Definitions

  • the invention relates to an electrical connector, as is known in part from DE 37 25 261 A1.
  • a U-shaped spring clip made of wire serves as a detent spring.
  • the latching spring can be brought from a locking position into a release position via a loop which extends approximately in the plugging direction and which is supported on the housing.
  • the detent spring is either spread out, see FIG. 3, or moved, see FIGS. 6 and 8.
  • DE 31 23 825 C2 from which the invention is based in the preamble of claim 1, already shows an improvement in the case of a detent spring designed as a spring clip: there a button is formed on the housing, by means of which the spring clip can be expanded.
  • the button can be designed as a push button or toggle button, which can cause the spring clip to spread either alone or with the same second button.
  • the spring clip is stored in the housing and the closing force is ensured by clamping the spring clip to the housing base body.
  • the key or keys only serves to spread the spring clip.
  • a shielded plug is known from EP 0 351 083 A2, in which two lateral, tiltable sheet metal springs ensure locking with a mating plug. Each free arm of the sheet metal springs has a button. By pressing both buttons simultaneously, both sheet metal springs can be tilted so that the lock is released. However, 2 detent springs and 2 buttons are required here, which must be pressed simultaneously.
  • the invention is based on the endeavor to create an electrical connector of the type mentioned, in which the spring is as simple as possible to form and yet a strong locking and easy, easy release are ensured.
  • the invention proposes that in the case of a plug of the type mentioned at the beginning, the detent spring is positively attached to the button and the locking sections are displaceably guided in the housing.
  • the invention takes a different path than the prior art: the invention first dispenses with a spreading of the detent spring, which requires a greater effort than mere displacement. At the same time, the invention completely dispenses with the fact that any spring forces of the detent spring have to be overcome in order to release: the function "holding" the detent spring on the housing is performed by the housing, more precisely: the release button molded onto the housing. As a result, the detent spring can be shaped very simply, but at the same time it can be very strong, that is to say with a large spring constant for the detent functions.
  • the detent spring is positively attached to the button with its U-web, a wide and stable storage is ensured, especially with very wide springs.
  • the stability is further increased if the U-web is bent in a meandering shape and is inserted into the slots of the key in such a way that at least a section of the U-web extends over and at least a section of the U-web extends under the key.
  • the detent spring is easy to install if the edges and / or the slots of the key are provided with chamfers or curves for the corresponding sections of the U-web of the detent spring. Then the detent spring can be easily pushed into the side of the button.
  • the housing can have guide slots for the detent spring and these guide slots can widen towards the button.
  • a wide button and consequently no tilting of the catch spring is achieved if the button or its grip plate is at least almost as wide as the U-web of the catch spring. Then, with a relatively wide connector, several fingers can attack the button.
  • the largest possible flat top of the button is formed if it comprises a handle plate with a relatively wide central section, under which a central section of the detent spring is arranged, and two relatively narrow outer sections, over which two outer sections of the detent spring extend, and that the two downward locking arms connect to the two outer sections.
  • the key can be connected to the housing in the simplest case via a strong film hinge or the like.
  • the button can be molded onto the housing via two or more elastic bridges.
  • Figure 1 shows an electrical connector 1 with a housing 2 made of plastic with two contact and line chambers 3, which are used to hold, if necessary, sealed contact parts, such as. B. sockets, serve.
  • a housing 2 made of plastic with two contact and line chambers 3, which are used to hold, if necessary, sealed contact parts, such as. B. sockets, serve.
  • an elastic rubber seal 6 is inserted in an annular space 5, which serves to seal a mating connector 7 to be inserted.
  • the housing 2 is formed on the top 8 via two elastic bridges 9, a symmetrically designed button 10.
  • the bridges 9 are based on a reinforcement 11 of the housing 2 and continue towards the front, towards the plug side 4.
  • the bridges are initially designed in the form of part circles, cf. FIG. 1, form two webs 12 and then unite near the plug-in side 4 to form a handle plate 13.
  • the handle plate 13 extends almost parallel or only slightly angled to the housing 2.
  • the handle plate 13 is almost as wide as the housing 2 and has three sections towards the plug side 4: a central section 14 and two lateral, outer sections 15, with short slots 16 in between, which emerge from the handle plate 13 towards the plug side 4.
  • the middle section 14 has a downward-facing guide bevel 18 on its plug-side edge 17.
  • Corresponding upward-pointing bevels 19 can be found on the sections 15. In the region of the slots 16 and on the outside of the sections 15, the corresponding edges R1 and R2 extending in the plug-in direction are rounded.
  • a space 20 for receiving the housing of the correspondingly shaped mating connector 7 extends toward the mating side 4.
  • the side walls 21, the bottom 22 and the top wall 23 comprise the space 20.
  • the mating connector 7, compare FIG. 1, has approximately the outer cross-sectional shape as that Room 20, see also FIG. 2.
  • recesses 24 and 25 are made in the floor 22 and in the ceiling wall 23.
  • grooves 26 which extend transversely to the direction of insertion and which are connected to grooves 27 which run within the space 20 along the direction of insertion, see FIG. 2 on the left.
  • a symmetrical locking spring 28 made of spring wire is used to lock the connector 1 with the mating connector 7, see FIG. 2.
  • the locking spring 28 has the shape of an inverted U, with a particularly curved U-web 29.
  • the U-web 29 has a central one the U-arms 30 offset middle section 31, two obliquely adjoining sections 32 and two parallel outer sections 33 extending to section 31.
  • the downwardly angled U-arms 30 connect to the outer sections 33.
  • the U-arms 30 end as locking sections 34 shaped into an eye.
  • the sections 34 have a U-shape or an almost closed O-shape, see FIG. 2.
  • the detent spring 28 is assembled as follows: from above, the two locking sections 34 are inserted into the grooves 26 until the U-web 29 hits the key 10. Then the U-web 29 is bent so far towards the insertion direction that it can be inserted from the edge 17, ie laterally, with the sections 32 into the slots 16 of the key 10. Here, the guide bevels 18 and 19 and the curves R1 and R2 facilitate the positive insertion and clamping of the U-web 29. After insertion, the middle section 31 is below, the outer sections 33 of the detent spring 28 above the handle plate 13 of the button 10, see also FIGS. 3 and 4. The locking sections 34 are located in the slots 26 at the level of the grooves 27, see FIG. 2 on the right.
  • This position is the basic position of the detent spring 28 and at the same time its locking position. If the mating connector 7 is inserted into the space 20 in this position, compare FIG. 1, the electrical contacts (not shown) are connected to one another and two lateral projections 35 of the mating connector 7 are inserted into the grooves 27 of the connector 1. During insertion, bevels 36 on the projection 35 laterally push the parts of the locking sections 34 projecting into the grooves 27 laterally out of the grooves 26 until these locking sections 34 snap back and behind the projections 35 and come to rest on a locking surface 37, see also Figure 3.
  • FIGS. 5 and 6 show two configurations which further facilitate the assembly of the detent spring 28.
  • the middle section 14 'of the handle plate 13' is shorter by the dimension X than the outer sections 15 '. This makes it easier to push the central section 31 'of the detent spring 28 under the central section 14' of the handle plate 13 ', since the detent spring 28 no longer has to be bent as much in the areas of the U-arms 30 as described first.
