Description

Technical Field

[0001] The utility model relates to the field of information transmission of electronic products, in particular to a CCS integrated busbar with a novel protective cover fixing device. Background Art

[0002] CCS integrated busbars are commonly used in new energy vehicles and energy storage battery modules to connect battery cells in series and parallel, sample temperature and voltage, and transmit this information to the BMS. The CCS integrated busbar requires a protective cover to be fixed to the outside. The current assembly method involves positioning the CCS and protective cover, then inserting several pins (a dozen or more) to secure the busbar. This method has several drawbacks: First, the pins are too short, making them difficult to remove, making installation difficult, labor-intensive, and time-consuming. Second, the use of pins can easily lead to assembly failures, reducing product yield. Utility Model Content

[0027] The present invention will be described in further detail below with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0028] Figures 1 to 6 The schematic diagram shows a CCS integrated busbar with a novel protective cover plate fixing device according to one embodiment of the present invention. As shown in the figure, the CCS integrated busbar with the novel protective cover plate fixing device includes: a plurality of fixing devices 1, a CCS body 01, and a protective cover plate 02;

[0029] The fixture 1 comprises a circular base column 10, with a lower positioning cap 11 of increasing diameter at its lower end and an elastic column 12 of decreasing diameter at its upper end. The upper end of the elastic column 12 further increases in diameter to form an upper positioning cap 13. Preferably, an elastic clearance hole 14 is formed in the center of the elastic column 12, extending through the upper positioning cap 13 and to the end of the elastic column 12. The elastic clearance hole 14 is preferably in the shape of a straight line or a cross. The fixture 1 is preferably made of an elastic material, such as elastic plastic or rubber.

[0030] The aluminum bars 2 on the four sides and in the middle of the CCS body 01 are provided with lower connection holes 21. The aluminum bars 2 are attached to the upper surface of the lower positioning end cover 11 and the lower connection holes 21 are connected to the base column 10 through the interference sleeve, so that the aluminum bars 2 and the fixture 1 become one.

[0031] Protective cover 02 is provided with several upper connection holes 020 positioned in the same order as lower connection holes 21. Protective cover 02 is preferably made of plastic. Place protective cover 02 on CCS body 01, aligning each upper connection hole 020 with an upper positioning end cap 13. Apply pressure to protective cover 02, causing the upper positioning end cap 13 to deform through the upper connection hole 020 and position itself above protective cover 02. Elastic column 12 then sleeves into the upper connection hole 020, effectively connecting protective cover 02 and CCS body 01.

[0032] The CCS integrated busbar with a new protective cover fixing device adopts a new type of fixer 1 to be crimped and fixed to the aluminum bar in advance. The protective cover 02 and the CCS main body 01 are directly aligned, and the connection between the two can be achieved by directly pressing. Its beneficial effects are: First, the workers of this device only need to align and press to complete the assembly, which effectively reduces the difficulty of installation, and the assembly is simple and time-saving, with high assembly efficiency. At the same time, it avoids product defects caused by assembly errors and has a high product yield; second, the fixer 1 adopts a direct interference connection with the aluminum bar, in which high-precision connection is achieved through the lower positioning end cover 11, and accurate positioning and upper limit constraint are achieved through the upper positioning end cover 13, thereby effectively realizing the precise fixation of the CCS integrated busbar and the protective cover; third, through the elastic deformation of the elastic column 12 and the upper positioning end cover 12, the protective cover 02 can be easily entered and axially constrained and fixed.

[0033] Preferably, the upper end surface of the upper positioning end cap 13 is provided with a first chamfer 15 that facilitates insertion into the upper connection hole 020, thereby giving the upper positioning end cap 13 a frustum-shaped shape. This advantageously allows the upper positioning end cap 13 of the fixture 1 to pass through the protective cover 02, facilitating assembly of the CCS body 01 and the protective cover 02 while allowing for a certain degree of positional deviation.

[0034] Furthermore, the diameter of the upper positioning end cap 13 is larger than the upper connection hole 020 and smaller than the diameter of the base column 10. After the upper positioning end cap 13 passes through the lower connection hole 21, the base column 10 is interference-connected with the lower connection hole 21 of the aluminum bar 2. The beneficial effect is that this arrangement can effectively fix the aluminum bar 2 and the protective cover plate 02.

[0035] Preferably, the upper end of the base column 10 is provided with a second chamfer 16 for easy insertion into the lower connection hole 21. The beneficial effect is that this setting can guide the base column 10 into the hole of the aluminum bar 2, facilitate the assembly of the aluminum bar 2 and the protective cover 02, and allow a certain position deviation.

[0036] Preferably, a first rounded corner 17 is provided between the elastic column 12 and the upper positioning end cap 13, and a second rounded corner 18 is provided on the lower end edge of the lower positioning end cap 11. The beneficial effect is that the rounded corners can avoid damaging the film and related parts.

[0037] Preferably, the upper wall plate of the protective cover plate 02 is gap-connected between the upper positioning end cover 13 and the upper surface of the base column 10 .

[0038] The distance between the lower positioning end cap 11 and the upper positioning end cap 13 of the fixture 1 is greater than the sum of the thicknesses of the CCS body 01 and the protective cover 02. The beneficial effect is that this arrangement facilitates connection and has a certain tolerance rate.

[0039] Furthermore, the combination of the aluminum bar 2 and the fixture 1 is assembled with the FPC flexible circuit board 3 and the NTC bracket, and then the insulating film 4 and the lower insulating film 5 are attached to the upper and lower surfaces and hot-pressed to form the CCS body 01.

[0040] Preferably, the outer surface of the holder 1 is provided with a bright color that is easy to identify, so as to distinguish and identify the holder 1 from the CCS body 01 and facilitate positioning.

[0041] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
