Description

Technical Field

[0001] This application relates to the technical field of connection devices, and particularly to automotive connectors. Background Art

[0002] Automotive connectors are devices used in automotive electrical systems to connect electronic components such as wires, cables, and circuit boards. They provide reliable electrical contact between various electrical devices inside and outside the vehicle, ensuring the effective transmission of power and signals. The design of automotive connectors needs to consider various factors, including durability, waterproof and dustproof capabilities, vibration resistance, and ease of installation and maintenance.

[0003] Automotive connectors can be divided into different types, which vary according to their uses, positions, and the electrical systems they connect. Common types of automotive connectors include: wire-to-wire connectors, wire-to-board connectors, board-to-board connectors, power connectors, signal connectors, and high-voltage connectors.

[0004] The FAKRA connector is a radio frequency (RF) coaxial connector designed specifically for automotive radio applications. Its name comes from the German "Fachkreis Automobil", which means "Automotive Industry Expert Group". This connector is usually used to transmit high-frequency signals, such as in-car radios, GPS navigation systems, mobile phone antennas, and wireless communication devices.

[0005] Among them, the MINI FAKRA board-end connector belongs to the next-generation miniaturized product of the FAKRA connector. Compared with traditional FAKRA products, this interface supports data transmission of up to 20 Gbps and can reduce the installation space by 80%. According to the requirements of USCAR-49, the MINI FAKRA board-end connector needs to achieve a large axial tensile force and a large lateral tensile force, and the tensile force is mainly provided by the buckle of the plastic housing. In addition to the buckle strength of the plastic housing, how to fix the plastic housing is also very important.

[0006] Based on this, when the prior art ensures the tensile stress and lateral stress of the plastic housing, it becomes very difficult to achieve the assembly versatility and variable angle, which is also a problem existing in the existing MINI FAKRA connectors. Summary of the Utility Model

[0007] Based on this, the purpose of this application is to provide an automotive connector, which has the advantages of improving the assembly versatility and variable square characteristics while ensuring the axial tensile force and lateral tensile force.

[0008] In one aspect of the present application, an automotive connector is provided, comprising an outer shell, an inner sleeve, and an assembly shell; a plurality of inner sleeves are mounted on an end of the assembly shell, a plurality of alignment through holes are formed in the outer shell, and the inner sleeves are nested and assembled with the alignment through holes;

[0009] The plurality of inner sleeves are symmetrically distributed at the end of the assembly shell, and the arrangement positions of the alignment through holes correspond to the positions of the plurality of inner sleeves;

[0010] A buckle is formed in the outer shell at the alignment through hole, and a buckle groove is formed at the end of the inner sleeve connected to the assembly shell; the buckle groove is used to buckle and fasten with the buckle;

[0011] The plurality of alignment through holes are evenly distributed along the axis at equal angles, and the plurality of buckles are evenly distributed along the axis at equal angles.

[0012] In the automotive connector described in the present application, the assembly direction of the inner sleeve and the assembly housing can be changed, because each inner sleeve and the alignment through hole can be assembled. They have exactly the same structure, but the angles and positions are different. Therefore, by rotating the relative positions, the variable direction installation and assembly of the inner sleeve and the assembly housing can be achieved.

[0013] Furthermore, separation grooves are formed in the outer shell on both sides of the buckle;

[0014] The buckle is inclined relative to the end surface of the outer shell, and the inclination direction is that one end connected to the end surface of the outer shell is away from the axis, and the other end is close to the axis.

[0015] Furthermore, the inner sleeve is provided with limited fastening strips on both sides of the buckling groove, and the outer shell is provided with two limited fastening grooves at the alignment through hole, wherein the limited fastening strips and the limited fastening grooves have the same cross-sectional shape and are tightly matched;

[0016] The plurality of position-limiting fastening strips on the same side are evenly distributed at equal angles along the axis, and the plurality of position-limiting fastening grooves on the same side are evenly distributed at equal angles.

[0017] Furthermore, the cross-sectional area of one of the two position-limiting and fastening strips on the same inner sleeve is larger than that of the other; the cross-sectional area of one of the corresponding two position-limiting and fastening grooves is larger than that of the other.

[0018] Furthermore, a stop strip is formed at the end of the inner sleeve located at the buckling groove, and the stop strip is used to strengthen the end that abuts against the buckle.

[0019] Furthermore, the side wall of the limiting fastening groove is formed with an interference strip, and the interference strip is arranged along the length direction of the outer shell.

[0020] Further, the cross-sectional shape of the limit fastening groove is triangular.

[0021] Further, the outer housing is a plastic housing.

[0022] Further, the assembly housing and the inner sleeve are integrally formed.

[0023] Further, it includes four said inner sleeves, and four said alignment through holes are correspondingly provided.

[0024] For better understanding and implementation, the present application will be described in detail below with reference to the accompanying drawings. Description of the Drawings

[0035] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0036] Please refer to Figures 1-9 As shown, an exemplary automotive connector of the present application includes an outer housing 30, an inner sleeve 20, and an assembly housing 10; a plurality of the inner sleeves 20 are installed at the end of the assembly housing 10, a plurality of alignment through holes B are formed in the outer housing 30, and the inner sleeve 20 is nested and assembled with the alignment through hole B;

[0037] A plurality of the inner sleeves 20 are symmetrically distributed at the end of the assembly housing 10, and the arrangement positions of the alignment through holes B correspond to the positions of the plurality of inner sleeves 20;

[0038] A buckle 31 is formed at the position of the alignment through hole B in the outer housing 30, and a fastening groove A is formed at the end of the inner sleeve 20 connected to the assembly housing 10; the fastening groove A is used for fastening with the buckle 31;

[0039] A plurality of the alignment through holes B are evenly distributed at equal angles along the axis, and a plurality of the buckles 31 are evenly distributed at equal angles along the axis.

[0040] In the present application, the equal angle means that in the cross-sectional view, the angle between any two adjacent features is equal, and thus, their axis connections form a regular polygon.

[0041] In this application, the axis line refers to the symmetric center line of multiple inner sleeves 20 or the symmetric center line of multiple alignment through holes B. For example, when three inner sleeves 20 and three alignment through holes B are provided, from the perspective of the cross-section, the connection line of the centers of the three inner sleeves 20 forms an equilateral triangle, and the connection line of the centers of the three alignment through holes B also forms an equilateral triangle of the same kind. The geometric center of these two equilateral triangles is the axis referred to in this application, and the straight line along the length direction of the inner sleeve 20 passing through this point is the axis line. Since the inner sleeve 20 and the outer housing 30 are in a sleeved relationship, in the assembled state, the axis line is also applicable to the outer housing 30. Another example is that when four inner sleeves 20 and four alignment through holes B are provided, a square is formed; when five inner sleeves 20 and five alignment through holes B are provided, a regular pentagon is formed. Correspondingly, the axis lines are the geometric centers of the square and the regular pentagon respectively.

[0042] In this application, the purpose of describing the axis line is to facilitate the expression of the relative positional relationship among multiple inner sleeves 20, multiple alignment through holes B, and multiple buckles 31. In this application, in order to facilitate the assembly connection between an alignment through hole B of the outer housing 30 and any one of the inner sleeves 20, by introducing the virtual concept of the axis line, the purpose of this application can be more easily understood: multi-angle transformation for free assembly.

[0043] As Figure 9 and Figure 10 shown, in the four quadrants of the center line, the four inner sleeves are equally angularly distributed, the four alignment through holes are equally angularly distributed, the accessory structures on the four inner sleeves are also equally angularly distributed, and the accessory structures on the four alignment through holes are also equally angularly distributed. Thus, free replacement and free assembly can be carried out in four directions. After the assembly transformation direction, as Figure 6 shown.

[0044] The variable angle or variable direction in this application means that when the outer housing 30 is assembled with the inner sleeve 20, any one of the alignment through holes B can be assembled and connected with any one of the inner sleeves 20. Thus, even if the relative direction is changed, the assembly connection between the outer housing 30 and the inner sleeve 20 can still be carried out.

[0045] In some preferred embodiments, partition grooves C are respectively formed on both sides of the buckle 31 inside the outer housing 30;

[0046] The buckle 31 is inclined relative to the end face of the outer housing 30, and the inclination direction is that one end connecting the end face of the outer housing 30 is far from the axis line, and the other end is close to the axis line.

[0047] By providing the separation groove C, both sides of the buckle 31 are independent of the outer housing 30, and one end of the buckle 31 is connected to the outer housing 30, so that the buckle 31 can bend and deform relative to the outer housing 30 to facilitate the connection and assembly of the inner sleeve 20 and the buckle 31.

[0048] In some preferred embodiments, limiting and fastening strips 21 are respectively formed on both sides of the inner sleeve 20 at the engaging groove A, and two limiting and fastening grooves D are further formed on the outer housing 30 at the alignment through hole B. The limiting and fastening strips 21 and the limiting and fastening grooves D have the same cross-sectional shape and are tightly fitted.

[0049] The multiple limiting and fastening strips 21 on the same side are evenly distributed at equal angles along the axis, and the multiple limiting and fastening grooves D on the same side are evenly distributed at equal angles.

[0050] When the inner sleeve 20 and the outer housing 30 are assembled, the assembly of the inner sleeve 20 and the outer housing 30 becomes tighter through the assembly and connection of the limiting and fastening strips 21 and the limiting and fastening grooves D.

[0051] In this application, limiting and fastening strips 21 are respectively provided on both sides of the same inner sleeve 20, and limiting and fastening grooves D are respectively formed on both sides of the same alignment through hole B. In the example shown in the drawings, not all eight limiting and fastening strips 21 are in a symmetric relationship, nor are all eight limiting and fastening strips 21 in a position relationship of being evenly distributed at equal angles along the axis. Only four of them are evenly distributed at equal angles along the axis, and the other four are evenly distributed at equal angles along the axis.

[0052] In some preferred embodiments, for the two limiting and fastening strips 21 on the same inner sleeve 20, the cross-sectional area of one is larger than that of the other; for the corresponding two limiting and fastening grooves D, the cross-sectional area of one is larger than that of the other.

[0053] In this embodiment, for the two limiting and fastening strips 21 on the same inner sleeve 20, one is larger and the other is smaller. Such a setting can play an anti-misassembly role. Since one of the limiting and fastening strips 21 is large and the other is small, then one of the limiting and fastening grooves D is large and the other is small.

[0054] In some preferred embodiments, a resisting strip is further formed at the end of the inner sleeve 20 at the engaging groove A, and the resisting strip is used to strengthen the abutment against the end of the buckle 31.

[0055] The provision of the resisting strip can increase the cross-sectional area at the end face of the engaging groove A, so that the abutment between the buckle 31 and the inner sleeve 20 is tighter and not easily loosened.

[0056] In some preferred embodiments, an interference strip 32 is formed on the side wall of the limiting and fastening groove D, and the interference strip 32 is arranged along the length direction of the outer housing 30.

[0057] The setting of the interference stripes 32 increases the connection tightness during the assembly of the outer housing 30 and the inner sleeve 20, making the assembly of the outer housing 30 and the inner sleeve 20 more secure.

[0058] In some preferred embodiments, the cross-sectional shape of the limit fastening groove D is triangular.

[0059] In some preferred embodiments, the outer housing 30 is a plastic housing. The material of the plastic is softer than that of the inner sleeve 20.

[0060] In some preferred embodiments, the assembly housing 10 and the inner sleeve 20 are integrally formed.

[0061] In some preferred embodiments, there are four of the inner sleeves 20, and four of the alignment through holes B are correspondingly provided.

[0062] For the automotive connector described in the present application, the assembly of the inner sleeve 20 and the assembly housing 10 can be rotated in different directions because each inner sleeve 20 can be assembled with the alignment through hole B. They have exactly the same structure, except for the different angles and positions of placement. Therefore, by rotating the relative positions, the variable-direction installation and assembly of the inner sleeve 20 and the assembly housing 10 can be achieved.

[0063] For the automotive connector of the present application, the inner sleeve 20 and the outer housing 30 can be freely rotated relative to each other to change the angle for assembly, achieving a connection relationship that is convenient for assembly and allows for free assembly at multiple angles.

[0064] The above embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application.
