Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness measurement devices, and particularly relates to a multi-terminal cable wire harness length measurement device. Background Art

[0002] A wire is a basic component that physically connects two electrical components to achieve electrical connection between the two electrical components. With the development of large-scale integrated circuits, the structures of various electrical equipment are becoming increasingly complex. Some electrical equipment often requires a large number of wires. In order to arrange the cable wires neatly inside the electrical equipment, the wires with the same wiring direction are concentrated together and called a wire harness. In the existing cable wire harness, multiple electrical connector terminals can be connected at both ends, that is, it is called a multi-terminal cable wire harness. During the production process of the cable wire harness, the length accuracy of the wire during cutting has an important impact on whether the product can meet the requirements of customers and subsequent processing requirements. At present, common cable wire harness measurement tools mainly include a tape measure, a steel straight ruler, etc. However, due to the flexibility of the cable wire harness, when the wires in the cable wire harness are in a bent state, measurement tools such as a tape measure and a steel straight ruler often cannot accurately measure it.

[0003] In the prior art, a patent document with the publication number of "CN207019586U" discloses a wire harness length measuring instrument, which is characterized in that it includes: a base: a slide rail, a wire groove and a linear scale are arranged on the base, and a wire is placed in the wire groove; a clamp: arranged at one end of the base for locking the end of the wire; a reading head: arranged on the base, the reading head can slide left and right along the slide rail through a groove arranged at the bottom, and a convex block is further arranged at the bottom of the reading head, the convex block is attached to the surface of the wire groove, and the reading head is connected to an external display. Adopting the technical solution of this patent can improve the length measurement accuracy of the cable wire harness to a certain extent. However, for a multi-terminal cable wire harness, it is impossible to separately measure the lengths of the cable wire harnesses at each terminal. Summary of the Utility Model

The length direction of the guide groove is parallel or perpendicular to the length direction of the constraint wire groove. The slider is accommodated in the mother accommodating groove. A limit groove and a clamping groove are further arranged on the surface of the slider. The guide block is sleeved in the guide groove. The dial rod is screwed to the guide block, and one end of the dial rod is sleeved in the clamping groove, and the other end of the dial rod extends beyond the bottom plate.

[0006] A support seat is further arranged in the mother accommodating groove. A son accommodating groove is arranged on the surface of the support seat. The guide groove is also arranged on the surface of the support seat. The slider is also sleeved in the son accommodating groove.

Multiple scale lines are also provided on the surfaces of the base plate 1 and the lever 2, and the scale lines are arranged at equal intervals along the length direction of the constraint wire groove 5 or the lever 2 respectively. The constraint wire groove 5 is also communicated with the reference groove 6. Among them, the scale line flush with the bottom of the reference groove 6 is used as the zero baseline. The length direction of the guide groove 8 is parallel or perpendicular to the length direction of the constraint wire groove 5. The slider 4 is accommodated in the receiving mother groove 7. The surface of the slider 4 is also provided with a limiting groove 9 and a clamping groove 10. The guide block 3 is sleeved in the guide groove 8. The lever 2 is screwed to the guide block 3, and one end of the lever 2 is sleeved in the clamping groove 10, and the other end of the lever 2 extends outside the base plate 1.

[0025] Adopting the technical solution provided by the present utility model, when the cable harness is placed in the constraint wire groove and the main bus connector at one end of the cable harness is sleeved in the reference groove, at this time, the scale line flush with the bottom of the reference groove 6 is used as the zero baseline. Then, the multiple end connectors at the other end of the cable harness are respectively sleeved in the respective limiting grooves. The operator applies a rotational torque to the lever, so that the slider moves along the corresponding length direction of the lever, thereby straightening the end wire harnesses of the cable harness along at least two directions, laying a foundation for improving the length measurement accuracy. In addition, scale lines are provided on the surfaces of both the base plate and the lever. The operator can directly read the readings from the scale lines on the surfaces of the base plate and the lever with the naked eye, and quickly and accurately obtain the lengths of the end wire harnesses of each branch of the cable harness. Compared with the prior art, the present utility model has the advantages of simple structure, convenient operation and low manufacturing cost.
