Description
Technical field
The present invention relates to field of air conditioning, more particularly to a kind of needle stand and use the air conditioner of the needle stand.
Background technique
Needle stand (i.e. jumper cap) is with small in size, needle core is more, vdiverse in function, cheap and difference is short-circuit after conducting
The features such as realizing different functionalities is widely used in air-conditioning products.Needle stand used in air-conditioning products is by moulding and needle core group
At needle core is according to certain assembled in sequence in moulding, and moulding is stretched out at the both ends of needle core, and one end of needle core is inserted into pcb board
On, and welded by wave-soldering, the other end of needle core is inserted in using jumper cap realizes different cap serial numbers (i.e. on needle stand
It by different location short circuit, realizes different function, air-conditioning is made to run well).Since needle stand bottom surface is plane, without any air-flow
Channel, it is very close to each other between needle stand bottom surface and pcb board, it is seamless contact, the heat generated during Wave crest Welding can focus
Around solder joint and needle stand, since needle core is made of brass material, thermal conductivity is good, and heat can be transmitted to injection molding by needle core
Part causes moulding to occur melting phenomenon after wave-soldering, and needle core long and short hands problem occurs due to heating power and gravity.
Summary of the invention
To solve the problems, such as that needle stand will appear long and short hands in the prior art, the present invention provides a kind of needle stand and air conditioner.
The technical solution of the present invention is as follows: a kind of needle stand, the needle core including ontology and installation on the body, the ontology
Side including two mounting surfaces of spaced two mounting surfaces and connection, one end of the needle core is from one of mounting surface
It stretches out, the other end of the needle core is stretched out from another mounting surface, and a mounting surface in described two mounting surfaces is equipped with
The recess portion of the side is penetrated through, and the needle core passes through the recess portion.
The recess portion is that one mounting surface in described two mounting surfaces is recessed inwardly the groove to be formed.
The groove has groove bottom and two slot sides disposed in parallel, the vertical range between described two slot sides
For L1, and 0.6mm≤L1≤0.8mm.
L1=the 0.7mm.
The groove has groove bottom and a two slot sides disposed in parallel, in the groove bottom and described two mounting surfaces
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 present invention also provides a kind of household electrical appliance, including needle stand described above.
The present invention 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 be given out by recess portion
It goes, heat is avoided to be transmitted to ontology by needle core, and then reduce ontology and occur melting risk after wave-soldering, to reduce needle core
There is the problem of long and short hands.
Detailed description of the invention
Fig. 1 is the construction profile of needle stand in the embodiment of the present invention.
Fig. 2 is the bottom surface structure figure of needle stand in the embodiment of the present invention.
Specific embodiment
As depicted in figs. 1 and 2, the needle stand proposed in the embodiment of the present invention, the needle stand are applied in household electrical appliance, such as empty
Adjust device, refrigerator etc..The needle stand includes ontology 10 and the needle core 20 that is mounted on ontology 10, and ontology 10 includes spaced two
The side of two mounting surfaces of mounting surface and connection, one end of needle core 20 are stretched out from one of mounting surface, the other end of needle core 20
It is stretched out from another mounting surface, a mounting surface in two mounting surfaces is equipped with the recess portion of perforation side, and needle core passes through
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-soldering weldering
In termination 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, be avoided
Heat is transmitted to ontology by needle core, and then reduces ontology and occur the risk melted after wave-soldering, to reduce needle core appearance
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.
During wave-soldering, wave soldering machine welding temperature be 265-275 degree, weld interval as far as possible less than 5 seconds, after welding
Using air-cooled or extension wire body natural cooling.
The present invention also provides a kind of air conditioners, including above-mentioned needle stand.
Above specific embodiment is only to the design illustrated the present invention, and those skilled in the art are in this hair
Various deformation and variation can be made under bright design, these deformations and variation are included within protection scope of the present invention.
