Push-push connector with anti-return mechanism

Abstract

The invention provides a push-push connector with an anti-return mechanism which will not damage the push-out state of a card owing to slight vibration. The connector includes: a slider 1, a return spring 3, a pin guide groove 11 and a guide pin 7, characterized in that when the slider of the pin guide groove 11 is at a furthest push-out position, an advancing guide groove part 11A and a returning guide groove part 11B in left and right directions are arranged on two sides of the push-out stop position of the pin guide groove, where a sliding part 7b of the guide pin is arranged; a rising inclination part 20 for damper is integrally provided to make the groove bottom face raise on an initial part of the advancing guide groove part at the push-out stop position; moreover, a pressing spring 13 applying resistance to an uprising action of the sliding part is provided when the sliding part of the guide pin passes through the rising inclination part for damper; and the rising inclination part 20 for damper and the pressing spring 13 apply the movement resistance to the sliding part of the guide pin.

Description

technical field [0001] The present invention relates to a push-push connector with an anti-return mechanism provided with a heart-shaped cam-type push-eject mechanism and an anti-return mechanism for restricting the movement of the push-in side after ejection. Background technique [0002] Conventionally, a card connector using a push-in-eject mechanism that performs a push operation and a pull operation by repeating an operation force in the same direction has been widely used. As a representative mechanism of this push-in-eject mechanism, a so-called heart cam mechanism is widely used (for example, Patent Document 1 - Japanese Patent Application Laid-Open No. 2003-317861). [0003] Such as Figure 8 and Figure 9 As shown, the conventional heart-shaped cam type push-eject mechanism is always pushed out by the return spring 3 arranged between the front end of the push direction side of the slider 1 reciprocating with the card A and the housing 2. Directional afterburner. ...

Problems solved by technology

[0010] As the above-mentioned method of restricting the movement in the pushing direction when the card is in the pushed-out state, although a method of increasing the elastic pressure of the return spring maintaining the pushed-out state has been considered, if the elastic pressure of the return spring is increased, there is a The problem that the necessary operating force for the pushing operation increases and the operability deteriorates

[0011] In addition, in the above-mentioned method of pre-setting the recess for buffering on the edge of the card and letting the buffer spring fall into the recess, the buffer spring is always in pressure contact with the edge of the card. The spring pressure of the large return spring, thus creating the same problem as above
