Detailed Description

The present application will be described in further detail with reference to fig. 1 to 9.

Examples

Referring to fig. 1 to 2, a connector for a vehicle having waterproof and vibration-proof functions includes a first connector body 1, a second connector body 2, a clip 3, a fixing member 4, and a damper 5.

Referring to fig. 1-2, the first connector body 1 is located on the right side, and is provided with a mating port 11 along the length direction, and a plurality of contacts are provided on the inner wall of the mating port 11. The fixing groove 12 is formed near the upper end and the lower end of the opposite connector 11, the fixing groove 12 comprises a first sliding groove 121 communicated with the outside and a second sliding groove 122 positioned in the first connector main body 1, the first sliding groove 121 and the second sliding groove 122 are communicated with each other, and the opening of the first sliding groove 121 is a round hole.

Referring to fig. 1 to 3, the second connector body 2 is positioned on the left side, a terminal 21 that mates with the mating port 11 of the first connector body 1 is provided, a fixing block 22 is provided near the periphery of the terminal 21, the fixing block 22 is cylindrical, and the cylindrical fixing block 22 mates with the first chute 121 in a plugging manner. After the terminal 21 is inserted into the interface 11, the contact and the terminal 21 can be electrically connected. The terminal 21 is made of an elastic conductor and has a certain elastic compression amount. Therefore, even if the vehicle runs on a bumpy road to generate vibration, the contact point can be accurately and stably contacted, the stability of the output of signals and a power supply is realized, and the use reliability and the practicability of the equipment are improved.

Referring to fig. 1 and 3, the clip 3 is provided on the fixed block 22, and the clip 3 is slidable along the extending direction of the second chute 122. The clamping piece 3 is hinged with the fixed block 22, a friction piece 23 is arranged at the hinged position of the clamping piece 3 and the fixed block 22, and the friction piece 23 is used for avoiding autorotation around the hinged position when the clamping piece 3 is not acted by external force. When the vehicle shakes and causes the joint of the first connector body 1 and the second connector body 2 to shake, the clamping piece 3 can relatively slide in the second sliding groove 122 relative to the fixed block 22 due to the fact that the clamping piece 3 is hinged with the fixed block 22. When the emergency occurs and a severe shake occurs between the first connector body 1 and the second connector body 2, the fixing block 22 cannot be separated from the first chute 121 at the first time due to the clamping piece 3, so that the response time of signal interruption of the first connector body 1 and the second connector body 2 is increased.

Referring to fig. 3 and 4, the friction member 23 includes damping fins disposed in pairs, and the damping fins are disposed at the hinge of the clamping member 3 and the fixed block 22, and are mainly used for slowing down the rotation of the clamping member 3 at the hinge. Since the vehicle may encounter jolt vibrations during travel, the components of the connector are susceptible to relative movement. The existence of the damping fin can slow down the rotation speed of the clamping piece 3 by providing certain damping, and the rotation caused by the self gravity of the clamping piece 3 is prevented. The damping fin is made of polyurethane, and the polyurethane is a high-strength and wear-resistant plastic material, has good elasticity and durability, and is suitable for occasions requiring frequent movement in the embodiment.

Referring to fig. 3 to 4, in the present embodiment, the clamping member 3 includes a nut 31 and a ball stud 32, two baffles 221 are disposed at the right end of the fixing block 22, a damping fin is disposed between the two baffles 221, and a rotation column is disposed between the two oppositely disposed baffles 221. The nut 31 is hinged with the baffle 221 at the left end of the fixed block 22, and the side wall of the nut 31 abuts against the damping fin when the nut 31 rotates relative to the rotating column. One end of the ball stud 32 away from the ball thereof is in threaded fit with the nut 31, and the ball of the ball stud 32 can slide along the extending direction of the second sliding groove 122 when abutting against the inner wall of the second sliding groove 122. The ball stud 32 is detachably connected with the nut 31 through threads, so that ball studs 32 with different sizes and materials can be selected, and the adaptability is improved. The damping fin can also prevent the nut 31 and the ball stud 32 from rotating due to self gravity before passing through the first chute 121, so that the ball head can be conveniently and smoothly abutted against the inner wall of the second chute 122. In addition, the damping fin can also increase the resistance of the ball stud 32 to the rotation of the fixed block 22 when the vehicle shakes, so as to avoid the fixed block 22 from being quickly separated from the first chute 121, further increase the contact time between the terminal 21 and the interface 11, and avoid the break contact caused by the shaking of the vehicle.

Referring to fig. 3, the second slide groove 122 includes a smooth abutting section 1221 and a sliding section 1222 having a curvature, the abutting section 1221 is smoothly connected to the sliding section 1222, the sliding section 1222 has an involute shape in an extending direction, and when the second connector body 2 approaches the first connector body 1, the ball of the ball stud 32 abuts against the abutting section 1221 and can slide along the sliding section 1222. When the first connector body 1 and the second connector body 2 are connected, the first connector body 1 is held stationary, and a right pushing force is applied to the second connector body 2. So that the fixing block 22 is inserted into the first sliding groove 121, and when the fixing block 22 is inserted into the first sliding groove 121, the ball of the ball stud 32 moves into the second sliding groove 122. Then, the ball of the ball stud 32 contacts the abutting section 1221 under the action of the right pushing force, and the ball of the ball stud 32 is subjected to the reaction force towards the left and the lower direction due to the reverse acting force of the abutting section 1221, so that the ball stud 32 is driven to rotate around the hinge. The involute second sliding groove 122 is helpful to reduce the resistance of the locking piece 3 rotating and sliding around the hinge point, thereby improving the stability of the locking piece 3 in the rotating process and reducing the vibration sensitivity of the connector in the running process of the vehicle. In addition, the involute design allows the ball stud 32 to be gradually moved from parallel to the fixed block 22 and then gradually perpendicular to the fixed block 22 (in conjunction with fig. 5 and 6) as the fixed block 22 is inserted, facilitating the subsequent fixing of the ball by the fixing assembly 4.

Referring to fig. 3 and 7, the fixing assembly 4 is disposed in the first connector body 1, and the fixing assembly 4 can fix the clip 3 and the first connector body 1 when the terminal 21 (combined with fig. 1) is completely inserted into the first sliding groove 121. The fixing assembly 4 includes a fixing base 41, a clamping airbag 42, a first connecting air tube 43, and a sealing member 44. The fixing base 41 is disposed in the second chute 122 of the first connector body 1, and the fixing base 41 is L-shaped. The clamping airbag 42 is fixedly connected with the bottom of the fixing seat 41, the clamping airbag 42 is positioned at the bottom of the fixing seat 41 when being inflated, and the ball head of the ball stud 32 can be clamped after the clamping airbag 42 is inflated. The clamping airbag 42 is a prefabricated member, and can be attached to and clamp the ball head after inflation. The first connecting air pipe 43 is embedded in the first connector main body 1, one end of the first connecting air pipe 43 is communicated with the clamping air bag 42, the other end of the first connecting air pipe 43 is communicated with the outside, one end, close to the outside, of the first connecting air pipe 43 is provided with an air charging valve 431 (combined with fig. 8), and the air charging valve 431 is used for controlling the opening and closing of the first connecting air pipe 43. The inflation valve 431 employs a SRS miniature solenoid valve that facilitates inflation of the clamp airbag 42.

Further, after the clamp airbag 42 is inflated, the temperature of the terminal 21 gradually increases as the signal transmission of the sensor operates during the running of the vehicle. The temperature of the terminal 21 is increased to exchange heat to the first connector body 1 and then to the clamping air bag 42, and the clamping air bag 42 transfers heat to the air in the clamping air bag 42, so that the clamping air bag 42 is further expanded, the clamping ball head is clamped more tightly, and the fixing block 22 is prevented from falling out of the first sliding groove 121.

Referring to fig. 1 and 8, the sealing member 44 includes a second connection gas pipe 441 and an annular gas bag 442, the second connection gas pipe 441 is embedded in the interior of the first connector body 1, and the second connection gas pipe 441 communicates with the first connection gas pipe 43. The annular air bag 442 is fixedly adhered to one end of the first connector body 1 near the terminal 21, and is communicated with one end of the second connecting air tube 441 far away from the first connecting air tube 43, and the terminal 21 can be inserted into the opposite port 11 through the annular air bag 442. The sealing member 44 is provided at the left side of the first connector body 1, and the sealing member 44 can gradually seal the junction of the terminal 21 and the first connector body 1 as the clamp airbag 42 expands.

Referring to fig. 4, a damping member 5 is disposed in the first chute 121, and the damping member 5 is configured to dampen the impact of vibration on the fixed block 22. The damping member 5 includes a plurality of elastic columns 51, one ends of the plurality of elastic columns 51 are fixedly connected to the inner wall of the first chute 121 at intervals, and a plurality of coil springs 52 are fixedly connected to the first connector body 1 and respectively sleeved on the elastic columns 51. When jolting or vibration is received during running of the vehicle, the vibration is transmitted to the first chute 121 through the first connector body 1. The elastic column 51 is fixed on the inner wall of the chute, and can elastically deform, absorb and slow down vibration. One end of the elastic columns 51 is fixed on the inner wall of the chute, so that the damping member has the function of multi-point support, and is helpful to more uniformly disperse vibration force, and the stability of the damping member is increased. The linkage design of the elastic post 51 and the coil spring 52 can provide a greater vibration absorbing capability together.

The implementation principle is as follows:

The terminal 21 and the fixing block 22 on the second connector body 2 are first aligned with the opposite port 11 and the first slide groove 121, respectively, and then the terminal 21 is inserted into the opposite port 11. The fixing block 22 gradually drives the ball stud to slide into the second sliding groove 122 from the first sliding groove 121 due to the pushing force. During this time, the ball stud 32 does not rotate due to its own weight due to the friction member 23. After the ball of the ball stud 32 abuts against the abutment 1221, the ball stud 32 is driven to rotate on the second sliding groove 122 around the hinge by the reaction force, and finally the ball slides onto the fixing seat 41. Then inflation is started, and an inflation device such as an air pump is selected to inflate the inflation valve 431 and the gas is delivered from the first connecting gas tube 43 into the clamp balloon 42 and the annular balloon 442. The holding balloon 42 and the annular balloon 442 are inflated separately, wherein the holding balloon 42 is inflated and holds the ball head, preventing the fixing block 22 from falling out of the fixing groove 12. Even if the ball stud 32 starts to rotate in the second chute 122 due to shaking of the fixed block 22, the first time of the fixed block 22 cannot be completely separated from the first chute 121, so that the contact time of the terminal 21 and the contact is increased, signal interruption caused by direct falling is avoided, and a certain early warning time is provided. While the clamping air bag 42 is inflated, not only the clamping of the ball head but also the waterproof sealing function can be realized. The second connection pipe enables the annular air bag 442 to expand and seal the connection point on the terminal 21, thereby achieving a waterproof function. In addition, since the grip airbag 42 has a certain elasticity, the stability of the connectors in bumpy running of the vehicle is increased, and the risk of falling off between the connectors due to rattling is reduced.
