Locking device for electrical connectors

The priority of filing in the United States of America on February 3, 1964 34-1 »857 is used.

The invention relates to an electrical connector, in particular a quick release type of electrical connector, with a male member releasably engaged with a female member and connecting one or more circuits.

There are locking and unlocking devices in connectors known, in which mechanical parts snap in the locked state behind appropriately designed links. It is also known to cancel this lock again. On the mechanical Parts act in these known arrangements springs that ever a certain spring stiffness according to the required locking force or have spring force Part, in particular the spring, has a certain natural oscillation, which, stimulated by the shock, resonate with it and can lead to an unwanted release of the lock.

The invention h.at the task of a locking device, Especially for connectors, to create that even when exposed strong ürschütteruiigen (vibration) the connecting Keeps ropes locked securely. According to the invention this is

achieved in that a lockable device is provided that penetrates the connector in its center and of several cooperating with each other There are parts that can be operated one after the other as a function of one another. The individual on the mechanical Springs acting on parts have different spring stiffness and respond to different resonance frequencies.

The invention has the particular advantage that the "locking cannot be influenced by vibration or shock.

back to the above forward movement of the remaining parts, bis-the lug 184 at the front ends of the fingers 174 of the Attack tube 172, which at this point in the front end 164 of the tube 152 are compressed ",

If the main parts of the unlocking device are moved forwards by turning the handwheel 74, the plunger 168 of the plug 166 rests against the union nut 84, so that further forward movement of the tube 162 is prevented the forward movement of the spool 90 of the tube 112 and locking bolt 138 continues, v / obei also the tube 172 is moved forward by the bolt 140, so that the spring washers 180 are compressed.

is set, in the position corresponding to FIG. 5. The rear part 94 together with the coil housing 92 and the tube 112 pulled backwards, at the same time the locking bolt 138 is moved backwards because its front end from the heads 116 of the tube 112 is held. The tube 162 and thus the Unlocking device 160 is held in place by spring 88, so that the locking bolt through the unlocking device is pushed through and the collar 154 of the bolt 140 lifts from the plan 168 of the plug 166. Now it is Unlocking device ready for insertion into the Sp.erring 28 of the socket link.

In Figo 6 the interaction of plug and socket is shown. The plug is pushed forward. The tube 126, which keeps the ends of the fingers pressed together, pushes against the edge of the locking ring 28 and remains there while the heads 116 continue in penetrate the locking ring and spread open behind the constriction 122 ο.!

relative to the pipe 112 and a favorable blocking of the heads 116 takes place, as Pig _o 7 showed

When the backward movement of the tube 112 proceeds in this way, it places the shoulder 148 against the collar 14-6 of the locking bolt and takes it with it. This relative movement between Eohr 112 and locking bolt is shown in S ¹ Ig. indicated by the gap "D" between shoulder 148 and collar 146 «It has _{closed in]? ig 0} 7., *

Turning the handwheel clockwise between Figo 6 and 7, by pulling back the Eohres 112 in the connector housing, the connector and socket member pulled together "

Between J ¹ Ig ₀ 7 and 8 the handwheel was turned further clockwise, thereby the unlocking device 26 was moved overall backwards with the exception of housing 66, handwheel 74, adapter 72 and union nut 84o During this movement, the spring 88 is compressed relatively strongly. At this point in time, the outer insulating plate 50 of the socket member has been pulled against the outer insulating plate 38 of the plug member, and the sheet 58 is moved at the rear against the spring force of the leather .45 woydejs / "oils loir & act pins 14 are in engagement with -the

'corresponding contact "bushes 2O ₀ The handwheel is turned" until the male and female members are completely in engagement with one another, as in Pig. 2 and 8 is shown.

Now a further movement of the unlocking device would still be possible, as the gap ¹¹ B ″ between the front end of the adapter 72 and the rear shoulder 194 of the bobbin case showed

Further rotation of the handwheel is then only cause tension in the bolt parts which are opposite to the cohesion of plug and socket member _o

In the fully locked position, as in KLg. 2 and 8 shown,., the locking bolt 138 is caused by the forces of the leathers 150 and 152, which have different resonance frequencies, are held in place so that whenever a of the two leathers becomes ineffective in their resonance frequency due to vibration, the other remains effective in order to keep the locking bolt in its!

The mass of the unlocking device 160 is prevented from acting on the locking bolt through vibration or impact, because the entire unlocking device is secured by the strongly compressed leather 88 against the now fixed rear part 94 of the sink housing 88 becomes ineffective due to a critical resonance frequency, is this resonance frequency different from that of the two leathers 150 and 152, so that these two remain effective _? and their spring forces are sufficient to prevent any change in the mass of the locking bolt and the unlocking device

rearward movement is effectively prevented by pressure on tube 162, which in turn is prevented from rotating by spring 88 and, if necessary, even springs 150 and 152. The spring 188 absorbs most of the vibration or impact pulses which the armature forward want to move, since the anchor can move forward by an amount corresponding to the gap ¹¹ G "(Fig. 8). Gap" G- "is the normal distance between the paragraphs 190 and 192« For when there is a shock or shock are large that the relatively light armature 108 overcomes the distance "G-", which rarely occurs, the further forward movement is safely stopped by the strong counterforce of the spring 186, which holds the sleeve 182 in its locked position. The spring 186 is much stronger than the spring 188, and both have different resonance frequencies.

When the coil is now excited, the magnetic attraction drives the armature forward, sufficient to overcome the gap "O" and the force of the relatively weak spring 188. Ba the force of the magnetic attraction is inversely proportional to the square of the distance, the much stronger second fire 186 does not interfere with the closing of the gap ^'11 O "', as soon as the gap - ¹¹ G" is closed and the armature has taken the sleeve 182 with it If the coil slightly excited the successive and combined forces of the fecers 188 and 166, in order to enable the sleeve 182 to be advanced;
