In conventional technology, displays are used in many electronic appliances, for example, in mobile phones, and in so-called "Organizer" or PDA (Personal Digital Assistant) and measuring devices. Here, the display must be fixed in various electronic appliances, and this can be achieved in various ways. One possible fixing method is to solder the display directly to a circuit board (Pltine) of the appliance with a soldering rod (LStstift) under an opening of the casing, so the display can be seen from the outside through the casing opening. Here, the soldering rod also needs to mechanically fix the display and make conductive contact. However, this fixing method is rigid (inelastic), so the force applied to the housing of the appliance can cause damage to the display. According to another possible fixed method. The display is first put into a metal frame, and the metal frame is screwed with the casing of the device in an opening of the casing. Here, the conductive contact of the display is achieved in a conventional manner with a flat ribbon wire. But here, the display is also more susceptible to damage by external forces. Finally, there is another possibility to pre-install the display on the circuit board of the appliance, where the circuit board is fixed below the opening of the housing by using a spacer pin. On the housing of the appliance. Therefore, the display can be seen from the outside through the housing opening 200302992. But this kind of fixing method is also rigid, so it ’s sensitive to external forces. [Advantages of the present invention] Therefore, the present invention provides a holding member having a holding unit for fixing a display, especially for fixing a display in a housing of an electronic appliance, wherein the display can be supported on the holding in a floating manner. There is at least one degree of freedom in the unit. This means that the display can be flexed when subjected to external force to avoid damage to the display. The display is supported in the holder of the invention in a floating manner and can be advantageously used in a hand tool (which is used in component position operation) or in an orientation device (Ortungsgerat), because the holder of the invention It protects the display from force and prevents damage. Particularly advantageous are appliances that have large sensitive displays, such as azimuth positioning instruments, laser rangefinders, etc. Preferably, the display is supported not only to float in one degree of freedom of movement, but also to float in several degrees of freedom of movement to minimize the risk of damage due to external forces. Therefore, the holder according to the present invention can be flexed to prevent a pressure load from acting on the display, and to prevent the holding-down effect of the holder. The effect that the display is supported in the holder in a floating manner should preferably be caused by a cushioning element, which cushions and / or relaxes the external force acting on the display, so as to prevent the display from being damaged. It is better that the cushioning element has both damping and elastic material properties, because the suspension system with pure spring elasticity 200302992 will cause the display to vibrate during holding if there is no mechanical damping effect. In this preferred embodiment of the present invention, the buffer element is composed of an antistatic material to prevent the electronic structure from being damaged due to the electrostatic charging effect of the display or the buffer element. In a modification of the present invention, at least a part of the buffer element is made of an electrically insulating material, for example, preventing short circuit or leakage current (Kriechstr5me) through the buffer element. On the contrary, according to another modification of the present invention, the buffer element is at least partially composed of a conductive material. For example, in the case of a mobile phone, this is advantageous if the cushioning element forms part of the electrical shield of the appliance housing. In general, non-conductive materials such as rubber, for example, can be embedded with carbon fiber Or steel wool (Stahlwolle) to make it conductive. Furthermore, within the scope of the invention, the cushioning element can be made from a heat-shrinkable material. Thus, for example, the display can be placed in the cushioning element during installation, and then the cushioning element is contracted and bonded to the display using a hot air oven. This has the advantage that the cushioning element makes a reliable mechanical engagement with the display after shrinking, which prevents the display from moving relative to the cushioning element in the future. Preferably, the buffer element is mechanically prestressed in the installed state. 俾 The display is fixed in the holder using the prestress, but the prestress of the buffer element should be small. 俾 When the display is under external force, the It damages the soil but can flex. In this preferred embodiment, the holder of the present invention has a receiving portion into which the display is placed. This accommodating part is equivalent to the metal frame described in the above description of the background art 200302992, but in the case of the holder of the present invention, the display is not connected to the accommodating part in a rigid manner, so as to prevent the external force or the accommodating part from surrendering The monitor is damaged. The accommodating portion is preferably frame-shaped, wherein an outer edge of the display rests on an inner side of the frame-shaped accommodating portion. The display is preferably fixed in the accommodating portion by a cover, which is placed in the accommodating portion in a manner similar to the display and holds the display in the accommodating portion. Here, a buffer element should be provided between the cover plate and the display so that the display can flex from the outside to the outside when an external force is applied. In addition, the buffer element may also be partially disposed between the display and the accommodating portion on the side of the display facing away from the cover plate, so that the display can also be flexed outward, which can further reduce damage. Office. In a modification of the present invention, the protection of damage can be made better in the following manner, which is to make the side edge of the display completely covered by the buffer element, so that the display is supported to float in all freedom of movement 〇The structure of the omnidirectional floating support of this display can be achieved in the following ways in structure: a substantially plate-shaped punching element is provided, which has a protruding edge, wherein one of the edges is provided on the inner side. A circumferential slot to accommodate the side edges of the display. Therefore, in this embodiment, when the side edge of the display is in the installed state, it is located in the surrounding groove of the buffer element, so the display can move in all directions. Here, it is preferable that the side edge of the display and the surrounding groove form a press-fitting portion to prevent the display from being moved improperly during installation. The thickness of the buffer element 200302992 should be approximately equal to the thickness of the display. This is a compromise between saving space (smaller thickness) and buffering capacity (larger thickness). The display or cover is fixed to the holder of the present invention. The function of the accommodating part should preferably be an engaging joint member, which has an elastic engaging joint. The advantage of this fixing method is that the display can be quickly installed or removed without tools. Other advantages can be found in the illustrations below. An embodiment of the present invention is shown in the drawings. Many combinations of features are included in the drawings, descriptions, and patent applications. Experts can also regard these characteristics as individual characteristics and make further advantageous combinations.
