Abstract
The utility model discloses a GSM antenna shrapnel, which comprises antenna shrapnel heads, a retaining bone, a main board, clamps, a shrapnel, a heat stake and a bracket. The shrapnel is connected onto the bracket through hot melting. The left end of the shrapnel is provided with two shrapnel heads and the two shrapnel heads are the same with each other in shape. The two sides of the shrapnel heads are provided with clamps and the clamps are welded onto the bracket in an L shape. The bracket is additionally provided with the retaining bone. The retaining bone is arranged on the left side of the shrapnel heads. Due to the design of the above structural arrangement, the problem in the prior art that the offset contacts of the base pins of shrapnel heads are out of the range of feed points due to the limitation on the machining accuracy of antenna shrapnel heads so as to cause the poor contact effect of the base pins can be solved.
Description
Technical field
The utility model relates to a kind of GSM antenna shrapnel.
Background technology
At present, GSM antenna shrapnel is for various electronic products.GSM antenna shrapnel comprises support and be located at the shell fragment on support, and support is fixed on body.Most shell fragment head manufactures instead " C " shape, rack-mount as contact point passes through hot molten column taking bracket leg support point and mainboard fulcrum, but due in the process of manufacture shell fragment head, the angle of inner turnover is wayward, thereby have influence on contacting of shell fragment head tube pin and base plate, easily cause contact point to exceed feedback point range or loose contact.
Summary of the invention
The utility model example provides a kind of GSM antenna shrapnel, and it can make contact well be controlled at feedback point range, avoids loose contact, has solved antenna shrapnel due to the unstable loose contact problem causing in the unstable contact of pin.
A kind of GSM antenna shrapnel, comprises support and shell fragment, and described shell fragment is installed on described support by hot molten column, and described shell fragment left end is provided with two shell fragment heads that shape is identical.
As further improvement of the utility model, described shell fragment head is processed into " √ " shape, and production precision is high, and angle is easy to control.
As further improvement of the utility model, described shell fragment head both sides are provided with clamper, described clamper with " L " shape welds on described support, described clamper bottom is provided with catch.
As further improvement of the utility model, on described support, set up gear bone, described gear bone is arranged in the left side brackets of shell fragment head.
The beneficial effects of the utility model are to have solved antenna flicking head to cause shell fragment head tube pin skew contact to exceed the loose contact problem that feedback point range causes because production and processing accuracy is restricted.Shell fragment head of the present utility model both sides set up clamper and gear bone is set up in left side, not only can improve consistency but also the restriction shell fragment head tube pin deviation range of contact position, have greatly improved the stability of contact and the contact performance of shell fragment head and mainboard.
Brief description of the drawings
Fig. 1 is the front view of a kind of GSM antenna shrapnel of the utility model;
Fig. 2 is the vertical view of the utility model antenna flicking head displacement field.
In figure, 1 is shell fragment head, and 2 is support, and 3 is gear bone, and 4 is mainboard, and 5 is clamper, and 6 is shell fragment, and 7 is hot molten column, and 8 is clamper bottom catch.
Embodiment
Accompanying drawings and embodiment further illustrate the utility model.
As depicted in figs. 1 and 2, a kind of GSM antenna shrapnel, comprise support 2 and shell fragment 6, described support 2 is provided with the hot molten column 7 of protrusion, described antenna shrapnel 6 is installed on described support 2 by hot molten column 7, described shell fragment 6 left ends are provided with two shell fragment heads 1 that shape is identical, and described shell fragment head is processed into " √ " shape.Described support 2 is the U-shaped support of integral type, and mainboard 4 is positioned at described left side brackets below.
Described shell fragment head 1 bilateral symmetry is provided with two L-type clampers 5, and described clamper 5 bottoms are provided with the catch 8 for limiting the displacement to the right of shell fragment head, thus maximum displacement when restriction shell fragment head moves right.
Described shell fragment head 1 opposite frame bottom is provided with and limits the shell fragment head gear bone 3 to left dislocation, thus maximum displacement when described gear bone 3 defines shell fragment head and is moved to the left by contacting with the top of shell fragment head bent area.
Can avoid the linear contact of shell fragment head and mainboard to exceed feedback point range by L-type clamper and gear bone, and displacement is controlled within the scope of 0.1mm.
