Definitions

  • the invention relates to a plug socket for plug pins with a cylindrical, sleeve-shaped base body, a partial surface of the base body wall being bent into the base body cavity about a bending line extending approximately at right angles to the plug-in axis and with its entire edge resting as a locking disk on the inner wall of the base body cavity, with one Basic body adjacent conductor connection area, with a contact surface for the connector pin and with an encapsulated insulating material coating; the invention further relates to a device for producing such a socket.
  • Such sockets are mainly found in small device plugs, e.g. for shavers, use and must be well protected against the ingress of moisture and very often be connected to a corresponding plug pin and be detachable from it.
  • the insulating material sheath usually serves at the same time as a handle for connecting and disconnecting the plug connection, from which only the sheathed area of the connecting cable protrudes.
  • plug sockets are usually stamped in one piece from endless material webs and are subsequently produced from the blank (stamped part) by one or more bending processes.
  • the sleeve area of the plug socket, together with the contact area, forms a uniform cavity with a plurality of openings through which the insulating material penetrates when the socket is sheathed in an injection molding process and can thus also reach the contact area.
  • US-A-3 185 953 discloses a specially designed plug socket of the type specified at the beginning, in which a socket connection has a sleeve-shaped base body with a D-shaped cross section. This sleeve-shaped base body is followed by a conductor connection area which is in electrical contact with the stripped end of a cable. Both the sleeve-shaped base body and the conductor connection area with the stripped cable end are encapsulated with an insulating material jacket.
  • a cut-out partial surface of the base body is bent into the base body cavity and rests with its edge against the inner wall of the cavity in such a way that it acts as a locking disk.
  • a disadvantage of this known plug socket is that the blocking disk opens up at a high injection pressure of the insulating material and thus causes leaks. Leaks also occur if the circumferential contour of the locking disk is outside the tolerance limits. Finally, it is a disadvantage of the known plug socket that large radial forces are exerted on the already bent locking disk during the bending process with which the sleeve-shaped base body is produced, which can lead to deformations.
  • DE-B-2 507 328 discloses a coaxial connector with a molded insulating jacket.
  • a semicircular cut is made at the rear ends of the pins forming the connector and the corresponding section is bent to close the open rear end of the respective pin, so that no insulating material can penetrate into the interior of the pins during the spraying process.
  • the locking disk will be pivoted at high spray pressure, with the consequence that leaks will occur.
  • the locking washer must be tight against the inner wall of the pin without the presence of tolerances. Finally, large radial forces occur on the already bent locking disk during the bending process.
  • DE-C-2 428 582 discloses a socket for an electrical connecting line, in which electrical contacts are inserted in corresponding recesses in a sleeve, both the sleeve and the contacts subsequently being provided with an insulating material coating by a corresponding injection process.
  • US-A-3 081 497 discloses an apparatus for producing molded plastic parts in which workpieces are partially anchored.
  • the workpieces have a continuous bore through which the plastic material would pass during the injection molding process.
  • a spray aid in the form of pins is provided, which are firmly embedded in the casting mold and which close the through openings of the workpieces with their front tip.
  • the object of the invention is to further develop the known plug socket in such a way that it is possible to coat it with insulating material without problems, without the insulating material penetrating into the area of the contact surfaces despite the locking disk; in addition, a device for the simple manufacture of such sockets with an im Injection molding manufactured casing are provided.
  • the invention proposes that at least a portion of the edge of the partial surface be held in a groove provided in the inner wall of the base body and that the base body be arranged between the conductor connection region and the contact surface that can be pressed onto the plug pin.
  • the edge of the partial surface is held in a groove in the base body, particularly good sealing against sprayed insulating material is achieved.
  • tolerances between the partial surface serving as a locking disk and the base body can thus be absorbed.
  • Another advantage of this groove is that during the bending process with which the sleeve-shaped base body is produced, excessive radial forces are not exerted on the already bent-over part surface forming the locking disk; the groove can namely have an oversize, so that elastic, radial deformation forces are not or only incompletely transmitted to the locking disk on the outer wall of the base body.
  • the partial surface forming the locking disk has a hole which is concentric with the contact surface, this can serve as a centering aid for a spraying aid described below.
  • the cross-sectional area of such a hole is preferably smaller than the plug passage area spanned by the contact area; the edge of the locking disk surrounding the hole then serves to support the spraying aid in the axial direction.
  • the plug socket can be surrounded by a sleeve with a plug passage opening which is pushed over the base body in the plug-in direction and positively abuts against it.
  • the spring elements of the plug socket which have the contact surfaces on their inner surface are also kept free of the insulating material in the region of their outwardly facing surface.
  • no insulating material can then penetrate into the opening in the base body wall which is inevitably formed by the bending of the locking disk.
  • the use of the aforementioned sleeve is not absolutely necessary.
  • the decisive factor in ensuring that the contact surfaces remain free of the insulating material is the locking disk provided according to the invention, which prevents the insulating material from axially entering the socket from the rear.
  • the insulating material when radially penetrating into the socket, does not succeed in inserting itself between the contact surface and a plug pin inserted before the sheathing process.
  • the invention is achieved with respect to a device for producing the insulating material sheathing of a plug socket according to the invention in the injection molding process by a plug pin arranged in the injection mold coaxially to the plug axis of the plug socket and suitable for the plug socket as a plug-in aid.
  • This plug pin therefore covers the contact surfaces of the socket. This cover is maintained throughout the injection molding process.
  • the spraying aid has a conical end region outside the plug socket, this makes it easier to center the plug pin when it is inserted into the plug socket.
  • the spray aid preferably has a centering tip with an adjoining stop surface, the centering tip fitting into the hole in the partial surface of the plug socket forming the locking disk and the stop surface defining the axial end position of the spray aid.
  • the plug socket according to the invention and the device for its production, it has been possible for the first time to coat the plug socket with insulating material in a simple manner, in particular by injection molding, without the contact surfaces coming into contact with the insulating material.
  • a plug socket according to the invention has a sleeve-shaped base body 1 on which Sen end faces connect on the one hand a conductor connection area 2 and on the other hand a contact area 3.
  • the conductor connection area 2 consists in a known manner of a crimp area 4 for contacting a conductor wire 6 and a crimp area 5 for clamping an insulating jacket 7 of the conductor wire 6.
  • the contact area 3 has spring arms 8, the inner surfaces of which form the contact surfaces 9 for a plug pin.
  • the base body 1 can - as shown - consist of a cylindrical sleeve with a longitudinal slot 10.
  • Such a one-piece plug socket is produced by first punching out a corresponding surface pattern from a flat material and then bending it to form the plug socket.
  • the plug socket according to the invention now arises from the fact that, when punching out the sheet material in the area of the base body wall, a partial surface 11 is cut free in such a way that an area 12 of the edge of the partial surface 11 remains connected to the base body wall and the outline of the partial surface 11 corresponds to the inner cross section of the finished bent part sleeve-shaped base body 1 corresponds as closely as possible.
  • the area 12 forms a bending line which extends approximately at right angles to the plug direction E of the plug socket.
  • the partial surface is bent into the later main body cavity 13 by approximately 90 °.
  • the remaining base body wall is then bent into the sleeve-shaped base body 1.
  • the base body wall lies radially against the partial surface 11, which can now fulfill its function as a locking disk - as described below.
  • the plug socket can be surrounded by a sleeve 17 with a plug passage opening 18 which is pushed over the base body 1 in the plug-in direction E and positively abuts thereon; in this case the conductor connection area 2 can remain uncovered by the sleeve 17.
  • the plug socket which has already been crimped to the conductor, is inserted into a corresponding injection mold from one end and pushed onto a plug pin 19 serving as a spraying aid.
  • This connector pin seals the connector passage opening 18 and thus prevents the insulation material of the insulation jacket 20 from penetrating.
  • the spear disk 11 can have a hole 21 which is concentric with the surface spanned by the contact surface 9 perpendicular to the insertion direction E.
  • a plug pin 22 serving as a spraying aid is inserted into this hole with its centering tip 23 until a stop surface 24 of the plug pin 22 abuts the edge of the hole 21.
  • the plug pin 22 can be part of an injection mold 25, into which it is inserted coaxially to the intended plug-in axis 26 and from which it protrudes, beginning with its conical end region 27.
