With the development of energy storage technology, energy storage devices will be widely used in power systems, new energy vehicles, smart homes, data centers, and many other fields, providing strong support for energy transition and sustainable development.

[0003] To ensure stable operation of energy storage devices, their internal wiring, such as PIN connectors and flexible flat cables, typically requires high connection strength. Therefore, this connection strength often becomes a key factor limiting the stable operation of energy storage devices. However, a major problem with existing internal wiring technology is insufficient connection strength. When users accidentally pull on the internal wiring or when it is subjected to external impact, the connection end of the wiring body can easily detach from the outer casing. Consequently, the energy storage device will be unable to supply power or transmit data normally, causing system malfunctions and affecting the overall performance and reliability of the equipment. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a reinforced PIN connector and energy storage device that prevents internal wiring from falling out of the connector housing and ensures the stability of the wiring.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0031] Please see Figures 1 to 6This is an embodiment of the reinforced PIN connector 10 of the present invention, comprising a PIN wire body 100 and two connecting structures 200. The PIN wire body 100 is used for electrically connecting to the motherboard of the energy storage device, including a middle part 110 and two power receiving parts 120, which are respectively connected to the two ends of the middle part 110. Each connecting structure 200 includes a connecting shell 210, a snap fastener 220, and an anti-detachment piece 230. The connecting shell 210 has an installation channel 2101. Each power receiving part 120 has multiple gold fingers, and each power receiving part 120 is located in the corresponding installation channel 2101. The connecting shell 210 also has an abutment grille 211, which is connected to the bottom of the installation channel 2101. The device has multiple grille openings 2111, and the power receiving part 120 also abuts against the grille 211. Each gold finger is positioned facing the corresponding grille opening 2111 so that the gold finger is exposed to the outside. A latching block 212 protrudes from the outer side of the connecting housing 210. The latching part 220 includes a latching cover 221 and a latching plate 222 connected to each other. The latching cover 221 has a latching groove 221a. The latching block 212 is located in the latching groove 221a, and the latching plate 222 is located in the mounting channel 2101. An anti-detachment piece 230 is located in the mounting channel 2101. Both sides of the anti-detachment piece 230 are respectively press-fitted against one side of the latching plate 222 and one side of the power receiving part 120 so that the power receiving part 120, the anti-detachment piece 230 and the latching plate 222 together press-fit to fill the mounting channel 2101.

[0032] In this embodiment, the reinforced PIN connector 10 has a strong connection structure 200. Specifically, an anti-detachment piece 230 is added to the assembled PIN connector. Since the end of the PIN body 100 and the snap plate 222 are both located in the installation channel 2101, the anti-detachment piece 230 is used to fill the gap between the end of the PIN body 100 and the snap plate 222. This allows the structure formed between the end of the PIN body 100, the anti-detachment piece 230, and the snap plate 222 to over-fill the installation channel 2101, thereby enhancing the connection strength between the PIN body 100 and the connection structure 200. This makes it less likely for the PIN body 100 to fall off, ensuring the stability of the wiring inside the device, and thus ensuring the overall performance and reliability of the device.

[0033] In another embodiment, the snap cover 221 and the snap plate 222 are integrally formed. When manufacturing the snap part 220, the snap cover 221 and the snap plate 222 are composed of an integral structure, so that they only need to be manufactured once, without secondary or multiple processing, and the structure is more compact.

[0034] like Figure 5 and Figure 7As shown, in one embodiment, the latching block 212 includes a first latching block 2121 and a second latching block 2122. The latching cover 221 includes a first sub-cover 2211, a transition sub-cover 2212, and a second sub-cover 2213 connected in sequence. The transition sub-cover 2212 is connected to the latching plate 222. The first sub-cover 2211 has a first latching groove 2211a, and the second sub-cover 2213 has a second latching groove 2213a. The first latching block 2121 is located in the first latching groove 2211a, and the second latching block 2122 is located in the second latching groove 2213a. In this embodiment, when the first latching block 2121 engages with the first latching groove 2211a, and the second latching block 2122 engages with the second latching groove 2213a, the connection strength between the PIN wire body 100 and the connecting shell 210 is initially enhanced by the latching cover 221, and then the connection strength of the overall structure is further enhanced by the anti-detachment piece 230. In this embodiment, the first latching block 2121 and the second latching block 2122 are disposed on the left and right sides of the connecting housing 210, and the first latching groove 2211a and the second latching groove 2213a are located on the left and right sides of the latching member 220. In another embodiment, both the first latching groove 2211a and the second latching groove 2213a are disposed facing the latching plate 222.

[0035] Furthermore, the first sub-cover 2211, the transition sub-cover 2212, and the second sub-cover 2213 are integrally formed. It can be understood that when manufacturing the snap-on cover 221, the first sub-cover 2211, the transition sub-cover 2212, and the second sub-cover 2213 are assembled as a single integral structure, thus requiring only one fabrication. This results in a more compact structure between the first sub-cover 2211, the transition sub-cover 2212, and the second sub-cover 2213, occupying less space.

[0036] In one embodiment, the anti-detachment tab 230 is a silicone sheet. In this embodiment, using a silicone sheet increases the friction between the silicone sheet and the snap-fit ​​plate 222, as well as the friction between the silicone sheet and the PIN wire body 100, preventing slippage of the silicone sheet that could reduce connection strength. In other embodiments, the anti-detachment tab 230 may also be a rubber sheet.

[0037] In one embodiment, the top of the snap fastener 220 is on the same horizontal plane as the top of the connecting housing 210. In this embodiment, after assembling the connecting line, the snap fastener 220 seals the opening of the mounting channel 2101. At this time, the top of the snap fastener 220 and the top of the connecting housing 210 are on the same horizontal plane, thereby making the structure more flat at the top. Furthermore, the transition cover 2212 is disposed on the same horizontal plane as the opening of the mounting channel 2101 adjacent to the middle portion 110.

[0038] In one embodiment, the thickness of the anti-detachment sheet 230 is 0.6mm-0.8mm. In this embodiment, the thickness of the anti-detachment sheet 230 is 0.6mm.

[0039] In one embodiment, the length of the contact portion 120 is 15mm-20mm. In this embodiment, the length of the contact portion 120 is 18mm.

[0040] In one embodiment, the length of the gold finger is 3.8mm-4.2mm. In this embodiment, the length of the gold finger is 4mm to ensure that when the reinforced PIN connector 10 is connected to the motherboard / driver board, the gold finger makes full contact with the pins of the motherboard / driver board, so that the connector can be electrically connected normally.

[0041] This disclosure also provides an energy storage device, including the reinforced PIN connector 10 of any of the above embodiments.

[0042] Compared with the prior art, this disclosure has at least the following advantages:

[0043] The aforementioned reinforced PIN connector 10 has a strong connection structure 200. Specifically, an anti-detachment tab 230 is added to the assembled PIN connector. Since the end of the PIN wire body 100 and the snap plate 222 are both located within the installation channel 2101, the anti-detachment tab 230 fills the gap between the end of the PIN wire body 100 and the snap plate 222. This allows the structure formed between the end of the PIN wire body 100, the anti-detachment tab 230, and the snap plate 222 to over-fill the installation channel 2101, thereby enhancing the connection strength between the PIN wire body 100 and the connection structure 200. This makes it less likely for the PIN wire body 100 to detach, ensuring the stability of the wiring within the equipment and thus guaranteeing the overall performance and reliability of the equipment.

[0044] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
