Definitions

• Plug for use in a distributor of a telecommunications network
• the invention relates to a connector for use in a distributor of a telecommunication network, in particular in a main distributor of a public telephone exchange, the distributor being provided with closely spaced contact components into which the low-pole connector, for. B. for testing purposes and can be connected to a subscriber line.
• plugs must be able to be inserted tightly into the contact components in both coordinate directions.
• the plug With the anti-kink grommet extending in the plugging direction, the plug has a flat, elongated shape, which enables the plug to be plugged in and unplugged even in a very dense arrangement. This dense arrangement is given in particular in the case of contact components which are connected to electronic test devices and are spatially at the
• the invention is based on the object of being able to remove the connecting cords from the plug as closely as possible against the distributor.
• the plugs with the subsequent cord sections project far less from the outside of the distributor.
• the grommet protrudes into the plugging and pulling area of the next plug, it can no longer be easily inserted or removed.
• the spout is made sc elastic. that it can be bent out of the area of the neighboring plug. This can now be inserted or removed freely. If there is enough free space on the side of the plug, it is also possible to bend the grommet sideways in addition to the extension so that the plug underneath can be pulled out even more easily.
• the spout is bent up by pulling the connecting cord. However, since this plug should not be pulled, the clamping bars ensure that it remains firmly anchored in its functional position.
• the use of elastomeric material increases both the bendability of the grommet and the deformability of the clamping webs.
• FIG. 1 is a perspective view of a test cord with two connecting plugs which have a curved kink protection sleeve
• FIG. 2 is a side view of several plugs according to FIG. 1 inserted one above the other into a contact component of a distributor, .
• a plug 1 with three plug tongues 2 lying in one plane is connected to a connecting cord 3 which is connected at its other end to a further plug 1.
• An anti-kink sleeve 4 with circumferential transverse grooves 5 is attached in one piece to the housing of the plug 1.
• narrow clamping webs 6 are formed on the housing in the immediate vicinity of the tongues in the plugging direction.
• the housing is made of elastomeric material, so that the grommet and the clamping webs are elastically deformable.
• the kink protection sleeve 5 is curved. The line of curvature lies in the plane of the tongues. The kink protection sleeve 5 protrudes laterally beyond the corresponding side surface of the plug.
• connection elements 8 to which, for. B. incoming from the participants and outgoing to the switching system 9 are connected.
• the connection elements are connected to contact springs 10 projecting into the interior of the contact component 7, between which the plug tongues 2 of the plug 1 are inserted so as to make contact.
• the kink protection sleeves 4 are so long and so strongly curved that they protrude into the plug and pull area of the adjacent plug 1. However, they are so elastic that they can be bent out of this area.
• the clamping webs 6 give this connector such a good hold in the contact component that it is not loosened.
• the deformability of the anti-kink sleeve 4 is increased by the fact that the innermost of the transverse grooves 5 is attached to the housing of the connector 1 at an angle to the direction of insertion.
