Description

A kind of elastic hole

Technical field

The utility model belongs to the connector technique field, especially relates 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 complexity, 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, there is a segment distance in Jie Chu zone from end face simultaneously, and its application scenario in high density, multicore number, short space is restricted.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of elastic hole at above-mentioned deficiency of the prior art, 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 solution adopted in the utility model is: a kind of elastic hole, it is characterized in that: form by receptacle body and sheath three parts that are arranged on the spring coil of receptacle body inside and are sleeved on the receptacle body upper end outside, described spring coil is positioned at receptacle body top, described spring coil is intervolved by many elastic arm bendings and forms, described spring coil top is crotch shape fixed position, described crotch shape fixed position hangs over the end face of receptacle body, described crotch shape fixed position forms fixed pivot between receptacle body and sheath and with receptacle body and sheath, described spring coil bottom is the circular arc contact site, and described spring coil bottom is structure as a whole.

Above-mentioned a kind of elastic hole is characterized in that: described 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 described sheath and the receptacle body is crimping.

The utility model compared with prior art has the following advantages:

1, simple in structure, reasonable in design, this elastic hole is made up of receptacle body and the sheath that is arranged on the spring coil of receptacle body inside and is sleeved on the receptacle body upper end outside, spring coil is intervolved by many elastic arm bendings and forms, 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 utility model is at 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 contact system in parallel, 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.

Below by drawings and Examples, the utility model is described in further detail.

Embodiment

A kind of elastic hole as illustrated in fig. 1 and 2, form by receptacle body 3 and sheath 1 three parts that are arranged on the spring coil 2 of receptacle body 3 inside and are sleeved on the outside, receptacle body 3 upper ends, described spring coil 2 is positioned at receptacle body 3 tops, described spring coil 2 is intervolved by many elastic arm bendings and forms, described spring coil 2 tops are crotch shape fixed position, described crotch shape fixed position hangs over the end face of receptacle body 3, described crotch shape fixed position forms fixed pivot between receptacle body 3 and sheath 1 and with receptacle body 3 and sheath 1, described spring coil 2 bottoms are the circular arc contact site, and described spring coil 2 bottoms are structure as a whole.

As shown in Figure 3, described many elastic arms are forming a gorge circle 4 in the radial direction.

Connected mode between described sheath 1 and the receptacle body 3 is crimping.

In the utility model, 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 forms final part after gold-plated.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 plug together, after every elastic arm of spring coil 2 is subjected to the contact pin extruding, the one end of spring coil 2 then slides along the inwall of receptacle body 3, form the sliding fulcrum of simply supported beam, contact pin owing to be the envelope contact of many elastic arms, is formed fair surplus contact system in parallel in the segment length zone at gorge circle position Elastic Contact, 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, the utility model is at existing wire spring socket and hat spring socket deficiency, 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 contact system in parallel, 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 utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection range of technical solutions of the utility model according to the utility model technical spirit.
