Embodiment Construction

[0014] Such as figure 2 As shown, the electrical connector of this embodiment includes a housing 14, a connector terminal 12 is fixed on the bottom surface inside the housing 14, a wire 13 penetrates from the side wall of the housing, and the wire terminal 11 at the end is placed on On the upper end surface of the connector terminal 12, the wire terminal 11 and the connector terminal are connected through the mounting hole 110 of the wire terminal and the mounting hole 120 of the connector terminal through screws or bolts (not shown in the figure). 12 are fixedly connected.

[0015] The electrical connector is also provided with a micro switch, and the main body part 142 of the micro switch is fixedly assembled on the outside of the housing 14 through the mounting bracket 141, such as image 3 shown. The main part of the micro switch includes the actuator part, the snap action mechanism part, the contact part and the terminal part; the actuator part is used to transmit the ...

Abstract

The invention relates to an electric connector, which comprises a shell, wherein a wire connecting terminal, a connector connecting terminal and a connecting bolt are arranged in the shell, and the connecting bolt is fixedly connected with the wire connecting terminal and the connector connecting terminal; the connector connecting terminal is provided with an upper end face used for being in contact with the wire connecting terminal; and a through hole is formed in the upper end face, a driving rod of a microswitch is arranged in the through hole, and the upper end of the driving rod protrudesout of the upper end face. According to the invention, the microswitch is arranged, and the state of the microswitch is associated with the state of loose connection, so that information of the looseconnection can be obtained in time so as to give an alarm in time and avoid the occurrence of risks and dangers.

Description

[0001] The invention relates to an electrical connector. Background technique [0002] Existing high-voltage connectors for electric vehicles can be divided into two types: plug-in type and screw-in type. The former is easy to operate, but it is difficult to guarantee the reliability of the whole life cycle under automotive conditions, and the cost is high; the cost of the latter is low, but if If the operator does not tighten the bolts, or the bolts are not tightened but the torque is normal due to abnormal thread fit, the contact area will become smaller, the contact resistance will increase, and there will be a risk of ablation due to heat generation. Such as figure 1 As shown, the wire terminal 1 and the connector terminal 2 are screwed and fixed by bolts 3 . However, when the car is not compressed or when the car is running in a bumpy situation, such figure 1 The shown connection between the wire terminal 1 and the connector terminal 2 is loose, resulting in various ris...
