Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of integrated busbar, especially a novel CCS integrated busbar structure. BACKGROUND

[0002] The super capacitor module is a new type of energy storage device between the traditional capacitor and the charging battery, has the advantages of fast charging speed, long service life, strong large current discharge capacity, non-pollution use and is widely used in the electric car field.

[0003] The existing super capacitor module is generally matched with an integrated busbar, which includes an isolation plate and a plurality of conductive rows arranged on the isolation plate, one end of the conductive row is connected with the positive pole of one capacitor, and the other end is connected with the negative pole of another capacitor, so as to realize the series connection of the plurality of capacitors. The busbar and the super capacitor cannot balance the voltage difference between the adjacent capacitors, which may cause overvoltage of some capacitors, affecting the service life and safety. Therefore, how to design a novel CCS integrated busbar structure capable of balancing the capacitor voltage and service life has become a technical problem to be solved. UTILITY MODEL CONTENT

[0004] In order to overcome the technical defects of the prior art, the utility model aims to provide a novel CCS integrated busbar structure to solve the above technical problems.

[0005] The technical solution adopted by the utility model to solve the technical problems is as follows:

[0006] According to one aspect of the utility model, a novel CCS integrated busbar structure is designed, which comprises: an isolation plate and a plurality of conductive rows arranged on the top of the isolation plate, a positive pole end row and a negative pole end row, the isolation plate is provided with through holes for exposing the positive pole column and the negative pole sheet on the upper end of the capacitor unit, one end of each conductive row is provided with two positive pole connecting ends, and the other end is provided with two negative pole connecting ends, the positive pole connecting end and the negative pole connecting end on each conductive row are arranged one by one above and below the through hole, respectively, the two positive pole connecting ends on one of the two adjacent conductive rows in the plurality of conductive rows are arranged in the two negative pole connecting ends on the other, and form a conductive row group, the two positive pole connecting ends on the positive pole end row are arranged in the two negative pole connecting ends at one end of the conductive row group, and the two positive pole connecting ends at the other end of the conductive row group are arranged in the two negative pole connecting ends on the negative pole end row.

[0007] Using the above technical solution, the novel CCS integrated busbar structure of this technical solution is used on supercapacitors. The two positive terminals at one end of the busbar can be electrically connected to the positive terminals of two capacitor units, and the two negative terminals at the other end can be electrically connected to the negative terminals of two other capacitor units. This allows several capacitor units to form a series capacitor structure through the busbar. The busbar can balance the voltage difference between adjacent capacitors, prevent overvoltage in some capacitors, and thus improve the stability, safety and service life of the supercapacitor.

[0008] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0009] In some embodiments, the top of the isolation plate is provided with a mounting groove for inserting the conductive busbar. The bottom of the mounting groove is provided with a positioning post, and the side wall is provided with a limiting protrusion to restrict the upward movement of the conductive busbar. The conductive busbar is provided with a strip-shaped hole that cooperates with the positioning post and allows for lateral fine-tuning of the conductive busbar. When the conductive busbar is placed in the mounting groove, the limiting protrusion restricts its upward movement, facilitating subsequent welding between the conductive busbar and the capacitor unit. The strip-shaped hole allows for lateral fine-tuning of the conductive busbar's position, ensuring that the positive and negative connection terminals on the conductive busbar accurately align with the capacitor unit, ensuring precise alignment of the positive terminal and the insertion hole, and avoiding welding deviations.

[0010] In some embodiments, the positive terminal of the conductive busbar and the positive terminal of the positive terminal busbar are respectively provided with insertion holes for inserting the positive terminal post at the top of the capacitor unit.

[0011] In some embodiments, the isolation plate is provided with several sets of cable tie holes for binding the wire harness with cable ties.

[0012] In some embodiments, a 45° bevel is provided at the lower opening of the insertion hole. The bevel facilitates the insertion of the positive terminal of the capacitor unit into the insertion hole, improving assembly efficiency.

[0013] In some embodiments, the conductive bus, positive terminal bus, and negative terminal bus are each provided with at least one terminal locking hole for mounting a terminal. When it is necessary to connect the terminal to the conductive bus, the locking part of one end of the terminal is inserted into the terminal locking hole to position and limit the terminal, facilitating subsequent welding of the terminal to the conductive bus using automated welding equipment.

[0014] In some embodiments, the negative terminal on the conductive busbar and the negative terminal on the negative terminal block are both semi-circular structures.

[0015] In some implementations, at least two terminals are connected to the positive terminal block and the negative terminal block, respectively. Attached Figure Description
