Description
Art
The invention belongs to electric connector contact, particularly a kind of sleave contact pin.
Background technology
Current existing reliability, the good electric connector contact of stability have wire spring socket, split groove jack, twisted wire contact pin, hat spring socket, spring needle etc., their common feature is applicable to the lower signal of transmission frequency, and when transmission very high-frequency signal, because the structure of the propagation characteristic of high-frequency signal and above contact, material limit, signal is propagated on the surface of part, add signal path lengths, cause distorted signals and loss sharply to increase; The contact length of above contact is longer simultaneously, and the electric connector volume be made up of it is large, docks highly very high, has been not suitable with the application demand that electronic equipment components and parts are day by day intensive, cabinet reduces day by day; And the terminations that above contact adopts is generally the fixed forms such as crimping, welding, solderless wrapped connection, screw connection, the installation of equipment, debugging, maintenance are very inconvenient.
Summary of the invention
The object of this invention is to provide that a kind of processing technology is simple, overall dimensions are little, the contact contact pin contacting piece that closely reliable, long service life, superior performance, installation and maintenance are easy: a kind of sleave contact pin, to make up the shortcoming and defect of Conventional contact part, be applicable to the transmission of low frequency and high-frequency signal.
The object of the present invention is achieved like this: after wire random coil, namely forms the contact pin of cylindricality after shaping, shaping, setting, is exactly sleave contact pin.To be filled by wire random coil because this sleave contact pin is overall and form, the effect that the result of this random coil causes some ideal, as: 1, break signal in the inner mutual induction impact of contact, be applicable to very much the transmission of high-frequency signal; 2, reduce the skin effect of signal transmitting path length and high-frequency signal, be applicable to very much the transmission of small-signal; 3, improve globality and the intensity of sleave contact pin; 4, sleave contact pin inside creates multiple signal path, and form " redundancy " transmission, reliability is higher; 5, signal is by shortest path, decreases distortion, resistance and inductance, is conducive to the transmission of high-frequency signal; What 6, the volume of sleave contact pin can do is very little.7, the elasticity that the elasticity that sleave contact pin has can realize solderless connects.
A kind of feature of sleave contact pin is it is that wire by random coil is formed, in a cylindrical body.
The present invention compared with prior art has following advantage and good effect: the signaling rate that (1) is high, makes the frequency of signal higher than 20GHz's; (2) the elastic compression formula interconnection of crimping need not be welded; (3) low setting height(from bottom), can be applicable to the perpendicular interconnection between grid array (LGA) integrated circuit socket and PCB and PCB; (4) problem of PCB plate through hole and surperficial Erection Welding Technology is solved.(5) solderless connects, and is convenient to install, upgrade and system maintenance; (6) connecting number of contacts can from 1 to 7000; (7) the little contactinterval to 1mm or larger.
A kind of sleave contact pin can provide the interconnection solution of the various flexibility and reliability of needs, can be used for connect almost any metal surface to metal surface, low flat and compact intraconnection can be realized in pcb board,, high speed signal high in reliability, little space, high density, extreme environmental condition all must meet, it is desirable interconnection solution.

Embodiment
Fig. 1 is a kind of structural representation of sleave contact pin, and sleave contact pin is by after wire 1 random coil, in cylindricality after shaping, shaping, setting, is sleave contact pin.To be filled by wire random coil because this sleave contact pin is overall and form, the effect that the result of this random coil causes some ideal, be more beneficial to the transmission of high-frequency signal, and volume is less, contact is more reliable.
Fig. 2 Fig. 3 is that application sleave contact pin realizes schematic diagram connected vertically between printed board and printed board, and installing and using of sleave contact pin is very simple, and without the need to welding or crimping, general only needs is undertaken by following three steps.First, sleave contact pin 2 is installed in the fixing hole on insulation fixing plate 3, the two ends of sleave contact pin 2 are given prominence in the both sides of insulated mounting plate 3.Fixing hole on insulated mounting plate 3 processes according to the position correspondence of the metal pad 5 connected required in upper and lower printed board 4; Then, alignment, aligns sleave contact pin 3 with the metal pad 5 be connected required in upper and lower printed board 4; Finally, compress, upper and lower printed board 4 and insulated mounting plate 3 are compressed and be fixed together, and sleave contact pin 2 is compressed and the elasticity of dependence own tightly withstands on metal pad 5, the corresponding metal pad of upper and lower printed board 4 is connected 5 and is connected together, just so simple.
A kind of sleave contact pin can be used for connecting almost any metal surface (pad) to pad.It is desirable interconnection solution, works under can meeting the working conditions such as reliability is high, high speed signal, little space, high density, extreme environmental condition.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every above embodiment is done according to the technology of the present invention essence any simple modification, change and equivalent structure change, all still belong in the protection range of technical solution of the present invention.
The present invention compared with prior art has following advantage and good effect: formed by the filling of wire random coil because this sleave contact pin is overall, the effect that the result of this random coil causes some ideal, more be beneficial to the transmission of high-frequency signal, and volume is less, contact is more reliable, can be used for connecting almost any metal surface (pad) to pad.There is following characteristics: the signaling rate that (1) is high, make the frequency of signal higher than 20GHz's; (2) the compression interconnection of crimping need not be welded; (3) low setting height(from bottom), can be applicable to the perpendicular interconnection between grid array (LGA) integrated circuit socket and PCB and PCB; (4) problem of PCB plate through hole and surperficial Erection Welding Technology is solved.(5) solderless connects, and is convenient to install, upgrade and system maintenance; (6) connecting number of contacts can from 1 to 7000; (7) the little contactinterval to 1mm or larger.
