请参图1及图2所示,插套1包括管状插套本体10,插套本体10一端设有鼓簧11,另一端设有第一线缆连接部12。鼓簧11用于与插针2插接,其包括若干个弧形弹片,弧形弹片的向插套本体10内突出设置。如此设置,方便插针2与插套1的插拔。优选的,鼓簧11为插套本体10端部冲压形成,如此设置,降低插套1与插针2的接触电阻,减少功率损耗。第一线缆连接部12用于与外部导线的接线端子相连。第一线缆连接部12 的具体结构为现有结构,在此不作赘述。Referring to FIGS. 1 and 2 , the socket 1 includes a tubular socket body 10 . One end of the socket body 10 is provided with a drum spring 11 , and the other end is provided with a first cable connection portion 12 . The drum spring 11 is used for plugging with the pin 2 , and includes a plurality of arc-shaped elastic pieces, and the arc-shaped elastic pieces are arranged to protrude into the socket body 10 . This arrangement facilitates the insertion and removal of the pin 2 and the socket 1 . Preferably, the drum spring 11 is formed by stamping the end of the socket body 10 , and this arrangement reduces the contact resistance between the socket 1 and the pin 2 and reduces power loss. The first cable connection part 12 is used for connecting with the connection terminal of the external wire. The specific structure of the first cable connection portion 12 is the existing structure, which is not repeated here.

In the present invention, the elastic guide portion 14 is formed by punching the insert sleeve body 10, which is convenient for processing. In other embodiments, the elastic guide portion 14 and the socket body 10 can be set as separate structures, and the elastic guide portion 14 is sleeved on the outside of the socket body 10, which can also achieve the purpose of automatic guidance.

请参图1及图2所示,插针2包括插针本体20,其一端设有与插套1 接触的插接部21,另一端为第二线缆连接部22,插针本体20周向上还设有第二限位部23,其结构与第一限位部13结构相同,在此不作赘述。在其他实施方式中,弹性导向部14也可设置于插针2外侧,以实现插套1 与插针2配合插接时的自动导向的目的。Referring to FIG. 1 and FIG. 2 , the pin 2 includes a pin body 20 , one end of which is provided with a plug portion 21 contacting with the socket 1 , and the other end is a second cable connection portion 22 . The pin body 20 surrounds A second limiting portion 23 is also provided upward, and its structure is the same as that of the first limiting portion 13 , which will not be repeated here. In other embodiments, the elastic guide portion 14 may also be disposed on the outer side of the pin 2 to achieve the purpose of automatic guidance when the socket 1 and the pin 2 are mated and plugged.

本实用新型中,插套1及插针2均优选为一体成型结构,如此设置,降低了插套1与插针2的电阻,减少功率损耗。In the present invention, the socket 1 and the pin 2 are preferably integrally formed structures, and such arrangement reduces the resistance of the socket 1 and the pin 2 and reduces power loss.

综上所述,本实用新型通过在插套本体的周向上设置弹性导向部,一方面可以降低装配通道的设计精度,易于插套装配,另一方面,当插套与插针同轴度较低时,使得插套能随插针灵活摆动,自动导正其轴线方向,使其与插针的轴线方向一致,插接方便,提升插套与插针的使用寿命。另外,本实用新型通过将鼓簧一体设置在本体的一端,降低了插套与插针的接触电阻,减少功率损耗,进一步提高光伏电池的发电效率。To sum up, by arranging an elastic guide portion in the circumferential direction of the socket body in the present invention, on the one hand, the design accuracy of the assembly channel can be reduced, and the socket assembly is easy; When it is low, the socket can swing flexibly with the pin, automatically guide its axis direction to make it consistent with the axis direction of the pin, which is convenient for insertion and improves the service life of the socket and the pin.
