"CONNETTORE COASSIALE TIPO 7/16 PER RADIOFRE-QUENZA, E PARTI COSTITUTIVE DI TALE CONNETTORE" "7/16 TYPE COAXIAL CONNECTOR FOR RADIO FREQUENCY, AND CONSTITUTIVE PARTS OF THIS CONNECTOR"
DESCRIZIONE DESCRIPTION
La presente invenzione concerne un nuovo connettore coassiale tipo 7/16 per radiofrequenza, nonché le parti costitutive maschio e femmina di tale connettore. The present invention relates to a new coaxial connector type 7/16 for radio frequency, as well as the male and female constituent parts of this connector.
Il campo dell'invenzione è quello dei connettori impiegati per realizzare la giunzione di cavi coassiali per radiofrequenza, costituiti da una massa e da un conduttore centrale. The field of the invention is that of the connectors used to make the junction of coaxial cables by radio frequency, consisting of a mass and a central conductor.
Tali connettori presentano una parte maschio ed una parte femmina, reciprocamente accoppiabili per realizzare la giunzione. These connectors have a male part and a female part, which can be mutually coupled to make the junction.
Per questo tipo di dispositivi, le norme DIN 47233 e CECC 22190 impongono che l'impedenza all'interno del connettore sia di 50 ohm. For this type of device, the DIN 47233 and CECC 22190 standards require the impedance inside the connector to be 50 ohms.
Tale valore di impedenza è ottenuto attribuendo, sul lato aria delle parti maschio e femmina del connettore, un diametro di 7 mm al contatto centrale (collegato al conduttore centrale del cavo coassiale), e un diametro di 16 mm allo schermo (collegato alla massa del cavo medesimo). This impedance value is obtained by attributing, on the air side of the male and female parts of the connector, a diameter of 7 mm to the central contact (connected to the central conductor of the coaxial cable), and a diameter of 16 mm to the shield (connected to the ground of the cable itself).
La distanza tra il contatto centrale e lo schermo deve invece essere aumentata in corrispondenza del tratto di connettore occupato dell'isolante di separazione dei due poli, a causa del maggior valore della costante dielettrica del materiale isolante rispetto all'aria. The distance between the central contact and the shield must instead be increased in correspondence with the portion of the connector occupied by the insulation separating the two poles, due to the greater value of the dielectric constant of the insulating material with respect to air.
Allo scopo di non modificare i valori dimensionali del connettore, soprattutto a livello del tratto occupato dal materiale isolante, tra le soluzioni proposte dalla tecnica nota vi è quella di ridurre i diametri del contatto centrale e dello schermo (per esempio di 6 mm e 13,5 mm rispettivamente), in modo da conservare il rapporto dimensionale adatto per dare un'impedenza di 50 ohm. In order not to change the dimensional values of the connector, especially at the level of the section occupied by the insulating material, one of the solutions proposed by the known art is to reduce the diameters of the central contact and of the shield (for example by 6 mm and 13, 5 mm respectively), in order to maintain the dimensional ratio suitable to give an impedance of 50 ohms.
Questa soluzione, tuttavia, non rispetta le suddette normative, che invece impongono la struttura 7/16 per i connettori coassiali per radiofrequenza. This solution, however, does not comply with the aforementioned regulations, which instead require the 7/16 structure for coaxial connectors for radiofrequency.
Lo scopo principale della presente invenzione è quello di realizzare un connettore coassiale del tipo anzidetto che, pur presentando un contatto centrale di 7 mm ed uno schermo di 16 mm, permetta di ottenere il desiderato valore di impedenza anche a livello del materiale isolante, senza dover modificare le dimensioni generali del connettore. The main purpose of the present invention is to provide a coaxial connector of the aforesaid type which, while having a central contact of 7 mm and a shield of 16 mm, allows to obtain the desired impedance value also at the level of the insulating material, without having to change the overall dimensions of the connector.
con le parti femmina e maschio descritte nelle rivendicazioni rispettivamente 1 , 8 e 9. with the female and male parts described in claims 1, 8 and 9 respectively.
Ulteriori caratteristiche del connettore dell'invenzione risultano definite dalle restanti rivendicazioni. Further characteristics of the connector of the invention are defined by the remaining claims.
In particolare, grazie alla struttura in due porzioni separate e reciprocamente accoppiabili del detto materiale isolante, viene consentito di alloggiare il contatto centrale, preventivamente collegato al cavo coassiale, attraverso e all'interno della sua sede nello stesso materiale isolante, pur presentando quest'ultima un diametro più piccolo di quello (7mm) della parte di contatto centrale all'aria. In particular, thanks to the structure in two separate and mutually combinable portions of said insulating material, it is possible to house the central contact, previously connected to the coaxial cable, through and inside its seat in the same insulating material, while having the latter a diameter smaller than that (7mm) of the central contact part in the air.
In questo modo si rende possibile compensare la maggiore costante dielettrica dell'isolante, accrescendo la dimensione di questo rispetto allo spazio in aria del connettore, pur senza dovere aumentare in maniera corrispondente le dimensioni di base del medesimo connettore. In this way it is possible to compensate for the higher dielectric constant of the insulation, increasing its size with respect to the air space of the connector, without having to correspondingly increase the basic dimensions of the same connector.
Questi ed altri scopi, caratteristiche e vantaggi risulteranno evidenziati attraverso un esame della descrizione che segue di un preferito modo di realizzare il connettore secondo la presente invenzione illustrato, a titolo di esempio non limitativo, nelle figure dei disegni allegati. These and other objects, characteristics and advantages will be highlighted through an examination of the following description of a preferred way of making the connector according to the present invention illustrated, by way of non-limiting example, in the figures of the attached drawings.
In esse: In them:
la figura 1 illustra la parte femmina del connettore dell'invenzione assemblata sul cavo coassiale; Figure 1 illustrates the female part of the connector of the invention assembled on the coaxial cable;
gura 1 , pressemblato con una porzione di isolante e collegato al cavo coassiale; Figure 1, press-assembled with a portion of insulation and connected to the coaxial cable;
la figura 3 illustra la fase di assemblaggio del contatto centrale di figura 2 al corpo del connettore di figura 1 ; Figure 3 illustrates the assembly step of the central contact of Figure 2 to the body of the connector of Figure 1;
la figura 4 illustra la parte maschio del connettore dell'invenzione assemblata sul cavo coassiale; Figure 4 illustrates the male part of the connector of the invention assembled on the coaxial cable;
la figura 5 illustra il contatto centrale del connettore di figura 4, preassemblato con una porzione di isolante e collegato al cavo coassiale; Figure 5 illustrates the central contact of the connector of Figure 4, pre-assembled with a portion of insulator and connected to the coaxial cable;
la figura 6 illustra la fase di assemblaggio del contatto centrale di figura 5 al corpo del connettore di figura 4. Figure 6 illustrates the assembly step of the central contact of Figure 5 to the body of the connector of Figure 4.
Il connettore dell'invenzione è formato dalla parte femmina delle figure 1 a 3 e dalla parte maschio delle figure 4 a 6, reciprocamente accoppiate per realizzare la giunzione dei cavi coassiali. The connector of the invention is formed by the female part of figures 1 to 3 and the male part of figures 4 to 6, mutually coupled to make the junction of the coaxial cables.
La parte femmina del connettore è indicata con 1 in figura 1 , ed essa si compone di un corpo 9 di presa e di accoppiamento alla parte maschio. The female part of the connector is indicated with 1 in figure 1, and it consists of a body 9 for gripping and coupling to the male part.
All'interno di questo corpo 9 si trovano alloggiati il contatto centrale 5 del connettore e le porzioni 6 e 1 1 dell'isolante che separa i due poli del cavo coassiale 2. Inside this body 9 are housed the central contact 5 of the connector and the portions 6 and 1 1 of the insulator that separates the two poles of the coaxial cable 2.
Come risulta in particolare dalla figura 2, il contatto centrale 5 del connettore viene preventivamente saldato in 7 al conduttore centrale 3 del cavo coassiale 2; quest'ultimo è Secondo l'invenzione, e come meglio risulta illustrato in figura 3, il contatto centrale 5 presenta una parte in aria 18 avente diametro D1 uguale a 7 mm, e una parte 14 che si impegna sull'isolante, che possiede un diametro D3 minore di D1. As can be seen in particular from Figure 2, the central contact 5 of the connector is previously welded at 7 to the central conductor 3 of the coaxial cable 2; the latter is according to the invention, and as it is better illustrated in figure 3, the central contact 5 has an air part 18 having a diameter D1 equal to 7 mm, and a part 14 which engages on the insulation, which has a diameter D3 smaller than D1.
In corrispondenza di questa parte 14 a diametro ridotto, il contatto centrale 5 reca premontata una prima porzione 6 dell'isolante, di preferenza politetrafluoroetilene (PTFE) o polietilene (PE) (figure 2 e 3). In correspondence with this reduced diameter part 14, the central contact 5 carries a first portion 6 of the insulation, preferably polytetrafluoroethylene (PTFE) or polyethylene (PE) (Figures 2 and 3).
A sua volta, il corpo 9 della parte femmina del connettore reca premontata e fissata al suo interno una seconda porzione di isolante 1 1 , formata con lo stesso materiale della porzione 6 e adatta per individuare un alloggiamento 12 destinato a ricevere ed a trattenere la prima porzione di isolante 6. In turn, the body 9 of the female part of the connector has a second insulating portion 11 pre-assembled and fixed inside it, formed with the same material as the portion 6 and suitable for identifying a housing 12 intended to receive and hold the first portion of insulation 6.
Come è illustrato in figura 3, l'assemblaggio della parte femmina 1 del connettore dell'invenzione viene realizzato inserendo il contatto centrale 5 di figura 2, sul quale sono stati premontati il cavo coassiale 2 e la prima porzione di isolante 6, attraverso l'alloggiamento 12 nella seconda porzione di isolante 1 1 . As shown in figure 3, the assembly of the female part 1 of the connector of the invention is carried out by inserting the central contact 5 of figure 2, on which the coaxial cable 2 and the first insulating portion 6 have been pre-assembled, through the housing 12 in the second portion of insulation 1 1.
L'inserimento viene proseguito fino a portare la parte 18 del contatto centrale 5 a sporgere nella parte in aria del connettore e quella 14, dotata della prima porzione di isolante 6, a bloccarsi all'interno del medesimo alloggiamento 12 nella seconda porzione di isolante 1 1. The insertion is continued until the part 18 of the central contact 5 protrudes in the air part of the connector and that 14, equipped with the first portion of insulator 6, locks inside the same housing 12 in the second portion of insulator 1 1.
' lante 6 e 1 1 è del tipo a baionetta, dove la forma dell'alloggiamento 12 possiede una sezione rastremata o a gradino 17, corrispondente a quella 16 della porzione di isolante 6, in modo da consentire l'inserimento di quest'ultima nel medesimo alloggiamento 12. The lante 6 and 11 is of the bayonet type, where the shape of the housing 12 has a tapered or stepped section 17, corresponding to that 16 of the insulating portion 6, so as to allow the latter to be inserted into the same housing 12.
Il bloccaggio in posizione del cavo 2 viene assicurato per impegno di questo con la filettatura 8 del corpo 9 del connettore e mediante una successiva saldatura 10. The locking in position of the cable 2 is ensured by engagement of this with the thread 8 of the body 9 of the connector and by a subsequent welding 10.
Nel rispetto della specifica normativa, in corrispondenza della parte in aria del connettore il diametro D1 della parte 18 del contatto centrale 5 è di 7 mm, mentre il diametro D2 dello schermo 15 è pari a 16 mm. In compliance with the specific legislation, in correspondence with the open part of the connector, the diameter D1 of the part 18 of the central contact 5 is 7 mm, while the diameter D2 of the shield 15 is equal to 16 mm.
In questo modo viene garantito il valore di 50 ohm dell'impedenza nella parte aN'aria del connettore. In this way the impedance value of 50 ohms in the air part of the connector is guaranteed.
Con lo scopo di avere lo stesso valore di impedenza anche sul lato dell'isolante, funzione della costante dielettrica di questo, senza tuttavia dover aumentare le dimensioni del connettore rispetto a quelle stabilite per la sua intercambiabilità, il diametro della parte 14 del contatto centrale 5, lato isolante, è stato portato ad un valore D3, minore di quello D1 anzidetto. Infine la struttura del materiale isolante in due porzioni 6 e 1 1 , delle quali la prima premontata sul corpo del connettore centrale, ha permesso di applicare il contatto centrale 5, già collegato al cavo 2, all'interno del corpo 9 del connettore, attraverso un allogaria 18 del medesimo contatto 5. With the aim of having the same impedance value also on the side of the insulator, a function of the dielectric constant of this, without however having to increase the dimensions of the connector with respect to those established for its interchangeability, the diameter of the part 14 of the central contact 5 , on the insulating side, has been brought to a value D3, lower than the aforementioned D1. Finally, the structure of the insulating material in two portions 6 and 11, of which the first pre-assembled on the body of the central connector, made it possible to apply the central contact 5, already connected to the cable 2, inside the body 9 of the connector, through an algaria 18 of the same contact 5.
La precedente descrizione della parte femmina 1 del connettore dell'invenzione può essere ugualmente ripetuta per la parte maschio 13 delle figure 4 a 6. The previous description of the female part 1 of the connector of the invention can be equally repeated for the male part 13 of figures 4 to 6.
All'invenzione, sopra descritta ed illustrata, è possibile apportare delle modifiche per realizzare varianti che, tuttavia, rientrano nell'ambito delle rivendicazioni che seguono. To the invention described and illustrated above, it is possible to make modifications to realize variants which, however, fall within the scope of the following claims.
