a terminal mounting plate clamped between the boss of the housing and the plug;
the wiring terminal is arranged on the terminal mounting plate, the front end of the wiring terminal extends into the terminal hole of the plug, the rear end of the wiring terminal is connected with a wire, and the other end of the wire extends out of the rear end of the wire inlet cavity of the shell;
and the front end of the screw penetrates through the screw mounting hole of the shell and is connected with nuts arranged in the nut positioning grooves at the two ends of the plug.
The connector, its characterized in that: the rear end of the shell is provided with a raised wire protecting part, and the wire extends out of the wire protecting part.
The connector, its characterized in that: both sides of the nut are flush with the plug.
The connector, its characterized in that: the front end edge of the shell is integrally formed with a flange.
The connector, its characterized in that: and a gasket is arranged on the screw rod.
The connector, its characterized in that: the front end of the wiring terminal is an insertion column, and the rear end of the wiring terminal is an annular positioning part.
The connector, its characterized in that: and sealant is filled in the wire inlet cavity of the shell.
The utility model discloses a connector advantage as follows: set up the detachable plug at integrative injection moulding casing front end, install binding post on the terminal block back centre gripping in the casing with between the plug, adopt this kind of mode installation to compromise the advantage of two traditional modes, not only waterproof performance is good, and the terminal can be replaced, production is also comparatively simple in addition.
The present invention will be further explained with reference to the drawings.

Detailed Description
Referring to fig. 1-6, the connector of the present invention comprises: the plug comprises a shell 1, a plug 2, a terminal mounting plate 3, a wiring terminal 4 and a screw 5. The improved cable-feeding device is characterized in that the shell body is integrally formed by injection molding, screw mounting holes 6 are formed in two ends of the shell body 1, a cable-feeding cavity 7 is formed in the middle of the shell body 1, and a boss 8 is arranged on the cable-feeding cavity 7. The plug 2 is inserted on the boss 8 of the shell 1, the two ends of the plug 2 are provided with nut positioning grooves 9, nuts 12 are installed through the nut positioning grooves 9, and the nuts 12 are ideally hexagonal nuts. The nut positioning groove 9 is aligned with the nut 12 through an included angle formed by the inner side of the nut positioning groove and the hexagon nut, and the nut is prevented from rotating. A set of terminal holes 10 is provided in the middle of the header 2. The terminal mounting plate 3 is sandwiched between the boss 8 of the housing 1 and the plug 2. The wiring terminal 4 is inserted into the terminal mounting plate 3. The front end of the connecting terminal 4 extends into a terminal hole 10 of the plug 2, and the extending part is used for electrically contacting the connecting terminal in the connector socket. The rear end of the wiring terminal 4 is connected with a wire 11, and the wire 11 is fixedly welded with the wiring terminal 4. The other end of the lead 11 extends out of the rear end of the wire inlet cavity 7 of the shell 1.
