Description

Technical Field

[0001] The present invention relates to an angled plug connector comprising an insulating housing, an angled contact element for establishing a connection between a corresponding plug and a printed circuit board, and a first shielding and a second shielding forming a shielded channel. In addition, the present invention relates to a method for producing such an angled plug connector.

Background Art

[0002] Angled plug connectors for connection to a mating plug and to a printed circuit board are known in different designs. Such angled plug connectors may have an insulating body for insertion into a bushing insulating housing or an insulating housing for receiving a mating plug.

[0003] Also, such angled plug connectors use a shielding (i.e., a shield plate) to shield electromagnetic interference from signal contacts and to discharge interference currents or return currents, and the shielding is connected to both the mating plug and the printed circuit board. Most of the shield plate is arranged outside the insulating body or housing. However, the attachment and manufacture of the shield plate on or in the insulating housing increases the complexity of the manufacturing process and the assembly process.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Therefore, an object of the present invention is to provide an angled plug connector with an electrical shielding, as well as a simple and effective production method for manufacturing and assembling the shielding or the plug connector.

Means for Solving the Problems

[0005] This object is achieved by providing a plug connector according to claim 1 and a production method for a plug connector according to claim 8. Advantageous embodiments are specified by the dependent claims.

[0006] The angled plug connector according to the invention includes an insulating housing, an angled contact element for establishing a connection between a corresponding plug and a printed circuit board, and a first shielding and a second shielding forming a shielded channel. The first shielding is formed as an angled metal sheet, in one piece or as a one-piece, and is inserted into the plug-in region of the plug surface of the insulating housing from the side facing away from the plug side. When the insulating housing is designed like a bushing, the interior of the socket forms the plug surface. In particular, the section of the shielding can be inserted into the corresponding opening and / or receptacle of the housing during assembly.

[0007] In the present application, terms such as "sheet", for example, "metal sheet", "angled sheet", "shielding sheet", etc. are used. In the present application, the term "sheet" includes the term "plate", for example, "shielding sheet" includes "shield plate" or "shielding plate". The term "sheet" means a thin plate that can be stamped to form cutouts, gaps, etc., and a part of the sheet can be bent to form an angle.

[0008] The two shieldings can be composed of two or more shielding sheets that shield, for example, the electromagnetic interference field from the signal contacts and release the interference current and the return current. For such reasons, the shielding sheets are in contact with both the mating plug and the connection to the printed circuit board. The shielding sheets are present, among other things, in the plug-in area within the plug surface of the insulating housing. Thus, contact with the mating plug is possible and the shielding sheets are protected against external influences. A flat and planar outer surface can be provided on the outside of the insulating housing. Since the outer surface enables adsorption by a handling machine during the processing, it facilitates handling the plug connector in the assembly process and the packaging process.

[0009] The insulating housing is fitted from the side facing away from the plug side (of the mating plug). The shielding sheet can already be fully bent when installed for connection to the printed circuit board, thereby simplifying the assembly. The shielding sheet is installed by introducing, sliding, inserting, and / or guiding one or more shieldings inside the insulating housing.

[0010] The first shielding and / or the second shielding are, among other things, arranged in the plug-in area of the plug surface such that the mating plug provided with external contacts can contact the shielding from the inside.

[0011] Among other things, the second shielding is formed as one angled metal sheet or as a plurality of angled metal sheets and is inserted from the side facing away from the plug side within the insulating housing.

[0012] The first shielding and / or the second shielding are preferably formed as stamped or punched metal sheets.

[0013] The first shielding and / or the second shielding can have at least one fastening element stamped into or out of the metal sheet, and / or can have a fastening section for fastening the shielding to the insulating body part (i.e., the insulating housing) by introducing the shielding into corresponding recesses formed in the insulating body part. In particular, the fastening element and / or section can be pressed or overpressed into recesses provided on the insulating body part so that a frictional connection is produced.

[0014] The first shielding and / or the second shielding can have at least one spring tongue, and at least one spring tongue is stamped into or out of the metal sheet in order to contact the contact of a corresponding plug in the plug-in area of the plug surface of the insulating housing.

[0015] In particular, the second shielding is formed of one or more parts in the form of a plurality of segments that will be arranged adjacent to each other. Also, the first and / or the second shielding can be a bent metal sheet arranged to produce a bent shielded channel (i.e., a channel having an upper shielding and a lower shielding). Thus, only a few individual parts are required and the production process and the assembly process are simplified.

[0016] When there are a large number of poles between the bottom and the upper wall of the plug surface, the insulating housing or the insulating body part can have a connecting element for stabilization, for example, a connecting web. The shielding sheet can still be used by being inserted into the slot from the front at the location of the connecting element, and the connecting element is designed to extend through the slot in the assembled state. When the second shielding is segmented, the connecting element can be arranged between two adjacent segments.

[0017] The method according to the invention for producing an angled plug connector, in particular a plug connector as described above, a) punching out the shapes of the first shielding and the second shielding from a metal sheet; b) bending the stamped metal sheet of the first shielding and / or the second shielding to produce an angled first and / or second shielding; c) sliding or inserting at least a part of the shielding into the interior of the insulating body part from the side facing away from the plug side; and includes.

[0018] The first shielding is preferably one-piece as described above. Also, the second shielding can be one-piece or composed of a plurality of segments, and the plurality of segments are stamped separately and arranged adjacent to each other in the insulating body part.

[0019] The metal sheet is preferably uncoated. The coating process step is saved in this variant. Nevertheless, the material has resistance due to its properties.

[0020] In the first shielding and / or the second shielding, a fastening section for fastening to the insulating body part can be created by punching the metal sheet or by stamping / cutting into the metal sheet.

[0021] In the first shielding and / or the second shielding, a contact tongue for establishing contact with the contacts of the corresponding plug can be created by punching the metal sheet or by punching / cutting into the metal sheet.

[0022] The shielding can be positioned and fixed in the plug-in area by a simple crimped surface. The production of the crimped surface is a simple stamping process. The shielding is inserted and fastened in one step during installation, and the process is simple and effective. Alternatively or additionally, fastening tabs can be provided in the connection area, and the fastening tabs are aligned in the direction of placement or insertion of the shielding into the insulating housing. The fastening tabs can contribute to a firm and effective positioning and fastening in the connection area of the insulating housing.

[0023] As a result, the present invention relates to a plug connector that can be easily produced and assembled using an angled shielding channel or shielding cage composed of two or more shieldings, the two or more shieldings being stamped from a metal sheet and optionally cut, bent, and inserted into the insulating housing from the rear (by a uniform insertion direction). At least a first shielding section of the bent shielding sheet is inserted into the plug-in area of the plug face of the insulating housing, such that a corresponding mating plug inserted into the plug face can contact the shielding sheet from the inside. Also, the fastening section and the contact tongue can be easily created by stamping. For example, the upper shielding sheet and / or the lower shielding sheet can be fixed by protruding a crimped fastening section forward, and the fastening section is pushed or pressed into a provided gap or recess of the insulating housing. This structure of the fastening section or the gap can be repeated along the width.

[0024] In the context of the present application, all of the features described or to be further described should be combinable among all possible variations insofar as they are technically feasible.

[0025] Further advantages, features, and application options of the present invention will become apparent from the following description, which is presented with reference to the drawings for embodiments of the present invention. It should be noted that the embodiments described below merely illustrate some embodiments of the present invention and should not be construed as limiting the scope of the present invention.

Mode for Carrying Out the Invention

[0027] The angled plug connector 1 according to the present invention is shown in FIG. 1. This is designed as a kind of adapter bushing / receiving housing for a corresponding plug (not shown).

[0028] The plug connector 1 has an insulating housing 2 made of plastic. The insulating housing includes an upper wall portion 20, a lower wall portion 21, and side wall portions 22a, 22b. The upper wall portion 20 has a flat and planar outer side. This enables suction for handling the housing 2 during assembly. The wall portions define the boundaries of the receiving spaces for the corresponding plugs. In addition, the insulating housing 2 has a block 23 that determines the plug surface. The block 23 separates or insulates the received contacts 3 of the plug connector 1 therein and the plug-in contacts of the corresponding plug therein. In this embodiment, the contact element 3 or contact 30 (see FIG. 3) of the plug connector 1 is formed as a contact blade or contact spring, or a combination of the two. In addition, the plug connector 1 has a multi-part shielding composed of a first (upper) shielding sheet 4 and a second (lower) shielding 5. The shielding sheet 4 is formed as a one-piece or single part. The lower shielding 5 can be a one-piece. However, it may preferably be composed of two or more segments or shielding sheets arranged adjacent to each other as shown below in FIG. 2. The shieldings 4 and 5 are at least partially disposed inside the insulating housing 2. The first shielding sheet 4 extends along the inside of the upper wall portion 20, and the second shielding 5 extends along the inside of the lower wall portion 21.

[0029] 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 is composed of two stamped and bent components or metal sheets 5a and 5b arranged adjacent to each other. The shieldings 4 and 5 can be easily stamped, cut, and then bent from a metal sheet.

[0030] The first (upper) shielding sheet 4 has a first shielding section 40 and a second shielding section 41 angled at a right angle thereto. The first shielding section 40 is inserted in the insertion direction E into a corresponding receptacle 24 in the insulating housing 2 during assembly. The second shielding section 41 forms the rear side of the angled plug connector 1. Fastening tabs 42a, 42b extend forward on both sides of the second section 41. The fixing of the first shielding sheet 4 occurs by inserting the tabs 42a, 42b into corresponding recesses 25a and 25b in the insulating body 2. The first shielding sheet 4 has contact feet 43, which create an electrical connection to the ground contact of the printed circuit board 6 as shown in FIG. 3. Spring tongues 400 are created by punching and crimping a metal sheet, and the spring tongues 400 are formed in the first shielding and create a firm electrical contact with the corresponding contacts of the corresponding plug. If the insulating body 2 has vertical strengthening walls (not shown) to stabilize the housing 2, the shielding sheet 4 can be guided by slots 401 formed in the first shielding section 40.

[0031] The second (lower) shielding sheets 5a and 5b are constructed in the same manner as 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 (shown for example only in the lower shielding sheet 5a). The second shielding section 51 is substantially shorter than the second shielding section 41 of the first shielding sheet 4 for geometric reasons. Its height or length depends on geometric conditions, i.e., substantially on the distance of the first shielding section 50 from the contacts of the printed circuit board. If necessary for geometric reasons, the second shielding section 51 can be non-existent or can have a height of zero. The contact 53 then extends directly from the first shielding section 50 towards the printed circuit board at a predetermined angle. The first shielding section 50 is inserted in the insertion direction E into the corresponding receptacle 26 in the insulating housing 2 during assembly. One of the fastening sections 52 is represented in Figure 4. The fastening section 52 is formed as a stamped and crimped tongue. During assembly, they are inserted and fixed into the corresponding recesses 27 of the insulating housing 2. Thus, the second shielding 5 is fastened to the insulating housing 2. Its fixation occurs, inter alia, by overpressing, i.e., the recess 27 above the insulating housing is slightly narrower than the fastening section. As a result, a frictional connection is achieved.

[0032] The spring tongue 500 is created by punching and crimping a metal sheet. The spring tongue 500 is formed within the second shielding and creates a firm electrical contact with the corresponding contact of the corresponding plug. Its structure can be repeated in the width direction along the front edge of the second shielding 5. The second shielding 5 has contact feet 53 in order to establish an electrical connection to the ground contact of the printed circuit board 6, as shown in FIG. 3. If the insulating body 2 has vertical strengthening walls (not shown) to stabilize the housing 2, this can be guided by slots 501 formed in the first shielding section 50.

[0033] Insertion during assembly is performed in a uniform insertion direction E from the rear side or connection side of the plug connector 1 (the rear side is the side opposite to the plug face) with respect to all shielding sheets 4, 5a, and 5b. The assembled plug connector 1 is shown in FIG. 3 (parts of the insulating body are omitted in the explanatory drawing). In particular, the design and arrangement of the contact elements 3 are shown. These have contacts 30, which are arranged in the plug face side by side adjacent to each other or vertically. In addition, the contact element 3 has a bent contact section 31, and the end of the contact section 31 is in contact with the corresponding contact 60 of the printed circuit board 6. Also, the contacts 31, 60 are arranged adjacent to each other in rows and columns. During assembly, the second shielding sheets 5a, 5b, the contact 3, and the first shielding sheet 4 are inserted into the insulating housing 2 in order from the rear side.

[0034] Figures 4 and 5 show, among other things, the details of the second shielding 5, which includes a fastening section 52 disposed between contact tongues 500. The fastening section 52 protrudes into the recess 27 of the housing 2, but the contact tongues 500 are bent upward to establish good contact with the corresponding mating contacts of the corresponding plug. It is clear from FIG. 5 how the contact tongues 500 are created by punching and bending a metal sheet.

[0035] The fastening and fixing of the upper shielding sheet 4 can be performed in the same manner. Therefore, the structure of the front edge of the upper shielding sheet 4 substantially corresponds to the structure of the front edge of the lower shielding 5.

[0036] Since the parts of the shieldings 4, 5 are merely stamped, bent, and inserted into the insulating housing 2, both the manufacturing and assembly of the plug connector 1 are simple.
