Description

The electronic card coupler trip mechanism

The utility model is a kind of electronic card coupler trip mechanism, refers in particular to the two-part trip mechanism that is integrally formed with furring device on a kind of thrust unit.

Notebook computer is because volume is little, be convenient to portable, therefore trend more and more in vogue arranged, yet just because of its volume is little, assembling space is limited, be difficult in this narrow space the most complete function of assembling, so it is equipped with all usually and accommodates the electronic card coupler that connects the electronics card device, with electronic components such as winding such as memory card, expansion board and hard disk drive.Yet, these electronics card devices are when winding is on electronic card coupler, normally complete or major part is submerged in the computer chassis, and the number of terminals that itself and electronic card coupler connect is quite a lot of, withdrawing from power and the quite inconvenience of enforcement that these electronics card devices often need be bigger, for this reason, be provided with trip mechanism on the existing electronic card coupler, so that the electronics card device is withdrawed from smoothly in electronic card coupler more.Relevant design sees also cases such as No. the 83215629th, 85107204,86205493, TaiWan, China patent application.In addition, because existing electronic card coupler volume is bigger,, will occupies bigger motherboard area and make it not apply to utilize if be directly installed on the plate face of computer motherboard.For saving the limited space of motherboard, industry mostly adopts to make in the mode that furring device is set on the electronic card coupler and keeps certain distance between electronic card coupler and motherboard and can on the motherboard at this place other electron component be set, and relevant design also can be consulted case such as No. the 82211048th, 83208932,86210606, TaiWan, China patent application and be disclosed.Yet, the furring device of these existing electronic card couplers is to be provided with in the single component mode, corresponding mechanism so must be set with winding with it on electronic card coupler, and, as the position of desiring the winding furring device has been provided with other members such as trip mechanism etc., then the winding of these members will cause that the structure of corresponding winding becomes more complicated on the electronic card coupler, and take up room and increase and be unfavorable for assembling.And, will increase the worker station and make assembling operation more complicated because trip mechanism and furring device are placed in respectively on the electronic card coupler.

The utility model purpose is to provide a kind of electronic card coupler trip mechanism, and it can effectively reduce the composition member of whole electronic card coupler, and can reduce structure complexity, make whole winding more rapid easily, and can save assembling space.

The purpose of this utility model is achieved through the following technical solutions: the electronic card coupler trip mechanism includes thrust unit, and the liftout attachment that can on electronic card coupler, withdraw from electronic cards, this thrust unit is that two-part moves back the card design, it includes slide block at least, catch bar, pedestal, elastic component and accommodate the fixedly winding frame portion of aforementioned components, this winding frame portion group is buckled in the electronic card coupler side, it is characterized in that: winding frame portion relies on the side of motherboard to extend towards the bending of motherboard direction and is provided with furring device, this furring device has be connected support portion and the extension that link to each other with winding frame portion and is located at locational support division away from winding frame portion, this support division supports on motherboard, and be provided with joining hole in appropriate position, support division middle part, be locked in the function that wherein also realizes the suitable bed hedgehopping of electronic card coupler for lock member.

According to above-mentioned creation characteristic, this winding frame portion is " U " shape and extends equivalent length along electronic cards grafting direction, and the assembling that one is extended with the corresponding settings of several shielding casings that are buckled in electronic card coupler on the last avris edge of its two relative wall is with the engaging body on the opening.

Owing to adopted such scheme, the winding frame portion of trip mechanism and furring device are for being wholely set, thereby be provided with the complexity that can add furring device simultaneously on the same side of trip mechanism and can not increase the winding structure at electronic card coupler, and can effectively reduce the composition number of components of electronic card coupler.In addition, the thrust unit of trip mechanism is to be made as a modular two-piece design, its compact conformation and help saving assembling space.In addition, the trip mechanism especially assembling of its thrust unit and electronic card coupler is quite effectively simple, therefore will effectively save built-up time.

The utility model is further described below in conjunction with drawings and Examples.
