Description

Technical Field

[0001] The utility model relates to the field of wiring harness function loop detection, in particular to wiring harness function loop detection in the automobile industry, and specifically to a wiring harness function and loop detection tool. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness generally refers to the contact terminal (connector) made of copper material, which is crimped with the wires and cables, and then the insulator is plastic-pressed on the outside or a metal shell is added, etc., and the wiring harness is bundled to form a component connecting the circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing and downstream application industries. The wiring harness is widely used and can be used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc.

[0003] At present, related fault problems that occur during the use of automobiles have become the focus of people's attention; among them, automobile wiring harness failure is one of the focus issues. Automobile wiring harnesses are mainly composed of wires, connectors, wrapping tapes and other auxiliary materials. They are the carriers of controlling automobile electrical signals. They have complex structures and diverse functions. They are called the "automotive nerves" of the whole vehicle. Automobile wiring harnesses are one of the most critical components inside a car. Their quality, safety and reliability have a significant impact on the quality of the car. If the wiring harness fails, it will cause signal transmission failure and functional equipment to lose its function; or the contact resistance is too large to heat up and catch fire; or short circuit and catch fire; or insulation layer fails and leaks. Therefore, in order to ensure the quality, safety and reliability of automobile wiring harnesses, it is very important to detect automobile wiring harnesses on the production line or before users use them.

[0004] The traditional method in the industry is to design different tooling modules to detect functions or circuits according to different wiring harness connectors. However, the consistency of the wiring harness itself is very low, resulting in a large number of connector specifications, which cannot be universal, or can only be universal in a small part, and the replaceability is poor. Once the wiring harness connector is replaced, a new tooling module must be redesigned and made to detect the function or circuit, which is time-consuming and labor-intensive, and the replaced tooling module is basically in an abandoned state, which is not conducive to reducing enterprise costs. Utility Model Content

[0005] The purpose of the utility model is to overcome one or more deficiencies in the prior art and to provide an improved wiring harness function and loop detection tooling, which can replace different detection components according to different wiring harness connectors, while some detection components can continue to be used, which not only realizes fast switching but also greatly reduces the testing cost.

[0012] According to some preferred aspects of the present invention, the first detection component further includes a fourth wiring terminal, the fourth wiring terminal is electrically connected to the connecting member via a wire, and the fourth wiring terminal can be plugged into the third wiring terminal.

[0013] In some preferred embodiments of the present invention, a positioning conductive hole is provided on the first base, and a positioning connecting column is provided on the second base, and the positioning connecting column can be inserted into the positioning conductive hole.

[0014] According to some preferred aspects of the present invention, the positioning connection column is a hollow structure with a clearance through hole formed inside.

[0020] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0021] Based on the problems of poor versatility, inability to reuse tooling, and serious waste in the process of existing harness function and loop detection, the utility model innovatively designs the detection tooling, so that it is roughly divided into two detection components that can be detachably connected to each other, wherein the first detection component realizes the purpose of connecting with the harness connector, and the second detection component realizes the purpose of connecting with the external or other functional modules, and then the electrical connection relationship between the two is connected by connecting terminals that can be plugged into each other, so as to avoid the defect of combining and assembling all components in a fixed setting in the prior art, because once a different harness connector needs to be replaced for harness detection, a new detection tooling needs to be replaced, which needs to be redesigned and time-consuming and labor-intensive to produce, and the original ones are basically all abandoned; the utility model provides a quickly replaceable assembly, when the harness connector is replaced, only the first detection component needs to be replaced, and the second detection component can continue to be used, or when the harness connector is the same, when a different detection function is replaced, only the second detection component needs to be replaced, and the first detection component can be retained, which greatly saves the detection cost and avoids time-consuming design.

[0032] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0033] In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0035] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 5 As shown, this example provides a wiring harness function and loop detection tool, which includes a first detection component 100, a second detection component 200 detachably connected to the first detection component 100, and a wiring harness function and loop detection tool. Figure 1 It can be seen from this viewing angle that the first detection component 100 is basically located above most of the components of the second detection component 200, and the two remain connected.

[0037] Specifically, in this example, the first detection component 100 includes a first base 110 provided with a wiring harness connector mounting groove 111, a connector 120, and a first terminal 130. The connector 120 is provided on the first base 110 and is used to be electrically connected to the wiring harness connector 500. The first terminal 130 is electrically connected to the connector 120 through a wire 300.

[0038] The second detection component 200 includes a second base 210 and a second terminal 220 that can be plugged into the first terminal 130; the second base 210 is detachably connected to the first base 110, and the second terminal 220 is electrically connected to the outside through a wire 300. In this example, some components are selectively concentrated in the first detection component 100, and some other components are selectively concentrated in the second detection component 200. Under such a structural setting, only the two detection components need to be disassembled or connected to each other to achieve the replacement of some detections. At the same time, in this example, the detachable connection relationship between the first detection component 100 and the second detection component 200 at least includes the detachable connection between the first base 110 and the second base 210 as a carrier, and the detachable plugging of the two terminals for realizing the electrical connection relationship, which ensures the separability of the mechanical structure and the separability of the electrical connection relationship in the detection tooling, and further realizes that each detection component can be replaced or retained when necessary.

[0039] Furthermore, in this example, the second terminal block 220 is provided with a full-match plug interface required for wiring harness function and loop detection. The full-match plug interface can facilitate the second detection component 200 to be suitable for matching with basically all wiring harness connectors 500. Of course, if special functions need to be tested, different second detection components 200 can also be replaced while ensuring the same detachable connection relationship.

[0040] Further, in this example, the second detection component 200 also includes a third terminal 230, a circuit board 240 for at least power supply and / or conversion of electrical signals, a circuit board mounting groove 211 for mounting the circuit board 240 is provided on the second base 210, the third terminal 230 is electrically connected to the circuit board 240 through a wire 300, the circuit board 240 is electrically connected to the outside through the wire 300, and the third terminal 230 is provided with a full-match plug interface required for wiring harness function and loop detection. Specifically, the circuit board 240 for power supply and / or conversion of electrical signals can be an existing one, and its circuit design for power supply and / or conversion of electrical signals is not an improvement point of the utility model, and will not be described in detail here, and can be designed in an existing manner; this example only uses the circuit board to process one of the signals when at least two signals are required to be provided in some cases such as airtightness, switch pins, etc., such as converting electrical signals (sometimes it is necessary to convert 12V voltage into an output electrical signal of 24V voltage). In some cases, it is only for the purpose of providing power supply, and the purpose of the third terminal 230 is to cooperate with these wiring harness functions and loop detection. Of course, this example is mainly to provide a second detection component 200 with strong versatility. Therefore, even when the above-mentioned airtightness and other performances do not need to be tested for certain wiring harness connectors 500, the third terminal 230 and the circuit board 240 can also exist in the second detection component 200, but they do not play a role at this time. However, once the above-mentioned performance test is required, it is only necessary to replace the first detection component 100. At this time, the first detection component 100 is required to also include a fourth terminal 140, and the fourth terminal 140 is electrically connected to the connector 120 through the wire 300, and the fourth terminal 140 can be plugged into the third terminal 230.

[0041] Further, see Figure 5 As shown, the fourth terminal 140 is connected to the circuit inlet of the first terminal 130 through the wire 300. In this way, two signals are provided to the subsequent detection machine at the same time when these performance tests are performed. Some performance tests do not need to be processed by the circuit board, but are directly connected to the subsequent detection machine through the first terminal 130 and the second terminal 220. If some loop tests are performed, there is a situation where two adjacent plug interfaces need to be occupied, so that a loop is formed. Figure 5Only part of the connection relationship is shown as an example. In actual operation, the number of plug interfaces of the first terminal 130 can be adjusted according to the specific function or circuit required by the wiring harness; in this example, the first terminal 130 and the fourth terminal 140 can be both female terminals, and the second terminal 220 and the third terminal 230 can be both male terminals. Of course, the positions of the female terminals and the male terminals can also be swapped, even if the first terminal 130 and the fourth terminal 140 are both male terminals, the second terminal 220 and the third terminal 230 can be both female terminals.

[0042] As an option, in this example, n first detection components 100 and m second detection components 200 can be designed according to the specific functions or circuits that need to be detected in the wiring harness. In this way, it is only necessary to directly use the prepared detection components when needed, which can achieve faster switching; further, the first detection component 100 and the second detection component 200 can also be designed according to customer needs, and it is only necessary to retain the detachable connection relationship of this example. In this way, when upgrading, certain detection components can also be quickly switched or reused, which greatly saves the detection cost of the detection company and is also beneficial to improving the detection efficiency.

[0043] In this example, the first base 110 is provided with a positioning through hole 112, and the second base 210 is provided with a positioning connecting column 212, which can be inserted into the positioning through hole 112. Such a configuration is conducive to the guiding docking and relative stability after the first base 110 and the second base 210 are connected; further, the positioning connecting column 212 is a hollow structure with a clearance through hole 2121 formed inside. Since the second base 210 is provided with a circuit board 240, a connector 600 can be provided through the clearance through hole 2121 to realize power supply to the circuit board 240. Specifically, see Figures 1 to 4 As shown, in this example, the positioning connecting column 212 is inserted into the positioning conductive hole 112, so that the connector 600 can be exposed from the clearance hole 2121 along the positioning conductive hole 112, which is convenient for subsequent power supply. In addition, this setting simplifies the structure, helps to reduce the volume share, and makes the overall structure more regular.

[0044] Further, a first positioning boss 113 is provided on the first base 110, and a second positioning boss 213 is provided on the second base 210, and the first positioning boss 113 and the second positioning boss 213 can be arranged close to each other; the detection tooling also includes a locking assembly, and the locking assembly includes a locking hole 410 formed on the first positioning boss 113 and the second positioning boss 213, respectively, and a locking member 420 that can be inserted into the locking hole 410. The setting of the two positioning bosses is conducive to the first base 110 and the second base 210 being close to each other. When the locking assembly is further used to lock the two together, the two can achieve better stability of combination and avoid unexpected phenomena such as shaking. As an option, in this example, the locking hole 410 is a bolt hole, and the locking member 420 is a bolt. The setting of the locking assembly is easy to implement, and it is convenient to disassemble and lock, so that the first base 110 and the second base 210 can be quickly disassembled and installed.

[0045] In this example, a tracheal tube is provided on the first base 110, and the detection tooling also includes a first tracheal connecting piece and a second tracheal connecting piece that can be detachably connected and connected with the first tracheal connecting piece. The first tracheal connecting piece is connected to the tracheal tube through the trachea, and the second tracheal connecting piece is connected to the outside through the trachea. For example, the detection tooling of this example also includes a locking cylinder 150, which is used to firmly lock the wiring harness connector 500 in the wiring harness connector mounting groove 111 after it is installed in the wiring harness connector mounting groove 111, to ensure stability and the connection of some parts, for example, after locking the limit, it can be beneficial to realize the electrical connection between the connector 120 and the wiring harness connector 500, and the air source required by the locking cylinder 150 can be obtained from the outside through the connection and conduction of the tracheal tube, the first tracheal connecting piece, and the second tracheal connecting piece. Similarly, in this case, the existence of the first tracheal connecting piece and the second tracheal connecting piece enables the first base 110 and the second base 210 to be quickly disassembled without being affected.

[0046] In this example, at least one strap limiting groove 214 is provided on the second base 210, for example, 2, 3, 4 or more strap limiting grooves 214 may be provided, and they may be arranged in sequence along the extension direction of the second base 210. The strap limiting grooves 214 are provided to facilitate binding part of the wires 300 or the trachea to the second base 210, so that the wiring can be more regular and the messy arrangement of the wires and trachea can be avoided.

[0047] In summary, this example is based on the problems of poor versatility, inability to reuse tooling, and serious waste in the process of existing harness function and loop detection. The detection tooling is innovatively designed to be roughly divided into two detection components that can be detachably connected to each other, wherein the first detection component realizes the purpose of connecting with the harness connector, and the second detection component realizes the purpose of connecting with the external or other functional modules, and then the electrical connection between the two is connected by connecting terminals that can be plugged into each other, thus avoiding the defect of combining and assembling all components in a fixed manner in the prior art, because once a different harness connector needs to be replaced for harness detection, a new detection tooling needs to be replaced, which needs to be redesigned and time-consuming and labor-intensive to produce, and the original ones are basically all abandoned; the utility model provides a quickly replaceable assembly, when the harness connector is replaced, only the first detection component needs to be replaced, and the second detection component can continue to be used, or when the harness connector is the same, when a different detection function is replaced, only the second detection component needs to be replaced, and the first detection component can be retained, which greatly saves the detection cost and avoids time-consuming design.

[0048] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
