DETAILED DESCRIPTION

[0031] The following will be combined with the Figure 1 to the Figure 13, further illustrate the specific embodiments of the utility model discloses a combined harness detection test bench structure. The utility model discloses a combined harness detection test bench structure is not limited to the following embodiment description.

[0032] The prior art of harness detection device can refer to Chinese patent application "a line matching method, device, electronic equipment and storage medium (application number: CN202310877989.3)" and other prior art documents. The above-mentioned Chinese patent application discloses an intelligent harness detection device, which comprises a host computer and a jig that can communicate. Compared with the traditional technology, the patent application can realize the automatic matching between the host computer and the jig. The following embodiments provide a specific embodiment of a combined harness detection test bench structure and a combined jig, which is especially suitable for use with the Chinese patent. After the above-mentioned Chinese patent is cited in this patent, it is considered that all the contents recorded in it have been recorded in this patent. Embodiments

[0033] The present embodiment gives a specific embodiment of a combined harness detection test bench structure.

[0034] As shown in Figures 1 to 5 , Figure 12 A combined harness detection test bench structure, comprising a test bench frame 2, the upper part of the test bench frame 2 is a panel part, the panel part of the test bench frame 2 is a hollow structure, and a plurality of longitudinal beam structures 211 are installed in parallel inside the hollow structure, so that the jig installation space 210 for installing the jig assembly 1 is formed between the two adjacent longitudinal beam structures 211, and the longitudinal beam structure 211 is provided with a bolt hole for fixing the jig assembly 1.

[0035] Specifically, the test bench frame 2 is a support part of the combined harness detection test bench structure, which can adopt a frame structure spliced by metal beams, and the splicing mode can adopt fixed connection such as welding or detachable connection mode such as bolt fixing. The outer side of the frame can be covered or wrapped with a metal plate to shield and protect the inside. Preferably, the test bench frame 2 has an approximate cuboid structure, and its height is appropriate for users to stand in front of the combined harness detection test bench structure to facilitate operation of the upper panel part. The overall length of the conventional test bench frame 2 (from the user's perspective when standing in the operating position, left and right direction) is usually between 1-4 meters according to the test requirements. Since the device given in the patent adopts a splicable structure, the width thereof can be set to about 1 meter. The width (front and back direction) is usually about 1 meter, which constitutes a "basic unit". The upper part of the test bench frame 2 is a panel part, which is the main operating part for users. The process of manually installing or dismounting cable plugs is completed on the panel part. The panel part as a whole has a hollow structure, and a plurality of longitudinal beam structures 211 are installed in parallel inside. Of course, a horizontal beam structure can also be used for installation, which belongs to an equivalent technical solution. The distance between the plurality of longitudinal beam structures 211 is designed to be hollow, and the distance is just enough to install the jig assembly 1. One row of jig assemblies 1 can be installed between every two longitudinal beam structures, which provides a universal jig installation space for the jig assembly. Preferably, the jig assembly 1 includes a jig 10 and a base 11. The user first installs the base 11 of the jig assembly 1 into the jig installation space, and then arranges the bases tightly to occupy the entire hollow space between the two longitudinal beams. During subsequent cable testing, the user can flexibly add or replace different types of jigs 10 according to test requirements in a plug-in manner, which is quick and convenient. When the jig position corresponding to a base does not need to be installed according to test requirements, a jig placeholder shell (a jig shell with only a shell but no functional assembly) or a cover plate can be installed to close the space.

[0036] In one embodiment, the jig assembly 1 includes a jig 10 and a base 11, and the jig 10 can be plug-in combined in the base 11. The base 11 adopts a U-shaped structure, and the two side edges of the base 11 are provided with outwardly protruding ears 116. The outer side of the base 11 is located below the ears 116 to form a groove-shaped structure 1160. The base 11 is inserted into the jig installation space 210 between the two longitudinal beam structures 211, and the groove-shaped structure 1160 of the base 11 is respectively clamped on the two longitudinal beam structures 211, and the ears 116 and the longitudinal beam structures 211 are bolted through the bolt holes.

[0037] Specifically, the jig 10 and the base 11 are separable structures, and the jig panel structure needs to be adapted to different models of cable plugs, so the jig panel structure is different, but the part of the jig 10 inserted into the base 11 adopts the same specification and size, which can be matched with the base 11; the base 11 adopts the general specification and size matched with the insertion part of the jig 10. In actual use, the user can first install the base 11 on the panel part of the test bench frame 2, and electrically connect the base 11 with the host computer and the like. In the future, when actually carrying out cable testing work, only the jig 10 needs to be installed and replaced by plugging, without the need to disassemble the base 11. For a specific embodiment of the jig assembly 1, reference can be made to Patent Embodiment II.

[0038] In one embodiment, the test bench frame 2 is provided with butt joint fixing devices 207 on both sides, which are used to butt joint and fix two adjacent test bench frames 2 when connecting multiple test bench frames 2, wherein the butt joint fixing devices 207 are a sub-mother buckle structure, and the butt joint fixing devices 207 on both sides of the test bench frame 2 are in the same horizontal position, one side being a sub-buckle structure and the other side being a mother buckle structure; when two test bench frames 2 are connected, the sub-buckle structure on one side of one test bench frame 2 can be clamped in the mother buckle structure on the other side of the other test bench frame 2, so that the sub-buckle structure and the mother buckle structure are buckled with each other.

[0039] Specifically, the wire harness detection test bench in the prior art is usually set to a fixed width structure, which limits the maximum number of jigs that can be installed on the panel part. Because different cables have different testing requirements (different numbers of plugs), enterprises often need to equip multiple wire harness detection test benches of different lengths and different numbers of detection ports, such as 1 meter wide 72 ports, 5 meters wide 450 ports, etc. This not only increases the equipment investment of enterprises, but also requires enterprises to provide a large number of factory workshops to erect these equipment. In the present embodiment, the butt joint fixing devices 207 can be used to realize the combined connection of multiple test bench frames 2. Specifically, the test bench frame 2 can be set to a unified smaller size "basic unit", for example, 1 meter wide 72 ports. When the user needs more detection ports in actual work, multiple "basic units" can be combined into a whole in a "splicing" manner to meet the detection requirements. For example, five "basic units" are combined into a whole of 5 meters 360 ports. After multiple devices are combined, the host computer, electrical interface and the like between multiple devices are connected through wired or wireless mode, so that multiple devices can be operated coordinately, thereby meeting the detection requirements of more detection ports.

[0040] In one embodiment, the front end of the test bench frame 2 is provided with a slope structure gradually inclined upward from front to back, and the lower part of the front end of the test bench frame 2 is provided with a slope structure gradually inclined inward from top to bottom.

[0041] Specifically, the front end of the test bench frame 2 refers to the position close to the user's body on the upper part of the test bench frame 2 when the user stands in the equipment operation position. The top of the front end of the test bench frame 2, i.e. the part of the panel close to the user, is provided with a slope structure, so that the panel part is inclined to the user, facilitating the user to operate the jigs installed on the panel part. The lower part of the front end of the test bench frame 2 is provided with a slope structure gradually inclined inward from top to bottom, which is to provide space for the user's legs and feet, so that the user's body is closer to the test bench frame 2 when operating the equipment, reducing the fatigue caused by the user's body bending, and making the user more comfortable when operating the equipment.

[0042] In one embodiment, a plurality of indicator lights 204 are installed on the surface of the test bench frame 2 at a position above and / or below the jig installation space 210, and / or at a position left and / or right of the jig installation space 210; the indicator lights 204 are arranged in the same vertical column and / or the same horizontal row as the jig assemblies 1 installed in the jig installation space 210.

[0043] Specifically, the position where the cable plug is connected to the jig panel structure on the jig in the prior art is usually provided with a prompt indicator light, which can be controlled by the host computer to prompt the user to pay attention to a specific target jig. The events prompted include, for example, 1) the jig is the target jig corresponding to the next plug to be operated, and 2) the plug corresponding to the jig has an abnormality. By changing the on / off state / color / blink frequency of the prompt indicator light, the user's attention can be attracted, thereby helping the user to quickly find the jig. However, when the user actually performs cable testing, the indicator light of the jig is often obscured by the plug and the complex structure of the cable placed on the panel portion, and the user cannot easily notice the state of the prompt indicator light. In particular, when multiple cables are tested in parallel, the problem of obscuring is more prominent. Therefore, the embodiment adopts the mode of arranging the indicator light on the upper and lower sides and the left and right sides of the test bench frame 2 in the jig installation space to assist in prompting the specific jig that needs to be paid attention to by the user. In this way, the user can quickly locate the target jig during the use of the wire harness testing device, thereby saving the user's operation time. For example, when the jig located in the third horizontal row of the second vertical column needs to be prompted, the indicator lights located at the upper and lower positions of the second vertical column are turned on (which can also be blinked, changed in color, etc.), and the indicator lights located at the left and right positions of the third horizontal row are turned on. Since the indicator lights are located around the panel portion and are not obscured by the cable, the user can quickly find the target jig by observing the indicator lights. The indicator lights are electrically connected to the host computer and are controlled by the host computer. The indicator lights receive the control signals of the host computer, thereby achieving the auxiliary prompting function.

[0044] In one embodiment, a storage compartment 206 is arranged on the left side of the upper part of the test bench frame 2. A cover is rotatably arranged above the storage compartment 206 by a hinge.

[0045] Specifically, the storage compartment 206 is a cavity structure embedded in the test bench frame 2. When the cover of the storage compartment 206 is closed, the cover is flush with the upper surface of the test bench frame 2. Since the testing requirements of different wire harnesses are different, the number of jigs to be installed is also different. When a jig installation position does not need to be installed, a cover plate or a jig placeholder shell can be installed to close the installation position, thereby ensuring that the panel portion is an integral plane. When a jig needs to be installed, the cover plate or the jig placeholder shell can be stored in the storage compartment 206 to avoid loss.

[0046] In one embodiment, a router installation space 202 for installing a router is arranged at the upper position of the side surface of the test bench frame 2. The cross section of the router installation space 202 forms an “L” shape, and the vertical end of the “L” shape of the router installation space 202 is open.

[0047] Specifically, on the one hand, the host of the wire harness detection device needs to communicate with the upper computer, and on the other hand, when multiple wire harness detection devices are used in combination, the hosts of each device also need to communicate with each other, so that the wire harness detection device needs to be provided with a wireless communication device (such as a WiFi antenna device, a wireless router, etc.). Compared with a physical communication line such as a network cable, wireless communication can break free from the constraints of cables and will be more convenient for users to use. However, since the structure of the wire harness detection test bench is usually composed of a closed metal frame and a plate, considering the shielding effect of metal on wireless signals, in the embodiment, an “L”-shaped router installation space 202 is provided, wherein the host of the WiFi antenna device or the host of the wireless router can be placed at the bottom of the “L”-shaped router installation space 202, and the antenna part for transmitting signals of the WiFi antenna device or the wireless router can protrude out of the metal frame structure of the wire harness detection test bench through the open space at the upper part of the “L”-shaped router installation space 202, which can be more conducive to signal transmission. At the same time, by providing the “L”-shaped router installation space 202, when multiple test bench frames 2 are used in combination, the WiFi antenna device or the antenna of the router in the router installation space 202 can be given a position and will not conflict with the antenna position.

[0048] In one embodiment, a maintenance door 208 is rotatably installed at the lower front end of the test bench frame 2 through a hinge.

[0049] Specifically, after the user opens the maintenance door 208, various functional devices, connection cables, air paths, etc. inside the test bench frame 2 can be seen and operated, which facilitates the user to maintain or install the internal devices of the test bench frame 2.

[0050] In one embodiment, a terminal connection channel 201 is provided on the side of the test bench frame 2, which is used to realize the communication connection channel of multiple test bench frames 2 when connected.

[0051] Specifically, when multiple test bench frames 2 are used in combination, the hosts of multiple wire harness detection devices need to establish communication to work together. The multiple hosts can communicate through wireless or wired means. Preferably, the terminal connection channel 201 can adopt a male-female plug structure, and the positions of the male plug and the female plug are matched. When two test bench frames 2 are docked and combined, the male plug is inserted into the female plug, and the communication connection channel between the two devices is established.

[0052] In one embodiment, universal wheels 209 are fixedly installed at the four corner positions of the bottom of the test bench frame 2 through bolts, which are used to move the test bench frame 2.

[0053] Specifically, by setting the universal wheel 209, the user can more conveniently move the test bench frame 2, thereby more conveniently realizing the connection combination of multiple test bench frames 2.

[0054] In one embodiment, the top of the test bench frame 2 is further provided with a display mounting position 205 for mounting a display.

[0055] Specifically, by setting the display mounting position 205, the display can be integrated into the wire harness detection device, thereby more facilitating the integration and integration of the wire harness detection device. Embodiment

[0056] The embodiment provides a specific implementation of a modular wire harness detection jig assembly for the first embodiment.

[0057] The wire harness detection jig is a key component of the wire harness detection device, and is mainly used to realize physical connection with the plug of the wire harness to be detected, establish circuit connection and air connection between the plug and the host of the wire harness detection device, and thus provide a detection environment for subsequent wire harness function and performance detection work. In actual work, each wire harness usually has multiple plug structures of multiple types, and the plug structures of different wire harnesses are more various. In order to realize the matching of different wire harnesses and different types of plugs, multiple types of jigs usually need to be preset in advance. In the prior art, the jig is usually fixedly connected to the operation surface of the wire harness detection device through a connecting piece (such as a bolt). In actual work, the user first selects the jigs required for detection one by one, then installs the corresponding jigs on the corresponding positions of the operation surface of the wire harness detection device by using the connecting piece, and then connects the electrical interfaces of the jigs to the circuit interfaces and air interfaces of the host of the wire harness detection device one by one through wires and air pipes, so as to finally realize the installation of all required jigs in the wire harness detection device. In order to realize the detection of different wire harnesses, the wire harness detection device needs to frequently adjust the number, type and position of the jigs, which requires the user to frequently disassemble and assemble the jigs and repeatedly connect the electrical interfaces. The jig in the prior art has the following defects: first, the disassembly and assembly of the jig are tedious, which leads to low work efficiency of the user; second, the interface structure of most wire harness plugs is complex, so the electrical connection between the jig and the host is also very complex, which leads to the user to easily make mistakes when manually connecting the wires and air pipes between the jig and the host.

[0058] The embodiment provides a specific implementation of a modular wire harness detection jig assembly for the first embodiment, as shown in Figures 5 to 13As shown, the tool 10 and the base 11 are provided, wherein the tool 10 is detachably and slidingly inserted into the inside of the base 11; the inside of the tool 10 is provided with a circuit and / or air path detection device, and a circuit and / or air path connecting mechanism is arranged between the tool 10 and the base 11, so that when the tool 10 and the base 11 are inserted, the circuit and / or air path of the tool 10 and the base 11 are communicated. Specifically, the tool 10 is inserted into the base 11 through the insertion (i.e. plug-in cooperation) mode, so as to realize the electrical connection (i.e. the connection of the circuit interface and the connection of the air path interface) between the electrical interface of the tool 10 and the base 11, and then the electrical connection between the tool 10 and the host of the wire harness detection device is realized through the electrical connection structure arranged on the base 11. The inside of the tool 10 is provided with a circuit and / or air path detection device, and the tool 10 is also provided with an interface matched with the plug of the wire harness to be detected to realize the butt joint with the plug. The circuit and / or air path detection device and the interface can be arranged according to the prior art, and do not belong to the scope of protection of the present patent.

[0059] The utility model embodiment provides a kind of tool assembly that can be used for wire harness detection, by providing the base 11 of general structure and connecting the base 11 in advance on the installation position of all tools of wire harness detection device, when subsequent installation or replacement of different tool 10, only once plug-in operation is needed for user, i.e. the installation or replacement of tool 10 can be realized, and the connection between the electrical structure of tool 10 and the host of wire harness detection device is realized simultaneously.

[0060] In one embodiment, the circuit connecting mechanism in the circuit and / or air path connecting mechanism includes two probe female boards 102 and two probe male boards 112, wherein the two probe female boards 102 are both mounted on the front end of the tool 10, and one of the two probe female boards 102 is perpendicular to the other probe female board 102 and located on the right lower side of the other probe female board 102; the two probe male boards 112 are both located in the inside of the front end of the base 11; the two probe male boards 112 correspond to the two probe female boards 102 in position, so that when the tool 10 and the base 11 are inserted, the two probe male boards 112 and the two probe female boards 102 are connected correspondingly, so that the circuit of the tool 10 and the base 11 is communicated.

[0061] Specifically, by arranging the probe female board 102 and the probe male board 112 used in cooperation, when the user inserts the tool 10 into the base 11, the circuit communication between the electrical interface of the tool 10 and the base 11 is automatically realized. The number of the probe female board 102 and the probe male board 112 can be 2, or 1 or more, and the number of corresponding terminals thereon is not limited, which can be flexibly arranged according to the specific number of terminals of the tool circuit interface, and all belong to the same or equivalent technical solutions or technical features of the present embodiment.

[0062] In one embodiment, the circuit and / or gas circuit connecting mechanism includes two first gas circuit interfaces 101 and two gas circuit connecting seats 110, wherein the two first gas circuit interfaces 101 are mounted on the front end of the jig 10, the two gas circuit connecting seats 110 are located inside the front end of the base 11, and the two first gas circuit interfaces 101 and the two gas circuit connecting seats 110 are positionally corresponding, so that the two first gas circuit interfaces 101 and the two gas circuit connecting seats 110 are connected corresponding when the jig 10 and the base 11 are inserted, and the gas circuit between the jig 10 and the base 11 is communicated.

[0063] Specifically, the jig generally needs to be provided with two groups of gas circuit interfaces, for example, the first gas circuit interface 101 and the gas circuit connecting seat 110 disclosed in the embodiment are used in cooperation, and the two are preferably in a quick docking manner to realize the plug-in cooperation between the jig 10 and the base 11. Generally, one of them is used to start the plug-in locking device of the jig to lock the plug to ensure the reliable connection between the plug and the jig during the detection process; the other is used to detect the air tightness of the plug. According to the actual application needs, other number of gas circuit interfaces and gas circuit connecting seats can also not be provided or provided, which all belong to the prior art and should be regarded as the same or equivalent technical solutions or technical features as the embodiment.

[0064] In one embodiment, one end of the gas circuit connecting seat 110 extends to the outside of the base 11 and is connected with the second gas circuit interface 111, and the side of the gas circuit connecting seat 110 located inside the base 11 is provided with a plug hole 1100 for the first gas circuit interface 101 to be inserted.

[0065] Specifically, by providing the second gas circuit interface 111, the gas circuit of the jig can be communicated with the gas circuit of the main machine. Since the base 11 is fixedly connected on the wire harness detection device and does not need to be frequently disassembled and replaced like the jig, the second gas circuit interface 111 does not need to be in a quick docking manner like the first gas circuit interface 101, for example, traditional connection modes such as clamp connection are all feasible.

[0066] In one embodiment, two locking pressing pieces 1101 are symmetrically installed inside the front end of the base 11 between the two air path connecting seats 110. The locking pressing pieces 1101 are elastic and rigid and have an L-shaped structure, so that the locking pressing pieces 1101 can be deformed by external force and return to the original state when the external force disappears. A hole structure that can coincide with the insertion hole 1100 is formed on the horizontal end of the locking pressing piece 1101. The horizontal ends of the two locking pressing pieces 1101 are respectively and slidingly inserted into the two air path connecting seats 110. The outer wall of the first air path interface 101 is provided with a locking hole 1010. When the jig 10 and the base 11 are inserted and combined, and the locking pressing pieces 1101 are not subjected to other external forces, the hole structure on the horizontal end of the two locking pressing pieces 1101 is misaligned with the insertion hole 1100, so that the edge of the hole structure is clamped in the locking hole 1010 on the first air path interface 101, thereby locking the first air path interface 101, i.e. locking the jig 10.

[0067] Specifically, a through hole 100 extending between the two locking pressing pieces 1101 is formed on the front side (i.e. the operation surface of the user for inserting the plug, which is opposite to the surface provided with the electrical interface and inserted into the base 11) of the jig 10. The user can insert a disassembly tool (such as a flathead screwdriver or the like) into the through hole 100. When the front end of the flathead screwdriver is inserted into the position between the two locking pressing pieces 1101, the flathead screwdriver is rotated, so that the front end of the flathead screwdriver is expanded on both sides, i.e. the horizontal ends of the two locking pressing pieces 1101 are simultaneously pressed and moved outward, until the two locking pressing pieces 1101 are squeezed to make the hole structure coincide with the insertion hole 1100, i.e. the horizontal end of the locking pressing piece 1101 is separated from the locking hole 1010 on the first air path interface 101. At this time, the first air path interface 101 is unlocked, i.e. the jig 10 is unlocked. At this time, the user can directly pull out the jig 10, thereby realizing the disassembly of the jig 10 from the base 11. Conversely, when the user needs to install the jig 10, the user only needs to directly insert the jig 10 into the base 11, and slightly press downward when the jig 10 is close to the bottom. The horizontal ends of the two locking pressing pieces 1101 are moved outward under the pressure of the front end of the first air path interface 101, until the first air path interface 101 is locked with the air path connecting seat 110. This structure has the following benefits: first, only one set of device is needed, which not only realizes the quick installation or disassembly between the first air path interface 101 and the connecting seat 110, but also simultaneously realizes the quick installation or disassembly between the jig 10 and the base 11, which is simple and convenient to operate; second, the disassembly between the two devices can be realized by using a special tool or a general flathead screwdriver, without the need to separately provide a special unlocking structure, so that the overall structure of the jig is more simple.

[0068] In one embodiment, one side of the jig 10 is provided with an inner shell guide groove 107 along the length direction, and the other side is provided with a jig guide rail 103. One side of the base 11 is provided with a base guide rail 117 along the length direction, and the other side is provided with a base guide groove 113. The base guide rail 117 corresponds to the inner shell guide groove 107.

[0069] Specifically, the jig guide rail 103 corresponds to the base guide groove 113, so that the alignment of the jig 10 is more accurate when the jig 10 is inserted into the base 11, thereby ensuring the accurate positioning of the relative position between the jig 10 and the base 11 after locking, and ensuring the stable communication between the circuit and / or the air circuit.

[0070] In one embodiment, the base guide groove 113 and the inner shell guide groove 107 are arranged in a staggered manner, or the widths of the base guide groove 113 and the base guide groove 113 are different.

[0071] Specifically, the above structure can ensure that the jig 10 will not be inserted in reverse when inserted into the base 11.

[0072] In one embodiment, the side surfaces of the jig 10 and the base 11 are provided with a plurality of heat dissipation holes 104 for assisting heat dissipation, and the outer wall of the base 11 adopts a grid structure.

[0073] Specifically, since the jig is internally provided with a circuit structure, there is a possibility of heating, so that the overall heat dissipation performance of the jig can be improved by providing the heat dissipation holes 104. At the same time, the heat dissipation holes 104 can also reduce the weight of the jig 10 without reducing the strength of the base.

[0074] In one embodiment, the base 11 adopts a U-shaped structure, and the two side edges of the base 11 are provided with outwardly protruding ear portions 116. The tail end of the jig 10 is provided with an inner shell tail plate 106, and the edges of the ear portions 116 and the inner shell tail plate 106 are provided with a plurality of mounting holes.

[0075] Specifically, by providing the ear portions 116 and the mounting holes thereof, the connection and fixation of the base 11 and the wire harness detection device can be achieved. Furthermore, by providing the inner shell tail plate 106 and the mounting holes thereof, the further connection and fixation between the jig 10 and the base 11 can be achieved.

[0076] In one embodiment, as shown in Figure 4 The middle part of the side surface of the jig 10 is provided with a narrow tapered slope structure 105, so that the front end and the rear end of the jig 10 form a stepped cross-section structure at the position of the narrow tapered slope structure 105.

[0077] Specifically, by using the above structure, when the jig 10 is inserted into the base 11, the part of the jig 10 inserted first is more easily inserted into the base 11, and the part inserted later can form a clamping effect of interference fit with the base 11, so that the installation of the jig 10 is more stable.

[0078] The modular wire harness detection jig assembly provided by the embodiment is applied to the field of wire harness detection, and can enable the host of the wire harness detection device to be in communication with the jig in circuit and / or air circuit through the base, realize the matching connection of the electrical structure of the host and the jig, and has the advantages of automatic completion of the matching connection process by only one insertion action of the user, simple and convenient operation of the user, short time consumption, high efficiency, and low error probability. Meanwhile, the function of replacing different jigs through the plugging and unplugging disassembly mode is realized, the disassembly is convenient and fast, the circuit and / or air circuit connection is stable, and this is favorable for quickly building a detection environment during detection of different wire harnesses, thereby improving the convenience of wire harness detection.
