Abstract
Description
Technical Field
[0001] The present invention relates to the field of automobile technology, and in particular to an electric connector and a vehicle. Background Art
[0002] In current MPV and other vehicle models, an elastic electrical connector is generally required to be provided on the sliding door. When the sliding door is closed, the electrical connector is connected to the circuit on the vehicle body. In the current structure, the electrical connector generally provides a retractable copper rod as a contact. A spring is mounted on the copper rod and connected to the base through the spring. In this structure, the spring can only withstand the force along the expansion and contraction direction of the copper rod. When the copper rod is subjected to an external force with an angle, the copper rod will tend to deflect under the action of the tangential component of the external force, and directly transmit the tangential component to the mounting seat on which the copper rod is installed. Long-term or excessive tangential component force will cause the mounting seat to break, thereby destroying the integrity of the entire structure, and ultimately causing the conduction function of the electrical connector to be lost, seriously affecting the reliability and safety of vehicle use.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0022] In order to reduce the risk of fracture of the mounting seat 100 of the electrical connector on the sliding door, the technical solution proposes an electrical connector, which is used for the sliding door, comprising: The mounting base 100 is provided on the sliding door, and the mounting base 100 is provided with a first mounting hole 110; The elastic member 200 is disposed in the first mounting hole 110 and connected to the mounting seat 100; One end of the conductive component 300 extends into the first mounting hole 110 and abuts against the elastic member 200 . The conductive component 300 is clearance-matched with the first mounting hole 110 and slides along the axial direction of the first mounting hole 110 .
[0023] like Figure 1 and Figure 2 In one embodiment of the present invention, the electrical connector includes a mounting base 100, which is mounted on the sliding door. The mounting base 100 has a mating end surface exposed to the outside of the sliding door, and a first mounting hole 110 is provided on the mating end surface. An elastic member 200 is provided in the first mounting hole 110. The elastic member 200 can be a compression spring. One end of the elastic member 200 can be fixed to the mounting base 100, and the other end extends toward one side of the mating end surface. In addition, the electrical connector also includes a conductive component 300, which can be a conductive column such as a copper rod. The conductive component 300 is used to connect with the contact on the vehicle body to realize the conduction between the sliding door circuit and the vehicle body circuit. One end of the conductive component 300 can be slidably inserted into the first mounting hole 110, and the conductive component 300 can slide along the axial direction of the first mounting hole 110. The end of the conductive component 300 extending into the first mounting hole 110 can abut against the elastic member 200. In addition, the conductive component 300 and the first mounting hole 110 are clearance-matched, so that the conductive component 300 can swing in the first mounting hole 110, and the specific swing amplitude can be flexibly adjusted according to needs.
[0024] The working process of the electrical connector will be described below: when the sliding door is closed, the conductive component 300 docks with the contact on the vehicle body. At the moment of docking, the contact will apply an impact force to the conductive component 300; if the direction of the impact force is parallel to the axial direction of the first mounting hole 110, the conductive component 300 can slide into the first mounting hole 110 under the action of the impact force and compress the elastic member 200, and the elastic member 200 always gives the conductive component 300 a reverse force toward the contact side, so that the conductive component 300 and the contact can be stably in contact; however, if the impact force forms a certain angle with the axial direction of the first mounting hole 110, the tangential component of the impact force will drive the conductive component 300 to have a tendency to swing laterally. The first mounting hole 110 is a clearance fit, and the conductive component 300 has a certain swinging space in the first mounting hole 110, so the conductive component 300 can swing first. When the conductive component 300 swings, since one end of the conductive component 300 abuts against the elastic member 200, the conductive component 300 can drive the elastic member 200 to undergo elastic deformation. At this time, part of the impact force can be transmitted to the elastic member 200 for absorption through the conductive component 300, thereby reducing the impact force of the conductive component 300 subsequently transmitted to the mounting seat 100 through the inner wall of the first mounting hole 110, thereby reducing the risk of the mounting seat 100 being fractured due to force, thereby improving the safety and reliability of the use of the electrical connector, and also helping to ensure the reliability and safety of the vehicle.
[0025] like Figure 1 In one embodiment of the present invention, the conductive component 300 includes: The sliding inner core 310 has one end that is slidably disposed in the first mounting hole 110 and abuts against the elastic member 200. The sliding inner core 310 and the first mounting hole 110 are clearance-matched. The sliding inner core 310 is provided with a second mounting hole that is communicated with the first mounting hole 110. One end of the conductor 320 is slidably inserted into the second mounting hole and abuts against the elastic member 200 , and the conductor 320 is loosely matched with the second mounting hole.
[0026] In the present embodiment, the conductive component 300 is designed as a two-stage telescopic structure, and the conductive component 300 includes a sliding inner core 310 and a conductor 320. The sliding inner core 310 is a cylindrical structure. One end of the sliding inner core 310 can be slidably inserted into the first mounting hole 110 and abut against the elastic member 200, and the other end is exposed outside the first mounting hole 110. There is a clearance fit between the sliding inner core 310 and the first mounting hole 110. A second mounting hole is provided on the sliding inner core 310. The second mounting hole is coaxially arranged with the first mounting hole 110 and is connected to the first mounting hole 110. One end of the conductor 320 can be slidably inserted into the second mounting hole and abut against the elastic member 200, and the other end is exposed outside the second mounting hole. There is also a clearance fit between the conductor 320 and the second mounting hole, that is, the sliding inner core 310 is in the first mounting hole. 110 has a certain swing space, and the conductor 320 has a certain swing space in the second mounting hole; when the sliding door is closed, the conductor 320 first contacts the contact on the vehicle body, and the impact force is first transmitted to the conductor 320. The conductor 320 can swing in the second mounting hole and compress the elastic member 200 to absorb part of the impact. Then the conductor 320 drives the sliding inner core 310 to swing in the first mounting hole 110 to absorb another part of the impact. In this way, the impact effect can be absorbed by the conductor 320 and the sliding inner core 310 in two stages, which can further reduce the impact finally transmitted to the mounting seat 100, thereby further reducing the risk of the mounting seat 100 being fractured by force; in addition, since the sliding inner core 310 partially wraps the conductor 320, the sliding inner core 310 can also provide protection for the conductor 320, further improving the reliability of the use of the electrical connector.
[0027] like Figure 1In one embodiment of the present invention, the electrical connector further comprises a support member 400 . The support member 400 is disposed on a side of the elastic member 200 close to the conductor 320 . The conductor 320 and the sliding inner core 310 abut against the support member 400 . In this embodiment, the support member 400 can be a plate-like structure, the elastic member 200 abuts against one end surface of the support member 400, and the conductor 320 and the sliding inner core 310 abut against the other end surface of the support member 400. The external forces acting on the conductor 320 and the sliding inner core 310 can be transmitted to the elastic member 200 through the support member 400, thereby ensuring that the elastic member 200 can fully absorb the impact transmitted from the conductor 320 and the sliding inner core 310, thereby ensuring the protection effect on the mounting seat 100. In addition, the support member 400 and the conductor 320 and the sliding inner core 310 can be in surface contact, thereby reducing the concentration of the force acting on the conductor 320 and the sliding inner core 310 by the elastic member 200, preventing the conductor 320 and the sliding inner core 310 from being damaged due to excessive local force, thereby improving the reliability of the electrical connector. In addition, the support member 400 in this solution can be made of conductive materials such as copper. In this way, by connecting a wire to the support member 400, an electrical signal can be easily transmitted from the support member 400 to the conductor 320 or from the conductor 320 to the support member 400.
[0028] like Figure 2 In one embodiment of the present invention, a first limiting groove 410 is provided on the side of the support member 400 facing the elastic member 200, and one end of the elastic member 200 is embedded in the first limiting groove 410. The limiting groove can limit the movement range of the elastic member 200 relative to the support member 400 in the radial direction, thereby preventing the elastic member 200 from deflecting and becoming unstable in the radial direction, ensuring that the elastic member 200 can stably apply an elastic force along the axial direction of the first mounting hole 110 to the elastic member 200 during the sliding process of the conductive component 300, thereby ensuring the reliability and stability of the use of the electrical connector. Similarly, in another embodiment of the present invention, a second limiting groove 311 is provided at one end of the sliding inner core 310 toward the support member 400, and the support member 400 is embedded in the second limiting groove 311; the radial displacement of the support member 400 will be limited by the second limiting groove 311, which can also prevent the support member 400 from being offset from the conductor 320 or the sliding inner core 310, thereby ensuring that the impact force can be stably transmitted to the elastic member 200 through the support member 400, and also ensuring the reliability and stability of the use of the electrical connector.
[0029] like Figure 2In one embodiment of the present invention, the support member 400 is provided with a positioning hole, and the conductor 320 is provided with a positioning body 321 protruding toward one end of the support member 400, and the positioning body 321 is plugged into the positioning hole. In this embodiment, the positioning hole can be set at the center of the support member 400, and when the positioning body 321 is inserted into the positioning hole, the conductor 320 and the support member 400 can be mutually limited, so that the conductor 320 can always have good contact with the support member 400 during deflection, thereby reducing the loss of the electrical signal transmitted between the conductor 320 and the support body, and is also conducive to improving the conductive performance and signal transmission capacity of the electrical connector; in addition, in another embodiment of the present invention, the support member 400 and the conductor 320 can be fixedly connected, specifically, the positioning body 321 can be inserted into the positioning hole and riveted and fixed, so that the support body and the conductor 320 can be regarded as one body, and the support body will move synchronously with the conductor 320, which can further ensure the stability of the electrical signal transmission between the two, and further improve the reliability of the use of the electrical connector.
[0030] like Figure 1 In one embodiment of the present invention, a first limiting body 120 is protruded from one end of the first mounting hole 110 away from the elastic member 200, and a second limiting body 312 is protruded from the side wall of the sliding inner core 310 close to the elastic member 200. The second limiting body 312 abuts against the first limiting body 120 to limit the length of the sliding inner core 310 extending out of the first mounting hole 110; wherein the first limiting body 120 can be integrally formed on the inner wall of the first mounting hole 110, and the second limiting body 312 can be integrally formed on the outer peripheral wall of the sliding inner core 310. When the sliding inner core 310 slides away from the elastic member 200, the second limiting body 312 will approach and eventually abut against the first limiting body 120. At this time, the first limiting body 120 can limit the sliding inner core 310 from continuing to slide, preventing the sliding inner core 310 from detaching from the first mounting hole 110, thereby improving the reliability of the use of the electrical connector. In addition, since the first limiting body 120 and the second limiting body 312 are integrally formed on other components, this can simplify the assembly process and reduce the number of parts, thereby reducing the processing cost of the electrical connector and improving economy.
[0031] In one embodiment of the present invention, the sliding inner core 310 is made of plastic. Taking advantage of the lower elastic modulus of plastic than that of metal, the sliding inner core 310 can use the elastic surface to absorb part of the force when subjected to tangential force, thereby further reducing the force acting on the mounting seat 100 and reducing the risk of damage to the mounting seat 100. In addition, the sliding inner core 310 can be made of a plastic material with self-lubricating properties such as nylon, which can reduce the friction between the sliding inner core 310 and the mounting seat 100 and the friction between the conductor 320 and the sliding inner core 310, thereby reducing wear and tear, which is beneficial to extending the service life of the electrical connector.
[0032] In another embodiment of the present invention, a rounded corner is provided at one end of the sliding inner core 310 away from the elastic member 200, which can reduce the concentration of local force when the edge of the sliding inner core 310 contacts the electrical connector on the opposite side, which is beneficial to reducing the wear of the sliding inner core 310. Similarly, a rounded corner is provided at one end of the conductor 320 away from the elastic member 200, which can also reduce the wear of the conductor 320 and extend the service life of the electrical connector.
[0033] The present invention also proposes a vehicle, which includes a body and a sliding door arranged on the body, and an electrical connector is arranged on the sliding door. The electrical connector is used to connect the electrical components on the sliding door with the body circuit. The specific structure of the electrical connector refers to the above-mentioned embodiment. Since the vehicle adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.
[0034] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
