Angled plug connector with shielding

Abstract

An angled plug connector has an insulating housing made of plastic and a two-part shielding, consisting of a first (upper) shielding sheet and a second (lower) shielding, the shielding sheet being formed in one piece or in one part. The shieldings are at least partially arranged in the interior of the insulating housing. The shieldings can be easily stamped from a metal sheet, cut, then bent and inserted into the insulating housing.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

(7) An angled plug connector 1 according to the invention is shown in FIG. 1. This is designed as a kind of adapter bushing/receiving housing for a corresponding plug (not shown).

(8) The plug connector 1 has an insulating housing 2 made of plastic. The insulating housing comprises an upper wall 20, a lower wall 21, and side walls 22a, 22b. The upper wall 20 has a flat, planar outer side. This enables suction for handling the housing 2 during assembly. The walls delimit a receiving space for the corresponding plug. In addition, the insulating housing 2 has a block 23 which determines the plug face. The block 23 separates or insulates contact elements 3 of the plug connector 1 therein and plug-in contacts of the corresponding plug from each other therein. In this embodiment, the contact elements 3 of the plug connector 1 are formed as a contact blade or contact springs or combinations of the two. In addition, the plug connector 1 has a multi-part shielding, consisting of a first (upper) shielding sheet 4 and a second (lower) shielding 5. The shielding sheet 4 is formed as one piece or one part. The lower shielding 5 can be in one piece. However, it can preferably consist of two or more segments or shielding sheets arranged next to each other, as represented below in FIG. 2. The shieldings 4 and 5 are at least partially arranged in the interior of the insulating housing 2. The first shielding sheet 4 extends in sections along the inner side of the upper wall 20, the second shielding 5 along the inner side of the lower wall 21.

(9) In FIG. 2, only the insulating housing 2 and the shieldings 4 and 5 are shown, in a separated state. The first shielding sheet 4 is designed as a stamped and bent component or metal sheet. The second shielding 5 consists of two stamped and bent components or metal sheets 5a and 5b arranged next to each other. The shieldings 4 and 5 can be easily stamped from a metal sheet, cut and then bent.

(10) The first (upper) shielding sheet 4 has a first shielding section 40 and a second shielding section 41 angled at right angles thereto. The first shielding section 40 is inserted during assembly in the insertion direction E into a corresponding receptacle 24 in the insulating housing 2. The second shielding section 41 forms the rear side of the angled plug connector 1. Fastening tabs 42a, 42b extend forward on both sides from the second section 41. The fixing of the first shielding sheet 4 takes place by inserting the tabs 42a, 42b into corresponding recesses 25a and 25b of the insulating housing 2. The first shielding sheet 4 has contact feet 43 to create an electrical connection to ground contacts of a printed circuit board 6, as shown in FIG. 3. Spring tongues 400, which are produced by punching and crimping of the metal sheet, are formed in the first shielding sheet 4 to produce a secure electrical contact with corresponding contacts of a corresponding plug. If the insulating housing 2 has a vertical reinforcing wall (not represented) for stabilizing the housing 2, the first shielding sheet 4 can be guided by a slot 401 formed in the first shielding section 40.

(11) The second (lower) shielding sheets 5a and 5b are constructed similarly to the first (upper) shielding sheet 4. The second shielding sheets 5a and 5b each have a first shielding section 50 and a second shielding section 51 angled at a right angle thereto (only indicated on the lower shielding sheet 5a by way of example). The latter section 51 is substantially shorter than the second shielding section 41 of the first shielding sheet 4 for geometrical reasons. Its height or length depends on the geometric conditions, namely substantially the distance of the first shielding section 50 from the contact points of the printed circuit board 6. If it makes sense for geometrical reasons, the second shielding section 51 can also be missing or have a height of zero. Then, contacts 53 extend at an angle directly from the first shielding section 50 toward the printed circuit board. The first shielding section 50 is inserted during assembly in the insertion direction E into a corresponding receptacle 26 in the insulating housing 2. One of the fastening sections 52 is represented in FIG. 4. The fastening sections 52 are formed as stamped and crimped tongues. During assembly, they are inserted and fixed in corresponding recesses 27 of the insulating housing 2. The second shielding 5 is thus fastened to the insulating housing 2. The fixation takes place in particular by over-pressing, that is, the recesses 27 on the insulating housing are slightly narrower than the fastening section. The result is a frictional connection.

(12) Spring tongues 500, which are produced by punching and crimping of the metal sheet, are formed in the second shielding 5 to produce a secure electrical contact with corresponding contacts of a corresponding plug. The structure can repeat along the front edge of the second shielding 5. The second shielding 5 has contact feet 53 for establishing an electrical connection to ground contacts of a printed circuit board 6, as represented in FIG. 3. If the insulating housing 2 has a vertical reinforcing wall (not represented) for stabilizing the housing 2, this can be guided by a slot 501 formed in the first shielding section 50.

(13) The insertion during assembly takes place for all shielding sheets 4, 5a and 5b in a uniform insertion direction E from the back side 1001 or the connection side of the plug connector 1 (the back side 1001 is the side opposite a plug side 1003 comprising the plug face). The plug connector 1 in the assembled state is represented in FIG. 3 (parts of the insulating housing are omitted in the illustration). In particular, the design and arrangement of the contact elements 3 are shown. These have contacts 30, which are arranged in the plug face in rows next to each other or one above the other. In addition, the contact elements 3 have bent contact sections 31, the ends of which contact corresponding contacts 60 of a printed circuit board 6. The contacts 31, 60 are also arranged next to each other in rows and columns During assembly, the second shielding sheets 5a, 5b, the contact elements 3 and the first shielding sheet 4 are inserted from the back side into the insulating housing 2 in the sequence.

(14) FIGS. 4 and 5 show details, in particular of the second shielding 5, comprising fastening sections 52 which are arranged between contact tongues 500. While the fastening sections 52 protrude into recesses 27 of the housing 2, the contact tongues 500 are bent upwardly to establish good contact with corresponding mating contacts of a corresponding plug. It is clear from FIG. 5 how the contact tongues 500 are produced by punching and bending of the metal sheet.

(15) The fastening and fixation of the upper shielding sheet 4 can be done in the same way. The structure of the front edge of the upper shielding sheet 4 therefore substantially corresponds to the structure of the front edge of the lower shielding 5.

(16) Both manufacturing and assembly of the plug connector 1 are simple, since parts of the shielding 4, 5 are merely stamped, bent and inserted into the insulating housing 2.
