With reference to the accompanying drawings, the present invention is described in detail.

Shown in Fig. 2 a and 2b, the free end 15 that above-mentioned contactor comprises for the stiff end 11 that is connected with the PCB substrate-side and is used for contact with the electronic unit terminals side, above-mentioned stiff end 11 are connected with free end formation by elastic portion 12 described later connected one-piece type.

Wherein, the effect of above-mentioned elastic portion 12 performances is, strain when contact between electronic unit terminals side and free end 15 removing when contacting, reduces free end 15.

And above-mentioned stiff end 11 can be connected in the PCB substrate-side by conductions such as solderings, and above-mentioned free end 15 can when keeping all the time flat-hand position or slightly acclivitous posture, contact with the electronic unit terminals side.

Above-mentioned stiff end 12 comprises the base 10 of dull and stereotyped form and erects both limiting sections 19 of the form of take the altitude, and the base 10 of this moment utilizes soldering etc. to be fixed on the PCB substrate of mobile phone etc., and the effect of whole jockey is supported in performance.

Above-mentioned limiting section 19 as below accept the part of the contact site 14 of free end 15, play preventing from causing the low effect of elastic portion 12 performances because contact site 14 being applied the loadings more than the regulation such as impact.

That is, when above-mentioned contact site 14 was too much pressed, load was delivered to elastic portion 12, and the performances such as reducing power may descend, and therefore, above-mentioned limiting section 19 stops pressing of contact site 14 at suitable line, thereby can stop elastic portion 12 hydraulic performance declines.

For this reason, above-mentioned limiting section 19 comprises the semicircular arcual component 19c that 2 stay 19a, 19b are it with connection to form and to erect the morphosis of set height in integratedly bending of base 10.

That is, above-mentioned limiting section 19 consists of with " ∩ " shape on the whole.

Above-mentioned free end 15 is as the part that contacts with the terminals side of electronic unit, can be when keeping all the time the flat-hand position or acclivitous posture parallel with the stiff end 11 of downside, tabular surface by contact site 14 described later, carrying out face with terminals side contacts, by this contact, can keep the good contact with terminals side.

This free end 15 is to comprise the morphosis of following part: elastic portion 12, and upwards crooked roundly in the length direction rearward end of the base 10 that is positioned at stiff end 11; Support portion 13 prolongs abreast at end and the base 10 of above-mentioned elastic portion 12; Contact site 14 when the end of above-mentioned support portion 13 upwards prolongs, consists of with the tracing pattern with set curvature, contacts with terminals side.

Namely, from the end of above-mentioned base 10, prolong and form the roundly elastic portion 12 of bending shape, then terminal in the upper end of this elastic portion 12, prolong and form both support portions 13 of measured length, the end in this support portion 13 prolongs and forms the contact site 14 that is roughly the ∩ shape then.

And, on above-mentioned contact site 14, formation has the lug boss 20 of set area and protrusion formation tabular surface, by the tabular surface that consists of with set area like this, namely, contact with the electronic unit terminals side by lug boss 20, therefore can guarantee sufficient contact area, the result can improve switching performance.

A kind of device that can stop the contact site 14 on the free end 15 to be out of shape because of external impact or interference particularly is provided in the present invention.

For this reason, at the vertical wall body 16 of base 10 formation of above-mentioned stiff end 11, vertically wall body 16 vertically erects both take the altitudes in the front side of contact site 14, can stop impact or interference from the front side of contact site 14.

Therefore, because above-mentioned vertical wall body 16 blocks the front side of contact site 14, so, when carrying is mounted on the contactor of circuit board, operator's gloves etc. sandwich the leading section lower end of contact site 14 and above the base 10 between the problem in slit, when giving a plurality of contactors gold-plated, the problem that contactor mutually sandwiches, is entangled with, carrying has been when having mounted a plurality of circuit board of contactor, and the problem etc. that the phase mutual interference occurs between contact site all can solve.

The form that this vertical wall body 16 can form with the base 10 one-piece type bendings from stiff end 11 forms.

For example, can be consisted of by following part: side wall body 17, vertically prolong in the both side ends of base 10, block the side; Front wall 18a is converted into the right angle and prolongs at the front side side end of above-mentioned side wall body 17, blocks the front.

That is, above-mentioned vertical wall body 16 is constituted by the side wall body 17 that is " ┓ " font and front wall 18a's, and this Width both sides that are combined in base 10 respectively possess one, thereby can effectively block the front side of contact site 14.

At this moment, between each front wall 18a of the vertical wall body 16 that is disposed at above-mentioned both sides, can form set interval, the height of this vertical wall body 16 preferably have roughly with stiff end 11 on the similar height of limiting section 19.

On the other hand, in the present invention, except the vertical wall body 16 of as above form, also provide the vertical wall body 16 of other forms.

For this reason, shown in Fig. 5 a and 5b, above-mentioned vertical wall body 16 can vertically prolong both take the altitudes by the leading section at base 10, for example, prolongs into and limiting section 19 similar height, and blocks the front wall 18b formation of contact site 14 fronts.

The front wall 18b of this moment, that is, vertical wall body 16 preferably having the width identical with base 10, and vertically is converted into 90 ° morphosis at front end.

As shown in Figure 3, in the situation of contact, keep the contact site 14 of flat-hand position or the posture that is inclined upwardly to carry out the state that face contacts by lug boss 20 with the terminal of electronic unit in the early stage.

Be pressed into to greatest extent in the situation, at this moment, originally keeping the contact site 14 of flat-hand position or the posture that is inclined upwardly by the elastic force distortion of elastic portion 12,, can keep and the complete contact condition of the terminals side of electronic unit by by in downward slightly.

Certainly, when above-mentioned contact site 14 starts, do not disturb with the vertical wall body 16 that is positioned at the front side fully, so, the contact performance of contact site 14 is not exerted an influence fully.

As shown in Figure 4, demonstrate vertical wall body 16 at this and stop the external impact of contact site 14 sides or the state of interference of putting on.

For example, when carrying is mounted on the contactor of circuit board, the gloves that vertical wall body 16 can stop the operator to wear in advance may sandwich the situation of contact site 14 sides, in addition, in the situation that once a plurality of contactors are carried out gold-plated, vertical wall body 16 situation that can stop in advance contactor can mutually sandwich, be entangled with, and, once carrying in the situation of a plurality of circuit boards that mounted contactor, vertically wall body 16 can stop the interference that may cause between the contactor contact site in advance.

Therefore, the factor that the vertical wall body that possesses on the above-mentioned contactor can stop contact site to deform in advance, the result can prevent the distortion of contact site, by stable reduction, performance is not changed.

Thus, the present invention prevents the distortion of the contact site of contactor, base in the contact site forward position configures side wall construction, thereby can solve contact site is out of shape also and can't recovers because of external impact, the problem that causes contact performance to descend, therefore, by guaranteeing the stability of contact site, can improve reliability and the quality of contactor product.
