Abstract
An electronic card connector comprises an insulation housing, a card returning mechanism assembled inside the housing, a terminal module and a detection device, wherein the housing is integrated into a whole by insulation material which comprises an upper wall, a lower wall, a front wall, a first wall and a second wall, the walls jointly circle a hollow box typed cube with an electronic card planted inlet. The front wall is close to one side of the first side wall and is provided with a harbor part that harbors the card returning mechanism, the lower wall is provided with a U-shaped gap that assembles the terminal module. In addition, the foursquare positions of the external surface of the lower wall is provided with a positioning convex table and a positioning convex button, and the intersection of the lower wall and the second side wall is provided with a harbor groove that harbors the detection device. As the housing is an integrated forming, the disadvantages of numerous assembly components, numerous contacts and easy escaping are avoided, the purpose of stability and reliability is achieved, and the structure is simple as well.
Description
[technical field]
The relevant a kind of electronic card coupler of the utility model refers in particular to a kind of electronic card coupler with improvement shell.
[background technology]
At present, electronic card coupler is widely used in various portable digital electronics in a large number, as mobile phone, PDA(Personal Digital Assistant), digital camera etc., its structural design focuses on reaching best stability and to be connected effect, course of processing time and labour saving and cost of manufacture low.With the electronic card coupler shell, present way mostly is to be divided into two parts up and down according to actual size or internal configurations earlier, is engaged fixing again in modes such as spot welding, rivet or screws.Correlation technique can be consulted Chinese utility model patent CN No. 2358570, this connector shell is divided into the plastic cement body and covers shell, be provided with two opening draw-in grooves in the front end both sides of plastic cement body, two tabs corresponding with covering the shell front end are interlockingly connected, cover enclosure lid like this on the plastic cement body, form the receiving space of accommodating electronic cards.
Really, this kind structure can be assembled into the monolithic case of accommodating electronic cards, but because its parts are more, and contact is also many, if wherein have a size different slightly, then can cause the difficulty of fit on.Secondly, the area of the upper and lower shell of electronic card coupler is big, on the make reaches coplanar requirement and be to be difficult for overcome very much difficulty.Once more, because the upper and lower sheathing material difference of correlation technique, the thermal coefficient of expansion difference when causing being subjected to high temperature in manufacturing process, produces the internal stress pullled mutually and flexural deformation.Above problem can be brought the difficulty and the negative effect that is connected effect in the assembling inevitably.
[summary of the invention]
The purpose of this utility model be to provide a kind of part few, assemble reliable electronic card coupler.
The purpose of this utility model is achieved in that the utility model comprises insulation crust, is assembled in trip mechanism, terminal module and arrangement for detecting in the shell.Described shell is one-body molded by insulating material, comprising: upper wall, lower wall, antetheca, first and second sidewall, above-mentioned each wall surround one jointly and have the box-like cube of hollow that electronic cards is pegged graft and entered the mouth.Be provided with the opening of rectangle near the first side wall and electronic cards grafting porch at the shell upper wall, be provided with a gland that covers this rectangular aperture therewith accordingly, and antetheca is provided with the resettlement section of accommodating trip mechanism near a side of the first side wall, and lower wall then offers the U-shaped breach of assembling terminal module.In addition, four jiaos of places of lower wall outer surface are provided with the protruding button of positioning boss and location, and are provided with the accepting groove that holds arrangement for detecting in the intersection with second sidewall.
Compared with prior art, advantage of the present utility model is: this kind electronic card coupler shell is one-body molded, not only avoided the manufacturing process of common prior art loaded down with trivial details and to make the product error big, or the disappearance that easily gets loose of the connector shell integral body that assembles, it is many also to have overcome assembling parts, and contact is many, the shortcoming of assembling difficulty, effectively reach solid and reliable purpose, and simple in structure.

Fig. 3 is another angle schematic diagram of Fig. 2.
[embodiment]
Please refer to shown in Figure 1ly, the utility model electronic card coupler comprises shell 1, be mounted on trip mechanism 2 in the shell 1, terminal module 3, arrangement for detecting 4 and with the fixing welding foot 6 of public printed circuit board (PCB) (not label) welding.
In the present embodiment, shell 1 is the box-like cube of hollow, one-body molded by insulating material, comprise upper wall 12, lower wall 14, antetheca 15, the first side wall 17 and second sidewall 18, above-mentioned each wall surrounds the receiving space (not label) that can accommodate electronic cards jointly, in addition, offer electronic cards interface 5 at shell 1 over against the other direction of antetheca 15.
Antetheca 15 is near a side of the first side wall 17, be provided with the resettlement section 10 of accommodating trip mechanism 2, this resettlement section 10 comprise the cross section semicircular in shape of offering along lower wall 14 inner surfaces groove 102, guide channel 104 that the cross section is square, accommodate mouthfuls 106 and over against groove 102 and run through the hitching post hole 108 of upper wall 12.
In addition, first and second sidewall 17,18 outsides are provided with several welding foot accepting grooves 19, to accommodate welding foot 6.
3 employings of terminal module are imbedded ejection formation (Insert molding) technology and are made, and comprise the first terminal module 30, the second terminal module 32 and conducting terminal 34.Wherein the first terminal module 30 and the second terminal module 32 are respectively equipped with two independences and essentially identical first and second noumenal seat 300,320 of structure.Two noumenal seats, 300,320 both sides all are provided with the card wing 36, and wherein the end of second noumenal seat, the 320 card wings 36 is provided with lug 322, and lug 322 is provided with overhead kick portion (not label).Terminal module 3 is filled up U-shaped breach 142 fully after draw-in groove 144 insertions of U-shaped breach 142 both sides.
