Socket for connection

Abstract

The invention provides a connector with lower back for connecting substrates. A socket contact (5) has a latch pin connection part (54) with front end positioned in a deep-inserting part to form a contact deformation preventing part (56); a latch pin contact part (55) is disposed projected on the latch pin connection part; a spring part (53) is formed in the center part of (52); an embedding concave part (31) is formed on the socket casing (33); an inserting hole (3b) for spring part is disposed on the fixing part (34); a notch part (3b) for causing it possible for the contact deformation preventing sheet part to move back and forth is disposed on the deep-inserting part side inside the fixing part; the latch pin (2) is composed of a latch pin casing (21) and a latch pin contact (4); one end of the latch pin contact (4) is positioned on outside of the latch pin casing (21), the other end is positioned on the side of the latch pin casing (21) oppositely to the latch pin contact to form a socket contact part (42); and the center part is formed on the fixing part (43) fixed on the latch pin casing.

Description

technical field [0001] The present invention relates to a connection socket used in a connection connector that can electrically connect printed wiring boards to each other or that can electrically connect an electrical module to a printed wiring board. Background technique [0002] Electronic equipment such as home appliances includes a printed wiring board on which electronic components are mounted. However, since the electronic components are mounted on only one printed wiring board, the area of ​​the board increases. Therefore, there are cases where a plurality of small boards are stacked and arranged. Constitute the condition of the device. In this case, it is necessary to electrically connect the overlapped printed wiring boards to each other with a plurality of connection terminals, and to use a multi-pole connector for board-to-board connection for electrically connecting the printed wiring boards to each other. [0003] The connection connector used for this purpos...

Problems solved by technology

Therefore, since the spring force acting as the contact pressure applied when the plug contacts 260 come into contact is the base end portion of the first spring contact piece 224 and the configuration that deforms the contact portion 228 with the point A as the starting point of U-shaped bending as a fulcrum, Therefore, increasing the thickness of the socket 203 in order to obtain the spring force at the U-shaped bending part has the problem of becoming an obstacle to lowering the profile.

[0027] In addition, since the contact portion 228 becomes a free end and moves without restriction when fitting, the contact with the contact portion 228 is good, so it has the function of contacting the plug. Point 260 is provided with a second spring contact piece 264 with a spring force, and must be formed in such a way as to obtain good contact
