Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. In addition, in the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1 to 6, the present invention provides a three-connection blind-mate connection terminal, which comprises a ceramic joint and a plurality of square connection pieces arranged in the ceramic joint, wherein the square connection pieces are all fixedly connected to the ceramic joint.

In this embodiment, through adopting square connecting piece, mainly make things convenient for the reduction space, when fixing the electric wire, can all fill whole hole, prevent that the skew is controlled to the electric wire, it is more real to the crimping of electric wire.

Further, the square connecting piece comprises a square body and a guide piece 1, the square body is fixedly connected with the porcelain joint, at least two threaded holes 2 are formed in the square body, a fixing bolt 3 is arranged in each threaded hole 2, and the guide piece 1 is arranged in the corresponding threaded hole 2;

and a small chamfer is arranged on the lower bottom surface of the rack of the fixing bolt 3.

In this embodiment, the square body is designed into two specifications, the thickness of the fixing bolt 3 is matched with the size of the square hole of the square body, so that the whole square hole basically has no virtual position, the blind plugging effect can be achieved (namely, the metal body can not be deviated or in uneven crimping by any insertion), one is provided with two threaded holes 2, the other is provided with three threaded holes 2, different working conditions can be met, and when only one-way wiring is needed, the scheme of the two threaded holes 2 is adopted; when two paths of the power supply are required to be connected to the power supply at the same time, the scheme of three threaded holes 2 can be adopted; when the scheme of three screw holes 2 is adopted, in order to ensure that the electric wire can be accurately inserted into the corresponding lower part of the fixing bolt 3 and be pressed tightly, the side edge of the screw hole 2 in the middle is designed with the guide sheet 1, the function of the guide sheet 1 is to ensure that the electric wire of the screw hole 2 in the middle can be accurately and reliably inserted into the lower part of the fixing bolt 3, through setting a small chamfer, the square body can not complete the right-angle bending in an ideal state, in fact, when the fixing bolt 3 is screwed, the small chamfer on the bottom surface of the fixing bolt 3 just fits with the bending angle of the square body, and the whole square body adopts a nickel plating process mainly because: the square body needs to be rustproof, and contact resistance can be generated after the square body is rusted, so that the square body is heated abnormally; the ceramic joint is high in use environment temperature, and if nickel plating treatment is not carried out, the square body can be oxidized after a long time.

Further, the porcelain connects including porcelain joint body 4 and spring buckle base 5, and is a plurality of the connecting piece all sets up in the porcelain connects body 4, the porcelain connect body 4 with buckle base is dismantled and is connected.

In this embodiment, through setting up the porcelain connects body 4 and spring buckle base 5, the porcelain connects body 4 can be convenient follow take off or block into on the spring buckle base 5, if need take off when making things convenient for the field installation the porcelain connects body 4, directly take off the porcelain connects body 4 to follow the electric heating coil toollessly the porcelain connects body 4, after having connect the power cord of two sides, will again the porcelain connects body 4 to press back spring buckle base 5.

Further, the square body comprises a hollow frame body 6 and a support plate 7, the support plate 7 and the hollow frame body 6 are integrally formed, and the hollow frame body 6 is fixedly connected with the porcelain connector body 4.

In this embodiment, through setting up extension board 7 with cavity framework 6 for the square top adopts double-deck overlapping, and its main function is the space of thickening top tapping and the intensity of strengthening the top, when preventing big torsion locking, the square body warp.

To sum up, the utility model has the advantages that: 1. by adopting the square connecting piece, the gap is mainly conveniently reduced, when the electric wire is fixed, the whole hole can be completely filled, the electric wire is prevented from being deviated left and right, the electric wire is more firmly pressed, and the risk of sparking is reduced; 2. the wiring can be easily and reliably wired at any angle of installation; 3. the electric wires of the two halves of the electric heating coil can be connected to the same power supply in parallel, extra wire separation is not needed, time is saved, and the electric heating coil is more reliable.
