In order to make those skilled in the art better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product, or apparatus that comprises a list of steps or elements is not limited to those listed but may alternatively include other steps or elements not listed or inherent to such process, method, product, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1 and 2, fig. 1 is a schematic diagram of a connection diagram of a robot teach pendant and a robot control cabinet in the prior art, and fig. 2 is a schematic diagram of a connection seat of a robot control cabinet and a safety IO module in the prior art. As shown in fig. 1, since the emergency stop button on the robot demonstrator is a pair of normally closed contacts, the connection plug on the robot demonstrator is connected with the robot control cabinet connection seat through a cable. As shown in fig. 2, the robot control cabinet connecting seat is connected with the safety IO module, so that the emergency stop button on the robot demonstrator can be connected with the safety IO module.

When an emergency occurs, an emergency stop button of the robot demonstrator is pressed, the two pairs of normally closed contacts are opened, and the safety IO module disconnects a power supply of the robot demonstrator after receiving a normally closed contact opening signal, so that the robot demonstrator can be stopped emergently. In this process, as shown in fig. 2, after the connection plug of the robot demonstrator is pulled out from the robot control cabinet panel connection base, the emergency stop button is triggered, so that the robot demonstrator needs to be always connected to the robot control cabinet in order to avoid the robot from emergency stop caused by the connection plug of the robot demonstrator being pulled out from the robot control cabinet panel connection base.

However, in some occasions, the robot demonstrator is not always connected to the robot control cabinet. For example, during a robot commissioning process (the robot teach pendant is mounted on the robot), the robot teach pendant needs to be removed from the robot control cabinet in order to commission the robot, and thus, a scram button on the robot teach pendant is triggered to cause the robot to scram. At present, the solution to this problem is usually to short-circuit the EMG1+ and EMG1-, EMG2+ and EMG 2-on the connection socket with jumper wires after the connection plug of the robot teach pendant is unplugged, as shown in fig. 2, and if the robot teach pendant is to be used for debugging, the jumper wires are removed and the robot teach pendant is plugged in, so that the technician finds that the operation steps are complicated and unreliable during the operation process, especially, safety accidents are easily caused.

To above-mentioned problem, this application aim at provides an install connector at robot demonstrator, and the connector can carry out the plug operation anytime and anywhere, and then the robot can not trigger the scram because of the plug, and the robot demonstrator breaks away from the disconnection back from the robot control cabinet simultaneously, and the robot demonstrator does not need the jumper short circuit in order to ensure that the robot demonstrator is not triggered the scram.

Referring to fig. 3, fig. 3 is a connecting socket of the present application, which includes at least a pair of conductive pin housings, an insulating lining seat, a conductive gasket, and an elastic member; the conductive pin housing includes an opening; one end of the elastic piece is fixed at the bottom end of the conductive pin shell, and the other end of the elastic piece is abutted against the insulating lining seat; the insulating lining seat is clamped at the opening part, the conductive gasket is installed on the insulating lining seat, and two ends of the conductive gasket extend to the wall of the inner side of the conductive pin shell.

In a preferred embodiment, the conductive pin housing is cylindrical.

Another embodiment of this application provides a connector, the connector includes connecting plug and this application embodiment the connecting seat 2, connecting plug with the connecting seat 2 pegs graft.

Preferably, the connection plug comprises conductive pins 11, and the conductive pins 11 are plugged with the conductive pin housing 21.

Preferably, the conductive pins 11 abut against the insulating lining seat 22.

Preferably, the conductive pins 11 are circular.

The following explains the principle of implementation and the effect of the present application.

When the connection plug is not connected to the connector holder 2 or the plug 1 is pulled out from the connector holder 2, the connector holder is in a state shown in fig. 3, the conductive pad 23 mounted on the insulating bush holder 22 is pressed by the elastic force of the elastic member 24, and the conductive pad 23 is pressed against the pair of conductive pin housings 21, so that the two conductive pin housings 21 of the pair of conductive pin housings 21 are shorted. As shown in fig. 3, the safety IO module has 4 interfaces, which are electrically connected to two pairs of two conductive pin housings 21, respectively, at this time, INPUT1+ and INPUT 1-interfaces of the safety IO module are conducted with the conductive pad 23 through the two left conductive pin housings 21, while INPUT2+ and INPUT 2-interfaces of the safety IO module are conducted with the conductive pad 23 through the two right conductive pin housings 21, so that the robot does not trigger an emergency stop without connecting a connection plug.

When the connecting plug is inserted into the connecting seat, the insulating lining seat 22 is stressed to move downwards, the conductive gasket 23 arranged on the insulating lining seat 22 can be separated from the conductive pin shell 21, at this time, a pair of pins on the left side of the connecting seat are conducted without short circuit, at this time, the INPUT1+ and the INPUT 1-interface of the safety IO module are conducted with the normally closed contact 1 of the emergency stop button of the robot demonstrator through the pair of conductive pin shells 21 on the left side, and simultaneously, the INPUT2+ and the INPUT 2-interface of the safety IO module are conducted with the normally closed contact 2 of the emergency stop button of the robot demonstrator through the pair of conductive pin shells 21 on the right side, so that the emergency stop button of the demonstrator is in a normal working state.

In the present application, since the conductive pin housing 21 is cylindrical, the insulating pad 22 is easily slid in the conductive pin housing 21, thereby improving the sliding flexibility of the insulating pad.

In the present application, since the insulating bush housing 22 includes the end portions 221 at both ends, and the end portions 221 are inserted into the conductive pin housing 21 from the opening portion upward, the insulating bush housing can be restrained in the conductive pin housing 21 without easily slipping out from the opening portion.

In the present application, the frustoconical wrap spring is pagoda-shaped and can be more conveniently and quickly secured to the conductive pin housing 21.

In the present application, the conductive pin housings 21 made of copper material can provide the conductive properties of the conductive pin housings 21.
