Abstract
The invention relates to the field of electrical connectors, in particular to a fireproof short-circuit electrical connector. The electrical connector comprises a shell component, more than two contact components are assembled in the shell component, each contact component comprises a contactor and a tail contact assembled in the shell component in tandem, a floating spring is mounted at the rear end of each contactor, each contactor in the initial state is in open-circuit with the corresponding tail contact, and shifting blocks used for shifting the contactors rearwards to enable the contactors to retract into corresponding mounting holes are further arranged on the shell component. When an aircraft is launched, each contactor and the corresponding tail contact are in open circuit, and short circuit of corresponding equipment cannot be caused; when the aircraft is assembled, the shifting blocks are shifted to enable the contactors to retract into the shell component so as to prevent the contactors from being damaged; after the aircraft is assembled, the shifting blocks are released. Thus, by the fireproof short-circuit electrical connector, the problem that contactors of an existing short-circuit electrical connector are in short circuit accidentally easily and damaged by the aircraft easily is solved.
Description
Technical field
The present invention relates to electric connector field, particularly relate to a kind of fire-type short-circuit electric connector.
Background technology
Along with the constantly integrated of electric equipment and modularization development, electric connector is obtained for and applies more and more widely in the fields such as communication, electric power, Aero-Space.In most cases, electric connector is applied to switching on and off of circuit.But, in the occasion that some are special, also require that electric connector possesses some other function, it is such as the launcher of the aircraft of power source with fuel combustion, its electric connector used then to require after aircraft grafting between contact can short circuit be to provide detection signal to aircraft mutually, and the electric connector of the mutual short circuiting work between this dependence contact is commonly referred to as short-circuit electric connector.
Shown in Fig. 1 is exactly a kind of short-circuit electric connector, as can be seen from the figure, this short-circuit electric connector comprises housing parts 51 and is assemblied in the contact parts in housing parts 51, contact parts comprise afterbody contact 52 and the contact 53 corresponding with afterbody contact 52, wherein the tail end of contact is enclosed within corresponding afterbody contact and also can slides along afterbody contact, in addition, floating spring 54 is also top-loaded with between the tail end of contact and housing parts, when pushing up pressure contact backward, it can compress floating spring and in retraction housing parts.Due to the existence of described floating spring, expose under contact free state outside housing parts, in time assembling aircraft, the unavoidable meeting of contact collides with aircraft, and then damaged; In addition, owing to keeping the state of mutual grafting between afterbody contact and corresponding contact always, when aircraft igniting is launched, the thermal-flame direct effect that its afterbody produces is to contact and then cause mutual short circuit between contact, and contact is once short circuit, then afterbody contact just can short circuit accordingly, as the signal transduction component of aircraft, short-circuit electric connector certainly can not arbitrarily short circuit at any time, once produce the situation of accidental short circuit, then very likely cause the damage of the control appliance on launcher, and then bring immeasurable loss; It is particularly coaxial configuration between its contact and corresponding afterbody contact, owing to being subject to the restriction of overall dimension, spacing between afterbody contact is limited, and directly reaction must be limited suffered by spacing between afterbody contact on contact, this then further increases the possibility of short circuit between adjacent contact; Meanwhile, because the rear end of afterbody contact is without corresponding operator guards, this position also form the weak link of easy accidental short circuit.
In addition, above-mentioned various problem also directly causes current short-circuit electric connector can only use as expendable consumed product, and this obviously causes great waste.
Summary of the invention
The object of the present invention is to provide a kind of fire-type short-circuit electric connector, with the easy accidental short circuit of the contact solving current short-circuit electric connector with easily by problem that aircraft breaks.
In order to solve the problem, fire-type short-circuit electric connector of the present invention is by the following technical solutions: fire-type short-circuit electric connector, comprise housing parts, plural contact parts are equipped with in housing parts, contact parts comprise and are one in front and one in back assemblied in contact in housing parts and afterbody contact, the rear end of contact is top-loaded with floating spring, contact in an initial condition with the corresponding mutual open circuit of afterbody contact, housing parts is also provided with for stirring contact backward to make the shifting block in the corresponding installing hole of its retraction.
At least one contact is connected with for the sleeve with corresponding afterbody contact grafting by keyset, and sleeve is coaxially arranged with corresponding afterbody contact, and floating spring top is contained between sleeve and housing parts.
Sleeve comprises the jack be fixed on corresponding keyset and the insulation fairlead be enclosed within jack, and insulation fairlead leads with corresponding afterbody contact and coordinates.
Described shifting block and keyset are fixed together.
Lead along the longitudinal direction and be equipped with the sleeve of shifting block in the outside of housing parts, sleeve is provided with the tooling hole snapped in for force application means.
Housing parts is fixedly equipped with fireproof covering in the rear end of described afterbody contact, and fireproof covering is enclosed within corresponding afterbody contact.
In this fire-type short-circuit electric connector, because the rear end of contact is top-loaded with floating spring, and contact in an initial condition with the corresponding mutual open circuit of afterbody contact, therefore, when vehicle launch, contact gets back to initial position instantaneously under the effect of floating spring, even now mutual short circuit between contact, owing to being open circuit between itself and corresponding afterbody contact, also the short circuit of relevant device can not be caused, in addition, owing to housing parts being also provided with for stirring contact backward to make the shifting block in the corresponding installing hole of its retraction, when assembling aircraft, can first make in contact retraction to housing parts by stirring described shifting block to prevent it from being broken, after aircraft installs, release shifting block, then contact moves forward until connect with aircraft under the effect of floating spring.As can be seen here, this fire-type short-circuit electric connector easy accidental short circuit of contact of solving current short-circuit electric connector and easily by problem that aircraft breaks.
Further, keyset and sleeve be arranged so that can be suitable when not changing the spacing between afterbody contact increase contact between distance, play against short-circuit effect further; Fairlead ensure that the direction of motion of short-circuit board and contact; Shifting block is fixedly connected with short-circuit board and can reduces the degree of depth that it inserts housing parts; Sleeve further can facilitate stirring contact; Fireproof covering effectively protects the rear end of tail end contact, realizes preventing fires without dead angle of fire-type short-circuit electric connector of the present invention.
