In order to clearly describe the travel switch and the travel switch assembly of the utility model, the travel switch assembly in the state of being applied in the plug-in self-test connector is taken as an example for description.

[0049] Specifically, the travel switch assembly comprises a travel switch 4 and a driving part 3, the driving part 3 is located radially outside the locking sleeve and has a driven end located radially outside the locking sleeve at the front side of the shell, the driving part 3 has the travel switch 4 connected at the rear side, and the travel switch 4 is switched during the rearward movement of the driving part. The driving part 3 is provided with a return spring providing an elastic force to the front side, the shell has a anti-falling stop structure for stopping the driving part 3, which can stop the driving part 3 at the front limit position when the return spring provides an elastic force to push the driving part 3 forward, and the driven end of the driving part 3 is used to be pushed back when the mating connector is inserted, and then the on-off state of the travel switch 4 is changed, that is, from the loop on state to the loop off state or vice versa, and the return spring pushes the driving part 3 forward to the front limit position when the mating connector is pulled out and the on-off state of the travel switch 4 is changed again.

[0050] As shown in the embodiment, Figures 1-4 The driving part 3 comprises a driven ring body 30, and the push rod of the travel switch 4 is connected at a certain position of the circumference of the driven ring body 30. As the name implies, the driven ring body 30 is a ring structure driven by the mating connector, the driven ring body 30 is arranged around the inner body 1 and the front end thereof constitutes the driven end, that is, when the mating connector is inserted, the mating connector can push the front end of the driven ring body 30 and move it backward. The shell is provided with a push rod through hole for the push rod to pass through, the travel switch 4 is located at the rear side of the driven ring body 30, and the travel switch state is switched when the driven ring body 30 moves backward and drives the push rod to move backward.

[0052] Regarding the structure of the travel switch and the connection thereof with the driven ring body, Figures 6-12In the shown embodiment, the push rod comprises a mounting rod 31, the rear end of the mounting rod 31 is provided with an insulated plate-shaped trigger end extending to the side of the switch body, the short-circuiting piece 43 is arranged on the plate-shaped trigger end, the switch body is located at the front side of the plate-shaped trigger end, the switch body is made of insulating material as a whole, and the pair of wiring terminals are arranged on the switch body. When the push rod moves rearward to the limit position, the short-circuiting piece 43 is away from the switch body, and the short-circuiting piece is simultaneously separated from the pair of wiring terminals. When the push rod moves forward to the limit position before resetting, the short-circuiting piece 43 is close to the switch body, and the short-circuiting piece is simultaneously in contact with the pair of wiring terminals.

Alternatively, in an embodiment, the short-circuiting piece is a T-shaped conductive sheet, one end of the T-shaped conductive sheet located in the middle position is fixedly connected to the push rod, the other two ends of the conductive sheet are located on the side of the push rod, and the pair of wiring terminals are arranged on the switch body. The other two ends of the conductive sheet are respectively used for cooperating with the two wiring terminals.

[0053] In Figures 6-12 In the shown embodiment, in order to adapt to the application in the circular connector and reduce the occupied space as much as possible, the switch body comprises an arc-shaped strip-shaped main component 402, the circumferential surface of the arc-shaped strip-shaped main component 402 is perpendicular to the axis of the push rod, the push rod is located on the side of the arc-shaped strip-shaped main component 402 away from the center of the circle, and actually the arc-shaped strip-shaped main component 402 is coaxially arranged with the driven ring body 30. From the axial perspective, the main component 402 is located on the radial inner side of the driven ring body 30. Such a structure can make the switch body better adapt to the internal body of the circular connector, and can ensure the compact radial size as much as possible while reducing the axial occupied space. Of course, when applied to a rectangular connector, the switch body is arranged in a straight line type long strip shape.

[0054] In an embodiment, the pair of wiring terminals can be arranged side by side in the radial direction or the width direction of the main component. In the embodiment shown in the drawings of the present application, the pair of wiring terminals are arranged at intervals in the arc length direction of the main component 402, so as to reduce the radial size or width size of the main component 402 as much as possible. The wiring terminal can be a sheet-shaped terminal, one side of the sheet-shaped terminal faces backward and is used for abutting and cooperating with the block-shaped short-circuiting piece, and the other side faces forward and is used for welding the wire. In other embodiments, the wiring terminal is a columnar terminal, one end of the columnar terminal faces backward and is used for abutting and cooperating with the block-shaped short-circuiting piece, and the other end faces forward and is used for welding or crimping the wire.

In this way, the terminal can lead the wire from the rear side, facilitating the connection and leading of the wire.

[0055] In one embodiment, the rear end of the first parallel edge and the shorting member can be in an abutting matching relationship, such as the first parallel edge being a conductive column and the shorting member being a long strip-shaped conductive block, the front side of the long strip-shaped conductive block being capable of simultaneously contacting the conductive columns of two terminals. In this way, the shorting member can be matched with the terminals in a more reliable way, which can avoid the travel switch from sending false signals in some vibration environments. Figures 6-11 In the shown embodiment, the first parallel edge and the shorting member 43 are in a pin-hole plug-in matching, that is, one of the first parallel edge and the shorting member contains a socket structure, and the other contains a pin structure. The pin-hole plug-in matching is more reliable, which can avoid the travel switch from sending false signals in some vibration environments. Alternatively, the first parallel edge is a socket 410, and the shorting member 43 is a U-shaped pin structure, the two parallel edges of the U-shaped pin structure being matched with the first parallel edges of two terminals respectively. When the terminals are arranged in pairs, the two parallel edges of the terminals are also arranged side by side in the length direction of the main body component, which can also reduce the radial or width dimension of the main body component. Moreover, preferably, the terminals of the two terminals are arranged at positions away from each other in the length direction of the main body component, that is, the first parallel edges of the two terminals matched with the shorting member 43 are arranged close to each other, which can reduce the size of the shorting member. When the first parallel edge adopts the socket 410, the rear end of the socket 410 can extend out of the main body component, or as shown in Figures 8-10 As shown, the socket 410 is entirely embedded in the main body component 402, which can achieve better protection.

[0056] In one embodiment, the terminal can be directly injection molded in the main body component 402 or adhesively fixed in the main body component 402. In Figure 10 In the shown embodiment, it can be clearly seen that the main body component 402 has a mounting groove, the mounting groove includes a transverse groove segment arranged on the front side of the main body component 402 and longitudinal groove segments communicated with both ends of the transverse groove segment, the longitudinal groove segments extend backward and penetrate through the main body component 402, the terminal is inserted into the mounting groove from the front side, and the front side of the main body component 402 is connected with an insulating baffle 401, which keeps the terminal constrained in the main body component 402 through the insulating baffle 401. The two ends of the main body component 402 are penetrated by fixing screws, which are used to fix the switch body on the relevant equipment, and in this document, the switch body is fixed on the connector housing through the fixing screws.

[0057] In one embodiment, the plate-shaped trigger end is an integral overhanging plate, and the shorting member 42 can be directly injection molded on the plate-shaped trigger end, or glued or forcibly fixed on the plate-shaped trigger end. Figure 8 、 9 In the embodiment shown in FIG. 11, the plate-shaped trigger end comprises a main plate body 311 and a back plate 312, the main plate body 311 is provided with a U-shaped mounting cavity 313 for the shorting member 42 to be mounted from the back to the front, the connecting screw 34 passes through the back plate 312 and the main plate body 311 from the back to the front in sequence and is connected with the threaded hole at the rear end of the mounting rod 31, and the connecting screw 34 presses the main plate body 311 and the back plate 312 against the rear end of the mounting rod 31.

[0058] In order to realize the reset of the push rod in the travel switch, as shown in Figures 4-7 In one embodiment, the rear side of the driving component is connected with a guide rod 39, and the housing is provided with a guide mounting hole for the guide rod 39 to pass through, so that the driving component can be guided to move along the plugging direction of the connector relative to the connector housing, the rear end of the guide rod 39 has an outward turning edge, the outward turning edge is in abutting engagement with the rear end hole of the guide mounting hole, the rear end of the guide rod 39 is provided with a blind hole, the front end of the reset spring 32 is inserted into the blind hole, and the rear end is abutted against the tail housing component 90, so as to provide the driving component with an elastic force in the forward direction.

[0059] In some embodiments, the driven ring body 30 can be a common integral ring structure. In the plug-in detection connector, when the adapter plug is connected with the socket in a locking manner, the locking nut of the adapter plug gradually pushes the driven ring body 30 during the process of being screwed onto the locking sleeve. At this time, since the locking nut performs a rotating forward movement, in order to reduce the frictional resistance of the locking nut during the rotation and to avoid the abrasion of the driven ring body 30, as shown in one embodiment in Figure 6 、 7 The driven ring body 30 comprises a connecting ring body 301 and a rotating ring body 302, the rotating ring body 302 is arranged at the front side of the connecting ring body 301 in a rotating manner about its own axis, the connecting ring body 301 is connected with the mounting rod 31, and the front end face of the rotating ring body 302 constitutes the driven end. In this way, during the process that the locking nut abuts against the rotating ring body 302 and pushes it to move backward, the rotating ring body 302 can rotate itself, which to some extent reduces the friction between the locking nut and the driven ring body 30.

[0060] The relative rotating assembly manner between the rotating ring body 302 and the connecting ring body 301 is not limited, for example, the connecting ring body 301 is a circular ring with a square cross section, the rotating ring body 302 is a ring structure which is bent from a thin wall and has a C-shaped cross section with an opening facing the back, the C-shaped opening avoids the connection between the mounting rod 31 and the connecting ring body 301, and the rotating ring body 302 is wrapped around the connecting ring body 301 and can rotate freely relative to the rotating ring body 302.Figure 12 In the shown embodiment, the driven ring body 30 comprises a thrust bearing, two thrust washers of which constitute the rotary ring body 302 at the front side and the connecting ring body 301 at the rear side. The rotary ring body 302 and the connecting ring body 301 are formed by using the existing mature thrust bearing, which is convenient to obtain and simple to manufacture. In order to avoid the two thrust washers from being scattered freely, the driven ring body 30 in the embodiment further comprises a retaining member 303 for retaining a certain front-rear distance between the two thrust washers.
