Description

Technical Field

[0001] This invention relates to the field of automotive connector technology, and more specifically, to an anti-loosening connector holder for automotive wiring harnesses. Background Technology

[0002] In automotive electrical systems, wiring harness connectors are interfaces that enable reliable signal and power transmission between various electronic and electrical components. They consist of plug-type connectors and socket-type connectors, and the stability of their connection is directly related to the normal operation and safety of the entire vehicle. Existing automotive wiring harness connectors use a locking mechanism formed by protrusions and elastic claws. However, during the manual insertion of the plug-type connector into the socket-type connector, errors can occur, resulting in an "incomplete connection" between the socket-type connector and the plug-type connector. This can cause the socket-type connector to loosen due to vibration during vehicle operation, leading to an interruption of signal transmission between the socket-type connector and the plug-type connector.

[0003] In the existing technology, there is a typical and frequently occurring failure scenario: when a plug-type connector is inserted into a socket-type connector, although the two bodies are in a parallel mating state, due to the limitation of the installation position, the wire harness leading out from the tail of the plug-type connector is forced to form a sharp bend or angle at the exit. Due to the rebound tendency of the wire harness itself, a continuous lateral pulling force will be generated at this angle. If the initial snap-fit ​​connection between the socket-type connector and the plug-type connector is "loosely inserted", or if the pre-tightening force of the snap-fit ​​itself is insufficient and there is a weak link, under the action of this continuous pulling force, the plug-type connector will be gradually pulled away from the socket-type connector, eventually leading to the interruption of electrical connection.

[0004] Furthermore, when fixing socket-type connectors, mounting holes are usually symmetrically opened on the connector housing, and screws are used to directly fix it to the car body. When tightening the screws, human error may cause deviations in the screw installation position or inconsistent tightening torque, which introduces additional assembly stress into the connector housing. Under the vibration and impact of long-term vehicle driving, the connector housing may crack, and even damage the internal wiring harness. In addition, when installing and fixing socket-type connectors, if there is spatial interference in the actual installation environment, the only way to adjust is to forcibly twist the wiring harness or add brackets. This will exacerbate the wiring harness bending problem, artificially introduce more bending moment, and thus reduce the connection stability between the socket-type connector and the plug-type connector.

[0005] To solve the above problems, the inventors proposed an anti-loosening connector holder for automotive wiring harnesses. Summary of the Invention

[0006] To solve the above-mentioned technical problems, an anti-loosening connector holder for automotive wiring harnesses is provided. This technical solution solves the problems mentioned in the background art. To achieve the above objectives, the present invention can be implemented using the following technical solutions: This invention provides an anti-loosening connector fixing base for automotive wiring harnesses, including a fixing base, a socket-type connector and a plug-type connector. The socket-type connector is provided with a protrusion, and the plug-type connector is provided with an elastic claw. The socket-type connector and the plug-type connector are detachably connected by a snap-fit. The outer wall of the plug-type connector is symmetrically fixed with two side plates. The fixed base is equipped with an anti-detachment component, which includes an adjusting plate rotatably connected to the fixed base. The adjusting plate has a placement groove, and a protective shell is fixedly connected to the surface of the adjusting plate. The outer wall of the protective shell has four through slots equidistantly arranged in an annular pattern. Multiple bases are fixedly connected equidistantly in an annular pattern inside the protective shell. Each base is rotatably connected to a support plate, and a spring is fixedly connected between each support plate and the protective shell. Two annular sliding plates are symmetrically slidably connected to the outer wall of the protective shell, and a locking plate is fixedly connected to each annular sliding plate. Two extension platforms are symmetrically fixedly connected to the outer wall of the protective shell, and a knob rod is threaded into each extension platform. A ball head is fixedly connected to the end of each knob rod.

[0007] Preferably, the fixing base and the adjusting plate are both square, the placement slot is slidably adapted to the socket-type connector, the outer wall of the protective shell is provided with an operating hole, and each of the support plates is set in an inclined shape.

[0008] Preferably, the two annular sliding plates are engaged, and each of the locking plates is slidably adapted to a nearby through groove.

[0009] Preferably, the adjustment plate is provided with a quick-release assembly, which includes hollow columns. Four hollow columns are symmetrically arranged. Each hollow column has a combination hole at its end. A combination rod is slidably connected to the inner cavity of each hollow column. A pull plate and a beveled cylinder are fixedly connected to the end of each combination rod. A second spring is fixedly connected to the inner cavity of each hollow column. Each second spring abuts against the adjacent combination rod. A baffle is fixedly connected to the outer wall of each hollow column.

[0010] Preferably, the quick-release assembly further includes four bosses symmetrically arranged, each boss being fixedly connected to a socket-type connector, each boss having a limiting hole on its surface, and each limiting hole being adapted to a beveled cylinder.

[0011] Preferably, each of the combined holes is connected to the inner cavity of a nearby hollow column, each of the combined rods is composed of a rectangular block portion and a T-shaped column portion, and each of the combined rods is slidably adapted to the combined hole.

[0012] Preferably, the adjusting plate is provided with an adjusting assembly, which includes a rotary control rod and a transmission rod. Both the rotary control rod and the transmission rod are fixedly connected to the adjusting plate. A sleeve is fixedly connected to the outer wall of the fixed base. An elastic sleeve is fixedly connected inside the sleeve. A pressure ring is slidably connected to the inner cavity of the sleeve. An L-shaped plate is fixedly connected to the end of the pressure ring. A threaded seat is fixedly connected to the end of the sleeve. Four sets of wire harness frames are symmetrically fixedly connected to the fixed base. Each set of wire harness frames consists of multiple wire harness frames.

[0013] Preferably, both the rotary control rod and the transmission rod are rotatably connected to the fixed base, and the L-shaped plate is detachably connected to the threaded seat by bolts.

[0014] Preferably, the outer surface of the transmission rod is provided with grooves, the elastic sleeve is tapered, and the elastic sleeve has four straight grooves equidistantly spaced in an axial ring.

[0015] As described above, the advantages of this invention are: The anti-disengagement component in this device uses a rotary knob to push a locking plate with a ball head, thereby applying a thrust to the side plate and achieving a pressure-locking effect. If there is a loose connection between the socket-type connector and the plug-type connector, this thrust will push the side plate and the plug-type connector to a fully engaged position. This solves the problem in the prior art where human error can cause the socket-type connector and the plug-type connector to not be tightly inserted. If the socket-type connector and the plug-type connector are already tightly inserted, this thrust is converted into a reinforcing force for the locked state. Even if the latch that secures the socket-type connector and the plug-type connector fails in extreme cases, the locking plate can still provide effective secondary blocking to prevent the socket-type connector and the plug-type connector from separating. This improves the reliability of automotive wiring harness connector connections.

[0016] The anti-disengagement component in this device, through a ring-shaped support plate, works in conjunction with a spring. When the wire harness at the end of the plug-type connector bends, the resulting bending moment acts directly on the support plate and is converted into compression of the spring. The spring's rebound force generates a torque opposite to the bending direction, thus providing buffer support. This solves the problem in existing technologies where bending of the wire harness within the plug-type connector due to its installation position generates bending moment, and the resulting pulling force pulls the plug-type connector, causing it to loosen from the socket-type connector. Furthermore, in the vibration environment of long-term vehicle operation, the spring can effectively absorb high-frequency vibrations transmitted by the wire harness, thereby improving the durability of the automotive wire harness connector connection.

[0017] The quick-release assembly in this device uses the fit between the beveled cylinder and the limiting hole to quickly fix the socket-type connector onto the adjustment plate, making it an integral part of the adjustment plate. Furthermore, when using screws to fix the connector to the car body, the screws apply pressure to the mounting base instead of applying pressure to the connector housing. This avoids introducing additional assembly stress during installation and solves the problem in existing technologies where directly fixing the connector to the car body with screws easily introduces additional stress into the connector housing, causing cracks in the housing under the vibration of long-term vehicle operation and resulting in damage to the internal connecting wires. This improves the stability of the automotive wiring harness connector connection.

[0018] The adjustment component in this device, by setting the mounting base and adjustment plate as squares and setting multiple wire harness frames in the four directions of the mounting base, allows for "horizontal installation" or "vertical installation" of the mounting base according to the installation environment and wiring requirements, thus better managing the wiring harness routing. At the same time, the socket-type connector can be adjusted in orientation angle to adapt to different installation environments, solving the problem that the socket-type connector cannot adjust the orientation angle in the prior art, thereby improving the flexibility of automotive wiring harness connector connections.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The embodiments provided by the present invention will be described in detail below: An anti-loosening connector holder for automotive wiring harnesses, such as Figure 1 As shown, it includes a fixed base 1, a socket-type connector 2, and a plug-type connector 3. The socket-type connector 2 is provided with a protrusion, and the plug-type connector 3 is provided with a flexible claw. The socket-type connector 2 and the plug-type connector 3 are detachably connected by a snap-fit ​​formed by the protrusion and the flexible claw. The openings of the socket-type connector 2 and the plug-type connector 3 away from the fixed base 1 are both connected to wire harnesses. The core wires of the wire harnesses are crimped and fixed to the conductive terminals inside the socket-type connector 2 and the plug-type connector 3 to realize bidirectional transmission of electrical signals and electrical energy. The snap-fit ​​connection of the socket-type connector 2 and the plug-type connector 3 and the connection of the internal wire harnesses are existing technologies and will not be described in detail here. Two side plates 31 are symmetrically fixedly connected to the outer side wall of the plug-type connector 3. like Figures 2 to 7 As shown, the fixed base 1 is equipped with an anti-detachment component, which includes an adjusting plate 41 rotatably connected to the fixed base 1. The surface of the adjusting plate 41 has a placement groove 42. A protective shell 43 is fixedly connected to the outer wall of the adjusting plate 41. Four through slots 44 are equidistantly formed on the outer ring surface of the protective shell 43. Multiple bases 45 are equidistantly fixedly connected to the inner ring surface of the protective shell 43. A support plate 46 is rotatably connected to each base 45. A spring 47 is fixedly connected between each support plate 46 and the protective shell 43. The spring 47 is located on the base 45. On the side away from the through groove 44, two annular sliding plates 48 are symmetrically slidably connected to the outer ring of the protective shell 43. Each annular sliding plate 48 has a retaining plate 49 fixedly connected to its inner concave surface. Two extension platforms 410 are symmetrically fixedly connected to the outer ring of the protective shell 43. Each extension platform 410 has a knob rod 411 threadedly connected inside. Part of the knob rod 411 extends out of the extension platform 410. Each knob rod 411 has a ball head 412 fixedly connected to the end near the through groove 44. Each ball head 412 abuts against the outer wall of the adjacent extension platform 410.

[0023] Furthermore, such as Figure 2 and Figure 7 As shown, the fixed base 1 and the adjusting plate 41 are both square. The placement groove 42 is slidably adapted to the socket type connector 2. The outer ring surface of the protective shell 43 is provided with an operating hole. When the socket type connector 2 and the plug type connector 3 are snapped together, the operating hole is located directly above the protrusion and the elastic claw, which makes it easy for the operator to pull the elastic claw to separate the socket type connector 2 and the plug type connector 3. Each support plate 46 is set to be inclined.

[0024] Furthermore, such as Figure 5 and Figure 6 As shown, the two annular sliding plates 48 are interlocked, and each plate 49 is slidably adapted to the adjacent through groove 44.

[0025] Furthermore, such as Figures 9 to 11As shown, the adjustment plate 41 is equipped with a quick-release assembly, which includes four hollow columns 51. The four hollow columns 51 are symmetrically arranged in pairs. All four hollow columns 51 are located inside the fixed base 1. Each hollow column 51 has a combination hole 52 on its end face. Each hollow column 51 has a vertically sliding connection to a combination rod 53 in its inner cavity. Each combination rod 53 has a pull plate 54 and a beveled cylinder 55 fixedly connected to its end face. The pull plate 54 is located at the end of the hollow column 51 near the combination hole 52, and the beveled cylinder 55 is located at the end of the hollow column 51 away from the combination hole 52. Each hollow column 51 has a spring 56 fixedly connected to the end of its inner cavity near the pull plate 54. The end of each spring 56 away from the pull plate 54 abuts against the adjacent combination rod 53. Each hollow column 51 has a baffle 57 fixedly connected to the side of its outer wall near the placement groove 42. The side of the beveled cylinder 55 away from the baffle 57 is set as a slope.

[0026] Furthermore, such as Figure 8 and Figure 9 As shown, the quick-release assembly also includes bosses 58, four of which are symmetrically arranged. The four bosses 58 are arranged in pairs, with one set of bosses 58 located on the upper surface of the socket connector 2 and the other set of bosses 58 located on the bottom surface of the socket connector 2. The four bosses 58 correspond to the four hollow pillars 51. The baffle 57 is used to block the bosses 58. When the bosses 58 abut against the baffle 57, the socket connector 2 will be quickly fixed at that position. Each boss 58 is fixedly connected to the outer wall of the socket connector 2. Each boss 58 has a limiting hole 59 on the side away from the socket connector 2. Each limiting hole 59 is adapted to the beveled cylinder 55.

[0027] Furthermore, such as Figure 10 As shown, each combined hole 52 is connected to the inner cavity of the adjacent cavity column 51, and each combined rod 53 is composed of a rectangular block and a T-shaped column. The rectangular block is located inside the combined hole 52 and partially inside the cavity column 51, while the T-shaped block is entirely located inside the cavity column 51. Each combined rod 53 is slidably adapted to the combined hole 52.

[0028] Furthermore, such as Figure 9 , Figure 12 and Figure 13As shown, an adjustment assembly is provided on the adjustment plate 41. The adjustment assembly includes a rotary control rod 61 and a transmission rod 62. Both the rotary control rod 61 and the transmission rod 62 are fixedly connected to the adjustment plate 41. The rotary control rod 61 and the transmission rod 62 are located on the same axis. A portion of the transmission rod 62 extends out of the fixed seat 1. A sleeve 63 is fixedly connected to the outer wall of the fixed seat 1. An elastic sleeve 64 is fixedly connected to the end of the inner cavity of the sleeve 63 away from the fixed seat 1. The elastic sleeve 64 is located outside the transmission rod 62. A pressure ring 65 is horizontally slidably connected to the inner cavity of the sleeve 63. An L-shaped plate 66 is fixedly connected to the end of the pressure ring 65 away from the fixed seat 1. A portion of the L-shaped plate 66 extends out of the sleeve 63. A threaded seat 67 is fixedly connected to the end of the sleeve 63 away from the fixed seat 1. Four sets of wire harness frames 68 are symmetrically fixedly connected to the fixed seat 1. Each set of wire harness frames 68 is composed of multiple wire harness frames 68.

[0029] Furthermore, such as Figure 12 As shown, both the rotary control rod 61 and the transmission rod 62 are rotatably connected to the fixed base 1. By rotating the rotary control rod 61, the adjusting plate 41 can be rotated around the transmission rod 62 as the axis. The L-shaped plate 66 is detachably connected to the threaded seat 67 by bolts.

[0030] Furthermore, such as Figure 13 As shown, the outer ring surface of the transmission rod 62 that protrudes from the fixed seat 1 is provided with grooves. The elastic sleeve 64 is tapered and has four straight grooves equidistantly spaced in the axial ring. The elastic sleeve 64 is divided into four elastic plates by the four straight grooves. The grooves are used to increase friction. When the inner ring surface of the elastic sleeve 64 is in close contact with the outer ring surface of the transmission rod 62, the transmission rod 62 cannot rotate.

[0031] During work: This device can quickly fix the socket-type connector 2 and adjust the orientation angle of the socket-type connector 2. The detailed steps are as follows: Since the other ends of the wire harnesses connected to the ends of the socket-type connector 2 and the plug-type connector 3 are connected to different electrical components inside the car body, and since the different electrical components are located in different positions, the wire harnesses may be led out from the electrical components in four directions: "up, down, left, and right" and connected to the end of the socket-type connector 2 or the end of the plug-type connector 3.

[0032] Since the routing of the wire harnesses connected to the ends of the socket-type connector 2 and the plug-type connector 3 is determined according to the actual installation position of the connected electrical components in the vehicle body, the socket-type connector 2 and the plug-type connector 3 may not be located on the same axis. The staff selects the installation direction of the mounting base 1 based on the location of the plug-type connector 3, i.e., the horizontal installation direction, such as... Figure 1As shown, or by rotating 90 degrees vertically, if the plug-type connector 3 is located diagonally above or below the socket-type connector 2, the mounting base 1 can be installed horizontally, such as... Figure 2 As shown, the adjusting plate 41 can swing up and down around its rotation axis. When the plug-type connector 3 is located on the oblique side of the socket-type connector 2, the fixing base 1 can be installed in a vertical direction. The adjusting plate 41 can swing left and right around its rotation axis. Since both the fixing base 1 and the adjusting plate 41 are set as squares, the plane installation area occupied by the fixing base 1 on the car body remains unchanged whether the horizontal or vertical installation method is adopted. There will be no additional space requirement due to the change of installation direction. In this way, it can adapt to different installation directions. At the same time, a set of wire harness frames 68 are provided on the four directions of the surface of the fixing base 1, so as to adapt to different wire harness routing directions at the end of the socket-type connector 2.

[0033] The following explanation assumes that the mounting bracket 1 is installed in a horizontal direction: After determining the installation direction, insert the socket-type connector 2 into the placement slot 42. During the movement of the socket-type connector 2, the four protrusions 58 on the surface of the socket-type connector 2 simultaneously contact the inclined surfaces of the adjacent obliquely cut cylinders 55 and push the obliquely cut cylinders 55, causing the obliquely cut cylinders 55 to move vertically along the inner cavity of the hollow column 51 towards the side closer to the second spring 56, and compressing the second spring 56, so that the second spring 56 is gradually compressed until the obliquely cut cylinders 55 are completely located in the inner cavity of the hollow column 51. At this time, the surface of the protrusions 58 provides limiting support for the obliquely cut cylinders 55, and the obliquely cut cylinders 55 stop moving vertically. As the socket-type connector 2 continues to move, when the boss 58 abuts against the baffle 57, the limiting hole 59 is located directly below the beveled cylinder 55. The beveled cylinder 55 is no longer limited by the boss 58, and the second spring 56 returns to its original position, causing the beveled cylinder 55 to move vertically away from the second spring 56 and insert into the limiting hole 59. The beveled cylinder 55 stops moving when it abuts against the inner end face of the limiting hole 59. When all four beveled cylinders 55 are inserted into the corresponding limiting holes 59, the socket-type connector 2 is quickly fixed.

[0034] After the socket connector 2 is quickly fixed, the operator rotates the control lever 61 as needed, thereby adjusting the orientation angle of the socket connector 2 via the adjustment plate 41. Once the angle is determined, the L-shaped plate 66 is pushed, causing the pressure ring 65 to move towards the side closer to the transmission rod 62. During the horizontal movement of the pressure ring 65, the inner ring surface of the pressure ring 65 contacts and presses the outer conical surface of the elastic sleeve 64, causing the horizontal movement of the pressure ring 65 to be converted into radial compression of the elastic sleeve 64. The compression force causes the multiple elastic plates on the elastic sleeve 64, which are divided by straight grooves, to contract. As the L-shaped plate 66 moves to a point where it contacts and fits against the threaded seat 67, a bolt is screwed into the threaded seat 67. At this point, the retracted portion of the elastic sleeve 64 is tightly fitted against the outer surface of the transmission rod 62. The bolt is then tightened, keeping the pressure ring 65 stationary in its current position. Because the pressure ring 65 is fixed in a stationary state, the retracted portion of the elastic sleeve 64 continues to clamp the transmission rod 62, preventing it from rotating freely. This locks the adjusting plate 41, further fixing the orientation angle of the socket-type connector 2.

[0035] Then, the wire harness at the end of the socket connector 2 is fixed in a certain group of wire harness frames 68 according to its wire harness direction, and the fixing seat 1 is fixed to the car body with screws.

[0036] In the above process, the adjustment component in this device, by setting the fixed base 1 and the adjustment plate 41 as squares and setting multiple wire harness frames 68 in the four directions of the fixed base 1, can select the fixed base 1 for "horizontal installation" or "vertical installation" according to the installation environment and wiring requirements, so as to better manage the wire harness routing. At the same time, the socket-type connector 2 can be adjusted in orientation angle to adapt to different installation environments, thus solving the problem that the socket-type connector 2 cannot adjust the orientation angle in the prior art, thereby improving the flexibility of automotive wire harness connector connection.

[0037] In the above process, the quick-release component in this device, through the cooperation between the oblique cylinder 55 and the limiting hole 59, quickly fixes the socket-type connector 2 onto the adjusting plate 41, making it an integral part of the adjusting plate 41. When using screws to fix it to the car body, the screws apply pressure to the fixing seat 1 instead of applying pressure to the housing of the socket-type connector 2. This avoids introducing additional assembly stress during installation and solves the problem in the prior art where directly using screws to fix the socket-type connector 2 to the car body easily introduces additional stress into the housing of the socket-type connector 2, causing cracks in the housing of the socket-type connector 2 under the vibration environment of long-term car driving, resulting in damage to the internal connecting wires. In this way, the stability of the automotive wiring harness connector connection is improved.

[0038] This device can prevent the socket-type connector 2 and the plug-type connector 3 from coming loose after they are snapped together. The detailed steps are as follows: After securing the mounting bracket 1 to the car body, separate the two annular sliding plates 48, then move the plug-type connector 3 inside the protective shell 43, insert the plug-type connector 3 into the socket-type connector 2, and form a snap-fit ​​connection with the protrusion through the elastic claw. This snap-fit ​​connection is existing technology. At this point, both side plates 31 are located at the position of the through groove 44. Figure 7 As shown, after the snap-fit ​​connection between the plug-type connector 3 and the socket-type connector 2 is completed, the two annular sliding plates 48 are engaged and positioned in the initial position. Then, the two knobs 411 are rotated clockwise, causing the knobs 411 to move the ball head 412 towards the side closer to the adjustment plate 41. During this process, the ball head 412 pushes the two annular sliding plates 48, causing the two locking plates 49 to move. The locking plates 49 move away from the extension platform 410. When the two locking plates 49 move and abut against the two adjacent side plates 31, and the ball head 412 can no longer be moved by rotating the knobs 411, the socket-type connector 2 and the plug-type connector 3 are completely locked together.

[0039] If, during the movement of the locking plate 49, the socket-type connector 2 and the plug-type connector 3 are not properly locked due to human error, the movement and contact of the locking plate 49 can push the side plate 31, thereby fully locking the socket-type connector 2 and the plug-type connector 3. The locking plate 49 also applies an anti-loosening measure to the contact of the side plate 31. If the socket-type connector 2 and the plug-type connector 3 are already fully locked, the contact of the locking plate 49 can directly apply an anti-loosening measure to the side plate 31, forming a double insurance with the snap-fit ​​connection between the socket-type connector 2 and the plug-type connector 3.

[0040] In the above process, the anti-disengagement component in this device, by rotating the knob rod 411, causes the ball head 412 to push the locking plate 49, thereby applying a pushing force to the side plate 31 to achieve the effect of pressure locking. If there is a loose insertion between the socket type connector 2 and the plug type connector 3, this pushing force will push the side plate 31 and the plug type connector 3 to the fully inserted position, solving the problem in the prior art where human error causes the socket type connector 2 and the plug type connector 3 to not be tightly inserted. If the socket type connector 2 and the plug type connector 3 are already tightly inserted, this pushing force is converted into a reinforcing force for the locked state. Even if the buckle that fixes the socket type connector 2 and the plug type connector 3 fails in extreme cases, the locking plate 49 can still provide an effective secondary barrier to prevent the socket type connector 2 and the plug type connector 3 from separating, thus improving the reliability of the automotive wiring harness connector connection.

[0041] This device can support the wire harness that has bent at the tail of the plug-type connector 3. The detailed steps are as follows: After the snap-fit ​​connection between the socket connector 2 and the plug connector 3 is completed, the socket connector 2 and the plug connector 3 are located on the same axis, such as... Figure 7 As shown, due to the installation location, the wire harness at the end of the plug connector 3 may be bent, resulting in a bend in the wire harness. This situation will continuously generate a bending moment that makes the wire harness try to return to its original shape, that is, to return to a horizontal state. This bending moment will form a rebound force that acts directly on the plug connector 3, forming a pulling force that attempts to pull the plug connector 3 out of the socket connector 2. When the wire harness at the tail of the plug-type connector 3 is forced to bend due to its arrangement, it will press against the support plate 46 inside the protective shell 43, which is in contact with it. This applies pressure to the support plate 46, causing it to rotate forward about the rotatable connection point with the base 45. Figure 7 As shown, during this process, the rotation of the support plate 46 will compress the spring 47, causing the spring 47 to be in a compressed state. The rebound force generated by the spring 47 will act in the opposite direction on the wire harness, forming a torque opposite to the bending direction, thereby reducing the pulling force generated by the bending of the wire harness.

[0042] In the above process, the anti-disengagement component in this device, through the ring-shaped support plate 46, cooperates with the spring 47. When the wire harness at the end of the plug connector 3 bends, the bending moment generated directly acts on the support plate 46 in contact with it and is converted into compression of the spring 47. The rebound force of the spring 47 generates a torque opposite to the bending direction, thereby providing buffer support. This solves the problem in the prior art where the wire harness in the plug connector 3 bends due to the installation position, resulting in bending moment. The pulling force generated by the bending moment pulls the plug connector 3, causing the socket connector 2 and the plug connector 3 to become loose. Furthermore, in the vibration environment of long-term vehicle operation, the spring 47 can also effectively absorb the high-frequency vibration transmitted by the wire harness, thus improving the durability of the automotive wire harness connector connection.

[0043] If it is necessary to separate the socket type connector 2 and the plug type connector 3, first pull the elastic claw on the socket type connector 2 through the operating hole on the outer ring surface of the protective shell 43, so that the elastic claw separates from the protrusion on the socket type connector 2. Then pull the plug type connector 3 in a direction away from the socket type connector 2, so that the plug type connector 3 separates from the socket type connector 2. Then remove the screws fixing the fixing seat 1, so that the fixing seat 1 separates from the car body. After the fixed seat 1 is separated from the car body, the two sets of pull plates 54 can be pulled outward through the operating holes on the upper and lower parts of the protective shell 43, so that the pull plates 54 move vertically in the direction away from the spring 56. The pull plates 54 drive the combined rod 53 and the oblique cylinder 55 to move together. When the rectangular block in the combined rod 53 leaves the combined hole 52, the oblique cylinder 55 is located in the inner cavity of the hollow column 51. After rotating the pull plate 54 ninety degrees and releasing it, the combined rod 53 will limit the rectangular block, so that the oblique cylinder 55 remains in the inner cavity of the hollow column 51 and remains stationary. For the remaining three pull plates 54. Repeat the above steps. After all four oblique cylinders 55 have left the adjacent limiting holes 59, the socket-type connector 2 can be removed. Then, the bolts fixing the L-shaped plate 66 can be removed. When the bolts leave the threaded seat 67, pull the L-shaped plate 66 outward, so that the L-shaped plate 66 drives the pressure ring 65 to move together until the pressure ring 65 returns to the initial position. During this process, the multiple elastic plates on the elastic sleeve 64, which are divided by straight grooves, reset and spring back, no longer contacting the part of the transmission rod 62 with grooves. In this way, the orientation angle of the adjustment plate 41 can be readjusted for convenient use next time.

[0044] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
