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, more particularly to a kind of fire-type short-circuit electric connector.
Background technology
With the continuous integrated and modular development of electrical equipment, electric connector is led in communication, electric power, Aero-Space etc.
It is obtained in domain and is increasingly widely applied.In most cases, electric connector be applied to circuit connection and
Disconnect.However, in some special occasions, also requiring that electric connector possesses some other functions, such as with fuel combustion being
The launcher of the aircraft of power source, the electric connector used by which are then required in energy between contact after aircraft grafting
Enough it is shorted with each other to provide detection signal to aircraft, the electric connector for being shorted with each other work between this dependence contact leads to
Short-circuit electric connector is referred to as often.
Shown in Fig. 1 is exactly a kind of short-circuit electric connector, it can be seen that the short-circuit electric connector includes housing
Part 51 and the contact part being assemblied in housing parts 51, contact part are included afterbody contact 52 and are connect with afterbody
52 corresponding contact 53 of contact element, the tail end of wherein contact are enclosed within corresponding afterbody contact and can slide along afterbody contact,
In addition, being also top-loaded with floating spring 54 between the tail end and housing parts of contact, when top pressure contact backward, which can compress floating
Move in spring retraction housing parts.Due to the presence of the floating spring, expose under contact free state housing parts it
Outward, when aircraft is assembled, the unavoidable meeting of contact is collided with aircraft, and then is damaged；Further, since afterbody connects
The state for mutually plugging is always maintained between contact element and corresponding contact, when aircraft igniting is launched, the height that its afterbody is produced
Warm fire flame direct effect is to contact and then causes being shorted with each other between contact, and contact is once short-circuit, then afterbody contact
Will be short-circuit accordingly, used as the signal transduction component of aircraft, short-circuit electric connector certainly can not be arbitrarily short at any time
Road, once producing the situation of accidental short circuit, then very likely causes the damage of the control device on launcher, and then bring can not
The loss of appraisal；It is coaxial configuration to be particularly between its contact and corresponding afterbody contact, due to being limited by overall dimensions
System, the spacing between afterbody contact are limited, and must limit direct reaction suffered by the spacing between afterbody contact and exist
On contact, this then further increases the probability of short circuit between adjacent contact；Simultaneously as the rear end of afterbody contact without
Corresponding protection structure, also form the weak link of easy accidental short circuit at the position.
In addition, above-mentioned various problems also directly result in current short-circuit electric connector can only make as expendable consumed product
With this obviously causes greatly waste.
The content of the invention
It is an object of the invention to provide a kind of fire-type short-circuit electric connector, to solve current short-circuit electric connector
The easy accidental short circuit of contact and the problem for easily being broken by aircraft.
In order to solve the above problems, the fire-type short-circuit electric connector of the present invention is employed the following technical solutions：Fire-type is short
Road electric connector, including housing parts, is equipped with plural contact part in housing parts, contact part includes one
The contact being assemblied in after previous in housing parts and afterbody contact, the rear end of contact are top-loaded with floating spring, and contact is initial
It is breaking mutually with corresponding afterbody contact under state, it is additionally provided with housing parts for stirring contact backward so that its retraction phase
Shifting block in the installing hole answered.
At least one contact is connected with for the sleeve with corresponding afterbody contact grafting by pinboard, sleeve with it is right
The afterbody contact answered is coaxially disposed, and floating spring top is mounted between sleeve and housing parts.
Sleeve includes the jack being fixed on corresponding pinboard and the insulation fairlead being enclosed within jack, and insulate fairlead
It is oriented to corresponding afterbody contact and coordinates.
The shifting block is fixed together with pinboard.
The outside of housing parts is oriented to the sleeve for being equipped with shifting block along the longitudinal direction, and sleeve is provided with and snaps in for force application means
Tooling hole.
Rear end fixing assembling on housing parts in the afterbody contact has fireproof covering, and fireproof covering is enclosed within corresponding tail
On portion's contact.
In the fire-type short-circuit electric connector, as the rear end of contact is top-loaded with floating spring, and contact initial
It is breaking mutually with corresponding afterbody contact under state, therefore, when vehicle launch, contact wink in the presence of floating spring
Between return to initial position, even being now shorted with each other between contact, due to its between corresponding afterbody contact be open circuit
, the short circuit of relevant device is also not result in, further, since being additionally provided with housing parts for contact being stirred backward so that its contracting
Enter the shifting block in corresponding installing hole, when aircraft is assembled, contact retraction can be made extremely by stirring the shifting block first
To prevent which from being broken in housing parts, after aircraft is installed, shifting block is discharged, then contact is in the presence of floating spring
Reach is until connect with aircraft.As can be seen here, the fire-type short-circuit electric connector solves current short-circuit electric connector
The easy accidental short circuit of contact and the problem for easily being broken by aircraft.
Further, the setting of pinboard and sleeve is so that can be in the situation of the spacing not changed between afterbody contact
The distance between increase contact appropriate down, further functions as anti-short circuit effect；Fairlead ensure that short-circuit board and contact
The direction of motion；Shifting block is fixedly connected the depth that can reduce its insertion housing parts with short-circuit board；Sleeve can be further
It is convenient that contact is stirred；Fireproof covering is effectively protected the rear end of tail end contact, realizes the fire-type short circuit electricity of the present invention
Adapter without dead angle prevent fires.
