Specific embodiment
With reference to the accompanying drawings, according to the present invention, the embodiment of electric contact piece 1 includes two bullets with least one bending point 12
Property arm 11, each elastic arm are formed with the numerical value between 90 ° and 180 ° between two ends of above-mentioned elastic arm 11
Angle " α ", also, elastic arm 11 extended in corresponding contact wall 9 in turn, and each contact wall 9 has edge, and the edge is in the company for the treatment of
Engagement edge 10 is constituted on the electric conductor 8 for connecing.
Elastic arm 11 is partly linked together by substrate 14, and the elongated shape of the substrate up to contacts the height of wall 9
Degree, without being linked to the contact wall 9.
Contact wall 9 is set, a certain angle " β " being formed between 0 ° and 180 °, and the angle is with regard to electric conductor to be connected
Direction of insertion be re-entrant angle.Additionally, the lower part of the contact wall 9 in the region that wherein substrate 14 is set relatively is on corresponding contact side
It is rounded on the direction of edge 10, to contribute to that electric conductor 8 is incorporated between the engagement edge 10 at an acute angle.
Put into practice in case the electric conductor 8 with its insulation sleeve 8a is introduced into, electric contact piece 1 is positioned in its housing 2
In inside, the housing has lateral openings 3, wherein, cable locators 4 pass through its laterally projecting portion 5 and rotation axiss are set
Put.Localizer 4 has two circular holes：Circular hole 7a in circular hole 6a on its front portion 6 and behind portion 7, wherein, electric conductor 8
End by accommodating to implement the motion that is rotatably connected.
Once electric conductor 8 is introduced in localizer 4, both just proceed by rotary motion, as in accompanying drawing, institute is continuous
What ground was represented, so that electric conductor 8 to be connected to the inner side of electric contact piece 1.
In order to promote electric conductor 8 to be introduced in electric contact piece 1, electric conductor 8 is entered into by contacting the border circular areas of wall 9
In electric contact piece 1, contact wall 9 guides electric conductor towards engagement edge 10.May go out in order to avoid contacting wall 9 in a rotational direction
Existing bending, effect of the substrate as the block for the contact wall 9.
During rotary motion, once electric conductor 8 is contacted with cut edge 10, these just start the insulation sleeve of electric conductor 8
The otch 15 of 8a, meanwhile, according to this, contact unit and the elastic arm being arranged between bending point 12 and contact wall 9 that wall 9 is formed
11 part obtains the extension a of otch 15 by bend open.
Once engagement edge 10 reaches core 8b of electric conductor 8, contact wall 9 itself is increased and is cut also by bend open
The extension operating member a of mouth 15.
Once rotary motion is completed, the bending accumulated in elastic arm 11 is ensured that and for engagement edge 10 to be fixed on electric conductor
In 8 core 8b, also, the extension a of the otch for obtaining during rotation ensures the possible thin film of rupture insulation sleeve 8a, so as to
Avoid due to the erroneous contacts caused by the thin dielectric membrane.
In embodiment is put into practice, wherein, electric conductor 8 is introduced in electric contact piece using its end for being stripped protective jacket 8a
In 1, represented by the order illustrated in as Figure 15 to 18, on the one hand, the presence of localizer 4 or substrate 14 is unnecessary
, also, still further aspect, via contact wall 9 and the re-entrant angle β in the direction of insertion of electric conductor 8, electric conductor 8 is in contact wall 9
On the insert action of itself by the elasticity that contacts the unit that formed of wall 9 and be arranged between bending point 12 and contact wall 9
The bending of the part of arm 11 causes to open.Once electric conductor is connected, the bending being accumulated in elastic arm 11 is ensured that and will be contacted
Edge 10 is fixed in core 8b of electric conductor 8.
After the purpose of the present invention has been adequately described, it must further be noted that any of size, shape and outward appearance changes
Become and the material put into practice used in embodiment of referenced electric contact piece 1 change its essence in no instance,
Which is summarized in following claims.
