Definitions
- the invention relates to a circular connector for industrial applications according to the preamble of claim 1.
- Connectors without vibration protection are used in various industrial areas. They usually consist of an elastic handle body and a contact carrier with connection cable.
- the connection cable is positioned longitudinally or at 90 ° to the direction of insertion.
- the handle body encloses sections of both the contact carrier and the connection cable.
- the handle body is designed as a housing with internal contact terminals.
- the industrial automation technology may be provided, a union nut is provided with internal thread.
- a union nut is provided with internal thread.
- the sensors are firmly connected via the respective connection cable with a control / evaluation unit. Frequently not only the sensor signals are evaluated in the control / evaluation units, but also the voltage supply of the sensors is provided from there.
- connectors are used in very harsh industrial environments.
- One area of application for these connectors is the food sector, where strict hygiene regulations apply to the systems. To clean them usually acidic or basic cleaning / disinfecting agents are used.
- Lead connector for corrosion of conductive components within the connector (eg on the contact carrier).
- O-rings are often used to seal such smaller connectors compared to M12 connectors. Since, however, no defined bearing or stop surface are provided for these, the O-ring can be moved or squeezed when closing the screw from its intended position, because between the connector and counterpart a certain axial play must be provided. In both cases, the sealing effect can be impaired
- Crimping of the O-ring takes place to a greater extent when standard deviations occur in the manufacture of the connectors or their counterparts, as they can not be ruled out by global manufacturers.
- the object of the invention is therefore to provide a circular connector, which does not have the disadvantages mentioned above, which in particular allows a durable and long-term stable sealing of a connector.
- the essential idea of the invention is to provide a specially shaped sealing element in a generic circular connector, the sealing surface is divided into two areas, wherein a first sealing portion predominantly for a radial Sealing effect and a second sealing portion is designed for a predominantly axial sealing effect.
- FIG. 1 perspective view of a circular connector partially cut
- FIG. 2 enlarged view of a contact carrier with a sealing element according to the invention shown in FIG. 1 in a vertical plan view
- Fig. 3a shows a sectional view of a contact carrier with the sealing element according to the invention in the installed state with a standard counterpart
- FIG. 3 b sectional view of a sealing element in the installed state with a deviating from the standard counterpart
- FIG. 4 sectional view of a contact carrier with a conventional sealing element in the installed state with a counterpart
- the female part of an M8 round connector (femal) is shown.
- the circular connector 1 has a union nut 3 with a metric internal thread M8 made of metal (preferably stainless steel, brass or zinc die-cast) and key surfaces 4a for a hexagon key and a knurling 4b for a manual operation.
- the union nut 3 is rotatably held by a corresponding metallic stop sleeve 5, which encloses a cylindrical contact carrier 7.
- a plurality of contact elements 9a, 9b, 9c are provided, which serve as sockets are executed and connected to individual cable 11 b, c of a connecting cable 11.
- the contact carrier 7 and the connecting cable 11 are at least partially surrounded by an elastic grip body 13.
- the grip body 13 connects at the front end of the circular connector in the region of the stop sleeve 5 to the union nut 3 and surrounds the cable jacket 15 of the connection cable 11 at the rear end of the circular connector 1 in a form-fitting manner.
- the handle body 13 is designed as an injection molded part.
- a bonding agent in the overlap region of the connection cable 11 with the handle body 13 and the extrusion of the contact carrier 7 a permanent flexible connection between the handle body 13 and the connecting cable 11 is achieved, which is very advantageous in terms of the sealing effect against moisture.
- the bonding agent is applied during manufacture in the overlapping area on the cable sheath 15, the single cable 11 and the contact carrier 7.
- the circular connector 1 is connected to a connector counterpart, not shown, having suitably formed contact elements.
- Such a counterpart can, for. B. on a sensor, for. B. an inductive proximity switch
- M8 ifm IE5349 or JAC200 approved for the wet area may be provided.
- the senor is then with a control / evaluation unit on the
- Sealing element 17 made of FPM / FKM (Viton) provided.
- Fig. 2 is an enlarged view (CAD drawing) of the contact carrier 7 with a sealing element 17 according to the invention shown in FIG. 1 in a vertical plan view once in the mounted state and once as a separate part.
- the handle body 13 as encapsulation and the union nut 3 are not shown for the sake of clarity.
- the sealing element 17 has a plurality of lugs 17 a, which protrude into corresponding provided on a collar 40 of the contact carrier 7 openings 40 a and engage with a better visible in Fig. 3 bead 8.
- the sealing element 17 is captively fixed by sliding (in the arrow direction) of the stop sleeve 5. Overall, the sealing element 17 is thus held firmly on the contact carrier 7.
- the collar 40 or the slightly projecting nose tips of the lugs 17a serve as a stop for the stop sleeve 5. Wherein the supernatant due to the elasticity of the entire sealing element 17 and thus the lugs 17a resiliently acts on the stop sleeve 5.
- the stop sleeve 5 is formed as a securing element for a known from DE102005056563 anti-vibration and therefore has on one side edge a plurality of inclined surfaces 5a, which act with appropriate provided on the nut 3 counter surfaces, so act that the nut 3 screwed relatively easily but solved only correspondingly difficult can be.
- sealing element 17 is shown as a sectional view in which the sealing surface F is better visible. It can be seen clearly that the sealing surface is divided into two differently curved sections F1 (cone-shaped) and F2 (convex). It can also be said that section F1 is more conical and section F2 is more spherical.
- the sealing surface points in the direction of the front edge 72 of the contact carrier 7.
- Fig. 3a shows a sectional view of a contact carrier 7 with the sealing element 17 according to the invention in the installed state with an indicated standard counterpart (male / male).
- the contact carrier 7 of the socket part is already inserted into the sleeve-shaped receiving area of the plug part.
- the stop sleeve 5 is located at the nose ends of the lugs 17a and just does not touch the broken collar 40, which is not visible in this sectional view.
- Fig. 3 b shows a sectional view of a contact carrier 7 with the sealing element 17 according to the invention in the installed state with a deviating from the standard connector counterpart (male).
- the diameter is larger than with standard connectors.
- FIG. 4 shows a plug connection with a conventional socket part with an O-ring 100 as a sealing element.
- O-ring 100 As a sealing element.
- it can easily come to a misalignment between the two parts book / plug of the connector, which inevitably has a squeezing of the O-ring 100 result. Damage to the O-ring can not be ruled out. Such damage is usually not visible to the naked eye, so that a user does not recognize this error in a visual inspection. The effects of such damage often only become noticeable after a long delay.
- the O-ring 100 Since the O-ring 100 is pushed only on the contact carrier, it can easily be lost, z. B. when glued to the plug part.
- the sealing element 17 is safe by the latching on
- the solution according to the invention can be used with all existing M8 connectors / devices.
