Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to connectors, wiring harness assemblies and automotive CAN buses. Background Art

[0002] Connectors are widely used in automobile circuits and communication transmission. The connector includes a housing and terminals. The terminals are arranged in the housing. The connector includes a male head and a female head. When in use, the male head is inserted into the female head to connect the terminals to each other, thus completing the connection between electrical components.

[0003] When the existing connector is in use, the male head and the female head are connected. However, when it needs to be repaired or shipped out of the factory, the male head and the terminal are exposed to the outside. When subjected to external force, the male head or the terminal is easily deformed, resulting in deviations in the subsequent connection of the connector, which can easily cause damage to the device. When the male head and the female head are connected, they are only connected by plugging. When the vibration generated by the car is large during driving, the male head and the female head are easily separated, causing the connector to lose its function.

[0004] Therefore, the present invention proposes a connector, a wiring harness assembly and an automobile CAN bus to solve this problem. Summary of the invention

[0005] The purpose of this application is to solve the problems in the above-mentioned background technology, and the application provides a connector, a wiring harness assembly and a car CAN bus.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] Connectors, including:

[0008] A plug-in end, which is connected to an electrical appliance and has a plug-in cavity;

[0009] A connection end, on which an insertion block for being inserted into the insertion cavity is installed, and a receiving hole for receiving the terminal is provided on the insertion block, and a shielding plate is movably installed on the connection end, and there are two shielding plates, which are symmetrically and movably installed on both sides of the connection end, and the shielding plates are used to shield the opening of the receiving hole, and a connecting piece is installed between the shielding plates, and the connecting piece is used to connect the two shielding plates so that the movement of the shielding plates at the connection end is restricted;

[0010] The plug-in rod is installed on the plug-in end. The shielding plate is provided with an plug-in hole for accommodating the plug-in rod. The shielding plate is rotated so that the plug-in hole can accommodate the plug-in rod.

[0011] Furthermore, an inclined block is slidably mounted on the insertion end through a connecting spring, a force-bearing inclined surface is provided on the inclined block, the inclined block is connected to the insertion rod so that the insertion rod and the insertion end are slidably matched, and a resistance plate is mounted on the insertion block, and a resistance plate is provided with a resistance inclined surface parallel to the inclined surface of the inclined block;

[0012] The connecting spring applies a force to the inclined block to resist the resistance plate. The force is applied to the resistance inclined surface through the force-bearing inclined surface, which will generate a force to separate the connecting end from the insertion end. The insertion rod is inserted in the insertion hole, which limits the tendency of the two to move away from each other, thereby reducing the gap of the insertion rod in the insertion hole, further increasing the strength of the connection between the connecting end and the insertion end, and reducing the possibility of the two being separated due to large vibrations when the car is driving.

[0013] Further, a slide groove is provided on the connecting end, a rotation groove is provided at one end of the slide groove away from the connecting end, a movable rod is installed on the shielding plate, two parallel planes are provided on the side wall of the movable rod, the height of the slide groove is equal to the distance between the two planes, and the diameter of the rotation groove is greater than or equal to the diameter of the movable rod;

[0014] When it is necessary to release the shielding plate from the opening of the accommodating hole, first slide the shielding plate in the direction away from the connecting end, so that the movable rod slides into the rotating groove, and the movable rod can rotate in the rotating groove, so that the shielding plate can be rotated at this time. Through the above design, when in use, the restriction of the movable rod by the slide groove further increases the restriction on the rotation of the shielding plate, and the cooperation between the slide groove and the movable rod plays a fool-proof role, thereby increasing the practicability of the device.

[0015] Further, the connecting member includes a limit rod installed on one of the shielding plates, a limit hole for accommodating the limit rod is opened on the abutment plate, a rotating rod is installed on the other shielding plate, a connecting rod is rotatably arranged on the rotating rod, a rubber hoop for connecting with the limit rod is installed on the connecting rod, an ear plate is installed on the shielding plate on which the limit rod is installed, an insertion hole is opened on the ear plate, a limited sliding rod is slidably installed on the connecting end through an abutment spring, and the limited sliding rod is used to be inserted in the insertion hole;

[0016] When in use, first rotate the shielding plate so that its upper surface is parallel to the upper surface of the connecting end, then slide the shielding plate so that the limit rod is inserted into the limit hole, rotate the connecting rod to connect the rubber hoop to the limit rod, and press the limit slide rod downward while sliding. When the shielding plate slides to the maximum limit, release the limit slide rod, and insert the limit slide rod into the insertion hole through the resistance spring reset. At this time, the inner wall of the insertion hole is restricted by the side wall of the limit slide rod, so that the sliding of the shielding plate is restricted, thereby increasing the stability of the shielding plate when in use.

[0017] Furthermore, a slide plate is slidably installed in the slide groove, the movable rod is rotatably connected to the slide plate, a torsion spring is installed between the slide plate and the movable rod, and an inclined plate is installed on the connecting end, and the inclined plate is used to limit the rotation range of the shielding plate;

[0018] When the sliding shield plate releases the connection between the limit rod and the limit hole, the rubber block is also released from the accommodating hole. At this time, the torsion spring is reset, so that the shield plate releases the blocking of the accommodating hole opening, and when the shield plate is rotated to contact the inclined plate through the blocking of the inclined plate, the rotation path of the shield plate is restricted, and the mutual cooperation of the blocking of the inclined plate and the reset of the torsion spring can maintain the rotation angle of the shield plate, so that when the connecting end and the plug-in end are connected, the shield plate drives the part of the ear plate with the plug-in hole to be located above the plug-in end, so that the shield plate does not need to be rotated manually, so that when the connecting end and the plug-in end are plugged in, the plug-in rod can be plugged into the plug-in hole, which further increases the practicability of the device.

[0019] Furthermore, a side plate is installed on the connecting end, a guide rod is slidably installed on the side plate, a mounting plate connected to the guide rod is slidably installed on the connecting end, and the sliding limit rod is installed on the mounting plate;

[0020] The guide rod passes through the side plate to form a channel. When in use, the inner wall of the channel restricts the side wall of the guide rod, so that the guide rod can only slide on the side plate in a straight line, and then the mounting plate and the sliding limit rod can only slide on the insertion end in a straight line, which increases the stability of the sliding limit rod when sliding. The resistance spring is sleeved on the outer wall of the guide rod. The deformation direction of the resistance spring is also restricted by the restriction of the side wall of the guide rod, which increases the stability of the resistance spring when deformed.

[0021] Furthermore, an inner cavity is provided on the connecting end, the inserting block is slidably installed in the inner cavity, and a pushing spring is installed between the inserting block and the inner wall of the inner cavity;

[0022] When in use, the push spring pushes the plug-in block away from the inner cavity, so that the plug-in block contacts the baffle plate, and the sliding of the baffle plate is limited by the slide limit rod, thereby reducing the gap between the baffle plate and the plug-in block when the baffle plate protects the terminal, further increasing the connection strength between the two and increasing the protection effect of the device on the terminal.

[0023] The present application also provides a wiring harness assembly, including any of the above connectors, and also including a wire, a threaded sleeve is movably mounted on the wire, the threaded sleeve is provided with an internal thread, an end wire electrically connected to a terminal is mounted on the insertion block, a connecting sleeve is sleeved on the end wire, the connecting sleeve is provided with an external thread, and the threaded sleeve is threadedly connected to the connecting sleeve;

[0024] The wire and the end wire have inner cores. When connecting, the inner core of the wire is inserted into the end wire to connect the inner cores of the two. After the connection is completed, the threaded sleeve is slid and rotated to make the threaded sleeve and the connecting sleeve threadedly connected, thereby connecting the wiring harness assembly to the connecting end.

[0025] Furthermore, an extension plate is installed on the wire, a screw is threadedly connected to the extension plate, and a through hole for the screw to pass through is opened on the connecting end;

[0026] When inserting, first rotate the screw rod so that the screw rod contacts the insertion block, so that when the connecting end and the insertion end are connected, the insertion block will not retract into the inner cavity due to external force, resulting in the possibility of inadequate connection between the connecting end and the insertion end, thereby increasing the practicality of the device.

[0027] The present application further provides an automotive CAN bus, which is used to connect with the above-mentioned wiring harness assembly, including a terminal and a receiving head installed on the terminal, wherein a connector for plugging into the receiving head is installed on the wire;

[0028] The wire is inserted into the receiving head through the connector, so that the wiring harness assembly is connected to the vehicle CAN bus, so that the vehicle CAN bus can be used normally.

[0029] The beneficial effects of this application are as follows:

[0030] The present application installs a baffle plate on the connecting end. During transportation, the opening of the accommodating hole is blocked by the baffle plate to protect the terminal, and the movement of the baffle plate is restricted by the cooperation of the connecting piece, thereby increasing the stability of the baffle plate when in use. When it is needed, the connecting end is inserted into the plug-in end, and the plug-in hole is connected to the plug-in rod through the movement of the baffle plate, thereby further increasing the connection strength between the connecting end and the plug-in end, reducing the possibility of separation of the two during use, and increasing the practicality of the device.

[0031] The present application applies a force to the inclined block to resist the contact plate through the connecting spring. The force is applied to the contact inclined surface through the force-bearing inclined surface, which will generate a force that separates the connecting end from the insertion end. The insertion rod is inserted into the insertion hole, which limits the tendency of the two to move away from each other, thereby reducing the gap of the insertion rod in the insertion hole, further increasing the strength of the connection between the connecting end and the insertion end, and reducing the possibility of the two being separated due to large vibrations when the car is driving.

[0032] When it is necessary to release the shielding plate from the opening of the accommodating hole, the shielding plate is first slid in the direction away from the connecting end, so that the movable rod slides into the rotating groove, and the movable rod can rotate in the rotating groove, so that the shielding plate can be rotated at this time. Through the above design, when in use, the restriction of the slide groove on the movable rod further increases the restriction on the rotation of the shielding plate, and the cooperation between the slide groove and the movable rod plays a fool-proof role, thereby increasing the practicality of the device.

[0033] When the present application is in use, the shielding plate is first rotated so that its upper surface is parallel to the upper surface of the connecting end, and then the shielding plate is slid so that the limit rod is inserted into the limit hole, and then the connecting rod is rotated to connect the rubber hoop to the limit rod. While sliding, the limit slide rod is pressed downward. When the shielding plate slides to the maximum limit, the limit slide rod is released, and the limit slide rod is inserted into the insertion hole through the resistance spring reset. At this time, the inner wall of the insertion hole is restricted by the side wall of the limit slide rod, so that the sliding of the shielding plate is restricted, thereby increasing the stability of the shielding plate when in use.

[0034] In the present application, when the sliding shield plate releases the connection between the limit rod and the limit hole, the rubber block is also released from the accommodating hole. At this time, the torsion spring is reset, so that the shield plate releases the blocking of the accommodating hole opening, and when the shield plate is rotated to contact the inclined plate through the blocking of the inclined plate, the rotation path of the shield plate is restricted, and the mutual cooperation of the blocking of the inclined plate and the reset of the torsion spring can maintain the rotation angle of the shield plate, so that when the connecting end and the plug-in end are connected, the shield plate drives the part of the ear plate with the plug-in hole to be located above the plug-in end, so that the shield plate does not need to be rotated manually, so that when the connecting end and the plug-in end are plugged in, the plug-in rod can be plugged into the plug-in hole, thereby further increasing the practicality of the device.

[0035] The present application forms a channel on the side plate by passing the guide rod through it. When in use, the inner wall of the channel restricts the side wall of the guide rod so that the guide rod can only slide on the side plate in a straight line direction, and then the mounting plate and the sliding limit rod can only slide on the inserted end in a straight line direction, thereby increasing the stability of the sliding limit rod when sliding. The resistance spring is sleeved on the outer wall of the guide rod. The deformation direction of the resistance spring is also restricted by the restriction of the side wall of the guide rod, thereby increasing the stability of the resistance spring when deforming.

[0036] When the present application is in use, the pushing spring pushes the plug-in block away from the inner cavity, thereby causing the plug-in block to come into contact with the baffle plate, while the sliding of the baffle plate is limited by the sliding limit rod, thereby reducing the gap between the baffle plate and the plug-in block when the baffle plate protects the terminal, further increasing the connection strength between the two, and increasing the protective effect of the device on the terminal.

[0037] The wire and the end wire of the present application have an inner core. When connecting, the inner core of the wire is inserted into the end wire so that the inner cores of the two are connected. After the connection is completed, the threaded sleeve is slid and rotated so that the threaded sleeve and the connecting sleeve are threadedly connected, thereby connecting the wiring harness assembly to the connecting end.

[0038] During the insertion process, the present application first rotates the screw rod so that the screw rod contacts the insertion block, so that when the connecting end and the insertion end are connected, the insertion block will not retract into the inner cavity due to external force, resulting in the possibility of inadequate connection between the connecting end and the insertion end, thereby increasing the practicality of the device.

[0039] The wire of the present application is inserted into the receiving head through the connecting head, so that the wiring harness assembly is connected to the automobile CAN bus, so that the automobile CAN bus can be used normally. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Embodiment 1

[0052] like Figure 1 - Figure 8 As shown, the connector proposed in the first embodiment of the present application includes:

[0053] The plug-in end 1 is connected to the electrical appliance. The plug-in end 1 is provided with a plug-in cavity 101. The plug-in end 1 is electrically connected to the electrical appliance port or circuit board on the car through threads or other means to form a new port. The plug-in cavity 101 is provided with a terminal for receiving. The plug-in end 1 functions as a female connector.

[0054] The connecting end 2 is provided with an inserting block 201 for inserting into the inserting cavity 101. The inserting block 201 is provided with a receiving hole 202 for receiving a terminal. The connecting end 2 and the inserting block 201 form a male connector. When in use, the inserting block 201 is inserted into the inserting cavity 101, so that the terminal in the inserting cavity 101 is connected with the terminal in the receiving hole 202, so that the connector can be used normally.

[0055] The connecting end 2 is provided with a shielding plate 203, and the shielding plates 203 are two in number and are symmetrically and movably installed on both sides of the connecting end 2. Figure 1From the main perspective, the shielding plates 203 are respectively located on the upper and lower sides of the connecting end 2. The shielding plates 203 are used to shield the opening of the receiving hole 202. A connecting piece 3 is installed between the shielding plates 203. The connecting piece 3 is used to connect the two shielding plates 203 so that the movement of the shielding plates 203 at the connecting end 2 is restricted. The shielding plates 203 can slide and rotate on the connecting end 2. When in use, a rubber block is installed on the shielding plate 203. By sliding the shielding plate 203, the rubber block is inserted into the receiving hole 202. When the rubber block After the rubber block is inserted into the receiving hole 202, the inner wall of the receiving hole 202 can also block the rubber block to limit the rotation of the shielding plate 203, thereby increasing the stability of the shielding plate 203 when protecting the terminal. Moreover, the two shielding plates 203 are connected by the connecting member 3, so that even if the shielding plate 203 slides by mistake and the rubber block is disconnected from the receiving hole 202, the two shielding plates 203 are connected to each other at this time and cannot move away from each other, thereby further increasing the stability of the shielding plate 203 when in use.

[0056] The plug-in rod 4 is installed on the plug-in end 1, and the shielding plate 203 is provided with an plug-in hole 5 for accommodating the plug-in rod 4. The shielding plate 203 is rotated so that the plug-in hole 5 can accommodate the plug-in rod 4. When the device needs to be used, the connection between the two shielding plates 203 is released through the cooperation of the connecting member 3, and the shielding plate 203 is slid to separate the rubber block from the accommodating hole 202. At this time, the shielding plate 203 is rotated to release its shielding of the opening of the accommodating hole 202, and the plug-in block 201 is inserted into the plug-in cavity 101;

[0057] The insertion hole 5 is waist-shaped. When the insertion end 1 is connected to the connection end 2, the shielding plate 203 is rotated to drive the insertion hole 5 to approach and accommodate the insertion rod 4. When in use, when the insertion hole 5 is connected to the insertion rod 4, the shielding plate 203 is in an inclined state, such as Figure 1 As shown, when in use, there is an angle between the shielding plate 203 and the insertion rod 4. The insertion rod 4 limits the shielding plate 203, which limits the tendency of the connection end 2 and the insertion end 1 to move away from each other, thereby increasing the stability of the connection between the two.

[0058] When in use, when the connector is transported, the shielding plate 203 plays a protective role. When the connector is put into use, the shielding plate 203 is used through the insertion hole 5 and the insertion rod 4 to play the role of a connecting component, thereby increasing the practicality of the shielding plate 203.

[0059] Compared with the prior art, a baffle plate 203 is installed on the connecting end 2. During transportation, the opening of the accommodating hole 202 is blocked by the baffle plate 203 to protect the terminal, and the movement of the baffle plate 203 is restricted by the cooperation of the connecting piece 3, thereby increasing the stability of the baffle plate 203 during use. When it is needed, the connecting end 2 is inserted into the insertion end 1, and the insertion hole 5 is connected to the insertion rod 4 through the movement of the baffle plate 203, thereby further increasing the connection strength between the connecting end 2 and the insertion end 1, reducing the possibility of separation of the two during use, and increasing the practicality of the device. Embodiment 2

[0060] like Figure 5 and Figure 7 As shown, the second embodiment connects the insertion end 1 and the connection end 2 on the basis of the first embodiment. In the second embodiment, an inclined block 102 is slidably mounted on the insertion end 1 through a connecting spring 103, and a force-bearing inclined surface is provided on the inclined block 102 to Figure 1 From the main perspective, the inclined block 102 is slidably installed on the insertion end 1 in the vertical direction, and the connecting spring 103 forces the inclined block 102 to move away from the top of the insertion end 1;

[0061] The inclined block 102 is connected to the insertion rod 4 so that the insertion rod 4 and the insertion end 1 are slidably matched. The insertion block 201 is equipped with a contact plate 204, and the contact plate 204 is provided with a contact inclined surface parallel to the inclined surface of the inclined block 102, which is parallel to the force-bearing inclined surface. In normal state, the connecting spring 103 makes the insertion rod 4 in a lower position. When the insertion block 201 is inserted into the insertion cavity 101, the shielding plate 203 is rotated to make it tilted, and the shielding plate 203 is rotated to make it tilted. The oblique block 102 is resisted by the resisting plate 204. During the resistance, the resisting inclined surface and the force-bearing inclined surface guide the oblique block 102, so that the insertion rod 4 moves upward. When the shielding plate 203 moves to the top of the insertion end 1, the insertion rod 4 is also inserted into the insertion hole 5 to complete the connection. When in use, it is convenient to connect the insertion rod 4 with the insertion hole 5, so that the connection between the connection end 2 and the insertion end 1 is more stable, and the connection between the insertion rod 4 and the insertion hole 5 is more convenient.

[0062] During the process, the connecting spring 103 has a tendency to reset, so that it applies a force to the inclined block 102 to resist the resistance plate 204. This force is applied to the resistance inclined surface through the force-bearing inclined surface, which will generate a force that separates the connecting end 2 from the insertion end 1. The insertion rod 4 is inserted in the insertion hole 5, which limits the tendency of the two to move away from each other, thereby reducing the gap between the insertion rod 4 in the insertion hole 5, further increasing the strength of the connection between the connecting end 2 and the insertion end 1, and reducing the possibility of the two being separated due to large vibrations when the car is driving.

[0063] like Figure 8As shown, in the second embodiment, a slide groove 6 is provided on the connecting end 2, and a rotation groove 601 is provided at one end of the slide groove 6 away from the connecting end 2. A movable rod 602 is installed on the shielding plate 203, and two parallel planes are provided on the side wall of the movable rod 602. The height of the slide groove 6 is equal to the distance between the two planes, and the diameter of the rotation groove 601 is greater than or equal to the diameter of the movable rod 602. Figure 1 From the main perspective, when the shielding plate 203 blocks the opening of the receiving hole 202, the plane of the movable rod 602 is parallel to the upper surface of the connecting end 2 and fits with the inner wall of the slide groove 6. At this time, the shielding plate 203 cannot rotate and can only slide in the slide groove 6, so that when the shielding plate 203 is released from blocking the opening of the receiving hole 202, it needs to slide first. In this state of the shielding plate 203, the rubber block on it is inserted into the receiving hole 202. If the shielding plate 203 is forcibly rotated directly, it is easy for the rubber block to cause resistance to the inside of the receiving hole 202, causing the receiving hole 202 to deform. Therefore, the rotation of the shielding plate 203 is restricted by the cooperation of the slide groove 6 and the movable rod 602, and the operator is reminded that it is necessary to slide first, which plays a role in preventing mistakes.

[0064] When it is necessary to remove the blocking of the baffle plate 203 on the opening of the accommodating hole 202, first slide the baffle plate 203 in the direction away from the connecting end 2, so that the movable rod 602 slides into the rotating groove 601, and the movable rod 602 can rotate in the rotating groove 601, so that the baffle plate 203 can be rotated at this time. Through the above design, when in use, the restriction of the movable rod 6 by the slide groove 6 further increases the restriction on the rotation of the baffle plate 203, and the cooperation between the slide groove 6 and the movable rod 602 plays a fool-proof role, thereby increasing the practicality of the device.

[0065] like Figure 4 , Figure 6 and Figure 7 As shown, in the second embodiment, the connecting member 3 includes a limiting rod 301 installed on one of the shielding plates 203, and a limiting hole 302 for accommodating the limiting rod 301 is opened on the contact plate 204. Figure 1 From the main perspective, the axis direction of the limiting hole 302 is in the horizontal direction. When in use, when it is necessary to protect the opening of the accommodating hole 202, the shielding plate 203 is rotated to make its upper surface parallel to the upper surface of the connecting end 2, and then the shielding plate 203 is slid so that the limiting rod 301 is slidably inserted into the limiting hole 302, and the rotation of the limiting rod 301 is limited by the inner wall of the limiting hole 302, which further increases the restriction on the rotation of the shielding plate 203. When the shielding plate 203 is subjected to an external force that causes the shielding plate 203 to rotate, the external force is shared by the limiting rod 301, the movable rod 602 and the rubber block, thereby increasing the durability of the device.

[0066] A rotating rod 303 is installed on the other shielding plate 203, and a connecting rod 304 is rotated on the rotating rod 303. A rubber hoop 305 for connecting with the limiting rod 301 is installed on the connecting rod 304. The rubber hoop 305 has an opening, and the opening is smaller than the diameter of the limiting rod 301. When the two shielding plates 203 are slid until the rubber block is inserted into the receiving hole 202, the connecting rod 304 is rotated so that the rubber hoop 305 is close to the limiting rod 301. When the two conflict, the limiting rod 301 is accommodated by the deformation of the rubber hoop 305, so that the rubber hoop 305 is connected to the limiting rod 301, and then the rotation of the other shielding plate 203 can also be limited by the limiting rod 301, which further increases the stability of the shielding plate 203 when protecting the terminal;

[0067] The shielding plate 203 on which the limit rod 301 is installed is provided with an ear plate 306, the insertion hole 5 is provided on the ear plate 306, and a limit sliding rod 308 is slidably installed on the connecting end 2 through a resisting spring 307, so as to Figure 4 From the main perspective, the sliding rod 308 includes a plate body in the horizontal direction and a rod body in the vertical direction. The plate body of the sliding rod 308 is connected to the resistance spring 307. The sliding rod 308 is used to be inserted into the insertion hole 5. Figure 1 From the main perspective, when the shielding plate 203 blocks the opening of the receiving hole 202, the opening of the insertion hole 5 faces the vertical upward direction, and the sliding limit rod 308 slides on the connecting end 2 in the vertical direction;

[0068] When the device is in use, the shielding plate 203 is first rotated so that its upper surface is parallel to the upper surface of the connecting end 2, and then the shielding plate 203 is slid so that the limiting rod 301 is inserted into the limiting hole 302, and then the connecting rod 304 is rotated so that the rubber hoop 305 is connected with the limiting rod 301. While sliding, the limiting slide rod 308 is pressed downward. When the shielding plate 203 slides to the maximum limit, the limiting slide rod 308 is released, and the limiting slide rod 308 is reset by the resistance spring 307 so that the limiting slide rod 308 is inserted into the insertion hole 5. At this time, the side wall of the limiting slide rod 308 limits the inner wall of the insertion hole 5, so that the sliding of the shielding plate 203 is limited, thereby increasing the stability of the shielding plate 203 when in use;

[0069] When the connection end 2 and the insertion end 1 are inserted, the contact plate 204 acts as a driving member to make the insertion rod 4 slide on the insertion end 1. When the shielding plate 203 shields the receiving hole 202, the contact plate 204 cooperates with the limiting hole 302 thereon to form a limiting member, thereby increasing the practicality of the contact plate 204.

[0070] When the limiting rod 301 is connected to the limiting hole 302 on the abutting plate 204, it plays a limiting role. When the rubber hoop 305 is connected to the limiting rod 301, the limiting rod 301 plays a role of a connecting component for connecting the two shielding plates 203, thereby increasing the practicality of the limiting rod 301.

[0071] When the connector needs to be used, the insertion hole 5 is used to connect with the insertion rod 4, increasing the connection strength between the connection end 2 and the insertion end 1; when the shielding plate 203 needs to protect the accommodating hole 202, the insertion hole 5 is connected to the sliding limit rod 308, increasing the stability of the shielding plate 203 during use, so that the insertion hole 5 can be used in different usage scenarios, thereby increasing the practicality of the insertion hole 5. Embodiment 3

[0072] like Figure 1 and Figure 8 As shown, the third embodiment is disclosed on the basis of the second embodiment of the present application. In the third embodiment, a slide plate 7 is slidably installed in the slide groove 6, and the movable rod 602 is rotatably connected to the slide plate 7. A torsion spring 8 is installed between the slide plate 7 and the movable rod 602. An inclined plate 9 is installed on the connecting end 2. The inclined plate 9 is used to limit the rotation range of the shielding plate 203. The torsion spring 8 enables the shielding plate 203 to release the shielding of the opening of the accommodating hole 202. When the sliding shielding plate 203 releases the connection between the limiting rod 301 and the limiting hole 302, the rubber block is also released from the accommodating hole 202. At this time, the torsion spring 8 is reset, so that the shielding plate 203 releases the blocking of the opening of the accommodating hole 202. The opening of the accommodating hole 202 is blocked, and when the blocking plate 203 is rotated to contact the inclined plate 9 through the blocking of the inclined plate 9, the rotation path of the blocking plate 203 is restricted, and the rotation angle of the blocking plate 203 is maintained through the mutual cooperation of the blocking of the inclined plate 9 and the restoration of the torsion spring 8, so that when the connecting end 2 and the plug-in end 1 are connected, the blocking plate 203 drives the part of the ear plate 306 with the plug-in hole 5 to be located above the plug-in end 1, so that the blocking plate 203 does not need to be rotated manually, so that when the connecting end 2 and the plug-in end 1 are plugged in, the plug-in rod 4 can be plugged into the plug-in hole 5, thereby further increasing the practicability of the device.

[0073] In the third embodiment, a side plate 10 is installed on the connection end 2, a guide rod 11 is slidably installed on the side plate 10, a mounting plate 12 connected to the guide rod 11 is slidably installed on the connection end 2, and the sliding limit rod 308 is installed on the mounting plate 12. The guide rod 11 passes through the side plate 10 to form a channel thereon. When in use, the inner wall of the channel restricts the side wall of the guide rod 11 so that the guide rod 11 can only slide on the side plate 10 in a straight line direction, and then the mounting plate 12 and the sliding limit rod 308 can only slide on the connection end 2 in a straight line direction, thereby increasing the stability of the sliding limit rod 308 when sliding;

[0074] The resistance spring 307 is sleeved on the outer wall of the guide rod 11 , and the deformation direction of the resistance spring 307 is also limited by the restriction of the side wall of the guide rod 11 , thereby increasing the stability of the resistance spring 307 during deformation.

[0075] In embodiment three, an inner cavity 13 is opened on the connecting end 2, and the plug-in block 201 is slidably installed in the inner cavity 13. A push spring 14 is installed between the plug-in block 201 and the inner wall of the inner cavity 13. When in use, the push spring 14 pushes the plug-in block 201 away from the inner cavity 13, so that the plug-in block 201 is in conflict with the baffle plate 203, and the sliding of the baffle plate 203 is limited by the sliding limit rod 308, which reduces the gap between the baffle plate 203 and the plug-in block 201 when the baffle plate 203 protects the terminal, further increases the connection strength between the two, and increases the protection effect of the device on the terminal.

[0076] like Fig. 9 As shown, the present application also provides a wiring harness assembly, including the above-mentioned connector, and also includes a wire 15, on which a threaded sleeve 16 is movably installed, and the threaded sleeve 16 can slide and rotate on the wire 15, and an internal thread is provided on the threaded sleeve 16, and an end wire 17 electrically connected to the terminal is installed on the insertion block 201, and a connecting sleeve 18 is provided on the end wire 17, and an external thread is provided on the connecting sleeve 18, and the threaded sleeve 16 is threadedly connected to the connecting sleeve 18, and the wire 15 and the end wire 17 have an inner core, and the inner core is the existing data cable inner core, and the outside of the inner core has a rubber skin, and the wire 15 or the end wire 17 is formed by the inner core and the skin. When connecting, the inner core of the wire 15 is inserted into the end wire 17, so that the inner cores of the two are connected. After the connection is completed, the threaded sleeve 16 is slid and rotated, so that the threaded sleeve 16 is threadedly connected to the connecting sleeve 18, and then the wiring harness assembly is connected to the connecting end 2.

[0077] like Fig. 9 As shown, in some embodiments, an extension plate 19 is installed on the wire 15, and a screw 20 is threadedly connected to the extension plate 19. A through hole 21 for the screw 20 to pass through is opened on the connecting end 2. When inserting, the screw 20 is first rotated so that the screw 20 contacts the insertion block 201. When the connecting end 2 is connected to the insertion end 1, the insertion block 201 will not retract into the inner cavity 13 due to external force, thereby reducing the possibility of inadequate connection between the connecting end 2 and the insertion end 1, thereby increasing the practicality of the device.

[0078] like Fig.10As shown, the present application also provides an automobile CAN bus, which in some embodiments is used to connect with the above-mentioned wiring harness assembly, including a terminal, which can be an electronic product such as a vehicle-mounted computer or a vehicle body operating console, and also includes a receiving head 22 installed on the terminal, and a connector 23 for being plugged into the receiving head 22 is installed on the wire 15. When in use, the wire 15 is plugged into the receiving head 22 through the connector 23, so that the wiring harness assembly is connected to the automobile CAN bus, so that the automobile CAN bus can be used normally.
