Description

The invention relates to a female header or a 90 ° pin header or a spring and knife header for one electrical connectors, each consisting of a insulating body front part provided with several contact elements and a pluggable insulated back part, with at least the front part of the socket strip consists of at least two modules and single, double, four, eight, etc. modules form a module row.

A plug connector is known from EP 0 393 251 A1 known as a female header or a Pin header formed resin can. The socket or. Pin header consists of one with several Insulator body provided with contact elements - front part and a plug-in insulated back part. The front part is made from at least two modules and simple, double, fourfold, eightfold etc. modules form a straight line or odd front row of modules. The back consists of at least two modules and simple, form double, quadruple, eightfold etc. modules a recent module row. The lengths of the front and the upstream module rows are in the longitudinal direction measured identical.

The front and Back modules are made using additional connecting means, the as a circuit board on which the Front part modules are attached, and as openings and fasteners are formed by the the back module attached to the circuit board are connected. The from the Modular socket or pin header can without the additional lanyard not be handled as a part.

Socket strips have become known from EP 0 408 212 A1. Furthermore, the mentioned module series, in which the the next largest module is twice the length and number of contact elements compared to the next smaller one Module, known or standardized on its own.

With the socket connector mentioned, the modules are on one perforated plate attached, the perforation with the geometric arrangement of the contact elements of the modules matches. All modules are then L-shaped Rail and locking clips held together, the rail itself on the plate is held. This creates a relatively stable one Receptacle.

The disadvantage of this socket strip is that you can in Depends on the total length of all modules of the respective Connector the L-shaped rail of a meter long Cut off pieces or make them to this length from the beginning got to. In view of the large number of customer requests, this leads to this resulting, often small series of different lengths Connectors at relatively high manufacturing costs. At most if a particularly large number of whole certain connector to be manufactured, the falls separate manufacture of the L-shaped rail just for this Series doesn't matter so much. But this is rather rare.

In another known connector (EP 0 422 785 A2) are all insulating body front parts or modules of the same length - of course all other geometrical are also correct Dimensions and number of contact elements of the modules match - however, the back of the insulating body is made of very short ones Elements built, with an insulating body front part six Insulator backs are assigned. With a fairly long one Female header with, for example, several hundred Contact elements are therefore quite a large number of Insulator back parts required. This also leads at fairly high manufacturing costs. With a bulk item, um which it is with such socket headers and pin headers acts, lead to the smallest cost savings on one single socket strip or pin header over the series or seen a daily production, at a respectable Total amount.

The prior art on which the invention is based exists in individual modules with respectively assigned or molded back, but different sizes can have, e.g. a length of 12 for a 24-pin module mm, with a 48-pin module 24 mm, with a 96-pin module 48 mm, with a 192-pole module 96 mm etc. In addition, they will individually mounted on printed circuit boards. The user must therefore e.g. order four different parts, four different ones Receive parts, check them, keep them in stock and to process. The work steps are that he has to reach into a magazine four times, grab four times, four times to put the parts on the circuit board, four times must join the parts and must press four times.

As a result, there is the task of a female header or 90 ° pin header so that with a relatively small number of parts, within the scope of the gradation the modules of the module row of the front part, almost any long socket strips or 90 ° pin strips, regardless of the Series number or the scope of the order, with the lowest costs Have it manufactured so that only a part can be handled got to.

This object is achieved with a socket strip or 90 ° pin header of the type mentioned by the in claim 1 or Features specified in claim 2 solved.

As a rule, one gets a female connector or 90 ° pin header, the insulating body front part of one very specific number of modules of a specific size is an equal number of modules of the same size for the Use the back of the insulating body.

Any number of contact elements are conceivable, but that simplest module preferably has 24 contact elements in several superimposed rows, e.g. four rows of six arranged one above the other. The double module therefore has 48 or more Contact elements etc. The largest module currently in use The insulating body front part is an eight-way module with 8 by 24 or 96 or more contact elements. So if one Female header e.g. 200 contacts should have, so can the insulating body front part easily by using build an eight-fold module and a single module. Accordingly, it is best to use it for the back of the insulating body is an eight-way module and a single module. Some of the contacts e.g. of the simple module available as reserve contacts.

It is easy to see that the simple module is not necessarily 24 contacts or 30 contacts for 5 rows or correspondingly more contacts with more rows or Must have contact elements, but that it is also less can be, which is the case, for example, when a Combination of different types of contact elements is required. The same applies to the other modules in the module series analogous.

With the system described, the following connector strips can be created, for example:
Female Solder Signal, Female Solder Power, Female Solder Signal + Power combined and other special modules or Female Press-fit Signal, Female Press-fit Power, Female Press-fit Signal + Power combined and other special modules. With regard to the 90 ° pin header, for example, the following options are available: Male 90 ° signal, male 90 ° power, male 90 ° signal + power combined and other special modules.

From, for example, only seven individual parts, namely four Front parts of a module row and three back parts of one identical module row, with the longest module is waived, if one of the mentioned 24-bit grid runs out, socket strips or 90 ° pin strips with 24 to 528 contacts, using e.g. two to 22 or more modules. So that can meet practically every customer request, including at Small series, without additional costs compared to the Large series are created.

A further development of the invention provides that one two modules of different lengths of the insulating body front part the modules of the back of the insulator also are of different lengths, the longer module of the Insulator back the joint of the modules of the Insulator body overlaps or vice versa. One has So here two modules of the same length, but you don't set that long back part directly to the long front part, but to the short front part so that it is the joint between the overlaps the other two modules, resulting in a good one Stability of the entire socket strip or pin strip leads. The same applies to a female header or Pin header, which is made up of more than two modules. In in any case, the joint between adjacent Modules of the front part of a module of the back part be attacked or vice versa.

The socket strip 1 of Figure 2 consists essentially of the insulating body front part 2 and the insulating body rear part 3, both in a known and therefore not shown in detail and described described are pluggable together. The direction of insertion is symbolized by arrows 4 and 5. The insulating body front part 2 takes the in a known manner Contact elements 6, their shape, size, in groups Summary and placement in the insulating body as well is known prior art, but the known Details differ in details. The Socket strip 1 is, for example, with a printed circuit board 7 mechanically and electrically connected, also in this respect known prior art can find application. there then pass through the free ends 8 of the contact elements 6 Corresponding groups of holes in the circuit board 7. The electrical Connection is made by soldering or solderless Joining techniques, e.g. Press in, the mechanical Connection, for example, via the melting of the free Ends of plastic pins that go over the bottom of the PCB 7 protrude, or positive Plastic pins or solderable connections.

The insulating body front part 2 of the socket strip 1 consists of Modules that differ in length 9 from each other differ. In the explosive representation of the figure 1 shows the smallest module at the bottom right. It owns on its insertion side e.g. four rows of six each Insertion openings 10. The next largest module has one double length and number of contacts. Other modules can have four and eight times the length. Larger, so each modules twice as long are usually not included Use. Except for the length, all other dimensions are the modules of different lengths are the same.

The socket strip 1 of Figures 1 and 2 consists of a Single module 11 and a quadruple module 12. The total length therefore corresponds to five times the length of a single module 11. According to the insulating body back part 3 is made of Modules constructed, the length 13 of the single module 14th the length 9 of the single module 11 of the insulating body front part 2 corresponds. The same applies to that Double, quadruple module etc.

In the same way as the insulating body front part 2 of the Female header 1 consisting of a single module 11 and a quadruple module 12, the insulating body back part 3 is made of one Single module 14 and a quadruple module 15 constructed. there However, the quadruple module 12 is not behind the another quadruple module 15 mounted, rather that covers longer module, in this case the quadruple module 15, which is flush with the outside of the single module 11 of the outside Completes front part 2, the joint 16 of the insulating body front part 2. The is accordingly Joint 17 of the two modules 14, 15 of the insulating body rear part 3 on the back of the quadruple module 12 of the front part 2.

It is easy to see that when using the above Module series with the staggering 1, 2, 4, 8 etc. for the Front part 2 and the rear part 3 socket strips almost can create any length due to the offset the joints 16 and 17 good stability of the Ensure socket strip. For a long female header of course, the largest possible number of eightfold - or at least use quadruple modules, and only if their Plug-in openings or similar connection points required number does not result, in addition a single or add a double module. It is recommended for that Front part 2 and back part 3 the same number of modules to be provided, in each case with the same length dimensions. However, according to the above statements in Deviations if necessary or emergency.

The advantages of building a female header in the above described way and of course the 90 ° pin header or knife bar of Figures 3 and 4 exist above all, in being a better one Machine utilization gets and with spraying machines none Mold remodeling is necessary. The conversion effort for Plastic injection mold and assembly, which so far was inevitable, is largely eliminated. This will make the Optimized resource utilization, resulting in a Reduce overhead costs. You also get a high one Flexibility that enables the shortest delivery times. this applies also for prototypes and small series. The logistics effort will minimized and due to the limited length of the individual modules inexpensive material can be used for this.

With new pole numbers, no investments are required the latter also applies to mixed pole pictures as well as for Assembly machines for higher numbers of poles. With a mixed The single module 11 has no 24 contact elements, but a smaller number as well as additional ones, in particular larger contact elements for the power connection, while the "Normal" contact elements are used for signal connection.

As a result, the delivery times for such socket strips, but also pin headers with new or different pin patterns be kept short. Because less changeover is required, throughput times can also be reduced.

A 90 ° knife or pin strip 21 is shown in FIGS. 3 and 4 shown, and in analogy to Figures 1 and 2 as exploded drawing and according to Figure 4 as Assembly drawing. This pin header 21 also consists of a Insulating body front part 18 and an insulating body rear part 3. The choice of the same reference number shows that the insulating body back 3 of this pin header 21 that of Socket strip 1 corresponds to Figure 2.

The formation of the insulating body front part 18 is with regard to its shape, dimensions and Contact arrangement and contact training as such already known. The free ends 8 of its contact elements 6 enforce here, for example, a circuit board 7 the electrical and mechanical in the manner described are connected.

The insertion openings 10 of the socket strip 1 correspond to the pin-like ends 19 of the contact elements 6 of the 90 ° knife bar or pin header 21 in terms of number and Arrangement so that the socket strip 1 of Figures 1 and 2 in the direction of arrow 20 on the pin header 21 to thereby the electrical connection between the printed circuit board 7 the socket strip 1 and the circuit board 7 of the 90 ° pin strip 21 manufacture.

In the embodiment of Figures 3 and 4 is both Insulator front part 18 and the insulator rear part 3 of the 90 ° pin header 21 made up of individual modules 11, 12, 14, 15. In this respect, there is agreement with the training of Female connector 1 and it is therefore necessary in this regard no further explanations. The explanations apply to the socket strip 1 analogously for the 90 ° pin or - Knife rail 21.
