Abstract
The utility model relates to a pin structure of a double-pole electronic element. The pin structure comprises a first pin and a second pin which are separately arranged at intervals. A first patch base island is arranged on the first pin, and a first lead wire integrated with the first patch base island is arranged on the first patch base island. A second first patch base island is arranged on the second pin, and a second lead wire integrated with the second patch base island is arranged on the second patch base island. A flat-shaped flat section is arranged at the free end of the first lead wire. The pin structure has the advantages of being reasonable in structure, good in radiating effect and the like.
Description
Technical field
The utility model relates to a kind of pin configuration, is specifically related to a kind of pin configuration of bipolar electric sub-element.
Background technology
The pin configuration of existing bipolar electric sub-element is to cooperate bipolar welding electronic elements to use with it by being comprised of spacing the first pin and the second pin arranged apart.When the first pin and the second pin are combined, need to place welding material and bipolar electric sub-element between the first pin and the corresponding paster base of the second pin island, then carry out the welding of bipolar electric sub-element.Described the first pin all becomes cylindric with the corresponding lead-in wire of the second pin, again because the bipolar electric sub-element that is mated is large current bi-pole electronic component (being commonly considered as greater than more than the 3A electric current), this electronic component can produce certain high heat in use, and the poor radiation of existing pin configuration easily causes the bipolar electric sub-element to lose efficacy.
Summary of the invention
The purpose of this utility model is: provide a kind of not only rational in infrastructure, and the pin configuration of the bipolar electric sub-element of good heat dissipation effect, to overcome the deficiencies in the prior art.
In order to achieve the above object, the technical solution of the utility model is: a kind of pin configuration of bipolar electric sub-element includes spacing the first pin arranged apart and the second pin; Described the first pin has the first paster Ji Dao, and the first paster Ji Dao have with its each other one first the lead-in wire; Described the second pin has the second paster Ji Dao, and the second paster Ji Dao have with its each other one second the lead-in wire; And its: described the first lead-in wire free end has a flat part that is flat.
In technique scheme, the free end of described the second lead-in wire clamps heat sink.
In technique scheme, described heat sink has the wiring through hole.
The good effect that the utility model has is: because described the first lead-in wire free end has a flat part that is flat, therefore, increased the area of dissipation of lead-in wire, so that the thermal diffusivity of lead-in wire is improved, avoided the bipolar electric sub-element because the inefficacy that high heat causes has realized the purpose of this utility model.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the cross-sectional schematic of the A-A of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and the embodiment that provides, the utility model is further described, but is not limited to this.
As shown in Figure 1, 2, a kind of pin configuration of bipolar electric sub-element includes spacing the first pin 1 arranged apart and the second pin 2; Described the first pin 1 has the first paster base island 1-1, and the first paster base island 1-1 have with its each other one first the lead-in wire 1-2; Described the second pin 2 has the second paster base island 2-1, and the second paster base island 2-1 have with its each other one second the lead-in wire 2-2; Described the first lead-in wire 1-2 free end has a flat part 1-2-1 who is flat.This flat part not only is conducive to heat radiation, also is convenient to weld, the multiple different assembling mode such as plug-in mounting.
As shown in Figure 1, 2, in order further to improve radiating effect of the present utility model, the free end of described the second lead-in wire 2-2 clamps heat sink 3.
As shown in Figure 1, for the ease of wiring, described heat sink 3 has wiring through hole 3-1.
When the utility model uses, the utility model is welded as a whole by welding material (soldering paste, weld tabs) and bipolar electric sub-element, because the first lead-in wire 1-2 free end has a flat part 1-2-1 who is flat, and second the lead-in wire 2-2 free end clamp heat sink 3, so greatly improved radiating effect of the present utility model.Realized original intention of the present utility model.
