One mounting surface it is parallel, between the groove bottom and one mounting surface in described two mounting surfaces it is vertical away from
From for L2, and 0.30mm≤L2≤0.35mm.
The needle core is made of phosphor bronze.
Described two mounting surfaces are arranged in parallel, and the vertical range between described two mounting surfaces is 3.2mm.
The side of the ontology is made of leading flank, trailing flank, left side and right side, two mounting surfaces of the ontology
Respectively top and bottom, the recess portion are set to the bottom surface, and the recess portion penetrates through the leading flank and trailing flank.
The needle stand is applied to air conditioner.
The utility model also provides a kind of household electrical appliance, including needle stand described above.
The utility model penetrates through the side of ontology due to recess portion, and the recess portion on ontology forms air flow channel, and needle core passes through
Recess portion, during Wave crest Welding, the mounting surface that needle stand is equipped with recess portion is attached on pcb board, and the heat of generation can pass through recess portion
It distributes, heat is avoided to be transmitted to ontology by needle core, and then reduce ontology and occur melting risk after wave-soldering, to drop
There is the problem of long and short hands in low needle core.
Detailed description of the invention
Fig. 1 is the construction profile of needle stand in the utility model embodiment.
Fig. 2 is the bottom surface structure figure of needle stand in the utility model embodiment.
Specific embodiment
As depicted in figs. 1 and 2, the needle stand proposed in the utility model embodiment, the needle stand are applied in household electrical appliance, example
Such as air conditioner, refrigerator.The needle stand includes ontology 10 and the needle core 20 that is mounted on ontology 10, and ontology 10 includes spaced
The side of two mounting surfaces of two mounting surfaces and connection, one end of needle core 20 are stretched out from one of mounting surface, needle core 20 it is another
One end is stretched out from another mounting surface, and a mounting surface in two mounting surfaces is equipped with the recess portion of perforation side, and needle core
Across recess portion.Due to the side of recess portion perforation ontology, the recess portion on ontology forms air flow channel, and needle core passes through recess portion, wave crest
It welding in welding process, the mounting surface that needle stand is equipped with recess portion is attached on pcb board, and the heat of generation can be distributed by recess portion,
It avoids heat from being transmitted to ontology by needle core, and then reduces ontology and occur the risk melted after wave-soldering, to reduce needle core
There is the problem of long and short hands.
Recess portion is that a mounting surface in two mounting surfaces is recessed inwardly the groove 17 to be formed.
In the present embodiment, ontology 10 is in cuboid, and side is by leading flank 11, trailing flank 12, left side 13 and right side 14
Composition, two mounting surfaces are parallel, and two mounting surfaces are respectively top surface 15 and bottom surface 16, and the upper end of needle core 20 is stretched out from top surface 15,
The lower end of needle core 20 is stretched out from bottom surface 16.During Wave crest Welding, bottom surface 16 is contacted with pcb board, groove 17 from bottom surface 16 to
Sunken inside is formed, and groove 17 penetrates through leading flank 11 and trailing flank 12(, that is, groove and extends along the width direction of ontology).
20 quantity of needle core is ten, and ten needle cores 20 are divided into five groups of needle core groups, and every group of needle core group includes two needle cores, this
Five groups of needle core groups are arranged successively along the length direction of ontology, and two needle cores in every group of needle core group are arranged along the width direction of ontology
Column.Number of recesses is five, and five grooves are arranged in parallel along the length direction of ontology, the corresponding one group of needle core group of each groove, often
Two needle cores in group needle core group both pass through groove.
Since 10 are provided with recess portion on the body, the stability that can be installed on ontology to needle core is had an impact, therefore is
Guarantee that needle core is installed to the stability on ontology, while increasing the heat resistance of ontology, by the enlarged in thickness of ontology 10.This implementation
In example, ontology 10 with a thickness of L3, L3=3.2mm(in the prior art ontology with a thickness of 2.5mm), i.e. top surface 15 and bottom surface 16
Between vertical range be 3.2mm.
Groove 17 have groove bottom and two slot sides disposed in parallel, groove bottom is parallel with top surface, bottom surface, slot side and
Groove bottom is vertical, and the vertical range between two slot sides is L1, and 0.6mm≤L1≤0.8mm, the i.e. width of groove are
0.6mm to 0.8mm, preferably L1=0.7mm.Vertical range between groove bottom and bottom surface 16 is L2, and 0.30mm≤L2≤
0.35mm, the i.e. depth of groove are 0.30mm to 0.35mm.
Melt risk to further decrease ontology, needle core is made of phosphor bronze, is used for brass relative to existing
The poor thermal conductivity of phosphor bronze reduces the heat for being transmitted to ontology.
