Description

Variable jig for harness cable assembly {VARIABLE JIG FOR ASSEMBLING HARNESS CABLE}

The present invention relates to a harness cable assembly jig used to assemble a harness cable (wiring) that is mounted vertically on a workbench and conducts electricity in a vehicle or various electrical devices, and more specifically, various types manufactured in different standards. As the height and width of the part where the harness cable is supported is variable in response to the type of harness cable, a single product stably supports the harness cable regardless of the size (volume) of various types of harness cables and assembles various types of harness cables. It relates to a variable jig for harness cable assembly that can improve performance and secure economic feasibility by lowering assembly cost.

In recent years, as interest in environmental pollution has increased worldwide, interest in eco-friendly vehicles has increased, and the supply of electric vehicles or hybrid vehicles is rapidly increasing. As a result, the importance of a harness responsible for power supply or signal communication of a vehicle is increasing day by day in terms of vehicle performance or convenience.

These harnesses are important enough to be likened to human nerves or blood vessels in automobiles. In order to operate automatic control panels not only in the automotive technology field but also in the industrial field and automated mechanical facilities, the automatic control panel, PLC program, and control servomotor , it is essential to electrically connect hydraulic or pneumatic equipment.

1 is a view showing an example for explaining a general harness cable fixing jig, and FIG. 2 is a view showing a usage example of the harness cable fixing jig shown in FIG.

1 and 2, a general harness cable fixing jig 1 includes a 'U'-shaped head 2 for seating a harness cable or fixing a connector connected to an end of the harness cable, and a head 2 ) and consists of a pole (4) with a screw thread (5) formed at the end.

In addition, the pole 4 has a screw thread 5 formed at the bottom, and an installation hole 7 is formed in the work table (panel) 3. In the pole 4, a part of the lower part where the screw thread 5 is formed penetrates the installation hole 7 and protrudes downward, and the screw thread 5 of the pole 4 protrudes downward of the work table 3 has a nut 6 ) is screwed and fastened to the work table (3). Accordingly, the harness cable fixing jig 1 is mounted and fixed in a vertically erected state with respect to the work table 3 .

However, since the general harness cable fixing jig 1 has a structure in which the head 2 is fixed in a 'U' shape, different sizes are manufactured according to the size of the harness cable to be assembled, as shown in FIG. 2. Since the plurality of harness cable fixing jigs 1 must be mounted on a workbench and used, there is a problem in that workability and productivity deteriorate.

That is, when the vehicle type is changed, the unilateral harness cable needs to be newly manufactured as the width and length are changed according to the specifications of the changed vehicle model. Conventionally, the length has been measured and manufactured manually while looking at the design drawing. However, as vehicle types gradually diversify, manual production of harness cables has limitations. Accordingly, there has been a demand for a variable jig capable of widely applying harness cables having various standards.

In order to solve this problem, Korean Utility Model Registration No. 20-0486056 includes a variable mounting member that changes the width of the head on which the harness cable is mounted by combining additional connecting members in response to the specifications of the harness cable (wire harness). A variable jig is proposed.

However, in Korean Utility Model Registration No. 20-0486056, since the variable width is determined by the length of the connecting member, a large number of connecting members (tubular structures) must be additionally manufactured and assembled in response to various specifications of the harness cable. Therefore, the workability is deteriorated and the manufacturing cost is increased. In addition, although the width can be varied to correspond to various specifications of the harness cable, the height cannot be adjusted, so when the amount of harness cable accommodated in the head increases, there is a problem in that the harness cable is separated from the head.

In addition, Korean Patent Registration No. 10-1159698 discloses a harness cable, that is, a head in which a wire harness is accommodated at the top in a 'U' shape so that the head height can be adjusted to suit the amount of wire, and to maintain the head at a predetermined height. A harness jig including a body formed perpendicular to the lower part of the head and fixed to a panel, and a variable head that is fastened to surround the outer surface of the head and moves up and down along the outer surface of the head has been proposed.

In the technology proposed in Korean Patent Registration No. 10-1159698, the height of the head can be adjusted by combining the variable head with the head. Since it has to be assembled to the back head, the workability is reduced due to the complexity of the work, and the manufacturing cost also increases.

In addition, when the width-variable jig proposed in Korean Utility Model Registration No. 20-0486056 and the height-variable jig proposed in Korean Patent Registration No. 10-1159698 are combined, the width and height cannot be adjusted respectively in response to the harness cable. However, as the width and height are adjusted by combining the connecting member and the variable head, the width and height are determined by the length of the connecting member and the variable head, so the adjustment range of the width and height is limited.

That is, in the variable jig proposed in Korean Utility Model Registration No. 20-0486056 and Korean Patent Registration No. 10-1159698, the width and height of the head are determined by the length of the connecting member and the variable head, respectively. It is virtually difficult to satisfy all harness cables having various standards due to size limitations with one connecting member and a variable head.

Of course, it is possible to increase the adjustment range of the width and height by making the length of the connecting member and the variable head of the conventional variable jig as long as possible, but in this case, unnecessary waste occurs, and when a plurality of variable jigs are installed on the same workbench, they are mutually exclusive. During the assembly work of harness cables of different standards, interference may cause deterioration of workability.

In addition, through the connecting member proposed in Korean Utility Model Registration No. 20-0486056 and the variable head proposed in Korean Patent Registration No. 10-1159698, the width and height can be adjusted in response to harness cables having various standards, that is, various sizes. The work can be complicated because it cannot be adjusted at uniform intervals, and the width and height must be adjusted through disassembly and assembly processes.

In addition, the connection member proposed in Korean Utility Model Registration No. 20-0486056 is coupled between the head and the variable mounting member through a fastening protrusion, and the variable head proposed in Korean Patent Registration No. 10-1159698 is connected to the head through a fixing pin. There is a limit to maximizing the bonding force as it is made of a structure that is coupled to and fixed to, that is, a structure in which one point is mutually coupled and assembled by a fastening protrusion or a fixing pin. As a result, when a strong tension is applied to the harness cable, the variable jig mounted on the worktable at the point where the harness cable is bent may have a problem in that the connecting member and the variable head cannot withstand the tension applied to the harness cable and tilt to one side.

In addition, the connection member proposed in Korean Utility Model Registration No. 20-0486056 is coupled between the head and the variable mounting member through a fastening protrusion, and the variable head proposed in Korean Patent Registration No. 10-1159698 is connected to the head through a fixing pin. As they are fixed to, their combining work is cumbersome and complicated. In particular, in Korean Patent Registration No. 10-1159698, as the fixing pins are aligned and fixed to the variable head and the fixing groove formed in the head, the work may be cumbersome and inconvenient.
