Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring harness manufacturing equipment, in particular to a connector clamping device and an automobile wiring harness assembly and testing device. Background Art

[0002] A wiring harness is a component that is made of copper material, and then the contact terminal (connector) is crimped with the wire cable, and then the insulator is plastic-pressed or metal shell is added to the outside to bundle multiple wires to form a connecting circuit. In the automotive electrical system, the wiring harness is the main network of the automotive electrical system, connecting the electrical and electronic components of the car and making them function. Without the wiring harness, there would be no automotive circuit.

[0003] With the increasing demand for automobile functions and the widespread application of electronic control technology, more and more electrical parts are being added, and the number of circuits and power consumption in automobiles has increased significantly. The number of wires in the wiring harness will also increase, and the wiring harness will become thicker and heavier, the production cost will also increase, and the failure rate will also increase accordingly, so the wiring harness assembly process must be refined to ensure product quality and reduce production costs. Therefore, how to arrange a large number of wiring harnesses more effectively and reasonably in the limited space of the car so that the automobile wiring harness can play a greater role has become a problem facing the automobile manufacturing industry.

[0004] At present, wiring harness manufacturers have put forward higher and higher requirements for the production quality of automotive wiring harnesses. However, for automotive wiring harnesses with many types of raw materials and various messy and diverse processes, manufacturers do not have a better way of operation. Most of them can only control each process once in the traditional way, which leads to low production efficiency. Therefore, it is necessary to design a multifunctional operating device to combine multiple processes of automotive wiring harnesses as much as possible, so that the same operator can complete multiple processes on the same device to improve production efficiency. Utility Model Content

[0005] The purpose of the utility model is a connector clamping device and an automobile wiring harness assembly and testing device, which combines the automobile wiring harness detection and bundling processes and implements them on an operating device, which can not only detect the length of each wire in the wiring harness, but also improve the production quality and production efficiency of the automobile wiring harness, and has strong versatility, and the parts on the adjustment device can be suitable for the production of different products.

[0006] In order to achieve the above technical purpose, the technical solution of the utility model is:

[0007] The automobile wiring harness assembly test device comprises a plurality of groups (not less than one group) of wire end positioning blocks and a plurality of (not less than one) tie band positioning blocks, wherein the wire end positioning blocks comprise a first wire end positioning block and a second wire end positioning block, wherein the tie band positioning block is provided with a wire positioning groove and a tie band bundling groove, wherein the wire positioning groove is used for positioning the wire, and the tie band bundling groove is used for bundling the wire with a tie band, wherein the wire end positioning blocks and the tie band positioning blocks are arranged according to the wiring harness structure, wherein the first wire end positioning block and the second wire end positioning block of each group of wire end positioning blocks are respectively used for positioning the two ends of a certain wire, and the length of a certain wire is detected through the path from the first wire end positioning block to the tie band positioning block to the second wire end positioning block.

[0008] The number and layout structure of the first wire end positioning block, the second wire end positioning block and the tie band positioning block on the bottom plate are distributed according to the wire harness structure, the wire bundling point and the wire length, and then the ends of the wires are connected to the first wire end positioning block and the second wire end positioning block in turn, and the wires are inserted into the wire positioning groove of the tie band positioning block. When a certain wire length in the wire harness is too long or too short, it is easy to be quickly detected. For example, when a certain wire length in the wire harness is too short, when the wire is inserted into the wire positioning groove and one end of it is connected to the first wire end positioning block, the other end of the wire cannot be connected to the corresponding second wire end positioning block; for another example, when a certain wire length in the wire harness is too long, when the wire is inserted into the wire positioning groove and one end of it is connected to the first wire end positioning block, the other end of the wire will exceed the position of the corresponding second wire end positioning block, thereby realizing the rapid detection of the wire length, so as to detect whether the length of each wire in the wire harness meets the size requirements, and there is no need to measure the length again during the full inspection in the later process, thereby reducing the production process and improving product quality and production efficiency.

[0009] When the wire harness is connected to the tie band positioning block, the wire positioning groove of the tie band positioning block can position and guide the wire. The tie band bundling groove on the tie band positioning block can not only locate the bundling point of the tie band bundling wire, but also allow the tie band to pass between the wire harness and the tie band positioning block to achieve the bundling of the wire, ensure the bundling position of each wire harness is the same, ensure that the wire harness meets the standard requirements, and improve product quality. For example, the tie band is inserted between the wire and the tie band positioning block through one side of the tie band bundling groove and led out from the other side of the tie band bundling groove to achieve the positioning and bundling of the wire, improving product quality and bundling efficiency.

[0010] It should be noted that if a certain group of wire end positioning blocks is used to locate the length of a certain wire in the detection harness, the number of wire end positioning blocks should be set according to the number of wires in the harness in a 1:1 matching manner, and the first wire end positioning block and the second wire end positioning block are used to locate the two ends of a certain wire in the harness, then the number of the first wire end positioning blocks and the number of the second wire end positioning blocks should also be set according to the number of wires in the harness in a 1:1 matching manner (the sum of the number of the first wire end positioning blocks and the second wire end positioning blocks is twice the number of wires in the harness), but the multiple groups of the above multiple groups of wire end positioning blocks are functional descriptions, and do not represent the number of entities of the wire end positioning blocks. In actual use, the same wire end positioning block can simultaneously locate the ends of multiple wires, so as to realize the function of detecting the length of the wires in the harness. For example, the end positioning functions of multiple wires can be combined on the same physical end positioning block, so as to realize the function that the same physical end positioning block can simultaneously locate the ends of multiple wires. Similarly, the first wire end positioning block and the second wire end positioning block are only functional descriptions that reflect the distinction and positioning of the two ends of a certain wire, so as to realize the wire end positioning function, and do not specifically refer to a physical end positioning block. For example, the second wire end positioning block for positioning a certain wire may also be the first wire end positioning block for another wire.

[0011] The tie belt positioning block is a three-hole tie belt positioning block or a two-hole tie belt positioning block. The wire positioning slot of the three-hole tie belt positioning block is provided with three wire inlets and outlets, and the wire positioning slot of the two-hole tie belt positioning block is provided with two wire inlets and outlets. The three-hole tie belt positioning block is provided with two tie belt bundling slots.

[0012] The wire end positioning blocks are all provided with test leads, which are used to connect the wires. By measuring the test leads at both ends of the same wire in the harness, it is possible to detect whether the wires are conductive and whether the contact resistance of the wires is within the standard range.

[0013] The physical structures of the first wire end positioning block and the second wire end positioning block can be provided with wire end positioning blocks of different structures according to the conditions of the wire ends.

[0014] For example, the wire end positioning block may be provided with a connector clamping device, which is used to clamp the connector at the wire end. The connector clamping device can be used to quickly clamp the connector, thereby reducing the difficulty of operation and improving work efficiency.

[0015] The connector clamping device is provided with a plug-in, which is used to plug the connector at the end of the wire, and the copper terminal of the plug-in is connected to the copper terminal of the connector, and the copper terminal of the plug-in is connected to the test lead.

[0016] The connector clamping device includes a connector tail end stop block, the connector tail end stop block is cooperated with a stop block avoidance groove, the connector tail end stop block slides back and forth along the stop block avoidance groove, a return spring is arranged between the connector tail end stop block and the stop block avoidance groove, after the connector tail end stop block slides and avoids along the stop block avoidance groove, the return spring is used to reset the connector tail end stop block to the tail end of the connector.

[0017] The connector tail end stop block is provided with an extrusion slope, and the extrusion slope is used to push the connector tail end stop block to slide along the stop block avoidance slide groove.

[0018] In order to guide the sliding direction of the connector tail end stop block and limit the connector tail end stop block to prevent the connector tail end stop block from escaping from the stop block avoidance groove, the connector tail end stop block is provided with a guide rod, and the stop block avoidance groove is provided with a guide bar hole. When the connector tail end stop block slides along the stop block avoidance groove, the guide rod slides in the guide bar hole.

[0019] When in use, the connector at the end of the wire is inserted into the plug-in unit in parallel from the side of the stop block at the rear end of the connector. During this process, the connector at the end of the wire pushes the extrusion slope of the stop block at the rear end of the connector, so that the stop block at the rear end of the connector slides along the stop block avoidance groove to avoid (the guide rod slides in the guide bar hole); after the extrusion slope is freed from the restraint of the connector, the reset spring is reset, so that the stop block at the rear end of the connector slides along the stop block avoidance groove to reset, so that the stop block at the rear end of the connector is blocked at the rear end of the connector.

[0020] The copper terminal of the plug-in is provided with an arc protrusion. When in use, the arc protrusion of the copper terminal of the plug-in can increase the contact area between the copper terminal of the plug-in and the copper terminal of the connector, so that the plug-in terminal and the connector terminal are in close contact. Through the arc transition, it can also be easily inserted and removed, reducing the fatigue of employees.

[0021] The wire end positioning block may be provided with a terminal detection groove, in which a terminal connecting column is provided, the terminal connecting column is used to detect the inner diameter of the O-type terminal at the wire end, and the terminal detection groove is used to detect the outer diameter of the O-type terminal at the wire end.

[0022] According to the model and size of the wire harness O-type terminal, set the terminal detection slot and terminal connection column of the same size. When in use, the terminal detection slot can detect the outer diameter of the wire O-type terminal, and the terminal connection column can detect the inner diameter of the wire O-type terminal. If the inner diameter of the O-type terminal is too large, there will be a gap between it and the terminal connection column after it is placed in the terminal detection slot; if the inner diameter of the O-type terminal is too small, it cannot be put on the terminal connection column; if the outer diameter of the O-type terminal is too large, it cannot be put into the terminal detection slot; if the outer diameter of the O-type terminal is too small, there will be a gap between it and the terminal detection slot after it is put on the terminal connection column; therefore, through the terminal detection slot and the terminal connection column, the size of the O-type terminal can be quickly detected to ensure product quality. At the same time, the setting of the terminal detection slot and the terminal connection column has a fool-proof effect and is easy for operators to operate.

[0023] The terminal connection column is connected to a test lead.

[0038] Between the left first wire end positioning block 41 and the right first wire end positioning block 42, a three-hole tie-wrap positioning block 2 is connected to the bottom plate 1 by screws, and the three-hole tie-wrap positioning block 2 is provided with a wire positioning groove, and the three-hole tie-wrap positioning block 2 is located at the above-mentioned intersection (the intersection of 11, 12, and 13), and the first wire 11, the second wire 12, and the third wire 13 are all inserted into the wire positioning groove of the three-hole tie-wrap positioning block 2. Specifically, the wire positioning groove of the three-hole tie band positioning block 2 is provided with a first three-hole wire inlet and outlet 21 and a second three-hole wire inlet and outlet 22. Between the first three-hole wire inlet and outlet 21 and the second three-hole wire inlet and outlet 22, the wire positioning groove of the three-hole tie band positioning block 2 is also provided with a third three-hole wire inlet and outlet 23.

[0039] A gap is left between the left second wire end positioning block 81 and the right second wire end positioning block 82 on the bottom plate 1 according to the above-mentioned wiring harness structure. A two-hole tie band positioning block 3 is connected to the bottom plate 1 by screws between the three-hole tie band positioning block 2 and the left second wire end positioning block 81 and the right second wire end positioning block 82. The two-hole tie band positioning block 3 is provided with a wire positioning groove. The wire positioning groove of the two-hole tie band positioning block 3 is provided with a first two-hole wire inlet and outlet 31 and a second two-hole wire inlet and outlet 32. The first two-hole wire inlet and outlet 31 and the second two-hole wire inlet and outlet 32 ​​are both connected to the wire positioning groove of the two-hole tie band positioning block 3. The second wire 12 and the third wire 13 are inserted into the wire positioning groove of the two-hole tie band positioning block 3.

[0040] The spacing between the left first wire end positioning block 41 through the three-hole tie band positioning block 2 and the right first wire end positioning block 42 is set according to the length of the first wire 11, the spacing between the left first wire end positioning block 41 through the three-hole tie band positioning block 2 and the two-hole tie band positioning block 3 and the left second wire end positioning block 81 is set according to the length of the second wire 12, and the spacing between the right first wire end positioning block 42 through the three-hole tie band positioning block 2 and the two-hole tie band positioning block 3 and the right second wire end positioning block 82 is set according to the length of the third wire 13.

[0041] After the connector 10 at the head end of the first wire 11 and the connector 10 at the head end of the second wire 12 are positioned by the left first wire end positioning block 41, the first wire 11 passes through the three-hole tie band positioning block 2 to the right first wire end positioning block 42. If the first wire 11 meets the length standard, the connector 10 at the tail end of the first wire 11 can be positioned by the right first wire end positioning block 42; if the first wire 11 is shorter, the connector 10 at the tail end of the first wire 11 cannot be positioned by the right first wire end positioning block 42; if the first wire 11 is longer, although the connector 10 at the tail end of the first wire 11 can be positioned by the right first wire end positioning block 42, the first wire 11 is in a non-tightened state.

For another example, after the connector 10 at the head end of the first wire 11 and the connector 10 at the head end of the second wire 12 are positioned by the left first wire end positioning block 41, the second wire 12 passes through the three-hole tie band positioning block 2 and the two-hole tie band positioning block 3 to the left second wire end positioning block 81. If the second wire 12 meets the length standard, the O-type terminal 14 at the tail end of the second wire 12 can be just positioned by the left second wire end positioning block 81; if the second wire 12 is shorter, the O-type terminal 14 at the tail end of the second wire 12 cannot be positioned by the left second wire end The positioning block 81 is used for positioning; if the second wire 12 is long, although the O-type terminal 14 at the tail end of the second wire 12 can be positioned by the left second wire end positioning block 81, the second wire 12 is in a non-tightened state. When it is in a tight state, it will exceed the left second wire end positioning block 81, thereby realizing the detection of the second wire 12; the same principle is used to realize the detection of the third wire 13 through the right first wire end positioning block 42, the three-hole tie band positioning block 2, the two-hole tie band positioning block 3 and the left second wire end positioning block 82.

[0042] In order to realize the positioning of the adjacent connectors 10 at the head end of the first wire 11 and the connector 10 at the head end of the second wire 12, as well as the adjacent connectors 10 at the tail end of the first wire 11 and the connector 10 at the head end of the third wire 13, the left first wire end positioning block 41 and the right first wire end positioning block 42 are both provided with connector clamping devices, and the connector 10 at the head end of the first wire 11 and the connector 10 at the head end of the second wire 12 are combined and clamped in the connector clamping device of the left first wire end positioning block 41, and the connector 10 at the tail end of the first wire 11 and the connector 10 at the head end of the third wire 13 are combined and clamped in the connector clamping device of the right first wire end positioning block 42. Here, the connector clamping device can realize the simultaneous clamping of two connectors 10, that is, the connector clamping device integrates the positioning function of the ends of two wires. For example, the connector clamping device of the right first wire end positioning block 42 integrates the positioning functions of the tail end connector 3 of the first wire 11 and the head end connector 3 of the third wire 13. The right first wire end positioning block 42 is not only the tail end positioning block of the first wire 11, but also the head end positioning block of the third wire 13.

When the left connector tail end stop block 6 slides back and forth along the left stop block avoidance groove 61, the left guide rod 63 slides along the left guide bar hole 64, and the left guide bar hole 64 guides and limits the left guide rod 63; after the left connector tail end stop block 6 slides and avoids along the left stop block avoidance groove 61, the left return spring 62 is used to reset the left connector tail end stop block 6 to stop at the tail end of the connector.

[0046] On the front side of the left connector tail end stop block 6 and the right connector tail end stop block 5, the left connector tail end stop block 6 and the right connector tail end stop block 5 are both provided with extrusion slopes, and the plug-in 7 is provided on the rear side of the left connector tail end stop block 6 and the right connector tail end stop block 5, and the plug-in 7 is provided with two connector 10 sockets, which can realize the simultaneous plug-in of two connectors 10.

[0047] When in use, taking the left first wire end positioning block 41 as an example, the connector 10 at the head end of the first wire 11 and the connector 10 at the head end of the second wire 12 are inserted into the plug-in 7 side by side and in parallel from the front side of the connector tail end stop block. During the insertion process, the connectors 10 at the head ends of the first wire 11 and the second wire 12 push the extrusion inclined surface of the right connector tail end stop block 5 and the extrusion inclined surface of the left connector tail end stop block 6 respectively, and the right connector tail end stop block 5 and the left connector tail end stop block 6 are subjected to force to slide and avoid along the stop block avoidance groove (the guide rod slides along the guide bar hole); after the connector tail end stop block is freed from the connector constraint, the right return spring 52 is reset, so that the right connector tail end stop block 5 slides and resets along the right stop block avoidance groove 51, so that the right connector tail end stop block 5 is blocked at the tail end of the connector, and the left return spring 62 is reset, so that the left connector tail end stop block 6 slides and resets along the left stop block avoidance groove 61, so that the left connector tail end stop block 6 is blocked at the tail end of the connector. Similarly, the right first wire end positioning block 42 is used to position the connector 10 at the tail end of the first wire 11 and the connector 10 at the head end of the third wire 13 .

[0048] In order to locate and detect the O-type terminals 14 at the tail ends of the second wire 12 and the third wire 13, the left second wire end positioning block 81 and the right second wire end positioning block 82 are both provided with terminal connection grooves 91, and terminal connection columns 9 are both provided in the terminal connection grooves 91. The terminal connection columns 9 are used to detect the inner diameter of the wire O-type terminals, and the terminal detection grooves 91 are used to detect the outer diameter of the wire O-type terminals.

During use, if the inner diameter of the O-type terminal 14 of the second wire 12 is too large, after it is placed in the terminal detection groove 91 of the left second wire end positioning block 81, there will be a gap between the O-type terminal 14 of the second wire 12 and the terminal connecting column 9 of the left second wire end positioning block 81; if the inner diameter of the O-type terminal is too small, it cannot be mounted on the terminal connecting column 9 of the left second wire end positioning block 81; if the outer diameter of the O-type terminal is too large, it cannot be placed in the terminal detection groove 91 of the left second wire end positioning block 81; if the outer diameter of the O-type terminal is too small, after it is mounted on the terminal connecting column 9 of the left second wire end positioning block 81, there will be a gap between it and the terminal detection groove 91 of the left second wire end positioning block 81; therefore, through the terminal connection groove 91 and the terminal connection column 9 of the left second wire end positioning block 81, the size of the O-type terminal at the tail end of the second wire 12 can be quickly detected to ensure product quality. Similarly, the terminal connection groove 91 and the terminal connection column 19 of the right second wire end positioning block 82 can also detect the inner diameter and outer diameter of the O-type terminal 14 of the third wire 13 .

[0050] In order to realize the tests of wire conduction, insulation resistance, contact resistance, etc., a copper terminal is arranged in the jack of each connector of the plug-in, and the copper terminal of the plug-in is provided with an arc protrusion. The copper terminal of the plug-in is used to connect with the copper terminal of the connector. The arc protrusion can increase the contact area between the copper terminal of the plug-in and the copper terminal of the connector. The copper terminal of the plug-in and the terminal connecting column are respectively connected with test leads. By connecting the test leads at both ends of each section of the wire, the test functions of wire conduction, insulation resistance, contact resistance, etc. are realized.

[0051] Specifically, the left first wire end positioning block 41 is provided with a first test lead 17a and a second test lead 16a, and the right first wire end positioning block 42 is provided with a third test lead 17b and a fourth test lead 16b.
