Description

Technical Field

[0001] The utility model relates to the technical field of electric energy transmission devices, and more specifically, to an electric energy transmission component. Background Art

[0002] In a connector for transmitting high-voltage and large-current electric energy, an electric energy transmission method is usually adopted in which two sheet-type male terminals are conductively connected through an intermediate female terminal. Among them, the female terminal includes a housing and a reed inside the housing. The reed has a plurality of reed claws corresponding to the insertion interfaces of the housing. When the male terminal is inserted into the insertion interface, the reed claws are in conductive contact with the end face of the male terminal.

[0003] The current electric energy transmission component adopts an over-stress state design, that is, under the condition of reducing the size and quantity of the reed claws, the stress received by the reed claws is increased as much as possible. After the male terminal is inserted into the female terminal, the reed claws are in an over-stress state. Although this design ensures that the reed claws and the male terminal have sufficient contact force and contact area, achieving the effect of high current carrying capacity with small size, the insertion and extraction life of the reed claws is short, and repeated insertion and extraction will cause the reed claws to undergo non-recoverable deformation earlier. Summary of the Utility Model

[0005] An electric energy transmission component provided by the utility model includes: a housing, at least two insertion cavities distributed in an array are arranged in the housing, a first opening and a second opening at a predetermined angle are arranged on the periphery of each insertion cavity, and both the first opening and the second opening are communicated with the insertion cavity; a transfer reed, one transfer reed is arranged in each insertion cavity; a first terminal and a second terminal, at least two independent insertion parts are formed by extending one end of the first terminal and the second terminal, at least two insertion parts of the first terminal are respectively inserted into the corresponding insertion cavities through at least two first openings and are conductively connected to the transfer reed, and at least two insertion parts of the second terminal are respectively inserted into the corresponding insertion cavities through at least two second openings and are conductively connected to the transfer reed, so as to realize the conductive connection between the first terminal and the second terminal.

[0006] Optionally, the number of the insertion cavities is the same as the number of the insertion parts arranged at one end of the first terminal and the second terminal, and the insertion cavities are arranged in one-to-one correspondence with the insertion parts arranged at one end of the first terminal and the second terminal.

[0007] Optionally, both the first terminal and the second terminal are stacked by at least two sheet-type male terminal units, and one end of at least two male terminal units is offset from each other to form independent insertion parts.

[0032] The following description of at least one exemplary embodiment is actually merely illustrative and in no way limits the present invention or its application or use.

[0033] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification.

[0034] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0035] As Figures 1-7 shown, an embodiment of the present utility model discloses an electric energy transmission component, including:

[0036] A housing 2, in which there are at least two plugging cavities 24 distributed in an array. Around each plugging cavity 24, there are a first opening 21 and a second opening 22 at a predetermined angle, and both the first opening 21 and the second opening 22 are communicated with the plugging cavity 24;

[0037] A transfer reed 4, and one transfer reed 4 is arranged in each plugging cavity 24;

[0038] A first terminal 1 and a second terminal 3. At one end of the first terminal 1 and the second terminal 3, at least two independent plugging portions are formed by extension. At least two plugging portions of the first terminal 1 are respectively plugged into the corresponding plugging cavities 24 through at least two first openings 21 and are electrically connected to the transfer reed 4, and at least two plugging portions of the second terminal 3 are respectively plugged into the corresponding plugging cavities 24 through at least two second openings 22 and are electrically connected to the transfer reed 4, so as to realize the electrical connection between the first terminal 1 and the second terminal 3.

[0039] Specifically in this embodiment, as Figures 1-7 shown, only as an example, in this embodiment, the housing 2 has two plugging cavities 24. The plugging portions of the first terminal 1, i.e., the first plugging portions 11, also have two, and the plugging portions of the second terminal 3, i.e., the second plugging portions 31, also have two. The two first plugging portions 11 are respectively plugged into the corresponding plugging cavities 24 through the two first openings 21 and are electrically connected to the corresponding transfer reed 4, and the two second plugging portions 31 are respectively plugged into the corresponding plugging cavities 24 through the two second openings 22 and are electrically connected to the corresponding transfer reed 4. That is, in this embodiment, the number of plugging cavities 24 is the same as the number of plugging portions provided at one end of the first terminal 1 and the second terminal 3, and the plugging cavities 24 are arranged in one-to-one correspondence with the plugging portions provided at one end of the first terminal 1 and the second terminal 3.

[0040] By increasing the number of parallel pluggings and electrical connections in a set of electric energy transmission components, this solution provides more contact points, and the plugging stress of the reed claws 41 of the transfer reed 4 can be reduced. Thus, on the premise of meeting the high-current-carrying function, the plugging and unplugging life can be improved based on a lower plugging stress.

[0041] In other embodiments, the number of insertion cavities may also be more than the number of insertion portions formed at one ends of the first terminal and the second terminal, and the number of insertion portions formed at one ends of the first terminal and the second terminal may also be inconsistent. Thus, in actual insertion, there may be vacancies in the first opening or the second opening to meet the needs of, for example, multi-channel conductive connection. For example, the number of insertion cavities is five, and both the corresponding first opening and the second opening have five. However, the number of insertion portions of the first terminal is two, and the number of insertion portions of the second terminal is three. During assembly, the insertion portions of the first terminal are correspondingly inserted into two first openings, and the insertion portions of the second terminal are correspondingly inserted into three second openings. The remaining first openings and second openings can be used as spare ports or for other terminals to be inserted.

[0042] Further, for ease of manufacturing, both the first terminal 1 and the second terminal 3 are stacked by at least two sheet-like male terminal units, and one ends of at least two male terminal units are offset from each other to form independent insertion portions. As Figure 3 、 4 shown, in this embodiment, the first terminal 1 is stacked by two sheet-like first male terminal units 12, and one ends of the two first male terminal units 12 are offset from each other to form independent first insertion portions 11. The second terminal 3 is stacked by two sheet-like second male terminal units 32, and one ends of the two second male terminal units 32 are offset from each other to form independent second insertion portions 31. Among them, the first terminal 1 extends linearly as a whole, and the second terminal 3 is bent at a right angle as a whole to adapt to the actual conductive connection scenario and the needs of structural design.

[0043] Further, for ease of connection with the corresponding cables, as Figure 3 、 4 shown, in this embodiment, the other ends of the two male terminal units are stacked to form a connection portion, and one side surface of the connection portion constitutes a connection surface for connecting the corresponding cables by, for example, welding, that is, the first connection portion 13 and the first connection surface 14 of the first terminal 1, and the second connection portion 33 and the second connection surface 34 of the second terminal 3.

[0044] Further, for obtaining good conductor application performance, in this embodiment, the male terminal units, namely the first male terminal unit 12 and the second male terminal unit 32, are both made of copper / copper alloy such as red copper, and the other ends of adjacent two male terminal units are fixedly connected to each other by ultrasonic welding, that is, the other ends of adjacent two first male terminal units 12 and the other ends of adjacent two second male terminal units 32 are both fixedly connected to each other by ultrasonic welding.

[0045] Further, for ease of manufacturing, the housing 2 is stacked by at least two female terminal units 23, as Figure 5 、 7As shown, specifically in this embodiment, the housing 2 is formed by stacking two female terminal units 23. Each female terminal unit 23 is provided with a plugging cavity 24. A transfer reed 4 is arranged in the plugging cavity 24. A first opening 21 and a second opening 22 at a predetermined angle are arranged on the outer periphery of the plugging cavity 24, and both the first opening 21 and the second opening 22 are communicated with the plugging cavity 24. In addition, for the convenience of installation and fixation, a plurality of fixing fins 231 are further arranged on the outer side of the female terminal unit 23.

[0046] Further, in order to avoid relative displacement between the female terminal units 23, facilitate transportation, disassembly and assembly, two adjacent female terminal units 23 are fixedly connected to form an integral structure, so that the entire housing 2 actually forms an integral structure.

[0047] Further, in order to ensure the structural strength of the female terminal unit 23 and meet the fixed strength requirements, in this embodiment, the female terminal unit 23 is made of iron / iron alloy such as steel, and two adjacent female terminal units 23 are fixedly connected to each other by laser welding.

[0048] In other embodiments, other fixing methods can also be used to connect two adjacent female terminal units, such as bonding, riveting, etc.; for the housing, it can also be formed by cutting and processing a whole piece of material, and corresponding numbers of plugging cavities, first openings and second openings are processed.

[0049] Further, in order to make the conductive connection effect between the transfer reed 4 and the corresponding plugging part better and make full use of the conductive contact points, as Figures 5-7 shown, in this embodiment, the transfer reed 4 is fixedly arranged on the inner wall of the plugging cavity 24 by means such as riveting, and a plurality of reed claws 41 are arranged at both ends. The reed claws 41 at each end are evenly distributed on the inner periphery of the corresponding first opening 21 or second opening 22.

[0050] Further, in this embodiment, the predetermined angle between the above-mentioned first opening 21 and the second opening 22 is 180°, that is, the first opening 21 and the second opening 22 are located on the same plugging straight line, so that the first terminal 1 and the second terminal 3 are inserted relatively on the same plugging straight line.

[0051] In other embodiments, considering the plugging direction under the actual layout of the first terminal and the second terminal, the predetermined angle between the first opening and the second opening can be 90° - 180°, such as 90°, 135°.

[0052] During specific use, the first terminal 1 can be fixed inside the socket connector, and the second terminal 3 can be fixed inside the plug connector. Then, the housing 2 already equipped with the transfer reed 4 is inserted into the plug connector, and the second opening 22 is correspondingly inserted into the second insertion portion 31 of the second terminal 3. When the plug connector is inserted into the socket connector, the first insertion portion 11 of the first terminal 1 is correspondingly inserted into the first opening 21, achieving the electrical connection between the first terminal 1 and the second terminal 3.

[0053] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration purposes and not for limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
