Definitions

• the invention relates to a connector assembly for an electrical or optical cable.
• Typical applications for such connector assemblies are used in the optical and / or electronic network termination technology in office equipment, such as Ethernet as a network and RJ45 or RJ 1 connector type 1 connectors.
• the terminal end of such cables used for connectors is now subject to a strong standardization.
• FIG. 6 A standardized embodiment is shown in FIG. 6.
• the connector body is assembled using known assembly technology at the end of the cable.
• a mechanical lock is provided, which is to be opened by a manually operable bolt tongue 112 when the connector body, inserted into a socket to be released from this.
• the depressed Rieglzunge triggers the connector body by means of locking hooks 115 from the connection with a connector body complementary complementary body (socket).
• the connector body are enveloped by a housing made of insulating material, with parts of the housing cover the lock.
• the housing should primarily serve the contact protection and may comprise further means for fastening the connector body to a trained example as a stuffing box connection part with which the cable to a device in which the complementary counter body is arranged, can be connected.
• Various connector assemblies are available in the market which have different configurations of the insulating housing and / or mechanical interlocking actuators.
• Such connector assemblies show certain disadvantages with regard to the handling of the actuators. For example, that they are arranged so that they are difficult to access in the inserted state of the plug, because they are very close to the device surface. As a result, the user is sometimes forced to use a tool in addition, which in the case of a single case in the absence of a suitable tool can sometimes be a toothpick. Another disadvantage is observed in that the housing of the connector body is not completely closed in the region of the actuators. There are windows there that contradict the demand for insulation. Such connector assemblies fail when tested for dielectric strength and impermissible creepage distances.
• the invention is therefore based on the object to further develop a connector assembly in which the operation for mechanical unlocking is safe and easy, and which has a high dielectric strength.
• the actuating element consists of a parallel to the plug-in direction formed pressure body, which has at least one in the
• Housing trained surface element is connected to the housing, and the actuating element comprises a pressure part for manual actuation.
• the actuator is characterized by a particularly long lever arm.
• the housing of insulating material is easy to manufacture, since the molding can be formed in the casting or injection molding tool.
• the at least one surface element forms the outer surface of the insertion slot for the bolt tongue.
• the at least one surface element is formed in the housing with reduced material wall thickness and connected to a film hinge in the housing.
• the at least one surface element has a breakthrough.
• the housing is formed covering the connector body within the opening.
• Figure 1 view of a first embodiment of the housing
• Figure 2, 3 views of a second embodiment of the housing
• Figure 4 a section through the housing without connector body
• Figure 5 a section through the housing with prefabricated plug body
• Figure 6 a typical embodiment of a cable end.
• a housing for connector assemblies for an electrical or an optical cable is shown.
• a complete arrangement comprises a connector body 110 designed as a socket or plug.
• the surface of a connector body is usually metallic or consists of a metal shell, whereby a conductive, potential-free connection between the plug and socket can be produced.
• a prefabricated connector assembly is shown schematically, which is plugged into a device.
• a device is to be understood here a device of any kind, so for example, a circuit board, a cable channel, a telephone and / or an electronic device. From the device, the device edge or surface 60 and the insertion opening 62 for the plug can be seen. Approximately at the front edge 114 of the connector body 110, the locking tongue 112 is articulated. In Fig. 5 is also particularly recognizable that the length L of the bolt tongue 112 is not longer than the depth of the plug opening 62. The bolt tongue is drawn in its relaxed position, as it would be if no connector body 110 would be inserted. It will be appreciated that after the connector body 110 has been inserted, the bolt tongue will be depressed by the element 12.1 to be described later.
• the assembly can for example be done by crimping and attachment with a device can be applied, for example, a female connector.
• the connector assembly has a rectangular cross-section in the illustrated embodiments. However, the arrangement can also be designed for plugs with a round cross-section.
• the proposed arrangement has an insulating material housing 100 for the connector body 110.
• the insulating material may be a rubber elastic plastic.
• a latch tongue 112 which serves to block the release of the connector body 110 from a designed as a plug or socket to the connector body 110 complementary body 120.
• the length L of the bolt tongue is dimensioned such that it is not longer than the depth of the insertion opening.
• a resilient actuating element 12 for actuating the locking tongue 112 is arranged on the housing 100.
• the actuator has a particularly long lever arm, whereby the pressing down of the bolt tongue 112 is greatly facilitated.
• the element 12 is integral with the housing 100 and formed deformable with this.
• the actuating element 12 consists of a pivot point 16, designed as a grip bead pressure part 14 (for manual actuation to release the mechanical lock) and from a parallel to the insertion direction formed pressure body 12.1.
• the said parts of the actuating element 12 are integrally formed with the housing and thus virtually integrated in the housing.
• the articulation point 16 (as the root of the web 15) is located near the cable entry opening 11 between the articulation point 16 and formed as Griffwulst pressure part 14 is an obliquely rising web 15 is provided, which serves to rest a finger of a user during unlocking (see FIG 2).
• Web 15, handle bead 14 and the pressure body 12.1 lie in a line and form a relatively rigid unit.
• the elasticity and mobility of this unit is achieved by the hinge 16 formed as a film hinge. The mobility is supported by the reduction of the material thickness of the mutual surface elements 17th
• the two illustrated embodiments differ in that, according to FIG. 1, the mutual surface elements 17 in the housing are closed on all sides and, as shown in FIG. 3, the surface elements 17 have an opening. Both embodiments need not necessarily differ in their flexibility, if the stiffness of the material of the housing and the material thickness of the surface elements 17 are formed differently depending on the application.
• Surface elements 17 are present on both sides of the insertion shaft 104 for the bolt tongue 112 and form the outer surface thereof. As already mentioned, the surface element 17 is formed on both sides in the housing 100 with reduced material wall thickness.
• an opening 105 is present, however, the housing 100 is closed inside the opening. There, the connector body 110 is covered. As a result, the connector assembly is maintained a high insulation. Also, IP protection requirements are met because there is no window through which the surface of the connector body 110 is accessible.
• the present invention is not limited to the embodiments described above, but also includes all possible embodiments of the invention. These may differ in the cross-sectional shape of the connector assembly, not limited to connector types we RJ45 or RJ11. Likewise, the proposed arrangement is applicable to optical as well as electrical connectors.
