The invention provides an automobile high-speed connector which is mainly suitable for high-speed transmission of automobile signal data.
In an embodiment of the present invention, referring to fig. 1 to 3 in combination with fig. 7, the automotive high-speed connector 1 includes:
a connection wire 60, wherein one end of a wire 630 of the connection wire 60 is connected with a connection terminal 50;
a terminal block 30 having a terminal hole 310 corresponding to the terminal 50, wherein the terminal 50 is inserted into the terminal hole 310;
the limiting piece 40 is sleeved on the lead 630, a limiting welt 410 extending towards the terminal seat 30 is arranged on the limiting piece, and the limiting welt 410 is attached to the outer peripheral surface of the terminal seat 30; and
the shielding main body 20 is provided with a receiving through hole 210, the terminal block 30 and the limiting member 40 are inserted into the receiving through hole 210 from one end of the receiving through hole 210, and the limiting flange 410 is clamped between the receiving through hole 210 and the outer peripheral surface of the terminal block 30.
Specifically, the shielding main body 20 is generally installed in the housing 10 of the high-speed connector 1 of the automobile, and the shielding main body 20 can be fixedly installed with the housing 10 through a plugging or buckling structure. The terminal 50 connected with the connecting wire 60 is installed and fixed in the terminal seat 30, the limiting piece 40 is sleeved on the conducting wire 630 of the connecting wire 60, when the automobile high-speed connector 1 is assembled, the terminal seat 30 is inserted into the accommodating through hole 210 of the shielding main body piece 20, then the limiting piece 40 is installed in the accommodating through hole 210, and the limiting welt 410 of the limiting piece 40 is clamped between the hole wall surface of the accommodating through hole 210 and the outer peripheral surface of the terminal seat 30, so that the fit clearance between the accommodating through hole 210 and the terminal seat 30 is effectively reduced through the limiting welt 410, and the fixing effect of the terminal seat 30 in the accommodating through hole 210 is enhanced. When the automotive high-speed connector 1 is in plug-in fit with other equipment, the wiring terminal 50 is in plug-in fit with a wiring terminal on the other equipment, at this time, the wiring terminal 50 is elastically deformed during plug-in, the wiring terminal 50 is located in the terminal hole 310, the deformed wiring terminal 50 is still limited in the terminal hole 310, and further, the deformed wiring terminal 50 can be effectively prevented from being in contact with the shielding main body piece 20, the influence of the shielding main body piece 20 on a data signal of the wiring terminal 20 is avoided, and the stability of data signal transmission is ensured.
It should be noted that, referring to fig. 2, the connection wire 60 includes a plurality of wires 630 and a protective layer 610 covering the outer layers of the wires 630, where each wire 630 is composed of a conductor 631 and an insulating layer 632 covering the periphery of the conductor 631, where the conductor 631 of each wire 630 may be connected to the corresponding connection terminal 50 by crimping or welding, and the like, which is not limited herein. Since the automotive high-speed connector 1 is used for transmitting automotive signal data, in order to avoid electromagnetic interference to automotive data signals caused by external environment, a shielding net 620 is further disposed on the outer layer of the plurality of wires 630 of the connecting wire 60, and the protective layer 610 is located on the outer side surface of the shielding net 620. Thus, the shielding net 620 can effectively isolate the signal data in the connecting wire 60, and improve the anti-interference performance of the connecting wire 60. Further, in order to realize the omnibearing shielding protection of signal data in the automobile high-speed connector 1, the shielding mesh 620 of the connecting wire 60 is electrically connected with the shielding main body 20. Therefore, the whole coverage of the shielding layer in the automobile high-speed connector 1 is realized, the interference of the external environment to the signal data in the automobile high-speed connector 1 is effectively avoided, the anti-interference performance of the product is enhanced, and the signal transmission performance of the product is greatly improved.
There are various ways to achieve the electrical connection between the shielding mesh 620 and the shielding main body 20, for example, the shielding mesh 620 and the shielding main body 20 may be connected by welding; or, a metal press buckle is arranged on the shielding net sleeve 620, and when the shielding net sleeve 620 is inserted into the accommodating through hole 210 of the shielding main body member 20, the metal press buckle forms tight fit with the accommodating through hole 210, namely, the connecting wire 60 is fixedly connected with the shielding main body member 20, and the electrical connection between the shielding net sleeve 620 and the shielding main body member 20 is realized; or, the shielding mesh 620 is turned outwards to form a plurality of shielding layers at the end of the connecting wire 60, so that the thickness of the shielding mesh 620 at the end of the connecting wire 60 is increased, when the shielding mesh 620 is inserted into the accommodating through hole 210 and is tightly matched with the accommodating through hole 210, and the shielding mesh 620 and the shielding main body 20 are fixedly connected together, and meanwhile, the electrical connection between the shielding mesh 20 and the shielding main body is also realized.
It can be appreciated that by adopting the above structure, the fixing effect of the terminal block 30 in the accommodating through hole 210 is greatly improved, and when the automobile high-speed connector 1 is matched with the male and female connector in a plugging manner, the contact effect of the wiring terminal 50 is better ensured, the contact impedance is reduced, the reflection loss in high-speed data transmission is reduced, and the requirements of the vehicle-mounted equipment such as an automobile-mounted entertainment system, a 360-degree looking-around system and the like on the high-speed transmission rate of signal data are met. Meanwhile, the automobile high-speed connector 1 is simple in structure, easy to assemble and higher in reliability of electrical connection.
According to the technical scheme of the invention, the limiting piece 40 is arranged on the lead 630 of the connecting wire 60, the limiting piece 40 and the terminal seat 30 are simultaneously inserted and installed in the accommodating through hole 210 of the shielding main body piece 20, and the limiting welt 410 of the limiting piece 40 is clamped between the accommodating through hole 210 and the terminal seat 30, so that the fit clearance between the accommodating through hole 210 and the terminal seat 30 is effectively reduced through the limiting welt 410, the fixing effect of the terminal seat 30 in the accommodating through hole 210 is enhanced, the structure of the automobile high-speed connector 1 is firmer, the tensile property is greatly improved, and the reliability of a product is improved.
Further, in the present embodiment, the limiting member 40 and the terminal block 30 are installed in the accommodating through hole 210 of the shielding main body 20, when the connecting wire 60 is pulled by an external force, the terminal block 30 is driven by the connecting terminal 50, and in order to avoid the offset of the terminal block 30, one end of the limiting member 40 facing the terminal block 30 abuts against the terminal block 30, the limiting member 40 limits the terminal block 30, and prevents the terminal block 30 from moving in the accommodating through hole 210.
In order to facilitate the installation of the terminal block 30 and the shielding main body 20, and avoid the difficult assembly between the terminal block 30 and the shielding main body 20 due to the existence of the limit welt 410, in this embodiment, referring to fig. 5 and 6, the outer circumferential surface of the terminal block 30 is additionally provided with a receiving groove 320 adapted to the limit welt 410, the receiving groove 320 extends from the end of the terminal block 30 near the fixing element along the axial direction of the terminal block 30, and the limit welt 410 is located in the receiving groove 320. In this way, the accommodating groove 320 plays a certain role in avoiding the limit welt 410, and when the terminal seat 30 is mounted to the accommodating through hole 210, the limit welt 410 is accommodated in the accommodating groove 320 of the terminal seat 30, so that the assembling difficulty of the terminal seat 30 is reduced. Further, the bottom of the accommodating groove 320 is provided with a limiting protrusion 330, the limiting protrusion 330 is close to one end of the terminal seat 30 facing the limiting member 40, when the terminal seat 30 is mounted to the accommodating through hole 210, the limiting protrusion 330 in the accommodating groove 320 jacks up the limiting welt 410, so that the limiting welt 410 is clamped more tightly, and the terminal seat 30 is fixed more firmly.
In this embodiment, the limiting member 40 is manufactured by injection molding, and the injection molding process of the limiting member 40 is summarized, the wires 630 of the connecting wire 60 are wrapped by the injection molding material, and then after the limiting member 40 is molded, the wires 630 of the connecting wire 60 directly penetrate through the limiting member 40. Through the above manner, the spacing member 40 and the conductive wire 630 of the connecting wire 60 can form a reliable fixed connection, and when the spacing member 40 is fixed in the accommodating through hole 210, the connecting wire 60 is further fixed, so as to prevent the connecting wire 60 and the terminal seat 30 from being pulled out by external force, thereby damaging the automobile high-speed connector 1. When the stopper 40 is injection-molded, the maximum outer diameter thereof should be identical to the outer diameter of the terminal block 30, so that the terminal block 30 and the stopper 40 are mounted into the receiving through hole 210. It should be emphasized that, after injection molding, the limiting member 40 may be provided with a limiting flange 410 on the outer peripheral surface of the terminal block 30, and then be mounted into the accommodating through hole 210 of the shielding main body 20 together with the terminal block 30; alternatively, an injection mold is provided at the end of the terminal block 30, the injection molding material directly forms the stopper 40 at the end of the terminal block 30, and the stopper welt 410 is formed after the injection molding material on the outer peripheral surface of the terminal block 30 is molded.
Further, in order to make the circumferential stress of the terminal block 30 uniform when the terminal block 30 is fixed in the accommodating through hole 210, in this embodiment, the number of the limiting edges 410 of the limiting member 40 is plural, and the plurality of limiting edges 410 are uniformly distributed along the axial direction of the limiting member 40, and at this time, a plurality of accommodating grooves 320 are also provided on the outer peripheral surface of the terminal block 30 corresponding to the plurality of limiting edges 410, so that the fixed connection between the terminal block 30 and the shielding main body member 20 is more reliable. Wherein the limiting member 40 has two or more limiting welts 410.
In order to facilitate the installation of the terminal block 30 and the stopper 40 in the receiving through hole 210 of the shielding body 20, a guide structure is provided between the terminal block 30, the stopper 40 and the receiving through hole 210. Specifically, referring to fig. 4 to 6, the guide structure is: the inner wall surface of the accommodating through hole 210 is provided with a guide protrusion 220, the outer circumferential surfaces of the terminal seat 30 and the limiting member 40 are provided with a guide groove 340 corresponding to the guide protrusion 220, the guide groove 340 extends along the axial direction of the accommodating through hole 210, and the guide protrusion 220 is positioned in the groove of the lead wire 630 and slides relative to the guide groove 340. In other embodiments, the inner wall surface of the accommodating through hole 210 may also be provided with a guiding rib, and the guiding rib is matched with the guiding groove 340 on the outer peripheral surface of the terminal seat 30 and the limiting member 40.
It can be appreciated that, due to the above guiding structure, when the terminal block 30 and the limiting member 40 are mounted in the accommodating through hole 210, the guiding protrusion 220 is located in the guiding groove 340, so that the relative rotation of the terminal block 30 and the limiting member 40 in the accommodating through hole 210 is also limited, the problem of wiring error caused by deflection of the terminal block 30 is avoided, and a better fool-proof effect is achieved.
In the automobile high-speed connector 1, a plug interface 240 is arranged at one end of the shielding main body member 20 far away from the connecting wire 60, the automobile high-speed connector 1 is connected with other devices through the plug interface 240, wherein the plug interface 240 can be an independent component, and the plug interface 240 is connected with the shielding main body member 20 in a tight fit manner, so that an additional assembly process is required to be added to the automobile high-speed connector 1, and the production efficiency of a product is low; meanwhile, there is a defect that the product cannot be used due to the fact that the socket 240 is not firmly fixed with the shielding main body 20. In order to avoid the above-mentioned drawbacks, in the present embodiment, for the shielding main body 20, the hole wall surface of the end of the accommodating through hole 210 far away from the connecting wire 60 is provided with an elastic flap to form an inserting port 240, that is, the shielding main body 20 and the inserting port 240 are integrally arranged, so that the assembling procedure of installing the inserting port 240 to the shielding main body 20 is reduced, and meanwhile, the problem of unstable fixation between the inserting port 240 and the shielding main body 20 is also solved, thereby effectively improving the reliability of the product.
The connection terminal 50 is preferably connected to the conductive wire 630 of the connection wire 60 by crimping, so as to improve the production efficiency, and avoid the defects of cold joint, solder leakage, etc. during the welding process. When the connection terminal 50 is connected with the wire 630 by a crimping manner, on one hand, there is a risk that the wire 630 falls off from the connection terminal 50 due to the loose crimping; on the other hand, since only the conductor 631 of the wire 630 is generally connected to the connection terminal 50, there is also a risk of tearing the wire 630 when the connection wire 60 is pulled by an external force. In order to reduce the risk, referring to fig. 7, in the present embodiment, the terminal 50 is sequentially provided with a first clamping portion 510 and a second clamping portion 520 along the length direction thereof, the first clamping portion 510 is located at one end of the terminal 50 near the connection wire 60, the insulating layer 632 of the wire 630 of the connection wire 60 is clamped to the first clamping portion 510, and the conductor 631 of the wire 630 of the connection wire 60 is clamped to the second clamping portion 520. In this way, the insulating layer 632 of the wire 630 is also crimped and fixed with the terminal 50 by providing the first clamping portion 510, so as to realize the secondary fixation of the wire 630 of the connecting wire 60, and further greatly improve the connection reliability between the wire 630 of the connecting wire 60 and the terminal 50.
Further, when the terminal 50 is mounted to the terminal block 30, the first clamping portion 510 and the terminal hole 310 form a tight fit, so that, on one hand, the terminal 50 and the terminal block 30 can be relatively fixed, and on the other hand, the injection molding material of the limiting member 40 can be reduced from penetrating into the terminal hole 310 of the terminal block 30. Further, the connection terminal 50 further includes a sealing portion 530 disposed in an annular shape, the sealing portion 530 extends along the length direction of the connection terminal 50 and is located at a side of the second clamping portion 520 away from the first clamping portion 510, and an outer peripheral surface of the sealing portion 530 is attached to an inner wall surface of the terminal hole 310. In this way, a sealing layer is formed between the sealing portion 530 and the terminal hole 310 to further prevent the injection molding material of the stopper 40 from penetrating into the terminal hole 310.
In this embodiment, referring to fig. 1 to 4, when the shielding mesh 620 of the connection wire 60 is inserted into the accommodating through hole 210 of the shielding main body 20, the outer surface of the shielding main body 20 is pressed by an external force, so that the uneven press-connection portion 250 is formed on the inner wall surface of the accommodating through hole 210 of the shielding main body 20, and a tight fit is formed between the press-connection portion 250 and the shielding mesh 620. Thus, on one hand, reliable electrical connection between the shielding main body 20 and the shielding net 620 is realized, the anti-interference performance of the automobile high-speed connector 1 is enhanced, and the automobile high-speed connector 1 has good low-radiation effect; on the other hand, because the surface of the crimping part 250 is uneven, when the crimping part 250 is crimped on the shielding mesh 620, the friction resistance between the crimping part 250 and the shielding mesh 620 is greatly enhanced, so that firm and fixed connection between the shielding mesh 620 and the shielding main body 20 is realized, and the probability of breaking the connecting wire 60 from the connection position with the shielding main body 20 is reduced.
With further reference to fig. 3 and 4, the spacing member 40 is tightly matched with the accommodating through hole 210 of the shielding main body member 20, and the outer peripheral surface of the shielding main body member 20 is recessed inwards so that the inner wall surface of the accommodating through hole 210 forms a blocking part 230, and the end surface of the spacing member 40 facing away from the terminal seat 30 is abutted against the blocking part 230. That is, after the limiting member 40 is mounted in the accommodating through hole 210, the outer side of the shielding main body member 20 is pressed and held, so that the outer peripheral surface of the shielding main body member 20 is recessed inwards, and then the blocking portion 230 is formed in the accommodating through hole 210, and when the connecting wire 60 is pulled by an external force, the limiting member 40 abuts against the blocking portion 230, so that the limiting member 40 can be effectively prevented from being separated from the accommodating through hole 210, and the terminal base 30 is firmly fixed in the accommodating through hole 210. The holding portion 250 and the blocking portion 230 may be provided in two separate structures, or the holding portion 250 and the blocking portion 230 may be provided in the same structure on the shield body 20.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
