Description

Technical Field

[0001] The present application relates to the technical field of automobile connectors, and in particular to an automobile connector that is easy to assemble. Background Art

[0002] Automotive connectors are a type of component that electronic engineers often come into contact with. Their function is very simple: to build a bridge of communication between blocked or isolated circuits in a circuit, so that current can flow and the circuit can achieve its intended function. The forms and structures of automotive connectors are ever-changing, and they are mainly composed of four basic structural components, namely: contact, housing (depending on the type), insulator, and accessories. In the industry, they are usually called sheaths, connectors, and plastic shells.

[0003] The Fakra connector is a high-performance connector designed specifically for the automotive industry, especially for wireless communications and other high-frequency signal transmission applications in vehicle systems.

[0004] Fakra connectors are known for their reliability and flexibility, improving the functionality and reliability of in-vehicle systems.

[0005] They are mainly used to transmit high-frequency signals and data, such as car Bluetooth, GPS navigation, wireless networks, etc.

[0006] In the field of autonomous driving, Fakra terminals are widely used in the connection of key components such as vehicle cameras, radars, and vehicle communication systems.

[0007] The Mini Fakra board-end connector is the next generation of miniaturized Fakra connectors. Compared with traditional Fakra products, this interface supports data transmission up to 20Gbps and can reduce installation space by 80%.

[0008] According to the requirements of USCAR-49, the Mini Fakra board-end connector needs to achieve an axial tension of 110N and a lateral tension of 75N, and the tension is mainly provided by the buckle of the plastic shell. In addition to the buckle strength of the plastic shell, how to fix the plastic shell is also very important.

[0009] In the prior art Mini Fakra connector, due to its small size, it can only realize a one-way assembly relationship, so its adaptability to multi-directional requirements is poor. Summary of the invention

[0010] Based on this, the purpose of the present application is to provide an automotive connector that is easy to assemble and has the advantage of being able to switch in four directions at will.

[0023] The limiting strip is used to be assembled and fastened with the limiting groove to enhance the assembly fastness of the plastic shell and the shielding shell.

[0024] Furthermore, a dividing groove is formed between the two sides of the oblique buckle and the limiting groove, and the dividing groove is used to separate the two sides of the oblique buckle from the plastic shell, so that the oblique buckle can swing relative to the plastic shell;

[0025] The oblique buckle is arc-shaped, and an oblique accommodation space is formed between the oblique buckle and the inner wall of the plastic shell.

[0026] Furthermore, it also includes a fastener, which is arc-shaped, and the cross-sectional shape of the fastener is the same as the cross-sectional shape of the oblique accommodation space;

[0030] A thin wall is formed on the inner wall of the fastener and on one side of the large accommodating cavity, so that when the large accommodating cavity expands, the thin wall is deformed outwards.

[0031] Furthermore, the wall thickness outside the small accommodating cavity is greater than the wall thickness of the thin wall.

[0032] Furthermore, matching strips are formed on both sides of the fastener, and the matching strips are used for assembly and connection with the dividing grooves.

[0033] Furthermore, a flexible strip is formed on the expanded end surface of the fastener, and the flexible strip is used to separate the fastener from the oblique buckle when pulled.

[0034] Further, two side walls of the fastener are respectively formed with a plurality of strip grooves;

[0035] Two of the strip grooves are located on one side wall of the fastener, and the other two of the strip grooves are located on the other side wall of the fastener;

[0062] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating positions or positional relationships, are based on the positions or positional relationships shown in the drawings, and are 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 cannot be understood as a limitation on the present application. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0063] The exemplary automotive connector for easy assembly of this application has two main purposes:

[0064] First, it can be freely combined. It can realize the assembly relationship of relative position transformation in four directions.

[0065] Second, ensure stable communication. It can ensure that the plastic shell and the shielding shell are assembled tightly at different temperatures and have a good anti-loosening effect; furthermore, it ensures stable communication in the automotive connector and strong anti-interference ability.

[0066] See also Figure 1-Figure 20 , an exemplary automobile connector that is easy to assemble in the present application includes a plastic shell 20, a shielding shell 10, a first rubber core (not shown), and a second rubber core (not shown);

[0067] The first rubber core and the second rubber core are respectively inserted into the shielding shell 10 and are respectively tightly assembled with the shielding shell 10;

[0068] The plastic shell 20 is snap-connected to the shielding shell 10 and is relatively detachable;

[0069] The plastic shell 20 includes an outer shell 21 and an oblique buckle 22; four receiving through holes 23 are formed at the end of the outer shell 21, and the oblique buckle 22 is disposed at the end of the outer shell 21 and located in the receiving through holes 23; the four oblique buckles 22 are symmetrically arranged in pairs;

[0070] The shielding shell 10 includes an assembly shell 11, a sleeve 12, a limit strip 13, and a convex ridge 14; the end of the sleeve 12 is fixed to the assembly shell 11, and the four sleeves 12 are symmetrically arranged in pairs, the sleeve 12 is movably sleeved with the accommodating through hole 23, and the four accommodating through holes 23 are correspondingly assembled and connected with the four sleeves 12;

[0071] The end of the sleeve 12 is formed with a receiving groove 15, and the receiving groove 15 is used for assembly and connection with the oblique buckle 22;

[0072] The sleeve 12 is provided with the limiting strips 13 on both sides of the receiving groove 15, and the receiving through hole 23 is also formed with a limiting groove (not marked in the figure), which is detachably connected to the limiting strips 13;

[0073] The convex ridge 14 is disposed on the side of the receiving groove 15 on the sleeve 12 to resist the end of the oblique buckle 22;

[0074] The two first rubber cores are respectively assembled and connected with two of the sleeves 12 , and the two second rubber cores are respectively assembled and connected with the other two of the sleeves 12 .

[0075] In the present application, since the oblique buckles are symmetrical in pairs, and the sleeves are also symmetrical in pairs, and the relative position relationship between the oblique buckles and the sleeves is set accordingly, the four oblique buckles can be assembled with the four sleeves; the four accommodating grooves are symmetrically distributed in pairs, and the accommodating grooves are arranged correspondingly to the oblique buckles, so that when the oblique buckles and the accommodating grooves are assembled, any oblique buckle can be assembled and connected with any accommodating groove; limiting grooves are formed on both sides of the accommodating through hole, and limiting strips are formed on both sides of the accommodating groove of the sleeve, and the limiting strips are set correspondingly to the limiting grooves, and the cross-sectional shapes are consistent, so that the assembly of the limiting strips and the limiting grooves is tight, and the assembly of the limiting strips and the limiting grooves can be freely changed. Therefore, the assembly position relationship between the plastic shell and the shielding shell can be changed in four directions, and the tightness of the assembly is guaranteed.

[0076] Specifically, the assembly relationship between the plastic shell and the shielding shell in four directions, such as Fig. 20 According to the above technical features, a technical problem of the present application is solved, and the effect of being able to change in four directions is achieved.

[0077] In some preferred embodiments, as shown in the drawings, the outer shell and the assembly shell are respectively formed with edges, the accommodating groove is away from the symmetry axis of the four sleeves and close to the edge of the assembly shell 11; the oblique buckle is close to the edge of the outer shell.

[0078] In some preferred embodiments, the oblique buckle 22 is placed obliquely relative to the sleeve 12. When the sleeve 12 is assembled and fastened with the plastic shell 20, the end of the oblique buckle 22 is away from the sleeve 12, and the top of the oblique buckle 22 is close to the sleeve 12, so that the plastic shell 20 is assembled and fastened with the shielding shell 10 through the oblique buckle 22.

[0079] The oblique buckle 22 is used to prevent the plastic shell 20 from loosening when assembling the shielding shell 10;

[0080] The limiting strip 13 is used to be assembled and fastened with the limiting groove to enhance the assembly fastness of the plastic shell 20 and the shielding shell 10 .

[0081] In this preferred embodiment, further features of the oblique buckle are specifically described so that the oblique buckle can better achieve the purpose of the present application.

[0082] In some preferred embodiments, a dividing groove 24 is formed between the two sides of the oblique buckle 22 and the limiting groove, and the dividing groove 24 is used to separate the two sides of the oblique buckle 22 from the plastic shell 20, so that the oblique buckle 22 can swing relative to the plastic shell 20;

[0083] The oblique buckle 22 is arc-shaped, and an oblique accommodation space A1 is formed between the oblique buckle 22 and the inner wall of the plastic shell 20 .

[0084] In this preferred embodiment, the features of the oblique buckle are further described, such as providing a dividing groove 24 so that the oblique buckle can more easily achieve elastic deformation and can be more easily used in conjunction with the accommodating groove 15.

[0085] In some preferred embodiments, a fastener 31 is further included, the fastener 31 is arc-shaped, and the cross-sectional shape of the fastener 31 is the same as the cross-sectional shape of the oblique accommodation space A1;

[0086] A large accommodating cavity B1 and a small accommodating cavity B2 are respectively formed in the fastener 31 along the length direction, wherein the small accommodating cavity B2 is located at the narrow end of the fastener 31, and the large accommodating cavity B1 is located at the expanded end of the fastener 31;

[0087] A radial tube is radially arranged in the middle of the fastener 31, and a radial cavity B3 is formed in the radial tube;

[0088] The radial cavity B3 is filled with water, the small accommodating cavity B2 is filled with water, and the large accommodating cavity B1 is filled with inert gas;

[0089] A thin wall M is formed on the inner wall of the fastener 31 and on one side of the large accommodating cavity B1 , so that when the large accommodating cavity B1 expands, the thin wall M is deformed outward.

[0090] In the prior art, there is still a problem that as the temperature changes, the connection of the automobile connector is not stable enough, which in turn affects the stability of communication and even affects the anti-interference ability of the automobile connector. Based on this, the fastener provided by the present application and the effect of strengthening the connection and fastening thereof are used to solve this problem.

[0091] In this preferred embodiment, a technical solution for another purpose of the present application is provided, which is achieved by providing a fastener 31. By providing the fastener 31, the assembly and fastening of the oblique buckle and the receiving groove can be ensured regardless of high or low temperatures.

[0092] At high temperatures, the gas in the large accommodating chamber B1 expands, causing the thin wall M to swell. Due to the abutment between the thin wall and the oblique buckle, the oblique buckle is squeezed and deformed. The direction of the extrusion deformation is toward the axial direction of the sleeve, making the oblique buckle closer to the sleeve, and the abutment of the convex ridge against the oblique buckle is closer to the inside, which makes the oblique buckle and the accommodating groove fit more tightly, and the oblique buckle and the accommodating groove are not easy to loosen.

[0093] At low temperatures (greater than 0°C), since water is injected into the small accommodating cavity B2 and the radial cavity B3 respectively, the water is not easy to shrink at this temperature, and the volume change is small and relatively negligible, so that the lateral direction of the fastener is affected by the small accommodating cavity B2, while the lateral bottom shape is kept stable; the radial direction of the fastener is affected by the radial cavity B3, while the radial top shape is kept stable; due to the large accommodating cavity B1 arranged along the lateral direction in the middle of the fastener, the gas is easy to shrink in a low temperature environment, so that the two sides of the upper part of the fastener are contracted. Since the small accommodating cavity is located below the large accommodating cavity, the bottom of the fastener is not easy to deform in the lateral direction, which ensures that the bottom of the fastener is not easy to change in size regardless of high or low temperatures, so that the bottom of the fastener is tightly assembled with the bottom of the oblique accommodating space A1; similarly, due to the radial cavity arranged in the radial direction, the radial direction of the middle part of the fastener is also not easy to deform, and thus has a good radial support effect regardless of high or low temperatures. Therefore, in a low temperature environment, the oblique buckle is assembled and tightened with the accommodating groove through the part on the fastener corresponding to the radial cavity. In fact, due to the shrinkage of the large accommodating cavity at low temperature, the radial cavity has an oblique support, thereby enhancing the structural stability of the radial cavity.

[0094] At lower temperatures (0°C and below), the volume of water expands due to freezing, thereby better pressing the oblique buckle against the wall of the receiving groove, making the oblique buckle and the receiving groove more tightly assembled and less likely to loosen.

[0095] At room temperature, the oblique buckle is normally pressed against the inner wall of the receiving groove, and its end is normally pressed against the surface of the convex edge, so as to prevent the buckle from loosening under normal conditions. At room temperature, due to the strengthening effect of the fastener, the oblique buckle is not easy to loosen from the receiving groove.

[0096] Therefore, according to the description of the above four temperature states, regardless of the temperature state, the fastener of the present application can achieve the effect of strengthening the assembly tightness of the oblique buckle and the accommodating groove, thereby achieving a good anti-loosening effect.

[0097] In some preferred embodiments, the wall thickness of the thin wall is greater than 1 mm. In some preferred embodiments, the wall thickness of the thin wall is 2 mm. The thin wall is the thinnest part of the wall thickness of the large accommodating cavity, and is used for thermal expansion, and deformation occurs, and the deformation is caused by gas expansion, not just thermal expansion itself.

[0098] In some preferred embodiments, the wall thickness outside the small accommodation cavity B2 is greater than the wall thickness of the thin wall M. The description of this feature is to better ensure that the thin wall is deformed preferentially.

[0099] In some preferred embodiments, matching strips 33 are formed on both sides of the fastener 31 , and the matching strips 33 are used for assembly and connection with the dividing groove 24 .

[0100] The matching strips 33 are used to strengthen the assembly and connection fastening of the fastener and the dividing groove, and also ensure the stability of the assembly of the fastener and the oblique accommodation space. Because the two matching strips 33 are respectively assembled and fastened with the two dividing grooves 24, the fastener can be connected and fastened relative to the oblique accommodation space, and thus the matching strips 33 also play a role in strengthening the assembly and fastening of the fastener and the oblique accommodation space.

[0101] In some preferred embodiments, a flexible strip 32 is formed on the expanded end surface of the fastener 31 , and the flexible strip 32 is used to separate the fastener 31 from the oblique buckle 22 when pulled.

[0102] The flexible strip 32 is provided to facilitate pulling of the fastener so that the fastener can be separated from the oblique accommodation space in a manual state.

[0103] In some preferred embodiments, two side walls of the fastener 31 are respectively formed with a plurality of strip grooves 34;

[0104] Two of the strip grooves 34 are located on one side wall of the fastener 31 , and another two of the strip grooves 34 are located on the other side wall of the fastener 31 ;

[0105] In the vertical placement perspective of the fastener 31 , one of the strip grooves 34 is located between the large accommodating cavity B1 and the small accommodating cavity B2 , and the other strip groove is located above the large accommodating cavity B1 .

[0106] In the preferred embodiment, the positional relationship between the large accommodating cavity and the small accommodating cavity is described, so as to better achieve another purpose of the present application, that is, to strengthen the anti-loosening of the oblique buckle and the accommodating groove.

[0107] In some preferred embodiments, the fastener 31 is made of plastic, and the fastener 31 is made of the same material as the plastic housing.

[0108] In some preferred embodiments, the arc length of the fastener 31 is 90°, and the arc length between the two dividing grooves 24 on the same receiving through hole 23 is 90°;

[0109] The wall surface of the limiting groove is formed with a strip-shaped rib 25, and the rib 25 is used to strengthen the assembly tightness between the limiting strip 13 and the limiting groove;

[0110] The plastic shell 20 and the shielding shell can form four relative placement positions for assembly.

[0111] The fasteners in the present application are made of the same material as the whole (the same material is used as the whole), and the molding method can be a split casting, and then the two parts are glued and fastened; or a split casting first, and then hot melt bonding. In some preferred schemes, the fasteners are made of plastic material, so that they have a certain deformation ability when the temperature changes; the deformation ability requirement is not high, so the flexibility requirement of the material is not high.

[0112] Compared with the prior art, this application has at least the following technical effects:

[0113] 1) The assembly relationship can be transformed in four directions to achieve a variety of assembly methods.

[0114] 2) The oblique buckle 22 and the receiving groove 15 can be assembled more tightly in the case of thermal expansion and contraction.

[0115] 3) The large accommodating cavity B1 is filled with inert gas, which is greatly affected by thermal expansion and contraction and is prone to deformation. When the temperature rises, the thin wall M of the large accommodating cavity B1 forms a bulge, which makes the oblique buckle 22 more tightly pressed against the accommodating groove 15, playing a role in preventing loosening and also playing a role in assembly and tightening. When the temperature drops, since there is water in the small accommodating cavity B2 and the radial cavity B3, it is not easy to deform, so that the radial direction of the middle part of the fastener 31 presses the oblique buckle 22 against the accommodating groove 15, which plays a good role in preventing loosening and a good role in assembly and tightening.

[0116] 4) Regardless of high or low temperature environments, the connector of the present application can ensure good assembly and tightening effects; thereby making the automotive connector of the present application have good environmental adaptability and adaptability to different temperatures.

[0117] 5) By pulling the flexible strip 32 by hand, the fastener 31 can be separated from the oblique buckle 22, so that the fastener 31 can be loosened manually. Regardless of the temperature environment, the anti-loosening effect ensures stable communication in the connector and improves the anti-interference ability.

[0118] Compared with the prior art, the present application cleverly uses the principle of thermal expansion and contraction, and can ensure the tight assembly of the connector regardless of high or low temperatures, thereby ensuring stable communication and achieving strong anti-interference capabilities.

[0119] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
