Detailed Description

The block terminal block of the present invention will now be described in greater detail with reference to the schematic drawings, in which preferred embodiments of the invention are shown, it being understood that those skilled in the art may modify the invention herein described while still achieving the advantageous effects of the invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.

The invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in a very simplified form and are not to precise scale, which is only used for the purpose of facilitating and clearly explaining the embodiments of the present invention.

As shown in fig. 2, the embodiment of the utility model provides a block terminal row of connecting, including row of connecting body 1, wiring groove 2 and setting element 3.

The wiring grooves 2 are arranged on two sides of the wiring row body 1 and used for installing the wiring harnesses, so that the wiring harnesses on the two devices are butted to form a passage.

As shown in fig. 3, 4 and 5, in the present embodiment, a specific positioning member 3 is provided to quickly and stably connect the terminal block body 1 and the wire harness.

The positioning piece 3 comprises a bolt 31 and a concave hole 32, and the bolt 31 is rotatably installed in the wiring slot 2; the concave hole 32 is arranged inside the bolt 31, so that the wire harness wire penetrates into the concave hole 32 from the wiring groove 2.

Specifically, when bolt 31 receives external force to twist, pulls the pencil silk and winds the bolt 31 outer wall is rotatory, and bolt 31 is rotatory promptly, and shrinkage pool 32 inner wall can apply one to the pencil silk and twist the effort of moving around bolt 31 direction to twine the pencil silk on the outer wall of bolt 31, with the spacing effect of promotion bolt 31 to the pencil silk, and bolt 31 in follow-up rotation process, still extrude the pencil silk to with 2 diapire butts in wiring groove, thereby reach the purpose of connecting, can effectively save this step of bending the pencil silk in prior art, so reach when guaranteeing that wiring row body 1 is connected inseparable with the pencil silk, still effectively promote connection rate's purpose.

Referring to fig. 3, the top of the wire connecting bar body 1 is provided with an installation groove 4 for installing the bolt 31, the installation groove 4 and the wire connecting groove 2 form a T-shaped channel, so that the wire harness wire penetrates out of the concave hole 32 and abuts against the inner wall of the wire connecting groove 2, the wire harness wire is conveniently inserted into the wire connecting groove 2 and penetrates out of the concave hole 32, and the subsequent concave hole 32 rotates along with the bolt 31 to provide a winding torque force for the wire harness wire.

In addition, work as the bolt 31 upper surface with when the wiring row body 1 is leveled, the shrinkage pool 32 with wiring groove 2 communicates completely, and shrinkage pool 32 is unanimous with wiring groove 2 height promptly, and the staff passes shrinkage pool 32 with the pencil silk by wiring groove 2 when initial condition, reduces the degree of difficulty that the pencil silk penetrated.

As shown in fig. 4, in other embodiments, in order to further facilitate the penetration of the wire harness, the wiring groove 2 is configured as a "convex" structure, and the inner diameter of the wiring groove 2 increases gradually from outside to inside, that is, the opening diameter of the wiring groove 2 is smaller than the inner diameter thereof, so as to facilitate the guiding of the wire harness to pass through the concave hole 32, and also facilitate the winding of the wire harness at the inner wall of the wiring groove 2, thereby avoiding the occurrence of the jamming and the like when the wire harness is wound due to the too small inner volume of the wiring groove 2.

In a further embodiment, to further improve the stability of the connection of the bundle wires to the terminal block body 1. The inside gasket 5 that still is provided with of wire connection groove 2, just gasket 5 with bolt 31 cup joints mutually, makes when bolt 31 extrudees the pencil silk, the pencil silk and gasket 5 butt.

In addition, in order to facilitate the installation of the wiring block body 1, two sides of the wiring block body 1 are provided with extending edges 6, and fastening pieces 7 for connection are arranged on the extending edges 6, specifically, the fastening pieces 7 can be set to be screws.
