Definitions

  • the invention relates to a plug-in print terminal with an insulating housing according to the features of the preamble of claim 1.
  • the invention has for its object to provide a print terminal of the aforementioned type, the contact part is easier to manufacture.
  • the contact piece and the clamping spring consist of a single part, namely the only bent transversely to its longitudinal extent flat ribbon.
  • the peculiarity of the leg spring formed by the metal band lies in the fact that it contacts the connected conductor only with its clamping leg, which is clamped by the clamping leg against the clamping abutment formed by the insulating housing.
  • the more or less punctiform or linear contact point between the clamping leg and the clamped conductor is in any case sufficient if only relatively small currents flow over the metal ribbon.
  • FIG. 1 shows in detail an insulating housing 1, which is designed as an arrayable, disc-shaped housing in a narrow design.
  • the housing 1 has a width of 2.5 to 3.5 mm. with a maximum length of 15 mm.
  • a current-carrying contact piece 3 is arranged, which has two spatially separated contact points, as will be discussed below.
  • the contact piece 3 consists of a metal ribbon 2, which is bent several times exclusively transverse to its longitudinal extent. It is a flat band 2, which has a constant width over its entire length.
  • a spring tulip 4 is formed from the metal flat band 2, which is arranged in a terminal space 5 of the insulating housing 1.
  • the spring tulip 4 is the contact element for a bottom side existing on the insulating housing 1 plug connection 6, with which the print terminal can be plugged onto a contact pin 7.
  • a contact pin 7, as he also made FIG. 3 is firmly on a printed circuit board, which is not shown in the drawing, arranged and provided with a plastic block 32, via which it is supported on the circuit board.
  • the plastic block 32 In the inserted position is the plastic block 32 in a receiving space 33, which is located in the region of the bottom-side plug connection 6 of the insulating housing 1 and is open towards the underside thereof.
  • To the receiving space 33 includes a pin guide 8, which consists of a cylindrical passage opening which connects the receiving space 33 and the contact space 5 with each other and the passage of the contact pin 7 is used.
  • the contact space 5 is an elongated space which extends in the insertion direction of the contact pin 7.
  • This corresponds to the elongated shape of the spring tulip 4, which firstly consists of a spring leg 9, which is formed by one of the two ends of the flat strip 2.
  • the spring leg 9 is connected via a bending joint with an arc of more than 180 ° in a support leg 11, which bears against an inner wall of the insulating housing 1. Therefore, when the penetration of the contact pin 7, only the spring leg 9, the spring tulip 4 dodge, for which in the contact space 5, a free space 12 is provided, in which the spring leg 9 of the spring tulip 4 can spring open.
  • the insertion of the contact pin 7 in the spring tulip 4 is facilitated by a weggebogenes from the support leg 11 9.1 of the spring leg.
  • the bending joint 10 of the spring tulip 4 is located on the pin guide 8, to which the spring tulip 4 opens when einschiebendem contact pin 7.
  • the support leg 11 of the spring tulip 4 extends in a direction straight to the direction of insertion of the contact pin 7 parallel direction, and it is the on the spring tulip 4 inner side of the support leg 11 in a tangential direction to the pin guide eighth
  • the metal ribbon 2 has two bends 13 and 14 at an angle of 135 °, over which the support leg 11 merges into a bearing leg 16, which is part of a leg spring 15 formed by the flat band 2.
  • the bearing leg 16 of the leg spring 15 is perpendicular to the support leg 11 of the spring tulip 4, which is not mandatory.
  • To the bearing leg 16 of the leg spring 15 includes a bending joint 17 and a clamping leg 18 thereto. In the non-clamping starting position, the bending joint 17 has a 180 ° arc and is the bearing leg 16 bent back towards clamping leg 18 with this parallel.
  • the leg spring 15 forming portion of the flat strip 2 is disposed in a terminal space 19 of the insulating housing 1, wherein the bearing leg 16 is fully supported on a side facing away from the bottom side of the housing 1 wall of the clamping space 9 with its side remote from the clamping leg 18 side.
  • the terminal space 19 there is a wedge-shaped stop 20 with a non-deflected clamping leg 18 inclined top, on which the clamping leg 18 runs at deflection in order not to overstretch the leg spring 15 can.
  • the flat strip 2 With its second end, the flat strip 2 forms a clamping end 21 on the clamping leg 18, which cooperates with a clamping abutment 22.
  • the clamping abutment 22 is projecting from a in the terminal space 19
  • Clamping rib 23 of the insulating housing 1 is formed, and this clamping rib 23 with its clamping abutment 22 extends at an inclination angle of 45 ° to the insertion direction of the contact pin 4.
  • a conductor guide channel 24 in the insulating housing 1 To the clamping abutment 22 out leads with the same inclination a conductor guide channel 24 in the insulating housing 1, in particular FIG. 2 clarified.
  • a conductor connection opening 25 merging into the conductor guide channel 24 is provided at the top of the insulating housing 1, a conductor connection opening 25 merging into the conductor guide channel 24 is provided.
  • FIG. 2 can be seen on the basis of the conductor 24 shown there obliquely to the direction of insertion of the contact pin
  • a guide channel 26 is formed between the conductor guide channel 24 and the contact space 5, which receives the spring tulip 4, which extends parallel to the insertion direction of the contact pin 7.
  • a handle 27 is slidably mounted in the guide channel 26, whose inner end 28 is made so narrow that it, as FIG. 2 shows, in the depressed position of the pusher 27 on the clamping rib 23 past the terminal end 21 is applied to the clamping leg 18 of the leg spring 15. This is possible because the clamping rib 23 covers the clamping end 21 of the clamping leg 18 only in part, preferably by more than half.
  • the pusher 27 has a adapted to the placement of a tool blade 35 actuating end 29. Another peculiarity of the pusher 27 is that it is in the in FIG. 1 shown Position, the not yet actuated starting position, is molded onto the insulating housing 1.
  • the still existing connecting webs to the insulating housing 1 out are designed as breakaway webs, which are severed at first actuation of the pusher 27.
  • the pusher 27 is latched in its seated on the clamping end 21 of the clamping leg 18 position, which happens in the open design of the insulating housing 1 to the adjacent neighboring housing.
  • FIG. 3 Finally, there is a notch 31 as well as a locking cam 36, which serve to secure the contact piece 3 formed in the flat band 2 in the insulating housing 1.
  • a positioning rib 30 which projects into the clamping space 19 and engages positively in the notch 31 on the bearing leg 16 of the leg spring 15.
