Specific embodiment

With reference to Fig. 1, have opening and be used to hold the for example space 110 of the card 200 of PC card or the like according to the card connector 100 of the first embodiment of the present invention.Opening is positioned at the front end place of card connector 100.Card 200 is inserted in the space 110 along directions X through opening.Card 200 has two side surfaces 210, on said side surface 210, forms electrode 212 respectively.

Card connector 100 will block 200 and be electrically connected to the circuit board (not shown).Card connector 100 comprises Insulating frame 10, a plurality of contact 70, locator 80 and a pair of ground strip 90.

See figures.1.and.2, Insulating frame 10 comprises base portion 20, a pair of guide portion 30 and connecting portion 40.Guide portion 30 is extended on directions X, and the space 110 that is arranged to make card connector 100 on the Y direction between guide portion 30.In the guide portion 30 each all has leading section and rearward end on directions X.Base portion 20 connects the rearward end of guide portion 30.Connecting portion 40 connects the leading section of guide portion 30.Basal part 20 is formed with retaining hole 22.

As shown in Figure 2, each guide portion 30 comprises top 34, bottom 36 and guiding wall 32.Guiding wall 32 has top and bottom on the Z direction.Top 34 extends to space 110 from the upper end of guiding wall 32.Bottom 36 extends to space 110 from the lower end of guiding wall 32.Guiding wall 32, top 34 and bottom 36 limit guiding groove 38.(angular) U shape shape of the cross section of guiding groove 38 on the Y-Z plane for tilting, and in the side surface 210 of guide card 200 one.Guiding groove 38 allows card 200 to be inserted into space 110 or ejection from space 110 along directions X.

Connecting portion 40 has lamellar shape, and connects the bottom 36 of guide portion 30.

In the contact each 70 all has horizontal part 72 and vertical component effect 74, so that contact 70 has L shape shape.Horizontal part 72 is inserted into respectively in the retaining hole 22 of base portion 20, and is kept by the retaining hole of base portion 20 22 so that vertical component effect 74 Z upwards when extending below horizontal part 72 extend into the space 110 of card connector 100.

Locator 80 is formed with a plurality of location holes 80.Vertical component effect 74 inserts location hole 82 respectively, and the hole 82 that is positioned keeps.In the present embodiment, locator 80 is connected to Insulating frame 10, and is kept by Insulating frame 10.Locator 80 is near the rear end that is positioned at guide portion 30 on the directions X.

With reference to Fig. 2, each in the ground strip 90 includes the portion of being held 91 and from being held the contact tongue 92 that portion 91 extends forward.Be held portion 91 and be provided with joint tongue piece 93 and engagement fork 94.Engaging tongue piece 93 slopes inwardly.In other words, engaging tongue piece 93 extends with respect to Y direction and Z direction obliquely.Engagement fork 94 on the Z direction to extending below.Each contact tongue 92 has first one 95, second ones 96 and contact site 97.Contact site 97 is between first one 95 and second ones 96.At length, first one 95 extends to contact site 97 forward and upcountry from being held portion 91.In other words, first one 95 is extended with respect to directions X and Y direction obliquely.Second one 96 from contact site 97 forward and stretch out.In other words, second one 96 is extended with respect to directions X and Y direction obliquely.Under the situation of this structure, contact site 97 is positioned at space 110, so that contact site 97 can contact with the electrode 212 of card 200.

With reference to Fig. 2 to Fig. 6, each guide portion 30 has maintaining part 50 and accommodation section 60.Accommodation section 60 and maintaining part 50 whole formation.Accommodation section 60 holds contact tongue 92.Maintaining part 50 keeps being held portion 91.Maintaining part 50 has towards the space 110 recessed grooves.Groove is as joint 52, and said joint 52 engages with the tongue piece 93 that engages of ground strip 90.Maintaining part 50 also has bottom 50a.Bottom 50a forms porose 54.As shown in Figure 5, the portion that is held 91 of ground strip 90 is provided with 91a of pressure fitted portion and bottom 91b.

In in engagement fork 94 is inserted into hole 54, is held portion 91 and is urged into maintaining part 50, contact with the bottom 50a of maintaining part 50 up to the bottom 91b that is held portion 91.The 91a of pressure fitted portion pressure fitted is advanced in the maintaining part 50, so that the portion that is held 91 of ground strip 90 is fixed to the maintaining part 50 of guide portion 30.When being held portion 91 and being inserted in the maintaining part 50, engage tongue piece 93 is held portion 50 on the Y direction inwall to extrapolation.Engaging tongue piece 93 temporarily is out of shape.When the end that engages tongue piece 93 is positioned at 52 last times of joint, the joint tongue piece 93 of distortion returns to its original shape, engages with joint 52 so that engage tongue piece 93.Thereby maintaining part 50 can keep being held portion 91 regularly through engaging tongue piece 93 with the 91a of pressure fitted portion.

With reference to Fig. 3 to Fig. 6, the accommodation section 60 of present embodiment has window 62 and covering part 64.Window 62 Z upwards be arranged near and position above covering part 64.Contact site 97 has top 97b and bottom 97a.When the portion that is held 91 of ground strip 90 is kept by maintaining part 50, have only bottom 97a to protrude in the guiding groove 38 through window 62.In other words, top 97b was covered cap 64 coverings on the Y direction when, bottom 97a convexity was in space 110.

Like Fig. 5 and shown in Figure 6, the covering part 64 of present embodiment forms the part on the top 34 of guiding groove 38.Covering part 64 comprises 64b of protection portion and support portion 64a.

The 64b of protection portion is formed near the front end of guide portion 30.In other words, the 64b of protection portion is positioned on the directions X than contact site 97 more near the opening of card connector 100.Utilize this structure, the 64b of protection portion prevents that second one 96 of contact tongue 92 is out of shape owing to irregular card inserts.

Support portion 64a is positioned on the directions X than contact site further from opening.Utilize this structure, even when on irregular direction, blocking 200 when insert card connector 100, support portion 64a can support the contact tongue 92 of ground strip 90.Thereby, can prevent the distortion of contact tongue 92.In other words, the support portion 64a limited contact portion 97 of covering part 64 motion backward on directions X.

Covering part 64 can only cover the part of top 97b.Yet preferably covering part 64 not only covers the part of top 97b, and covers all parts of top 97b, so that covering part 64 is reinforced, and can prevent the distortion of contact tongue 92 safely.

In addition, the covering part 64 of present embodiment be formed on the Z direction window 62 above.In other words, the covering part 64 of present embodiment forms the part on the top 34 of guide portion 30.Covering part 64 can be formed on the below of window 62.In other words, covering part 64 can form the part of the bottom 36 of guide portion 30.Covering part 64 also can be formed on the above and below of window 62.In other words, covering part 64 can form the part of the top 34 and the bottom 36 of guide portion 30.

The application is based on the Japanese patent application of the JP2008-048854 that filed an application to Japan Patent office on February 28th, 2008, and the content of this application is incorporated this paper confession at this.

Though the preferred embodiment of the invention has been described; But those skilled in the art will recognize that; Under the prerequisite that does not break away from spirit of the present invention, can make other and further revise, and be intended to requirement and fall into whole these embodiment in the true scope of the present invention embodiment.
