Furthermore, an annular flange is formed on the inner wall at the other end of the through hole, and the contact head pushes the cable against the annular flange.

Further, the collision head is a cone.

Further, the male end assembly also includes a main body rubber shell, a dustproof cap and a fastening wire clamp, and a snap spring is formed on the contact terminal, and the contact terminal is accommodated in the main body plastic shell through the snap spring, and the fastening wire The clamp and the dustproof cap are respectively sealed and connected to the two ends of the main rubber shell, and the fastening clamp is set on the cable.

Further, a silicone color ring is formed on the main rubber shell, and a matching color ring corresponding to the color of the silicone color ring is formed on the female end assembly.

After adopting the above structure, the utility model relates to an industrial quick connector, which is threadedly connected by the external thread part of the contact terminal and the internal thread part of the fastening terminal, so that the contact terminal and the fastening terminal can be connected together , at the same time, because the contact head of the contact terminal can be electrically connected with the cable inserted from the other end of the fastening terminal, so that the cable can be directly electrically connected with the plug connector of the contact terminal, thereby achieving the advantage of good connection stability; at the same time further By providing an annular flange in the through hole of the center passage, the force of the threaded connection is utilized so that the contact head can push the cable against the annular flange, thereby achieving a more stable connection effect.

Detailed ways

In order to further explain the technical solution of the utility model, the utility model is described in detail through specific examples below.

As shown in Figures 1 to 5, the utility model relates to an industrial quick connector, which includes a male end assembly 1 and a female end assembly that can be quickly plugged and connected, and the female end assembly is fixedly embedded in the power supply vehicle. The male end assembly 1 is also connected to the cable 2 .

The main improvement of the utility model is that: the male end component 1 includes a contact terminal 11 and a fastening terminal 12, and one end of the contact terminal 11 is formed with a plug joint 111, and the plug joint 111 can be plugged with the female end component, and the contact The other end of the terminal 11 is formed with an external thread portion 112 and a contact head 113, the external thread portion 112 is located between the plug joint 111 and the contact head 113; the fastening terminal 12 has a through hole 121, and the through hole 121 One end is formed with an internal threaded portion 122 that can be threadedly connected with the external threaded portion 112 of the contact terminal 11 , and the other end is used for inserting the cable 2 and electrically connecting the cable 2 with the contact head 113 . Preferably, in order to allow the contact head 113 to fully contact the cable 2, an annular flange 123 is formed on the inner wall at the other end of the through hole 121, and the contact head 113 pushes the cable 2 against the ring flange 123 . In this embodiment, the resisting head 113 is a cone.
