Description

Halterunq for mounting an optical module, in particular a socket part for an optical connector on a circuit board

The invention relates to a fixture for mounting an optical module, in particular a socket part for an optical connector on a circuit board according to the preamble of claim 1. Such holders are required for example in optical sockets to hold a plurality of jack parts in the correct relative position. However, other optical modules such as optical transmitter / receiver units, optical switches, etc. must be fixed on purpose assige way on boards, in particular printed circuit boards.

There have been known genus ässig comparable mounts of metal, in which through the retaining feet inserted through slots in the board and are bent on the back. However, metal sleeves are expensive to produce and are not suitable for all applications. Also, the fixing by bending and / or soldering the feet requires a high degree of care. It is therefore an object of the invention to provide a holder of the type mentioned which may be manufactured inexpensively in large series and can be attached without great expense to a circuit board. This object according to the invention is achieved with a holder having the features in claim. 1

The one-piece production of plastic material provides lightweight, electrically non-conductive sleeves that can be produced inexpensively by injection molding in large series. To better distinguish between different types of sleeve, the sleeve can also easily ben colourise. The formed as webs holding feet with a locking rib permit simple snap the sleeve onto a circuit board. Additional measures for fastening are not required, and the connection between the sleeve and the board is always of the same quality. The arranged between the supporting feet relief slot increases the elasticity of the mounting wall in the critical area, so that the sleeve is not damaged on the board during snapping.

The relief slot preferably extends approximately over the same length as the supporting feet. It runs parallel to the holding legs, but it could extend to the retaining feet also curved at an angle or. Preferably, associated with each mounting base, a separate relief slot, in particular when the holding feet apart are relatively wide.

In a preferred embodiment, two retaining feet on the mounting wall being arranged and their locking ribs are arranged facing each other on the side of the webs. The webs are thereby spread on the board during snapping apart and then spring back once the locking ribs have reached the back wall of the board or a corresponding recess. The snap action can thereby be further improved if the webs taper from the neck to the mounting wall to the free end in the cross-section is preferably wedge-shaped.

A hinge effect at the holding legs can also be achieved if one each groove is disposed in the mounting wall with each mounting base along the inside of the neck. This groove facilitates the disassembly of the retaining springs feet and it also prevents cracks in the critical neck area, because the forces are better introduced into the mounting wall during spreading of the holding feet. Preferably, the support feet are also so offset relative to the parallel side walls of the sleeve arranged such that the inner distance between the side walls corresponds approximately to the outer distance between the supporting feet. For stability reasons, the parallel side walls of the sleeve over the entire length of the support feet are designed reinforced.

Further advantages and individual features of the invention will become apparent from the following description of an embodiment and from the drawings. Show it:

Figure 8 is a cross-section through the holding device according to Figure 7 with an inserted male part. Reference to Figures 1 to 5 of the structural design of a holding device is first described in detail. This consists of a hollow box-shaped sleeve 1 made from a suitable plastic material, for example, in The

Rectangular cross-section sleeve has a mounting wall 2, parallel side walls 3, 3 'and a top wall. 4

On the outside of the mounting wall 2, the holding legs are arranged laterally 5 and 5 '. These consist essentially of a web 6, laterally a locking rib 7 is disposed at the. The locking ribs on the two holding legs are facing each other. Snapping on a circuit board is facilitated by a chamfer 27th

Each web 6 is tapered in cross-section slightly from the projection 9 on the mounting wall 2 to the free end 10. This taper is achieved by a wedge angle α of, for example 2.5 °.

The ridges 6 of the holding legs extending over only part of the total length of the sleeve 1. About the other hand, the entire length extends a respective groove 11, which is arranged directly next to each land 6 in the area of ​​the projection 9 on the inside. The ribs 6 are also arranged so that their outer distance Aa corresponds approximately to the internal spacing Ai between the side walls 3, 3 '. The webs are thus can be seen, on a plane between a side wall 3 or 3 'and a groove. 11

Between the two retaining feet 5, 5 in the mounting wall 2 'two relief slots 8, 8' are arranged. The discharge slots extend approximately over the length of the webs. 6

The two side walls 3 and 3 'are provided on the outside with a reinforcement 12 which also extends approximately over the length of the webs. 6 Respectively in the region of the mounting wall 2 and the top wall 4, the side walls are provided 3 and 3 'with a taper fourteenth For a better guidance of the to be inserted into the sleeve bushing parts is achieved. To the mounting wall 2 supports 13 are provided on the inside, which extend in the longitudinal direction of the sleeve. The socket to be inserted parts are on these requirements.

Figures 6 and 7 show the sleeve 1 described above, which may have two bushing parts 15, 15 take up '. This connector parts have a substantially prismatic outer shape and their mutually facing inner sides 18 lie flat against one another. The female parts have insertion portions 16, 16 ', which project beyond the ends of the sleeve 1 at both ends. the insertion portions support ribs 19 are arranged in the region of the mutually remote outer sides 17 of the socket parts. These support ribs can be supported at the outer edge 20 of the sleeve 1 and they ensure in this manner the bushing parts in the sleeve. Upon insertion of the sleeve parts into the sleeve, the two side walls 3, 3 'of the sleeve are Evidently slightly expanded by the support ribs.

can on the protruding sections of the sleeve 1 Introduction end frame 21, be snapped 21 '. the frames are equipped for this purpose via a respective bar 22 at the upper frame limb and cam 23 on the lower frame limb. A ledge 22 engages the transverse grooves 25 on the female parts and the cams 23 engage in recesses 26 (Figure 8). The lateral recesses 24 on each frame can accommodate a form-fitting the support ribs 19th The end frame on the one hand form a neat finish of the sleeve 1 and they serve the same time of coding by using only connector parts to each matching frame can be inserted into the module. Figure 7 shows a finished composite module on an indicated circuit board 28. As shown in particular in Figure 8 can be seen, having the circuit board 28 for each mounting base 5 is a slot 29 whose width is dimensioned so that a detent rib 7 can just be pushed through. The locking rib engages in the end position behind the circuit board 28 so that a distance of the sleeve is only possible with a certain force.

Of Figure 8 further details of an already known bushing portion 15 and an associated plug part 33 are visible. The female part has on each plug side a catch 30 that can latch on the plug part of a locking bar 35 once the plug has reached its final position. In this end position, the connector pin 34 penetrates into the actual sleeve 32, which is mounted in the socket part. For disconnecting the plug uss a release lever 36 are operated, wobei- the pawl 30 is lifted over the locking bar 35th In general, it is the male part of a so-called duplex connector, in which two identical connector housing with limited game are held together so that they can penetrate into the two parallel connector parts 15, 15 'simultaneously. The bushing parts are provided with aperture 31 which cover the respective exposed opening a socket 32 ​​at ausgestecktem plug part.
