Abstract

PURPOSE: A punching shape of a shape memory alloy wire of a retractable antenna is provided to improve tensile intensity of the shape memory alloy wire and top. CONSTITUTION: A shape memory alloy wire of a retractable antenna is punched at its top, bottom, right and left such that the punching shape of the shape memory alloy wire has a center and four blades. This punching shape makes contact surface and friction area between the shape memory allow wire and top increased so as to increase tensile intensity of the shape memory allow wire and top. That is, this punching shape increases tensile intensity of the shape memory alloy wire and top from conventional 5 Kg/f to 12 Kg/f. In addition, tensile intensity after the shape memory alloy wire is placed in a humidity chamber for an hour is improved from 2 Kg/f to 6.5 Kg/f so that quality badness due to tensile intensity badness is prevented.

Description

리트렉터블안테나의 기억형상합금 와이어의 펀칭 형상{PUNCH APPEARANCE OF PUNCH APPEARANCE OF N.T WIRE THE ROAD ANTENNA}Punching shape of memory shape alloy wire of retractable antenna {PUNCH APPEARANCE OF PUNCH APPEARANCE OF N.T WIRE THE ROAD ANTENNA}

본 발명은 무선기기에서 리트렉터블안테나의 기억형상합금 WIRE와 TOP의 사출성형공정에 앞서서 기억형상합금 WIRE 표면에 PUNCHING함에 있어서 종래의 방법은(도1) 기억형상합금 WIRE에 PUNCHING을 앞,뒤에서 PUNCHIGN함으로써 기억형상합금 WIRE와 TOP의 인장강도는 평시 5Kg/f정도 나오고 있으며(하절기 3~4Kg/f),항습조에서 1시간후 인강강도 TEST시 2Kg/f이 나오고 있다.In the present invention, prior to the injection molding process of the memory shape alloy WIRE and TOP of the retractable antenna in a wireless device, the conventional method (PIC 1) performs the punching on the memory shape alloy WIRE before and after. By PUNCHIGN, the tensile strength of memory alloy wire and TOP is about 5Kg / f in summer (3 ~ 4Kg / f in summer), and 2Kg / f in TEST after 1 hour in humidity chamber.

본 발명은 이와같은 종래의 문제점을 해결하기 위하여 안출한 것으로, 본 발명의 목적은, 리트렉터블 안테나의 기억형상합금 WIRE의 PUNCHING 형상를 개선하여기억형상합금 WIRE와 TOP의 인장강도를 향상함이 본 발명의 기술적 과제이다.The present invention has been made to solve such a conventional problem, and an object of the present invention is to improve the tensile strength of the memory alloy alloy WIRE and TOP by improving the punching shape of the memory alloy alloy of the retractable antenna. Technical problem of the invention.

도2a : 개선후의 기억형상합금 WIRE의 PUNCHIGN 형상도Fig. 2a: PUNCHIGN shape diagram of memory shape alloy wire after improvement

이와같은 목적을 달성하기 위한 본 발명은 기억형상합금 WIRE의 PUNCHING 형상에 관한 것으로 , 본 발명의 실시예를 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다.The present invention for achieving the above object relates to the shape of the PUNCHING of the memory shape alloy WIRE, it will be described in detail with reference to the accompanying drawings an embodiment of the present invention.

PUNCHING 형상을 종래의 앞,뒤 PUNCHING(도1a)에서 상하좌우에서 PUNCHING함으로써(도2a) 기억형상합금 WIRE와 TOP의 접촉면및 마찰부위가 상승함으로써 기억형상합금 WIRE와 TOP의 인강강도함이 본 발명의 구성이다.By punching the punching shape up, down, left, and right in the conventional front and rear punching (FIG. 1A) (FIG. 2A), the contact surface and the frictional part of the memory shape alloy WIRE and TOP are raised to increase the toughness of the memory shape alloy WIRE and TOP. It is the composition.

이상에서 설명한 바와같은 본 발명은 리트렉트블안테나의 기억형상합금 WIRE의 PUNCHING 형상을 개선하여 기억형상합금 WIRE와 TOP의 인장강도를 향상시켜 종래의 PUNCHING 형상보다 인장강도가 5Kg/f → 12Kg/f 향상됨과 동시에 항습조에서 1시간후 인장강도 TEST시의 2Kg/f → 6.5Kg/f 향상되어 기억형상합금 WIRE와 TOP의 인장강도 불량으로 인한 품질 불량 방지가 본 발명의 효과라 할 수있다.As described above, the present invention improves the PUNCHING shape of the memory shape alloy WIRE of the retractable antenna to improve the tensile strength of the memory shape alloy WIRE and TOP, so that the tensile strength is 5Kg / f → 12Kg / f. At the same time, the improvement of 2Kg / f → 6.5Kg / f at the time of tensile strength test after 1 hour in the humidity chamber prevents the poor quality due to the poor tensile strength of the memory alloy alloy wire and the TOP.
