Description
technical fieldthe invention belongs to technical field of electric connectors, be specifically related to a kind of Wire spring type electric coupling device being applicable to 1.27mm spacing.
background technologyin prior art, to have contact engaging and separating force little for the wire spring socket of connector, the feature that contact resistance is little, when contact pin inserts jack, these elastic metallic yarns are wrapped in around contact pin respectively tightly, form line contact, can reach a pair pin hole is equivalent to several to common pin, the effect that hole parallel connection uses, there is contact resistance low and stable, contact engaging and separating force is little, the advantage that contact wearing and tearing are low and connect-disconnect life is long, and the ability of anti-powerful vibratory impulse is strong, function due to connector normally plays the mechanical performance and electric property that depend on connector, and electromagnetic wave, vibrations etc. can cause detrimental effects to the mechanical performance of connector and electric property, therefore, to the connector worked in the presence of a harsh environment, good anti electromagnetic wave and the performance of against shock need be had, although the connector anti-vibrating and impact power of prior art is strong, but be easily subject to electromagnetic interference, affect the stability of connector, and the structure in line spring hole adopts metal material completely, the making course of processing is loaded down with trivial details, cost is high and volume is large, line spring hole cannot normally use in the connector of 1.27mm and following spacing in grafting,
summary of the inventionthe object of the invention is to solve that prior art exists anti-electromagnetic interference capability difference, stability is low, cost is high and cannot be suitable for the technical problem of 1.27mm interval connector, there is provided a kind of Wire spring type electric coupling device being applicable to 1.27mm spacing, to overcome the deficiencies in the prior art.
To achieve these goals, a kind of Wire spring type electric coupling device being applicable to 1.27mm spacing of the present invention, its main points are that it comprises metal screen case; The two ends place of described metal screen case inwall is respectively equipped with locating ring and fixed card slot; The insulated mounting plate of outer wall belt boss is provided with in described metal screen case; Boss on described insulated mounting plate and the locating ring in metal screen case are mutual correspondingly to be connected and fixed; Described insulated mounting plate is provided with the location hole in clamping line spring hole; The rear portion in described line spring hole, inside and front portion are respectively equipped with insulating sleeve, inner sleeve and pressure welding case; Put solderless wrapped connection in inside, described line spring hole and have beryllium-bronze silk; Described one end is provided with fluid sealant with in the metal screen case of fixed card slot; Described fluid sealant is sealedly and fixedly connected with metal screen case mutually by snapping onto in fixed card slot.
The present invention is rational in infrastructure, novel in design, because rear end, line spring hole adopts insulating sleeve, can not produce because using that the making course of processing that causes of metal material is loaded down with trivial details, production cost is high and bulky defect, and go for the connector of 1.27mm and following spacing; Meanwhile, Metal shielding shell can effectively block electromagnetic disturb, and improves stability and the reliability of connector.The invention solves that prior art anti-electromagnetic interference capability is poor, stability is low, cost is high and the technical problem of 1.27mm interval connector cannot be suitable for.
accompanying drawing explanationfig. 1 is structural representation front sectional view of the present invention;
Fig. 2 is that the present invention disassembles status architecture schematic diagram;
Fig. 3 is line spring pore structure of the present invention signal partial sectional view.
In figure 1, metal screen case 2, insulated mounting plate 3, line spring hole 4, fluid sealant 5, locating ring 6, fixed card slot 7, boss 8, location hole 9, insulating sleeve 10, beryllium-bronze silk 11, inner sleeve 12, pressure welding case
embodimentwith reference to Fig. 1, Fig. 2 and Fig. 3, the present invention it comprise metal screen case 1; The two ends place of described metal screen case 1 inwall is respectively equipped with locating ring 5 and fixed card slot 6; The insulated mounting plate 2 of outer wall belt boss 7 is provided with in described metal screen case 1; Boss 7 on described insulated mounting plate 2 connects and fixes with the locating ring 5 in metal screen case 1 is mutually corresponding; Described insulated mounting plate 2 is provided with the location hole 8 in the wired spring hole 3 of clamping; The rear portion in described line spring hole 3, inside and front portion are respectively equipped with insulating sleeve 9, inner sleeve 11 and pressure welding case 12; In the inner sleeve 11 of inside, described line spring hole 3, solderless wrapped connection has beryllium-bronze silk 10; Described one end is provided with fluid sealant 4 with in the metal screen case 1 of fixed card slot 6; Described fluid sealant 4 is sealedly and fixedly connected with metal screen case 1 mutually by snapping onto in fixed card slot 6.
Line spring hole 3 of the present invention, owing to have employed insulating sleeve, decreases the volume in line spring hole, makes line spring hole 3 protheca outer wall be less than the inwall of insulated mounting plate 2 location hole 8, can normal mounting on the electric connector of 1.27mm spacing; Owing to adopting line spring hole technology, when contact pin inserts jack, these elastic metallic yarns are wrapped in around contact pin respectively tightly, form line contact, and a pair pin hole is equivalent to several to common pin, hole parallel connection use, drastically increases the reliability of contact.
The present invention adopts metal screen case, greatly improve pitch electrical connector reliability between 1.27mm, this line spring hole uses insulating sleeve to carry out substituted metal sleeve pipe, greatly reduce the size in line spring hole, achieve the application of line spring hole between 1.27mm on pitch electrical connector, overcome the deficiencies in the prior art, owing to adopting Metal shielding shell, effectively can shield various electromagnetic interference, improve the reliability of connector.
Structure of the present invention is simple, reasonable in design, and fault-tolerant ability is strong, with low cost, applied widely, result of use is good.
