Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness processing, and more specifically to tooling plates for automotive wiring harness processing. Background Technology

[0002] Wiring harnesses are the wiring components in a car's electrical system that connect various electrical devices. Battery cables, in particular, often need to be bent into specific routes during use to conform to the battery cable layout within the vehicle.

[0003] Current methods for adjusting the bending direction of battery cables often involve manually bending them after comparing and measuring the cable against a drawing on a fixture. This process is cumbersome and requires repeated checks of the fixture drawing to adjust the bending angle. Currently, there is a lack of a fixture suitable for the bending direction of battery cables.

[0004] CN107226046A discloses a high-voltage wire harness bending and fixing device. Although this device can achieve bending, the bending fixture of this structure has the following defects:

[0005] 1) It can only achieve processing and forming at one bending angle, and cannot be applied to the bending processing of battery cables with multiple bending sections.

[0006] 2) There is no terminal positioning and fixing mechanism, so it is impossible to guarantee the corresponding distance between the bend and the terminal, and it is not suitable for bending battery cables with multiple bends. Summary of the Invention

[0007] In view of the problems existing in the prior art, the present invention provides a bending tooling plate for automotive battery cables, which solves at least one of the above-mentioned technical problems.

[0008] The technical solution of the present invention is: a tooling plate for bending automotive battery cables, comprising a tooling plate body, characterized in that a left end bending mechanism and a right end bending mechanism for the wire harness are installed at the left and right ends of the tooling plate body.

[0009] The left-end bending mechanism of the wire harness includes a left-side terminal fixing post, a left bending post, and a left bending guide post;

[0010] The left bending column is vertically arranged and detachably installed on the tooling plate body. The left bending guide column is L-shaped and detachably installed on the tooling plate body. The left bending guide column includes a vertically arranged left column and a horizontally arranged left crossbar. The left column is detachably connected to the tooling plate body, and the left crossbar is used for the bending point.

[0011] The left terminal fixing post is detachably installed on the tooling plate body, and the left terminal positioning post is used for longitudinally inserting the left terminal of the battery cable.

[0012] The right-end bending mechanism of the wire harness includes a right-side terminal fixing post, a right bending post, and a right bending guide post;

[0013] The right-bending guide post is L-shaped and includes a vertically arranged right column and a horizontally arranged right crossbar. The right crossbar is used at the bend.

[0014] The right-bending column is detachably mounted on the tooling plate body, and the right-bending column is located on the periphery of the right column, with the right crossbar extending beyond the top of the right-bending column;

[0015] The right terminal fixing post is detachably connected to the tooling plate body, and the right terminal positioning post is used for longitudinally inserting the right terminal of the battery cable.

[0016] The upper surface of the tooling plate body is covered with a layer of drawings.

[0017] This invention optimizes the tooling plate structure, facilitating rapid prototyping of the bending structures at both ends of the battery cable. The detachable bending mechanisms at the left and right ends of the cable harness allow for easy adjustment to meet different drawing requirements, resulting in high versatility. Furthermore, the combination of the left and right terminal fixing posts effectively limits the relative position of the terminals and the bending points, greatly ensuring processing accuracy and guaranteeing the precise positioning of the bends.

[0018] More preferably, the tooling plate body includes a hollow cavity, and a test circuit is installed in the hollow cavity. The test circuit includes a power supply, an ammeter, a resistor and a test switch arranged in series.

[0019] The test circuit includes branches that match the number of threaded holes;

[0020] Each branch is equipped with one of the aforementioned test switches and a resistor, and the resistance value of each branch is different;

[0021] The test switch includes a spring plate located directly below the threaded hole; a spring is connected to the lower end of the spring plate, and the bottom of the spring is connected to the bottom of the hollow cavity.

[0022] The test switch includes adjacent slide rails, which are slidably connected to the spring pressure plate. The slide rails include an insulating part, a conductive part, and an insulating part arranged sequentially from top to bottom.

[0023] The slide rail is fitted with a conductive element, which is used as the test switch to connect to both ends of the test circuit.

[0024] This invention involves pressing down a spring plate after the component is screwed into the threaded hole. This causes the spring plate to pass through a conductive part during the pressing process, during which the measurement circuit performs a test. The position of the installed component is determined by the ammeter reading. When the component is rotated into place, the spring plate is located in the insulating part, thus disconnecting the test switch. At this point, the measurement of the next component can begin.

[0025] More preferably, the left terminal fixing post, the left bending post, and the right terminal fixing post all include vertically arranged rods. The rods include smooth rods and threaded rods arranged vertically. The threaded rods are threadedly connected to a nut, and the nut abuts against the tooling plate body.

[0026] This facilitates the fixing of various components onto the tooling plate.

[0027] More preferably, the left column of the left bending guide column and the right column of the right bending guide column both include an upper and lower optical axis portion and a threaded portion, and the threaded portion is threadedly connected to the nut that abuts against the tooling plate body.

[0028] More preferably, the right-bent column is a hollow sleeve, which is inserted into the nut from the top and bottom.

[0029] This facilitates the relative fixation of the right-bending column.

[0030] More preferably, the left terminal fixing post is located in front of the left bending post, and the left bending guide post is located behind the right side of the left bending portion;

[0031] The left-bending guide post and the right-side terminal fixing post are arranged side by side;

[0033] The right crossbar of the right-bending guide post tilts backward from left to right.

[0034] It facilitates layout design.

[0035] More preferably, the tooling plate body has a left positioning groove, which is used to insert the left terminal of the battery cable, and the left positioning groove is arranged adjacent to the left terminal fixing post;

[0036] The tooling plate body has a right positioning groove, which is used to insert the right side terminal of the battery cable. The right positioning groove is arranged adjacent to the right side terminal fixing post.

[0037] Improve the fixing effect on the terminals.

[0038] More preferably, the battery cable includes a left-side terminal, a first bend, a second bend, a third bend, a fourth bend, and a right-side terminal connected sequentially from left to right;

[0039] The left-bending column is used to shape the bending angle between the first bending part and the second bending part;

[0040] The left crossbar of the left bending guide post is used to form the bending angle between the second bending part and the third bending part;

[0041] The right crossbar of the right-bending guide post is used to form the bending angle between the third bending part and the fourth bending part;

Detailed Implementation

[0049] The present invention will now be further described with reference to the accompanying drawings.

[0050] See Figures 1 to 3Specific embodiment 1: A bending fixture for automotive battery cables includes a fixture body 1. A left-end bending mechanism and a right-end bending mechanism for the wiring harness are installed at both ends of the fixture body 1. The left-end bending mechanism includes a left-side terminal fixing post 2, a left bending post 3, and a left bending guide post 4. The left bending post 3 is vertically arranged and detachably installed on the fixture body 1. The left bending guide post 4 is L-shaped and detachably installed on the fixture body 1. The left bending guide post 4 includes a vertically arranged left column and a horizontally arranged left crossbar. The left column is detachably connected to the fixture body 1. The connection is detachable. The left crossbar is used for bending. The left terminal fixing post 2 is detachably mounted on the tooling plate body 1. The right end bending mechanism of the wire harness includes a right terminal fixing post 5, a right bending post 6, and a right bending guide post 7. The right bending guide post 7 includes a vertically arranged right column and a horizontally arranged right crossbar, which is used for bending. The right bending post 6 is detachably mounted on the tooling plate body 1, and the right bending post 6 is located outside the right column, with the right crossbar extending beyond the top of the right bending post 6. The right terminal fixing post 5 is detachably connected to the tooling plate body 1. The upper surface of the tooling plate body 1 is covered with a drawing layer. This invention optimizes the structure of the tooling plate to facilitate the rapid prototyping of the bending structure at both ends of the battery cable. The detachable left and right end bending mechanisms of the wire harness facilitate adjustments according to different drawing requirements, resulting in high versatility. Meanwhile... By combining the left terminal fixing post 2 and the right terminal fixing post 5, the relative position of the terminal and the bend is limited, which greatly ensures the processing accuracy and at the same time ensures the positioning of the bend.

[0051] The drawing layer includes labels to show the left and right terminal structures of the battery cables. This prevents misalignment. The drawing layer serves as a screen for drawings or projected images, facilitating different presentation formats for the drawings. Figure 1 The projected structure of the left and right terminals is shown in the drawing layer to avoid incorrect installation.

[0052] The tooling plate body 1 has a matrix of threaded holes for threaded connection of the left terminal fixing post 2, left bending post 3, left bending guide post 4, right terminal fixing post 5, right bending post 6, and right bending guide post 7. This allows the positions of different components to be adjusted according to actual needs.

[0053] The left terminal fixing post 2, the left bent post 3, and the right terminal fixing post 5 all include vertically arranged rods. Each rod includes a smooth rod positioned vertically and a threaded rod. The threaded rod is threadedly connected to a nut, which abuts against the fixture plate body 1. This facilitates the fixing of each component onto the fixture plate.

[0054] The left upright of the left bending guide post 4 and the right upright of the right bending guide post 7 both include an upper and lower optical shaft portion and a threaded portion, with the threaded portion threadedly connected to a nut that abuts against the tooling plate body. The right bending post 6 is a hollow sleeve, which is inserted into the nut from above and below. This facilitates the relative fixation of the right bending post 6.

[0055] The left terminal fixing post 2 is located to the left front of the left bending post 3, and the left bending guide post 4 is located to the right rear of the left bending section; the left bending guide post 4 and the right terminal fixing post 5 are arranged side by side; the right bending guide post 7 is located to the right front of the right terminal fixing post 5; the right horizontal bar of the right bending guide post 7 tilts backward from left to right. This facilitates the layout.

[0056] The fixture plate body 1 can have a left positioning groove for inserting the left terminal of the battery cable. The left positioning groove is adjacent to the left terminal fixing post 2. The fixture plate body can also have a right positioning groove for inserting the right terminal of the battery cable. The right positioning groove is adjacent to the right terminal fixing post 5. This improves the fixing effect on the terminals. Both the left and right terminals have wiring portions with wiring holes. The outer edge of the wiring portion has a bent flange. The flange is used to insert into the left or right positioning groove. The sum of the depth of the left and right positioning grooves and the axial length of the nut is less than the length of the flange.

[0057] Adhesive tape is wrapped around the upper end of the left bending post 3, the upper end of the left bending guide post 4, and the right crossbar of the right bending guide post 7. This reduces wear on the wiring harness.

[0058] See Figure 2 as well as Figure 3 The battery cable includes a left terminal 95, a first bend 91, a second bend 92, a third bend 93, a fourth bend 94, and a right terminal 96 connected sequentially from left to right. The left bend post 3 is used to shape the bending angle between the first and second bends; the left crossbar of the left bend guide post 4 is used to shape the bending angle between the second and third bends; the right crossbar of the right bend guide post 7 is used to shape the bending angle between the third and fourth bends; and the right bend post 6 is used to shape the fourth bend. The fourth bend is a U-shaped bend or an arc-shaped bend.

[0059] Instructions for use: First, insert the left terminal of the left end of the battery cable into the left terminal positioning post. Then, sequentially loop the battery cable around the outside of the left bending post 3 and the left crossbar of the left bending guide post 4 to form the left terminal, the first bend, the second bend, and the third bend in sequence. Then, remove the battery cable.

[0060] Then, insert the right terminal of the battery cable into the right terminal positioning post, and then sequentially loop the battery cable onto the outside of the right bend post 6 and the right crossbar of the right bend guide post 7, thereby forming the right terminal, the fourth bend and the third bend connected in sequence.

[0061] For a specific embodiment 2, see [link / description]. Figure 4 Based on specific embodiment 1, the tooling plate body includes a hollow cavity, within which a test circuit is installed. The test circuit includes a power supply, an ammeter, a resistor, and a test switch connected in series. The test circuit includes branches matching the number of threaded holes. Each branch is equipped with a test switch and a resistor, and the resistance value of each branch is different. The test switch includes a spring pressure plate 81, located directly below the threaded hole. A spring 82 is connected to the lower end of the spring pressure plate, and the bottom of the spring 82 is connected to the bottom of the hollow cavity. The test switch includes adjacent slide rails, which are slidably connected to the spring pressure plate. The slide rails include an upper insulating part, a conductive part 83, and a lower insulating part arranged sequentially from top to bottom. A conductive element 84 is sleeved around the slide rail, serving as the test switch connected to both ends of the test circuit. The conductive element contacts the upper insulating part, the lower insulating part, and the conductive part. The guide element is slidably connected to the slide rail longitudinally, facilitating the detachment of the guide element and the slide rail. This invention involves pressing down a spring plate after the component is screwed into a threaded hole. This causes the spring plate to pass through a conductive part during the pressing process, during which a measurement circuit is tested. The position of the installed component is determined by the ammeter reading. When the component is fully rotated, the spring plate is located in the insulating part, thus disconnecting the test switch. At this point, the measurement of the next component can begin. A guide post is installed at the bottom of the hollow cavity, and the spring is sleeved around the guide post. The hollow cavity includes a bottom plate with upper and lower sections and a groove with an open upper end. The bottom plate and the groove with the open upper end are detachably connected to form the hollow cavity. A test circuit is installed on the groove.

[0062] In specific embodiment 3, based on specific embodiment 1, two opposing clamping plates are slidably connected to both the left and right crossbars. The two clamping plates are joined to form a tubular structure, facilitating the clamping and support of the vertically positioned bent end of the battery cable. A bracket is mounted on the tooling plate, a winding roller is mounted on the bracket, a pull rope is mounted on the winding roller, and a suspension component is mounted on the pull rope. The suspension component is used to suspend and support the terminals, facilitating the suspension and support of the terminals and achieving bending and shaping support.

[0063] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
