Abstract

The invention relates to a cable connector of a photovoltaic system used in a photovoltaic solar power generation system. Connectors connected with insulated rubber sleeves of cables to be connected in a matched way are connected to the tails of a plug housing and a socket housing respectively; each connector comprises a screw sleeve, and the inner diameter of the tail of each screw sleeve is gradually reduced; a rubber sealing sleeve is arranged in the screw sleeve, and an elastic sleeve is arranged at the tail of each rubber sealing sleeve in a sleeving manner; an annular shoulder is arranged on the outer circumference of the rubber sealing sleeve, one end surface of each annular shoulder is in contact with the end surface of the tail of the plug housing or the socket housing to achieve a limiting effect, and the other end surface of the annular shoulder is in contact with the front end surface of each elastic sleeve to achieve the limiting effect; the tail of the elastic sleeve has a gradually reduced outer diameter matched with the gradually reduced inner diameter of the tail of the screw sleeve, and a plurality of longitudinal slots are formed in the circumference of the rear section of the elastic sleeve. The cable connector is simple in structure and convenient and reliable to mount, and is improved in waterproof sealing performance.

Description

Photovoltaic system cable connector

Technical field

The present invention relates to a kind of photovoltaic system cable connector for photovoltaic solar electricity generation system.

Background technology

Common cable connecting arrangement conventionally can only carry out conventional conduction and connect and exterior insulation, in photovoltaic solar electricity generation system, particularity due to operational environment, the water-tight performance requirement that cable is connected is higher, and existing cable connector is difficult to meet the requirement that photovoltaic system cable connects.

Summary of the invention

Technical problem to be solved by this invention is, provide a kind of easy to use, connect the photovoltaic system cable connector reliable, water-tight is good.

Photovoltaic system cable connector of the present invention comprises plug casing and the Socket casing that mutual grafting coordinates, in plug casing and Socket casing, be respectively arranged with conductive pin and the conductive jack of socket connection mutually, the afterbody of described conductive pin and conductive jack can be connected with the center conductor of two sections of cables to be connected respectively; The afterbody of described plug casing and Socket casing is connected with respectively the joint being connected for the insulating gum cover with cable to be connected; Described joint comprises a swivel nut, and swivel nut front end is connected with the afterbody of plug casing or Socket casing by screw thread; Swivel nut afterbody is provided with the hole that penetrates that insulating gum cover for cable to be connected enters, and the internal diameter of swivel nut afterbody dwindles gradually; In swivel nut, be provided with a rubber sealing boot outside the insulating gum cover that can be enclosed within cable to be connected, rubber sealing boot afterbody cover has a resilient sleeve; On the excircle of rubber sealing boot, be provided with annular shoulder, an end face of annular shoulder contacts spacing with the tail end face of plug casing or Socket casing, and the front end face contact of another end face resilient sleeve of annular shoulder is spacing; The afterbody of described resilient sleeve have match with the diminishing internal diameter of swivel nut afterbody diminishing external diameter, simultaneously on resilient sleeve back segment circumference, have a plurality of slits longitudinally, make the diameter of the back segment of resilient sleeve can Flexible change.

Described swivel nut periphery is provided with for increasing the decorative pattern of coefficient of friction.

The logical rubber sealing boot of the present invention completes the end face seal of housing afterbody simultaneously and waits the excircle sealing of stube cable, and it is simple in structure, easy installation and reliable, has improved the waterproof sealing performance of photovoltaic system cable connector.

Embodiment

As shown in the figure, this photovoltaic system cable connector comprises plug casing 1 and the Socket casing 2 that mutual grafting coordinates, in plug casing and Socket casing, be respectively arranged with conductive pin 3 and the conductive jack 4 of socket connection mutually, the afterbody of described conductive pin and conductive jack can be connected with the center conductor L1 of two sections of cable L to be connected respectively; Described plug casing and Socket casing afterbody are connected with respectively the joint 5 being connected for the insulating gum cover L2 with cable L to be connected; Described joint comprises a swivel nut 51, and swivel nut front end is connected with the afterbody of plug casing 1 or Socket casing 2 by screw thread; Swivel nut 51 afterbodys are provided with the hole that penetrates that insulating gum cover for cable to be connected enters, and the internal diameter of swivel nut 51 afterbodys dwindles gradually; In swivel nut 51, be provided with a rubber sealing boot 52 outside the insulating gum cover L2 that can be enclosed within cable to be connected, rubber sealing boot afterbody cover has a resilient sleeve 53; On the excircle of rubber sealing boot, be provided with annular shoulder 521, an end face of annular shoulder 521 contacts spacing with the tail end face of plug casing 1 or Socket casing 2, and another end face of annular shoulder 521 contacts spacing with the front end face of resilient sleeve 53; The afterbody of described resilient sleeve 53 have match with the diminishing internal diameter of swivel nut 51 afterbody diminishing external diameter, simultaneously on resilient sleeve 53 back segment circumference, have a plurality of slits longitudinally, make the diameter of the back segment of resilient sleeve can Flexible change.

In installation process of the present invention, first rubber sealing boot 52, resilient sleeve 53 and swivel nut 51 are together enclosed within on cable L to be connected, then cable L front end is penetrated to plug casing 1 or Socket casing 2, swivel nut 51 is threaded with plug casing 1 or Socket casing 2, in screwing the process of swivel nut 51, because swivel nut afterbody internal diameter dwindles gradually, therefore oppress resilient sleeve 53 tail diameter and dwindle, and then compressing rubber sealing boot shroud ring is on cable L, realizes the sealing of cable excircle; Shoulder 531 on rubber sealing boot 52 excircles is pressed between resilient sleeve front end face and the rear end face of plug casing 1 or Socket casing 2 simultaneously, has realized the end face seal of plug casing 1 or Socket casing 2.
