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 comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

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

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

Abstract

The invention discloses a connector with a locking device. The connector comprises a first connecting device, a second connecting device, a first locking device and a second locking device, wherein the second connecting device is used for fixing and protecting a power supply terminal and a signal terminal in the second connecting device, and the first connecting device is matched with the second connecting device; a first connecting structure is arranged on the upper surface of the first connecting device, and the first connecting structure is clamped with the first locking device; the secondconnecting structure is detachably connected with the first locking device, a second connecting structure is arranged on the upper surface of the second connecting device, and the second connecting structure is clamped with the second locking device. According to the high-voltage interlocking structure of the connector, a low-voltage monitoring loop in the connector can be disconnected earlier than a high-voltage loop, and a function of keeping a certain advance can be realized.

Description

technical field [0001] The 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, making signal currents flow stably and reliably, and facilitating assembly and maintenance. [0003] Such as Figure 1a and Figure 1b Shown is a schematic structural diagram of an existing connector, including a male plastic box 1, a female 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 The signal female terminal, the female rubber 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 first assembled i...
