Description

Technical Field

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

[0002] The automotive wiring harness connector is an important component used to connect the automotive electrical circuits. Its function is to connect the various circuits in the vehicle's electrical circuits, provide a good path for current flow and electrical signal transmission, and thus achieve normal and stable operation of the circuit.

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

[0004] However, the device still has some shortcomings: the device extends the service life of the wiring harness connector through good anti-interference ability, but when the protective shell is installed inside the vehicle, due to the relatively small space and the complex surrounding lines and components, it is easy to increase the difficulty of installing the protective shell to a certain extent. At the same time, it is easy to misalign during installation, resulting in reduced installation tightness. Summary of the invention

[0005] In view of 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 technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A protective device for a vehicle wiring harness connector, comprising a device body, a socket is provided inside the device body, a connection seat is provided inside the socket of the device body, and a wiring harness is provided inside the connection seat; The upper and lower sides of the device body are both provided with anti-sway devices, the periphery of the anti-sway device is provided with an anti-exposure device, and the side of the anti-exposure device away from the device body is provided with an anti-collision device; The anti-sway device includes two protective shells, which are respectively arranged above and below the device body, and heat dissipation ports are provided inside the two protective shells. Mounting holes are equidistantly provided at the bottom of the upper protective shell, and a plurality of mounting components are equidistantly and fixedly installed 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 slide groove is provided on the top of the slide rail, and a fixed component is slidably installed inside the slide rail, and an arc block is fixedly installed on the side of the fixed 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, and a plurality of telescopic contact plates are equidistantly and fixedly installed on the side of the U-shaped plate close to the slide rail, and the outer walls of the plurality of telescopic contact plates are all located inside the slide groove of the slide rail. When the device body is installed inside the cabin, the wiring harness is connected through the connecting seat, and the upper and lower protective shells move synchronously toward the direction of the device body, and the protective shells are made of anti-magnetic material , then the lower protective shell drives the installation component to move toward the inner direction of the installation hole of the upper protective shell, and when the upper and lower protective shells are gathered, the installation component is inserted into the installation hole. At this time, the upper and lower protective shells are fixed and the covering device body completes the protection work. When the protective shell needs to be installed inside the cabin, the staff moves the fixing component inside the slide rail to adjust the installation orientation with the inside of the cabin. When the appropriate installation orientation is determined, the fixing component is inserted into the installation position inside the cabin. Then the staff fixes the fixing component to the installation position with bolts to complete the installation work; at the same time, the fixing component drives the arc block to move synchronously when sliding. During the sliding process of the arc block, its own outer wall will resist the arc surface of the telescopic end of the telescopic resistance plate to generate a resistance force. The arc surface of the telescopic end of the telescopic resistance plate shrinks toward the inside of its own fixed end through the resistance force, and at the same time, the U-shaped plate limits the telescopic resistance plate. At this time, the arc surface of the arc block is suppressed by the arc surface of the telescopic end of the telescopic resistance plate or is located between the telescopic ends of the two telescopic resistance plates.

[0007] According to the above technical solution, the tops of several of the mounting components are directly opposite to the mounting holes, the arc surfaces of the telescopic ends of several of the telescopic resistance plates are all located on the motion trajectory of the arc block, and the telescopic resistance plates are equipped with springs.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] The outer wall of the connecting column is hinged on the top of the inclined plate, and the hinge shaft between the inclined plate and the connecting column starts to rotate and pushes the sliding plate to slide along the top of the protective shell toward the center thereof.

[0012] According to the above technical solution, the anti-collision device also includes a support plate, a focusing plate, a transmission plate, an L-shaped column and a resistance column. The bottom of the support plate is fixedly installed at the top edge of the protective shell, and both ends of the focusing plate are hinged at the inner wall of the support plate. The end of the transmission plate away from the axis of the protective shell is fixedly installed on the inner wall of the focusing plate. The top of the L-shaped column is fixedly installed at the bottom of the connecting column. The outer wall of the resistance column is fixedly installed at the end of the L-shaped column close to the focusing plate. When the connecting column moves upward, it drives the L-shaped column to move synchronously, and the L-shaped column drives the resistance column to move synchronously. When the resistance column moves upward, the L-shaped column drives the resistance column to move synchronously. When the contact column moves upward, the support plate limits the focusing plate and remains stationary, and the focusing plate limits the transmission plate. At this time, the arc surface of the contact column contacts the arc surface of the transmission plate close to the center of the protective shell to generate a resistance force. The transmission plate is prompted to move away from the center of the protective shell through the resistance force between the contact column and the arc surface guidance. At this time, the transmission plate resists the focusing plate and moves synchronously. Under the resistance of the transmission plate, the hinge shaft between the focusing plate and the support plate begins to rotate, and the focusing plate flips upward with the hinge shaft as the axis. At this time, the inclined surface of the focusing plate is located above the heat dissipation port of the protective shell.

[0013] According to the above technical solution, torsion springs are arranged between the two ends of the focusing plate and the inner wall of the support plate, the focusing plate is located above the heat dissipation hole of the protective shell, and the outer wall of the transmission plate is located on the movement trajectory of the outer wall of the resistance column.

[0014] A method for using a protective device for a vehicle wiring harness connector comprises the following steps: S1: When the device body is installed inside the cabin, the wiring harness is connected through the connector, and the upper and lower protective shells move synchronously toward the device body, and the protective shells are made of anti-magnetic material; S2: The lower protective shell then drives the installation component to move toward the inner direction of the installation hole of the upper protective shell. When the upper and lower protective shells are gathered together, the installation component is inserted into the inner direction of the installation hole. At this time, the upper and lower protective shells are fixed and cover the main body of the device to complete the protection work; S3: When the protective shell needs to be installed inside the cabin, the staff moves the fixing component inside the slide rail to adjust the installation position inside the cabin. When the appropriate installation position is determined, the fixing component is inserted into the installation position inside the cabin. Then, the staff fixes the fixing component to the installation position with bolts to complete the installation work; S4: When the fixed component slides at the same time, it drives the arc block to move synchronously. During the sliding process of the arc block, its own outer wall will resist the arc surface of the telescopic end of the telescopic resistance plate to generate a resistance force. The arc surface of the telescopic end of the telescopic resistance plate shrinks toward the inside of its own fixed end through the resistance force. At the same time, the U-shaped plate limits the telescopic resistance plate. At this time, the arc surface of the arc block is suppressed by the arc surface of the telescopic end of the telescopic resistance plate or is located between the telescopic ends of the two telescopic resistance plates.

[0015] The present invention provides a protection device and method for a vehicle wiring harness connector, which has the following beneficial effects: (1) The present invention achieves good protection for the device body by setting an anti-sway device, through the coordination of a protective shell, a mounting assembly, a slide rail, a fixing assembly, an arc block, a U-shaped plate and a telescopic contact plate, and reduces the electromagnetic interference to the device body by relying on the material properties of the protective shell. At the same time, the freely sliding fixing assembly can quickly adjust the installation position to avoid the occurrence of installation misalignment resulting in reduced installation tightness, and at the same time, the installation difficulty is not increased due to the small space, which effectively promotes the speed of installing the protective shell inside the cabin. At the same time, the telescopic contact plate is used to enhance the stability of the fixing assembly during installation, to avoid secondary sliding when the fixing assembly contacts with the internal parts of the cabin during the installation process, and to prevent the staff from having to adjust the installation position multiple times, which brings inconvenience to the installation process and prolongs the installation time.

[0016] (2) The present invention sets an anti-exposure device, and cooperates with a protective shell, a hinged pull plate, a fixed plate, an arc-shaped spring sheet, a vertical plate, an L-shaped telescopic spring sheet and a rotating column. The arc-shaped spring sheet stably clamps the wire harness. Then, under the push of the hinged pull plate, the arc-shaped spring sheet pulls the wire harness to move synchronously, thereby causing the wire harness near the connection port of the connector to be in a straight position, avoiding the risk of the wire harness being exposed due to the tortuous distribution of the wire harness under the high temperature of the cabin, and effectively improving the service life of the wire harness; at the same time, the rotating column changes its own pressing position on the hinged pull plate by rolling friction during rotation. The rotating column ensures that the hinged pull plate continuously and stably pushes the wire harness, avoiding the hinged pull plate from being disturbed by external force and causing irregularity, thereby scratching the surface of the wire harness and preventing the surface of the wire harness from being damaged.

[0017] (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.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-Figure 8 One embodiment of the present invention is: a protective device for a vehicle wiring harness connector, comprising a device body 1, a socket is provided inside the device body 1, a connection seat 2 is provided inside the socket of the device body 1, and a wiring harness 3 is provided inside the connection seat 2; The device body 1 is provided with anti-sway devices 4 on both upper and lower sides, an anti-exposure device 5 is provided on the periphery of the anti-sway device 4, and an anti-collision device 6 is provided on the side of the anti-exposure device 5 away from the device body 1; The anti-sway device 4 includes two protective shells 41, which are respectively arranged above and below the device body 1. Heat dissipation ports are provided inside the two protective shells 41. Mounting holes are equidistantly provided at the bottom of the upper protective shell 41. Several mounting components 42 are equidistantly and fixedly installed 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 body 1. A slide groove is provided on the top of the slide rail 43. A fixing component 44 is slidably installed inside the slide rail 43. An arc block 45 is fixedly installed on the side of the fixing component 44 away from the axis of the device 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 body 1. Several telescopic abutment plates 47 are equidistantly and fixedly installed on the side of the U-shaped plate 46 close to the slide rail 43. The outer walls of the plates 47 are all located inside the slide grooves of the slide rails 43. Through the above cooperation, good protection of the device body 1 is achieved, and the electromagnetic interference to the device body 1 is reduced by relying on the material properties of the protective shell 41. At the same time, the freely sliding fixed component 44 can quickly adjust the installation position to avoid installation misalignment and reduce installation tightness. At the same time, the installation difficulty will not be increased due to the small space, and the speed of installing the protective shell 41 inside the cabin is effectively improved; through the above cooperation, the telescopic resistance plate 47 is relied on to enhance the stability of the fixed component 44 during installation, and secondary sliding of the fixed component 44 when it contacts the internal parts of the cabin during the installation process of the staff is avoided, so as to prevent the staff from having to adjust the installation position multiple times, which brings inconvenience to the installation process and prolongs the installation time.

[0022] The tops of the plurality of mounting components 42 are directly opposite to the mounting holes, the arc surfaces of the telescopic ends of the plurality of telescopic contact plates 47 are all located on the movement track of the arc block 45, and the telescopic contact plates 47 are internally provided with springs.

[0023] 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.

[0024] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-exposure device 5; The anti-exposure device 5 includes a hinged pull plate 51, a plurality of fixed plates 52 and a plurality of arc-shaped spring clips 53. The hinged pull plate 51 is hinged at one end away from the device body 1 at the outer wall of the protective shell 41, and a U-shaped groove is opened inside the hinged pull plate 51. The tops of the plurality of fixed plates 52 are equidistant and fixedly installed on the top of the inner wall of the U-shaped groove of the hinged pull plate 51. The plurality of arc-shaped spring clips 53 are all fixedly installed on the outer wall of the fixed plate 52, and the plurality of arc-shaped spring clips 53 are relatively distributed. Through the above cooperation, the wire harness 3 is stably clamped by the arc-shaped spring clips 53. Then, under the push of the hinged pull plate 51, the arc-shaped spring clips 53 pull the wire harness 3 to move synchronously, thereby causing the wire harness 3 near the connection port of the connecting seat 2 to be in a straight posture, avoiding the risk of the wire harness 3 being zigzag distributed under the high temperature of the cabin to increase the risk of skin exposure, and effectively improving the service life of the wire harness 3.

[0025] A torsion spring is arranged between the end of the hinged pull plate 51 away from the device body 1 and the protective shell 41 , and the arc surfaces of the plurality of arc-shaped spring pieces 53 are in contact with the outer wall of the wiring harness 3 .

[0026] The anti-exposure device 5 also includes a vertical plate 54, an L-shaped telescopic spring plate 55 and a rotating column 56. The vertical plate 54 is fixedly installed on the edge of the protective shell 41 away from the device body 1. The telescopic end of the L-shaped telescopic spring plate 55 is hinged to the outer wall of the vertical plate 54 away from the device body 1. A square groove is opened at the fixed end of the L-shaped telescopic spring plate 55. Both ends of the rotating column 56 are rotatably installed on the inner wall of the square groove of the fixed end of the L-shaped telescopic spring plate 55. The outer wall of the rotating column 56 contacts the outer wall of the hinged pull plate 51. Through the above cooperation, the rotating column 56 changes its own pressing direction 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 wiring harness 3, avoids the hinged pull plate 51 from being disturbed by external force and causing irregularity, thereby scratching the surface of the wiring harness 3, and prevents the surface of the wiring harness 3 from being damaged.

[0027] 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.

[0028] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-collision device 6; 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 end of the hook plate 61 close to the device body 1 is hinged 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 side of the protective shell 41 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 around the axis of the protective shell 41. 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. The overhead layer formed between the inclined plate 63 and the protective shell 41 provides 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.

[0029] 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.

[0030] 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 , and the outer wall of the transmission plate 67 is located on the movement track of the outer wall of the abutment column 69 .

[0031] When in use, the L-shaped telescopic spring plate 55 drives the hook plate 61 to move synchronously in an arc track, and the bottom of the hook plate 61 close to the axis of the protective shell 41 is limited by the sliding plate 62. At this time, the hinge axis of the hook plate 61 starts to rotate and pushes the sliding plate 62 to slide along the top of the protective shell 41 toward its center. The sliding plate 62 drives the inclined plate 63 to move synchronously. When the inclined plates 63 on both sides move synchronously, their tops are limited by the connecting column 64. At this time, the hinge axis between the inclined plate 63 and the connecting column 64 starts to rotate and pushes the connecting column 6 4 moves upward, and the above cooperation effectively increases the inclination angle of the inclined plate 63, and the protective shell 41 is well protected by the overhead layer formed between the inclined plate 63 and the protective shell 41. When the protective shell 41 is loose or other parts are loose, resulting in a collision between the two, the inclined plate 63 bears the impact force to prevent the impact object 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; 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 abutment column 69 to move synchronously. The supporting plate 65 limits the focusing plate 66 to remain stationary when the abutment column 69 moves upward, and the focusing plate 66 limits the transmission plate 67. At this time, the arc surface of the abutment column 69 contacts the arc surface of the transmission plate 67 near the center of the protective shell 41 to generate a resistance force. The transmission plate 67 is guided by the resistance force between the abutment column 69 and the arc surface, so that the transmission plate 67 moves away from the center of the protective shell 41. At this time, the transmission plate 67 abuts against the focusing plate 66 and moves synchronously. Under the resistance of the transmission plate 67, the focusing plate 66 abuts against the supporting plate 66. 65 begins to rotate, and the focusing plate 66 flips upward with the focusing plate as the axis. At this time, the inclined surface of the focusing plate 66 is located above the heat dissipation port of the protective shell 41. The above cooperation expands the shielding range of the focusing plate 66 on the heat dissipation port of the protective shell 41, thereby preventing liquid from entering the protective shell 41 and corroding the device body 1 when oil or water leaks inside the cabin, 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 reduced brightness within the installation range.

[0032] A method for using a protective device for a vehicle wiring harness connector comprises the following steps: S1: When the device body 1 is installed inside the cabin, the wiring harness 3 is connected through the connecting seat 2, and at the same time, 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; S2: The lower protective shell 41 then drives the mounting assembly 42 to move toward the inner direction of the mounting hole of the upper protective shell 41. When the upper and lower protective shells 41 are gathered together, the mounting assembly 42 is inserted into the inner direction of the mounting hole. At this time, the upper and lower protective shells 41 are fixed to each other and cover the device body 1 to complete the protection work. S3: When the protective shell 41 needs to be installed inside the cabin, the staff moves the fixing assembly 44 inside the slide rail 43 to adjust the installation orientation inside the cabin. When a suitable installation orientation is determined, the fixing assembly 44 is inserted into the installation position inside the cabin. Then, the staff fixes the fixing assembly 44 to the installation position with bolts to complete the installation work; S4: When the fixed component 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.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
