Description

SO-DIMM type memory bar connector

Technical field

The utility model relates to the memory bar connector, in particular for the connector of SO-DIMM type memory bar grafting.

Background technology

Memory bar is a memory storage indispensable in the current PC, it be by a kind of connector that is installed on the computer motherboard finish with computer between be connected.Freely expand the memory size of computer for the convenience of the users, be typically provided with a plurality of connectors on the motherboard, so that free grafting memory bar.

At present, memory bar has following several form: 1. small size J-shaped pin (SOJ, Small OutlineJ-lead), and it is a kind of surface adhering packing, volume is less, does not take up space, and only needs attached on the plate of computer road; 2. single pin memory bar (SIMM, Single Inline Memory Module), the single pin memory bar of this kind can equally insert in the slot with the expansion slot plug-in card, and two kinds of 30pin and 72pin are arranged usually; 3. double pin memory bar (DIMM, Dual Inline Memory Module), this kind is double pin memory bar, is the trend that designs at present, and two kinds of 144pin and 168pin are arranged usually.

DIMM type memory bar connector generally comprises a main body, and the main body two ends offer left and right earclip, and memory bar is fixed in the main body slot, and the effect of earclip is that memory bar is fixed, and prevents that memory bar from deviating from.At present, earclip is generally taked two kinds of versions: one is that plastics add spring-piece type, but this its elasticity of a kind of earclip is bad, installs behind the memory bar under the situation of vibrations, memory bar is deviate from from slot easily, and when frequently exchanging memory bar for, plastic wall is damaged easily; Its two, be the metal structure formula, this kind earclip good springiness, the fixed memory bar is firm, but the plane and the terminal flatness that exist leg are difficult to guarantee complex structure, Mould Machining difficulty, size is difficult to guarantee, earclip and main body are fixed pressured go into and be easy to generate defectives such as distortion, plating expense height.

Summary of the invention

At the existing defective of above-mentioned public technology, the utility model purpose is to provide a kind of SO-DIMM type memory bar connector, its good springiness, and fixed memory bar that can be firm, processing mold is simple, can effectively prevent the earclip distortion.

For realizing above goal of the invention, a kind of SO-DIMM type memory bar connector that the utility model provides, it comprises that mainly a body, left earclip, auris dextra button form, wherein, left and right earclip is assemblied in the left and right two ends of body respectively symmetrically.Be respectively equipped with the terminal groove that inserts for terminal in the both sides up and down of Connection Block body, at the parallel memory bar slot that offers of Connection Block body upside with terminal groove, on this memory bar slot left side, right two ends are equipped with an earclip slot that is used for fixing earclip, the structure of earclip comprises elastic plate, two parts of fixed head, elastic plate is provided with Elastic buckle and the spacing pressing plate that is used for fixing memory bar, have on the fixed head earclip is fixed on harpoon pin on the Connection Block body, described spacing pressing plate and Elastic buckle front end this harpoon pin direction relatively inwardly become an angle that slopes inwardly, in addition, also be provided with leg on the fixed head.

Embodiment

See also shown in Figure 1, be the whole perspective view of SO-DIMM type memory bar connector provided by the utility model, it mainly comprises a body 10, left earclip 20, auris dextra button 30 compositions, wherein, a left side earclip 20, auris dextra button 30 complete lattices are identical, are assemblied in the left and right two ends of body 10 respectively symmetrically.

See also shown in Figure 2, be the utility model SO-DIMM type memory bar connector body structure chart, upside at this Connection Block body 10 is provided with a plurality of terminal grooves 12, and at the downside of this Connection Block body 10, also be provided with terminal groove 13 (referring to shown in Figure 1) with the terminal groove 12 staggered positions of upside, terminal groove 12 and terminal groove 13 are all in order to ccontaining terminal.At Connection Block body 10 upsides and the terminal groove 12 parallel memory bar slots 14 that offer, certain position offers a positioning block 15 on this memory bar slot 14, this locating piece 15 is one to be circular-arc baffle plate, in addition, be equipped with an earclip slot 16 that is used for fixing earclip at described memory bar slot 14 left and right two ends.

See also shown in Figure 3, be the utility model SO-DIMM type memory bar connector earclip structure chart, because left earclip 20, auris dextra button 30 its structures are identical, at this is that example is illustrated with left earclip 20 only, as shown, left side earclip 20 adopts split-type structural, it mainly comprises elastic plate 210,220 two parts of fixed head, this elastic plate 210 is a stamping parts, the one end offers one and is bent into circular-arc Elastic buckle 211, offer a spacing pressing plate 212 in order to restriction memory bar position that is stamped to form in Elastic buckle 211 1 sides, this spacing pressing plate 212 has an inclined-plane that slopes inwardly 213, from up to down is pressed into when with convenience memory bar being installed; At elastic plate 210 other ends one harpoon pin 214 is arranged, be used for left earclip 20 is installed and fixed in the earclip slot 16 of Connection Block body 10, these harpoon pin 214 ends have two foots 217, and a bar shaped space is arranged between this two foot 217, thereby two foots 217 of harpoon pin 214 can inwardly compress; Above-mentioned spacing pressing plate 212 and Elastic buckle 211 front ends these harpoon pin 214 directions relatively inwardly have angle, and this angle angular range is preferable with 15 °～30 °; Be provided with a guide vane end stop 215 and a wedge 216 with the middle part of spacing pressing plate 212 relative sides on the elastic plate 210, separated by a distance between this guide vane end stop 215 and the wedge 216; Described fixed head 220 also is a stamping parts, and one of these fixed head 220 1 ends side has one upwards vertically to bend the leg 221 that forms, and the other end is an annular cover 223, and the edge has one vertically to bend the fixed card 222 that forms between this annular cover 223 and the leg 221.When said fixing plate 220 is combined on the elastic plate 210, elastic plate 210 is passed the annular cover 223 of fixed head 220 from harpoon pin 214 1 ends, fixed card 222 on the fixed head 220 is inserted in the guide vane end stop 215 and the gap between the wedge 216 of elastic plate 210, therefore, by of the qualification effect of this guide vane end stop 215 with wedge 216, just fixed head 220 can be installed on the elastic plate 210, other sees also shown in Figure 1, insert in the earclip slot 16 of Connection Block body 10 by harpoon pin 214, can should be fixedly installed on the Connection Block body 10 by left side earclip 20.

See also Fig. 2, shown in Figure 4, for the utility model inserts the memory bar structural representation, when using the utility model, under the guiding of Connection Block body 10 locating pieces 15, can be with memory bar 40 with about 20.Angle insert in the memory bar slot 14, again firmly with memory bar 40 past pressing down, this moment is because the effect on spacing pressing plate 212 inclined-planes 213, the left and right earclip in Connection Block body 10 both

sides

20,30 is stressed to be opened to both sides, when treating that Elastic buckle 211 embeds the groove of both sides on the memory bar 40, promptly finished the installation of memory bar 40.Fix memory bar 40 by left and

right earclip

20,30, can avoid deviating from because of concussion causes memory bar 40.If when needing dismounting memory bar 40, only need left and

right earclip

20,30 is outwards opened, the groove that Elastic buckle 211 is broken away from the memory bar 40 oppositely withdraws from memory bar 40 with suitable angle and gets final product.

In sum, the SO-DIMM type memory bar connector that the utility model provides, its earclip structural elasticity is good, fixed memory bar that can be firm, the processing mold of Connection Block body is simple, can effectively prevent the earclip distortion.
