Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.
Shown in Fig. 6-8, in each holding piece of the bread board shell fragment 6 of present embodiment, integral body is provided with a reinforcement 7 on the outside wall surface of the outside wall surface of this preparatory insertion section, the outside wall surface of this fastening part, this fixed part and the outside wall surface of this holding part.The thickness, the thickness, the thickness of reinforcement 72 that is positioned at the outside wall surface section of this fastening part of reinforcement 73 that is positioned at the outside wall surface section of this fixed part of reinforcement 74 that is positioned at the outside wall surface section of this holding part increases successively.The thickness of reinforcement 74 that is positioned at the outside wall surface section of this holding part all increases continuously, and likewise, the thickness, the thickness of reinforcement 73 that is positioned at the outside wall surface section of this fastening part of reinforcement 73 that is positioned at the outside wall surface section of this fixed part also all increases continuously.As shown in Figure 8; Be positioned at the reinforcement 72 of the outside wall surface section of this fastening part; Promptly be positioned at the reinforcement of boost line CC top, only cover the bottom of the outside wall surface of this fastening part, be positioned at the reinforcement 74 of the outside wall surface section of this holding part; I.e. reinforcement 74 between boost line EE and boost line FF only covers the top of the outside wall surface of this holding part.
As shown in Figure 8, in each holding piece, this reinforcement 7 is one-body molded with this holding piece.The reinforcement 72 that is positioned at this fastening part outside wall surface section is an arc, and the reinforcement 73 that is positioned at the outside wall surface section of this fixed part forms a bending angle with the outside wall surface section reinforcement that is positioned at this holding part 74, and the angle of this bending angle is 150 °.As shown in Figure 7, the reinforcement 71 that is positioned at the outside wall surface section of this preparatory insertion section all has an arc-plane with the reinforcement 74 that is positioned at the outside wall surface section of this holding part, and the arc-plane shown in Fig. 6-7 is a semi circular surface.The material of bread board shell fragment 6 and reinforcement 7 is phosphor bronze, and bread board shell fragment 6 is made into the foil shape.
The bread board shell fragment 6 of the band reinforcement shown in Fig. 6-8 is inserted the bread board that the panel body shown in Fig. 1-2 gets final product cost of manufacture embodiment.As shown in Figure 9, in bread board shell fragment 6, the internal face of the fastening part 62 of each holding piece and be formed with a lead patchhole 9 with the internal face of the fastening part 62 of the holding piece of this holding piece mirror image symmetry.
Shown in figure 10, during use, the plastic casing of lead 8 one ends is peeled off and makes wire stylet 81 expose.This end with lead 8 inserts in the formed jack 4 of holding piece of two mirror image symmetries then.Because the material of reinforcement 7 and bread board shell fragment 6 is phosphor bronze; And the phosphor bronze material has ductility, fatigue resistance, corrosion resistance and elasticity preferably; The reinforcement 72 of this fastening part outside wall surface section is an arc in addition, and therefore the reinforcement 72 of the fastening part outside wall surface section of two mirror image symmetries has increased the dynamics of bread board shell fragment clamping wire stylet.The elastic performance, rigid nature that has greatly improved this bread board shell fragment 6 with the conduction property that contacts of lead.In like manner, be positioned at integral rigidity and elasticity that bending angle that reinforcement 73 and the outside wall surface section reinforcement that is positioned at this holding part 74 of the outside wall surface section of this fixed part form has not only increased bread board shell fragment 6, the reliability that has also promoted conducting with increase the service life.Because the reinforcement 7 on each holding piece outside wall surface protrudes from outside wall surface, therefore increased the contact area with the plastic cement spacing block, the firm performance that therefore connects is improved.Shown in Fig. 6-7, because reinforcement 7 protrudes from outside wall surface, and be the reinforcement that two ends all have a semicircle arc-plane, the profile of bread board shell fragment 6 that therefore contains this reinforcement 7 is more attractive in appearance.
Though more than described the embodiment of the utility model, it will be understood by those of skill in the art that these only illustrate, the protection range of the utility model is limited appended claims.Those skilled in the art can make numerous variations or modification to these execution modes under the prerequisite of principle that does not deviate from the utility model and essence, but these changes and modification all fall into the protection range of the utility model.
