Description

Technical Field

[0001] The utility model relates to a through-the-wall electric connector, belonging to the technical field of electric connectors. Background Art

[0002] Electrical connectors and cables are widely used in industries such as manned spaceflight, satellite communications, defense equipment, and automobile manufacturing as the blood vessels for controlling signal transmission and electrical connection of electrical equipment. Conventional current and signal transmission between printed boards is usually achieved by vertical solderless interconnection technologies such as buttons and spring pins. However, the interconnection structure of buttons and spring pins is suitable for signal transmission with shorter board spacing. When the spacing between printed boards is higher, the interconnection structure of buttons and spring pins cannot be used to achieve current and signal transmission between printed boards.

[0003] The Chinese patent document with the publication number CN201421925Y discloses a through-the-wall floating blind plug adapter electrical connector, which is composed of a floating plug end and a fixed plug end, the fixed plug end is fixed on the cabinet panel, the contact pieces of the floating plug end and the fixed plug end are connected by wires, and the shell is connected by a floating riveted tube, wherein the floating plug end and the floating riveted tube are movably connected, the fixed plug end and the movable riveted tube are fixedly connected, the floating plug end and the fixed plug end are butt-connected, and the other two ends are adapter interfaces. Different signal transmission inside and outside the cabinet can be realized through the adapter, blind plugging can be realized for occasions with limited size, and it is convenient and fast to use, and the connection is reliable.

[0004] However, since the floating plug-in end has riveting holes and mounting holes on its outer shell flange, the outer shell flange of the floating plug-in end is relatively large, which results in a larger through-wall hole being required when the floating plug-in end passes through the wall, and the size of the through-wall hole is too large.

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0021] like Figures 1 to 4As shown, a through-the-wall electrical connector described in the utility model includes a socket A1 and a socket B3, wherein the socket B3 is electrically connected to the socket A1 through a plurality of double-ended cables 2, and the socket B3 includes a socket body B30 and two split flanges 32, wherein a fixed flange B31 is provided on the outer shell of the socket body B30, and the two split flanges 32 are connected to the two ends of the fixed flange B31 in a one-to-one correspondence through fasteners. When in use, the socket A1 is fixed to the structural plate by screw locking, and after the socket body B30 and the fixed flange B31 thereon are passed through the wall together, the two split flanges 32 are connected to the fixed flange B31 by fasteners, and finally the socket B3 is locked and fixed to the structural plate by screws; the flange on the socket B3 adopts a split design, which can reduce the size of the through-the-wall hole.

[0022] The split flange 32 is provided with a floating mechanism B34 and a guide hole B33. When in use, the floating mechanism B34 and the floating mechanism A13 have the same shape and size, both including a gasket and a floating rivet tube, and the floating rivet tube can float axially and radially relative to the flange; the structures of the floating mechanism B34 and the floating mechanism A13 are the same as the anti-rotation floating mechanism of the electrical connector provided in the patent document with publication number CN202384571U, which is the prior art and will not be described in detail here.

[0023] The fastener is a screw.

[0024] The socket A1 comprises a socket body A10, a fixed flange A11 is arranged on the outer shell of the socket body A10, and guide holes A12 and floating mechanisms A13 are arranged at both ends of the fixed flange A11.

[0025] The socket A1 and the socket B3 are both butt-jointed with plugs 4 .

[0026] The plug 4 is a vertical surface mount plug.

[0027] The plug 4 includes a plug body 40, the tail pin 41 of the plug body 40 is a vertical surface mount pin, a fixed flange C42 is provided on the outer shell of the plug body 40, and screw sleeves 43 and guide posts 44 are provided at both ends of the fixed flange C42. When in use, the tail pin 41 is surface mounted and welded to the pad on the printed circuit board, and the guide post 44 is matched with the guide hole A12 on the fixed flange A11 and the guide hole B33 on the split flange 32, so as to realize the blind plugging function of the plug 4 with the socket A1 and the socket B3.

[0028] The working principle or use process of the through-the-wall electrical connector described in the utility model is as follows:

[0029] Plugs 4 are welded on two different printed circuit boards. During welding, the tail pins 41 on the plugs 4 are surface mounted and welded to the pads on the printed circuit board. The floating mechanism A13 in the socket A1 is locked and fixed on the structural board by screws. At this time, the socket body A10 and the fixed flange A11 can float together in the radial and axial directions of the floating mechanism A13 relative to the floating mechanism A13. After the socket body B30 and the fixed flange B31 on it are passed through the wall together, the two split flanges 32 are connected to the fixed flange B31 by fasteners, and finally the floating mechanism B34 in the socket B3 is locked and fixed on the structural board by screws. At this time, the socket body B30, the fixed flange B31 and the split flange 32 can float together in the radial and axial directions of the floating mechanism B34 relative to the floating mechanism B34. When the plug 4 is plugged into the socket A1, the guide column 44 cooperates with the guide hole A12 for guided plugging; when the plug 3 is plugged into the socket B3, the guide column 44 cooperates with the guide hole B33 for guided plugging, thereby achieving blind plugging.

[0030] Since both socket A1 and socket B3 are installed in a floating manner, the through-the-wall electrical connector can realize a large floating function. After the spacing between the two printed boards is determined, it is sufficient to use a double-ended cable 2 with a length that is suitable for the spacing, so the through-the-wall electrical connector can realize current and signal transmission between printed boards with large spacing.
