Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to an energy storage connector. Background Art

[0002] Energy storage connectors are used to connect battery packs within energy storage systems, as well as between battery packs and external circuits. Their primary function is to ensure the efficient and safe transmission of electrical energy. Energy storage connectors play a vital role in energy storage systems, such as battery energy storage systems, particularly in applications such as electric vehicles, renewable energy generation systems, grid energy storage, and uninterruptible power supplies (UPS).

[0003] However, existing energy storage connectors usually adopt an integral structure, which means that if a component needs to be repaired or replaced, the entire connector needs to be disassembled and replaced, which greatly increases maintenance costs and time.

[0004] Secondly, due to the limitations of processing technology, energy storage connectors are difficult to produce in small batches, which makes the production cost higher. Summary of the Invention

[0005] The purpose of the present invention is to provide an energy storage connector with high stability and compact structure in order to solve the above problems in the prior art.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A energy storage connector includes a base with a hollow interior, a connecting copper column fixedly connected to the base, and is characterized in that it also includes a cover plate, which is snapped onto the base and has a snap-fit assembly between the two. The cover plate and the base can be positioned and connected through the snap-fit assembly. The lower portion of the cover plate has a recessed avoidance hole. When the inner end of the cold-pressed terminal is connected to the connecting copper column, the cold-pressed terminal is inserted into the avoidance hole.

[0008] In the above energy storage connector, the interior of the cover plate is a cavity and the lower end is open, and the avoidance hole is located at the lower end of the cover plate.

[0009] In the above-mentioned energy storage connector, the snap-fit assembly includes a protruding head protruding from the base and an elastic card protruding from the side of the cover. The card has a card hole matching the protruding head. When the cover is snapped onto the base, the protruding head is embedded in the card hole.

[0010] In the above energy storage connector, the cover plate and the card are an integrated structure and are made of insulating plastic material.

[0011] In the above energy storage connector, there are two cards, which are symmetrically distributed on both sides of the cover plate, and the base has protrusions corresponding to the cards one by one.

[0012] In the above energy storage connector, the number of the avoidance hole is one.

[0013] In the above energy storage connector, the number of the avoidance holes is two, and the two avoidance holes are symmetrically distributed on both sides of the cover plate.

[0014] In the above energy storage connector, the outer side of the base has a protruding connecting edge, and the connecting edge has a positioning hole penetrating therethrough and used for connecting a fastener.

[0015] The energy storage connector further comprises an arc-shaped shield, the inner end of the shield is fixedly connected to the cover plate and the two are in communication, and the lower end of the shield is fixedly connected to the connecting edge.

[0016] In the above energy storage connector, the protective cover, the connecting edge and the cover plate are all integrated structures.

[0017] Compared with the prior art, the energy storage connector can be easily and quickly disassembled from the cover and the base after external force is applied. Therefore, after the cover is removed, the cold-pressed terminal can be conveniently connected to the base. Of course, after the cover is overlapped and fastened to the base, the inner end of the cold-pressed terminal can be stably covered, and the entire energy storage connector is easy to use.

[0018] At the same time, there are avoidance holes on both sides of the cover, so the wires can be output in both directions, that is, two cold-pressed terminals can be conveniently connected on this connector, which has high applicability.

[0019] In addition, since the inner end of the cold-pressed terminal is covered between the base and the cover, it can also avoid accidental contact at the electrical connection, effectively improving safety and having high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1 and Figure 2 As shown, the energy storage connector includes a base 1 with a hollow interior, a connecting copper column 2 fixedly connected to the base 1, and a cover plate 3. The cover plate 3 is snapped onto the base 1 with a snap-fit assembly between the two. The snap-fit assembly enables the cover plate 3 to be positioned and connected to the base 1. The lower part of the cover plate 3 has a recessed avoidance hole 3a. When the inner end of the cold-pressed terminal 4 is connected to the connecting copper column 2, the cold-pressed terminal 4 is inserted into the avoidance hole 3a.

[0027] The base 1 and the cover 3 are both made of insulating materials, and the connection copper pillar 2 is connected inside the base 1 to provide good protection for the connection copper pillar 2 .

[0028] Under the action of the buckling assembly, the cover plate 3 can be stably buckled and connected to the base 1.

[0029] Due to the presence of the avoidance hole 3a, when the inner end of the cold terminal 4 is connected to the connecting copper column 2, the inner end of the cold terminal 4 is covered between the cover 3 and the base 1. At the same time, the cold terminal 4 can also be stably led out of the entire energy storage connector.

[0030] The cover plate 3 is hollow inside and open at the lower end. The avoidance hole 3 a is located at the lower end of the cover plate 3 .

[0031] Such a structure enables the cover 3 to be stably fastened and connected to the base 1 .

[0032] The snap-fit assembly includes a protruding head 1a protruding from the base 1 and an elastic card 3b protruding from the side of the cover 3. The card 3b has a card hole 3b1 that matches the protruding head 1a. When the cover 3 is snapped onto the base 1, the protruding head 1a is embedded in the card hole of the card 3b.

[0033] After the protrusion 1a is inserted into the card hole 3b1 of the card 3b, the cover 3 and the base 1 can be stably fastened together.

[0034] The cover plate 3 and the card 3b are an integrated structure and are made of insulating plastic material.

[0035] This can appropriately improve the compactness of the structure, and the plastic material can enable the cover plate 3 to be formed in one step through an injection molding operation.

[0036] There are two cards 3b, which are symmetrically distributed on both sides of the cover. The base 1 has protrusions 1a corresponding to the cards 3b one by one.

[0037] The arrangement of the two cards 3 b enables the cover 3 and the base 1 to be connected together more stably.

[0038] The number of the avoidance hole 3a is one.

[0039] According to actual conditions, another solution may be adopted, that is, the number of the avoidance holes 3 a is two, and the two avoidance holes 3 a are symmetrically distributed on both sides of the cover plate 3 .

[0040] One avoidance hole 3a can simplify the entire energy storage connector structure, and two symmetrically arranged avoidance holes 3a can improve its applicability, that is, the two cold-pressed terminals 4 can be stably connected to the connecting copper columns 2 of the base 1 through the corresponding avoidance holes 3a.

[0041] The base 1 has a protruding connecting edge 1b on the outside, and the connecting edge 1b has a positioning hole penetrating therethrough for connecting a fastener.

[0042] The energy storage connector can be stably connected to the corresponding bracket by connecting the fasteners at the edge 1b.

[0043] It also includes an arc-shaped shield 3c, the inner end of which is fixedly connected to the cover plate 3 and the two are in communication, and the lower end of the shield 3c is fixedly connected to the connecting edge 1b.

[0044] Shield 3c has two functions:

[0045] First, the avoidance hole 3a weakens the strength of the cover plate 3, but the additional shield 3c indirectly improves the strength of the entire cover plate 3;

[0046] Secondly, the inner end of the cold-pressed terminal 4 can be kept as far away from the outer side of the energy storage connector as possible, so as to avoid the connection part of the cold-pressed terminal 4 from being exposed.

[0047] The protective cover 3c, the connecting edge 1b and the cover plate 3 are all integrated structures.

[0048] This can appropriately improve the structural compactness of the entire energy storage connector.

[0049] This assembled energy storage connector includes a detachable cover, a base, and a connecting copper column. Since the connecting copper column is located inside the base, it can effectively protect the connecting copper column. The cover is stably connected to the base through a snap-on assembly.

[0050] It can be seen that the above-mentioned assembly structure makes maintenance and replacement of parts more convenient and quick. It can ensure a tight connection between the cover and the base to avoid current leakage, and can be stably fixed on the main body of the energy storage connector while maintaining electrical contact with other components. In addition, the simple and novel design of the connector socket makes the installation process convenient and quick, while also ensuring the safety of use. The top of the connecting copper column is fixed in the base, and the bottom extends to the outside of the connector plug. This design not only solves the problem of affecting current carrying, but also solves the problem of cumbersome processing technology. The bottom extension of the connecting copper column can be connected to other connectors or power supply equipment to form a current path. This design not only improves the maintainability of the equipment, but also reduces production costs.

[0051] The various technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments fall within the scope of protection claimed by the present invention.
