Problems solved by technology

[0004] It has the following problems: When installing the client terminals, the locking bolts need to be unscrewed
Since the signal transmission between the shunt and the internal PCBA main board of the product is carried out through a 1.0 square wire, the wire is easy to be torn after the shunt swings, which affects the normal use of the product

Abstract

The invention discloses a device with a secondary locking function for fixing a terminal, a shunt and a product housing. The device comprises a non-standard nut, a non-standard bolt and a common bolt.The non-standard nut is fixedly connected with the housing, a first threaded hole is axially arranged at the non-standard nut along the axial direction, the inner wall of the first threaded hole is provided with a first internal thread, the non-standard bolt is provided with a first external thread matched with the first internal thread, the non-standard bolt is connected with the first threadedhole for fixing the shunt, the non-standard bolt is provided with a cut-through through hole in the axial direction, the first threaded hole is provided with a second threaded hole in the axial direction, the hole diameter of the second threaded hole is smaller than that of the first threaded hole, the inner wall of the second threaded hole is provided with a second internal thread, the common bolt is provided with a second external thread matched with the second internal thread, the common bolt penetrates the through hole to be connected with the second threaded hole to fix the terminal and the product housing. The device with a secondary locking function achieves secondary locking to avoid that the shunt is forced to swing to cause breaking of the wire after the bolt is loosened.

Description

technical field [0001] The invention relates to the technical field of fastening equipment, in particular to a device with a secondary locking function. Background technique [0002] The current and voltage monitoring module is widely used in the field of new energy vehicles. It can collect and display the current and voltage values ​​of the bus in real time, calculate the SOC value of the battery, and judge whether the relay is stuck. [0003] There is an important functional part in the current and voltage monitoring module, namely the shunt. like figure 1 As shown, it is a schematic diagram of the installation of the existing shunt. In the figure, 11 is the housing of the current and voltage monitoring module, 12 is the shunt, 13 is the common bolt, and 14 is the connection terminal. The housing 11 and the shunt 12 are respectively equipped with The threaded holes and through holes matched with the ordinary bolts 13 , the ordinary bolts 13 pass through the shunt 12 and ...
