Description

A kind of device with automatic detection cooperation compactedness function

Technical field:

The present invention relates to a kind of device that automatic detection coordinates compactedness function that has.

Background technology:

Along with the high speed development of infotech and the integrated level of information equipment system more and more higher, signal demand more and is more at a high speed crossed over plate level and is realized communication between system or between disparate modules.The HW High Way integrality that how to guarantee in high quality these straddle levels is a very important problem.It is interconnected that the HW High Way of these straddle levels realizes plate level by means of connector (connector) in most cases.The compactedness of connector combination is a very important factor that affects signal integrity.Must there be a margin tolerance in mechanism in the process of processing, the difference of each product as long as be exactly qualified product in this margin tolerance, and tolerance cumulative between a plurality of modules, can accumulate the deviation that enlarger coordinates, even contact is not upper to cause connector to coordinate undertighten, thus the signal integrity of the HW High Way that impact is passed through.On the other hand, in mechanism's process, precision is inadequate, and error or the defective deviation causing can be larger.Fig. 1 is that connector coordinates deviation schematic diagram.A module with connector male is inserted the backboard with female mouthful of connector, existence or processing error due to mechanism's tolerance, the one, can in x direction, produce the situation that connector male is not inserted into female mouthful of bottom of connector, the deviation of generation as shown in figure L2 and L3, the 2nd, can in y direction, produce deviation, cause the deviation shown in (L3-L2); The 3rd, also can in z direction, there is deviation.Particularly the length of connector (L1) is longer, and the mismatch error that connector produces is just larger, also just larger on the impact of high speed signal integrality.

The deviation coordinating for fear of connector, conventional way is that the cooperation that guide post (Guide Pin) guarantees connector is set on connector at present, guide post coordinates accurately and can guarantee to a large extent in the precision perpendicular in direction of insertion, it is the y direction shown in Fig. 1, but can not effectively guarantee the precision coordinating in the x direction shown in Fig. 1, in x direction, be easy to exist untight situation that coordinates.And most connectors only has a guide post, for long connector, upper perpendicular to direction of insertion (being the y direction shown in Fig. 1), at that end without guide post, still can there is larger error.The currently used method that guide post is set is that a physics guarantees means, for the open-and-shut judgement that whether closely can not provide of last cooperation on earth.

Summary of the invention:

The object of the invention provides a kind of device that automatic detection coordinates compactedness function that has, and this device can detect the compactedness of its cooperation automatically, only need just can judge whether this device coordinates closely by viewing lamp or signal level.

For achieving the above object, the present invention is by the following technical solutions: a kind of have a device that automatic detection coordinates compactedness function, comprise female mouthful of connector and connected connector male, female mouthful of port of described connector is provided with stitch I, described stitch I is connected with one end of signal wire I, the other end ground connection of described signal wire I, described connector male port is provided with stitch II, described stitch II and the corresponding setting of described stitch I, stitch II is connected with one end of signal wire II, the other end of described signal wire II successively with pilot lamp, resistance wire and power supply series connection, described stitch I contacts with stitch II, make described signal wire I and signal wire II form closed circuit, described signal wire II is connected with single-chip microcomputer, described single-chip microcomputer detects the level of described signal wire II.

Further, female mouthful of port of described connector is provided with stitch Ia from top to bottom successively, stitch Ib and stitch Ic, described stitch Ia and stitch Ic are chosen in the position of closing on female mouthful of port edge, both sides, described stitch Ib is chosen in the position in the middle of female mouthful, stitch Ia, stitch Ib and stitch Ic are respectively by described grounded signal-wires, described male port is provided with stitch IIa from top to bottom successively, stitch IIb and stitch IIc, described stitch IIa, stitch IIb and stitch IIc and described stitch Ia, stitch Ib and stitch Ic are corresponding to be arranged, described stitch IIa and stitch IIc are respectively by signal wire II and pilot lamp, the anode series connection of resistance wire and power supply, described stitch IIb connects with the negative electrode of power supply by signal wire II.

Further, between the signal wire II that the signal wire II that described stitch IIa connects is connected with described stitch IIc, be provided with single-chip microcomputer, described single-chip microcomputer detects the level of described signal wire II.

Further, described single-chip microcomputer is connected with terminal computer, and the level height of the signal wire II that described terminal computer detects according to single-chip microcomputer directly judges whether described plug-in unit contacts closely.

Further, described single-chip microcomputer is 51 unit sheets.

Owing to having adopted technique scheme, the beneficial effect that the present invention obtains is:

1, in female mouthful of connector and connector male, signal wire I and signal wire II are installed, when the female mouth of connector is connected with connector male, signal wire I contacts with signal wire II, forms closed circuit, the pilot lamp that is connected on signal wire II is brightened, thereby judgement connector connect closely.

2, signal wire is arranged on to the port of female mouth and male, close on the position at connector edge and the position of middle, the tight type be connected with male edge by detecting female mouthful, centre connecting, can react the compactedness that female mouth is connected with other parts of male more accurately.

3,, by connect single-chip microcomputer on signal wire II, by the level of microcomputer monitoring signal wire, be used for judging the compactedness that the female mouth of connector is connected with connector male.

4, the mode that adopts the female mouth of microcomputer monitoring to be connected compactedness with male is conducive to realize the robotization of monitoring, can directly offer intuitively user's connector and coordinate compactedness whether result.

5, signal wire I contacts by stitch with signal wire II, makes signal wire sensitiveer, has avoided being connected closely with connector male when female mouthful of connector, because of signal wire loose contact, causes erroneous judgement.
