Embodiment
About aforementioned and other technology contents, characteristics and effect of the present invention, in detailed description, can clearly present below in conjunction with two preferred embodiments of accompanying drawing.
Before the present invention is described in detail, be noted that in the following description content similarly assembly is represented with identical Reference numeral.
Consult Fig. 4～Fig. 8, described accompanying drawing shows first preferred embodiment of low-height card edge connector of the present invention.Bayonet connector 1 comprises an insulation shell 2 and a plurality of conducting terminal 3.Insulation shell 2 is microscler, and have sidewall 21, that 24, two of card slots that are provided with along its length are positioned at card slot 24 length direction two opposite sides and connect the diapire 22 of the bottom side of two side 21, two retainers 23 that are hubbed at the two ends, the left and right sides of insulation shell 2 length directions.Card slot 24 plugs in order to power supply subcard 8, and described two retainers 23 are held electronic cards 8 in order to button.
First side 211 (medial surface) and one that two sidewalls 21 have an adjacent card groove 24 respectively is positioned at second side 212 (lateral surface) of first side, 211 opposition sides, and is formed with respectively on two sidewalls 21 and a plurality ofly is spaced and extends by each second side, 212 opening and toward corresponding first side 211 and the terminal storage tanks 25 that are connected with card slot 24.Two upright relatively interior sidewall surface 213 in each terminal storage tank 25 locate in the bottom side respectively that indent is formed with a bottom side holding slot 251, and two upright relatively interior sidewall surface 213 top sides respectively indent be formed with a top side guide groove 252.Each top side guide groove 252 contiguous card slot 24 side is a blind end 253, and top side guide groove 252 is not connected with card slot 24.
Each conducting terminal 3 is placed in respectively in each terminal storage tank 25, and has a crosswise fixed section 31 in the bottom side holding slot 251 that is fixedly arranged in the terminal storage tank 25, one end by canned paragraph 31 up bends the stretch section 32 of extension, and the other end by canned paragraph 31 extends the welding section 33 that the general more c-shaped bending of insulation shell 2 extends to insulation shell 2 belows.
The width of canned paragraph 31 is greater than stretch section 32, and the both sides of canned paragraph 32 are formed with hangnail 311, and produces with the internal groove side wall of bottom side holding slot 251 and to interfere fixation, thereby each conducting terminal 3 is fixed in each terminal storage tank 25.
The past card slot 24 direction bendings of the part of stretch section 32, and form a contact site 321 that convexedly stretches in the card slot 24, in order to contact with electronic cards 8.The end 322 of stretch section 32 is T-shaped, and toward probably parallel with canned paragraph 31 away from the bending of card slot 24 directions.Two projections 323 of T shape end 322 are placed in the top side guide groove 252 in the terminal storage tank 25, when electronic cards 8 is not inserted card slot 24, be that the contact site 321 of conducting terminal 3 is not when being subjected to external force, two projections 323 of T shape end 322 are butted on blind end 253 places, make contact site 321 produce a precompression, the positive force when contacting electronic cards 8 in order to increase contact site 321.When electronic cards 8 was inserted card slot 24, contact site 321 promptly was resisted against electronic cards 8, two projections 323 of T shape end 322 along top side guide groove 252 away from card slot 24.By the fixing position of T shape end 322 of top side guide groove 252, the position of contact site 321 can crookedly be offset, and produce best positive force when contact site 321 is contacted with electronic cards 8.In addition, form a guidance part 324 between the contact site 321 and terminal 322, more or less freely when electronic cards 8 is planted.
During assembling, each conducting terminal 3 is inserted in each terminal storage tank 25 toward first side 211 (medial surface) direction by second side 212 (lateral surface) of each sidewall 21 respectively.Make each canned paragraph 31 and T shape end 322 respectively along bottom side holding slot 251 and top side guide groove 252, enter in each terminal storage tank 25 toward first side, 211 directions by second side 212 of each sidewall 21.
In the present embodiment, the welding section 33 of conducting terminal 3 can be welded in circuit board surface.But welding section 33 also can be only through once bending, and promptly welding section 33 extends insulation shell 2 at right angles down bending extension again by canned paragraph 31, and welding section form as shown in Figure 2 can be welded in the circuit board with corresponding perforation.
Consult Fig. 8, the canned paragraph 31 by conducting terminal 3 is the plant direction setting perpendicular to card slot 24, makes the vertical height h3 of canned paragraph 31 promptly equal the thickness of canned paragraph 31, and card slot 24 can significantly be reduced to the vertical height h4 of insulation shell 2 bottoms.In addition, the end 322 of stretch section 32 also is the plant direction setting perpendicular to card slot 24, and the vertical height that bayonet connector 1 integral body is located on the circuit board (not shown) can significantly reduce.
Consult Fig. 9, Figure 10 and Figure 11, described accompanying drawing shows second preferred embodiment of low-height card edge connector of the present invention.This second preferred embodiment and this first preferred embodiment are roughly the same, its difference part is, conducting terminal 3 ' end 322 ' be toward tiltedly going up bending, and each terminal storage tank 25 ' roof face 214 contiguous card slots 24 sides down protrude out and be formed with a stop section 215.When not inserting the electronic cards (not shown), stretch section 32 ' end 322 ' be butted on stop section 215, and make stretch section 32 ' generation one precompression, the positive force in the time of can increasing contact site 321 ' contact electronic cards (not shown).
In sum, the conducting terminal of low-height card edge connector of the present invention has horizontal canned paragraph, and the opening of each terminal storage tank of insulation shell is positioned at the lateral surface of the two side of insulation shell, make each conducting terminal can be by two lateral surfaces of insulation shell, laterally insert in each terminal storage tank of insulation shell, thereby can reduce the height of bayonet connector.Moreover, conducting terminal is formed T shape shown in first preferred embodiment when terminal, also have the height that reduces bayonet connector and increase the effect of the positive force that conducting terminal contacts with electronic cards.
The above only is preferred embodiment of the present invention; can not limit scope of the invention process with this; all fall into any simple equivalent variation of being carried out in claims confining spectrum of the present invention and the invention description context and modification, all belong within protection scope of the present invention.
