Abstract

Disclosed is a plug base body used for an electric connector. A jack matching with a socket base body is arranged on the plug base body, and mounting holes are arranged at two sides of the jack. The plug base body is characterized in that the head faces of the mounting holes are horizontal with the head face of the jack; and when the plug base body is matched with the socket base body, the head faces of the mounting holes of the plug base body tightly rest against the head faces of the corresponding mounting holes of the socket base body. The plug base body enables the down-pressing contact planes at the mounting holes of the plug base body to tightly rest against the contact planes at the corresponding mounting holes of the socket base body, so the connection effect is improved and the problem that a circuit board can not be firmly fixed in the equipment is effectively solved.

Description

A kind of electric connector plug body

Technical field

The utility model relates to the circuit connector technical field, relates in particular to a kind of electric connector plug body.

Background technology

In control panel, often use electric connector that the signal of telecommunication is reached another piece circuit board from a circuit board, traditional electrical connector plug matrix is inserted on the thick circuit board of 2mm, the socket matrix is inserted on the thick circuit board of another piece 2mm, in use plug body is inserted need behind the socket matrix with supporting screw and nut by electricity in succession the mounting hole site at device two ends circuit board is fixed in the equipment.Because plug body installing hole end face 3 positions of electric connector are low than plug hole end face 4, material thickness is not enough, with screw and nut with plug body with after the socket matrix cooperates, the contact-making surface at two matrix mounting hole site places is contact (referring to Fig. 6 and Fig. 7) not, cause the plug body distortion, influence connects effect, to making circuit board fixing not firm in equipment, circuit signal transmission is unstable, and circuit board is also because can not be firm be fixed on greatly reduces its due useful life and use electric property in the equipment.

The utility model content

The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, unreasonable structure at the mounting hole site at the plug body two ends of existing electric connector proposes a kind of electric connector plug body, make it can improve the connection effect, effectively solve circuit board fixing not firm problem in equipment.

The purpose of this utility model is finished by following technical proposals: a kind of electric connector plug body, in this matrix, be provided with the plug hole that matches with the socket matrix, be respectively equipped with installing hole on the plug hole both sides, it is characterized in that described installing hole end face is concordant with the plug hole end face, when plug body and socket matrix matched, the corresponding installing hole end face with the socket matrix of plug body installing hole end face offseted.

The utility model creatively uses " I-beam " in the physics to increase the principle of support strength effectively, original irrational mix is carried out substantial improvement, the PBT material at mounting hole site place, former electrical connector plug matrix two ends is increased to 11.6mm by original thickness 5.2mm, the installing hole end face is concordant with the plug hole end face, the contact plane that presses down at plug body mounting hole site place is offseted with the contact plane at the corresponding mounting hole site of socket matrix place, the mounting hole site of passing the plugs and sockets corresponding position with 1 screw and nut is fixed on the equipment again, connect effect thereby improve, effectively solved circuit board fixing not firm problem in equipment.

Embodiment

Referring to Fig. 1 to Fig. 5, be provided with the plug hole 1 that matches with the socket matrix in the plug body described in the utility model, be respectively equipped with installing hole 2 on plug hole 1 both sides, described installing hole end face 3 is concordant with plug hole end face 4, we can say that also contact plane with plug body insertion side is at conplane height.After plug body a was inserted socket matrix b, the contact-making surface at two matrix mounting hole site places just had been against together tightly, referring to Fig. 8 and Fig. 9.Because of all having plugged in a circuit board on each plug, the socket matrix, just can be at the mounting hole site place with two circuit boards being fixed on together tightly with a suitably long screw and nut.

Claims (1)

1, a kind of electric connector plug body, in this matrix, be provided with the plug hole that matches with the socket matrix, be respectively equipped with installing hole on the plug hole both sides, it is characterized in that described installing hole end face is concordant with the plug hole end face, when plug body and socket matrix matched, the corresponding installing hole end face with the socket matrix of plug body installing hole end face offseted.
