Description
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.
