Embodiment
As shown in Figure 1, male plug joint 1 comprises one and is provided with the split type slotting body 11 of internal cavity and is arranged on the resistance 12 and tensioning spring 13 that are in series with slotting body two ends in internal cavity.
Split type slotting body 11 is formed by connecting by slotting hat 111, insulating spacer 112 and an inserted link 113 being provided with cavity, wherein insert hat 111 and form left side cavity with insulating spacer 112, inserted link 113 inside is right side cavity, and left and right cavity is fixedly connected to form a sealing internal cavity by dismountable.
Be provided with resistance 12 and tensioning spring 13 at cavity inside, one end of resistance 12 is connected with slotting hat 111, and the other end is connected with tensioning spring 13, and tensioning spring is connected with the cavity interior walls of inserted link 113.
Insert hat 111 to be connected with insulating spacer 112 injection moulding, insulating spacer 112 is fixedly connected with inserted link 113 is dismountable; The design of this structure can realize sparkproof again can be for convenience detach, insulating spacer 112 and inserted link 113 be dismountable to be fixedly connected with as being threaded, eye-splice is connected, its object is exactly in needs production process, convenient installation, in use procedure, be convenient for changing internal resistance or other damaged parts; In order to ensure that electrodes conduct ability is good, its Each part is all answered compact and reliable, slotting hat 111 is connected convenient with insulating spacer 112 injection moulding by the utility model for this reason, one tensioning spring 13 is set between resistance 12 and inserted link 113, thus very large degree avoids produces the bad problem of contact because of split type slotting body.
Certainly, split type slotting body 11 also can be designed to slotting hat 111 and be fixedly connected with insulating spacer 112 is dismountable, and insulating spacer 112 and inserted link 113 are injection molded into one, and its object is and realizes detachable replacing internal resistance 12.
Preferably, it is inserted hat top and is provided with word groove or a cross recess, when mounting and dismounting insulating spacer 112 with inserted link 113, can use a word instrument or cross spiral instrument, thus can more labour-saving installing/dismounting public plug.
The effect of insulating spacer is exactly the slotting hat and the inserted link that cut off public plug 1, thus in public plug and female grafting moment, due to the shunting of resistance, can avoid producing electric spark, therefore insulating spacer selects insulating material usually, such as plastic parts, inserts hat and inserted link then selects to conduct electricity good columniform metal copper piece.
If Fig. 2 is that the utility model male and female plug inserts state mutually, the moment touching female is started at the slotting hat 111 of public plug, the flow direction of electric current is that female 2-public plug inserts hat 111-resistance 12-public plug inserted link 113, due to the existence of resistance, make immediate current can not be excessive, thus avoid producing pyrophoric behavio(u)r.
As shown in Figure 3, when the inserted link contact female of public plug, its insulating spacer no longer plays a role, and electric current directly will insert public plug by female 2.
In order to reach above sparkproof object, size for resistance value also has certain requirement, usually the power of device that we use varies, pyrophoric behavio(u)r is there is in the plug connector that all can appear at device in a lot of situation when plugging, according to different watt levels, the resistance value of the resistance 12 of use is also just different.
