.

[0009] Optionally, the side wall of the through groove is provided with a locking groove, and the terminal head is provided with a locking plate that slides and engages with the locking groove. The locking plate has a fixing groove for engaging and fixing the wire.

[0010] By adopting the above technical solution, the terminal head can be quickly installed by setting a locking plate and engaging the locking groove on the side wall of the through groove, thereby improving installation efficiency; at the same time, the through groove has a guiding and limiting effect on the locking plate, so that the terminal head is stably fixed in the through groove.

[0011] Optionally, the width of the fixing groove at its bottom is greater than the width of its opening.

[0012] By adopting the above technical solution and setting a teardrop-shaped fixing groove, the wire is locked and fixed after being pressed and installed into the fixing groove, which restricts the wire's movement in the vertical direction in the terminal head and prevents the wire from popping out of the fixing groove; this facilitates the pressing and installation of the wire and improves the installation efficiency of the wire.

[0013] Optionally, the fixing block is provided with an elastic fastener on the side wall of the through groove, the fixing block is provided with an installation groove, and the elastic fastener is provided on the top surface of the side wall of the installation groove to prevent the wire in the installation groove from leaving the installation groove in the vertical direction.

[0014] By adopting the above technical solution, and by setting up elastic fasteners, the wire is pressed into the installation groove, preventing the wire in the installation groove from leaving the installation groove in the vertical direction; in conjunction with the locking plate, the wire is locked and fixed at two points, which is conducive to the horizontal placement of the wire and improves the stability of the wire fixation.

[0015] Optionally, the locking block is provided with an external groove communicating with the through groove along the mounting groove direction.

[0016] By adopting the above technical solution, the wiring direction of the wires is expanded by setting an external slot. The wires perpendicular to the wires in the terminal head can be connected in the fixed slot. The wires horizontal to the wires in the terminal head are inserted through the external slot, and the power is transmitted by clamping the clamping plate. This avoids bending the wires during connection, which affects the service life of the wires, and at the same time, the terminal clamping plate can clamp and connect more wires.

[0017] Optionally, the clamping plate has an arc-shaped surface at one end near the external slot to facilitate the insertion of external wires into the clamping plate.

[0018] By adopting the above technical solution, the arc-shaped surface facilitates the installation of wires in the external slot. The wires are squeezed against the arc-shaped surface and are more easily and effortlessly clamped and fixed by the clamping plate, thus improving wiring efficiency.

[0019] Optionally, the fixing block is provided with a threaded hole, and a mounting screw is provided in the threaded hole.

[0020] By adopting the above technical solution and setting mounting screws, in some working environments where the box needs to be fixed, it is easier to fix the box and make wiring stable. After fixing the box, it is easier to make wiring operations.

[0021] Optionally, the locking block is at a higher horizontal height than the fixing block, meaning that after the fixing block is fixedly installed on the mounting surface, the locking plate does not contact the mounting surface.

[0022] By adopting the above technical solution, the lower surface of the locking block is made to be at a higher horizontal level than the lower surface of the fixing block.

[0023] In summary, this application includes at least one of the following beneficial technical effects of a wire harness terminal box that enables quick wiring:

[0024] 1. By setting a cutting blade, when the wire is installed into the terminal head, the cutting blade cuts through the outer rubber of the guide, thereby making electrical connection with the terminal head. By setting a clamping plate to hold and connect other wires, the wire connection is realized without the need to strip the wires with external tools first, thus solving the problem of reduced work efficiency due to the lack of tools or unsuitable tools.

[0025] 2. By setting up elastic fasteners, the wire is pressed into the mounting groove, preventing the wire in the mounting groove from leaving the mounting groove in the vertical direction; in conjunction with the locking plate, the wire is locked and fixed at two points, which facilitates the horizontal placement of the wire and improves the stability of the wire fixation.

[0026] Optionally, the engaging block is provided with an external groove communicating with the through groove along the mounting groove direction;

[0027] 3. By setting external slots to expand the wiring direction of wires, wires perpendicular to the wire direction in the terminal head can be connected in the fixed slot, and wires horizontal to the wire direction in the terminal head can be inserted through the external slots. Power is transmitted by clamping the clamping plate; this avoids bending of wires during connection, which affects the service life of the wires, and at the same time allows the terminal clamping plate to clamp and connect more wires.

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0033] Reference Figure 1 , Figure 2 A wire harness terminal box for quick wiring, see reference. Figure 1 The box includes a housing 1, which is made entirely of insulating material. The housing 1 includes a fixing block 11 and a locking block 12 disposed on one side of the fixing block 11. The fixing block 11 and the locking block 12 are integrally formed. The fixing block 11 is provided with a threaded hole 13, and a mounting screw 14 is provided in the threaded hole 13. The lower surface of the locking block 12 is higher than the lower surface of the fixing block 11 at a horizontal height. That is, after the fixing block 11 is fixedly installed on the mounting plane by the mounting screw 14, the locking plate 7 does not contact the mounting plane. The locking block 12 is provided with a through groove 2 in the vertical direction. There is a baffle at the lower opening of the through groove 2. The baffle is the structure of the locking block 12 itself.

[0034] The locking plate 7 has a fixing groove 71 for locking and fixing the wire. The width of the fixing groove 71 at the bottom is greater than the width of the groove opening, that is, it is narrower at the top and wider at the bottom. The bottom surface of the terminal head 3 is provided with a pair of clamping plates 4 for clamping the wire. The clamping plates 4 are integrally set with the terminal head 3. One end of the clamping plate 4 is provided with an arc-shaped surface 41 to facilitate the insertion of external wires into the clamping plate 4. The locking block 12 is provided with an external groove 10 that communicates with the through groove 2 along the direction of the mounting groove 9.

[0035] Reference Figure 2 , Figure 3 The through groove 2 has a locking groove 6 on its side wall, and a terminal head 3 is installed inside the through groove 2. The terminal head 3 is a metal conductive structure. The terminal head 3 is provided with a locking plate 7 that slides and engages with the locking groove 6. The terminal head 3 is fixed in the through groove 2 by the engagement of the locking plate 7 and the locking groove 6. The baffle prevents the terminal head 3 from moving down and avoids the terminal head 3 from moving out of the bottom surface of the through groove 2. The terminal head 3 is integrally provided with a pair of cutting blades 5 that can cut the wire insulation. When the wire is installed, the cutting blades 5 cut the outer insulation of the wire, so that the internal conductive structure of the wire is electrically connected to the terminal head 3.

[0036] The implementation principle of this application embodiment is as follows:

[0037] In actual use, the terminal head 3 is fixed in the through slot 2 by the snap-fit ​​plate 7, and the conductive part of a section of the wire to be connected is clamped and fixed by the clamping plate 4. The other section of the wire to be connected is placed on the box 1 and aligned with the mounting slot 9 and the fixing slot 71. The section of the wire to be connected is manually pressed down horizontally. As the section of the wire is pressed down, it is fixed in the mounting slot 9 and the fixing slot 71. At the same time, the cutting blade 5 cuts its outer rubber as the section of the wire is pressed down, so that its internal conductive structure is connected to the terminal head 3. The wire to be connected is connected through the terminal head 3. The wire held by the clamping plate 4 is conductive. The installation process does not require the use of external tools to strip the wire first, which solves the problem of reduced work efficiency due to the lack of tools or unsuitable tools.
