Abstract

The utility model provides a card edge connector which can be arranged on the circuit board for butting with an electronic card, wherein a plurality of conductive sheets which have the same shapes and are distributed on the same height are arranged on the electronic card. The utility model comprises an insulating body and a plurality of conductive terminals, wherein at least the heights of the contact parts of two conductive terminals are different; each contact part are in contact with the corresponding conductive sheets. Because the contact parts of the conductive terminals of the utility model are provided with different heights, the subjected force of the electronic card is dispersed; therefore, the insertion force of the electronic card is reduced, the assemblage is simple and the work efficiency is increased.

Description

Bayonet connector

[technical field]

The utility model relates to a kind of bayonet connector, refer to especially a kind of when electronic cards is inserted, the bayonet connector that insertion force is less.

[background technology]

Bayonet connector is widely used in individual calculator and other electronic equipment, and its group is located on the circuit board, and can peg graft for all kinds of electronic cards, electrically conducts so that reach between electronic cards and circuit board.Existing bayonet connector can consult that United States Patent (USP) is announced the 5059133rd, 6210195, No. 5672069 and No. the 515591st, Taiwan patent announcement, these bayonet connectors all have the insulating body of a lengthwise configuration, interface at insulating body is arranged with formation one slot downwards, pegs graft for the electronic cards of specific standard.The two side of the insulating body of slot both sides is provided with the plurality of terminals accepting groove, and plurality of conductive terminals is contained in it.During application, the inserted terminal of electronic cards is housed in the slot of this bayonet connector, reaches with the engaging of current-carrying part of electronic cards by conducting terminal to electrically conduct between electronic cards and bayonet connector.

But along with the fast development of Information technology, the requirement of volume of transmitted data also constantly increases, thereby causes number of terminals to increase.Because the restriction of installing space, the size of bayonet connector can not corresponding increase, so terminal pitch certainly will will reduce, and causes the terminal in the bayonet connector to arrange more and more tight thus.And because of the contact site of terminal all is arranged on sustained height, when electronic cards was inserted, it can be subjected to the pressure of each terminal to it simultaneously, and therefore required insertion force will be bigger when inserting, and made assembling become very difficult.

Therefore, be necessary to design a kind of novel bayonet connector, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of novel bayonet connector, and the insertion force that its need are less just can make electronic cards insert in the bayonet connector, has improved operating efficiency.

In order to reach above-mentioned creation purpose, the utility model bayonet connector, can be arranged on the circuit board being used for and connect with electronic cards, wherein to be provided with some shapes identical and be distributed in the conducting strip of sustained height for electronic cards, this bayonet connector comprises insulating body and plurality of conductive terminals, at least wherein the contact site height of two conducting terminals is inconsistent, and each contact site can both contact with corresponding conducting strip.

Compared with prior art, the utility model bayonet connector, highly inconsistent owing to the contact site of conducting terminal is arranged to, the power that electronic cards is subjected to is disperseed, and therefore, it is very little that its insertion force will become, and makes assembling simple, improved operating efficiency.

[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model bayonet connector is described further.

See also Fig. 1 to shown in Figure 5, the utility model bayonet connector 100 is arranged on circuit board (not icon) and goes up for electronic cards (not icon) grafting, and it comprises an insulating body 1, is housed in plurality of conductive terminals 2,2 ' and one make-up mechanism for card 3 in the insulating body 1.

Insulating body 1 comprises the base portion 10 that a lengthwise extends and is located at a pair of installation portion 14 at base portion 10 lengthwise two ends.Base portion 10 comprises the lengthwise two side 13 that is oppositely arranged and is formed at the central slot 15 of a long and narrow configuration of 13 of this two sides that each sidewall comprises upper surface 11, lower surface 12, medial surface 131 and lateral surface 132.In sidewall 13, be provided with along its lengthwise axial arranging and vertically run through its upper and lower plurality of terminals accepting groove 19 of surperficial 11,12.Each terminal containing slot 19 further offers the opening 18 that communicates with central slot 15 on the medial surface 131 of sidewall 13.

Button mechanism for card 3 is installed on the installation portion 14, and each button mechanism for card 3 comprises a vertical strip main part 31 that extends and is formed on main part 31 tops and detains the inclined arm 32 of mechanism for card 3 diagonally extendings towards another.

Plurality of conductive terminals 2,2 ' is in the corresponding terminal accepting groove 19 of insulating body 1, and it comprises the holding parts that is retained in the accepting groove 19 22,22 ', be bent upwards the opening 18 that extends and further protrude out sidewall 13 from holding parts 22,22 ' enters contact site 21 central slot 15 in, 21 ' and extend sidewall 13 lower surfaces 12 downwards from holding parts 22,22 ' and also can be welded on the circuit board to reach the afterbody 23,23 ' that electrically conducts.Wherein, contact site 21,21 ' is highly inconsistent, and is irregular arrangement, and two relative or adjacent termination contact portions are highly inconsistent for it, can both contact with the electronic cards conducting strip, and the electronic cards conducting strip are the identical setting that distributes.After electronic cards is inserted central slot 15, button mechanism for card 3 can be with firm being connected on the insulating body 1 of electronic cards, the electronic cards conducting strip electrically contacts with the contact site 21 of corresponding conducting terminal 2, and the afterbody 23 of conducting terminal 2 electrically connects with circuit board, thereby reaches electrically conducting between electronic cards and circuit board.

In addition, as preferred implementation, the contact site height of conducting terminal should be in three differing heights at least, makes when inserting electronic cards, and required power is less, is convenient to operation.

In sum, when electronic cards was inserted central slot, because conducting terminal contact site height is inconsistent, the power that electronic cards is subjected to was disperseed, and therefore, its insertion force will diminish a lot, makes assembling simple, has improved operating efficiency.
