[0030] By providing an in-vehicle wire-end floating connector and a connector assembly in an embodiment of the present application, the technical problem of a small correctable position offset in the prior art is solved.

[0031] The technical solution in the embodiment of the present application for solving the above technical problem is generally as follows:

[0032] By providing a camera rear housing, a sealing cover, a center conductor, an insulator, a floating conductor, an outer conductor, and a cable assembly, the center conductor is arranged inside the insulator and electrically connected to the core wire of the cable assembly. The floating conductor is sleeved outside the insulator, and the outer conductor is sleeved on the upper half of the floating conductor. Moreover, the top end of the outer conductor is fixed inside the cable fixing part of the sealing cover.

Compared with the prior art, it effectively corrects a large-amplitude position offset and realizes a large mating tolerance. At the same time, the in-vehicle wire-end floating connector has fewer components and is easy to install, effectively improving the production efficiency.

[0033] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementations disclosed below.

[0034] It should be noted that in this application, if there are any directional indications, such as front, rear, left, right, up, down, front end, rear end, left end, right end, upper part, lower part, left side, right side, longitudinal direction, transverse direction, axial direction, radial direction, front side, back side, etc., they are all relative concepts.

[0035] As Figures 1 to 11 shown, this is an embodiment of the present application:

[0036] A connector assembly 1000 includes a board - end connector 900 and a vehicle - mounted wire - end floating connector 100. The board - end connector 900 includes: a housing 91 having a cavity 911, an insulating rubber core 92 disposed in the cavity 911, and a center pin 93 disposed in the insulating rubber core 92. The vehicle - mounted wire - end floating connector 100 includes a camera rear housing 2 made of metal, a sealing cover 3, a center conductor 4, an insulator 5, a floating conductor 6, an outer conductor 7, and a cable assembly 8. When the board - end connector 900 and the vehicle - mounted wire - end floating connector 100 are plugged together, the floating conductor 6 is inserted into the cavity 911 and electrically connected to the housing 91, and the center pin 93 is electrically connected to the center conductor 4.

[0037] Specifically, the cable assembly 8 includes a cable main body 81, a core wire 82, a shielding layer 83, and a cable sleeve 84 sleeved outside the shielding layer 83; the camera rear housing 2 has a main body portion 21, a docking portion 22, a mounting portion 23, and a vertically - penetrating docking cavity 24 and mounting cavity 25. A limiting portion 26 extending from the cavity wall into the cavity 24 is provided in the docking cavity 24. The mounting portion 23 enables the camera rear housing 2 to be plugged with a camera front housing (not shown). The board - end connector 900 is arranged in the mounting cavity 25; the sealing cover 3 has a cable fixing portion 31 and a rear - housing fixing portion 32. The cable fixing portion 31 is used for the fixed connection between the cable main body 81 and the sealing cover 3, and the rear - housing fixing portion 32 is used for fixedly connecting the docking portion 22 to the sealing cover 3. The center conductor 4 is disposed inside the insulator 5 and electrically connected to the core wire 82. One end of the floating conductor 6 is sleeved outside the insulator 5, and the other end is riveted outside the cable sleeve 84. The outer conductor 7 is sleeved on the upper half of the floating conductor 6, and the top end of the outer conductor 7 is fixed inside the cable fixing portion 31. In the longitudinal direction of the docking cavity 24, the limiting portion 26 limits the bottom end of the outer conductor 7 in the docking cavity 24 of the camera rear housing 2, and there is a gap X between the outer conductor 7 and the cavity wall of the docking cavity 24, enabling the bottom end of the outer conductor 7 to move in any direction in the transverse plane of the docking cavity 24. The limiting portion 26 is preferably arranged perpendicular to the cavity wall of the docking cavity 24, so as to achieve the best limiting effect.

[0038] By providing a gap X between the outer conductor and the cavity wall of the docking cavity, the bottom end of the outer conductor can move in any direction within the transverse plane of the docking cavity, thereby effectively correcting a large position offset and achieving a large mating tolerance. At the same time, the vehicle-mounted line-end floating connector has fewer components and is easy to install, effectively improving production efficiency.

A plurality of outwardly protruding locking portions 221 are provided on the periphery of the docking portion 22 of the camera rear shell 2. The locking portions 221 cooperate with the stepped portion 322 to form a locking structure, which can cooperate with the external thread 321 to achieve a more stable connection between the docking portion 22 and the sealing cover 3. A plurality of elastic sheet portions 27 are further protruded inward and downward from the upper part of the docking cavity 24, and the sheet portions 27 play a protective role for the outer conductor 7.

[0041] Further, referring to Figure 2 As shown, the lower end of the floating conductor 6 has a plurality of petal-shaped elastic pieces 61. There are through grooves 62 between the petal-shaped elastic pieces 61, and a plurality of concave portions 63 are further provided above the petal-shaped elastic pieces 61. The locking portion 53 on the insulator 5 can be locked in the through groove 62, and an interference connection is formed between the concave portion 63 and the insulator 5, thereby improving the stable connection between the floating conductor 6 and the insulator 5.

[0042] Further, referring to Figure 9 As shown, the periphery of the bottom of the insulator 5 has a shielding umbrella portion 51 arranged along its circumference, a guiding portion 52 at the center of the bottom, and locking portions 53 recessed outward at intervals along the circumference of the middle section. Among them, the shielding umbrella portion 51 extends outside the lower end of the floating conductor 6, that is, the shielding umbrella portion 51 is located below the petal-shaped elastic pieces 61 in the longitudinal direction to protect the petal-shaped elastic pieces 61 during mating and prevent them from being deformed and damaged. A guiding structure 511 is also provided on the shielding umbrella portion 51, which can guide the petal-shaped elastic pieces 61 to be smoothly inserted into the cavity 911 of the outer shell 91, and the guiding portion 52 can guide the center pin 93 to be smoothly inserted into the center conductor 4.

[0043] Further, referring again to Figure 2 As shown, a plurality of barbs 41 are provided on the periphery of the center conductor 4, and the barbs 41 are used to interfere-fix the center conductor 4 on the insulator 5, thereby improving the stability of the connection between the center conductor 4 and the insulator 5.

[0044] Further, with reference to Figure 3 As shown, sealant is coated on both the first connection part 33 between the sealing cover 3 and the cable body 81 and the second connection part 34 between the sealing cover 3 and the rear camera housing 2, so as to achieve a good waterproof function.

[0045] The installation steps of the in-vehicle line-end floating connector 100 in the embodiment of the present invention are as follows:

[0046] 1. Install the sealing cover 3 on the cable body 81 of the cable assembly 2;

[0047] 2. Rivet the center conductor 4 to the core wire 82 of the cable assembly 8;

[0048] 3. Insert the insulator 5 into the floating conductor 6, so that the shielding umbrella part 51 of the insulator 5 extends outside the petal-shaped elastic piece 61;

[0049] 4. Rivet the floating conductor 6 to the shielding layer 83 and the cable sleeve 84 of the cable assembly 8;

[0050] 5. Install the outer conductor 7 outside the floating conductor 6 to form an assembly;

[0051] 6. Insert the assembly into the rear camera housing 2;

[0052] 7. Fix the connection between the sealing cover 3 and the rear camera housing 2.

[0053] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0054] The above-described embodiments only express the implementation manners of the present invention, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
