Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in Figure 7, the embodiment of the present invention comprises the equipment connection block 1, outlet contiguous block 2, clamping block 3 and the bolt 4 that are copper material.Equipment connection block 1, outlet contiguous block 2, clamping block 3 material are identical, electrochemical reaction can not occur each other.
Specifically, as shown in Figure 1 and Figure 2, equipment connection block 1 is in rectangular-shaped, upper surface is provided with the first cable connections 11 for connection device cable, lower surface is provided with opening 101, and opening 101 extends to form a cavity 100 to the inside of equipment connection block 1, and outlet contiguous block 2 enters in cavity 100 from opening 101 and also embeds closely in cavity 100, also namely, the sidewall close contact as much as possible of outlet contiguous block 2 and cavity.The upper surface of equipment connection block 1 is provided with elongated hole 10 along the length direction of equipment connection block 1, and elongated hole 10 is communicated with cavity 100 and corresponding with the through hole about 20 on outlet contiguous block 2, so that the low pressure mouthpiece 51 of transformer 5 passes.
As shown in Figure 3, Figure 4, outlet contiguous block 2 is in rectangular-shaped, and central area is provided with circular for being set in the through hole 20 on transformer low voltage mouthpiece 51.
As shown in Fig. 5, Fig. 6, Fig. 7, clamping block 3 embeds in cavity 100, and between outlet contiguous block 2 and the rear wall 12 of cavity 100.
As shown in Fig. 2, Fig. 7, the rear wall 12 of cavity 100 is provided with screwed hole 120, and bolt 4 is supported on clamping block 3, clamping block 3, outlet contiguous block 2 to be closely fixed in cavity 100 through screwed hole 120.
Again as shown in Figure 3, Figure 4, in order to make, position between outlet contiguous block 2 and cavity 100 is more stable, contact area is larger, and the front end upper surface of outlet contiguous block 2, lower surface are inclined plane 21, and this is wedge shape with regard to making the front end of outlet contiguous block 2.As shown in Figure 2, the front portion of cavity 100 is a wedge-shaped slot 102, and the shape of the front end of outlet contiguous block 2 and the shape of wedge-shaped slot 102 are coincide, and insert closely in this wedge-shaped slot 102.
In the present embodiment, the two sides of cavity 100 are Open architecture, cavity 100 is extended in one end of clamping block 3, as shown in Figure 5, Figure 6, the position that clamping block 3 extends cavity 100 is provided with the second cable connections 31, like this, clamping block 3 also can be connected with an equipment cable etc., when the first cable connections of equipment connection block 1 be damaged, need to connect more equipment cable or electric current excessive and the sectional area of the first cable connections cannot be increased time, the second cable connections 31 also may be used for connection cable.
As shown in Figure 5, Figure 6, in order to increase contact area, the connective stability between clamping block 3 and outlet contiguous block 2, the leading flank of clamping block 3 is provided with a raised line 32.As shown in Figure 3, Figure 4, the trailing flank of outlet contiguous block 2 is provided with a groove 22.As Fig. 7, raised line 32 embeds in groove 22.Further, the width L1 of clamping block 3 and the width L2 sum of outlet contiguous block 2 equal the width L3 of cavity 100, so, after clamping block 3, outlet contiguous block 2 embed cavity 100, large and tight with the madial wall contact area of cavity 100.
The present embodiment, when assembling, can adopt following steps:
First outlet contiguous block 2 is embedded in cavity 100 by opening 101, by the low pressure mouthpiece of transformer 5 through through hole 20, elongated hole 10, the advantage of elongated hole 10 is: when the machining accuracy of equipment connection block 1, outlet contiguous block 2 is not high, and following low pressure mouthpiece 51 can carry out suitable position adjustment along elongated hole 10.
Then, the side of clamping block 3 from cavity 100 is inserted, and raised line 32 is inserted in groove 22, after treating that clamping block 3 inserts cavity 100, be screwed into screwed hole 120 with bolt 4, bolt 4 is supported tightly on clamping block 3.
Finally, with the nut 52 on low pressure mouthpiece 51, equipment connection block 1 etc. is fixed on the low pressure mouthpiece 51 of transformer.
To sum up, the present invention is while avoiding that electrochemical reaction occurs, add contact area, and employing embedded design, annexation between each parts, position relationship are highly stable, even if when running into external mechanical force, also can keep comparatively stable structure, avoiding the loose contact deforming and cause.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
