Description

Technical Field

[0001] This utility model relates to the technical field of network communication connectors, and specifically to a non-standard connector structure with detection function and its connector. Background Technology

[0002] With the rapid development of information technology, the application of electronic and communication products has become increasingly widespread. The progress of communication equipment and related peripheral industries is also changing rapidly. The widespread use of communication equipment, coupled with the rapid development of network technology, allows for the quick acquisition of necessary communication data and the provision of diverse information services. Today's Internet continues to develop rapidly, and the technology used for network transmission is becoming more and more advanced and powerful, placing higher demands on the versatility of connectors. RJ-12 is used in systems that require multiple lines or complex signals, such as commercial telephone exchanges and push-button telephone systems, which support multi-line control or data transmission.

[0003] There are many types of existing RJ-12 connectors (PLUGs), and the coupling adaptation requirements for RJ-12 connectors are higher. Traditional RJ-12 detection terminals adopt a horizontal flat design. When non-standard connectors (such as those with out-of-tolerance dimensions or insufficient terminal height) are inserted, the detection terminals are excessively pressed down, causing them to break contact with the shorting terminals and falsely triggering a disconnect signal. The shell height tolerance of non-standard plugs often reaches + / -0.3mm, resulting in unstable contact pressure of the detection terminals. Traditional planar structures cannot adaptively compensate for this. Therefore, when non-standard RJ-12 connectors are inserted into RJ-12 connectors, it may cause the internal pins of the RJ-12 connector to fail to make contact or disconnect, resulting in electronic devices using RJ-11 connectors not operating normally or having their communication signals interfered with. It may even damage the electronic devices as a result. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a non-standard mating terminal structure and connector with detection function, thereby improving the stability of network equipment, protecting electronic products from damage, and enhancing the security of communication electronic equipment. This is achieved by setting a first to sixth set of limiting grooves on the terminal limiting plate, with the height of the first and sixth sets of limiting grooves being at least 1.35mm greater than the middle four sets. Combined with the support block inside the insulating connector base supporting the bottom of the arched portion of the PIN1 to PIN6 connecting terminals, a force-bearing support point is formed. This, along with the 158°–161° inclination angle formed by the bent end of the arched portion of the PIN1 / PIN6 connecting terminals and the contact portion, and an initial elastic stroke of ≥1.2mm (maintaining a process margin of ≥0.5mm even when the non-standard plug is fully seated), solves the problem of excessive pressure on the detection terminal during non-standard plug insertion, which could lead to false triggering of a disconnect signal or insufficient contact pressure. To address the issues of unstable connection and signal terminal contact, this system prioritizes contact between the detection terminal and the plug. When pressed down to the working plane, the arched section's elastic deformation generates a horizontal force to offset pressure loss and maintain stable contact pressure, ensuring accurate connection and disconnection of the detection circuit when a non-standard plug is inserted. The system utilizes a multi-positioning structure: matching the detection limit hole with the detection limit part on the detection plate; positioning protrusions on both sides working with the terminal limit plate to prevent misalignment; the terminal limit block's mounting groove and limit groove engaging with the horizontal limit protrusions of PIN2-PIN5; and the multiple positioning structures of the limit strips on both sides of the insulating connector, the connection positioning part, and the fixing piece within the limit cavity. This solves the problems of component misalignment, poor floating height, and poor contact caused by insufficient assembly precision in traditional connectors. It ensures accurate relative positioning of the connector when picking up components from the upper board and guarantees precise signal terminal installation and positioning, achieving stable and reliable contact between the signal terminal and the detection terminal when a non-standard plug is inserted.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A connector with detection function includes an insulating connector base. One side of the insulating connector base has a mating port for receiving a plug. Opposite the mating port is a PIN mounting port for mounting an RJ12-PIN connector terminal. A terminal limiting plate is provided on the PIN mounting port for positioning the RJ12-PIN connector terminal. A connection positioning part is provided on each side of the terminal limiting plate for positioning during the installation of the insulating connector base. A heat dissipation vent is provided on the terminal limiting plate for heat dissipation inside the insulating connector base. A limiting cavity is provided on the heat dissipation vent, and a [missing information - likely a device or component] is disposed within the limiting cavity. A fixing plate is provided for quick insertion when installing the insulating connector. A limiting strip is provided on each side of the insulating connector for limiting the position when installing the insulating connector.

[0009] A non-standard mating terminal structure for a connector with detection function includes a terminal limiting block tightly connected to a PIN mounting port, an RJ12-PIN terminal group embedded in the terminal limiting block, and a detection chip disposed on the terminal limiting plate. One end of the RJ12-PIN terminal group extends out of the PIN mounting port of the insulating connector and is electrically connected to the circuit board. When the plug is inserted into the mating port of the insulating connector, the RJ12-PIN terminal group abuts against the plug, thus making the circuit conductive.

[0010] The RJ12-PIN terminal group includes a PIN1 connection terminal, a PIN2 connection terminal, a PIN3 connection terminal, a PIN4 connection terminal, a PIN5 connection terminal, and a PIN6 connection terminal. The PIN1 connection terminal and the PIN6 connection terminal contact with the detection chip to make the circuit conductive.

[0011] The PIN1 connection terminal includes an integrally formed PIN1 output portion, a PIN1 connection portion extending downward from the PIN1 output portion, a PIN1 horizontal portion extending horizontally after being bent from the PIN1 connection portion, a PIN1 arched portion extending upward from the PIN1 horizontal portion, and a PIN1 contact portion extending after being bent from the PIN1 arched portion. The angle formed between the bent end of the PIN1 arched portion and the PIN1 contact portion is θ. The PIN2 connection terminal includes an integrally formed PIN2 output portion, a PIN2 connection portion extending upward from the PIN2 output portion, a PIN2 horizontal portion extending horizontally after being bent from the PIN2 connection portion, a PIN2 arched portion extending upward from the PIN2 horizontal portion, and a PIN2 contact portion extending after being bent from the PIN2 arched portion. The PIN3 connection terminal includes an integrally formed PIN3 output portion, a PIN3 connection portion extending downward from the PIN3 output portion, a PIN3 horizontal portion extending horizontally after being bent from the PIN3 connection portion, a PIN3 arched portion extending upward from the PIN3 horizontal portion, and a PIN1 contact portion extending from the bent end of the PIN1 arched portion. The PIN4 connection terminal includes an integrally formed PIN4 output portion, a PIN4 connection portion extending upward from the PIN4 output portion, a PIN4 horizontal portion extending horizontally after being bent from the PIN4 connection portion, a PIN4 arched portion extending upward from the PIN4 horizontal portion, and a PIN4 contact portion extending after being bent from the PIN4 arched portion; the PIN5 connection terminal includes an integrally formed PIN5 output portion, a PIN5 connection portion extending downward from the PIN5 output portion, a PIN5 horizontal portion extending horizontally after being bent from the PIN5 connection portion, a PIN5 arched portion extending upward from the PIN5 horizontal portion, and a PIN5 contact portion extending after being bent from the PIN5 arched portion; the PIN6 connection terminal includes an integrally formed PIN6 output portion, a PIN6 connection portion extending upward from the PIN6 output portion, a PIN6 horizontal portion extending horizontally after being bent from the PIN6 connection portion, a PIN6 arched portion extending upward from the PIN6 horizontal portion, and a PIN6 contact portion extending after being bent from the PIN6 arched portion.

[0012] The horizontal portion of PIN1 includes a horizontal straight segment of PIN1 and a horizontal bent segment of PIN1 extending to one side from the horizontal straight segment of PIN1; the horizontal portion of PIN2 includes a horizontal straight segment of PIN2, a PIN2 limiting protrusion provided on the horizontal straight segment of PIN2, and a horizontal bent segment of PIN2 extending to one side from the horizontal straight segment of PIN2; the horizontal portion of PIN3 includes a horizontal straight segment of PIN3, a PIN3 limiting protrusion provided on the horizontal straight segment of PIN3, and a horizontal bent segment of PIN3 extending to one side from the horizontal straight segment of PIN3; the horizontal portion of PIN4 includes a horizontal straight segment of PIN4, a PIN4 limiting protrusion provided on the horizontal straight segment of PIN4, and a horizontal bent segment of PIN4 extending to one side from the horizontal straight segment of PIN4; the horizontal portion of PIN5 includes a horizontal straight segment of PIN5, a PIN5 limiting protrusion provided on the horizontal straight segment of PIN5, and a horizontal bent segment of PIN5 extending to one side from the horizontal straight segment of PIN5; the horizontal portion of PIN6 includes a horizontal straight segment of PIN6 and a horizontal bent segment of PIN6 extending to one side from the horizontal straight segment of PIN6.

[0013] One side of the terminal limiting block is provided with several terminal mounting slots that match the RJ12-PIN terminal group, and the other side of the terminal limiting block is provided with two limiting guide blocks. The limiting guide blocks are used to guide and limit the terminal limiting block when it is inserted into the PIN mounting port.

[0014] The terminal mounting slot has a limiting groove on its side.

[0015] The beneficial effects of this utility model are as follows: 1. By setting the first to sixth sets of limiting grooves on the terminal limiting plate and setting the height of the first and sixth sets of limiting grooves to be at least 1.35mm greater than the middle four sets, combined with the support block of the inner bottom of the insulating connector to support the bottom of the arched part of the PIN1 to PIN6 connecting terminals, a force support point is formed. With the 158° to 161° tilt angle formed by the bent end of the arched part of the PIN1 / PIN6 connecting terminal and the contact part, and the initial elastic stroke of ≥1.2mm (maintaining a process margin of ≥0.5mm when the non-standard plug is fully in place), the problem of excessive pressure of the detection terminal causing false triggering of disconnection signal, unstable contact pressure, and inability of signal terminal to make contact and conduction is solved when the non-standard plug is inserted due to dimensional deviation or insufficient terminal height. It realizes that when the detection terminal makes priority contact and is pressed down to the working plane, the horizontal component force generated by the elastic deformation of the arched part offsets the pressure loss and maintains stable contact pressure, ensuring accurate conduction and disconnection of the detection circuit when the non-standard plug is inserted. 2. By matching the detection limit hole with the detection limit part of the detection plate, and the positioning protrusions on both sides cooperating with the terminal limit plate to prevent displacement, combined with the terminal mounting groove and limit groove of the terminal limit block and the locking and positioning of the horizontal limit protrusion of PIN2-PIN5, as well as the multiple positioning structure of the limit strips on both sides of the insulating connector, the connection positioning part, and the fixing piece in the limit cavity, the problem of component misalignment, poor floating height and poor contact caused by insufficient assembly precision of traditional connectors is solved. This ensures that the relative position of the connector is accurate when picking up the upper board and ensures the precise installation and positioning of the signal terminal. It also achieves stable contact and reliability between the signal terminal and the detection terminal when non-standard plugs are inserted. Attached Figure Description

[0032] like Figure 9 As shown, the horizontal portion 4102 of PIN1 includes a horizontal straight segment 41020 of PIN1 and a horizontal bent segment 41021 of PIN1 extending to one side from the horizontal straight segment 41020 of PIN1; the horizontal portion 4112 of PIN2 includes a horizontal straight segment 41120 of PIN2, a PIN2 limiting protrusion 41122 provided on the horizontal straight segment 41120 of PIN2, and a horizontal bent segment 41121 of PIN2 extending to one side from the horizontal straight segment 41120 of PIN2; the horizontal portion 4122 of PIN3 includes a horizontal straight segment 41220 of PIN3, a PIN3 limiting protrusion 41222 provided on the horizontal straight segment 41220 of PIN3, and a horizontal bent segment 4122 of PIN3 extending to one side from the horizontal straight segment 41220 of PIN3. 1; The horizontal portion 4132 of PIN4 includes a horizontal straight segment 41320 of PIN4, a PIN4 limiting protrusion 41322 provided on the horizontal straight segment 41320 of PIN4, and a horizontal bent segment 41321 of PIN4 extending to one side from the horizontal straight segment 41320 of PIN4; The horizontal portion 4142 of PIN5 includes a horizontal straight segment 41420 of PIN5, a PIN5 limiting protrusion 41422 provided on the horizontal straight segment 41420 of PIN5, and a horizontal bent segment 41421 of PIN5 extending to one side from the horizontal straight segment 41420 of PIN5; The horizontal portion 4152 of PIN6 includes a horizontal straight segment 41520 of PIN6 and a horizontal bent segment 41521 of PIN6 extending to one side from the horizontal straight segment 41520 of PIN6.

[0033] like Figure 6-7 As shown, one side of the terminal limiting block 40 is provided with several terminal mounting slots 400 that match the RJ12-PIN terminal group 41, and the other side of the terminal limiting block 40 is provided with two limiting guide blocks 401. The limiting guide blocks 401 are used to guide and limit the terminal limiting block 40 when it is inserted into the PIN mounting port 11; each terminal mounting slot 400 has a limiting groove 4000 on its side.

[0034] Furthermore, PIN1 connection terminal 410 and PIN6 connection terminal 415 are detection terminals, and PIN2 connection terminals 411 to PIN5 connection terminals 414 are signal terminals. The limiting grooves 120 of the terminal limiting plate 12 are set as the first to sixth groups. When PIN1 connection terminal 410 and PIN6 connection terminal 415 are respectively installed in the first group of limiting grooves 120 and the sixth group of limiting grooves 120, the height of the first group of limiting grooves 120 and the sixth group of limiting grooves 120 is greater than that of the middle four groups. The first group of limiting grooves 120 and the sixth group of limiting grooves 120 are at least 1.35mm higher than the other four limiting grooves 120, providing a physical height difference between the detection terminals and the signal terminals. The PIN1 contact portion 4104 and the PIN6 contact portion 4154 are raised, with a lifting height ΔH. (0.8-1.0mm), and abuts against the contacts at both ends of the detection chip 42. Before the plug 2 is inserted, the PIN1 connection terminal 410 and the PIN6 connection terminal 415 are short-circuited and conductive. The contact point of the detection terminal is 0.8-1.0mm (preferably 0.85mm) higher than the intermediate signal terminal. When the plug 2 is inserted, it makes priority contact, causing the PIN1 connection terminal 410 and the PIN6 connection terminal 415 to disconnect. Here, the detection terminal contact logic guarantee mechanism is: A [non-standard plug inserted] --> B {detection terminal makes priority contact} B --> C [terminal pressed down to the working plane] --> D [non-standard plug maintains contact pressure with the signal terminal] --> E[Detection circuit maintains conduction state] When the non-standard plug is inserted, its top first contacts the raised detection terminal. During the downward pressing of the detection terminal, its contact part tilts forward at a certain angle, generating a horizontal component force F to offset the pressure loss caused by the insufficient size of plug 2. When plug 2 is fully in place, the elastic stroke of the arched part of the detection terminal (initial state ≥1.2mm) still maintains a process margin of ≥0.5mm to ensure the contact pressure between the contact part and plug 2.

[0035] Assembly principle: First, install the RJ12-PIN terminal group 41 into the terminal mounting slot 400 of the terminal limiting block 40. Specifically, insert the horizontal part 4102 of PIN1 connecting terminal 410 into the first set of terminal mounting slots 400, insert the horizontal part 4112 of PIN2 connecting terminal 411 into the second set of terminal mounting slots 400, and make the PIN2 limiting protrusion 41122 engage with the limiting groove 4000. The P of PIN3 connecting terminal 412... The horizontal portion 4122 of PIN3 is inserted into the third set of terminal mounting slots 400, and the PIN3 limiting protrusion 41222 is engaged in the limiting groove 4000. The horizontal portion 4132 of PIN4 connecting terminal 413 is inserted into the fourth set of terminal mounting slots 400, and the PIN4 limiting protrusion 41322 is engaged in the limiting groove 4000. The horizontal portion 4142 of PIN5 connecting terminal 414 is inserted into the fifth set of terminal mounting slots 400, and the PIN5 limiting protrusion... 41422 is inserted into the limiting groove 4000, and the horizontal part 4152 of PIN6 of the PIN6 connecting terminal 415 is inserted into the sixth set of terminal mounting slots 400; next, the detection piece 42 is fitted onto the detection limiting part 121, so that the contacts at both ends of the detection piece 42 abut against the contact part 4104 of PIN1 and the contact part 4154 of PIN6 respectively; next, the terminal limiting block 40, which has been assembled above, is inserted into the PIN mounting port 11, so that the bottom support block 18 holds the arched part 410 of PIN1. The bottom of 3 is lifted up, and the bottom support block 18 becomes the main support point for the PIN1 connection terminal 410 to be deformed by pressure. After insertion, the PIN1 contact part 4104 abuts against the end of the limiting groove 120 of the terminal limiting plate 12. If the PIN1 output part 4100 is soldered and fixed to the circuit board, it forms two combined force support points with the bottom support block 18, so that the PIN1 connection terminal 410 remains relatively stable when it is deformed by pressure. Then, the fixing piece 17 is inserted into the limiting cavity 16 to complete the fixing.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Therefore, without departing from the design spirit of the present utility model, any equivalent changes or modifications made by those skilled in the art to the structure, features and principles of the present utility model should fall within the protection scope of the patent application of the present utility model.
