Patent documentation 1: Japanese Patent Publication 6-68352 communique

Summary of the invention

But, in the method that bolt 5 is set of prior art as shown in Figure 4, for as bolt 5 is fixed on to the structure on housing 4, be formed in the both sides formation slot 6 of housing 4 and the structure in this slot 6 is inserted in the top of bolt 5.Therefore,, in order to ensure the maintenance intensity of inserting the bolt 5 in slot 6, be necessary to increase in the both sides of housing 4 thickness t of sidewall 4a.

But, in electronic instrument, conventionally require its miniaturization, in connector 3, be also like this.From such a viewpoint, the thickness t of the sidewall 4a of increase housing 4 is not preferred.

On the other hand, technology is as described in Patent Document 1 such, if by surround housing above and the outer cover of side be fixed on the structure on printed base plate, so, housing itself can be sought miniaturization.

However, if as the forming above that is surrounded housing by outer cover, the height of connector only increases the degree that outer cover is set, and aspect the low level of connector, also exists herein room for improvement.

The problem of the technology of the present invention based on such is made, and its object is, provides a kind of and can guarantee fully with respect to the constant intensity of printed base plate and make the electrical cnnector of connector miniaturization.

The electrical cnnector of the present invention of making under related object is characterised in that, possesses housing, is contained in contact in housing, a pair of foot of stationary housing and extend and connect the framework of a pair of foot along at least one side of housing.

Although the purposes to such electrical cnnector is not carried out any restriction, such electrical cnnector can as for example connect portable telephone terminal battery component electrical cnnector and use.Such electrical cnnector is arranged on printed base plate, by the portion of terminal of battery component etc. is urged to the side of electrical cnnector, thereby is electrically connected with the contact remaining in housing.

Now, the foot being integrally togather by framework, by this framework is extended along at least one side of housing, can make the fixation of housing to printed base plate.In addition, by making framework not above housing, but along side, thereby avoid hindering the low level of electrical cnnector.

In order to be electrically connected with connecting objects such as battery components, make a part for contact expose and arrange in the side of housing.Although can framework be set along arbitrary side of the side of housing, preferably along the side of exposing with contact, relative another side arranges.Because battery component etc. is urged to the side that contact exposes, thereby by making framework along relative another side, the side of exposing with contact, can support from the rear side of housing the pushing force that is acted on housing by battery component etc. by framework.In addition, can also avoid part and framework that contact exposes to interfere.

Although can framework be fixed on housing by any structure, the side preferably having by inserting housing is fixed on the fixed part on housing.Like this, by framework being inserted to the side of housing, framework can be fixed on housing reliably.In this case, by making framework along relative another side, the side of exposing with contact, thereby framework is inserted to another side, i.e. the rear side relative with battery component etc., can prevent from causing housing and framework to come off because of the pushing force of battery component etc. effectively.

Preferably, on housing, be formed with multiple contact slots that hold multiple contacts, and, be formed with each other next door at the contact slot adjoining each other, in this case, by fixed part is inserted in the recess forming on next door, thereby framework is fixed on housing.

Now, preferably fixed part has with respect to the central part of the Width of the side of housing and symmetrical a pair of tine by a pair of tine being pressed into the side of housing, thereby is fixed on framework on housing.By possessing a pair of tine, become with respect to reverse framework direction power and firmly structure.

And preferably fixed part is configured near of the central part of the Width of the side of housing.Thus, can effectively support the pushing force that is acted on housing by battery component etc. by framework.

Preferably, under state housing being fixed on fixed object (printed base plate etc.), fixed part is with respect to the central part of the side of housing and be configured in a side of leaving from fixed object.,, if to be fixed on a side on the fixed object of printed base plate etc. the bottom surface as housing, to insert fixed part in housing with respect to the central part of the side of housing and be configured in the top of housing.Generally speaking, contact is from being fixed on base end part side direction printed base plate and leading section side and width diminishes.Meanwhile, on the top of housing, can thicken the next door between contact slot, by the fixed part of framework is inserted in herein, just can firmly fix framework thereby do not expand housing.

According to the present invention, because at least one side of the housing along electrical cnnector arranges the framework that a pair of foot of stationary housing is connected, thereby can make the fixation of housing to printed base plate.In addition, by making framework not above housing, but along side, the low level of electrical cnnector can be avoided hindering, the miniaturization of electrical cnnector can be contributed to.

And, on housing, be formed with multiple contact slots that hold multiple contacts, and, be formed with each other next door at the contact slot adjoining each other, in this case, by fixed part is inserted in the recess forming on next door, thereby do not need the special space for fixed frame, in this, also can contribute to the miniaturization of electrical cnnector.

In each contact slot 21, maintain the contact 30 of specified quantity.In the present embodiment, in 3 contact slots 21, be arranged in central contact slot 21, hold and maintain 1 contact 30, be arranged in the

contact slot

21,21 of both sides, hold and maintain the contact 30 that front end branches into respectively 2.

As shown in Figure 2, each contact 30 is made up of conductive material, and the bottom 30a that projects to foreign side (rear) from the back side 20a of housing 20 is welded on the wiring pattern of printed base plate 100.In addition, as shown in Fig. 1 (a) and Fig. 2, in contact 30, with the portion of terminal contact of battery component 200 and the contact site 30b electrically connecting with from be formed on relative with the back side 20a of housing 20 before the peristome 23 of (side) 20b mode that projects to foreign side (front) arrange.

By rearward push the portion of terminal of the side that is located at battery component 200 with respect to the 20b above of housing 20, thereby with respect to the contact site 30b of such contact 30, battery component 200 is installed.In the time that the portion of terminal of battery component 200 contacts with contact site 30b, in order to carry out reliably electric connection, each contact 30 is configured as roughly S word shape etc. as a whole, thereby plays a role power along the 20b above from housing 20 to the projected direction in the front of contact site 30b.

As shown in FIG. 1 to 3, strengthen outer cover 40 by the sheath portion 41 of U-shaped roughly, be pressed into portion's (fixed part) 42 and spigot (foot) 43 forms, this sheath portion 41 is along side 20c, the 20d of the 20aHe Qi both sides, the back side of housing 20, this is pressed into portion 42 and is pressed in housing 20, and this spigot 43 is welded on printed base plate 100.

Sheath portion 41 is formed by banded back support portion (framework) 44 and lateral bolster support

part

45,46, this back support portion 44 extends along the Width (orientation of contact 30) of the back side 20a of housing 20, this lateral bolster support

part

45,46 is connected and forms with the both ends of back support portion 44, and along side 20c, the 20d of housing 20.

And a part for the top of the lateral bolster

support part

45,46 of sheath portion 41 projects to front, be thereunder formed with the receiving portion 47 with bottom surface (, the surface of the printed base plate 100) almost parallel of housing 20.On the other hand, on housing 20, in the position relative with this receiving portion 47, be formed with the protuberance 25 of the thickness approximate same size of outstanding and lateral bolster

support part

45,46, be installed under the state of housing 20 at enhancing outer cover 40, the 25a above of protuberance 25 docks with receiving portion 47.

As shown in Figure 3, be pressed into portion 42 for by base portion 42a be a pair ofly pressed into the roughly U-shaped that pawl (tine) 42b, 42c form, this base portion 42a is along the back side 20a of housing 20, and it is side-prominent towards the housing 20 in front from the two ends of base portion 42a that this is pressed into pawl 42b, 42c.This is pressed into portion 42 and connects with sheath portion 41 via connection part 48.

On the 20a of the back side of housing 20, on the

next door

22,22 between 3

contact slots

21,21,21, be formed with this and be pressed into the bulged-in

recess

24,24 that is pressed into of pawl 42b, 42c.Be pressed in

recess

24,24 by being pressed into

pawl

42b, 42c, thus in base portion 42a and back support portion 44 under the state of the back side 20a of housing 20, will be pressed into portion 42 and sheath portion 41 is fixing.

Spigot 43 extends to side from the bottom of the lateral bolster

support part

45,46 of sheath portion 41, in the time that electrical cnnector 10 is arranged on printed base plate 100, forms along the surperficial mode of printed base plate 100 with bottom surface 43a.

Such enhancing outer cover 40, for example, be bent to form metallic plate by stamping-out and can cheap and easily form.

And, by bottom surface 43a, the 43a of the

spigot

43,43 that is formed at the both sides that strengthen outer cover 40 are welded on printed base plate 100, thereby guarantee the constant intensity of electrical cnnector 10 to printed base plate 100.

At this, although the back support portion 44 of sheath portion 41 also can arrange in the mode of the 20b above along housing 20, as mentioned before, preferably to arrange along the mode of back side 20a.This is because in the time of the pushing force being acted on by battery component 200 from the front of electrical cnnector 10 rearward, effectively support by the sheath portion 41 of the rear side that is positioned at housing 20 housing 20 being pushed by battery component 200.

And according to identical viewpoint, at the back side of housing 20 20a, preferably back support portion 44 is more arranged on top than the center of the short transverse of back side 20a.This is because by back support portion 44 is located to high as far as possible position, can make the back support portion 44 centered by spigot 43 larger to the support moment of housing 20.

In addition, at the back side of housing 20 20a, be preferably pressed into portion 42 and be more positioned at top than the center of the short transverse of back side 20a and arrange.Generally speaking,, for ease of carrying out strain, contact 30 is along with from being weldingly fixed on that bottom 30a printed base plate 100 marches to top and width diminishes.This be because, meanwhile, because the

next door

22,22 between

contact slot

21,21,21 can along with marching to top, width increases, thereby do not make the width dimensions of the profile part of housing 20 increase just can next door 22 on formation be pressed into recess 24.

According to electrical cnnector 10 as above, owing to possessing the outer cover 40 of enhancing, this enhancing outer cover 40 possesses the roughly sheath portion 41 of U-shaped, and the

spigot

43,43 of this enhancing outer cover 40 is fixed on printed base plate 100, thereby housing 20 can be securely fixed on printed base plate 100.At this, be along the side 20c of the 20aHe Qi both sides, the back side of housing 20, the structure of 20d owing to strengthening outer cover 40, thereby there is no need to make to strengthen outer cover 40 above housing 20 and fix, do not hinder the low level of housing 20.

And, strengthen outer cover 40 and be only provided with lateral bolster

support part

45,46 along side 20c, the 20d of housing 20, be provided with integratedly spigot 43 in the bottom of this lateral bolster support part 45,46.So, there is no need the existing structure in slot 6 that the both sides that bolt 5 are inserted in to housing 4 shown in Fig. 4 form, increase the thickness t of the sidewall 4a of housing 4 in order to ensure the maintenance intensity of bolt 5.As a result, the width dimensions of housing 20 can be reduced, the miniaturization of electrical cnnector 10 can be contributed to.

In addition, due to the back side 20a by strengthening outer cover 40 support housings 20, thereby can effectively bring into play and support moment with respect to the pushing force of the battery component 200 of the effect of 20b side direction rear above from housing 20.In addition, also can prevent that the portion that is pressed into 42 from coming off from housing 20.

In addition, because such enhancing outer cover 40 and

spigot

43,43 are integrated, thereby compare with the situation of manufacturing respectively enhancing outer cover and spigot, can suppress cost of parts.In addition, only, by installing and strengthen outer cover 40, just can carry out the assembling of spigot 43 on housing 20 simultaneously.So, there is no need as the existing structure shown in Fig. 4, to assemble 2 bolts 5, can suppress the assembly cost of the part of fabrication stage.

In addition, there is owing to strengthening outer cover 40 portion that is pressed into 42 being pressed in housing 20, thereby can be fixed on reliably on housing 20 strengthening outer cover 40.And, if will be pressed into above portion 42 is more located at than the center of the short transverse of back side 20a at the back side of housing 20 20a, so, along with marching to leading section from bottom 30a, width diminishes contact 30, can increase the width that is formed with the next door 22 that is pressed into recess 24, thereby not make the width dimensions of the profile part of housing 20 increase the portion 42 that just can fixedly be pressed into.In addition, being located at the portion that is pressed into 42 of such position, similarly bring into play with sheath portion 41 effect that housing 20 is kept, being applied by battery component 200 while making housing 20 fall the power of rearward direction, can effectively resist herein.

And, be pressed into portion 42 and there is a pair of pawl 42b, the 42c of being pressed into, be pressed on the

next door

22,22 of both sides of the contact slot 21 that is fixed on the central portion that is positioned at housing 20.Like this, be pressed into portion 42 and possess symmetrically a pair of pawl 42b, the 42c of being pressed into respect to housing 20 center, can anti-torsion and firmly fix housing 20.

25a docking above the protuberance 25 of the receiving portion 47 forming on the lateral bolster

support part

45,46 of sheath portion 41 in addition, and formation on housing 20.Thus, can more effectively bring into play and support moment with respect to the pushing force of the battery component 200 of the effect of 20b side direction rear above from housing 20.In addition, dock with the 25a above of protuberance 25 by making receiving portion 47, can strengthen the location of outer cover 40 with respect to housing 20, improve the assembly precision that strengthens outer cover 40, also obtain the effect of the flatness (coplanarity) of bottom surface 43a, the 43a of easy generation spigot 43.

In addition, in the above-described embodiment, can suitably change shape, the position etc. of the each portion that strengthens outer cover 40.For example,

spigot

43,43 also can be used as the mode being inserted on printed base plate 100 in the through hole forming, and the position that can also make sheath portion 41 or be pressed into portion 42 than the short transverse center of housing 20 more on the lower.

In addition, as long as without departing from the spirit and scope of the invention, housing 20, contact 30 are that any formation all can.

In addition, only otherwise depart from purport of the present invention, just can accept or reject selection or suitably change to other formations the formation of enumerating in above-mentioned execution mode.
