Description

Terminal unit intenna clip "

The present invention relates to a multi-functional intenna clip for a terminal, and more particularly, to a multi-functional intenna clip for a terminal, and more particularly, to a multi-function intenna clip for a terminal which has a structure for preventing a self-deforming phenomenon even when an external bending stress And more particularly, to a multi-functional intenna clip for a new terminal.

2. Description of the Related Art Generally, an antenna for transmitting and receiving signals is required for a mobile communication terminal that transmits and receives voice, text, and data through wireless communication such as a cellular phone, a PCS, and a PDA. An external antenna such as a helical antenna or a dipole antenna is used . In the case of such an external antenna, since the external antenna protrudes to the outside of the terminal, the electromagnetic waves generated during the operation of the terminal adversely affect the user's body, are easily damaged by external impact during use, .

Accordingly, in recent years, research and development on an intenna, which is an internal antenna provided inside a terminal, has been progressing actively due to the harmful effects of electromagnetic waves and the compactness of cellular phones, and its use is also increasing .

Meanwhile, in order to connect the intenna for a mobile communication terminal to a PCB, a clip which is an intenna contact device which is separately manufactured is interposed. That is, a clip for contact of the intenna is interposed between the intenna and the PCB of the mobile communication terminal (such as a cellular phone). The clip is formed in a substantially C shape to have an elastic force, and the lower portion of the clip is soldered to the PCB. And the upper bent portion is configured to elastically contact the intenna. In general, in the case of a cellular phone, the intenna is attached to the cover on the rear side, the clip is soldered to the PCB built in the cellular phone body, and the cover is connected to the back surface of the cellular phone body to prevent the intenna from interfering with the PC And thus transmits and receives signals to the cellular phone through the intenna. In addition to the mobile phone, most of the other mobile communication terminals transmit and receive signals through the intenna.

However, when the clip, which is a contact medium for signal transmission between the intenna and the PCB, is subjected to permanent deformation due to unreasonable external force generated when the rear cover is coupled to the terminal or external impact caused by dropping the terminal, There is a problem in that signal transmission and reception can not be properly performed to the terminal when the clip for intenna, which serves as a contact medium between the intenna and the internal circuit of the mobile phone (i.e., between the intenna and the PCB) is permanently deformed. The clip for the intenna is made of a metal having self-elasticity and has a structure in which a lower clip portion and an upper clip portion are formed with respect to an intermediate bending portion. The lower clip portion of the clip is soldered to the PCB and the upper clip portion has its own elasticity In particular, the bending portion between the lower soldered portion of the clip and the portion to be in contact with the intenna is permanently deformed by the external force. If the bending portion of the clip is permanently deformed as described above, the contact between the intenna and the clip is deteriorated, so that there is a problem that signal transmission and reception through the intenna can not be properly performed. Even if the signal transmission / reception is difficult, there is a problem that the sensitivity of the transmission / reception signal is lowered due to the contact failure between the intenna and the clip.

That is, one support piece 142 is formed at each end of the base front body 112 to form the support part 140. Two support pieces 142 are provided on both side ends of the base portion 110. [ Each support piece 142 is disposed under the contact portion 130 and disposed. The support piece 142 is a plate structure having a predetermined area arranged in a direction parallel to the longitudinal direction of the base portion 110. Each of the support pieces 142 has a curved support contact surface 142a at an upper end thereof so that when the contact portion 130 is pressed toward the base portion 110 with respect to the connecting portion 120 The inner surface of the contact piece 132 comes into contact with the support contact piece 132 provided at the upper end of the support piece 142 to apply a supporting force. Further, the support piece 142 is further provided with auxiliary support pieces 144 extending in the crossing direction. The auxiliary support piece 144 is a plate structure having a predetermined area extending in the lateral direction perpendicular to the longitudinal direction of the base portion 110. Since the support pieces 142 are disposed in parallel to the longitudinal direction of the base portion 110, each auxiliary side piece has a plate structure extending in the lateral direction orthogonal to the support pieces 142. In the present invention, the support pieces 142 and the auxiliary support pieces 144 are provided at the respective end positions of the base portion 110, respectively. Support parts 140 in the form of a translator by the support pieces 142 and the auxiliary support pieces 144 are arranged at two positions on the both side ends of the base part 110, respectively. The height of the upper end of the auxiliary support piece 144 is lower than the height of the upper end of the support piece 142 to form a step 144a between the support piece 142 and the support piece 142. [ The inner surface of the contact piece 132 is first contacted with and supported by the upper end of the support piece 142 when the contact piece 130 is pressed and when the contact piece 132 is further pressed The inner surface of the contact piece 132 is held in contact with the upper end of the auxiliary support piece 144 in a secondary manner.

Thus, there is an effect of preventing a transmission / reception trouble or the like caused when the clip does not contact the intenna 4 properly. More specifically, the contact part 130 is formed on the upper end of each support piece 142 protruding upward from both ends of the base part 110 in a state where the contact part 130 is pushed toward the base part 110, The connecting portion 120 which is the connecting portion between the contact portion 130 and the base portion 110 is permanently deformed by the pressing bending force because the inner surface of the contact piece 132, So that the contact portion 130 of the clip does not contact the intenna 4 properly, thereby preventing a trouble such as transmission and reception caused by the contact portion 130 of the clip. When the contact portion 130 is pushed down by the pressing force acting on the side of the intenna 4 of the terminal, the distance between the upper end portion and the lower end portion of the connecting portion 120 to which the base end portion of the contact portion 130 is connected, The main contact piece 132 of the cross section of the contact portion 130 contacts the upper end of each support piece 142 protruding from the upper surface of the base portion 110, The connecting portion 120 connecting the contact portion 130 and the base portion 110 is effectively prevented from being permanently deformed by a force bending force. The contact part 130 is pressed downward (that is, in the direction of the base part 110) with respect to the connecting part 120 when a force pressing the contact part 130 from above is applied, Each support piece 142 of the support part 140 which is raised above the base part 110 supports the contact part 130 from below when the connection part 120 is to be permanently deformed due to the excessive pushing of the contact part 130 It is possible to prevent the connector 120 from being permanently deformed and preventing the contact portion 130 from being returned to the contact portion 130 in a pressed state.

At this time, in the present invention, a portion where the inner surface of the contact piece 132 is contacted with the upper end of the support piece 142 and is supported is a support portion. In the drawing, a portion denoted by SP1 is a supporting point. The upper end of the support piece 142 is provided with a curved support contact surface 142a which is convex upward so that the contact piece 132 is in contact with the circumferential surface of the contact piece 132 The support force acts on the columnar support contact surface 142a of the support piece 142 in a state where the contact surface 142a contacts the columnar support contact surface 142a as wide as possible so that the support force for supporting the contact piece 132 from below can be maximized, It is more effective to prevent the permanent deformation of the contact portion 130 itself and the permanent deformation of the connecting portion 120 which acts to force the contact portion 130 to resiliently restore the base portion 110. [

The auxiliary support pieces 144 constituting the support portions 140 at both end positions of the base portion 110 also function to apply the supporting force when the contact portion 130 is further pushed down, A supporting point is also formed at a portion where the auxiliary support piece 144 and the contact piece 132 are in contact with each other. In the drawing, a portion indicated by SP2 is another support point. This SP2 support point further enhances the permanent deformation preventing function of the connecting portion 120 connecting the contact portion 130 to the base portion 110. [

The tip of the contact piece 132 is inclined upward from the tip of the base 110 in a state where the contact piece 132 which is a main constituent of the contact part 130 is supported by the upper end of the support piece 142 When the contact part 130 is pushed down further in a state where the contact part 130 is first pressed, the contact piece 132 is inserted into the base surface of the base front support piece 114, The support piece 142 protruded over the contact piece 132 is supported so that the contact piece 132 is opened so that the inner diameter of the contact piece 132 becomes larger and as the inner diameter of the contact piece 132 becomes larger, 132 of the contact portion 130 are in contact with the base front support piece 114 at the distal end of the base portion 110 so that the contact portion 130 itself is prevented from being subjected to excessive permanent deformation, A hook connected to the base end side Excessive permanent deformation of teubu 120 is also more reliably prevented. In the drawing, a portion indicated by SP3 is another supporting point, and the supporting point SP3 functions to firmly support the contact portion 130 together with the supporting points S1 and S2. That is, as the contact portion 130 is pressed further toward the base portion 110, the portion supported by the support points SP1, SP2, and SP3 is further extended, so that the force for supporting the contact portion 130 is further increased And the supporting force for preventing the permanent deformation is increased as much as the supporting point for supporting the contact part 130 from the bottom.

The contact bead piece 136 of the contact piece 132 also contributes to the improvement of the conductivity with the intenna 4 by increasing the point of contact with the intenna 4 of the terminal. For example, the contact bead piece 136 of the contact portion 130 itself is more effective in preventing the shape deformation due to the bending force of the contact piece 132, which is the main part, and is more effective in improving the conductivity with the terminal intenna 4 It is an effective configuration.

It is preferable that the width of the contact portion 130 between the left and right sides gradually decreases from the proximal end side toward the distal end side. Specifically, the width of the bridge contact piece 134 constituting the contact portion 130 is set so that the width between both ends of the bridge contact piece 134 becomes smaller from the base end of the base portion 110 toward the tip end portion. In this case, The bending stress transmitted from the contact portion 130 to the connecting portion 120 can be lowered in a state in which the bridge portion 130 is pushed by the contact portion 130. This is effective for preventing permanent deformation of the connecting portion 120, There is also an effect of reducing the material as the width decreases.

In the present invention, both end portions of the connecting portion 120 and the bridge contact piece 134 in the region where the step 144a is formed are connected to the respective side support portions 150 provided at both ends of the base portion 110 Both ends of the remaining region where the step 144a of the contact portion 130 is not spaced apart from the respective side support portions 150 on both sides of the base portion 110 are relatively larger In this case, bending stress transmitted from the contact portion 130 to the connecting portion 120 can be minimized when the contact portion 130 is pushed, thereby helping to prevent permanent deformation of the connecting portion 120 And the effect of material reduction can be expected by reducing the width between the both side ends of the contact portion 130 itself.

In the present invention, it is preferable that the base 110 has a structure in which an upward connecting portion 110uc is further provided on both sides of the bottom surface. The upward connection portion 110uc may be a curved surface or a tapered inclined surface that extends upward at an angle (within an acute angle range) upward with respect to the bottom surface of the base 110. In this case, when the bottom surface of the base portion 110 is soldered (soldered) to the circuit board 2, the soldering area between the solder and the base portion 110 is further increased, so that the mounting strength of the clip is further improved . That is, solder is attached to the upward connecting portion 110uc on both sides of the bottom surface of the base 110, so that the bonding area between the solder and the base 110 is further increased, thereby increasing the bonding strength of the clip.
