Abstract
A kind of electric connector comprises insulated substrate and conducting terminal, and insulated substrate is provided with the holding hole that array is arranged; The auspicious son that wherein conducts electricity is that linear electric conducting material is made, and has the contact site that electrically connects with the butt end, is immobilizated in the holding parts of holding hole and is connected contact site and the elastic portion of holding parts, and the axis of conducting terminal wire rod is in same plane.Linear conducting terminal width is less, can further dwindle terminal pitch.
Description
[technical field]
The relevant a kind of electric connector of the present invention refers to a kind of electric connector that is provided with the array conducting terminal especially.
[background technology]
Existing electronic product is typically provided with processor, and is connected to printed circuit board (PCB) by electric connector.Along with the processor degree of integration is more and more higher, electric connector also respective design becomes the array electric connector.In the existing array electric connector, conducting terminal is generally plate stamping and forms, and is installed on laminated structure in the insulating body of electric connector.
Along with the continuous rising of the integrated level of processor, the stitch closeness also increases, and when processor is being pressed conducting terminal, easily causes the short circuit between the conducting terminal.The pancake conducting terminal width of sheet is bigger, also further dwindling of electric connector has been caused restriction.Every adjacent four conducting terminals of traditional array formula electric connector form a square in addition, and this execution mode causes between the conducting terminal fore-and-aft clearance less, easily cause between the sheet conducting terminal of high density electrical connector and form cross-talk, cause the signal misinformation.
Therefore, be necessary to provide a kind of electric connector with novel array conducting terminal.
[summary of the invention]
Main purpose of the present invention provides a kind of electric connector, refers to a kind of electric connector that is provided with the array conducting terminal especially.
For reaching above-mentioned purpose, the invention provides a kind of electric connector, comprise insulated substrate and conducting terminal, insulated substrate is provided with the holding hole that array is arranged; Wherein conducting terminal is that linear electric conducting material is made, and has the contact site that electrically connects with the butt end, is immobilizated in the holding parts of holding hole and is connected contact site and the elastic portion of holding parts, and the axis of conducting terminal wire rod is in same plane.
Compared to prior art, electric connector of the present invention has following effect: linear conducting terminal width is less, can further dwindle terminal pitch.

[embodiment]
See also Figure 1 and Figure 2, electric connector 100 comprises conducting terminal 1, insulated substrate 2, insulating lid 3 and tin ball 4.
See also Fig. 1 to shown in Figure 3, conducting terminal 1 is made by linear electric conducting material, and by round wire or copper wire manufacturing, it has holding parts 11, elastic portion 13 and contact site 15 in the present embodiment.Wherein holding parts 11 is the U-shaped kink, has fixing point 111.Contact site 15 is located at an end of conducting terminal 1, is bent to form by linear electric conducting material, and contact 151 is the bending part of wire rod, and the sharpened surface that forms when avoiding the wire rod end points to cut scratches the conductive part of butt end.Elastic portion 13 is located between holding parts 11 and the contact site 15, and then with the two connection, when conducting terminal 1 pressurized, can realize the strain of conducting terminal 1 by the distortion of elastic portion 13.Can realize the intensity close by diameter less than the linear material of sheet material width with sheet material, and the linear material size is littler, it is less to take up room, thus the spacing that linear conducting terminal can dwindle each terminal with respect to existing sheet material conducting terminal, the probability of reduction conducting terminal short circuit.In the present embodiment, the axis of conducting terminal 1 wire rod is on same plane.
Insulating lid 3 corresponding conducting terminals 1 are provided with the spacing hole 31 of some longitudinal, and wherein the position installs the bigger flank section of width 311, and when conducting terminal 1 passed insulating lid 3, flank section 311 can provide one to pass through for conducting terminal 1 than large space.After electric connector 100 assembling, insulating lid 3 can limit the displacement range of conducting terminal 1 between elastic portion 13 and contact site 15, when conducting terminal 1 cooperates with the butt end, can prevent the short circuit that conducting terminal 1 over-travel causes.Between insulating lid 3 and the insulated substrate 2 space is arranged.Consult Fig. 3 as can be known conducting terminal 1 bending extend its two ends not at same vertical axis, and because conducting terminal 1 two ends are passed insulating lid 3 and insulated substrate 2 respectively, so the spacing hole 31 of insulating lid 3 and insulated substrate 2 correspondences and holding hole 21 be not at same axis.
Tin ball 4 invests the other end of conducting terminal 1 with respect to contact site 15, can realize the electric connection of electric connector 100 and circuit board.
The contact site 15 of electric connector of the present invention is by joint disc grid-array (land grid array, LGA) mode is connected with the butt end, conducting terminal 1 has tin ball 4 with respect to the other end of contact site 15, (ball grid array, mode BGA) and butt end electrically connect by ball pin trellis array.
Among the present invention, front and back two row's holding hole 21 are staggered arranges, and promptly back row holding hole is located at the position after leaning in the middle of the front-seat holding hole, and corresponding conducting terminal and spacing hole are arranged also in this way.Apart from being 0.9 millimeter, the volume of linear conducting terminal is less between the sheet material design front and back terminal that prior art adopts, and its front and rear row longitudinal pitch can be reduced to 0.5 millimeter.Can realize the more high density arrangement of conducting terminal.
