Description

A kind of cable jockey

Technical field

The utility model relates to a kind of connector, specifically is a kind of cable jockey.

Background technology

Present widely used cable connected mode mainly contains to tie up and connects or two kinds of connected modes of concentric reducer crimping, it is loaded down with trivial details that above-mentioned connected mode not only exists operation sequence, job schedule is problem slowly, and exist to connect insecure disengaging or service time long aging hidden danger, also may cause the cable heating cable that fuses because of bad connection, cause line interruption, troubles such as maintenance difficult.And Patent Office of the People's Republic of China is that the utility model patent file of ZL02223435.7 discloses a kind of cable branch connector in the application number of on March 26th, 2003 bulletin, its feature is to make connector with metallic object, and on metallic object, do the jack that is parallel to each other that power supply cable the end of a thread inserts, after inserting in the jack of metallic object respectively, the cable the end of a thread at two ends clamps envelope stringing head, increased the contact-making surface of cable the end of a thread and connector effectively, improved conductive effect, make current flowing smooth and easy, but by clamp or the mode of envelope stringing head connect still have because of folder tight or envelope does not tightly come off may, and such connected mode needs to carry out in the erecting bed, operate also relatively loaded down with trivial detailsly, change also cumbersome.

Summary of the invention

At above-mentioned existing in prior technology problem, the purpose of this utility model provides a kind of easy to install, the strong and simple firm cable jockey of connected mode of joint conductivity.

For achieving the above object, the technical scheme that the utility model adopted is: a pair of jockey that comprises the mutual butt joint of being made by metal material, described jockey is provided with the guide hole that is parallel to each other that power supply cable the end of a thread inserts, it is characterized in that described jockey comprises that the bottom is provided with externally threaded connector, Connection Block and the rotatable attaching nut who is connected on the Connection Block that power supply cable the end of a thread passes, above-mentioned guide hole is arranged on the connector, described cable the end of a thread inserts in the guide hole of connector and cooperates with external screw thread on the connector by the attaching nut and fixes, in described two connectors that connect one of them is provided with screw thread, another is provided with nut, and described two jockeys cooperate realization to connect by the screw thread of two connectors with nut.Before being installed, cable can earlier Connection Block and cable be connected and fixed, and connector spun with it, during installation cable is secured to the relevant position after, two connectors are being cooperated fixing the getting final product that spin, it is easy for installation, firm, can not come off because of outside cause; It is also convenient to change, and it is promptly replaceable only need to turn on nut.

The relative Connection Block rotation of guide hole butt joint back connector when tightening the attaching nut of cable the end of a thread and connector and cause the distortion of cable the end of a thread to fracture on the Connection Block, the utility model convexes with the inserted block of a location in the bottom of above-mentioned connector, also be correspondingly provided with the slot that matches with described inserted block on the described Connection Block, so inserted block also docked the location mutually with slot when cable the end of a thread docked with the guide hole of connector, thereby connector and Connection Block relative fixed are avoided causing cable the end of a thread to twist accidentally when spinning and are fractureed when tightening the attaching nut.Cooperate with slot except inserted block is set, also the design of the inner chamber of connector can be polygon cavity or oval body or anomalistic object, and Connection Block also respective design be identical shaped pedestal, so cooperation also can prevent the relative Connection Block rotation of connector.

In order to prevent that the cable the end of a thread that passes Connection Block from coming off from Connection Block, present embodiment is connected with contact passing on cable the end of a thread of Connection Block, and be provided with spring in described contact lower end, described spring not only can work to lead straight cable line the end of a thread, and can play the effect that buffering cable the end of a thread is torn when cable is pullled.

Two cables are connected for convenience, wherein connector in two connectors that the utility model will be connected is designed to jack, another connector is designed to plug, above-mentioned described screw thread is arranged on the periphery of described jack, above-mentioned nut is rotating to be arranged on the described plug, described jack and plug plug together and by nut and screw thread screwed in place, thereby realize that two jockeys are connected.Above-mentioned guide hole respectively from the bottom end face of connector through to the hole of jack at the bottom of and on the end face of plug.

Two cable the end of a thread rotation and cause distortion to fracture relatively when fastening nut in like manner for fear of two cable the end of a thread butt joint back, so on the inwall of above-mentioned jack, be provided with a card post, the position of the corresponding jack card of above-mentioned plug post offers screens, and the card post of above-mentioned jack fastens with the screens of plug and makes the guide hole of two cables corresponding one by one.Be convenient rotation nut, the utility model becomes to have the plum blossom shape of anti-skidding effect with the periphery design of above-mentioned nut.

The utility model is because the structure that adopts nut and jockey to spin mutually two cable the end of a thread are firmly connected, dexterously with on the rotating Connection Block that is connected to jockey of nut, and screw thread is set on connector spins mutually with nut, guaranteed that effectively cable the end of a thread can be securely fixed on the jockey, described two jockeys also are to be connected with screw thread by nut is set, fast firm again when so connection is installed, effectively improved operating efficiency and work quality; Again owing to prevent both counterrotating positioners being provided with between Connection Block and the connector and between two connectors that join, thereby having guaranteed fully that two cable the end of a thread can not twist relatively when spinning fractures, further guaranteed the compactness that connects, simultaneously also improve conductive effect, helped the smooth and easy circulation of electric current.In sum, cable jockey described in the utility model has fundamentally solved existing cable and has connected the difficult problem insecure, that operation sequence is loaded down with trivial details, and improved conductive effect, use reliable and secure, its design is ingenious, have advantages such as solid and reliable, easy for installation, long service life, can be widely used in the connection of camera on the highway or other outdoor apparatuses.

The utility model is described in further detail below in conjunction with drawings and Examples.
