The features and capabilities of the present application are described in further detail below in connection with the examples.
Specific embodiment 1 of floating structure of floating connector of the present invention:
as shown in fig. 1 to 10, the floating structure of the floating connector includes a fixed housing 11, a cover plate 12, a floating housing 13, a circumferential spring 14, and a floating spring 15.
As shown in fig. 1, 2, 3, 5, 6 and 7, the outer contour of the fixing housing 11 in this embodiment is rectangular, and includes surrounding walls and a channel 111 in the middle of the front side, and the channel 111 runs through from front to back. The rear side of the enclosure wall is provided with a pallet 112 at each of four corners, the pallet 112 extending into the channel 111. A connection structure, specifically a connection lug plate 113, is provided on the outside of the surrounding wall for fixedly connecting with a member using the floating connector, such as a battery box or a battery compartment of an electric vehicle.
As shown in fig. 6, 7 and 9, the cover 12 has a square outer shape, and is fixedly mounted on the front side of the fixed housing 11 by a fixing screw 16, and an opening 121 is provided in the middle of the cover.
As shown in fig. 2, 3, 5, 6, 7 and 8, the floating housing 13 may be mainly referred to fig. 8, the cross section of the floating housing 13 is rectangular, and is installed in the channel 111 of the fixed housing 11, and cantilever arms 131 extending radially to the outside are provided at four corners on the outer wall of the floating housing 13, and the cantilever arms 131 are in a blocking engagement with the cover plate 12, so that the floating housing 13 is prevented from being separated from the front end of the fixed housing 11. As shown in fig. 2, 3, 5, 6 and 7, the cross-sectional dimension of the floating housing 13 is smaller than the dimension of the channel and the dimension of the opening 121 in the cover 12, so that after the installation, a floating space is formed between the floating housing 13 and the channel 111 and between the floating housing and the inner wall of the opening 121 in the cover 12, and the floating housing can be moved to any direction around.
As shown in fig. 2, 3, 4, 6, 7, 8, the circumferential spring 14 is installed in the circumferential direction of the floating housing 13, and is thus named. The circumferential spring 14 is connected between the outer wall surface of the floating housing 13 and the inner wall surface of the fixed housing 11, and is used for driving the floating housing 13 to return to the fixed housing 11, in this embodiment, the circumferential spring 14 is horizontally disposed, and of course, in other embodiments, the circumferential spring 14 may also have a certain angle with the horizontal plane. Theoretically, as long as the circumferential springs 14 are provided on opposite sides of the floating housing 13, the floating housing 13 can be driven to return to the fixed housing 11, and the circumferential springs 14 may be tension springs or compression springs. In the present embodiment, the circumferential springs 14 are tension springs, the circumferential springs 14 are provided at opposite sides thereof, respectively, the circumferential springs 14 located at the same side of the floating housing 13 are provided in pairs, and the circumferential springs of the same pair are arranged in a splayed manner, and in the present embodiment, only one pair of circumferential springs are provided at the same side of the floating housing 13 in an in-splayed manner, that is, the interval between the ends of the two circumferential springs connected with the floating housing 13 is larger than the interval between the ends connected with the fixed housing 11. For connection with the circumferential spring 14, an outer connection seat 132 is provided on the outer wall of the floating housing 13, and connection of the floating housing 13 with the circumferential spring 14 is achieved by mounting the first pin 17 on the outer connection seat 132.
As shown in fig. 3, 6 and 7, for connection with the circumferential spring 14, the fixed housing 11 is provided with an inner connection base 114 and a second pin 18, and as shown in fig. 9, the second pin 18 is fixedly provided on the cover plate 12, and when the cover plate 12 is fixed with the fixed housing 11, the second pin 18 is inserted into the corresponding inner connection base 114, thereby connecting the circumferential spring 14 with the fixed housing 11.
As shown in fig. 2, 3, 5, 6, 7 and 8, four floating springs 15 are arranged between the fixed shell 11 and the floating shell 13 in a top-mounted manner, specifically, are positioned at four corners of the floating shell 13 corresponding to the fixed shell 11, the lower ends of the floating springs 15 are arranged on a supporting plate 112 of the fixed shell 11, and a supporting plate positioning block 115 for positioning the floating springs 15 is arranged on the supporting plate 112; cantilever 131 of floating housing 13 is provided with cantilever positioning blocks 133 that mate with the front ends of floating springs 15. In order to be able to drive floating housing 13 back towards fixed housing 11, floating springs 15 are arranged obliquely, and the faces of the pallets and cantilevers at both ends of the same floating spring 15 that mate with the floating springs are perpendicular to the floating springs.
The front side surface of the cantilever 131 on the floating shell 13 is tightly attached to the cover plate 12 due to the pushing action of the floating spring 15; as shown in fig. 5, 6, 7 and 9, a self-lubricating pad 19 is disposed at a position of the cover plate 12 matching with the cantilever 131, the self-lubricating pad 19 is structured as shown in fig. 7, 9 and 10, a plug 191 and a rotation stopping groove 192 are disposed at the front side of the self-lubricating pad 19, an elastic barb is disposed on the plug 191, a jack 122 corresponding to the plug 191 and a rotation stopping block 123 corresponding to the rotation stopping groove 192 are disposed on the cover plate 12, in this embodiment, the plug 191 adopts a split structure, the elastic barb is formed by each split part, when the plug 191 is aligned with a corresponding jack on the cover plate 12, and the rotation stopping groove corresponds to a corresponding rotation stopping block 123 on the cover plate, so that the self-lubricating pad 19 can be quickly mounted on the cover plate 12. In order to further limit the self-lubricating pad, a positioning groove 124 corresponding to the self-lubricating pad 19 is also provided on the inner side surface of the cover plate 12. In addition, the inner side surface of the cover plate 12 is also provided with a limit rib 125 at the periphery of the self-lubricating pad 19, and the limit rib 125 is provided with a rib block 126 matched with the outer edge of the self-lubricating pad 19, so that the self-lubricating pad 19 can be better limited. In order to form a certain limit and centering assistance with the cantilever of the floating housing 13, a chute 193 matched with the cantilever 131 of the floating housing 13 is also arranged on the self-lubricating pad 19.
When the floating structure of the floating connector is used for the floating connector, the fixed shell 11 can be fixedly installed on a corresponding component (such as a battery box/a battery bin) when the floating connector is used, when the floating connector is plugged with an adaptive connector under the condition of deviation, the floating shell 13 can overcome the elasticity of the circumferential spring 14 and the floating spring 15, and the deviation is compensated by the movement of the floating shell relative to the fixed shell 11, so that smooth plugging is realized; when separated from the mating connector, the floating housing 13 is retracted under the dual action of the floating spring 15 and the circumferential spring 14. Since the force provided by the circumferential spring 14 is mainly in the horizontal direction throughout the process, it actually forms a supplement to the centering force of the floating spring 15, and together with the lubricating effect of the self-lubricating pad 19, it will contribute to reliably achieving centering of the floating housing.
The above description is only a preferred embodiment of the present application, and is not intended to limit the present application, and the patent protection scope of the present application is defined by the claims, and all equivalent structural changes made by the specification and the attached drawings of the present application should be included in the protection scope of the present application.
