Description

The electrical cnnector terminal structure

Technical field

The utility model relates to a kind of improved electrical cnnector terminal structure, relates in particular to a kind of relative both sides of leading portion of the second terminal section by the impact extrusion terminal, so that this second terminal section leading portion is at the thickness of the vertical X-Y plane thickness greater than selected sheet metal.

Background technology

Be applied to the terminal on the connector at present, as shown in Figure 7, be directly stamping forming by the single metal plate material, it comprises: a first terminal section 31 and one second terminal section 32, wherein this second terminal section 32 is to extend from this first terminal section 31 along the X-direction lengthwise and form, by this second terminal section 32 is stretched in the connector, with with telecommunication assembly such as PCMAIC card ((the Personal Computer Memory Card International Association of Personal Computer Memory Card International Association, be called for short PCMCIA)) be electrically connected, because according to the terminal standard specification, this terminal must be selected for use on making and equal perpendicular to the sheet metal of the second terminal section 32 in X-Y plane place thickness t.

Yet in application, the leading portion that removes this second terminal section 32 because of this splicing ear is connected contact-segment with corresponding connector, must meet outside this standard thickness, other part, and do not require its material thickness, therefore make whole Zhi Duanzi as if selecting for use, will increase material cost, therefore improved necessity arranged with the sheet metal of these second terminal section, 32 leading portion same thickness.

Therefore, the applicant proposes utility application number 02255196.4 (electrical connection terminal minor structure) in first forward direction Patent Office, be in the shortcoming that solves aforementioned existing terminal structure, mode with bending, make this second terminal section perpendicular to the thickness of X-Y sheet metal thickness greater than the first terminal section, and conformance with standard thickness.

Summary of the invention

In order to make the electrical connection terminal minor structure better better, the applicant openly goes out a kind of improved electrical cnnector terminal structure.

The purpose of this utility model aims to provide a kind of improved electrical cnnector terminal structure, wherein this terminal is to be made by the sheet metal of single thickness, define that to be formed with X-Y-Z three-dimensional axially, this terminal comprises: the first terminal section and the second terminal section, wherein the latter end lateral margin of this second terminal section is equipped with an inserted tooth portion at least, and original sheet metal thickness of vertical X-Y plane is defined as t1, wherein, the relative both sides of leading portion of this second terminal section, after relative impact extrusion, make the thickness of the vertical X-Y plane of leading portion of this second terminal section be defined as t2, greater than original sheet metal thickness t1, with the thickness that meets standard requirements.

Preferred implementation of the present utility model can be by following explanation and appended graphic, and is able to distinct.

Embodiment

See also Fig. 4 to shown in Figure 6, the utility model relates to a kind of improved electrical cnnector terminal structure, wherein this terminal 100 is to be made by the sheet metal of single thickness, define that to be formed with X-Y-Z three-dimensional axially, this terminal 100 comprises: the first terminal section 1 and the second terminal section 2, wherein latter end 21 lateral margins of this second terminal section 2 are equipped with an inserted tooth portion 211 at least, and original sheet metal thickness of vertical X-Y plane is defined as t1, and the leading portion 22 relative both sides of this second terminal section 2, make to impact extrusion its thickness be defined as t2, thereby make the leading portion 22 of this second terminal section 2 equal the thickness of standard specification greater than original sheet metal thickness t1 perpendicular to X-Y plane.

Making of the present utility model is referring to figs. 1 to shown in Figure 3, be the first terminal section 1 and the second terminal section 2a with this terminal of metallic plate punching moulding thin than standard specification thickness t 1, this second terminal section 2a wherein, be from the front end horizontal-extending of this first terminal section 1 and form, become one not fully the young body 100 of moulding ', at this moment, the young body 100 of moulding ' it does not promptly equal the thickness of selected sheet metal perpendicular to original sheet metal thickness t1 of X-Y plane for this, and less than the standard thickness person of terminal linkage section.

Then, as shown in Figs. 4-6, mode with impact extrusion, make the leading portion 22 relative both sides of this second terminal section 2, two directions up and down are promptly along the Z-direction extension, make after extrusion, the leading portion 22 of this second terminal section 2 in the thickness t 2 of vertical X-Y plane greater than original selected metal material thickness, i.e. original sheet metal thickness t1 of the first terminal the section 1 and making of finished product is finished in moulding.

Terminal 100 disclosed in the utility model, as shown in Figure 6, it is one circular-arc that the upper/lower terminal edge 23,24 in the leading portion of this second terminal section 2 along the Z axle is, or other shape, and the utility model also will not be from limit.

Terminal structure disclosed in the utility model, because in the impact extrusion mode, these second terminal section, 2 leading portions 22 are increased perpendicular to the thickness of X-Y plane, and equal standard thickness, therefore on the sheet metal of selecting for use, just can select the sheet metal manufacturing thin for use, because this terminal is normally with expensive material such as copper and be long ribbon shape and make, therefore when selecting thin metal material making for use than standard thickness, its production cost significantly reduces, and has more the market competitiveness.

The utility model is because the leading portion 22 of this second terminal section 2 is by the relative impact extrusion moulding in its both sides, therefore can improve applicant's disclosed terminal in preceding patent application case (promptly No. 912414899) again, further promote the qualification rate of product again, obvious novel creativity of the present utility model.

Structure disclosed in the utility model, shape can be modified application in not disobeying under spirit of the present utility model and the category, and the utility model also will not be from limit.
