Description

Technical Field

[0001] This utility model relates to the field of plug-in quick-connect industrial control instrument technology, and in particular to a plug-in quick-connect industrial control instrument. Background Technology

[0002] Plug-in industrial control instruments are automated devices designed for quick installation and maintenance. They typically have standardized interfaces that allow users to plug or unplug instrument modules from the control system without tools.

[0003] In the existing plug-in industrial control instrument wiring process, the feedback obtained from interface insertion is low, making it difficult for operators to know whether the interface is fully inserted. Incomplete insertion may cause poor contact, affecting the normal use of the instrument.

[0004] Therefore, to address the above issues, a plug-in quick-connect industrial control instrument can be designed, with improvements to the interface to increase the feedback during insertion. Utility Model Content

[0005] To overcome the problem that most pluggable industrial control instruments have low feedback during cable connection, making it difficult for operators to know whether the interface is fully inserted, which may lead to incomplete insertion and poor contact, affecting the normal use of the instrument.

[0006] The technical solution of this utility model is as follows: a plug-in quick-connect industrial control instrument, including an instrument body, external wiring, a connector, a first spring, a feedback bead, a dust cover, a torsion spring, an adapter, and a prompting plate; a connector is provided at the interface of the instrument body, a first spring is provided on the inner side of the connector, a feedback bead is provided at one end of the first spring, a dust cover is provided on one side of the connector, a torsion spring is provided on one side of the dust cover, an adapter is provided at the insertion end of the connector, a prompting plate is provided on the inner side of the adapter, and an external wiring is provided at the insertion end of the adapter.

[0007] Preferably, by setting one end of the adapter to connect the external wiring and the other end to the connector, the external wiring is connected to the instrument body. The first spring pushes the feedback bead to collide with the adapter during insertion to generate feedback. The torsion spring drives the dust cover to move. After full insertion, feedback is generated again to prevent the connection from loosening. The indicator board makes it easy for the operator to know whether the external wiring is fully inserted into the adapter.

[0008] Preferably, a feedback hole is provided on the inner side of the connector, and the feedback bead is located at the inner opening of the feedback hole, with the opening of the feedback hole narrowed; the narrowed feedback hole prevents the feedback bead from sliding out of the feedback hole.

[0009] Preferably, the feedback holes are divided into two groups, with the feedback holes in the same group arranged equidistantly around the inner hole of the connector, and the distance between the two groups of feedback holes is less than the length of the adapter interface; the two groups of feedback holes can provide two feedback sensations, the first prompting the operator to provide feedback in the form of feedback, and the second prompting that the connection is complete.

[0010] Preferably, two sets of rotating seats are provided above the connector. One end of the dust cover is rotatably connected to the rotating seat, and the other end of the dust cover is provided with a buckle. The dust cover is rotatably connected to the connector by the rotating seats, so that the dust cover can generate feedback again by the buckle when fully connected and prevent the connection from loosening.

[0011] Preferably, the interface end of the adapter is provided with two sets of feedback slots, and the spacing between the feedback slots is the same as the distance between the two sets of feedback holes; the first spring can release energy through the feedback slots to push the feedback bead to collide with the adapter to generate feedback.

[0012] Preferably, the insertion end of the adapter has a limiting groove and an observation window. The observation window has a sliding groove, the length of which is greater than the length of the indicator plate. The engagement of the limiting groove and the buckle generates feedback and prevents the connection from becoming loose. The observation window allows for easy viewing of the indicator plate status to determine whether the external wiring is fully inserted into the adapter.

[0013] Preferably, the indicator plate is located within the sliding groove and is slidably connected to the adapter. A limit plate is provided on the outer side of the indicator plate, and different indicators are written on the indicator plates on both sides of the limit plate. The indicator plate is slidably connected to the adapter via the sliding groove, allowing the indicator plate to change its indicators during the insertion of the external wiring.

[0014] Preferably, a sliding plate is provided on the inner side of the indicator panel, and a second spring is provided on one side of the indicator panel. The deformation direction of the second spring is consistent with the sliding direction of the indicator panel; the indicator panel is pushed to reset by the second spring after the external wiring is pulled out.

[0015] The beneficial effects of this utility model are:

[0016] 1. Compared to the traditional plug-in industrial control instrument wiring connection process, the feedback obtained from interface insertion is low, making it difficult for operators to know whether the interface is fully inserted. Incomplete insertion may cause poor contact, affecting the normal use of the instrument. This device adds an insertion feedback mechanism so that the operator can get clear feedback when the cable is fully inserted, preventing incomplete cable insertion from causing poor disconnection and affecting the use of the control instrument. The feedback mechanism also provides a certain limit capability to prevent the interface from loosening.

[0017] 2. When inserting the cable, insert the external cable into the interface end of the adapter. The interface end of the adapter is the same as that of a regular connector and is compatible with ordinary cable interfaces. The insertion process of the external cable will push the sliding plate to move, causing the indicator plate to slide in the sliding groove and the limit plate to move in the observation window. The operator can check the position of the limit plate in the observation window or the indicator plate visible in the observation window to know whether the external cable is fully inserted. After the external cable is pulled out, the second spring can push the indicator plate to reset. Then insert the insertion end of the adapter into the connector. When the adapter is just inserted, it will push the feedback bead to move in the feedback hole and compress the first spring. When the set of feedback grooves near the insertion end of the adapter moves to the outermost position... When a set of feedback beads is in position, the first spring releases energy to quickly push the feedback beads. The collision between the feedback beads and the adapter will generate vibration and sound, providing feedback to the operator. As the adapter is inserted further until it is fully inserted, all the feedback beads will collide with the adapter, generating greater vibration and sound, providing feedback to the operator that the connection is fully inserted. At the same time, the engagement of the feedback beads with the feedback slot can provide some limiting function to prevent the connection from becoming loose. This addresses the issue that in most pluggable industrial control instruments, the feedback obtained from the interface insertion during the wiring process is low, making it difficult for the operator to know whether the interface is fully inserted. This may result in incomplete insertion, causing poor contact and affecting the normal use of the instrument.

[0018] 3. During the connection process, the dust cover will cover the connector interface before insertion to prevent foreign objects from entering. After the connection is complete, the dust cover will be snapped into the limit groove by the torsion spring, further providing feedback to the operator that the insertion is complete, while increasing the strength of the limit.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1-5 This utility model provides an embodiment: a plug-in quick-connect industrial control instrument, including an instrument body 1, external wiring 2, a connector 3, a first spring 4, a feedback bead 5, a dust cover 6, a torsion spring 7, an adapter 8, and a prompting plate 9; the connector 3 is provided at the interface of the instrument body 1, the first spring 4 is provided on the inner side of the connector 3, the feedback bead 5 is provided at one end of the first spring 4, the dust cover 6 is provided on one side of the connector 3, the torsion spring 7 is provided on one side of the dust cover 6, the adapter 8 is provided at the insertion end of the connector 3, the prompting plate 9 is provided on the inner side of the adapter 8, and the external wiring 2 is provided at the insertion end of the adapter 8.

[0027] Please see Figure 2 In this embodiment, a feedback hole 301 is provided on the inner side of the connector 3. The feedback bead 5 is located at the inner opening of the feedback hole 301. The opening of the feedback hole 301 is narrowed to prevent the feedback bead 5 from sliding out of the feedback hole 301. The feedback hole 301 is divided into two groups. The feedback holes 301 in the same group are arranged equidistantly around the inner hole of the connector 3. The distance between the two groups of feedback holes 301 is less than the length of the adapter 8 interface. The two groups of feedback holes 301 can provide two feedback sensations. The first is to prompt the operator to provide feedback, and the second is to indicate that the connection is complete.

[0028] Please see Figure 3 In this embodiment, two sets of rotating seats 302 are provided above the connecting seat 3. One end of the dust cover 6 is rotatably connected to the rotating seat 302, and the other end of the dust cover 6 is provided with a buckle 601. The dust cover 6 is rotatably connected to the connecting seat 3 by the rotating seat 302, so that the dust cover 6 can generate feedback again by using the buckle 601 when fully connected and prevent the connection from loosening.

[0029] Please see Figure 4In this embodiment, the interface end of the adapter 8 is provided with two sets of feedback slots 801. The spacing between the feedback slots 801 is the same as the distance between the two sets of feedback holes 301. The first spring 4 can release energy through the feedback slots 801 to push the feedback bead 5 to collide with the adapter 8 to generate feedback. The insertion end of the adapter 8 is provided with a limiting slot 802 and an observation window 803. The observation window 803 is provided with a sliding slot 804. The length of the sliding slot 804 is greater than the length of the indicator plate 9. The limiting slot 802 and the buckle 601 are engaged to generate feedback again and prevent the connection from becoming loose. The observation window 803 is used to easily check the status of the indicator plate 9 and to know whether the external wiring 2 is fully inserted into the adapter 8.

[0030] Please see Figure 5 In this embodiment, the prompting plate 9 is located in the sliding groove 804 and is slidably connected to the adapter 8. A limit plate 901 is provided on the outer side of the prompting plate 9. Different prompts are written on the prompting plates 9 on both sides of the limit plate 901. The prompting plate 9 is slidably connected to the adapter 8 through the sliding groove 804, so that the prompting plate 9 can change the prompts during the insertion of the external wiring 2. A sliding plate 903 is provided on the inner side of the prompting plate 9, and a second spring 902 is provided on one side of the prompting plate 9. The deformation direction of the second spring 902 is consistent with the sliding direction of the prompting plate 9. The second spring 902 pushes the prompting plate 9 to reset after the external wiring 2 is pulled out.

[0031] When inserting the cable, insert the external cable 2 into the interface end of the adapter 8. The interface end of the adapter 8 is the same as that of a regular connector and is compatible with ordinary cable interfaces. The insertion process of the external cable 2 will push the sliding plate 903 to move, causing the indicator plate 9 to slide in the sliding groove 804 and the limit plate 901 to move in the observation window 803. The operator can check the position of the limit plate 901 in the observation window 803 or the indicator plate 9 visible in the observation window 803 to know whether the external cable 2 is fully inserted. After the external cable 2 is pulled out, the second spring 902 can push the indicator plate 9 to reset. Then, insert the insertion end of the adapter 8 into the connector 3. When the adapter 8 is first inserted, it pushes the feedback bead 5 to move in the feedback hole 301 and compresses the first spring 4. When a set of feedback slots 801 near the insertion end of the adapter 8 moves to the position of the outer set of feedback beads 5, the first spring 4 releases energy to quickly push the feedback bead 5. The collision between the feedback bead 5 and the adapter 8 will generate vibration and sound, providing feedback to the operator. When the adapter 8 is fully inserted, all the feedback beads 5 will collide with the adapter 8, generating greater vibration and sound, providing feedback to the operator that it is fully inserted. At the same time, the engagement of the feedback bead 5 with the feedback slot 801 can provide some limiting function to prevent the connection from becoming loose.

[0032] During the connection process, the dust cover 6 will cover the interface of the connector 3 before insertion to prevent foreign objects from entering. After the connection is complete, the dust cover 6 will be engaged in the limiting groove 802 by the action of the torsion spring 7, which will further provide feedback to the operator that the insertion is complete and increase the strength of the limiting.

[0033] Through the above steps, by setting one end of the adapter 8 to connect the external wiring 2 and the other end to the connector 3, the external wiring 2 is connected to the instrument body 1. The first spring 4 pushes the feedback bead 5 to collide with the adapter 8 during the insertion process to generate feedback. The torsion spring 7 drives the dust cover 6 to move. After full insertion, feedback is generated again to prevent the connection from becoming loose. The indicator plate 9 makes it easy for the operator to know whether the external wiring 2 is fully inserted into the adapter 8.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
