Abstract

The support (1) has rectangular support branches (1A-1C) equally distributed around a central column (1D). Width of the branches is made such that outer edges of the branches are arranged in a geometric cylinder of section equal to an internal section of a helical antenna (2). Comb elements (2A-2C) comprise slits spaced at a pitch identical to that of turns of the antenna. The elements are fixed on the outer edges of the branches, with the slits facing the branches. The elements have U section whose branch comprises the slots. The elements are connected to each of the branches by a hinge.

Description

Soporte de antena helicoidal. Helical antenna support.

La invención se refiere a un soporte de antena helicoidal. The invention relates to a helical antenna support.

Más precisamente, se refiere a una antena interna de un producto que se comunica por radio, en especial para productos contadores, tales como módulos de telelectura de contadores de fluido o de electricidad. More precisely, it refers to an internal antenna of a product that communicates by radio, especially for meter products, such as telemeter modules for fluid or electricity meters.

La antena va soldada a la tarjeta electrónica del producto y debe estar orientada correctamente para sintonizarse a la radiofrecuencia de funcionamiento. The antenna is soldered to the electronic board of the product and must be correctly oriented to tune to the operating radio frequency.

Ahora bien, ésta puede deformarse en su montaje sobre la tarjeta electrónica y el paso de las espiras, que es un parámetro importante de funcionamiento, puede variar asimismo con el tiempo y degradar las prestaciones del producto. However, it can deform in its assembly on the electronic card and the passage of the turns, which is an important parameter of operation, can also vary over time and degrade the performance of the product.

Por lo tanto, ya se ha contemplado consolidarla por medio de un soporte. Therefore, it has already been contemplated to consolidate it by means of a support.

Un soporte de antena helicoidal se describe en la patente 5406693. A helical antenna holder is described in patent 5406693.

Este soporte se constituye a partir de cuatro elementos conformados en forma de cruz y solidarios con una base cilíndrica, siendo estos elementos placas rectangulares y estando provistos de ranuras dispuestas con un paso preciso sobre su borde externo. Entre estos elementos van dispuestos unos elementos en forma de cuña y, así, se dispone un hilo conductor en las ranuras y contra las cuñas para formar una antena. Las cuñas se quitan a continuación por deslizamiento y la antena queda así formada y soportada por el soporte. This support is constituted from four elements formed in the form of a cross and integral with a cylindrical base, these elements being rectangular plates and being provided with grooves arranged with a precise passage on its outer edge. Between these elements are arranged wedge-shaped elements and, thus, a conductive wire is arranged in the grooves and against the wedges to form an antenna. The wedges are then removed by sliding and the antenna is thus formed and supported by the support.

Este modo de soporte implica una fabricación de la antena directamente sobre el soporte. Si se adquiere una antena ya fabricada en forma de hélice, el soporte descrito en esa patente no conviene. This support mode involves manufacturing the antenna directly on the support. If an antenna already manufactured in the form of a propeller is acquired, the support described in that patent does not suit.

En efecto, su colocación en las ranuras del soporte implica bien una deformación por distanciamiento de la antena para encajar las espiras en las respectivas ranuras, o bien un atornillado por rotación de la antena sobre las ranuras. In fact, its placement in the grooves of the support implies either a deformation by distancing the antenna to fit the turns in the respective slots, or a screwed by rotation of the antenna on the slots.

Ahora bien, estos dos modos de montaje consumen mucho tiempo y son complejos y, sobre todo, son susceptibles de degradar la antena, que se constituye a partir de un hilo relativamente fino. However, these two mounting modes are time consuming and complex and, above all, are susceptible to degrading the antenna, which is constituted from a relatively fine wire.

La invención soluciona este problema proponiendo un soporte de antena helicoidal que, destinado al montaje de una antena ya fabricada, asegura una perfecta sujeción de las espiras de la antena con un paso preciso. The invention solves this problem by proposing a helical antenna support which, intended for the assembly of an already manufactured antenna, ensures a perfect clamping of the turns of the antenna with a precise step.

Para tal fin, la invención propone un soporte de antena helicoidal que incluye al menos tres ramas de soporte sensiblemente rectangulares equidistribuidas alrededor de una columna central, siendo la anchura de estas ramas de soporte tal que su borde externo queda dispuesto sobre un cilindro geométrico de sección sensiblemente igual a la sección interna de la antena, caracterizado por incluir asimismo al menos tres elementos de peine que, incluyendo ranuras espaciadas a un paso idéntico al de las espiras de la antena, están destinados a ser fijados a cada borde externo de dichas ramas de soporte, con sus ranuras dirigidas hacia dichas ramas de soporte. For this purpose, the invention proposes a helical antenna support that includes at least three substantially rectangular support branches distributed around a central column, the width of these support branches being such that their outer edge is arranged on a geometric sectional cylinder substantially equal to the internal section of the antenna, characterized by also including at least three comb elements that, including grooves spaced at a step identical to that of the turns of the antenna, are intended to be fixed to each outer edge of said branches of support, with its grooves directed towards said support branches.

Gracias a la invención, se evita toda deformación y, por tanto, toda pérdida de funcionamiento de la antena. El montaje de la antena sobre una tarjeta electrónica así como su orientación se ven asimismo facilitados. Thanks to the invention, any deformation and, therefore, any loss of antenna performance is avoided. The mounting of the antenna on an electronic card and its orientation are also facilitated.

De acuerdo con una forma preferida de realización de la invención, dichos elementos de peine se conforman a partir de un perfil en U, del cual cada rama de la U incluye dichas ranuras, y destinados a ser encajados sobre el borde externo de cada rama del soporte. According to a preferred embodiment of the invention, said comb elements are formed from a U-profile, of which each branch of the U includes said grooves, and intended to be fitted on the outer edge of each branch of the support.

Ventajosamente, dichos elementos de peine incluyen al menos una espiga de engatillado en un orificio practicado en el borde externo de dichas ramas de soporte. Advantageously, said comb elements include at least one crimping pin in a hole made in the outer edge of said support branches.

Dichos elementos de peine pueden estar vinculados a cada dicha rama de soporte mediante una bisagra. Said comb elements may be linked to each said support branch by means of a hinge.

Dichas ramas incluyen ventajosamente una anchura suplementaria de apoyo de la espira inferior de la antena. Said branches advantageously include a supplementary support width of the lower loop of the antenna.

El soporte puede incluir un orificio de guía del extremo de dicha antena destinado a fijarse a una tarjeta electrónica. The support may include a guide hole at the end of said antenna intended to be fixed to an electronic card.

La invención queda descrita a continuación con mayor detalle con la ayuda de figuras que tan sólo representan formas preferidas de realización de la invención. The invention is described in greater detail below with the help of figures that only represent preferred embodiments of the invention.
