Problems solved by technology

[0005] The present invention provides a connector with a locking device to solve the problem that at the moment when the existing connector is disconnected, because the high-voltage connector itself does not have the breaking capacity, the voltage of the entire circuit loads both ends of the breakpoint, which will cause the voltage to break through the air. Drawing an arc between two devices presents a safety hazard that could cause personal injury

Embodiment Construction

[0063] In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0064] The embodiment of the present invention discloses a connector with a locking device. The device is applied to the field of electric vehicles. By using low-voltage signals, all branches connected to the high-voltage busbar on the electric vehicle are checked, including the entire battery system, wires, connectors, The electrical connection integrity (continuity) of system circuits such as DCDC, motor controller, high-voltage box and protective cover, when it is identified that the circuit is abnormally disconnected, the high-voltage power is disconnected in time.

[0065] like Figure 2a and Figure 2b As shown, this embodiment discloses a connector with a locking device, including: a first connecting device 10, a second ...

Abstract

The invention discloses a connector with a locking device, comprising a first connecting device, a second connecting device, a first locking device and a second locking device; the second connecting device is used to fix and protect the interior of the second connecting device The power supply terminal and the signal terminal of the first connection device are adapted to match the second connection device; the upper surface of the first connection device is provided with a first connection structure, and the first connection structure is engaged with the first locking device; The second connecting structure is detachably connected with the first locking device, the upper surface of the second connecting device is provided with a second connecting structure, and the second connecting structure is engaged with the second locking device. The high-voltage interlock structure of the connector can realize the function that the low-voltage monitoring circuit in the connector is disconnected before the high-voltage circuit and maintains a certain advance.

Description

technical field [0001] The present invention relates to the field of connectors, in particular to a connector with a locking device. Background technique [0002] Connectors are electrical and electronic transmission and connection components between circuits, components or systems, which make the signal current flow stably and reliably, and are convenient for combination and maintenance. [0003] like Figure 1a and Figure 1b Shown is a schematic structural diagram of an existing connector, including a male plastic box 1, a mother plastic box 2 and a connector locking device 3 (Connector Position Assurance, CPA), wherein the male plastic box 1 is used to fix the power male terminals and Signal female terminal, the mother plastic box 2 is used to fix the power female terminal and the signal male terminal. In order to ensure the stable connection of the two types of male and female terminals, in the existing connector installation process, the connector locking device 3 is ...
