Definitions

  • the invention is based on a connection according to the preamble of claim 1.
  • Extension cables are known (Bosch car antenna catalog 1986, page 26), but they assume that the cable ends of the extension cable have different plug elements, namely an antenna plug and a socket.
  • the known plugs are usually mechanically connected to the cable ends by extrusion coating.
  • the invention is therefore based on the object of developing the known connection in such a way that a connection which is simple to manufacture and operates reliably is produced.
  • connection has a simple structure and functions reliably under high mechanical stresses such as occur in a motor vehicle.
  • the contact spring has an approximately triangular cross section. This ensures good contact between the elongated contact spring and the connector pins of the mother connector of the two coaxial cables to be connected.
  • Fig. 1 denotes an antenna cable, one end of which is not shown is detachably or permanently connected to a car antenna and the other end 11 has a coaxial mother plug 12 which is designed as an angle plug and which can normally be plugged onto a corresponding father plug of a car radio input.
  • a coaxial adapter piece 13 is inserted into the mother connector 12, which dips a little less than half its length into the mother connector 12.
  • a mother plug 14 of an extension cable 15 is then plugged onto the end of the adapter piece 13 protruding from the mother plug 12.
  • the other end of the extension cable 15 can either, as shown in FIG. 3, also be provided with a mother plug 16 or, as in the case of an extension cable 17 according to FIG. 4, with a straight coaxial antenna plug 18.
  • the coaxial mother connector 16 fits into a corresponding connector element of a car radio.
  • the mother plug 12 has a resilient outer conductor contact 21 in the form of an axially multiply slotted cap and an insulated central plug pin 22.
  • the insulation between the outer conductor contact 21 and the plug pin 22 is achieved simultaneously with the manufacture of the cap-shaped insulating material part by spraying or pressing.
  • a radially projecting insulating material tube 23 is also formed, which encloses the insulation of the antenna cable and connects to it; see. also Fig. 4.
  • the plug pin 22 is provided at its free end with a conical taper 24, and the free end of the outer conductor contact 21 has an inwardly directed projection 25, the meaning of which is explained below.
  • the adapter piece 13 (FIGS. 2, 5 and 6) has an electrically conductive sleeve 30, in which a cylindrical insulating material bushing 31 is fastened. An opening 32 of the insulating material bushing 31 is somewhat enlarged in diameter over most of its length, so that a receiving opening 34 is created for an elongated contact spring 35.
  • the elongated contact spring as shown in Fig. 6, has an approximately triangular cross section and is provided with a longitudinal slot 36 so that it can be compressed somewhat to be inserted into the receiving opening 34.
  • the elongated contact spring 35 decreases when plugged together Mother connector 12 and adapter piece 13 on the connector pin 22 of the mother connector. The contact is then made in a line at the points identified by a, b, c; see.
  • the electrically conductive sleeve 30 is provided on its circumference with a constriction 37 (Fig. 5), so that the projection 25 of the outer conductor contact 21 bears against the undercut 38 formed by the constriction 37. This prevents the adapter piece 13 from accidentally falling out of the mother plug 12.
  • the conical taper 24 on the plug pin 22 facilitates the insertion of the same into the elongated contact spring 35.

Claims (8)

  1. Raccord pour deux câbles coaxiaux dont les extrémités sont munies des mêmes prises femelles (12, 14) coaxiales, qui présentent un contact conducteur externe (21) en forme de douille et un contact de conducteur interne (22) en forme de tige isolé du premier et une pièce d'adaptation (13) coaxiale reliant les deux prises femelles, qui présente un élément de contact conducteur interne (35) s'adaptant au contact conducteur (22) interne en forme de tige et un élément de contact conducteur externe (30) en forme de douille s'adaptant au contact conducteur externe en forme de douille, caractérisé en ce que, dans l'élément de contact conducteur externe (30) de la pièce d'adaptation (13), on fixe une gaine (31) de matière isolante, dans l'orifice (34) de laquelle passe un ressort (35) de contact fendu longitudinalement pour recevoir les contacts (22) de conducteurs internes des prises femelles (12, 14) par interpénétration par la forme et que les contacts conducteurs externes (21) en forme de douille des deux prises femelles (12, 14) entourent de manière élastique aux zones terminales, l'élément de contact conducteur (30) externe de la pièce d'adaptation.

  4. Raccord selon la revendication 1 ou 2, caractérisé en ce que le ressort de contact (35) présente une section triangulaire.
  5. Raccord selon la revendication 1 ou 3, caractérisé en ce que la douille (30) électriquement conductrice de la pièce d'adaptation (13) est en laiton ou un alliage du laiton.
  6. Raccord selon la revendication 1, 2 ou 4, caractérisé en ce que le ressort de contact (35) est en bronze.
  7. Raccord selon la revendication 1, 2 ou 4, caractérisé en ce que le ressort de contact (35) est en argentan.
  8. Raccord selon l'une des revendications 1 à 7, caractérisé en ce que la prise femelle coaxiale (12, 14) est sous forme de fiche coudée.
