The utility model contains an insulation body. A plurality of slots and terminals are equipped on the insulation body. Wherein, every terminal is installed in the corresponding slot on the insulation body, and the two ends of every terminal are fixed on the insulation body.

Description

Electric connector

Technical field

The utility model relates to a kind of electric connector, and particularly a kind of being applicable to forms the electric connector that electrically contacts between card-type electronic data logging medium and the circuit board.

Technical background

With reference to the 1st figure, the novel patent announcement the 568th, 394 of TaiWan, China discloses a kind of traditional SIM (SubscriberIdentity Module, user's status recognition module) card connector, and it comprises insulating body 5 and plural terminals 6.Insulating body has a faying surface 50 and assembling face 51, and faying surface is provided with perforate 52.Terminal has contact site 60 and elastic portion 61, and the contact site is above faying surface.In this connector, terminal is fixed in insulating body as " cantilever beam ", and an end of terminal 6 is attached to insulating body, and the other end then is unsettled.

Yet, if the user often inserts SIM card electric connector and with SIM card when electric connector is extracted out, terminal is because the unsettled permanent deformation that very likely takes place of an end causes loose contact between terminal and the SIM card conduction region.

The utility model content

Main purpose of the present utility model provides a kind of electric connector of novel structure, and its terminal two ends all are fixed, and can not deform in using repeatedly, improves the life-span of using.

Another purpose of the present utility model provides a kind of electric connector of novel structure, can be widely used in the digital electronic device of various reception cassette electronic bits of data recording mediums.

The purpose of this utility model realizes in the following way:

One insulating body is a microscler slice plastic assembly, is provided with the seam on a plurality of parallel to each other and upper and lower surfaces of conducting on insulating body.

A plurality of terminals are to be formed by the good alloy punching of conductivity, bending.Each terminal all comprises first extension, inverted U-shaped contact-segment, second extension, bending section and welding section.

Each terminal is positioned at the seam of its insulating body, and first extension, second extension are passed through and imbedded in the insulating body, is positioned at outside the insulating body and bending section and welding section pass insulating body one side.

Being provided with at least two reference columns at lower surface can be positioned insulating body on the circuit board.

Because insulating body is fixed at the two ends of terminal, when the contact-segment of conducting terminal was used for contact with the SIM card conduction region, it is less that terminal produces displacement, not deforming in the use repeatedly, can improve the life-span of use greatly.

The electric connector of the novel structure that the utility model provides, simple in structure, easy to use, can be installed in the mobile phone, be used for realizing electrical contact the between SIM card and the circuit board; Simultaneously, the electric connector of novel structure of the present utility model also can be applicable to the digital electronic device that PDA, digital camera etc. receive memory card.

Embodiment

About content of the present utility model, characteristics and effect, the detailed description with the preferred embodiment of conjunction with figs. can clearly present.

With reference to figure 2, be the schematic perspective view of the preferred embodiment of electric connector of the present utility model, electric connector 1 comprises insulating body 2 and a plurality of terminal 3.

Insulating body 2 is a microscler slice plastic assembly, and the about 0.5mm of its thickness comprises: upper surface 21, lower surface 22, two width side surfaces 23 respect to one another, and two length side respect to one another surfaces 24.

The seam 20 on a plurality of parallel to each other and upper and lower surface of conducting that is provided with on the insulating body 2, convenient for explaining orally, referring to shown in Figure 3, we will stitch 20 and be defined as the space that is surrounded by first wall 201, second wall 202, the 3rd wall 203 and wall 204, wherein first wall 201, second wall 202 are respect to one another than shortwall, and the 3rd wall 203, wall 204 are respect to one another than longwell.

Terminal 3 is the assemblies that formed by the good alloy punching of conductivity, bending, and it comprises first extension 31, inverted U-shaped contact-segment 33, second extension 35, bending section 37 in regular turn, and welding section 39.

In manufacture process, the utility model is with ejaculation (insertmolding) technology of generally being familiar with known to this operator of imbedding a plurality of terminals 3 to be installed in the insulating body 2.So, each terminal 3 all is positioned at its corresponding seam 20, and first extension 31 of its terminal is run through, and first wall 201 is imbedded in the insulating body 2, second extension 35 is run through second wall 202 and imbedded bending section 37 and welding section 39 in the insulating body 2 and then be positioned at the middle part that insulating body is 2 outer, contact-segment 33 just in time is positioned at the seam 20 of insulating body 2, a little more than the upper surface 21 of insulating body 2.In brief, each terminal 3 all is installed in its corresponding seam 20, and its two ends are fixed in the insulating body 2.

Referring to Fig. 4, be the side-looking user mode schematic diagram of electric connector, the contact-segment 33 of terminal is to be used for contacting with the SIM card conduction region, when it contacts with SIM card, down maximum displacement is 0.3mm, less than the 0.5mm thickness of this insulating body 2, so can not touch circuit board.

39 of the welding sections of terminal are to be used for being welded on the circuit board.

Lower surface 22 at insulating body 2 is provided with at least two reference columns 221, and insulating body 2 is positioned on the circuit board by this.

The advantage of the electric connector that the utility model provides is, because terminal 3 two ends are subjected to the support of insulating body 2; Therefore the unsettled terminal compared to the traditional electrical connector comes comparison, and the electric connector 1 that the utility model provides can bear the more frequent card motion of insert/taking out, and can not deform, and has long useful life.

In addition, the manufacture process of the electric connector that the utility model provides is also more simplified than prior art, and manufacturing cost is lower.

In addition, according to the utility model, the application of electric connector 1 is not exceeded with SIM card, and the utility model also can be applicable to the digital electronic device of various reception cassette electronic bits of data recording mediums, and the scope of application is more extensive.

The above person of thought; it only is preferred embodiment of the present utility model; when not limiting the scope that the utility model is implemented with this, promptly all simple impartial variations and modification that is done according to the utility model description are all the utility model claim protection range and contain.
