Definitions
- the invention relates to an electrical connector with a connector body having an internal contact pin and at least one external contact spaced radially from the internal contact pin with respect to the longitudinal axis of the connector body, and with a housing element which receives the connector body and which has its inside in the region of its front opening on the contact side rests on the outside of the external contact, such that the external contact of the connector can be pressed radially inwards by an axial movement of the plug body relative to the housing element, to an external contact of a socket.
- Such connectors are known as “RCA connectors” or “RCA connectors” and are used to create a detachable cable connection between consumer electronics devices for the purpose of asymmetrical transmission of an audio signal or a video signal.
- a connector of the type mentioned is described for example in EP 0 460 145 B1.
- a cover sleeve is provided which surrounds the plug body.
- the cover sleeve lies in the area of its front opening on the contact side with its inside on the outside of the external contact attached to the plug body.
- the cover sleeve can be screwed onto the plug body in the axial direction, so that the external contact of the plug is pressed radially inwards against the external contact of a socket matching the plug when the cover sleeve moves in the axial direction relative to the plug body when screwed on becomes.
- a disadvantage of the known connector is that the attachment of the connector to a socket of a corresponding consumer electronics device is relatively cumbersome.
- the sockets built into the device housing are usually attached to the rear of the device.
- the user of the plug must therefore reach behind the device in order to insert the plug into a socket, in order then to tighten the cover sleeve to produce the clamp connection on the plug body with the aid of both hands.
- One hand carries out the rotary movement required for screwing on, while the other hand holds the connector body so that it does not rotate. Attaching the plug is particularly cumbersome when there are a large number of sockets on the back of the device with plugs already inserted therein. This is particularly often the case with hi-fi amplifiers or receivers.
- the object of the present invention is to provide an electrical connector in which the disadvantages and problems outlined above are avoided as far as possible.
- the plug should be plugged into a socket easily and quickly and with the aid of only one hand and be fixable thereon.
- the axial movement of the connector body within the housing element is brought about by the actuation of the lever.
- the plug according to the invention is fixed or detached from the socket by simply actuating the lever.
- the connector can be used easily with the help of only one hand.
- the plug can be gripped with just one hand, for example to insert it into a corresponding socket. After plugging in, only the lever has to be actuated to establish the positive connection between plug and socket, which can also be done with only one hand.
- the lever is actuated again, and then the plug is gripped and pulled out of the socket.
- any screwing movement when fixing the plug to the socket or when loosening the plug is dispensed with, so that the handling of the plug is significantly easier and less cumbersome than with the plugs known from the prior art.
- the external contact of the plug can usefully have a conically shaped end section on its outside, in which case the housing element can have a conical taper in the region of its front opening. In this way, the axial movement of the plug body can be converted into a radial movement of the external contact in a particularly simple manner.
- the housing element expediently consists of a base body and a housing cover which is detachably connected to the base body, the lever being rotatably mounted on the base body.
- the plug body is easily accessible by removing the housing cover from the base body or can even be removed completely from the housing element. This ensures that, for example, the soldering of cables to the internal contact pin or to the external contact of the plug is possible without any problems.
- a particularly advantageous embodiment of the connector according to the invention results from the fact that a ring element is provided which can be detachably attached to the housing element, the base body and the housing cover being held together by the ring body in the region of the front opening of the housing element.
- the ring body gives the housing element a special stability in the area of the front opening, which is expedient since in this area the pressing forces required to fix the plug to the socket must be applied by the housing element.
- the base body and the housing cover can be detached from one another in a particularly simple manner by removing the ring body.
- the lever is designed as a cam lever, the cam portion of which rests on the rear side of the connector body facing away from the contact side.
- the shape of the cam section determines the conversion of the rotary movement of the lever into an axial movement of the plug body.
- the torque acting on the cam lever can reach a high level via the cam section Thrust are converted, which acts on the connector body in the axial direction.
- This has the advantage that a strong contact pressure is applied to fix the plug to the socket, while the actuation of the lever requires only a comparatively small amount of force.
- the cam lever should be shaped in its cam section lying against the plug body in such a way that the cam lever engages in a clamping position in a self-locking manner.
- the housing element should have a cable guide section which is angled laterally with respect to the longitudinal axis of the connector. Due to the lever arranged on the rear of the plug body, a cable connected to the contacts of the plug body cannot be led out of the housing element of the plug in this area. Accordingly, the cable is guided laterally out of the housing element via the laterally angled cable guide section. Because of the laterally angled cable guide section, the housing element advantageously lies particularly well in the hand and can be gripped particularly comfortably for inserting the plug into the socket or for pulling the plug out of the socket.
- the laterally angled cable guide section can be designed in the manner of a “pistol grip”. Appropriately, clamping devices should be provided in the area of the cable guide section, which are used to fix a cable running in the cable guide section to the plug.
- Another useful embodiment of the connector results from the fact that the external contact of the plug is formed in its contact area as an electrically conductive contact tongue, with electrically insulating clamping tongues are provided to fix the plug on the socket, which together with the contact tongue radially inward are pressed against the external contact of the socket. Accordingly, as External contact of the plug uses the electrically conductive contact tongue, so that the external contact - unlike conventional cinch plugs - does not completely surround the internal contact pin. This significantly improves the signal transmission properties of the connector. In order to ensure that the plug is securely attached to the socket, electrically insulating clamping tongues are also provided, which are pressed against the external contact of the socket by axial movement of the plug body relative to the housing element.
- the contact tongue and the clamping tongues interact.
- a particular advantage of the connector designed in the manner described above is that the area of the contact tongue can be selected such that the impedance of the connector produced with the connector can be adapted to the characteristic impedance of the cable used.
- the area of the contact tongue significantly influences the impedance of the connector.
- an optimized impedance behavior can already be ensured during the manufacture of the plug by suitably specifying the area of the contact tongue.
- the contact tongue has a linear elevation on its inside facing the external contact of the socket.
- the line-shaped elevation is used to establish the electrical contact with the external contact of the socket at a precisely defined point.
- the surface of the linear elevation defines the contact area of the plug connection precisely and reproducibly.
- FIG. 1 shows a connector with a plug body that can be inserted into the housing element
- Fig. 2 Illustration of the operation of the plug
- Fig. 3 Exploded view of the connector
- Fig. 4 View of the fully assembled connector.
- the electrical connector according to the invention is generally designated by the reference number 1.
- the connecting plug 1 has a plug body 2, on which an inner contact pin 3 and an outer contact 4, which is radially spaced with respect to the longitudinal axis of the plug body 2, are arranged.
- the external contact 4 of the plug 1 is designed in its contact area, as can be seen from FIGS. 1, 2 and 3, as an electrically conductive contact tongue, with clamping tongues 5 consisting of electrically insulating material being provided for fixing the plug 1 to a corresponding socket.
- a soldering tab 6 is provided for connecting the contact tongue 4 to a cable.
- the plug body 2 is received by a housing element which consists of a base body 7 and a housing cover 8 detachably connected to the base body 7.
- the base body 7 and the housing cover 8 are held together in the region of the front, contact-side opening of the housing element by means of a ring element 9 which can be seen in FIGS. 3 and 4 and which can be detachably attached to the housing element.
- the ring element 9 can be placed on the housing element from the front and engages there.
- the connector body 2 is axially displaceably mounted in the base body 7 of the housing element, wherein a lever 10 is rotatably mounted on the base body 7, which acts on the connector body 2, so that the connector body 2 by actuation of the lever 10 is movable relative to the housing element of the plug 1.
- the lever 10 is designed as a cam lever, the cam section 11 of which rests on the rear side of the plug body 2 facing away from the contact side.
- the plug body 2 is displaced axially towards the front, ie towards the contact side of the plug 1.
- Both the contact tongue 4 and the Clamping tongues 5 have conically shaped end sections on their outer sides, the housing element abutting in the region of its front opening in the region of its inner side on the outer sides of the contact tongue and the clamping tongues, specifically in the contact region indicated by the arrows 13.
- the housing element has a conical taper in this area, so that the contact tongue 4 and the clamping tongues 5 can be pressed radially inwards by the axial movement of the plug body 2 relative to the housing element and an external contact of a socket, not shown.
- the radial movement of the contact tongue 4 and the clamping tongues 5 is illustrated in FIG. 2 using the arrows 14.
- the axis of rotation of the lever 10 is formed by a screw 16 inserted into a sleeve 15, by means of which the housing cover 8 is simultaneously fastened to the base body 7.
- the housing element has a cable guide section 17 which is angled laterally with respect to the longitudinal axis of the connector 1, a clamping screw 18 being provided on the cable guide section 17 for fixing a cable (not shown) running in the cable guide section 17 to the connector ,
