Description

Technical Field

[0001] This utility model relates to a connector, specifically a new energy connector with signal pins. Background Technology

[0002] New energy connectors are electrical interface devices used in new energy vehicles, energy storage systems and other fields. Their core function is to realize power transmission and signal exchange under high voltage and high current. They have technical characteristics such as high protection, high temperature resistance and electromagnetic compatibility. They are typically used to connect battery packs and motor controllers in electric vehicles.

[0003] Existing new energy connectors have complex structures and unreasonable designs, typically featuring only one connection terminal. The two ends of this terminal are plugged into corresponding power structures, which apply pressure to the connector at both ends, resulting in poor stability, easy wear, and shortened lifespan. Furthermore, new energy connectors usually do not have direct signal pins, preventing the direct transmission of control signals and communication data, leading to poor stability during charging. Therefore, the inventors have improved the structure of the new energy connector. Utility Model Content

[0004] The purpose of this utility model is to provide a new energy connector with a signal pin. This new energy connector with a signal pin has the advantages of simple structure, reasonable design, higher connection stability, less wear, and longer life. In use, the signal pin is inserted into the pin sleeve to complete the coupling connection. The signal pin can transmit control signals and communication data, ensuring the charging process is safe, efficient and stable, thus solving the problems mentioned in the above technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a new energy connector with a signal pin, comprising a first connecting terminal and a second connecting terminal connected end to end. The first connecting terminal includes a first housing, inside which a first contact and a signal pin located on one side of the first contact are fixed. The signal pin includes a support foot and a needle head fixed on the support foot, the needle head being cylindrical. The second connecting terminal includes a second housing, inside which a second contact and a needle sleeve located on one side of the second contact are fixed. The first housing and the second housing have identical structures. The needle sleeve includes a connecting rod and a sleeve fixed on the connecting rod. A receiving groove is provided at the end of the sleeve away from the connecting rod, and a limiting member is provided in the receiving groove. The end of the needle head away from the support foot enters the receiving groove and fits into the limiting member, allowing the signal pin and the needle sleeve to connect perfectly. The limiting member fixes the needle head in the receiving groove, ensuring the stability of the signal pin and the needle sleeve connection and preventing the signal pin from falling off during long-term use, thus achieving better safety.

[0006] Preferably, there are two first contact members and two second contact members, the two first contact members are arranged in parallel, and each first contact member is connected end to end with one of the second contact members.

[0007] Preferably, a first protective sleeve is provided at the end of the support foot near the needle. The first protective sleeve is in contact with the needle. When the needle is subjected to pressure, some of the pressure will be transmitted to the first protective sleeve. Therefore, the first protective sleeve can play a certain role in reducing pressure on the needle and provide a certain protection for the support foot and the needle.

[0008] Preferably, the limiting member is a hollow cavity structure with openings at both ends, and the limiting member is in contact with the inner wall of the receiving groove, so that the limiting member can be fixed in the receiving groove and cannot move.

[0009] Preferably, the limiting component includes a hollowed-out sleeve, with a recessed portion provided at the center of the hollowed-out sleeve.

[0010] Preferably, the diameter of the hollowed-out sleeve is larger than the diameter of the recess. Multiple hollowed-out grooves are provided through the circumference of the recess. The structural strength of the limiting member can be reduced by the multiple hollowed-out grooves. After the needle is inserted into the cavity of the limiting member, a certain friction and pressure are generated between the needle and the limiting member. The limiting member will not wear the needle and can also limit the needle.

[0011] Preferably, a second protective sleeve is provided at one end of the connecting rod near the sleeve. The second protective sleeve is in contact with the sleeve. The structure of the second protective sleeve is the same as that of the first protective sleeve, and the function of the second protective sleeve is the same as that of the first protective sleeve. However, the second protective sleeve is to reduce the pressure on the sleeve when the needle is inserted into the sleeve, and to reduce the pressure on the sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a new energy connector with a signal pin. The new energy connector with a signal pin includes a first connecting terminal and a second connecting terminal connected end to end. The overall structure is simple and reasonably designed. The first connecting terminal includes a first housing, inside which a first contact and a signal pin located on one side of the first contact are fixed. The second connecting terminal includes a second housing, inside which a second contact and a pin sleeve located on one side of the second contact are fixed. By setting two connecting terminals that are plugged into each other to achieve the coupling connection function, the ends of the two connecting terminals that are far apart from each other are respectively connected to the external power structure. Therefore, the pressure generated by the power structure at both ends is more dispersed, and the connection stability is higher. It is not easy to wear and has a longer service life. In use, the coupling connection is completed by inserting the signal pin into the pin sleeve. The signal pin can transmit control signals and communication data, ensuring the safety, efficiency and stability of the charging process. It is suitable for widespread use.

[0014] 2. The signal needle in this utility model includes a support foot and a needle head fixed on the support foot. The needle head is cylindrical. The needle sleeve includes a connecting rod and a sleeve fixed on the connecting rod. A receiving groove is provided at the end of the sleeve away from the connecting rod. A limiting member is provided in the receiving groove. The end of the needle head away from the support foot enters the receiving groove and fits into the limiting member, so that the signal needle and the needle sleeve can be perfectly connected. The limiting member fixes the needle head in the receiving groove, which can ensure the stability of the signal needle and the needle sleeve after connection. When the needle head is inserted into the receiving groove, it enters the interior of the recess. Under the action of the recess, the hollow sleeve generates a certain friction and pressure on the needle head, so that the signal needle structure will not fall off the needle sleeve, ensuring the tightness of the connection between the two. It can also prevent the signal needle from falling off during long-term use, thus ensuring safety and stability. Attached Figure Description

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0024] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0025] Please see Figure 1One embodiment of this utility model is a new energy connector with signal pins, which includes a first connecting terminal 1 and a second connecting terminal 2 connected end to end.

[0026] Please see Figure 2 The first connecting terminal 1 includes a first housing 11, inside which a first contact 12 and a signal pin 13 located on one side of the first contact 12 are fixed. The second connecting terminal 2 includes a second housing 21, inside which a second contact 22 and a pin sleeve 23 located on one side of the second contact 22 are fixed. Two first contacts 12 and two second contacts 22 are provided, arranged parallel to each other, with each first contact 12 connected end-to-end with one of the second contacts 22. The coupling connection is achieved by inserting the signal pin 13 into the pin sleeve 23. The signal pin 13 can transmit control signals and communication data, ensuring the safety, efficiency, and stability of the charging process. The coupling connection function is achieved by setting two mutually plugged connections. The terminals, with their ends far apart, are connected to external electrical structures. This disperses the pressure generated by the electrical structures at both ends, resulting in higher connection stability, less wear, and a longer lifespan. The first housing 11 and the second housing 21 have identical structures. After rotating the first housing 11 180° along its horizontal central axis, its orientation will be the same as that of the second housing 21. The fixing methods of the first contact 12 and the signal pin 13 inside the first housing 11, and the fixing methods of the second contact 22 and the pin sleeve 23 inside the second housing 21, are existing technologies and will not be described in detail here. Furthermore, in this embodiment, each first contact 12 corresponds to two signal pins 13, and each signal pin 13 corresponds to one pin sleeve 23.

[0027] Please see Figure 3 The signal needle 13 includes a support foot 131 and a needle head 132 fixed on the support foot 131. The needle head 132 is cylindrical. A first protective sleeve 133 is sleeved on one end of the support foot 131 near the needle head 132. The first protective sleeve 133 is in contact with the needle head 132. When the needle head 132 is under pressure, some of the pressure will be transmitted to the first protective sleeve 133. Therefore, the first protective sleeve 133 can play a certain pressure reduction role on the needle head 132 and play a certain protective effect on the support foot 131 and the needle head 132. The needle sleeve 23 includes a connecting rod 231 and a sleeve 232 fixed on the connecting rod 231.

[0028] Please see Figure 4A second protective sleeve 234 is fitted on one end of the connecting rod 231 near the sleeve 232. The second protective sleeve 234 is in contact with the sleeve 232. The structure of the second protective sleeve 234 is the same as that of the first protective sleeve 133, and the function of the second protective sleeve 234 is the same as that of the first protective sleeve 133. However, the second protective sleeve 234 is to reduce the pressure on the sleeve 232 when the needle 132 is inserted into the sleeve 232, and thus reduce the pressure on the sleeve 232.

[0029] Please see Figure 5 A receiving groove 2321 is provided at the end of the sleeve 232 away from the connecting rod 231. A limiting member 233 is provided in the receiving groove 2321. The limiting member 233 is a hollow cavity structure with openings at both ends. The limiting member 233 is in contact with the inner wall of the receiving groove 2321, so that the limiting member 233 can be fixed in the receiving groove 2321 and cannot move. The end of the needle 132 away from the support foot 131 enters the receiving groove 2321 and fits into the limiting member 233, so that the signal needle 13 and the needle sleeve 23 can be perfectly connected. The limiting member 233 fixes the needle 132 in the receiving groove 2321, which can ensure the stability of the signal needle 13 after it is connected to the needle sleeve 23. The signal needle 13 will not fall off during long-term use, thus achieving better safety.

[0030] Please see Figure 6 The limiting member 233 includes a hollowed-out sleeve 2331, with a recess 2332 at its center. The diameter of the hollowed-out sleeve 2331 is larger than the diameter of the recess 2332. Multiple hollowed-out grooves 2333 are provided through the circumference of the recess 2332. The multiple hollowed-out grooves 2333 can reduce the structural strength of the limiting member 233. After the needle 132 is inserted into the cavity of the limiting member 233, it will enter the recess 2332 after being inserted into the receiving groove 2321. Inside, under the action of the recessed part 2332, the hollowed-out sleeve 2331 generates a certain friction and pressure on the needle 132, so that the signal needle 13 will not fall off the needle sleeve 23, ensuring the tightness of the connection between the two, so that the signal needle 13 will not fall off even after long-term use, ensuring safety and stability. In addition, the signal needle 13 and the limiting member 233 generate a certain friction and pressure, and the limiting member 233 will not wear the needle 132, and can also limit the needle 132.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
