SOCKET CONNECTOR

Abstract

A socket connector comprises a circuit board with a socket part mounted on the outside thereof; a socket shield part; a metal shield plate with a through-slot, on the outside of which the socket shield part is mounted; a shield shell with openings on the wall thereof, forming into a shield chamber for fitting a plug and arranged on the socket shield part; and elastic shielding sheets, snapped into the openings and protruding outwards from the openings, wherein the socket part is inserted into the shield chamber formed by the shield shell through the through-slot of the metal shield plate. The elastic shielding sheets can be easily mounted since they are snapped into the shield shell; due to protruding outwards, the elastic shielding sheets come into contact with the inner surface of the shell of the plug to enable shield when the plug is inserted, so that the surface of the shell of the plug will not be scratched; due to the providing of the metal shield plate, the partial shield around the socket part can achieved, resulting in that the stability of the transmission of the ultrasonic signal is secured.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIGS. 5 to 10, a socket connector in accordance with the present invention comprises a circuit board 5 with a socket part 1 mounted on the outside thereof, and a socket shield part 4, the socket connector further comprises: a metal shield plate 2 with a through-slot, on the outside of which the socket shield part 4 is mounted; a shield shell with openings on the wall thereof, forming into a shield chamber for fitting a plug and arranged on the socket shield part 4; and elastic shielding sheets, snapped into the openings and protruding outwards from the openings, wherein the socket part 1 is inserted into the shield chamber formed by the shield shell through the through-slot of the metal shield plate 2.

Socket parts 1, having a shape of strip substantially, are mounted on the circuit board 5, and the socket part 1 includes tabs 11 formed in the middle thereof. The metal shield plate 2, which is made of aluminum, has a first surface 21 facing circuit board 5 and a second surface 22 facing socket shield part 4, the first surface 21 being parallel to the second surface 22. The metal shield plate 2 is also provided with at least one stepped through-slot, which perforates through the first surface 21 and second surface 22, the number of the through-slots corresponding to that of the socket parts. The stepped through-slot includes a first through-slot 23 with relatively small size and a second through-slot 24 with relatively large size. The shape of the first through-slot 23 matches the outline of the socket part 1. Mount slots 25 are concavely formed on the bottom of the second through-slot 24. Two mount slots 25 are mounted with two mounting portions 3 respectively, and two ends 31 of each mounting portion 3 are fixed in the corresponding mount slot 25 utilizing screws, and the middle part 32 of the mounting portion 3 arches.

The socket shield part 4 comprises a mount plate 41, a shield shell 42, and elastic shielding sheets 44a and 44b. The mount board 41 is fixed in the second through-slot 24 of the metal shield plate 2 with the through-slot through which the socket part 1 traverses. The shield shell 42 extends to the front panel 6 of the host chassis in the direction vertical to the mount board 41, and each wall 421 in the length direction of the shield shell is provided with five openings 43, three pieces of elastic shielding sheets 44a snapping into each opening 43. Each wall 422 in the width direction of the shield shell is provided with three openings 43, a piece of elastic shielding sheet 44b snapping into each opening 43. Two ends of each of elastic shielding sheets 44a and 44b are snapped into the inboard of the openings 43, with the middle part of the elastic shielding sheet arching towards the outside of the openings 43.

When the socket connector is mounted, the two mounting portions 3 are fixed in the two mount slots 25 of the metal shield plate 2, the socket parts are encased by the through-slots of the metal shield plate with the middle parts 32 of the mounting portions 3 pressing against the tabs 11 of the socket parts 1, and each tab 11 and each mounting portion 3 are fastened as a whole with fasteners, so that the two ends of each socket part 1 are respectively fixed on the metal plate 2 by each mounting portion 3.

After the socket connector is mounted, the metal shield plate 2 covers the circuit board 5 and surrounds the socket parts 1, and the socket shield part 4 is fixed on outsides of the metal shield plate 2; the socket parts 1 traverse through the through-slots of the metal shield plate 2 and are inserted into shield chambers 423 formed by the shield shells 42 respectively; the metal shield plate 2 is fixed with the front panel 6 of the host chassis. When a plug 7 is plugged in the socket connector, the arched surfaces of the elastic shielding sheets 44a and 44b come into contact with the inner surface of the shell of the plug 7 to enable shield.

The socket connector according to the present invention has wide applications in fields of movement control of machines, medical diagnostic equipments, automatic control of equipments, video editing and producing facilities, medical imaging systems, industrial and scientific apparatus, testing and measuring equipments, electromechanic microscope and visual systems, CAD/CAM/CAE and computer graphics equipments and so on.

According to the present invention, the elastic shielding sheets 44a and 44b are manually snapped into the openings 43 of the socket shield part 4, so it is easy to mount. The elastic shielding sheets 44a and 44b achieve shield by contacting with the inner surface of the shell of the plug 7, so the outer surface of the plug shell will not be scratched. Thus, the outer surface of the plug shell only needs a surface processing, such as spraying and the like, so the working procedure is simplified. Furthermore, since two ends of each socket part 1 are respectively fixed on the metal shield plate 2 by the mounting portion 3, the force of plug-in or pull-out is transferred to the fixed metal shield plate 2 through the two mounting portions 3 when plug 7 is plugged in or pulled out, so that the circuit board 5 will not subject to the force directly, eliminating the quality risk.

As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalents of such metes and bounds are therefore intended to be embraced by the appended claims.
