Description

Controller with pull-out structure

technical field

The invention relates to a controller, in particular to a controller with an anti-pulling structure.

Background technique

The controller must be connected with a power cord or a connecting wire and other connectors, so that the power can be supplied by the power cord to start, and the data or signals can be transmitted through the connecting wire to carry out operations. The loss of data, in severe cases, will also cause the stop of the entire system or machine, and the loss is by no means ordinary.

Therefore, there are currently several anti-tear structures on the market to prevent the connector from falling off the controller socket. Two examples are given here, as shown in Figure 1 and Figure 2. The anti-tear structure in Figure 1 has an upper Block 10 and the following block 20, one end of the upper block 10 is integrated with one end of the lower block 20, and the other end has a matching groove 11 and a hook 21 respectively. The upper block 10 There is also a blocking piece 12 extending toward the lower blocking block 20 on one side;

When the joint A with the convex wall A1 on the peripheral edge is inserted into the socket of the controller, the pull-out prevention structure is locked and positioned by the slot 11 of the upper block 10 matching the hook 21 of the lower block 20 On the controller, the block 12 of the upper block 10 cooperates with the convex wall A1 of the joint A to restrict the joint A, so that the joint A cannot be pulled out from the socket of the controller;

However, the pull-out prevention structure is positioned by the draw-in groove 11 of the upper block 10 in conjunction with the hook 21 of the lower block 20, which is not so easy and convenient to disassemble, and it is easy to cause the lower block after multiple disassembly. The deformation of the stopper 20 will seriously cause the fracture of the lower stopper 20, so this structure is not ideal, and there is room for improvement.

Another anti-extraction structure is shown in Figure 2, which is to form two clamping posts C1 on the joint C in the direction of inserting into the socket B1 of the controller B, and each of the two clamping posts C1 has a hook C2, the socket B1 cooperates with the hooks C2 of the two clamps C1 to form two through holes B2, when the joint C is inserted in the socket B1, the joint C can connect the two clamps C1 The hooks C2 are respectively engaged and positioned in the two through holes B2 of the socket B1, so that the connector C cannot be pulled out from the socket B1 of the controller B;

However, this kind of pull-out prevention structure must use a specific connector C and controller B. General connectors cannot be used universally. Moreover, the positioning of the hook C2 on the two clamping columns C1 of the connector C must be released first before the connector can be removed. It is quite troublesome to pull out the joint C, and the jack B1 of the controller B is provided with the two through holes B2 for the positioning of the hooks C2 of the two clamping posts C1, and the jack B1 is bound to protrude outward As for the controller B, it takes up space and is not very attractive in appearance, and compared with the previous anti-tear structure, it seems to be full of problems.

It can be seen that although the anti-drawing structure is quite important, there have been many shortcomings that have not been resolved in the past. If the aforementioned shortcomings can be improved, there must be considerable economic benefits.
