Technical field

The utility model is a kind of electric connector, is meant that especially a kind of confession two circuit boards form the Board-to-Board Electrical Connector that electrically connects.

Background technology

As shown in Figures 1 to 4, it is the electric connector structure that uses as female connectors in a kind of known Board-to-Board Electrical Connector, it includes an insulation shell 8, insulation shell 8 is generally the longitudinal bodies of plastic material injection molding, make its have long to a first side wall 81 and one second sidewall 82, the first side wall 81 then links to each other with a diapire 83 with second sidewall, 82 lower edges, make the first side wall 81,

second sidewall

82 and 83 of diapires form one, use Board-to-Board Electrical Connector to insert and engage for another service message connector (figure does not show) to the Plug Division 84 of lower recess.Again, insulation shell 8 is provided with on diapire 83 that plural number runs through diapire 83 and is communicated with Plug Division 84 and extends to the first side wall 81 and the terminal storage tank 85 of second sidewall 82, and terminal storage tank 85 can be positioned in it for a conducting terminal 9 accordingly.And conducting terminal 9 have one can be revealed in the first side wall 81 or second sidewall 82 towards the contact jaw 91 of 84 positions, Plug Division and the outside, outstanding diapire 83 lower surfaces in order to be welded in the welding ends 92 on the circuit board (figure shows), be provided with one to the outstanding positioning convex portion 93 of Plug Division 84 directions in contact jaw 91 near the place, below in addition, when the conducting terminal 9 as Fig. 3 is assembled in the terminal storage tank 85 of insulation shell 8 from bottom to top, but positioning convex portion 93 holdings of conducting terminal 9 break away from insulation shells 8 to prevent conducting terminal 9 in diapire 83 and form interference effect.

Yet as Fig. 4, because it is near 84 places, Plug Division that the positioning convex portion 93 of conducting terminal 9 is placed in the position of diapire 83, because of generally being all metal material, makes conducting terminal 9, its hardness is high far beyond the plastic material of insulation shell 8, so positioning convex portion 93 holdings can be pushed diapire 83 contiguous plastic materials on diapire 83 time and be produced distortion, make diapire 83 heave projection 86 can forming one to Plug Division 84 directions near positioning convex portion 93 places, so will to the service message connector on pegging graft, produce can't fluid-tight engagement influence.

The utility model content

The Board-to-Board Electrical Connector that can not produce material deformation and can suitably gain in strength when the purpose of this utility model is a kind of the assembling is provided.

For achieving the above object, the Board-to-Board Electrical Connector that the utility model provides, comprise that one is microscler insulation shell and complex conduction terminal, this insulation shell has a first side wall, one second sidewall and one connects the diapire on this first side wall and this second sidewall base, make this first side wall, constitute the Plug Division of a recess between this second sidewall and this diapire, and this insulation shell is provided with in addition and runs through diapire and be divided into this first side wall and this second sidewall to be communicated with the plural terminals storage tank of this Plug Division, make these terminal storage tanks supply this corresponding conducting terminal ccontaining respectively, and this conducting terminal and have a positioning convex portion that is placed on this diapire, of the present utility model being characterised in that:

The diapire of this insulation shell is provided with a shrinkage pool with correspondence for the position of the positioning convex portion holding of this conducting terminal adjacent to this terminal storage tank, makes the positioning convex portion of this conducting terminal can be contained in this shrinkage pool and prevents this diapire distortion.

Wherein be positioned at the handing-over edge that this middle the first side wall of this adjacent terminal storage tank and this diapire junction also form an on-right angle, can be in order to strengthen the structural strength of these terminal storage tank both sides.

Wherein be positioned at the handing-over edge that this middle second sidewall of this adjacent terminal storage tank and this diapire junction also form an on-right angle, can be in order to strengthen the structural strength of these terminal storage tank both sides.

Embodiment

The technology that relevant the utility model is for achieving the above object, feature adopted exemplifies a preferred embodiment and conjunction with figs. and is described as follows in section and effect thereof:

Consult Fig. 5 to Fig. 7, one preferred embodiment of Board-to-Board Electrical Connector of the present utility model comprises that one is microscler insulation shell 1 and complex conduction terminal 2, similar with aforementioned known construction, insulation shell 1 also has a first side wall 11, one second sidewall 12 and a diapire 13, make the

first side wall

11,13 Plug Divisions 14 that constitute a recess of second sidewall 12 and diapire, and insulation shell 1 is provided with in addition and runs through diapire and be divided into the first side wall 11 and second sidewall 12 to be communicated with the plural terminals storage tank 15 of Plug Division 14, makes these terminal storage tanks 15 supply corresponding conducting terminal 2 ccontaining respectively.In the same manner, conducting terminal 2 also has a contact jaw 21, a welding ends 22 and is placed in the positioning convex portion 23 on the diapire 13, and different with known construction be in, the diapire 13 of insulation shell 1 supplies the position of positioning convex portion 23 holdings of conducting terminal 2 to be provided with a shrinkage pool 16 adjacent to terminal storage tank 15 with correspondence, make and just can be contained in the shrinkage pool 16 after the positioning convex portion 23 of conducting terminal 2 is assembled as shown in Figure 7, so, diapire 13 promptly can not be squeezed and be out of shape, so can not produce bulge phenomenon and influence the service message connector and enter Plug Division 14 and engage yet.
