Description

Technical Field

[0001] The invention relates to the technical field of signal line-to-board connectors, in particular to a high-vibration-resistant vehicle signal line-to-board connector. Background Art

[0002] The automotive signal line-to-board connector is responsible for accurately and reliably transmitting the signals of various sensors, controllers and other electronic devices of the vehicle. The high vibration resistance automotive signal line-to-board connector adopts special materials and structural design to ensure that it can maintain good electrical connection performance under harsh conditions such as vibration, shock and temperature changes.

[0003] The patent with patent number CN216450888U discloses a high vibration resistance automotive signal line-to-board connector, including a line end connector and a board end connector. The line end connector includes a line end body, a line end terminal and a secondary lock. The line end terminal includes a terminal convex bump, a terminal tongue and a terminal clamping position. The line end body includes a buckle and an inner lock. The buckle cooperates with the lock groove of the secondary lock. The inner lock cooperates with the board end connector. The terminal clamping position cooperates with the main body tongue. The secondary lock includes a main body tongue and a lock groove. The main body tongue cooperates with the terminal clamping position of the line end terminal. The lock groove cooperates with the buckle. The terminal convex bump is used to contact the pin needle in the board end connector. After the pin needle is inserted into the terminal convex bump, it contacts through friction, and the contact is more reliable and stable. The terminal tongue is also used to contact the pin needle. When the line end body is connected to the board end connector, a four-point contact, i.e., a bilateral spring structure, is formed, which increases the contact elasticity, can contact the pin needle more firmly, and improves the vibration resistance of the connector combination.

[0032] The side where the two convex plates 9 are away from each other is provided with an anti-vibration component 601, and the anti-vibration component 601 includes two slide bars 10, and the two slide bars 10 are respectively fixed on the side where the two convex plates 9 are away from each other, and the right sides of the two slide bars 10 are provided with sliding holes, and the outer walls of the two slide bars 10 are slidably mounted with hole frames 11, and the sides where the two hole frames 11 are close to each other are fixedly connected to the inner walls of the two grooves of the female plug block 1, and the left sides of the two hole frames 11 are fixed with springs 12, and the two springs 12 are respectively in a compressed state, and the two springs 12 are respectively sleeved on the outer walls of the two slide bars 10, and the ends of the two springs 12 away from the two hole frames 11 are fixed with round blocks 13, and the right sides of the two round blocks 13 are fixedly connected to the left ends of the two slide bars 10. Under the elastic force of the springs 12, the convex plate 9 is tightly pressed against the slide groove bar 6, so that the female end 5 is firmly inserted into the jack of the female plug block 1, so as to avoid the vibration separation of the connector during the intense driving of the car and cause the vehicle signal to be disconnected;

[0033] The inner wall of the sliding hole of the two sliding bars 10 is provided with an anti-deviation component 602, and the anti-deviation component 602 includes a U-shaped bar 14, and the U-shaped bar 14 is slidably installed on the inner wall of the sliding hole of the two sliding bars 10, and two springs 15 are fixed on the left side of the U-shaped bar 14, and one end of the two springs 15 away from the U-shaped bar 14 is fixedly connected to the inner wall of the sliding hole of the two sliding bars 10, and two ring frames 16 are fixed on the outer wall of the U-shaped bar 14, and the two ring frames 16 are located on the right side of the sub-block 4, and a support plate 17 is fixed on the left side of the two ring frames 16, and the right side of the sub-block 4 is on the movement trajectory of the support plate 17, and the support plate 17 is tightly attached to the right side of the sub-block 4, so that the female end 5 on the sub-block 4 will not deviate when the sub-block 4 moves to the left, so as to avoid the slow connection of the jack caused by the movement deviation of the sub-block 4 during the connection of the connector.

[0034] When in use, the staff member picks up the female plug block 1 with his left hand and the sub-block 4 with his right hand, moves the sub-block 4 to the left, the sub-block 4 drives the female end 5 to move to the left, the female end 5 drives the cable 3 to move to the left, and the female end 5 is inserted into the socket of the female plug block 1. In the process of the female end 5 moving to the left, the female end 5 is sleeved on the sub-end 2 and slides to the left, so that the right side of the sub-end 2 contacts the inside of the female end 5, so that the two rows of cables 3 are connected. Due to the intense driving of the car, the connector in the car is prone to vibration and separation. When connecting and installing the cables 3, the groove of the sub-block 4 supports the slide bar 6, and the slide bar 6 supports the convex plate 9. At the same time, the female plug block 1 supports the hole frame 11. The staff member releases the sub-block 4, and the spring 12 compressed on the hole frame 11 begins to stretch. The elastic force of the spring 12 drives the round block 13 to move to the left. The round block 13 drives the slide bar 10 to move to the left, and the slide bar 10 slides to the left in the hole frame 11. The slide bar 10 drives the convex plate 9 to move to the left, and the convex plate 9 presses against the slide groove bar 6 to move to the left. The slide groove bar 6 drives the sub-block 4 to move to the left, and the sub-block 4 drives the female end 5 to move to the left. The female end 5 is quickly inserted into the socket of the female plug block 1, so that the cable 3 is quickly connected. During the intense driving of the car, the car produces strong vibrations, and the vibrations generated by the car are transmitted to the female plug block 1 and the sub-block 4. Under the elastic force of the spring 12, the convex plate 9 is tightly pressed against the slide groove bar 6, so that the female end 5 is firmly inserted into the socket of the female plug block 1, preventing the connector from vibrating and separating during the intense driving of the car, thereby avoiding the problem of disconnection of the vehicle signal caused by the vibration separation of the connector during the intense driving of the car.

[0035] While the round block 13 drives the slide bar 10 to move to the left, the slide bar 10 drives the spring 2 15 to move to the left, the spring 2 15 is stretched, the spring 2 15 drives the U-shaped rod 14 to move to the left, the U-shaped rod 14 drives the ring frame 16 to move to the left, and the ring frame 16 drives the support plate 17 to move to the left. Under the elastic force of the spring 2 15, the support plate 17 is tightly attached to the right side of the sub-block 4, so that the female end 5 on the sub-block 4 will not shift during the movement of the sub-block 4 to prevent the sub-block 4 from moving and shifting during the connection of the connector, thereby avoiding the problem of slow connection of the jack caused by the movement and shift of the sub-block 4 during the connection of the connector.

[0036] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, a line dividing device 7 is arranged on the left side of the two round blocks 13, and the line dividing device 7 includes a horizontal block 71, a rubber plate 72, four L-shaped short plates 73 and two tooth blocks 74. The horizontal block 71 is fixed on the left side of the two round blocks 13, the rubber plate 72 is fixed on the left side of the horizontal block 71, the four L-shaped short plates 73 are respectively fixed on the top surface and the bottom surface of the horizontal block 71 in groups of two, and the two tooth blocks 74 are respectively fixed on the opposite side of the four L-shaped short plates 73.

The rubber plate 72 separates the two rows of cables 3. When the tooth block 74 moves to the left, the tooth gaps of the tooth block 74 comb the two rows of cables 3 apart, so that the two rows of cables 3 will not be entangled together, so as to avoid the two rows of cables 3 being entangled together during the connection and installation of the connector, causing the cables 3 on the connector to be bent and damaged.

[0037] The line dividing device 7 also includes a plurality of square plates 75, a plurality of spring sheets 76 and a plurality of semi-arc rubber pads 77. The plurality of square plates 75 are respectively fixed on the inner walls of the tooth gaps of the two tooth blocks 74.

The two rubber strips 84 are respectively located above and below the two rows of cables 3, and the two rubber strips 84 are on the movement trajectory of the two cross plates 83. The cross plates 83 contact the rubber strips 84. Under the limit of the rubber strips 84, the cross block 71 will not contact the female plug-in block 1, so that when the staff unplugs the connector for maintenance, the cross block 71 will not hit the female plug-in block 1, so as to avoid the cross block 71 hitting the female plug-in block 1 during the separation process of the connector, causing the connector to be damaged by collision.

[0039] The anti-knock device 8 also includes four L-shaped connecting plates 85, four round-shaped boxes 86 and four sponge blocks 87. The four L-shaped connecting plates 85 are respectively fixed on the front and back sides of the two U-shaped frames 81, and the four round-shaped boxes 86 are all fixed on the right sides of the four L-shaped connecting plates 85. The four sponge blocks 87 are all fixedly installed on the inner walls of the four round-shaped boxes 86. The four left sides of the female plug 1 are on the movement trajectories of the four sponge blocks 87. The sponge blocks 87 will contact the palms of the maintenance personnel, reducing the maintenance personnel's palms from being pinched by the U-shaped frame 81 and the female plug 1, and avoiding the U-shaped frame 81 and the female plug 1 from pinching the maintenance personnel's palms during the separation process of the connector.

[0040] When the elastic force of spring 12 drives the round block 13 to move to the left, the round block 13 drives the cross block 71 to move to the left, and the cross block 71 drives the rubber plate 72 to move to the left. When the rubber plate 72 moves to the left, the rubber plate 72 separates the two rows of cables 3. At the same time, the cross block 71 drives the L-shaped short plate 73 to move to the left, and the L-shaped short plate 73 drives the tooth block 74 to move to the left, so that when the tooth block 74 moves to the left, the teeth of the tooth block 74 comb the two rows of cables 3 apart, so that the two rows of cables 3 will not be entangled together, preventing the two rows of cables 3 from being entangled together during the connection process of the connector, thereby avoiding the problem of the two rows of cables 3 being entangled together during the connection and installation of the connector, causing the cables 3 on the connector to be bent and damaged.

[0041] While the L-shaped short plate 73 drives the tooth block 74 to move leftward, the tooth block 74 drives the square plate 75 to move leftward, the square plate 75 drives the spring sheet 76 to move leftward, and the spring sheet 76 drives the semi-arc rubber pad 77 to move leftward, so that the semi-arc rubber pad 77 slides leftward on the two rows of cables 3, so that the surface of the cables 3 on the connector will not contact the edge of the tooth gap of the tooth block 74, thereby preventing the edge of the tooth gap of the tooth block 74 from scratching the skin of the cables 3 during the connection process of the connector, thereby avoiding the problem of damage to the connector caused by damage to the skin of the cables 3 during the connection and installation process.

[0042] When the car is being overhauled, the connector needs to be separated for overhaul. At this time, the staff member picks up the female plug block 1 with his left hand and pulls the sub-block 4 with his right hand. The sub-block 4 drives the female end 5 to move to the right.

In the process of the cross plate 83 moving to the rightward, the cross plate 83 contacts the rubber strip 84. Under the limit of the rubber strip 84, the cross block 71 will not contact the female plug block 1, so that when the staff unplugs the connector for maintenance, the cross block 71 will not hit the female plug block 1, thereby preventing the cross block 71 from hitting the female plug block 1 when the connector is separated for maintenance, thereby avoiding the problem of the cross block 71 hitting the female plug block 1 during the separation process of the connector, causing the connector to be damaged by the bump.

[0043] While the tooth block 74 drives the U-shaped frame 81 to move to the right, the U-shaped frame 81 drives the L-shaped connecting plate 85 to move to the right, the L-shaped connecting plate 85 drives the circular box 86 to move to the right, and the circular box 86 drives the sponge block 87 to move to the right. When the staff pulls the sub-block 4 hard to move, the sponge block 87 will contact the palm of the maintenance personnel, reducing the maintenance personnel's palm from being pinched by the U-shaped frame 81 and the female plug block 1, thereby avoiding the problem of the maintenance personnel's palm being pinched by the U-shaped frame 81 and the female plug block 1 during the separation process of the connector.
