Description

The photovoltaic junction box connector that cable loosens and extracted
Technical field
The present invention relates to the technical field of photovoltaic junction box connector, the light for loosening and extracting more particularly to a kind of cable Lie prostrate junction box connector.
Background technology
Such as Fig. 1, the existing cable connector for photovoltaic junction box connector includes:Male-female coupling head nut, anti-loose clip Pawl, T-shaped sealing ring, copper plug-in unit, connection plug and connection socket, the copper plug-in unit includes copper jack, copper plug and cable, described Copper jack and copper plug are crimped by peelling off the cable of the end of a thread, the copper plug-in unit one in order through male-female coupling head nut, Locking clamping jaw, T-shaped sealing ring and connection socket, the copper plug-in unit other end is in order through male-female coupling head nut, anti-loose clip Pawl, T-shaped sealing ring and connection plug, the connection plug and connection socket access plastics Non-return ring by ultrasonic bonding.T-shaped is close Seal and the connection plug equipped with plastics Non-return ring and connection socket cooperation.O is provided between the connection socket and connection plug Type sealing ring.The contact surface position of the connection plug and copper jack is additionally provided with banana plug.
It is above-mentioned it is existing be used for photovoltaic junction box connector, installation, transport, using and artificially rotate cable, drag cable When, the cable connector that cable loosens, extracts connector easily occurs, causes connector to be failed because of wet electric leakage, or even get an electric shock Accident threat to life, until photovoltaic plant is paralysed.
After prior art is there is also the copper jack or copper plug are connected with the cable outside terminal box, injection molding packaging is in one In body, then by the body in plug-in unit set.The program is disadvantageous in that:Production cycle is longer, causes to produce It is less efficient.
The content of the invention
The technical problems to be solved by the invention are to provide the photovoltaic that a kind of pulling capacity is larger, safety and reliability is higher Junction box connector.
In order to solve the above technical problems, the invention provides a kind of photovoltaic junction box connector, it includes:Rear end is connected with cable Metal electrode be located in an adapter body, one be located on above-mentioned cable tightens up nut thread and is connected to above-mentioned adapter body Rear end;Between one stop collar is supported in the metal electrode and tightens up nut, to prevent the metal electrode from above-mentioned joint Pulled out in main body.
The stop collar includes:Annular sleeve and the pillar that axially extends of side wall along annular sleeve, the front end of pillar have to The boss radially extended, the boss are embedded in the breach of the metal electrode rear end, are formed in connector interior metal electricity The integrated support that pole passes through cable stop collar and locking nut.
Tightened up described in nut, the rear end of stop collar is provided with the wire bushing being sheathed on the cable and held down assembly;Stop collar, Wire bushing holds down assembly located at the metal electrode and tightens up between nut and form integrated support.
Compared with prior art, the technique effect that the present invention obtains:(1) stop collar of the invention is by integral pillar and annular sleeve Form, it uses high intensity, high electric property plastic manufacturing.The stop collar be supported in the metal electrode in connector afterbody and Between cable cover(ing) compacting ring sub-assembly, pillar is withstood at the half round cut of metal electrode rear end of connector, and annular sleeve is withstood Cable cover(ing) compresses coil assembly, is formed and is propped up in connector interior metal electrode by cable stop collar and the overall of locking nut Support.The connector of the present invention is installed, (pulling capacity i.e. between adapter body and cable is extremely in more than 400N.m for cable pulling capacity During few 400N.m, still the metal electrode can be avoided to be pulled out from above-mentioned adapter body), it fundamentally ensure that pulling capacity is more than The snap-in force of cable core and metal electrode terminal, it is ensured that permanent to avoid because spacing problem causes cable to loosen and extract.(2) originally The cable connector pulling capacity of invention is larger, security is higher, can avoid because connector is in installation, transport, use and people To rotate cable, drag cable generation cable loosens, extracts, and causes the wet electric leakage of connector and fails, or even electric shock accidents occurs Threat to life, until the hidden danger of photovoltaic plant paralysis.
Brief description of the drawings
Fig. 1 be prior art photovoltaic junction box connector structural representation, reference therein:1st, male-female coupling Head nut, 2, locking clamping jaw, 3, T-shaped sealing ring, 4, plastics Non-return ring, 5, copper jack, 6, banana plug, 7, connection plug, 8, O-shaped Sealing ring, 9, connection socket, 10, copper plug;
Fig. 2 is the structural representation of the photovoltaic junction box connector of the present invention;
Fig. 3 is the structural representation of the stop collar of the present invention.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
Photovoltaic junction box connector such as Fig. 1-3 the present embodiment includes:The metal electrode 11 that rear end is connected with cable 13 is located at one In adapter body 12, what is be located on above-mentioned cable 13 one tightens up the rear end that nut 14 is threaded in above-mentioned adapter body 12; Between one stop collar 15 is supported in the metal electrode 11 and tightens up nut 14, to prevent the metal electrode 11 from above-mentioned joint Pulled out in main body 12.
The stop collar 15 includes:Annular sleeve 151 and the pillar 152 that axially extends of side wall along annular sleeve 151, pillar 152 front end has to the boss 153 radially extended, and the boss 153 is embedded in the breach 110 of the rear end of metal electrode 11 In.
Tightened up described in nut 14, the rear end of stop collar 15 is provided with the wire bushing being sheathed on the cable and holds down assembly 16; Stop collar 15, wire bushing, which hold down assembly, 16 located at the metal electrode 11 and to be tightened up between nut 14 and forms integrated support, Pulling capacity between adapter body 12 and cable 13 can still avoid the metal electrode 11 from above-mentioned joint at least 400N.m Pulled out in main body.
The present invention solves the problems, such as that photovoltaic junction box connector cable pulling capacity is inadequate, can forever avoid because connector exists Installation, transport, using and artificially rotate cable, drag cable occur cable loosen, extract, cause connector it is wet electric leakage and lose Effect, or even electric shock accidents threat to life occurs, until photovoltaic plant is paralysed.
Obviously, above-described embodiment is only intended to clearly illustrate example of the present invention, and is not the implementation to the present invention The restriction of mode.For those of ordinary skill in the field, can also make on the basis of the above description it is other not With the change or variation of form.There is no necessity and possibility to exhaust all the enbodiments.And these belong to the present invention's Among the obvious changes or variations that spirit is extended out is still in protection scope of the present invention.
