At present, most wire harness manufacturers use crimping machines to automatically complete the crimping process, but the process of feeding the wire into the crimping position corresponding to the terminal housing 14 still relies mainly on manual work, and the control of the wire reaching the crimping position corresponding to the terminal housing 14 directly affects the quality of the wire harness terminal; manual work is affected by the proficiency of the operator and is also restricted by the operator's state, which is not conducive to the control of product quality. Utility Model Content

[0003] The utility model aims to provide a wire harness terminal crimping device, which has the advantage of being convenient for controlling product quality.

[0004] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides the following technical solutions: a wire harness terminal crimping device, comprising:

[0005] A terminal support body for carrying the terminal;

[0006] a guide member, located above the terminal support body and having a guide channel for the power supply line to penetrate in an axial direction parallel to the wiring slot of the terminal; and

[0007] The clamping assembly provides a clamping force to the electric wire in the guide channel so that the electric wire is clamped into the wiring slot of the terminal.

[0008] Through the above technical solution, when performing the crimping work, the operator inserts the end of the wire into the guide channel opened on the guide member, and then the clamping assembly applies a squeezing force to the wire, so that the wire located in the guide channel passes through the guide channel into the wiring groove. The guide channel guides the wire. The wire will not deviate when passing through the guide channel, and thus enters the wiring groove in a linear direction, thereby guiding the operator to complete the assembly of the wire and the terminal. The operator's proficiency and state are little affected, which facilitates the control of product quality.

[0009] In one embodiment of the utility model, it further includes a sliding support body for the terminal support body to slide, and a sliding drive member, wherein the sliding drive member drives the terminal support body to slide and makes it stay at a preset position below the guide member.

[0010] Through the above technical solution, when the sliding drive member drives the terminal support body to reach the preset position under the guide member, the wires and the terminals are compressed and assembled. After completing the process of pressing the wires into the terminal wiring grooves, the sliding drive member drives the terminal support body to continue moving to remove the finished wire harness and install the terminals to be processed.

[0011] In one embodiment of the present invention, the guide channel includes a wire lead hole for guiding the wire to pass through, and a guide groove communicating with the wire lead hole.

[0012] Through the above technical solution, since the size of the wires is generally small, the guide channel will also be designed to have the same width accordingly. When the operator inserts the wires, there will be a problem of alignment, which increases the operator's workload to a certain extent. The lead-in hole can lead the wires into the guide channel to avoid alignment problems.

[0013] In an embodiment of the present invention, the diameter of the lead hole decreases toward the inside of the guide member.

[0014] Through the above technical solution, the lead-in hole can use its taper to lead the wire into the wire insertion hole, making it convenient for operators to insert the wire.

[0015] In an embodiment of the present invention, the lead hole is conical.

[0016] Through the above technical solution, the conical lead-in hole can use its taper to lead the wire into the wire insertion hole, making it convenient for operators to insert the wire.

[0017] In one embodiment of the present invention, the clamping assembly includes a clamping block and a clamping driving member for applying a clamping force on the clamping block in the same direction as the length direction of the guide channel.

[0018] Through the above technical solution, the crimping drive member applies force to the crimping block, and the crimping block directly contacts the wire to act on the wire, thereby crimping and assembling the wire and the terminal.

[0019] As described above, the wire harness terminal crimping device of the utility model has the following beneficial effects:

[0020] When performing the crimping work, the operator inserts the end of the wire into the guide channel opened on the guide piece, and then the clamping assembly applies a squeezing force to the wire, so that the wire in the guide channel passes through the guide channel into the wiring groove. The guide channel guides the wire, and the wire will not deviate when passing through the guide channel, so it enters the wiring groove in a linear direction, thereby guiding the operator to complete the assembly of the wire and the terminal. It is little affected by the operator's proficiency and status, which facilitates the control of product quality. BRIEF DESCRIPTION OF THE DRAWINGS
