Description

Technical Field

[0001] The utility model relates to the technical field of connector pin-out detection, in particular to a connector pin-out detection mechanism. Background Art

[0002] A connector is a component used to connect electronic devices, usually consisting of a plug and a socket. The plug is usually a component with metal contacts, while the socket is a matching receiving component. By inserting the plug into the socket, electronic devices can be electrically connected to transmit power, signals or data.

[0003] Currently, the method for detecting whether a connector has been ejected is usually to manually pull it out to confirm whether it has been ejected. However, manual detection is easily affected by factors such as individual subjective consciousness, vision, and experience, which may cause different operators to obtain inconsistent results. In addition, manual detection requires a certain amount of time and manpower costs. Especially in large-scale production, a large amount of manpower is required for detection, which increases production costs and time costs. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a connector pin-out detection mechanism, which solves the problem that manual detection is easily affected by individual subjective consciousness, vision, experience and other factors, which may cause different operators to obtain inconsistent results.

[0005] To achieve the above-mentioned object, the utility model provides the following technical solutions: a connector pin-out detection mechanism, comprising a plug connector, a plug, at least two pins, at least two probes and at least two pressure sensors;

[0006] The plug sleeve is arranged on the outside of the plug connector, at least two of the plug pins are arranged inside the plug, at least two of the probes are arranged inside the plug connector, and at least two of the pressure sensors are respectively installed inside at least two of the probes;

[0007] One end of at least two of the probes extends into the interior of at least two of the probes respectively, and one section of at least two of the insertion pins abuts against at least two pressure sensors respectively.

[0008] Furthermore, a connection port for inserting a working plug is provided on a side of the plug close to the connector;

[0009] The connection port is in a square shape.

[0010] Furthermore, at least two sheaths are installed inside the plug connector, and at least two of the sheaths are respectively connected to at least two probes.

[0011] Furthermore, one end of the pin passes through the sheath and is electrically connected to the probe.

[0012] Furthermore, the ends of the pin and the probe facing away from each other are both connected with connecting wires.

[0013] Furthermore, insulating leather covers are provided on the outer sides of the two connecting wires.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The connector pin-out detection mechanism sets a pressure sensor inside the probe, which contacts the pressure sensor through the pin and then applies a certain pressure to the pressure sensor. At this time, the probe and the pin are in a conductive state. On the contrary, if the pin is out of contact, the pressure sensor makes the pin and the probe unable to be conductive due to the pressure. The above judgment is used to transmit the conductive signal to the detection equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2 In this embodiment, a connector pin-out detection mechanism is used to detect whether the connector has a pin-out condition.

[0021] It includes a plug connector 1, a plug 2, at least two pins 3, at least two probes 4 and at least two pressure sensors 5; the plug 2 is sleeved on the outside of the plug connector 1, the at least two pins 3 are arranged inside the plug 2, the at least two probes 4 are arranged inside the plug connector 1, and the at least two pressure sensors 5 are respectively installed inside the at least two probes 4; one end of the at least two probes 4 respectively extends inside the at least two probes 4, and a section of the at least two pins 3 is respectively abutted against the at least two pressure sensors 5.

[0022] It should be noted that, in order to ensure that the pin 3 and the probe 4 are effectively connected, in this embodiment, one end of the pin 3 passes through the sheath 6 and is electrically connected to the probe 4.

[0023] In actual setting, when the plug connector 1 is normal, the pin 3 will not get loose and slide in the sheath 6. When the plug connector 1 is withdrawn, the pin 3 will slide in the sheath 6 because it is not fixed.

[0024] In addition, a pressure sensor 5 is provided inside the probe 4, which contacts the pressure sensor 5 through the pin 3, and then a certain pressure is applied to the pressure sensor 5. At this time, the probe 4 and the pin 3 are in a conductive state. On the contrary, if the pin 3 is retracted, the pressure on the pressure sensor 5 makes the pin 3 and the probe 4 unable to be conductive due to the pressure. The above judgment is used to transmit the conductive signal to the detection equipment.

[0025] It should be noted that, in order to ensure the stability of the connection between the plug 2 and the plug connector 1, in this embodiment, a connection port for inserting the plug 2 is provided on the side of the plug 2 close to the plug connector 1; the shape of the connection port is preferably square.

[0026] In actual settings, the square connector provides a larger contact area, which can increase the contact area between the plug 2 and the plug connector 1, thereby enhancing the stability and reliability of the connection. The design of the square connector can better guide the insertion of the plug 2, helping to ensure the correct alignment between the plug 2 and the plug connector 1, and avoiding incorrect or crooked insertion.

[0027] In detail, in order to ensure that the pin 3 and the probe 4 can be effectively connected, one end of the pin 3 in this embodiment passes through the sheath 6 and is electrically connected to the probe 4. The back ends of the pin 3 and the probe 4 are connected to the connecting wire 7, and the outer sides of the two connecting wires 7 are provided with insulating leather sheaths 8.

[0028] In actual settings, the two ends of the two connecting lines 7 are connected to the input end and the output end of the device respectively, and the detection is performed by detecting the conductive state of the device docking plug, which effectively increases the convenience of docking plug detection.

[0029] In summary, the connector pin-out detection mechanism, by arranging a pressure sensor 5 inside the probe 4, contacts the pressure sensor 5 through the pin 3, and then applies a certain pressure to the pressure sensor 5. At this time, the probe 4 and the pin 3 are in a conductive state. On the contrary, if the pin 3 is out of contact, the pressure sensor 5 makes the pin 3 and the probe 4 unable to conduct due to the pressure. The above judgment is used to transmit the conduction signal to the detection equipment.
