Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
Embodiment 1:
Please refer to shown in Fig. 1 to 3, the present embodiment provides a kind of junction blocks, mainly include split type pedestal 1 and gland 2,
It is provided with several inserted slots 11 on pedestal 1, the present embodiment is provided with first in each inserted slot 11 with three 11 examples of inserted slot
Pin, i.e. external terminal are formed on sheet metal 3, the bottom that the first sheet metal 3 is pierced by junction block.
Close to corresponding three the first sheet metals 3 setting in the side of pedestal 1, there are three pressure head 21,21 gaps of pressure head on gland 2
Ground is located at the side of the first sheet metal 3, and the second sheet metal 4, corresponding pressure on pedestal 1 are arranged between pressure head 21 and the first sheet metal 3
First 21 offer recessing groove 12, offer limiting slot 13 on pedestal 1 between recessing groove 12 and inserted slot 11, limiting slot 13 with
It is provided with limited step 14 between inserted slot 11, in the bottom insertion limiting slot 13 of the second sheet metal 4, the first sheet metal 3 and the
Grafting gap, the second sheet metal 4 and 21 abutting contact of pressure head are formed between two sheet metals 4, the top of the second sheet metal 4 is by pressure head
21 extruding force is biased against to the first sheet metal 3, is realized and is pressed from both sides to the joint outer part between the first sheet metal 3 and the second sheet metal 4
Tight purpose.Wherein the first sheet metal 3 is the contact of primary conductive connection, and the second sheet metal 4 is mainly for raising pressure head 21
Intensity, avoid pressure head 21 from directly contacting with joint outer part and wear, aging even fail.
Grafting gap is corresponded on pedestal 1 offers grafting notch 15 for being inserted into joint outer part, optimally, inserting groove
