Embodiment

The elastic arm 30 refer to shown in Fig. 1 to Fig. 6, the utility model antenna connects tightening part 20 that shell fragment comprises plate-like base 10, extends to form from described plate-like base 10 rear end inverse bending, upwards extending to form from described tightening part 20 end tilts and the support sector 40 extended to form towards described plate-like base 10 from described elastic arm 30 end inverse bending.Defining described tightening part 20 one end is rear end, and opposition side is front end.

The appearance molten tin bath 11 upwards caved in is formed between described plate-like base 10 and described tightening part 20.Described elastic arm 30 comprises and is parallel to from described tightening part 20 end horizontal part 31 that described plate-like base 10 extends to form, be inclined upwardly from described horizontal part 31 end the contact site 33 extending to form rake 32 and be formed at described rake 32 top.

Described support sector 40 extends to form towards described plate-like base 10 direction after described contact site 33 inverse bending, comprises extension 41, the abutting part 42 abutting described plate-like base 10 under described elastic arm 30 pressed status that described extension 41 ends bent is formed and at the blocking arm 43 laterally extended to form to both sides between described extension 41 and described abutting part 42.

The both lateral sides of described plate-like base 10 upwards bending has extended to form screening glass 50, and described screening glass 50 comprises front screening glass 51 and rear screening glass 52.Described front screening glass 51 protects front end contact site 33 part of described elastic arm 30 not damaged by pressure, and described rear screening glass 52 protects the horizontal part 31 of described elastic arm 30 not damaged by pressure, and described front screening glass 51 is in same level with the top of described rear screening glass 52.

Blocking arm 43 position of the corresponding described support sector 40 of described plate-like base 10 both lateral sides is provided with catch 60, described catch 60 comprise inwardly extend to form mutually again after described plate-like base 10 both lateral sides upwards extends be positioned at upper stop piece 61 above described blocking arm 43 and catch 62 from described upper stop piece 61 front end bending downward vertically and before extending to form.The horizontal level at described upper stop piece 61 top is lower than the horizontal level at described screening glass 60 top.

Need there is certain space to carry out elastic deformation for described elastic arm 30 at longitudinal direction below the front end of described elastic arm 30; and the blocking arm 43 of described support sector 40 and the abutting portion of described catch 60 need the arm of force that could reduce vertical direction closer to front end, reach protection elastic arm 30 under normal circumstances not by the object of damage.

Please consult shown in Fig. 4, Fig. 6 by emphasis; when described elastic arm 30 be pressed down be in crimped status time; the abutting part 42 of described support sector 40 contacts with described plate-like base 10 and produces elastic anchorage force downwards; described forward and backward screening glass 51,52 protects the front end contact site 33 of described elastic arm 30 and described elastic arm 30 rear end horizontal part 31 not to be damaged by excessive compression respectively.

When described elastic arm 30 is twitched by antenna feed point; described elastic arm 30 will produce the power F of incline direction in described contact site 33 position; the blocking arm 43 of described support sector 40 will move to the bending place between described upper stop piece 61 and described lower stop piece 62 obliquely simultaneously; even if described blocking arm 43 is as far as possible forward to the front end of described upper stop piece 61, described front catch 62 then protects described blocking arm 43 to be unlikely to skid off from the front end of described upper stop piece 61.Now, the power F suffered by described elastic arm 30 is decomposed into power F1 in the vertical direction, and the arm of force in vertical direction is h1, and the arm of force reaches the shortest.In proof procedure, described catch 60 as without as described in the existence of front catch 62, blocking arm 43 then in described support sector 40 still needs to move to the back-end, described blocking arm 43 need be made to move up after, the centre position that can remain on described upper stop piece 61 is just unlikely to cause that described blocking arm 43 is stressed to be skidded off, and this undoubtedly can the lengthen vertical arm of force, even if easily cause described elastic arm 30 under low-force amount to produce the consequence of mechanical deformation.

The utility model antenna connects shell fragment by arranging the blocking arm 43 laterally extended to both sides in described support sector 40 lower end, again by described plate-like base 10 be positioned at described blocking arm 43 position upwards bending extend to form the catch 60 be positioned at above described blocking arm 43, simultaneously, described catch also comprises and prevents described blocking arm 43 forward movement with catch before anti-skidding 62, make the contact fulcrum of described blocking arm 43 and described catch 60 closer to front end, the arm of force is reduced, makes described elastic arm 30 be not easy to damaged.
