Abstract
The invention discloses an elastic jack, which comprises a jack body, a spring coil and a protective sleeve, wherein the spring coil is disposed inside the jack body, and the protective sleeve is sleeved outside the upper end of the jack body. The spring coil is disposed on the upper portion of the jack body and formed by coiling a plurality of elastic arms, the upper portion of the spring coil is a hooked fixed portion hung on the end face of the jack body, the hooked fixed portion is positioned between the jack body and the protective sleeve, the hooked fixed portion, the jack body and the protective form a fixed fulcrum, and the lower portion of the spring coil is an arc contact portion in an integrated structure. The elastic jack is simple in structure, reasonable in design and high in current carrying capacity, requires low plugging force and can adapt to low spaces.
Description
Technical field
The invention belongs to the connector technique field, especially relate to a kind of elastic hole.
Background technology
The contact numerous types of connector, commonly used have cylindrical shape contact, stranded elastic contact pin contact, wire spring socket contact, hat spring socket contact and a square contact.In these contacts, wire spring socket contact and stranded elastic contact pin contact have higher reliability and low contact engaging and separating force.The version of hat spring socket contact is then identical with the wire spring socket contact with mechanical model; And when keeping advantage; Avoided wire spring socket contact piece structure complicacy, fracture of wire, anti-probe damage ability is low, ampacity is little and tenaculum hot-line insertion and extraction problems such as (plug and play) not; But the contact engaging and separating force of hat spring socket contact is big than the wire spring socket contact, and there is a segment distance in the zone of contact from end face simultaneously, and its application scenario in high density, multicore number, short space is restricted.
Summary of the invention
Technical problem to be solved by this invention is to above-mentioned deficiency of the prior art a kind of elastic hole to be provided, and it is simple in structure, reasonable in design and ampacity is big, and contact engaging and separating force is low simultaneously, can adapt to short space.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of elastic hole is characterized in that: by receptacle body and be arranged on the inner spring coil of receptacle body and form with sheath three parts that are sleeved on the outside, receptacle body upper end, said spring coil is positioned at receptacle body top; Said spring coil is rolled up and is formed by many elastic arms are crooked; Said spring coil top is crotch shape fixed position, and said crotch shape fixed position hangs over the end face of receptacle body, and said crotch shape fixed position forms fixed pivot between receptacle body and sheath and with receptacle body and sheath; Said spring coil bottom is the circular arc contact site, and said spring coil bottom is structure as a whole.
Above-mentioned a kind of elastic hole is characterized in that: said many elastic arms are forming a gorge circle in the radial direction.
Above-mentioned a kind of elastic hole is characterized in that: the connected mode between said sheath and the receptacle body is crimping.
The present invention compared with prior art has the following advantages:
1, simple in structure, reasonable in design; This elastic hole is by receptacle body and be arranged on the inner spring coil of receptacle body and form with the sheath that is sleeved on the outside, receptacle body upper end, and spring coil is rolled up and formed by many elastic arms are crooked, and spring coil top is crotch shape fixed position; Crotch shape fixed position hangs over the end face of receptacle body; Crotch shape fixed position forms fixed pivot between receptacle body and sheath and with receptacle body and sheath, the spring coil bottom is the circular arc contact site, and the spring coil bottom is structure as a whole.
2, The present invention be directed to existing wire spring socket and hat spring socket deficiency; Adopt an end bifurcated to fix; The structure that the other end is connected as a single entity and slides constitutes the simply supported beam mechanical model of standard and forms fair surplus parallelly connected contact system, obtains being electrically connected of highly reliable, low connect-disconnect force.
3, have characteristics simple in structure, that contact engaging and separating force is low and ampacity is big simultaneously, can adapt to short space.
Through accompanying drawing and embodiment, the present invention is done further detailed description below.

Embodiment
A kind of elastic hole as illustrated in fig. 1 and 2; By receptacle body 3 and be arranged on the inner spring coils of receptacle body 32 and form with sheath 1 three parts that are sleeved on the outside, receptacle body 3 upper ends; Said spring coil 2 is positioned at receptacle body 3 tops, and said spring coil 2 is rolled up and formed by many elastic arms are crooked, and said spring coil 2 tops are crotch shape fixed position; Said crotch shape fixed position hangs over the end face of receptacle body 3; Said crotch shape fixed position forms fixed pivot between receptacle body 3 and sheath 1 and with receptacle body 3 and sheath 1, said spring coil 2 bottoms are the circular arc contact site, and said spring coil 2 bottoms are structure as a whole.
As shown in Figure 3, said many elastic arms are forming a gorge circle 4 in the radial direction.
Connected mode between said sheath 1 and the receptacle body 3 is crimping.
Among the present invention, spring coil 2 is the core part of elastic hole, and it becomes expansion shape shown in Figure 2 by the beryllium bronze band blanking, and each bifurcated just forms an elastic arm, the Elastic Contact effect of realization and contact pin.Blanking is after crooked and volume circle forms circular arc contact site and crotch shape fixed position, and crotch shape fixed position hangs over the end face of receptacle body 3, and is fixed by sheath 1, forms fixed pivot.The other end of spring coil 2 is the structure that fuses, and can guarantee the consistency of every resilient-arm position size.In addition, in order to obtain higher consistency and elasticity, spring coil 2 has carried out heat treatment after brake forming, and after gold-plated, forms final part.Many elastic arms of spring coil 2, the inscribed circle of radial direction formation in receptacle body 3 equally is called gorge circle 4 with the ordinary lines spring socket.When contact pin and elastic hole plugged together, after every elastic arm of spring coil 2 received the contact pin extruding, the one end of spring coil 2 then slided along the inwall of receptacle body 3; Form the sliding fulcrum of simply supported beam; Contact pin is Elastic Contact in the segment length zone at gorge circle position, owing to be the envelope contact of many elastic arms, forms fair surplus parallelly connected contact system; Adopt elastomeric beryllium bronze band to form simply supported beam mechanical model structure simultaneously, can obtain being electrically connected of highly reliable, low connect-disconnect force.
In sum; It is not enough with the hat spring socket to The present invention be directed to existing wire spring socket, adopts an end bifurcated to fix the structure that the other end is connected as a single entity and slides; The simply supported beam mechanical model of formation standard is also formed fair surplus parallelly connected contact system, obtains being electrically connected of highly reliable, low connect-disconnect force.Therefore, have characteristics simple in structure, that contact engaging and separating force is low and ampacity is big.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any restriction, every technical spirit changes any simple modification, change and the equivalent structure that above embodiment did according to the present invention, all still belongs in the protection range of technical scheme of the present invention.
