Abstract
The utility model provides an arch-shaped supporting elastic contactor. The utility model forms a cylinder shape. A side wall louvre window grid is bowed inwards. The utility model is made of louvre window strips bowed by metal strip lack window grids with high elasticity in resegmentation and enclosure way. The utility model is used for the contact part of a female contactor of electric connection device. The utility model has the advantages of small contact resistor, wide use temperature range, and predominant vibration resistance and impact resistance performance. The utility model can enhance the contact reliability and service life of the electric connection device. Because contact surfaces are smooth, the contact for insertion and separation saves labor. The utility model is especially suitable for the design of the electric connection device with multiple wire quantities and high density.
Description
The utility model relates to a kind of arch support resilient contact that is used for electric connector female contact contact portion.
Electric connector is to use the very wide a kind of electronic component in field, its core is right by contacting of forming of male contact and female contact, its function just by contacting of forming by male contact and female contact to effectively, contact reliably finishes, and the height key of the quality of its quality, reliability is to contact right female contact.In the prior art, traditional, the most representative electric connector is the electric connector of " integrated cantilever beam pressure-type ", its structure as shown in Figure 1, female contact is generally formed by phosphor bronze wire rod car system, one end is terminals, the other end is the Elastic Contact end that the cantilever beam of symmetry constitutes, each cantilever beam is all from the lean-in Dou of root, the female contact of this form: 1, electrical-contact area little (some contact), contact surface coarse (limited by processing method), the attached protective layer of contact surface plating be easy to contact to plug together with separating process in wear and tear, metallic matrix is exposed in the air and produces surface oxide layer, thereby contact resistance is bigger, contact is to easily generating heat when working, and contact will cause the cantilever beam root to be heated to heating when working, prestressing force is loose, causes the decay of cantilever beam to male contact pressure, and contact resistance further increases, contact is to the heating aggravation, and the result is the inefficacy that electrically contacts that makes electric connector; 2, the single-ended support of cantilever beam, when being subjected to mechanical oscillation and impact, its head end, promptly will produce pure oscillation with the male contact contact point, the moment disengaging contacts with male contact, and cantilever beam is long more, and the amplitude of generation is also just big more, moment breaks away from the time of contact of male contact also just long more, and reliability is not high; 3, because contact surface is coarse, contact and right plug together and separate effort, this makes it not be suitable for very much multi-thread number, highdensity electric connector designs.
The purpose of this utility model is to provide that a kind of contact area is big, contact surface is smooth and the shock proof arch support resilient contact of anti-vibration, and is used for electric connector female contact contact portion.
The purpose of this utility model can realize by such technical scheme: this contact area is big, contact surface is smooth and the shock proof arch support resilient contact of anti-vibration, it is cylindric, its sidewall louver window bar inwardly bends, be to prepare blind window band that window bar arches, cut apart, enclose circle again and make, can be fastened on the female contact base seat by metallic sheath and use with the high resiliency sheet metal strip; Also can directly pack in the circular hole of female contact matrix front end, use by interference fit is fixing.
This arch support resilient contact provided by the utility model, be used for electric connector female contact contact portion, can overcome that existing " integrated cantilever beam pressure-type " electric connector exists because electrical-contact area is little and the coarse contact resistance that causes of contact surface is big, contact the drawback that cantilever beam root prestressing force is loose, cantilever beam is decayed to male contact pressure that commute generates heat and causes because of heating, contact resistance is little, serviceability temperature wide ranges, long service life; Also overcome simultaneously existing " integrated cantilever beam pressure-type " and will cause the drawback that electrically contacts the moment disconnection when electric connector is vibrated and impacts, had remarkable anti-vibration shock resistance, can improve the contact reliability of electric connector widely; Also because contact surface is smooth, contact is to plugging together and separating laborsavingly, and the spy is applicable to the design of multi-thread number, highdensity electric connector.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail:
Fig. 1 is the structural representation of existing " integrated cantilever beam pressure-type " electric connector.
The schematic diagram of the arch support resilient contact that Fig. 2 is provided for the utility model embodiment.
Fig. 3 is fastened on the schematic diagram that uses on the female contact base seat for the arch support resilient contact that the utility model embodiment is provided by metallic sheath.
The arch support resilient contact that Fig. 4 is provided for the utility model embodiment fixing schematic diagram that uses in the circular hole of female contact matrix front end of directly packing into.
With reference to accompanying drawing 2,3,4, this contact area that the utility model embodiment is provided is big, contact surface is smooth, serviceability temperature wider range and the shock proof arch support resilient contact of anti-vibration, it is cylindric, its sidewall louver window bar 1 inwardly bends, and is to prepare blind window band that window bar arches, cut apart, enclose circle again and make with the high elastic modulus alloy band.
With reference to accompanying drawing 3, this arch support resilient contact that the utility model embodiment is provided can be fastened on the female contact base seat 4 by stainless steel sheath 2 and use.
With reference to accompanying drawing 4, this arch support resilient contact that the utility model embodiment is provided can directly be packed in the circular hole of female contact matrix 5 front ends, be used by interference fit is fixing.
Among the figure, the 3--male contact.
