Description
[technical field]
The utility model is relevant a kind of bayonet connector, relates in particular to a kind of improvement of insulator structure of bayonet connector.
[background technology]
Bayonet connector is widely used in personal computer 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 be consulted United States Patent (USP) and announce the 5th, 059,133,6,210,195,5,672, No. the 515591st, No. 069 and Taiwan patent announcement, these bayonet connectors all have the insulating body of a lengthwise configuration, are arranged with downwards at the interface of insulating body and form a slot, peg 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.In the time need adopting bigger electric current in the course of the work, the terminal of bayonet connector temperature in signals transmission is higher.So terminal is arranged closely, and the heat dissipation problem of bayonet connector inside seems particularly important.Please cooperate and consult United States Patent (USP) and announce the 5th, 672, No. 069, the heat in these bayonet connectors usually on the sidewall by insulating body set terminal containing slot dissipate to the external world, these terminal containing slots connect the upper and lower surface of sidewall, and are provided with opening on side wall inner surfaces.But in the bayonet connector use, be installed on the circuit board, cause the closure of openings of terminal containing slot on the sidewall bottom; And electronic cards is housed in the slot, causes the opening of terminal containing slot on side wall inner surfaces to be sealed by electronic cards.Thereby the efficiently radiates heat zone of internal heat is mainly the opening of terminal containing slot in top side wall during bayonet connector work.Obviously, these narrow and small heat dissipation region can't make the heat of bayonet connector inside dissipate fast, the heat accumulation that can't distribute will cause infringement to a certain degree to the insulating body that plastic material is made in insulating body, be unfavorable for using, and may make the insulating body distortion when serious.
Therefore, be necessary described bayonet connector is improved to overcome described defective of the prior art.
[utility model content]
The purpose of this utility model is to provide a kind of bayonet connector, and the terminal containing slot of its insulating body has bigger heat dissipation region, and the heat that helps bayonet connector inside in time dissipates.
For achieving the above object, the utility model adopts following technical scheme: bayonet connector comprises insulating body and plurality of conductive terminals.Insulating body has a base portion, base portion comprises the sidewall that is oppositely arranged and is formed at the central slot that is used to accommodate the electronic cards insertion end between the two side, is provided with the plurality of terminals accepting groove and is connected with terminal containing slot and runs through some passages of respective side walls lateral surface in sidewall; Plurality of conductive terminals is housed in the corresponding terminal accepting groove of insulating body, it comprise the contact site that can electrically contact with the insertion end of electronic cards and from contact site extend can with the afterbody of circuit board electric connection.
Compared with prior art, the utility model bayonet connector has following beneficial effect: bayonet connector is provided with the some passages that communicate with terminal containing slot and run through the lateral surface of sidewall at the sidewall of insulating body, thereby effectively increase heat dissipation region, the heat that helps in the bayonet connector in time dissipates, and avoids Yin Wendu too high and bayonet connector is impacted.
