Definitions

• the invention relates to a connection device according to the preamble of claim 1.
• connection devices are known in various designs. They can be designed in single or multi-pole design.
• the determination of the electrical conductor is screwless by means of at least one compression spring.
• marking elements are advantageous or possibly even necessary, which have a printable or otherwise inscribable marking surface.
• Their arrangement on the connection devices or in the vicinity of the connection devices is often a problem, since the available space is very limited.
• the invention has for its object to solve this problem.
• the marking devices are arranged in a particularly space-saving manner on the actuating element of the connecting device.
• the invention is particularly suitable for actuators of connection devices in direct plug-in technology.
• it is particularly advantageous since just when the connection devices are designed for conductors of small cross-section, only little space for attaching markers or marking devices is present.
• the actuators provide an existing advantageous location for attaching the marking. Because the space on the actuator is used almost twice: on the one hand for the actuation function and on the other hand for the marking function. By the marking function, the operability of the Huaweisteckan gleiches is not hindered.
• marking devices on actuators of connection devices in other connection technology, so in particular to actuators of tension spring terminals or IDC terminals.
• each male member is cylindrical according to a preferred embodiment, wherein the base diameter of the cylinder is smaller than the inner diameter of each insertion channel, and wherein the shaft of each male element has at least one plastically deformable securing web, which at least over extends the end portion of the shaft.
• the basic diameter is to be understood as meaning the diameter of the solid shaft on which the securing web or webs are formed.
• Alternative embodiments of the cylinder shape are conceivable: e.g. a square or otherwise polygonal cross-section.
• Each securing ridge extends in the longitudinal direction of the shaft.
• each insertion channel has a free space on the side facing away from the head of the attached plug-in element.
• An optional positive connection between the actuating element and the head on their mutually facing sides ensures an anti-rotation between the head and the actuating element.
• each head of the plug element on the side facing the actuating element has at least one molding web, which rests on the outer surface of the actuating element in a corresponding Formstegement.
• the cross section of the molding web is trapezoidal.
• the plug-in elements are made of plastic by injection molding using appropriate tools.
• connection device 1 shows a connection device in a perspective view
• Figure 2 shows a detail in the adjoining the insertion channel area in a sectional view
• FIG. 3 shows the marking and plug element used in an actuating element in cross section.
• connection devices 4 for conductors are designed here as direct plug-in terminals.
• Direct plug-in terminals are known, for example, from DE 20 2010 008 028 U1. They each have at least one preferably V-shaped clamping spring 5, which is formed in a clamping cage 6 - for example, inserted into this - is.
• the clamping spring 5 has a clamping leg 7, which is designed to press a conductor in the region of a clamping point 8 against an inner wall 9 of the clamping cage or against a busbar.
• connection devices 4 and the female contacts connected to these are inserted into a housing 10.
• This housing 10 is provided with a plurality of side by side and one above the other arranged ladder insertion channels 1 1, in which the conductors (not shown here) in the
• Clamping points 8 are inserted.
• Each connecting device 4 is associated with an actuating element 12, which serves and is designed to depress the clamping leg (in conductor insertion X) to open the clamping point 8, for example to
• the actuating element has a plug-in channel, in this case a plug-in channel 13 extending in or parallel to the conductor insertion opening and designed as a passage opening, which passes through the actuating element in the plug-in direction X.
• each connection device 4 is further associated with a marking device M, which is designed as a plug-in element.
• a marking device M which is designed as a plug-in element.
• the exact shape of the plug-in elements results from the figure 1 in conjunction with the figure 3.
• each plug element consists of a head 14 and a shaft 15.
• the shaft 15 is cylindrical here, while the head 14 is square in the present embodiment.
• the shaft 15 of the plug element M is provided with a plurality, here three longitudinally extending securing webs 16, wherein the base diameter of the shaft 15 is smaller than the diameter of the Einsteckkanales 13.
• each male element M with a certain Force in the insertion channel 13 are introduced.
• the shape and material springing properties of plastics are exploited, so that a positive fixing of each plug element M takes place.
• a free space 17 is then provided following each insertion channel 13.
• FIG. 1 shows that each plug-in element M or the head 14 of each plug-in element M has at least one molding web 18 on the side facing the housing 10, which in cross-section is preferably trapezoidal in shape.
• these forming webs 18 engage in correspondingly shaped mold web receptacles 19 in the side of the actuating element 12 facing the head 14.
