Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automobile accessories, in particular to a data connection structure and a connector. BACKGROUND

[0002] The automobile data connector is used for transmitting data on the automobile and is suitable for the dynamic environment of high-speed automobiles. However, with the rise of 5G mobile networks and the increasing amount of data to be transmitted, the requirements for the data connector are also increasing. The shielding tube of the vehicle-mounted communication connector used in automobile assembly is a two-section structure. In order to ensure the structural strength of the two-end plug-in structure, the existing shielding tube is limited. Moreover, the two-section structure of the shielding tube is relatively complex to manufacture, and it is difficult to ensure the precision after assembly, resulting in poor concentricity with the cable, terminal and the like. The front end of the outer conductor is designed to be open, which is easy to cause the terminal to be assembled into the shell and scratch out debris, thereby causing safety hazards and instability after assembly. CONTENT OF THE UTILITY MODEL

[0003] The application aims to provide a data connection structure and a connector to solve the defects of complex structure, high cost and poor concentricity in the prior art.

[0004] To achieve the above-mentioned purpose, the application adopts the following technical scheme:

[0005] In a first aspect, the application discloses a data connection structure, which comprises an outer conductor, an insulator and an inner conductor in a concentric sleeve connection.

[0006] The outer conductor comprises a front spring piece, a middle hollow column and a cable inlet part which are integrally formed, and the front spring piece, the middle hollow column and the cable inlet part are connected in an axial sequence. The inner conductor is clamped in the cavity of the insulator, the insulator is fixed in the outer conductor, and the outer wall of the front spring piece is circumferentially fixed with a guide piece.

[0007] In a further aspect of the application, a plurality of simply supported beams are radially and equiangularly arranged at one end of the front spring piece away from the middle hollow column, and the guide piece is arranged on the front spring piece between two adjacent simply supported beams.

[0008] In a further aspect of the application, one side of the insulator is attached to the inner wall of the front spring piece, and the other side of the insulator is attached to the inner wall of the middle hollow column. The structure of the insulator matches the structures of the front spring piece and the middle hollow column.

[0009] In a further aspect of the application, an excessive diameter gradient body is arranged at the connection between the front spring piece and the middle hollow column.

[0010] In a further aspect of the application, an opening is arranged on the outer wall of the cable inlet part.

[0011] In a further embodiment of this application, a cable clamp is axially connected to one end of the cable inlet away from the intermediate hollow post, and the cable clamp is provided with complementary locking bodies at both ends along the radial direction of the outer conductor.

[0012] In a further embodiment of this application, the inner conductor includes a front plug-in portion, a middle connecting rod portion, and a rear connecting portion connected in sequence. The front plug-in portion is placed in the cavity on the side of the insulator near the front spring piece. The rear connecting portion is used to crimp the wire core. An elastic limiting member is provided on the outer wall of the middle connecting rod portion, and the limiting member abuts against the inner wall of the insulator.

[0013] In a further embodiment, the end of the front insertion part is provided with a shrinkage groove in the axial direction.

[0014] Secondly, this application provides a connector that includes the aforementioned data connection structure and controller, with the data connection structure and controller connected by a cable.

[0015] The beneficial effects of this application are as follows:

[0016] The front spring, the middle hollow column, and the cable entry part of this application are designed as an integrated unit. The multi-segment structure is optimized into a single unit, which reduces the number of parts and the cost of the parts. In actual production, the insulator is directly fixed inside the outer conductor while the outer conductor is being manufactured, which reduces the assembly steps and assembly costs. The front spring is equipped with a guide to prevent the outer conductor from scraping out debris when it is assembled into the equipment housing port, thus eliminating safety hazards.

[0017] The elastically set limiting component on the middle connecting rod of the inner conductor provides a good limiting effect after the inner conductor is installed in the insulator, ensuring the stability of the inner conductor installation. The elastic setting of the limiting component increases the adaptability of the inner conductor installation to a certain extent, and it can be fixed within a certain range of installation space.

[0027] In further embodiments, one side of the insulator 6 is attached to the inner wall of the front sheet 1, the other side of the insulator 6 is attached to the inner wall of the hollow column 2, the structure of the insulator 6 matches the structure of the front sheet 1 and the hollow column 2; in addition, a diameter gradually changing body is arranged at the connection between the front sheet 1 and the hollow column 2, which plays the role of connecting the front sheet 1 and the hollow column 2, and limits the insulator 6, and in actual production, the outer conductor 5 is integrally stamped by a mold, high-elasticity tin bronze is used as the material, the insulator 6 is fixed when the production is completed, and the operation is simple and the production steps are reduced.

[0028] As shown in the accompanying drawings Figure 1 and Figure 2 In this embodiment, the outer wall of the cable inlet part 3 is provided with a corrugated opening 3a, which is not only conducive to the assembly of the cable, but also ingeniously utilizes the part space, avoids irregular protrusions after the cable clamp plate 4 is crimped, and affects the free rotation of the terminal in the shell. The front end of the cable inlet part 3 is connected to the middle hollow column 2, which is crucial for impedance matching of electrical transmission, greatly reducing the reflection loss of information during transmission, and also fully utilizing the existing structure space, avoiding the need to increase the outer conductor 5 due to impedance matching, resulting in a bloated structure. The front end of the middle hollow column 2 is connected to the front elastic sheet 1,

[0029] In a further embodiment, the cable clamp plate 4 is provided with a structure complementary locking body at both ends of the outer conductor 5 in the radial direction. Generally, the locking body includes a first locking edge and a second locking edge, the first locking edge is provided with a notch, and the corresponding second locking edge is provided with a protrusion.

Simulation shows that the impedance and return loss insertion loss are excellent; the structure is compact, small in size, small in space occupation, and conducive to automobile wiring system wiring.
