Electrical plug connection

The invention relates to an electrical connector, in particular an improved electrical connector, Their plastic plug and coupling housings can be easily separated from one another by hand.

The prior art knows electrical multiple plug connections with molded plastic housings and contact pairs that come into engagement with one another. In US patent 3,178,673, for example, a "wire connection" and in U.'J patent 3,465,279 a "miniature pin connection"

the housings are very smooth, so that it is difficult for the surgeon to grip the housing halves firmly, to pull them apart when his fingers are wet from perspiration, especially when the forces of touch between the pins and the sockets are large so that considerable pulling force is required is to separate the contacts from each other.

The object of the invention is to provide an easily separable electrical unit To propose plug-in connection with pins and sockets, which is equipped with means that lock the two halves of the housing together and with the help of let your finger loosen to separate the two halves of the housing.

According to FIG. 1, an embodiment of an electrical plug connection IO consists of a plug 12 and one Coupling 14. The coupling consists largely of a rectangular, molded housing made of a thermoplastic Plastic, e.g. nylon. Me coupling 14 has a housing 16 and a forwardly extending insertable End 18. The end 18 has two chamfered edges 20, with the aid of which the coupling 14 relative to the plug 12 is oriented. The coupling 14 is equipped with several cylinders which have bores 22 in which Contact sleeves are arranged. These contact sockets correspond largely to the contact sockets described in US Patents 3,178,673 and 3,465,279.

The front end 18 of the coupling 14 is equipped with a cam surface 24, the rear end of which is a right-angled Has shoulder 26 which forms part of a lock that is connected to the locking means of the Connector 12 can be brought into engagement. Me coupling 14 has fastening hooks that protrude outwards at right angles equipped. The attachment hooks 28 are the same as those described in U.S. Patent 3,196,380. they are equipped with transverse grooves 30. As described in US Patent 3,196,380, the hooks 28 can be parallel to the adjacent ones Fold back the side walls of the coupling 14 so that the adjacent edges of a chassis are in the transverse grooves 30 can be lighted up. It is evident that the hooks 28 are on the sides of the coupling 14 located at right angles to the sides to which locking means 24 and 26 are attached are. It is also evident that wires 23 which bond to the sockets v * ″ are the housing 16 on its rear side leaving.

The plug 12 "also has a largely rectangular one Housing 34 and a slightly enlarged front end 36 with a recess 38 which is shaped so that it can accommodate the front end 18 of the coupling 14. The recess 38 has two chamfered edges 40 equipped, which are complementary to the chamfered edges 20 of the coupling 14, so that the two halves of the Let the plug connections correctly orientate relative to each other. In the plug 12 contact pins 42 are arranged, which protrude into the recess ^ 8. This arrangement of the Contact pin 42 is described in U.S. Patents 3,178,673 and 3,465,279. Wires 44 that connect to the contact pins 42 are connected, leave the housing 34 of the plug 12 at its rear.

A locking element in the form of an elastic tongue 46 is arranged longitudinally on the front end 36 of the plug 12 and through edge slots 48 from the front end 3b separated. The free end of the tongue 46 has an angled portion 50 which is designed so that when they are joined together of the plug 12 and the coupling 14 slides over the cam surface 24 so that their rear edge 54 interlocks snaps behind the shoulder 26.

The bend 50 can easily be grasped and lifted with one finger, so that the plug 12 and the coupling 14 can be separated from one another. However, as previously described, the molded plastic housings tend to be somewhat slippery. Therefore, according to the invention, the housing 34 of the plug 12 is equipped with fins 5b which protrude outward from opposite side walls 58 in opposite directions. The side walls ¹ Ai are arranged at right angles to the side band.

net, which is equipped with the tongue 46. The side walls 58 have a thickened central part 60 in front of the fins 56 and behind the fins for stiffening purposes a longitudinal rib 62. The fins 56 are somewhat tapered as shown in Figure 1, i.e. they are narrower at their outer end than at their fortified end. Furthermore, the attached end is at its front for additional stiffening equipped with a fillet radius 64.

If the plug 12 and the coupling 14 are to be separated from the position shown in FIG. 3, the The clutch 14 is gripped with the left hand, with the thumb and forefinger under the hook 28. Of the The thumb and middle finger of the right hand then grip the fins 56, while the index finger of the right Hand flexes the bend 50 of the tongue 46 outwardly, ho that it comes free from the shoulder 26 during the Plug 12 and the coupling 14 apart in the longitudinal direction to be pulled. In FIG. 5, the tongue 46 is shown in dashed lines Lines in the bent outward position and in solid lines Ln the locking position tellurig
