Invent problem to be solved
The substrate of electric component such as this connector is installed, often is used in the various electronic products, wherein, for example be used in the car body of automobile, be placed in the very high environment of temperature.
In this hot environment, the shell of connector is owing to elongation strain takes place in thermal expansion.But as mentioned above, the material of the shell of connector is how different with the material of substrate, therefore, because the difference of the two thermal coefficient of expansion causes shell and substrate that the distortion of different shape has taken place.Therefore, be fixed on the pin type joint on the shell, and be arranged between the wiring pad on the substrate, might produce dislocation.
Particularly, strengthen the both ends that are set at shell with parts more, in this case, be subjected to that shell is deformed by thermal expansion and the influence of the dislocation that produces the easiliest.For example, adopt above-mentioned L type to strengthen when use parts, owing to shell along with thermal expansion generation elongation strain, be installed in the riser on the side wall of outer shell, be subjected to the abducent power of shell, thereby deform, close to transverse slat.Therefore, when shell returned to the temperature that can not expand, transverse slat was pulled to the riser direction, had produced the power of peeling off mutually with substrate.
By this power, be coated in soft solder between transverse slat and the substrate and can crack etc., transverse slat becomes easily and strippable substrate, and being electrically connected of wiring pad becomes unstable on the pin type joint of connector and the substrate; Simultaneously, the bond strength of the connector on the substrate (peel strength) weakens, the dangerous generation easily that connector comes off from basal disc.
In addition, even adopted enhancing parts described in above-mentioned patent document, also can produce same problem.That is, this enhancing parts are the parts beyond the connecting portion of itself and substrate, are pressed into the shell of connector, are integrated with connector.Therefore, because thermal expansion when on long side direction elongation strain taking place, between the wiring pad of shell and the substrate different with the shell thermal coefficient of expansion, dislocation has taken place when shell, on the junction that joins with substrate, concentrated to have applied very big stress.
In order to prevent this problem, imagination strengthens with parts and the bonding area of substrate, the soft solder use amount that increase is used to engage by enlarging, and improves bond strength.But,, will reduce effective erection space of the electronic unit that is installed on the substrate if enlarged bonding area.In addition,,,, be easy to generate bad connection if stride across a plurality of wiring pattern coating soft solders because the wiring pattern of substrate is very thin if use a large amount of soft solders, therefore not preferred.
In addition, imagination is provided with through hole on substrate, and insert through hole with parts and stablize by strengthening, still, and owing to effective erection space of the electronic unit of the rear side that can make substrate reduces, thus not preferred yet.
In addition, have the such the other side's connector of time image game card to need extract and insert from connector continually, in this case, when the user with game card when connector is extracted, owing to need the distortion connector to extract game card, therefore make connector be applied in the stress of distortion sometimes.At this moment,, therefore connector is weakened with engaging of substrate, cause the problems referred to above because the stress of this distortion can focus on the junction of connector and substrate.

On each of the pair of sidewalls of the two-end part that is positioned at shell 3 long side directions, be provided with the enhancing of making, can take place strain with plate-shaped member with parts 4.Fig. 7 is installed on enhancing on the shell 3 of connector 1 with the stereogram of parts 4; Fig. 8 is its front view; Fig. 9 is its upward view; And Figure 10 is its end view.
Strengthen the outside (below, only use " end face " to represent) that is embedded into the sidewall of the long side direction two-end part that is positioned at shell 3 with parts 4.On two end faces of shell 3, be formed with Embedded Division 10, promptly be provided with the portion that is mounted (with reference to Fig. 1 and Fig. 6) of groove; Strengthen being embedded in this Embedded Division 10, thereby be installed on the shell 3, form one with shell 3 with parts 4.
Strengthening with parts 4, is that the plate-shaped member that will make with copper materials such as brass is processed into specific shape.By adopting copper class material, strengthen the electroplating surface that does not need to carry out stainless grade with parts 4 and handle, therefore when reducing cost, it is good to make when engaging with substrate with the bond strength of soft solder.
As shown in Figure 7, enhancing is provided with installation portion 11 and junction surface 12 with parts 4; Installation portion 11 is installed on the Embedded Division 10 of shell 3; The bottom at junction surface 12 is formed with the composition surface that joins with substrate; Installation portion 11 and junction surface 12 join by extension 13.
The composition surface is provided with the first faying face 12a and the second composition surface 12b; This second composition surface 12b is provided with in opposite directions a pair of, and 12a intersects vertically with this first composition surface, and in the middle of it is clipped in.First composition surface is formed on the tabular wall that joins with extension, is banded face, and bearing of trend is parallel with the short side direction of shell 3.
The second composition surface 12b is formed on the sidewall that constitutes junction surface 12, is the banded face that extends from the limit, two ends of the first composition surface 12a of band shape, and bearing of trend is parallel with the long side direction of shell 3.In the middle of two end limits of the second composition surface 12b, by described later curved surface 12c with first composition surface 12a engage on one side, another side is shell 3 dorsad, along extending from the outwards outstanding direction of shell 3.Promptly the second composition surface 12b is along extending from the outside direction of center line T (with reference to Fig. 2～4), and center line T is by the approximate centre of the long side direction of shell 3.
Therefore, be installed in a pair of enhancing on two end faces of shell 3 with the second composition surface 12b of parts 4, towards the extension of opposite direction.And, though in the present embodiment, be with the center of above-mentioned center line as shell 3, be not limited thereto, also can be center line or median plane along the short side direction of shell along the position of centre of gravity by shell 3.
In addition, be formed with curved surface 12c between the first composition surface 12a and each the second composition surface 12b, the first composition surface 12a engages by 2 curved surface 12c with the second composition surface 12b.In addition, though in the present embodiment, curved surface 12c is mild circular arc, and the cross section at junction surface 12 is the U font, is not limited thereto.For example, curved surface 12c can bend to the right angle.
Compare with the total length in the transverse direction cross section of extension 13, the composition surface at junction surface 12 is that the total length in its transverse direction cross section is longer.Because the bonding area increase with substrate is gone up in 12 lower surface (that is, with the composition surface of substrate) at the junction surface, therefore, be improved with the bond strength of substrate.
In addition, on junction surface 12,, be provided with through hole 12d being positioned at (that is, being connected with the direction of installation portion 11) above distance and the composition surface given size of substrate.Through hole 12d respectively is provided with 2 on junction surface, 2 place 12.One of through hole 12d on each junction surface 12 is provided with along the first composition surface 12a, second composition surface 12b and curved surface 12c; Another through hole 12d is provided with along the first composition surface 12a, another second composition surface 12b and curved surface 12c.Through hole 12d is the cross-drilled hole of growing crosswise, and forms with the composition surface almost parallel.
By this structure, to strengthen when engaging with substrate with soft solder, 12 rise along the surface from the junction surface, and soft solder promptly take place rise to extension 13 at soft solder with parts 4, by soft solder is slipped in the middle of 2 through holes, can suppress soft solder and rise along the surface.Thus, keep an amount of, can prevent reduction with this substrate bond strength by making the soft solder that is coated between substrate and the composition surface.
Secondly, describe with engaging of substrate about connector.Figure 11 is the state of connector mounted on surface on substrate 20 that is used to illustrate with present embodiment.Be provided with the connector 1 of above-mentioned enhancing, be installed in the surface of the substrate 20 that is formed with the regulation wiring pattern with parts 4.On the substrate 20, the position in that a plurality of pin type joints 2 of connector 1 engage has formed wiring pad 21; Simultaneously, with strengthen the position engage with parts 4 on, formed metallic wiring pad 22.On the one hand, to the pad on the substrate 20 21,22, the mode to reflux engages connector 1 with soft solder with substrate 20; On the other hand, on the position of not representing among some figure on substrate, connector engages with other a lot of electric components, thereby forms base board unit.
This base board unit is used to the measuring instrument of automobile etc. sometimes, is in during use in the very high environment of temperature.Under this hot environment, the shell 3 of connector 1 and substrate 20 be owing to elongation strain takes place in thermal expansion, still, the material difference of the two, thermal coefficient of expansion is different.Therefore, with respect to the pad 21 that respectively connects up on the substrate 20, each pin type joint 2 of connector 1 misplaces easily; And with respect to the pad on the substrate 20 22, enhancing misplaces easily with the position at the junction surface 12 of parts 4.Being installed on enhancing apart from two ends farthest, center of shell 3 with on the parts 4, the amplitude maximum of this dislocation takes place particularly.
To this, in the connector 1 of present embodiment,, therefore, as shown in Figure 4, between the extension 13 of enhancing usefulness parts 4 and the end face of junction surface 12 and shell 3, formed gap S because extension 13 does not join with shell 3.That is, on the part of two end faces of shell 3,, be provided with the notch of depression in order to form above-mentioned gap S.Therefore, this gap S plays a role with the strain field of parts 4 as strengthening, and absorbs the dilatancy of shell 3.Promptly, because above-mentioned shell 3 is different with the thermal coefficient of expansion of substrate 20, strengthen with parts 4 when the long side direction deflection of shell 3 deforms, extension 13 can flexibly deform at gap S, therefore might make the stress of the junction that affacts junction surface 12 and substrate 20 obtain relaxing.
Figure 12 is used for explanation in the present embodiment, and the shell of connector 13 is because thermal expansion and the key diagram of state during along long side direction generation elongation strain.As shown in figure 12, compare with the elongation strain of substrate 20, the elongation strain that shell 3 takes place is big, with respect to substrate on the position at the junction surface 12 that joins of pad 22, extruding when being installed in installation portion 11 (with reference to Figure 11) on the shell 3 and being subjected to this shell 3 because of thermal expansion generation elongation strain, right side to Figure 12 misplaces, and extension 13 is thereupon in gap S deflection generation strain.By this strain, the stress that is attached on the junction between the pad 22 of junction surface 12 and substrate 20 is alleviated.
Particularly, in the present embodiment, 2 second composition surface 12b and curved surface 12c (with reference to Fig. 7) by extending along extension 13 deflection directions can keep engagement state more strongly to above-mentioned stress; Simultaneously, can prevent to be accompanied by the strain of extension 13 and the torsional deformation that takes place, strengthen bond strength with substrate 20.In addition, among Figure 12, in order to show the dislocation that produces by the thermal expansion of shell 3 and substrate 20 more than you knowly, be benchmark with the junction of junction surface 12 and pad 22, the dislocation that the elongation strain when dotting because of thermal expansion produces.
In addition, as mentioned above, the enhancing in the present embodiment engages with substrate by the first composition surface 12a, the second composition surface 12b and curved surface 12c with parts 4; For example the other side's connector is being inserted in the opening 5 of connector 1, even in the external force that is subjected on the face parallel, twisting to rotation direction with substrate, and classify fulcrum as and the situation of the external force that upwards pushes away etc. with respect to substrate and at above-below direction with one in the two row pin type joints 2, by the first composition surface 12a or the second composition surface 12b that extends along mutual near vertical direction, and with the two curved surface 12c that joins, structurally be improved with the bond strength of substrate, can slow down the defective mode that it is peeled off from substrate.In addition, in the present embodiment, though what adopt as electric component is smt connector, be not limited in this, the DIP switch of mounted on surface on substrate etc. are suitable for too.
Then, by Figure 13 and Figure 14, the variation of described enhancing with the junction surface 12 of parts 4 described.In the embodiment of the present invention of Fig. 1～shown in Figure 12, junction surface 12 is provided with a pair of second composition surface 12a in opposite directions, and its cross section is the U font, but the form at junction surface 12 is not limited in this, can also adopt as Figure 13 and form shown in Figure 14.
