The embodiment of the utility model is realized in such a way that an improved rail joint comprises:

the front cover, front cover fixedly connected with ground wire iron sheet, ground wire iron sheet fixedly connected with binding post platform, the ground wire iron sheet is located in the front cover, binding post platform fixedly connected with plastic head, plastic head joint conducting strip, plastic head fixedly connected with shell fragment, the shell fragment is contradicted the conducting strip, binding post platform threaded connection has the line ball screw, line ball screw swing joint has the line ball piece.

As a further scheme of the utility model, the number of the line pressing screws is 3, and the number of the line pressing screws is the same as that of the line pressing sheets.

As a further scheme of the utility model, the front cover is in threaded connection with a front cover screw.

As a further scheme of the utility model, the ground wire iron sheet is detachably connected with a wire pressing plate.

As a further aspect of the present utility model, the two-wire track comprises an improved track joint as described in any one of the above, comprising: the track, track fixedly connected with wiring protecgulum, track fixedly connected with adhesive tape, adhesive tape fixedly connected with protection strip.

Compared with the prior art, the utility model has the beneficial effects that: the original track joint is externally leaked by the power connection screw without any electric shock protection, and the electric shock protection is added at present, so that a safe electric shock protection wiring structure is realized, and the convenience of wiring is greatly improved; the prior track joint has no structure of line pressing and any line locking, and now, the line pressing sheet and the line pressing plate are added to protect the wiring points from being broken by external force below 32N, so that accidental electric leakage can be avoided; the earth connection of former track joint belongs to outer hourglass formula earth connection, and the earth connection of plugging into is inconvenient when the user uses, and outward appearance effect is also not good moreover, can be more convenient safe wiring now to the outward appearance is clean and tidy generous.

Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Specific implementations of the utility model are described in detail below in connection with specific embodiments.

As shown in fig. 1 to 5, an improved rail joint according to an embodiment of the present utility model comprises:

the front cover 9, the front cover 9 fixedly connected with ground wire iron sheet 5, ground wire iron sheet 5 fixedly connected with binding post platform 4, ground wire iron sheet 5 is located in the front cover 9, binding post platform 4 fixedly connected with plastic head 1, plastic head 1 joint conducting strip 3, plastic head 1 fixedly connected with shell fragment 2, shell fragment 2 is contradicted conducting strip 3, binding post platform 4 threaded connection has line ball screw 7, line ball screw 7 swing joint has line ball piece 6.

In this embodiment, the terminal block 4 is screwed with a fixing screw 8, and the fixing screw 8 penetrates through the conductive sheet 3 and the plastic head 1 to be fixedly connected with the terminal block 4; the number of the wire pressing screws 7 is 3, the number of the wire pressing screws 7 is the same as that of the wire pressing sheets 6, and the wire pressing sheets 6 are driven to abut against the wires by rotating the wire pressing screws 7 so as to be matched with the wiring terminal table 4 to fix the wires; the ground wire iron sheet 5 is detachably connected with a wire pressing plate 11, through holes for matching with screws are formed in the wire pressing plate 11, the through holes are symmetrically distributed on two sides of the wire pressing plate 11, and the screws penetrate through the through holes and are in threaded connection with the ground wire iron sheet 5, so that wires between the wire pressing plate 11 and the ground wire iron sheet 5 are fixed; the front cover 9 is in threaded connection with a front cover screw 10, and the front cover screw 10 is used for lowering the front cover 9 to be installed at a preset position; the original track 12 joint is externally connected with the electric screw and is not subjected to any electric shock protection, and the electric shock protection is added at present, so that a safe electric shock-proof wiring structure is realized, and the convenience of wiring is greatly improved; the prior rail 12 joint has no structure of line pressing and any line locking, and now the line pressing sheet 6 and the line pressing plate 11 are added to protect the wiring points from being broken by external force below 32N, so that accidental electric leakage can be avoided; the earth connection of former track 12 joint belongs to outer hourglass formula earth connection, and the earth connection of plugging into is inconvenient when the user uses, and outward appearance effect is also not good moreover, can be more convenient safe wiring now to the outward appearance is clean and tidy generous.
