Abstract
The invention provides an electric connector which comprises a casing, a thimble, an upper magnetic body and a lower magnetic body. The casing forms a hollow shape, one end is provided with an opening, and the end is provided with a stop catch part. One end of the thimble is clamped in the casing, and the other end passes through the opening and is extended out of the casing. The upper magnetic body is fixedly arranged on the thimble; the lower magnetic body is fixedly arranged on the other end of the casing opposite with the end of the stop catch part; and the polarities of opposite magnetic poles of the lower magnetic body and the upper magnetic pole are the same. The electric connector is provided with a pair of mutually exclusive magnetic bodies respectively fixed on the casing and the thimble, the problems of overheat, and the like can not appear when being used, and the thimble can automatically decline to make the thimble be stably guided and connected with the casing.
Description
Affiliated technical field
The present invention relates to a kind of electric connector, relate in particular to a kind of thimble-type electric connector.
Background technology
Existing electric connector adopts elastomer such as spring that resiliency urged power is provided usually and corresponding piece is stable contacts, and sees also Fig. 1, and a kind of existing electric connector 100 ' comprises housing 1 ', thimble 2 ' and spring 5.Housing 1 ' is the cylindrical of a hollow, and the one end is provided with an opening 14 ', and the other end then is sealing, thereby forms a receiving space 13 '.Thimble 2 ' one end is fastened in the receiving space 13 ', and the other end stretches out outside the housing 1 ' through opening 14 ', and the bottom surface of this thimble 2 ' is an inclined-plane.Spring 5 places the receiving space 13 ' of housing 1 ', the one end is replaced housing 1 ', the other end is replaced the inclined-plane of thimble 2 ' bottom, thereby makes thimble 2 ' produce deflection when start and be resisted against on the inwall of housing 1 ', makes thimble 2 ' and housing 1 ' reach stable the contact.
Yet above-mentioned existing electric connector 100 ' needs spring 5 that elastic force is provided, because spring 5 has the characteristic of high impedance, easily produces high temperature when electric current flows through.Excessive when electric current, the heat that produces when flowing through spring 5 can burn spring 5 or coat the plastic casing (not shown) etc. of the housing 1 ' of this electric connector 100 '.In addition, phenomenons such as fatigue can appear in spring 5 another defectives that can't overcome own after promptly long-term the use, influence its elastic performance, reduce its stability.Simultaneously, form stable contacting in order to make thimble 2 ' with the inwall of housing 1 ', the inclined-plane need be processed into usually in the bottom surface of thimble 2 ', causes the cost of manufacture of electric connector 100 ' to increase.
Summary of the invention
The objective of the invention is to provide a kind of at the problem that above-mentioned prior art exists and make simply, connect stable electric connector, this electric connector is of compact construction, good performance reaches long useful life.
For achieving the above object, a kind of electric connector provided by the invention comprises housing, thimble, upper magnet and lower magnet.Housing is hollow form, and the one end has an opening, and this end is provided with a stopper section.One end of this thimble is fastened in the housing, and its other end passes opening and stretches out outside the housing.This upper magnet is installed on the thimble.This lower magnet is installed on the housing other end relative with place, stopper section end, and the polarity of this lower magnet magnetic pole relative with upper magnet is identical.
In sum, the present invention substitutes the spring of existing electric connector by a pair of magnet that is installed in respectively on housing and the thimble and repels mutually is set, thus problems such as overheated, the fatigue that produces when having avoided using spring; And electric connector in use, and therefore the automatic deflection of its thimble meeting no longer needs the inclined-plane is processed in the probe bottom surface, has reduced cost; In addition, owing to do not need spring, therefore compared to existing electric connector with spring, electric connector of the present invention can be compacter, and is small and exquisite.

Embodiment
By describing technology contents of the present invention, structural feature in detail, being reached purpose and effect, described in detail below in conjunction with embodiment and conjunction with figs..
See also Fig. 2, electric connector 100 of the present invention comprises that one is the metal shell 1 of hollow cylindrical.The upper end of this housing 1 has an opening 14, and this end forms the stopper section 11 of an annular to opening 14 inner bendings.The lower end of housing 1 is sealed by an end cap 12, thereby forms a host cavity 13 in housing 1.
Be equipped with a cross section and slightly be the thimble 2 of convex shape in above-mentioned host cavity 13, this thimble 2 comprises that a cylindrical sliding part 21 and is from the sliding part 21 vertically extending contact site 22 that makes progress.Sliding part 21 is fastened in the host cavity 13 of housing 1 fully, and the diameter of this sliding part 21 is greater than the diameter of stopper section 11 middle openings 14, thereby stopper section 11 can be replaced to avoid deviating from sliding part 21 upper surfaces of thimble 2 in metal shell 1.The bottom face of this sliding part 21 columniform groove 211 that sets to the concave.22 of contact sites come out from opening 14 projections.
One cylindrical upper magnet 3 is installed in the groove 211.One columniform lower magnet 4 is installed on the upper surface of end cap 12 of housing 1, and is positioned at the position relative with upper magnet 3.This upper magnet 3 and lower magnet 4 are permanent magnet, and near the magnetic field that produces its lower surface of upper magnet 3 and lower magnet 4 repel in the magnetic field that produces of near surface thereon mutually.Particularly, promptly when the lower end of upper magnet 3 was the N utmost point, the upper end of lower magnet 4 also was the N utmost point, and perhaps when the lower end of upper magnet 3 was the S utmost point, the upper end of lower magnet 4 also was the S utmost point.According to magnetic pole homopolar-repulsion principle, upper magnet 3 will repel under magnetic field effect mutually with lower magnet 4, thereby form the effect of a spring-like, make the thimble 2 that is in the host cavity 13 have to the trend of opening 14 directions motion and replace the stopper section 11 of housing 1.Above-mentioned upper magnet 3 and lower magnet 4 can adopt stickup, inlay, utilize different ways such as screw is fixing to be installed on the corresponding position.
See also Fig. 3, when application element thereof connect the contact (not shown) when compressing thimble 2 because the effect that is under pressure, thimble 2 will overcome the magneticaction between upper magnet 3 and the lower magnet 4 and move down.After stable, this thimble 2 will be in the state of a stress balance, and what the contact site 22 of thimble 2 upper ends was replaced application element thereof under magneticaction connects the contact (not shown), makes the stable electric connection of formation between thimble 2 and the application element thereof (not shown).Yet, thimble 2 is compressed by the contact (not shown) that connects of application element thereof, make its stress balance in a longitudinal direction, but owing to have the gap between the inwall of housing 1 and the thimble 2, the magneticaction that repelled mutually by upper magnet 3 and lower magnet 4, thimble 2 still is in an unsure state in a lateral direction, for reaching stress balance, deflection will take place and form electric connection against the inwall of housing 1 in thimble 2, thereby makes application element thereof (not shown) and housing 1 realize electrically conducting.
