Description

Technical Field

[0001] The utility model relates to the technical field of energy storage equipment, in particular to an energy storage equipment and a signal connector thereof. Background Art

[0002] In electronic products, plug-in connectors are often used to achieve current conduction between different modules. Among them, plug-in connectors are generally used for signal low current transmission, high current transmission and radio frequency signal transmission.

[0003] Compared with small current signal connectors, high current transmission terminal structures are large in size, and mold and material costs are high. The reason is that high current connectors generally have two important functions: on the one hand, they need to be able to achieve blind insertion. When blind plugging connectors, the connectors are in a blind area and cannot be visually aligned for assembly; the male and female sockets need to be guided and aligned through an auxiliary guide structure before insertion; therefore, the connector structure needs to be specially strengthened to avoid damage to the connector due to impact during the plug-in process. Therefore, blind plug connectors are often larger in size and have increased material costs due to these auxiliary structures and other factors. On the other hand, the current per PIN of the connector is large, and the size of each PIN of the high current connector is large, which requires that the male and female pins of each PIN be designed to be thick enough (i.e., large in size), which will also lead to a large final size of the high current connector.

[0030] The following is a detailed description of the implementation of the utility model. It should be emphasized that the following description is only exemplary and is not intended to limit the scope and application of the utility model.

[0031] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it can be directly on the other component or indirectly on the other component. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0034] like Figure 1As shown, the preferred embodiment of the utility model discloses a signal connector for energy storage equipment, including a first signal connection unit 10, a second signal connection unit 20 and a protective cover 30, wherein the first signal connection unit 10 includes a first housing 11 and a plurality of first signal pins 12, wherein the plurality of first signal pins 12 are arranged in the first housing 11, and the second signal connection unit 20 includes a second housing 21 and a plurality of second signal pins 22, wherein the plurality of second signal pins 22 are arranged in the second housing 21, and the second housing 21 can be inserted into the first housing 11 from the open end of the first housing 11 so that the first signal pin 12 and the second signal pin 22 are matched and connected with each other; wherein the protective cover 30 is sleeved at the open end of the first housing 11 and covers at least a part of the end at the open end of the first housing 11. By designing a protective cover on the first signal connection unit 10, the weak part of the ordinary signal connector structure is protected, and it is ensured that the weak part is not damaged when blindly plugged and collided, so as to achieve reliable connection. wherein, the first signal pin 12 and the second signal pin 22 can be PIN pins.

[0035] Combination Figure 2 In this embodiment, the protective cover 30 includes an annular base 31, and a first flange 32 is provided at the inner wall of the open end of the annular base 31, and when the protective cover 30 is sleeved on the open end of the first shell 11, the first flange 32 abuts against the open end of the first shell 11. Among them, a chamfer 321 is provided on the inner wall of the first flange 32, and the chamfer 321 plays the role of inclined surface introduction, and the angle is preferably 45°. In other embodiments, a rounded structure can also be provided on the inner wall of the first flange 32. Furthermore, the length of the first flange 32 protruding from the annular base 31 is less than the thickness of the first shell 11 (that is, the protruding position at the port of the protective cover 30 does not block the first shell 11 as a whole in the thickness direction), and a chamfer 111 is provided at the position of the open end of the first shell 11 not covered by the first flange 32, or a rounded structure can also be provided. When the second shell 21 is on the inclined surface of the chamfer 321 , it will be introduced into the first shell 11 , wherein the opening end of the first shell 11 is also provided with a chamfer 111 or a rounded shape, and the second shell 21 finally enters into the first shell 11 to complete the insertion.

[0036] In a further embodiment, the signal connector further comprises a support plate 40, a hole 41 is formed on the support plate 40, a buckle 33 and a second flange 34 are formed on the outer wall of the annular base 31, the buckle 33 is used to snap-fit ​​the annular base 31 to the hole 41, and the size of the second flange 34 is larger than the size of the hole 41, so that when the annular base 31 is snap-fitted to the hole 41, the second flange 34 abuts against the support plate 40. A gap is provided between the side wall of the hole 41 and the outer wall of the annular base 31, such as Figure 2 As shown, the width of the gap is L. By setting the gap, the annular base 31 can have a sliding space between the support plate 40, such as Figure 3 As shown, when the first signal connector 10 and the second signal connector 20 cooperate with each other and there is a position tolerance, the plug-in portion of the first signal connector 10 fitted by the protective cover 30 can automatically adjust its position within the space of the gap width according to the offset of the second signal connector 20, such as Figure 4 As shown, the insertion is completed, and it can be seen that the automatically adjusted gap width is greater than L.

[0037] In a specific embodiment, the first signal connection unit 10 is a male end of the connector, and the second signal connection unit 20 is a female end of the connector. In ordinary signal connectors, the outer shell of the male end of the connector that accommodates the female end of the connector is relatively weak, and is easily bumped and deformed during the plug-in process, and each PIN male pin (first signal pin 12) is independently exposed. When the female end of the connector is not aligned with the male end of the connector, the second outer shell 21 corresponding to the female end of the connector hits the PIN male pin (first signal pin 12), which will cause the PIN male pin (first signal pin 12) to be skewed and deformed, affecting the contact reliability and causing abnormal connection. The female end of the connector is small in size, but the outer shell is strong enough, and each PIN female terminal (second signal pin 22) is protected by an independent plastic opening and will not be damaged during plug-in. Therefore, in this embodiment, in view of the weakness of the first shell 11 corresponding to the male end of the connector, a reinforcement design is introduced, and a protective cover 30 is provided on the first shell 11, so that when the female end of the connector and the male end of the connector are inserted and collided, the first shell 11 corresponding to the male end of the connector is prevented from being collided by the female end of the connector. When the collision occurs, the force is applied to the protective cover 30, and the force on the protective cover 30 is borne by the support plate 40.

[0038] Among them, the first shell 11, the second shell 21, and the support plate 40 can be made of hard plastic materials respectively, and the protective cover 30 is preferably made of soft plastic material, which mainly plays a role of buffering and guiding; the support plate 40 serves as a fastener to increase the strength and prevent the first shell 11 from breaking.

[0039] The first signal connection unit 10 further includes M first current gathering pieces 13, and the second signal connection unit 20 further includes M second current gathering pieces 23. The number of the first signal pins 12 and the number of the second signal pins 22 are both N. The N first signal pins 12 are divided into M groups, and each first current gathering piece 13 is respectively electrically connected to a group of first signal pins 12. Correspondingly, the N second signal pins 22 are divided into M groups, and each second current gathering piece 23 is respectively electrically connected to a group of second signal pins 22. The number of each group of first signal pins 12 and each group of second signal pins 22 is greater than 1, and the number of each group of first signal pins 12 or second signal pins 22 may be different. M and N are integers, and M<N. The groups into which the first signal pins 12 are divided correspond to the groups into which the second signal pins 22 are divided, so that the first signal pins and the second signal pins at the corresponding positions and the same positions can be current-gathered to improve the current carrying capacity of the signal connector. The first current collecting piece 13 is electrically connected to the tail end of the first signal pin 12, and the second current collecting piece 23 is electrically connected to the tail end of the second signal pin 22. By combining multiple signal pins to collect current, the current carrying capacity of the common signal connector is improved.

[0040] The signal pins of ordinary signal connectors are small in size and have poor current carrying capacity, generally around 3A at most. In this embodiment, the signal pins are divided into multiple groups, and the signal pins of each group are current-concentrated through current-concentrating sheets to achieve excessive current capacity. Figure 5 As shown, in a specific embodiment, for example, the first signal connection unit 10 includes 20 first signal needles 12, and the current carrying capacity of each first signal needle 12 is 3A. The 20 first signal needles 12 are divided into three groups, the first group is 9 first signal needles 12, the second group is 5 first signal needles 12, and the third group is 6 first signal needles 12. Then, the three first current gathering pieces 13 are respectively connected to the tails of the three groups of first signal needles 12, thereby achieving current carrying capacities of 27A, 15A, and 18A, respectively. Correspondingly, the 20 second signal needles 22 in the second signal connection unit 20 are respectively divided into three groups (respectively 9 second signal needles 22, 5 second signal needles 22, and 6 second signal needles 22), and the three second current gathering pieces (not shown in the figure) are respectively connected to the tails of the three groups of second signal needles 22. As shown in FIG. Figure 6 and Figure 7 As shown, in this embodiment, a current gathering piece is designed at the bottom of the signal connector, and the current gathering piece connects the signal pin (signal pin) to the current gathering piece, and then the current gathering piece is welded on the PCB board 50 to achieve large current conduction. The number of different signal pins gathered can achieve different current requirements. In actual application, it can be designed according to actual conditions.

[0041] The signal connector for energy storage equipment provided by the preferred embodiment of the utility model introduces a protection design for plug-in collision. A protective cover is provided on one of the outer shells of the signal connector, which can easily allow the other outer shell to be easily inserted into the outer shell, thereby upgrading an ordinary signal connector (low cost) into a high-function signal connector (high cost). It is highly practical and can upgrade the function of any signal connector on the market. In addition, ordinary signal connectors are low in cost, and there is no need to develop and design signal connector molds, saving material costs and development costs. Furthermore, by using a current gathering sheet to gather currents for multiple signal pins, the current carrying capacity can be significantly improved. Through the above-mentioned improvements, the utility model can directly use an ordinary low-current signal connector, and can directly realize high-current signal connection without the need to develop and design a signal connection mold.
