Abstract
The utility model relates to a locking force-strengthened photovoltaic connector. The locking force-strengthened photovoltaic connector includes a male head connector and a female head connector which are connected with each other; the male head connector and the female head connector both comprise a connector main body and a cable line which is locked at one end of the connector main body through a nut; one end of the connector main body is provided with a screw thread portion; the outer side of the screw thread portion is provided with elastic rods in an extending manner; the elastic rods are circumferentially and evenly distributed at the outer side of the screw thread portion so as to form a clamping portion; the nut is screwed on the screw thread portion; and the elastic rods are matched with the nut in length. According to the locking force-strengthened photovoltaic connector of the utility model, the clamping portion is arranged at the outer side of the screw thread portion, and the clamping portion can further clamp the cable line in the screwing process of the nut, and therefore, a locking force for the cable line can be greatly strengthened. Thus, the locking force-strengthened photovoltaic connector has the advantages of higher tensile performance, enhanced sealing performance and prolonged service life.
Description
(1) technical field
The utility model relates to a kind of photovoltaic connector.
(2) background technology
In field of photovoltaic power generation, photovoltaic junction box and photovoltaic connector are conventional critical pieces, and different electric currents collect by cable, and cable connects by photovoltaic connector.The connection reliability of cable in terminal box and on connector is one of index of passing judgment on terminal box, connector performance detection, in prior art, after cable is connected in connector or terminal box, then be to lock by nut, along with the lengthening of service time, nut coupling mechanism force can be faded, and sealing property weakens gradually, affects like this useful life.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of connection photovoltaic connector that coupling mechanism force is strengthened more reliably.
The technical scheme in the invention for solving the technical problem is:
The photovoltaic connector that a kind of coupling mechanism force is strengthened, comprising can interconnective Male head connector and female connector, Male head connector and female connector include connector body and are locked at the cable of connector body one end by nut, it is characterized in that: one end of described connector body arranges threaded portion, the outside extension of threaded portion is provided with elastic rod, described elastic rod is circumferentially evenly distributed on outside, threaded portion and forms clamping section, described nut is tightened on threaded portion, the length of the length coupling nut of described elastic rod.
As preferably, the inner surface of elastic rod and outer surface are all set to cambered surface.
As preferably, in connector body, be embedded with metal basket, in metal basket, be connected with metallic conduction part, described cable clamps on described metallic conduction part.
As preferably, hole clipping is set on metal basket, the latch that snaps in hole clipping is set on the outer surface of described metallic conduction part, described latch is set to slope.
As preferably, cable is also arranged with sealing plug sleeve outward.
Extend in the outside of threaded portion the clamping section being surrounded by elastic rod is set, cable screws nut after being inserted in the screw of threaded portion, nut screws in process, the clamping section that elastic rod surrounds progressively clamps cable, has greatly strengthened the coupling mechanism force of cable, has extended useful life.Conductor wire in cable is fixed on metallic conduction part, then is fixed in connector body by metal basket, and the outer sheathed sealing plug cover of cable, can dustproof and waterproof.
The beneficial effects of the utility model are: the utility model is by the setting of clamping section outside threaded portion, nut screws clamping section in process cable is further clamped, and has greatly strengthened the coupling mechanism force of cable, has more tensile property, strengthen sealing property, extended useful life.
