Description

Technical Field

[0001] The present invention relates to the technical field of vehicle protection, and specifically relates to a protection device and method for a vehicle wiring harness connector. Background Art

[0002] A vehicle wiring harness connector is an important component for connecting automotive electrical circuits. Its function is to connect each circuit in the vehicle electrical circuit, provide a good path for current flow and electrical signal transmission, and thus realize the normal and stable operation of the circuit.

[0003] The patent with the patent publication number CN211480424U discloses a protection device for a vehicle wiring harness connector and a vehicle, which relates to the field of vehicles. The protection device for the vehicle wiring harness connector includes a first housing and a second housing made of a metal material. Four side walls and a cover plate of the first housing form a first accommodation space, and four side walls and a bottom plate of the second housing form a second accommodation space. The first accommodation space and the second accommodation space cooperate to form an installation space for installing the wiring harness connector. The protection device for the vehicle wiring harness connector provided by this patent has the advantages of simple structure, low manufacturing cost, and strong anti-interference ability.

[0004] However, there are still deficiencies in the current device: the device extends the service life of the wiring harness connector through good anti-interference ability. However, when the protective shell is installed inside the vehicle, due to the relatively small space and the complexity of the surrounding circuits and components, to a certain extent, it is easy to increase the installation difficulty of the protective shell, and at the same time, it is easy to be misaligned during installation, resulting in a decrease in the installation tightness. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a protection device and method for a vehicle wiring harness connector, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A protection device for a vehicle wiring harness connector includes a device main body. A jack is provided inside the device main body, a connection seat is arranged inside the jack of the device main body, and a wiring harness is arranged inside the connection seat;

[0007] Anti-shake devices are arranged on both the upper and lower sides of the device main body. An anti-exposure device is arranged on the periphery of the anti-shake device, and an anti-collision device is arranged on the side of the anti-exposure device away from the device main body;

[0008] The anti-shake device includes two protective shells, which are respectively arranged above and below the device body. Heat dissipation openings are provided inside both protective shells. Mounting holes are equidistantly arranged at the bottom of the upper protective shell. A number of mounting components are fixedly installed equidistantly and at the top edge of the lower protective shell. A slide rail is fixedly installed on the side of the protective shell away from the axis of the device body. A chute is provided at the top of the slide rail. A fixing component is slidably installed inside the slide rail. An arc-shaped block is fixedly installed on the side of the fixing component away from the axis of the device body. A U-shaped plate is fixedly installed on the side of the slide rail away from the axis of the device body. A number of telescopic abutting plates are fixedly installed equidistantly on the side of the U-shaped plate close to the slide rail. The outer walls of the telescopic abutting plates are all located inside the chute of the slide rail. When installing the device body into the engine room, the wire harness is connected through the connecting seat. At the same time, the upper and lower protective shells move synchronously towards the device body. And the protective shell is made of anti-magnetic material. Then the lower protective shell drives the mounting components towards the inside of the mounting holes of the upper protective shell. When the upper and lower protective shells are gathered, the mounting components are snapped into the mounting holes. At this time, the upper and lower protective shells are fixed to each other and cover the device body to complete the protection work. When it is necessary to install the protective shell into the engine room, the staff adjusts the installation orientation with the engine room by moving the fixing component inside the slide rail. When the appropriate installation orientation is determined, the fixing component is snapped into the installation location inside the engine room. Then the staff fixes the fixing component and the installation location with bolts to complete the installation work. At the same time, when the fixing component slides, it drives the arc-shaped block to move synchronously. During the sliding process of the arc-shaped block, the outer wall of itself will abut against the arc surface of the telescopic end of the telescopic abutting plate to generate a reaction force. The arc surface of the telescopic end of the telescopic abutting plate contracts towards the inside of its fixed end through the reaction force. At the same time, the U-shaped plate limits the telescopic abutting plate. At this time, the arc surface of the arc-shaped block is pressed by the arc surface of the telescopic end of the telescopic abutting plate or is located between the arc surfaces of the telescopic ends of two telescopic abutting plates.

[0009] According to the above technical solution, the tops of the mounting components are directly opposite to the mounting holes. The arc surfaces of the telescopic ends of the telescopic abutting plates are all located on the movement track of the arc-shaped block, and springs are built into the telescopic abutting plates.

[0010] According to the above technical solution, the anti-exposure device includes a hinged pull plate, a plurality of fixed plates and a plurality of arc-shaped spring pieces. The hinged pull plate is hinged at the outer wall of the protective shell at one end away from the device body, and a U-shaped groove is opened inside the hinged pull plate. The tops of the plurality of fixed plates are equidistant and fixedly installed on the top of the inner wall of the U-shaped groove of the hinged pull plate. The plurality of arc-shaped spring pieces are fixedly installed on the outer wall of the fixed plate, and the plurality of arc-shaped spring pieces are relatively distributed. When the protective shell moves toward the direction close to the device body, the hinged pull plate is driven to move synchronously. When the upper and lower hinged pull plates are re-engaged, the hinged pull plate is re-engaged. When the upper and lower hinged pull plates are in contact, a resistance force is generated, and the resistance force causes the hinge shaft between the upper and lower hinged pull plates and the protective shell to start rotating, and drives the hinged pull plates to move away from the left and right outer walls of the device body. When the hinged pull plates move toward the device body, they drive the fixed plates to move synchronously, and the fixed plates drive the arc-shaped spring pieces to move synchronously. The arc surface of the arc-shaped spring piece contacts the arc surface of the outer wall of the wiring harness. As the arc-shaped spring piece continues to move and is guided by the arc surface of the arc-shaped spring piece, the arc-shaped spring piece is deformed by the resistance force between the arc-shaped spring piece and the wiring harness and squeezes the wiring harness into itself.

[0011] According to the above technical solution, a torsion spring is arranged between the end of the hinged pull plate away from the device body and the protective shell, and the arc surfaces of several arc-shaped spring sheets are in contact with the outer wall of the wiring harness.

[0012] According to the above technical scheme, the anti-exposure device also includes a vertical plate, an L-shaped telescopic spring plate and a rotating column. The vertical plate is fixedly installed at the edge of the protective shell away from the device body, the telescopic end of the L-shaped telescopic spring plate is hinged at the outer wall of the vertical plate away from the device body, and the fixed end of the L-shaped telescopic spring plate is provided with a square groove, and both ends of the rotating column are rotatably installed on the inner wall of the square groove of the fixed end of the L-shaped telescopic spring plate, and the outer wall of the rotating column contacts the outer wall of the hinged pull plate. When the hinged pull plate rotates in an arc trajectory with the hinge axis as the axis, it will resist the outer wall of the rotating column, and the rotating column will cause the hinge axis of the L-shaped telescopic spring plate to generate a rotational force through the resistance force. At this time, the hinge axis between the L-shaped telescopic spring plate and the vertical plate starts to rotate. When the L-shaped telescopic spring plate starts to move in an arc trajectory, the rotating column that the hinged pull plate resists will slide along the outer wall of the hinged pull plate, and the rotating column starts to rotate through the friction force of the sliding.

[0013] According to the above technical solution, the anti-collision device includes a hook-shaped plate, a sliding plate, several inclined plates and a connecting column. One end of the hook-shaped plate close to the device main body is hinged to the outer wall of the fixed end of the L-shaped telescopic spring plate. The sliding plate is slidably installed on the surface of the protective shell away from the device main body. The sliding plate is hinged to one end of the hook-shaped plate away from the device main body. The bottoms of several inclined plates are all hinged to the top of the sliding plate. The several inclined plates are symmetrically distributed. The outer wall of the connecting column is hinged to the top of the inclined plate. The L-shaped telescopic spring plate drives the hook-shaped plate to move synchronously along an arc trajectory. The bottom of one end of the hook-shaped plate close to the axis of the protective shell is limited by the sliding plate. At this time, the hinge shaft of the hook-shaped plate starts to rotate and pushes the sliding plate to slide along the top of the protective shell towards its center direction. The sliding plate drives the inclined plates to move synchronously. When the two side inclined plates move synchronously, their tops are both limited by the connecting column. At this time, the hinge shaft between the inclined plate and the connecting column starts to rotate and pushes the connecting column to move upward.

[0014] According to the above technical solution, the anti-collision device further includes a support plate, a condenser plate, a transmission plate, an L-shaped column and a contact column. The bottom of the support plate is fixedly installed at the edge of the top of the protective shell. Both ends of the condenser plate are hinged to the inner wall of the support plate. One end of the transmission plate away from the axis of the protective shell is fixedly installed on the inner wall of the condenser plate. The top of the L-shaped column is fixedly installed at the bottom of the connecting column. The outer wall of the contact column is fixedly installed at one end of the L-shaped column close to the condenser plate. When the connecting column moves upward, it drives the L-shaped column to move synchronously, and the L-shaped column drives the contact column to move synchronously. When the contact column moves upward, the support plate limits the condenser plate to keep it stationary, and the condenser plate limits the transmission plate. At this time, the arc surface of the contact column contacts the arc surface of one end of the transmission plate close to the center of the protective shell to generate a contact force. The transmission plate, through the contact force and arc surface guidance with the contact column, promotes the transmission plate to move away from the center of the protective shell. At this time, the transmission plate contacts the condenser plate to move synchronously. Under the contact of the transmission plate, the hinge shaft between the condenser plate and the support plate starts to rotate, and the condenser plate flips upward with the hinge shaft as the axis. At this time, the inclined surface of the condenser plate is located above the heat dissipation port of the protective shell.

[0015] According to the above technical solution, torsion springs are arranged between both ends of the condenser plate and the inner wall of the support plate. The condenser plate is located above the heat dissipation holes of the protective shell. The outer wall of the transmission plate is located on the movement track of the outer wall of the contact column.

[0016] A method for using a protection device for a vehicle wiring harness connector includes the following steps:

[0017] S1: When installing the device main body into the engine compartment, connect the wiring harness through the connecting seat. At the same time, the upper and lower protective shells move synchronously towards the device main body direction, and the protective shell is made of anti-magnetic material;

[0018] S2: Then, the lower protective shell drives the installation component to move towards the inside of the installation hole of the upper protective shell. When the upper and lower protective shells gather, the installation component is clamped into the inside of the installation hole. At this time, the upper and lower protective shells are fixed, and the covering device body completes the protection work.

[0019] S3: When it is necessary to install the protective shell inside the engine room, the staff adjusts the installation orientation with the engine room by moving the fixing component inside the slide rail. When the appropriate installation orientation is determined, the fixing component is clamped into the installation location inside the engine room. Then, the staff fixes the fixing component and the installation location with bolts to complete the installation work.

[0020] S4: At the same time, when the fixing component slides, it drives the arc-shaped block to move synchronously. During the sliding process of the arc-shaped block, the outer wall of itself will contact the arc surface of the telescopic contact plate's telescopic end to generate a contact force. The arc surface of the telescopic contact plate's telescopic end contracts towards the inside of its fixed end through the contact force. At the same time, the U-shaped plate limits the telescopic contact plate. At this time, the arc surface of the arc-shaped block is pressed by the arc surface of the telescopic contact plate's telescopic end or is located between the arc surfaces of the two telescopic contact plates' telescopic ends.

[0021] The present invention provides a protection device and method for a vehicle wiring harness connector. It has the following beneficial effects:

[0022] (1) Through the setting of the anti-shaking device in the present invention, through the cooperation of the protective shell, installation component, slide rail, fixing component, arc-shaped block, U-shaped plate and telescopic contact plate, good protection of the device body is achieved. And relying on the material characteristics of the protective shell, the electromagnetic interference received by the device body is reduced. At the same time, the freely sliding fixing component can quickly adjust the installation orientation, avoiding the occurrence of installation misalignment, which leads to a decrease in installation tightness. At the same time, it will not increase the installation difficulty due to the small space, effectively promoting the speed of installing the protective shell inside the engine room. At the same time, relying on the telescopic contact plate to enhance the stability of the fixing component during the installation process, avoiding secondary sliding when the fixing component contacts the internal parts of the engine room during the alignment installation process by the staff, preventing the inconvenience brought by the staff needing to adjust the installation orientation multiple times and prolonging the installation duration.

[0023] (2) Through the setting of the anti-exposure device in the present invention, through the cooperation of the protective shell, articulated pull plate, fixing plate, arc-shaped elastic sheet, vertical plate, L-shaped telescopic elastic sheet and rotating column, relying on the arc-shaped elastic sheet to stably clamp the wiring harness. Then, under the push of the articulated pull plate, the arc-shaped elastic sheet pulls the wiring harness to move synchronously. Thus, the wiring harness near the connection port connected to the connection seat is in a straight posture, avoiding the risk of increased skin exposure of the wiring harness under the high temperature of the engine room due to the tortuous distribution of the wiring harness, effectively improving the service life of the wiring harness. At the same time, it causes the rotating column to change the pressing orientation of itself on the articulated pull plate by the rolling friction during rotation. The rotating column ensures that the articulated pull plate continuously and stably pushes the wiring harness, avoiding the articulated pull plate being irregular due to external interference and scratching the surface of the wiring harness, preventing the surface of the wiring harness from being damaged.

[0024] (3) The present invention effectively increases the inclination angle of the inclined plate by setting an anti-collision device through the cooperation of an L-shaped telescopic spring plate, a hook plate, a sliding plate, an inclined plate, a connecting column, a supporting plate, a focusing plate, a transmission plate, an L-shaped column and a resistance column, and provides good protection for the protective shell by relying on the overhead layer formed between the inclined plate and the protective shell. When the protective shell is loose or other parts are loose and cause the two to collide, the inclined plate will bear the impact force to prevent the impact object from directly contacting the protective shell, and avoid damage to the outer wall of the protective shell, thereby reducing the anti-interference effect; and expand the shielding range of the focusing plate on the heat dissipation port of the protective shell, to prevent liquid from entering the protective shell when oil or water leaks inside the cabin and corroding the device body, increasing the probability of damage. At the same time, the focusing plate gathers the lighting source of the protective shell during the installation process to prevent the light source from reflecting or dispersing, resulting in a decrease in brightness within the installation range.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] Please refer to Figures 1 - 8 One embodiment of the present invention is: a protection device for a vehicle wiring harness connector, including a device main body 1. A jack is provided inside the device main body 1, a connection seat 2 is arranged inside the jack of the device main body 1, and a wiring harness 3 is arranged inside the connection seat 2;

[0036] Anti-vibration devices 4 are arranged on both the upper and lower sides of the device main body 1. An anti-exposure device 5 is arranged on the periphery of the anti-vibration device 4, and an anti-collision device 6 is arranged on the side of the anti-exposure device 5 away from the device main body 1;

[0037] The anti-vibration device 4 includes two protective shells 41, which are respectively arranged above and below the device main body 1. Heat dissipation openings are provided inside both protective shells 41. Mounting holes are equidistantly arranged at the bottom of the upper protective shell 41. A number of mounting components 42 are fixedly installed equidistantly and at the top edge of the lower protective shell 41. A slide rail 43 is fixedly installed on the side of the protective shell 41 away from the axis of the device main body 1. A chute is provided at the top of the slide rail 43. A fixing component 44 is slidably installed inside the slide rail 43. An arc-shaped block 45 is fixedly installed on the side of the fixing component 44 away from the axis of the device main body 1. A U-shaped plate 46 is fixedly installed on the side of the slide rail 43 away from the axis of the device main body 1. A number of telescopic abutting plates 47 are fixedly installed equidistantly on the side of the U-shaped plate 46 close to the slide rail 43. The outer walls of the number of telescopic abutting plates 47 are all located inside the chute of the slide rail 43. Through the above cooperation, good protection of the device main body 1 is achieved, and the electromagnetic interference received by the device main body 1 is reduced depending on the material characteristics of the protective shell 41. At the same time, the freely sliding fixing component 44 can quickly adjust the installation orientation, avoiding the reduction of installation tightness caused by the occurrence of installation misalignment, and at the same time, the installation difficulty will not be increased due to the small space, effectively promoting the speed of installing the protective shell 41 inside the engine compartment; through the above cooperation, the stability of the fixing component 44 during the installation process is enhanced depending on the telescopic abutting plates 47, avoiding secondary sliding when the fixing component 44 contacts the internal components of the engine compartment during the alignment installation process by the staff, preventing the inconvenience of the installation process caused by the staff needing to adjust the installation orientation multiple times, and resulting in an extended installation duration.

[0038] The tops of the number of mounting components 42 are directly opposite to the mounting holes. The arc surfaces of the telescopic ends of the number of telescopic abutting plates 47 are all located on the movement track of the arc-shaped block 45, and springs are built in the telescopic abutting plates 47.

[0039] During use, when the device body 1 is installed inside the cabin, the wiring harness 3 is connected through the connecting seat 2, and the upper and lower protective shells 41 move synchronously toward the device body 1, and the protective shells 41 are made of anti-magnetic material. Then the lower protective shell 41 drives the installation component 42 to move toward the inner direction of the installation hole of the upper protective shell 41. When the upper and lower protective shells 41 are gathered together, the installation component 42 is inserted into the installation hole. At this time, the upper and lower protective shells 41 are fixed and cover the device body 1 to complete the protection work. When the protective shell 41 needs to be installed inside the cabin, the staff moves the fixing component 44 inside the slide rail 43 to adjust the installation orientation with the inside of the cabin. When the appropriate installation orientation is determined, the fixing component 44 is inserted into the installation position inside the cabin. Then the staff fixes the fixing component 44 to the installation position with bolts to complete the installation work. The above cooperation can achieve good protection of the device body 1, and rely on the material properties of the protective shell 41 to reduce the electromagnetic interference to the device body 1, and freely slide The fixing assembly 44 can quickly adjust the installation position to avoid the occurrence of installation misalignment, which leads to reduced installation tightness. At the same time, it will not increase the difficulty of installation due to small space, and effectively promotes the speed of installing the protective shell 41 inside the cabin. At the same time, when the fixing assembly 44 slides, it drives the arc block 45 to move synchronously. During the sliding process of the arc block 45, its own outer wall will resist the arc surface of the telescopic end of the telescopic resistance plate 47 to generate a resistance force. The arc surface of the telescopic end of the telescopic resistance plate 47 shrinks toward the inside of its own fixed end through the resistance force. At the same time, the U-shaped plate 46 limits the telescopic resistance plate 47. At this time, the arc surface of the arc block 45 is suppressed by the arc surface of the telescopic end of the telescopic resistance plate 47 or is located between the telescopic ends of the two telescopic resistance plates 47. Through the above cooperation, the telescopic resistance plate 47 is relied on to enhance the stability of the fixing assembly 44 during installation, avoid secondary sliding when the fixing assembly 44 contacts the internal parts of the cabin during the positioning installation process of the staff, and prevent the staff from having to adjust the installation position multiple times, which brings inconvenience to the installation process and prolongs the installation time.

[0040] See also Figures 1 - 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-exposure device 5;

[0041] The anti-exposure device 5 includes a hinged pull plate 51, a plurality of fixing plates 52 and a plurality of arc-shaped elastic pieces 53. One end of the hinged pull plate 51 away from the device body 1 is hinged to the outer wall of the protective shell 41, and a U-shaped groove is formed inside the hinged pull plate 51. The tops of the plurality of fixing plates 52 are evenly and fixedly installed at the top of the inner wall of the U-shaped groove of the hinged pull plate 51. The plurality of arc-shaped elastic pieces 53 are fixedly installed on the outer walls of the fixing plates 52, and the plurality of arc-shaped elastic pieces 53 are distributed oppositely. Through the above cooperation, the arc-shaped elastic pieces 53 are used to stably clamp the wire harness 3. Then, under the push of the hinged pull plate 51, the arc-shaped elastic pieces 53 pull the wire harness 3 to move synchronously, so as to make the wire harness 3 near the connection port connected to the connection seat 2 in a straight posture, avoiding the risk of increased skin exposure of the wire harness 3 due to tortuous distribution in the high temperature of the engine room, and effectively improving the service life of the wire harness 3.

[0042] A torsion spring is arranged between one end of the hinged pull plate 51 away from the device body 1 and the protective shell 41. The arc surfaces of the plurality of arc-shaped elastic pieces 53 are all in contact with the outer wall of the wire harness 3.

[0043] The anti-exposure device 5 further includes a vertical plate 54, an L-shaped telescopic elastic plate 55 and a rotating column 56. The vertical plate 54 is fixedly installed at the edge of one side of the protective shell 41 away from the device body 1. One end of the telescopic end of the L-shaped telescopic elastic plate 55 away from the device body 1 is hinged to the outer wall of the vertical plate 54. A square groove is formed at the fixed end of the L-shaped telescopic elastic plate 55. Both ends of the rotating column 56 are rotatably installed at the inner wall of the square groove at the fixed end of the L-shaped telescopic elastic plate 55. The outer wall of the rotating column 56 is in contact with the outer wall of the hinged pull plate 51. Through the above cooperation, the rotating column 56 changes its pressing orientation on the hinged pull plate 51 by rolling friction during rotation. The rotating column 56 ensures that the hinged pull plate 51 continuously and stably pushes the wire harness 3, avoiding irregular movement of the hinged pull plate 51 due to external interference and scratching the surface of the wire harness 3, and preventing damage to the skin of the wire harness 3.

[0044] When in use, the protective shell 41 moves toward the direction of approaching the device body 1, driving the hinged pull plate 51 to move synchronously. When the upper and lower hinged pull plates 51 overlap and contact, a resistance force is generated. The resistance force causes the hinge shaft between the upper and lower hinged pull plates 51 and the protective shell 41 to start rotating, and drives the hinged pull plate 51 to move away from the left and right outer walls of the device body 1. When the hinged pull plate 51 moves toward the direction of approaching the device body 1, it drives the fixed plate 52 to move synchronously. The fixed plate 52 drives the arc-shaped spring piece 53 to move synchronously. The arc surface of the arc-shaped spring piece 53 contacts the arc surface of the outer wall of the wiring harness 3. As the arc-shaped spring piece 53 continues to move and is guided by the arc surface of the arc-shaped spring piece 53, the arc-shaped spring piece 53 is deformed by the resistance force between the wiring harness 3 and squeezes the wiring harness 3 into itself. Through the above cooperation, the wiring harness 3 is stably clamped by the arc-shaped spring piece 53. Then, under the push of the hinged pull plate 51, the arc-shaped spring piece 53 pulls the wiring harness 3 to move synchronously, thereby causing the wiring harness 3 to move synchronously with the wiring harness 3. The wiring harness 3 near the connection port of the socket 2 is in a straight position, so as to avoid the risk of the wiring harness 3 being exposed due to the zigzag distribution under the high temperature of the cabin, and effectively improve the service life of the wiring harness 3; when the hinged pull plate 51 rotates in an arc trajectory with the hinge axis as the axis, it will contact the outer wall of the rotating column 56, and the rotating column 56 will cause the hinge axis of the L-shaped telescopic spring plate 55 to generate a rotation force through the resistance force. At this time, the hinge axis between the L-shaped telescopic spring plate 55 and the vertical plate 54 starts to rotate, and when the L-shaped telescopic spring plate 55 opens When it starts to move in an arc trajectory, the rotating column 56 that the hinged pull plate 51 contacts will slide along the outer wall of the hinged pull plate 51, and the rotating column 56 starts to rotate due to the friction force of sliding. Through the above cooperation, the rotating column 56 changes its own pressing direction on the hinged pull plate 51 by the rolling friction during rotation. The rotating column 56 ensures that the hinged pull plate 51 continuously and stably pushes the wire harness 3, avoids the hinged pull plate 51 from being disturbed by external force and causing irregularity, thereby scratching the surface of the wire harness 3 and preventing the surface of the wire harness 3 from being damaged.

[0045] See also Figures 1 - 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-collision device 6;

[0046] The anti-collision device 6 includes a hook plate 61, a sliding plate 62, a plurality of inclined plates 63 and a connecting column 64. The hook plate 61 is hinged at one end close to the device body 1 at the outer wall of the fixed end of the L-shaped telescopic spring plate 55. The sliding plate 62 is slidably installed on the surface of the protective shell 41 on the side away from the device body 1. The sliding plate 62 is hinged at the end of the hook plate 61 away from the device body 1. The bottoms of the plurality of inclined plates 63 are all hinged at the top of the sliding plate 62. The plurality of inclined plates 63 are symmetrically distributed, and the outer wall of the connecting column 64 is hinged at the top of the inclined plate 63. The above cooperation effectively increases the inclination angle of the inclined plate 63, and relies on the overhead layer formed between the inclined plate 63 and the protective shell 41 to provide good protection for the protective shell 41. When the protective shell 41 is loose or other components are loose, resulting in a collision between the two, the inclined plate 63 bears the impact force to prevent the impactor from directly contacting the protective shell 41, and to prevent the outer wall of the protective shell 41 from being damaged, thereby reducing the anti-interference effect.

[0047] The anti-collision device 6 also includes a support plate 65, a focusing plate 66, a transmission plate 67, an L-shaped column 68 and a resistance column 69. The bottom of the support plate 65 is fixedly installed at the top edge of the protective shell 41. Both ends of the focusing plate 66 are hinged at the inner wall of the support plate 65. The end of the transmission plate 67 away from the axis of the protective shell 41 is fixedly installed on the inner wall of the focusing plate 66. The top of the L-shaped column 68 is fixedly installed at the bottom of the connecting column 64. The outer wall of the resistance column 69 is fixedly installed on the end of the L-shaped column 68 close to the focusing plate 66. Through the above cooperation, the shielding range of the heat dissipation port of the protective shell 41 by the focusing plate 66 is expanded to avoid liquid from entering the protective shell 41 when the cabin leaks oil or water, corroding the device body 1 and increasing the probability of damage. At the same time, the focusing plate 66 gathers the lighting light source of the protective shell 41 during the installation process to avoid reflection or dispersion of the light source, which leads to a decrease in brightness within the installation range.

[0048] Torsion springs are provided between the two ends of the focusing plate 66 and the inner wall of the support plate 65 . The focusing plate 66 is located above the heat dissipation holes of the protective shell 41 . The outer wall of the transmission plate 67 is located on the movement track of the outer wall of the abutment column 69 .

[0049] During use, the L-shaped telescopic elastic plate 55 drives the hook-shaped plate 61 to move synchronously along an arc trajectory. The bottom of the end of the hook-shaped plate 61 close to the axis of the protective shell 41 is limited by the sliding plate 62. At this time, the hinge shaft of the hook-shaped plate 61 starts to rotate and pushes the sliding plate 62 to slide along the top of the protective shell 41 towards its center. The sliding plate 62 drives the inclined plate 63 to move synchronously. When the inclined plates 63 on both sides move synchronously, the tops of both are limited by the connecting columns 64. At this time, the hinge shaft between the inclined plate 63 and the connecting column 64 starts to rotate and pushes the connecting column 64 to move upward. Through the above cooperation, the inclination angle of the inclined plate 63 is effectively increased, and a good protection is provided for the protective shell 41 by relying on the overhead layer formed between the inclined plate 63 and the protective shell 41. When the protective shell 41 is loose or other components are loose, resulting in a collision between the two, the inclined plate 63 receives the impact force to prevent the impact object from directly contacting the protective shell 41, avoiding damage to the outer wall of the protective shell 41 and thus reducing the anti-interference effect; when the connecting column 64 moves upward, it drives the L-shaped column 68 to move synchronously, and the L-shaped column 68 drives the abutting column 69 to move synchronously. When the abutting column 69 moves upward, the support plate 65 limits the condenser plate 66 to keep it stationary, and the condenser plate 66 limits the transmission plate 67. At this time, the arc surface of the abutting column 69 contacts the arc surface of the end of the transmission plate 67 close to the center of the protective shell 41 to generate a abutting force. The transmission plate 67, through the abutting force and arc surface guidance between it and the abutting column 69, promotes the transmission plate 67 to move away from the center of the protective shell 41. At this time, the transmission plate 67 abuts the condenser plate 66 to move synchronously. The condenser plate 66 starts to rotate around its hinge axis with the support plate 65 under the abutment of the transmission plate 67. The condenser plate 66 flips upward with the hinge axis as the center. At this time, the inclined surface of the condenser plate 66 is located above the heat dissipation port of the protective shell 41. Through the above cooperation, the shielding range of the condenser plate 66 for the heat dissipation port of the protective shell 41 is expanded, avoiding the liquid entering the protective shell 41 when the engine room leaks oil or water, eroding the device main body 1 and increasing the damage probability. At the same time, the condenser plate 66 gathers the illumination light source during the installation of the protective shell 41, avoiding the phenomenon of light reflection or dispersion, which reduces the brightness in the installation range.

[0050] A method for using a protection device for a vehicle wiring harness connector includes the following steps:

[0051] S1: When installing the device main body 1 into the engine room, the wiring harness 3 is connected through the connecting seat 2. At the same time, the upper and lower protective shells 41 move synchronously towards the device main body 1, and the protective shell 41 is made of anti-magnetic material;

[0052] S2: Then the lower protective shell 41 drives the installation component 42 to move towards the inside of the installation hole of the upper protective shell 41. When the upper and lower protective shells 41 are gathered, the installation component 42 is snapped into the installation hole. At this time, the upper and lower protective shells 41 are fixed and the device main body 1 is covered to complete the protection work;

[0053] S3: When it is necessary to install the protective shell 41 inside the engine compartment, the staff adjusts the installation orientation with the engine compartment by moving the fixing component 44 inside the slide rail 43. When the appropriate installation orientation is determined, the fixing component 44 is snapped into the installation location inside the engine compartment. Then, the staff fixes the fixing component 44 to the installation location with bolts to complete the installation work;

[0054] S4: At the same time, when the fixing component 44 slides, it drives the arc-shaped block 45 to move synchronously. During the sliding process of the arc-shaped block 45, the outer wall of itself will contact the arc surface of the telescopic contact plate 47 to generate a contact force. The arc surface of the telescopic end of the telescopic contact plate 47 contracts towards the inside of its fixed end through the contact force. At the same time, the U-shaped plate 46 limits the telescopic contact plate 47. At this time, the arc surface of the arc-shaped block 45 is pressed by the arc surface of the telescopic end of the telescopic contact plate 47 or is located between the telescopic ends of the two telescopic contact plates 47.

[0055] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
