Abstract
An elastic contact-pin contact part is composed of a reed contact ring and a contact pin lead foot, wherein the reed contact ring is in a waist drum shape, the middle is protruded outwards, two ends of the contact pin lead foot are respectively provided with a step, a limiting groove is formed between the two steps, and the reed contact ring is sleeved inside the limiting groove between the steps of the contact pin lead foot. The elastic contact-pin contact part is soft to pull and insert, high in strength, capable of being independently used without protection, and wide in application range.
Description
Technical field
The present invention relates to a kind of contact, relate in particular to a kind of highly reliable high strength low connect-disconnect force contact pin contacting piece.
Background technology
At present a large amount of contact kinds of using are more, and usage comparison has the combination of rigidity contact pin and elastic hole (notching construction, line spring hole) and the combination of rigidity jack and elastic contact pin (twist needle) widely.The contact of these several modes respectively has merits and demerits: fluting jack contact contact engaging and separating force is larger, generally need design pillar protection jack; Although line spring hole has smaller and stable separating force, its intensity is not high, and pillar protection must will be designed in the outside, and line spring hole is subjected to process technology limit not do too littlely, usually just is difficult to realize below 20#; The twist needle contact strength is not high enough, can not use separately (instigating the used time to coat protection by insulator), and is same, is subjected to process technology limit twist needle structure contact also can not process too greatly.
Summary of the invention
Patent of the present invention aims to provide a kind of elastic contact pin contact of highly reliable high strength low connect-disconnect force, makes it both to have flexibility and the Multi-contact characteristic of twist needle contact, also has the intensity of rigidity contact pin, can independently use, and the facility that do not need protection.
The present invention adopts following technical scheme:
Described contact is comprised of reed contact ring and contact pin pin, described reed contact ring is dolioform, the mid portion evagination, and described contact pin pin two ends are respectively equipped with step, form stopper slot between two steps, the reed contact ring is set in stopper slot between described contact pin pin two steps.
Described reed contact ring is fixedly connected with contact pin pin one end step, and the other end is free to slide along contact pin pin stopper slot.
Elastic contact pin contact of the present invention has following features:
1) but Multi-contact, contact resistance is little and stable, is suitable for the transmission of low level small-signal;
2) plug is soft:
3) be suitable for making the contact of different size number.
4) can be applicable to the leads ends of straight cutting printed board connector, as the soldering-free type contact form, need not when contacting with printed board pin is realized electrical connection with soldering of printed boards, quick detachable.
Description of drawings
Fig. 1 is reed-type contact ring cutaway view in elastic contact pin contact of the present invention.
Fig. 2 is elastic contact pin contact piece structure schematic diagram of the present invention.
In figure: 1-reed contact ring, 2-contact pin pin, 2a, 2b-step.
Embodiment
As shown in the figure, elastic contact pin contact of the present invention is made of reed-type contact ring 1 and contact pin pin 2, described reed contact ring 1 is dolioform, the mid portion evagination, described contact pin pin 2 two ends are respectively equipped with step 2a, 2b, between form stopper slot, reed contact ring 1 is placed in stopper slot between this contact pin pin 2 two ends step 2a, 2b.Reed contact ring 1 can be fixedly connected with by modes such as welding or crimping with the step of contact pin pin 2 one ends, the other end is unfixing, and an end of contact ring 1 can be free to slide along contact pin pin 2 stopper slots yet.For increasing the elasticity of reed contact ring 1, its border also evenly is provided with axial mounting hole in addition.The step 2b of contact pin pin 2 butt ends can be made into semicircular structure, is convenient to dock with jack contact, patches power little.Described reed contact ring is by beryllium-bronze material manufacturing and gold-plated through heat treatment.
Reed-type contact ring 1 connects as one with contact pin pin 2 tail end step 2a, and it is not fixing with contact pin pin 2 butt end step 2b, can be free to slide, namely form the mechanical model of simply supported beam, can obtain when coordinating with jack contact to electrically contact reliably and separating force that facet is stable.
When elastic contact pin contact of the present invention plugs together, with the effect of butt end jack contact endoporus under, contact ring produces elastic force to internal strain, under the elastic force effect, with the Socket bore Multi-contact, reliability is higher; Contact ring one end is fixed, and the other end can be free to slide, and is conducive to its distortion, makes contact engaging and separating force less;
Simultaneously the inner metal ferrule pin that adopts of contact ring is fixed, and makes whole contact pin contacting piece intensity higher, can use separately and need not protect, and is applied widely.
