Definitions
- the invention relates to an antenna, in particular for mobile radio devices, and to a method for its production and method for installation until final assembly.
- Known mobile radio antennas are, for example, integrated antennas which are adapted to the inside wall of a mobile radio device and thus do not appear visually to the outside.
- These integrated antennas which are relatively expensive to produce, have the disadvantage that their transmission / reception efficiency is usually poorer than that of the helix antenna, in particular when the volume of the integrated antenna is limited. With the same battery capacity, this results in a reduction in the operating time between two charging processes or, in the case of the same operating time, correspondingly requires more battery capacity. A connection to the base station can also break off prematurely.
- Cellular antennas in the form of so-called helix antennas are also known. These antennas are essentially made of wire and consist of a helical transmission and reception part, the helix part, and a contacting part, which is coupled to a flat module of the mobile radio device for transmitting the transmission / reception energy. These antennas are usually housed in a housing (antenna stub) which protrudes from the housing of the mobile radio telephone.
- Rotational position must be brought to the assembly.
- the contacting of the antenna according to the invention with a printed circuit board or flat module can be carried out as a pressure contact according to FIG. 2.
- An antenna described does not require any additional auxiliary parts, such as an antenna spring, so that handling and costs are optimized.
- the advantage of pressure contacting with the coiled contacting part of the antenna according to the invention is that the orientation in the rotational position is not necessary during assembly. Furthermore, any desired spring stiffness can be easily produced on the antenna by appropriate design of the wire diameter, the turn diameter and the number of turns arranged close to one another. Despite the shape and position tolerance of the partners to be contacted, the required pressure contacting can be achieved easily and permanently.
- An essential feature of the contacting part of the antenna produced by winding technology is that the turns have direct electrical contact with one another even in the contacted state, as shown in FIGS. 1 to 4. This is achieved in that the turns are produced in such a way that they abut one another with a prestress. This should be ensured, as otherwise the transmission and reception quality of the antenna may decrease.
- antenna form according to the invention is that the antenna can be conveyed directly into plastic tubes by an automatic winder, which on the one hand prevents damage, for example during transport as bulk goods, and on the other hand correctly offers the antenna position to an automatic assembly machine. This makes it possible, for example, to save the usual vibratory spiral conveyors in automatic assembly machines. Exemplary embodiments are described below with the aid of schematic figures:
- FIG. 1 and 2 show antennas of the same internal structure with the example of a pressure contact in FIG. 2,
- FIGS. 3 and 4 have a variant of the configuration of the contact part, different spring effects being realized,
- FIGS. 5 and 6 are also largely identical in construction, with pressure contact being made axially by pressing on a contact patch and the initially spaced turns in the contacting part being compressed,
- Figure 7 shows an exploded view of an antenna with an associated capped housing, the second snap hooks (2) for locking in one
- FIGS 8A and 8B illustrate the prior art.
- FIGS. 8A and 8B comprises a technique with a transmitting / receiving part (15) and a contacting part (6).
- the contacting part (6) differs significantly from a rotationally symmetrical part, which would take any position on a flat surface. Rather, the position of a component according to the state of the
- Technology is determined by the asymmetrical shape of the contacting part (6) and provides the described difficulties in feeding to an assembly process and in receiving by a handling device.
- helix antennas In the case of mobile radio devices, there are so-called helix antennas, ie the antenna (material preferably wire) is consists of a helically coiled "transmit and receive part" (helix part) and a contacting part, with which the transmit / receive energy is conducted from or to the printed circuit board. These antennas are usually housed in a housing (antenna stub) that protrudes from the housing of the mobile phone.
- the production is also cost-intensive (but not as much as with integrated antennas), since the contacting part can only be shaped by bending the wire several times in space.
- the invention had for its object to provide a helical antenna e.g. to provide for cellular phones
- the solution according to the invention of these attachments is a helical antenna which is produced exclusively or predominantly by a winding / winding process.
- FIG. 1 Manufacturing costs approx. 1/4 to 1/6 of the previous helical antenna
- FIG. 1 Such winding processes are known from the manufacture of tension springs, in which instead of eyelets on the spring ends according to FIG. 1 (contacting part lower end), shaped ends are produced by winding / winding become.
- a spring produced in this way also has the advantages 1 to 3 mentioned above.
- Another advantage of an antenna manufactured in this way is that, due to the wound-on end ring at the upper end of the helix, advantageous transmission and reception properties are achieved and the antenna no longer has to be brought into an optimal rotational position.
- the contacting of the antenna according to the invention with the printed circuit board / printed circuit board assembly is a pressure contacting according to FIG. 2.
- the advantage of pressure contacting with the coiled contacting part of the antenna according to the invention is that here, too, no rotational orientation is required during assembly, and that each wire diameter, coil diameter and number of coils tightly wound on one another easily Desired "spring stiffness" can be produced and thus the required contact pressure is easily and permanently achieved despite the shape and position tolerance of the partners to be contacted.
- An essential feature of the contacting part of the antenna produced by winding technology is that the windings, even in the contacted state, have direct electrical contact with one another (applies exactly only to FIGS. 1 to 4). This is achieved by producing the windings in such a way that they lie against one another with a prestress.
- the transmission and reception quality of the antenna may decrease.
- the antenna shape according to the invention is that the antenna can be conveyed by the automatic winder directly into plastic tubes, which on the one hand damage e.g. prevent it from being transported as bulk goods and secondly offer the antennas in the correct position to an automatic assembly machine.
- This can e.g. the usual vibratory spiral conveyor can be saved with automatic assembly machines.
- the helical antenna is inserted into the opening of the housing with the contact part first in the housing provided in the correct position, FIG. 7 (longitudinal axis vertical, large housing opening upwards).
- the contacting part is centered in the conical part of the housing and initially sits on the snap hook 1.
- the snap hooks 1 are pressed over until the end position of the helical antenna in the housing is reached.
- the offset pin ensures that the pressing force does not act on the elastic helix part, but only on the pressure-resistant part of the contact part.
- the snap hooks 1 are opened so far before the antenna is joined that the antenna reaches its end position, for example due to gravity. Then the snap hooks 1 are released and thus fix the antenna in the housing.
- the pre-assembly of the antenna is completed by closing the housing with the lid.
- the centering pin in the middle of the lid limits the range of movement of the helix without touching it itself. The result of this is that the vibrations of the helix are limited and rapidly subside in the event of an impact.
- the lid itself is preferably connected to the housing by a snap connection.
- the pre-assembled antenna (antenna in the housing, cover on the housing) is inserted into the mobile phone housing and snaps in with the snap hooks 2. Then the circuit board is inserted into the mobile phone housing perpendicular to the longitudinal axis of the antenna and e.g. locked with snap hooks.
- the contacting spot hits the lower end of the contacting part, the necessary contacting pressure being generated by bending the contacting part to the side (FIG. 2).
- the spring rate of the contacting part can be advantageously designed.
- FIG. 5 and FIG. 6 Another principle of pressure contacting is shown in FIG. 5 and FIG. 6.
- Figure 5 shows the pre-assembled antenna and the contact patch of the circuit board.
- the necessary contacting pressure is generated by the last lower turns of the contacting part, which are designed as compression springs. In the non-contacted state, these have the winding spacing 1.
- Figure 7 shows the individual components of the antenna.
