Definitions

• the invention relates to an electrical jack-type connector, mainly for low voltage purposes, comprising a rod-shaped male part having terminals in the form of conducting, axially displaced contact rings and a match- ing tubular female part having axially and peripherally displaced inner terminals to form contact with the contact rings of the male part, which female part com ⁇ prises an outer tube and an inner tube fitted therein, which is formed with slots for the arrangement of the terminals of the female part, each in connection with a respective conductor located between the inner tube and the outer tube for connection with cable conductors within a closed end of the outer tube.
• the invention has for its object to provide an improved design of an electrical connector of the kind mentioned, having a very simple construction, comprising a small number of separate parts and having great reli ⁇ ability as regards function and being easy to operate.
• the connector according to the invention is characterized in that the inner tube is formed for tight insertion into the outer tube and has mainly rectangular slots, each being connected on the external side of the inner tube with a comparatively narrow track extending parallel to the tube axis from the slot to an orifice at one end of the inner tube, and that the terminals of the female part comprise short strip-shaped contact flaps, each in connection with its respective conductor and formed for loose arrangement into its respective slot and the associated track prior to the insertion of the inner tube into the outer tube r the conductors being of such length as to, on the inser ⁇ tion of the inner tube into the outer tube, be led through an aperture at one end of the outer tube, which aperture is closed by a cap after connection of the supply lines with said cable conductors.
• the female .part comprises only a few separate components, viz. outer tube, inner tube, contact flaps with conductors and possibly a final cap, of which the two tubes and the cap can be made by moulding from a suitable plastic material, and since the contact flaps with, conductors are loosely mounted in the slots and tracks of the inner tube so as to avoid fastening opera ⁇ tions, the manufacturing costs can be kept very low both in the processing and assembling of the separate compo ⁇ nents. Moreover, the hermetically sealed confinement of the connectors of the contact -flaps resulting from the tight fitting of the inner tube into the outer tube provides a particularly good protection of the electric ⁇ ally conducting components against mechanical and other influences from the environment.
• the contact flaps are mounted in the slots of the inner tube, the flaps will form cords in the inner tube's circular cross section, thus forming good contact at comparatively modest spring pressure.
• the connector ac- cording to the invention is especially suitable for watertight implementation for use in connection with underwater communication equipment and the like, since the connection between the male and female parts can be made watertight without difficulty, and the outer tube in the cable entry end can be closed by a watertight mounted cap.
• FIG. 1 and 2 are perspective views of male and female part, respectively, in a watertight connector ac ⁇ cording to the invention, seen from the outside;
• Fig. 3 is a longitudinal section of the female part ?
• Fig. 4 is a cross section at the line IV-IV in Fig. 3;
• Fig. 5 is a perspective view of the inner tube and contact members of the female part.
• the jack-type male part shown in Fig. 1 has a circular-cylindrical rod-shaped body 1 formed for inser- tion into the tubular .female part, said body having terminals in the form of axially displaced contact rings 2.
• a sealing ring 5 is fitted in a groove 4 for watertight closing in the linking of male and female part.
• the male part 1 finishes with a water ⁇ tight mounted cap 6 which protects the soldering joints between not shown encapsulated conductors for the contact rings 2 and conductors in a cable connected with the male part 1.
• Fig. 2 shows the female part seen from the outside and ending with a watertight mounted cap 8 in the same way as the male part 1.
• the female part 7 comprises an outer tube 9 and an inner tube 10 tightly fitted within the outer tube.
• a number of axially and peripher ⁇ ally displaced, mainly rectangular, slots 11 are formed in the inner tube 10, as is more clearly shown in Fig. 5.
• Each of these slots 11 is connected at one of its lateral edges parallel to the tube axis on the external side of the inner tube 10 with a track 12 extending from the slot 11 in question and opening into the end of the inner tube 10 which is to be placed against the bottom of the outer tube 9.
• the terminals of the fe ⁇ male part are formed as short, planar strip-shaped con ⁇ tact flaps 13 to be arranged in their respective rectan ⁇ gular slots 11 and having such length as to rest on the lateral edges of the slot 11 parallel to the tube axis,
• Each contact flap 13 has at one edge a thread- or strip-shaped conductor 14 which can. be punched together with the contact flap and which on arrangement of the flap 13 in a slot 11 will be placed in the associated track 12 parallel to the tube axis on the external side of the inner tube 10.
• the conductors 14 have each such length as to project beyond the above mentioned end of the inner tube 10 so that when the latter is placed in the outer tube 9, they are led through an opening formed at the end of the outer tube 9.
• the conductors 14 are connected with not shown cable conductors in the same way as the conductors in the male part 1.
