Description

—种两槽中心导体精密定心收口夹具 - two kinds of precision of the centering slot center conductor clamp shut

技术领域 FIELD

[0001] 本发明属于微波同轴传输线制作技术领域,尤其涉及的是一种两槽中心导体精密定心收口夹具。 [0001] The present invention belongs to the technical field of microwave coaxial transmission line, more particularly, to a two-conductor is the central groove of the centering precision clamp shut.

背景技术 Background technique

[0002] 微波信号传输通路的中心导体一般分为阳头中心导体和阴头中心导体(即开槽中心导体),随着技术的不断发展,测试信号频率不断提高,要求连接器中的中心导体尺寸越来越小,精度要求也越来越高,设计中更多采用了中心导体开两槽的设计方案,而两槽中心导体的收口与定型工艺是实现高性能中心导体的关键技术,导体的收口精度、同轴度和对称度直接影响到产品的核心性能指标。 [0002] The center conductor of the microwave signal transmission path is generally divided into the male and female center conductor center conductor (i.e. slotted center conductor), along with the development of technology, the test signal increasing frequency requirements of the central conductor connector smaller size, higher and higher precision, the design uses a more open design of the center conductor of the two grooves, and the setting process shut two grooves central conductor is a key technology for high performance center conductor, the conductor the shut accuracy, concentricity and symmetry to the core directly affect product performance.

[0003] 现有两槽阴头中心导体的收口工艺,大多采用的是手工收口的方式,即操作人员用镊子、钢丝等工具直接作用于两槽中心导体使其变形达到收口,然后将零件置于热处理设备中进行时效强化定型。 [0003] Process cuff female center conductor of the prior two slots, is mostly used in the manual shut manner, i.e. the tool operator acts directly with forceps, and so deform the central wire conductor reaches two grooves shut, then the part opposite strengthen stereotypes in aging heat treatment equipment.

[0004] 现有的利用模具进行开槽中心导体收口定型的技术方案中,将开槽中心导体直接压入锥形孔操作。 [0004] using the conventional center conductor slotted mold shut stereotypes aspect, the center conductor slotted directly into the tapered hole operations. 但现有方案对两槽中心导体收口定型并不适用,因为收口后的两槽阴头中心导体截面外形和孔瓣围成的形状并不是规则图形,既不同于圆形也不同于椭圆,因此如何实现对两槽阴头中心导体的定心收口,现有方案锥形孔模具就显得无能为力,既不能保证定心,也不能对收口外形有准确的定型。 However, the existing scheme two grooves shaped center conductor cuffs does not apply, because the female center conductor sectional shape and two grooves after the shut valve hole shape surrounded not regular pattern, different from the circular shape is also different from the ellipse, and therefore how to achieve the centering of the two grooves cuff female center conductor of existing programs tapered bore die becomes powerless, can not guarantee the centering, we can not have an accurate profile shape of the cuffs.
