Description
Technical field
The utility model relates to the memory bar connector, especially the terminal structure of the connector of the double pin memory bar of small size (SO-DIMM, Small Outline Dual Inline Memory Module) 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 bars (DIMM, Dual Inline Memory Module), the double pin memory bar of this kind is the trend that designs at present, and two kinds of 144pin and 168pin are arranged usually.
In recent years, along with the requirement of high density assembling, develop the direct type connector of various low insertion forces.But,, in grafting or unloading process, very easily lose if this connector does not have enough intensity; And present many DIMM type memory bar connectors, disclosed as No. the 316721st, Taiwan patent announcement, the terminal deformed region of this utility model is little, poor flexibility, cause the fracture of elasticity position easily, after memory bar inserted, stationarity was bad, be easy to generate fit clearance, the especially long-term back terminal that uses does not reset; Or, cause the terminal distortion because of by force memory bar being inserted, and influence the contact of terminal, easily cause the signal transmission not good.In addition, the plastic body complex structure of Pei Heing with it, mould molding difficulty.
Summary of the invention
The utility model is in view of the shortcoming that exists in the above-mentioned known technology, the double pin memory bar of a kind of small size (SO-DIMM is provided, Small Outline Dual Inline Memory Module) connector terminal structure, this terminal good springiness, memory bar good fixing effect, contact portion transition slyness, the elasticity position is difficult for fracture, and the terminal stability under loading is even, and is not yielding, contact is good, and the plastic body of Pei Heing is simple in structure with it.
For realizing above goal of the invention, the utility model provides a kind of SO-DIMM type memory bar connector the first terminal and second terminal, these terminals all mainly comprise four parts such as pressure side portion, fastener, leg, elastic portion and contact site, the first terminal, second terminal insert respectively in the first terminal groove, second terminal groove, pressure side portion respectively is provided with an elastic portion by a side of memory bar slot on the first terminal and second terminal, wherein, the elastic portion of the first terminal is " U " shape structure, and the elastic portion of second terminal is " L " shape; One end of above-mentioned the first terminal, the second terminal elastic portion is the contact site that stretches in the memory bar slot, and the other end relative with elastic portion is equipped with leg, and is equipped with the fastener that is used for terminal is fastened on terminal groove at the middle part.
Description of drawings
Below in conjunction with accompanying drawing the utility model SO-DIMM type memory bar connector terminal structure is described in further detail.
Fig. 1 is the enforcement schematic diagram of terminal among the utility model embodiment;
Fig. 2 is the enforcement schematic diagram of terminal among the utility model embodiment;
Fig. 3 is the structural representation of the first terminal among the utility model embodiment;
Fig. 4 is the structural representation of second terminal among the utility model embodiment;
Fig. 5 is the profile that the first terminal cooperates with plastic body among the utility model embodiment;
Fig. 6 is the profile that second terminal cooperates with plastic body among the utility model embodiment.
Embodiment
See also Fig. 1, shown in Figure 2, enforcement schematic diagram for terminal among the utility model embodiment, upside at Connection Block body 10 is provided with a plurality of the first terminal grooves 12, and at the downside of this Connection Block body 10, be provided with second terminal groove 13 with the first terminal groove 12 staggered positions of upside, the first terminal groove 12 and second terminal groove 13 are respectively in order to ccontaining the first terminal 20, second terminal 30.
See also Fig. 3, shown in Figure 4, it is the structural representation of the utility model terminal, the first terminal 20, second terminal 30 includes pressure side portion, fastener, leg, elastic portion and contact site, as shown, pressure side portion 21 on the first terminal 20 and second terminal 30,31 ends by memory bar slot 14 (referring to shown in Figure 2) are equipped with the elastic portion 22 of a longer structure, 32, therefore, elastic arm can extend, guarantee enough elasticity, wherein, for cooperating the shape (not icon) of the known Connection Block body the first terminal groove 12 and second terminal groove 13, the elastic portion 22 of the first terminal 20 is " U " shape structure, and the elastic portion 32 of second terminal 30 is " L " shape structure, in this elastic portion 22,32 ends offer contact site 23,33, this contact jaw 23,33 slightly outwardly-bent protrusions, and its curved surface rounding off; Be equipped with leg 25,35 in pressure side portion 21,31 with the other end of elastic portion 22,32 relative sides, and be equipped with the first terminal 20 and second terminal 30 are fixed on fastener 24,34 in the Connection Block body 10 upper end pilot trench at the middle part of pressure side portion 21,31 and elastic portion 22,32 homonymies, offer at least one stuck point 241,341 on this fastener 24,34, this stuck point 241,341 is convenient to fixed terminal 20,30.
Further consult Fig. 5, shown in Figure 6, when the first terminal 20, second terminal 30 is respectively charged into the first terminal groove 12, second terminal groove 13, its contact site 23,33 will be emerging in the memory bar slot 14, and the stuck point 241,341 on the fastener 24,34 is fastened on respectively in the first terminal groove 12, second terminal groove 13 closely, the first terminal 20, the second terminals 30 are separately fixed in the first terminal groove 12 and second terminal groove 13.When contact site 23,33 was subjected to the pressure of memory bar, the first terminal 20 and second terminal 30 can produce strain accordingly, because elastic portion 22,32 is longer, and resilient arm structure transition slyness, therefore deformed region increases, and terminal is more not fragile, has increased the useful life of terminal.The first terminal 20 and second terminal 30 are interconnected, make that resistance was little when memory bar inserted, and have good contact effect.
In sum, terminal structure provided by the utility model is reasonable, good springiness, and the fixed memory bar is effective, contact portion transition slyness, the elasticity position is difficult for fracture, and the terminal stability under loading is even, not yielding, contact is good, and the plastic body of Pei Heing is simple in structure with it.
