Abstract
The utility model relates to a contact for connectors, which comprises a contact pin and a jack, wherein, the jack comprises an elastic circular pipe 1 and a rigid protective sleeve 2 which can be sheathed outside the circular pipe 1, one end of the elastic circular pipe 1 is provided with a plurality of axial notches, and an opening end of the circular pipe 1 is uniformly folded outward to form a bell opening shape; when the separation distance between the circular tube 1 and the protective sleeve 2 enables the contact pin to be inserted into an inner hole of the circular pipe 1 with slots, the joint of the contact pin and the inner hole wall of the circular pipe 1 and the joint of the outer part of the circular pipe 1 and the inner wall of the protective sleeve 2 are tight. Because of the special structural design of the jack of the contact, the contact pin and the jack can be conveniently plugged and pulled, the reliability of the electrical contact can be enhanced, and the long plugging and pulling lifetime and the reliable contact under the harsh environment can be ensured.
Description
The utility model relates to electric connector field, more particularly, relates to a kind of architecture advances that is easy to plug and can under any circumstance guarantees the connector contact that reliably electrically contacts.
Existing electric connector, its contact part contact pin jack connected modes that adopt more, contact pin is generally the cylinder that brass is made, jack is the elastic circular duct shape, have some straight troughs vertically, to axle center " closing in ", the back internal diameter that closes up is less than the inserting pin diameter in the contact pin insertion end, when contact pin inserts and the jack realization electrically contact.Generally make with the good bronze of elasticity, there is good conductor coating (as silver-plated, gold-plated etc.) on the surface, and the deficiency of this structure is that insertion force makes the overlay coating of contact pin be easy to wearing and tearing more greatly, even the wearing and tearing parent metal, along with the plug number of times increases, electrical contact performance will descend thereupon; On the other hand, in the connector course of work, particularly using is having vibration source, as in the operational environments such as vehicle in travelling, contact pin is subject to external influence and reduces electrical contact reliability and useful life with contacting of jack.
The purpose of this utility model is to provide a kind of contact that is used for electric connector, the contact of this electric connector can overcome the shortcoming of prior art, be convenient to the insertion between contact pin and jack and extract, simultaneously, thereby have when guaranteeing to insert contact than the long-pending contact resistance that reduces of large contact surface, on the other hand, this connector makes because of external vibration or applies external force the influence that contact pin jack electrically contacts is dropped to minimum level in installation and use.
The purpose of this utility model is to realize like this; construct a kind of contact that is used for connector and comprise contact pin part and receptacle portion; receptacle portion comprises that an end has the elastic circular duct 1 of a plurality of axial notch and rigid protective that one can be enclosed within this pipe 1 outside cover 2; described pipe 1 has an end of notch and evenly outwards digs into bell mouth shape; after one end of protective sleeve 2 is fixedly attached to the other end of pipe 1 opening; its other end can cover the loudspeaker opening that pipe 1 is outwards dug; maximum outside diameter and protective sleeve cooperation place internal diameter that pipe is outwards dug part can be interference fit; also can matched in clearance; when the endoporus of pipe 1 of protective sleeve is housed on cylinder type contact pin or conical contact pin insert; described cylinder type contact pin or conical contact pin are realized reliably contacting with fluting pipe surface; the pipe 1 of slotting this moment is outwards dug place's maximum outside diameter and is engaged with the protective sleeve inner surface; under the restriction of rigid protective cover 2; resilient slotted pipe 1 strain; contact pin is applied an entad chucking power, realize that contact pin contacts with the reliable of jack.Axially grooved length on the described pipe 1 is generally more than or equal to the contact length of the actual insertion of contact pin, and the other end of described fluting pipe 1 can be the cable connecting arrangement that is integrated into or connects by modes such as punching press, riveted joints.The internal diameter of the section of being inserted into of the pipe 1 of described receptacle portion can be uniform straight hole, also can be taper hole.In described receptacle portion, an end of described rigid protective cover 2 can be connected the other end of fluting pipe 1 opening by modes such as riveted joint, welding.
Implement the contact that is used for connector of the present utility model, because making contact pin and cooperating of jack be one, the design of the special construction of jack becomes the diameter process, its advantage is to insert and extract comparatively smooth, compare with the cooperation of plain cylindrical form contact pin jack, improved mechanical connect-disconnect life, and along with the insertion of contact pin, the corresponding increase of contact engaging and separating force, contact resistance reduces, and has improved the contact reliability of product.Specifically transferring passenger vehicle with the railway visitor according to the utility model trial-production is example with the three-phase dynamic connector, owing to adopt bocca contact pin and compound limit spring jack contact form, under 425 amperes of situations of 5 hours of operating voltage 380V energising, its contact is owing to contact good temperature rise less than 60 ℃, and the contact engaging and separating force of connector is controlled at both makes contact resistance reduce the control temperature rise, guarantee the life-span that the machinery plug is enough again and contact reliability is preferably arranged under adverse circumstances.
In conjunction with the accompanying drawings and embodiments, further specify characteristics of the present utility model, in the accompanying drawing:
