Description

Technical Field

[0001] The utility model belongs to the technical field of composite poles, and in particular relates to a low-cost press-riveted self-fastening copper-aluminum composite pole. Background Art

[0002] The cover plate pole of new energy batteries is an important component of new energy batteries. The cover plate pole of the battery is a key part that connects the internal battery cells with the external circuit. It mainly plays the role of conducting current, outputting the electric energy generated inside the battery to external devices or circuits. The pole is usually made of metal materials with good conductivity, such as copper, aluminum, etc.; in new energy batteries, the performance of the cover plate pole has an important impact on the overall performance and safety of the battery. It needs to have good conductivity, corrosion resistance and mechanical strength to ensure stable and reliable current transmission, while being able to remain stable under various use environments, and being able to withstand certain external force impacts without damage. It is also one of the key parts of battery sealing, and it also plays a vital role in preventing leakage of internal battery substances and ensuring safe operation of the battery.

[0003] In the existing copper-aluminum composite pole industry, the existing process of the negative pole structure is to stamp the composite plate blank by machining or friction welding. There are several disadvantages: not only will it cause low raw material utilization, but it will also affect its processing technology, resulting in high manufacturing costs, and the copper surface machining (sealing ring fitting surface) is prone to tilting due to multiple clamping, and the thickness and symmetry of the residual aluminum layer are different, resulting in low yield and poor product consistency.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0005] In view of the problems in the related art, the utility model proposes a low-cost press-riveted self-fastening copper-aluminum composite pole to overcome the above-mentioned technical problems existing in the existing related art.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a low-cost self-clinching copper-aluminum composite pole, comprising a cover plate, a first plastic ring is arranged inside the cover plate, and a second plastic ring is symmetrically arranged with the first plastic ring on the other side of the cover plate, a first negative pole is arranged on the central axis of the first plastic ring and the second plastic ring, a second negative pole is arranged below the cover plate and below the first negative pole, and the second negative pole is buckled with the first plastic ring and the second plastic ring to form an inverted limit, a sealing ring is arranged between the first negative pole and the second negative pole, and the first plastic ring and the second plastic ring can fix the cover plate, the first negative pole and the sealing ring.

[0008] Furthermore, a first rivet groove is provided on the first negative electrode column, and a second rivet is fixedly installed on the bottom of the first negative electrode column.

[0009] Furthermore, a second rivet groove is formed on the second negative electrode column, and the second rivet groove and the second rivet are engaged with each other.

[0010] Furthermore, a first rivet is fixedly installed on the top of the second negative electrode column, and the first rivet is engaged with the first rivet groove.

[0011] Furthermore, an inverted cone block is fixedly installed on the outer side of the top of the second negative electrode column, and the inverted cone block forms an inverted buckle with the first plastic ring and the second plastic ring.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model forms an inverted limiter through the first plastic ring and the second plastic ring, thereby improving the tightness of the connection between the cover plate, the first plastic ring, the second plastic ring, and the first negative pole. Furthermore, through the mutual cooperation between several simple and common cover plates, the first plastic ring, the second plastic ring, and the first negative pole, the tightness of the connection is achieved, thereby solving the problems of low raw materials, complex processing technology and high cost.

[0014] 2. The utility model achieves fixation and sealing between the cover plate, the first negative pole and the sealing ring through the first plastic ring and the second plastic ring, so that the structural manufacturing consistency is high, and the problems of low seismic strength and unreliable sealing in the existing device are solved. The cover plate, the first negative pole and the sealing ring are simply matched with the first plastic ring and the second plastic ring, so that the effect of high seismic strength and reliable sealing can be achieved, thereby avoiding the problems of copper surface machining, namely: the sealing ring fitting surface is prone to tilting after multiple clamping, the thickness symmetry difference of the residual aluminum layer is low, the yield is low, and the product consistency is poor.

[0015] 3. The utility model forms an inverted buckle when the outer inverted cone of the inverted cone block on the second negative pole is injected with the first plastic ring and the second plastic ring to ensure that the pole does not move and the sealing stability is guaranteed.

[0025] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements 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 utility model.

[0027] See also Figure 1-Figure 5As shown, the utility model is a low-cost self-clinching copper-aluminum composite pole, including a cover sheet 1, a first plastic ring 2 is arranged inside the cover sheet 1, and a second plastic ring 3 is symmetrically arranged with the first plastic ring 2 on the other side of the cover sheet 1, a first negative pole 4 is arranged on the central axis of the first plastic ring 2 and the second plastic ring 3, and a second negative pole 5 is arranged below the cover sheet 1 and below the first negative pole 4, and the second negative pole 5 is inverted with the first plastic ring 2 and the second plastic ring 3 to form an inverted limit, and a sealing ring 6 is arranged between the first negative pole 4 and the second negative pole 5, and the first plastic ring 2 and the second plastic ring 3 can fix the cover sheet 1, the first negative pole 4, and the sealing ring 6.

[0028] The cover sheet 1 and the first negative electrode column 4 are connected through the first plastic ring 2 and the second plastic ring 3. At the same time, the second negative electrode column 5 is in an inverted state and forms an inverted limit with the first plastic ring 2 and the second plastic ring 3, so as to improve the tightness of the connection between the cover sheet 1, the first plastic ring 2, the second plastic ring 3, and the first negative electrode column 4. In addition, the cover sheet 1, the first negative electrode column 4, and the sealing ring 6 are fixed and sealed through the injection molding connection of the first plastic ring 2 and the second plastic ring 3.

[0029] Thereby, the first plastic ring 2 and the second plastic ring 3 form an inverted limit stop, thereby improving the tightness of the connection between the cover plate 1, the first plastic ring 2, the second plastic ring 3, and the first negative electrode column 4. Through the mutual cooperation of several simple and common cover plates 1, the first plastic ring 2, the second plastic ring 3, and the first negative electrode column 4, the tightness of the connection between them is achieved, thereby solving the problems of low raw materials, complex processing technology and high cost.

[0030] Thus, the cover sheet 1, the first negative pole 4, and the sealing ring 6 are fixed and sealed by the first plastic ring 2 and the second plastic ring 3, so that the structural manufacturing consistency is high, and the problems of low seismic strength and unreliable sealing in the existing device are solved. The cover sheet 1, the first negative pole 4, and the sealing ring 6 can achieve high seismic strength and reliable sealing by simply matching the first plastic ring 2 and the second plastic ring 3, thereby avoiding the problems of copper surface machining, namely: the sealing ring 6 fitting surface is prone to tilting after multiple clamping, the thickness symmetry difference of the residual aluminum layer is low, the yield is low, and the product consistency is poor.

[0031] In addition, in specific applications, the cover sheet 1 is preferably made of aluminum, the first negative electrode column 4 is preferably made of a copper-aluminum composite material, and the first plastic ring 2 and the second plastic ring 3 are preferably injection-molded PPS materials.

[0032] In one embodiment, for the first negative electrode column 4 , a first rivet groove 401 is provided on the first negative electrode column 4 , and a second rivet 402 is fixedly installed on the bottom of the first negative electrode column 4 .

[0033] A second rivet groove 501 is formed on the second negative electrode column 5 , and the second rivet groove 501 and the second rivet 402 are engaged with each other.

[0034] A first rivet 502 is fixedly mounted on the top of the second negative electrode column 5 , and the first rivet 502 is engaged with the first rivet groove 401 .

[0035] The first negative electrode column 4 and the second negative electrode column 5 are self-locked through the first rivet groove 401 and the first rivet 502, and the second rivet 402 and the second rivet groove 501. Since aluminum has better fluidity than copper, aluminum is reserved to bite the second rivet groove 501 and the first rivet 502 during pressing, thereby achieving self-locking.

[0036] In one embodiment, for the second negative electrode column 5 , an inverted cone block 503 is fixedly installed on the outer side of the top of the second negative electrode column 5 , and the inverted cone block 503 forms an inverted buckle with the first plastic ring 2 and the second plastic ring 3 .

[0037] Then the outer inverted cone of the inverted cone block 503 fixedly mounted on the second negative pole 5 can form an inverted buckle with the first plastic ring 2 and the second plastic ring 3 during injection molding, ensuring that the pole does not move and ensuring sealing stability.
