Abstract

A card connector inserted for the electronic card includes an insulating base, a plurality of terminals and two metal components. Each of the metal components consists of a base board, separately fixed on the two ends of the insulating base. A flexible arm is connected to the base board, with the fore-end of the arm can move freely. A bottom board is formed by extending the bottom end of the flexible arm, with a retaining unit installed below the bottom of the base board. When the card receives vibration, the end of the card turns up, and pushes the connection unit to move upward or outward. In this circumstance the retaining unit will also move upward to be fastened with the inner wall of the base board. Therefore, the connection unit and the flexible arm will not be able to move outward, and the electronic card is kept connected tightly.

Description

Bayonet connector

Technical field

The utility model relates to a kind of bayonet connector, refers to a kind of upper surface that can be arranged at a circuit board especially, and the bayonet connector that supplies an electronic cards to plant.

Background technology

Existing bayonet connector is the upper surface that is used to be arranged at a circuit board, and supplies the plant of an electronic cards, electrically connects circuit board and electronic cards to reach.As announce No. 382836 Taiwan patent announcements (application case number: " the electric connector " that 86118731) is disclosed on February 21st, 89 in Taiwan with metal door bolt button, it comprises that a dielectric casing and has the door bolt buckle assembly of door bolt cramp, the door bolt cramp of this door bolt buckle assembly can be buckled in the upper surface of electronic cards (subcard), in order to prevent that electronic cards from popping up, make being inserted on the dielectric casing that electronic cards can be firm.

But, above-mentioned existing bayonet connector, though be provided with the door bolt cramp in order to the buckle electronic cards, this door bolt cramp is an arc lamellar body, when electronic cards is born vibration, the upper and lower swing of rear end meeting of electronic cards, and promotion door bolt cramp makes progress and to outer displacement, door bolt cramp button is held poor effect, thereby compacting snapping electronic cards that can't be certain, therefore electronic cards gets loose easily and pops up, and what electronic cards can't be firm is inserted on the insulating body.

Summary of the invention

Main purpose of the present utility model, being to provide a kind of bayonet connector, and it can make the certain compacting snapping electronic cards of snapping portion of metalwork, holds effect in order to increase button, prevents from that electronic cards from getting loose to pop up.

In order to reach above-mentioned purpose, the utility model provides a kind of bayonet connector, comprising: an insulating body, and it has slot; A plurality of terminals, it is located on the insulating body of the upper and lower edge of slot, and each terminal all has contact site and pin portion, and the contact site is in this slot, and pin portion extends outside this insulating body; And two metalworks, respectively include a substrate, be fixedly arranged on two sides of this insulating body respectively; One elastic arm is to be connected in this substrate, and this elastic arm front end forms free end; One base plate is to extend to form in this elastic arm lower edge, and the prominent stop section of establishing on this base plate, this stop section are positioned at this appropriate intervals place, substrate lower edge below.

The utility model mainly is to be equipped with a stop section on the base plate of metalwork, and this stop section is to be lower than substrate when usual, can not hinder to pull elastic arm and outwards move.When electronic cards is born vibration, the rear end of electronic cards is upturned, and promotion snapping portion upwards reaches when outer displacement, this snapping portion interlock stop section immediately makes the stop section corresponding to the substrate inner edge to top offset, and then makes stop section contact block in the substrate inner edge, make snapping portion and elastic arm outwards to move, snapping portion can be certain compacting snapping electronic cards, hold effect in order to increase button, prevent from effectively that electronic cards from getting loose to pop up.
