Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness connector technology, and more particularly to a wiring harness connector latch position detector. Background Technology

[0002] Automotive wiring harness connectors are crucial components in automobiles, primarily used to connect wiring harnesses to ensure proper current transmission and the safe and reliable operation of the vehicle's electrical systems. Typical automotive wiring harness connectors include male and female connectors, each containing male and female terminals. During use, the male connector is inserted into the female connector, ensuring the male and female terminals align to achieve a proper wiring harness connection.

[0003] In existing technologies, female connectors are generally secondary locking connectors. During normal installation, both the primary lock 21C and the secondary lock 22 must be in the unlocked state. When locking, the male connector 1 passes under the primary lock 21C. As the male connector 1 gradually inserts into the secondary locking connector 2, the beveled boss 11 on the male connector 1 gradually pushes up the primary lock 21C. Finally, the boss 11 engages with the lock hole of the primary lock 21C, and simultaneously, the primary lock 21C returns to its original position, completing the locking. Then, the secondary lock 22 is pushed forward until the limit stop 21A contacts the rear stop point 22D of the secondary lock notch, thus locking the secondary lock 22.

[0004] However, during the assembly of automotive wiring harnesses and subsequent storage, transportation, and material handling, it is difficult to avoid the secondary lock 22 being locked due to collisions, accidental activation, or other reasons. Because the distance between the front and rear stops of the secondary lock is very small, it is difficult to distinguish the state of the secondary lock 22 with the naked eye. If a secondary lock connector 2 with the secondary lock 22 locked is mistakenly installed, the primary lock 21C, having been pressed down by the secondary lock 22, will experience significant bending deflection. When the male connector 1 is inserted into the secondary lock connector 2, the primary lock 21C can easily be broken by the male connector 1, resulting in the entire automotive wiring harness being scrapped and causing substantial economic losses. Summary of the Invention

[0005] The purpose of this invention is to provide a wire harness connector latch position checker that can solve the technical problem of visually inspecting and adjusting the locking state of secondary locking connectors.

[0006] To achieve the above objectives, the present invention provides a wire harness connector latch position detector, characterized in that: it includes a body, and inspection feet and adjustment feet respectively disposed at the lower end of the body, with a gap between the inspection feet and the adjustment feet; the end of the inspection feet is provided with an inspection block, and the end of the adjustment feet is provided with an adjustment block, the thickness of the inspection block being greater than the thickness of the adjustment block.

[0007] As a preferred embodiment, the thickness of the inspection block is greater than the gap between the tail lever of the secondary lock and the connector housing when the secondary lock is in the locked state, and less than the gap between the tail lever of the secondary lock and the connector housing when the secondary lock is in the unlocked state; the thickness of the adjustment block is less than the gap between the tail lever of the secondary lock and the connector housing when the secondary lock is in the locked state.

[0008] As a preferred embodiment, the inspection block has recesses on the surface parallel to the front and back of the main body, and the recesses are coated with bright pigments that are not easy to fade.

[0009] As a preferred embodiment, the thickness of the adjustment block increases sequentially from bottom to top along the height direction of the adjustment foot, forming a wedge-shaped guide structure.

[0010] As a preferred embodiment, the body is circular, with a circular groove in the middle, and a spiral pattern inside the circular groove.

[0011] As a preferred embodiment, both sides of the body are provided with circular grooves and spiral patterns.

[0012] As a preferred embodiment, the system also includes a lifting lug located at the upper end of the main body, with a lifting hole in the middle of the lug.

[0013] As a preferred embodiment, the line connecting the center of the lifting hole and the center of gravity of the adjustment device is perpendicular to the bottom plane of the inspection block.

[0014] As a preferred embodiment, the side of the body is provided with vertical stripes perpendicular to the circumference.

[0015] The beneficial effects of this invention are:

[0016] Using the wiring harness connector latch position checker of this invention, the operator can quickly pinch the checker to inspect each secondary latch connector during automotive wiring harness assembly. When the secondary latch is found to be in the locked state, the operator can flexibly switch the inspection foot to the adjustment foot and engage it in the gap between the tail tab of the secondary latch and the connector housing. Then, by gently twisting the checker, the secondary latch can be adjusted to the unlocked state. This invention completely solves the problem of the primary latch being broken by the male connector due to misalignment of the secondary latch, and also greatly reduces the operator's labor intensity. This technical solution is ingenious and reliable, with very low implementation cost, and perfectly solves the problem of automotive wiring harness scrapping caused by secondary latch connector assembly breakage, improving efficiency while recovering economic losses. Therefore, this invention can solve the technical problem of visually inspecting and adjusting the locking state of secondary latch connectors. Attached Figure Description

[0028] To make the technical problems solved by this invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of this invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining this invention and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this invention are shown in the accompanying drawings, not all of them.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0031] like Figures 1 to 5 As shown, this invention relates to a wire harness connector latch position checker, comprising a handle 31, a check foot 32, an adjustment foot 33, and a lifting lug 34. Specifically, it includes a main body, with the check foot 32 and the adjustment foot 33 respectively disposed at the lower end of the main body, a gap being left between the check foot 32 and the adjustment foot 33; the end of the check foot 32 is provided with a check block 32B, and the end of the adjustment foot 33 is provided with an adjustment block 33A, the thickness of the check block 32B being greater than the thickness of the adjustment block 33A. In this embodiment, the thickness of the check block 32B is greater than the gap between the secondary lock tail lever 22A and the connector housing 21 when the secondary lock 22 is in the locked state, and smaller than the gap between the secondary lock tail lever 22A and the connector housing 21 when the secondary lock 22 is in the unlocked state; the thickness of the adjustment block 33A is smaller than the gap between the secondary lock tail lever 22A and the connector housing 21 when the secondary lock 22 is in the locked state.

[0032] A rectangular recess 32A is formed on the surface of the inspection block 32B that is parallel to the front and back surfaces of the main body. The recess 32A is coated with a bright pigment that is not easy to fade. The thickness of the adjustment block 33A increases from bottom to top along the height direction of the adjustment foot 33, forming a wedge-shaped guide structure.

[0033] The main body is circular, with a circular groove 31A in the center, and the interior of the circular groove 31A has a spiral pattern. Circular grooves 31A and spiral patterns are also present on both sides of the main body. Vertical stripes 31C perpendicular to the circumference of the main body are provided on the side to increase friction on the operator's hands. A lifting lug 34 is provided at the upper end of the main body, with a lifting hole 34A in the center of the lug 34. The line connecting the center of the lifting hole 34A and the center of gravity of the inspector is perpendicular to the bottom plane of the inspection block 32B.

[0034] like Figure 6 , Figure 7 As shown, the locking part of the secondary lock connector 2 consists of a primary lock 21C integrated on the housing 21 and a secondary lock 22 installed in the housing slide rail 21B. The primary lock 21C is fixed, while the secondary lock 22 can slide back and forth along the housing slide rail 21B. Each side of the housing slide rail 21B has a symmetrical limiting step 21A, and each side of the secondary lock has a symmetrical "[" shaped notch. During assembly, the secondary lock 22 is slid into the housing slide rail 21B. When the limiting step 21A engages with the secondary lock notch, the working stroke of the secondary lock 22 is formed. When the limiting step 21A contacts the front stop point 22C of the secondary lock notch, the secondary lock 22 is in the unlocked state. When the limiting step 21A contacts the rear stop point 22D of the secondary lock notch, the secondary lock 22 is in the locked state.

[0035] During normal installation, both the primary lock 21C and the secondary lock 22 must be in the unlocked state. The male connector 1 can pass under the primary lock 21C. As the male connector 1 gradually inserts into the secondary lock connector 2, the beveled boss 11 on the male connector 1 gradually lifts the primary lock 21C, until the boss 11 finally engages with the lock hole of the primary lock 21C. At the same time, the primary lock 21C returns to its original position, completing the locking. Then, the secondary lock 22 is pushed forward until the limit stop 21A contacts the rear stop point 22D of the secondary lock notch, locking the secondary lock 22. During this process, the pressure head 22B at the front of the secondary lock presses down on the primary lock 21C, causing it to bend downwards. In the locked state, the lock hole of the primary lock 21C prevents the male connector boss 11 from retracting, while the male connector boss 11 prevents the secondary lock 22 from retracting. This type of secondary locking connector 2 can effectively prevent the male connector plug boss 11 from opening the primary lock 21C under accidental pull-out force or vibration, causing the connector to loosen. It is often used to match actuators such as electromagnetic valves that vibrate strongly.

[0036] like Figure 4 , Figure 5As shown, the material of the adjustment device 3 can be stainless steel, aluminum alloy, or other common metals or engineering plastics. The adjustment device 3 consists of a handle 31, an inspection foot 32, an adjustment foot 33, and a lug 34. Circular grooves 31A are symmetrically arranged on both sides of the handle 31 at the center position, facilitating gripping with the thumb and middle finger. The bottom surface of the circular grooves 31A also features spiral grooves 31B to increase friction. The outer cylindrical surface of the handle between the lug 34 and the inspection foot 32, and between the lug 34 and the adjustment foot 33, is provided with evenly spaced vertical stripes 31C. When the operator grips the adjustment device 3 with their thumb and middle finger, they can quickly switch between the inspection foot 32 and the adjustment foot 33 by moving the handle 31 with their index finger.

[0037] The inspection foot 32 is located on the outer cylindrical surface of the handle 31. The thickness of the inspection block is consistent from top to bottom. The thickness of the inspection foot 32 is slightly smaller than the gap between the secondary lock tail lever 22A and the connector housing 21 when the secondary lock 22 is in the unlocked state. Its width is smaller than the width of the secondary lock tail lever 22A, and its height is greater than the height of the secondary lock tail lever 22A. Rectangular recesses 32A are symmetrically provided on both sides of the inspection foot 32. The bottom of the recesses is coated with a bright, non-fading paint for easy observation by the operator. The position of the rectangular recesses 32A is designed to ensure that after the inspection foot 32 is inserted into the gap between the secondary lock tail lever 22A and the connector housing 21, it can be covered by the secondary lock tail lever 22A.

[0038] Adjusting foot 33 is located on the outer cylindrical surface of handle 31, next to inspection foot 32. The thickness of adjusting foot 33 is slightly less than the gap between the tail lever 22A of the secondary lock 22 and the connector housing 21 when the secondary lock 22 is in the locked state, and it gradually thickens from bottom to top, forming a wedge-shaped guide function. The width of adjusting foot 33 is less than the width of the tail lever 22A of the secondary lock, but its height is greater than the height of the tail lever 22A of the secondary lock 22. Adjusting foot 33 and inspection foot 32 form a "V" shape, and the angle between them should ensure that when either foot is engaged, the other foot does not interfere with the secondary lock structure connector 2. At the same time, the angle between adjusting foot 33 and inspection foot 32 should not be too large to prevent excessive hand movement when switching between them. In this embodiment, a 45° angle between adjusting foot 33 and inspection foot 32 is recommended.

[0039] The lifting lug 34 is located on the outer cylindrical surface of the handle 31, opposite the inspection foot 32. Specifically, its position should ensure that the line connecting the lifting hole 34A of the lifting lug 34 and the center of gravity 35 of the adjustment device 3 is perpendicular to the bottom plane of the inspection block 32B. Figure 5 As shown. With this design, the suspended inspection foot 32 can hang vertically downwards. After the operator picks up the inspection device 3, it can be used directly to inspect the secondary locking connector 2 without adjusting its posture, thus improving the accuracy and efficiency of the inspection.

[0040] At the automotive wiring harness assembly station containing the secondary lock structure connector 2, the tester 3 is suspended at an easily accessible position and height using a lanyard. Before assembling each secondary lock structure connector 2, the tester 3's test foot 32 is used to check the gap between the secondary lock tail lever 22A and the connector housing 21. If the color mark within the rectangular recess 32A is obscured by the secondary lock tail lever 22A, it indicates that the tester 3's test foot 32 can engage, the connector secondary lock 22 is in the unlocked state, and assembly can proceed directly. If the color mark within the rectangular recess 32A is not obscured, it indicates that the tester 3's test foot 32 cannot engage, the connector secondary lock 22 is in the locked state. When the secondary lock 22 is in the locked state, the operator can use the index finger to move the handle 31 or twist the wrist to switch the adjusting foot 33 to the appropriate position, then insert the secondary lock tail piece 22A into the gap between the connector housing 21, and finally gently twist the adjustment device 3 to adjust the secondary lock 22 to the unlocked state before assembly.

[0041] After adopting the above technical solution, the operator can quickly pinch the tester 3 to check each secondary lock connector 2 during automotive wiring harness assembly. When the secondary lock 22 is found to be in the locked state, the operator can flexibly switch the inspection foot 32 to the adjustment foot 33 and engage it in the gap between the secondary lock tail lever 22A and the connector housing 21. Then, gently twist the tester 3 to make the adjustment foot 33 move the secondary lock tail lever 22A in the unlocking direction, increasing the gap between the secondary lock tail lever 22A and the connector housing 21, thus adjusting the secondary lock 22 to the unlocked state. This invention completely solves the problem of the primary lock 21C being broken by the male connector 1 due to the misalignment of the secondary lock 22, and also greatly reduces the operator's labor intensity. This technical solution is ingenious and reliable, with very low implementation cost, perfectly solving the problem of automotive wiring harness scrapping caused by secondary lock connector assembly breakage, improving efficiency while recovering economic losses.

[0042] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
