Description

Technical Field

[0001] This utility model relates to the field of board-end connector technology, and in particular to a board-end connector with a PIN pin stabilization. Background Technology

[0002] A board-end connector is an electronic component used to connect the internal and external circuits of a circuit board. Typically, one end is fixed on a printed circuit board (PCB), and the other end is connected to a cable or other circuit board. Its core function is to achieve efficient and stable signal or current transmission through mechanical fixation and electrical conduction. It is widely used in consumer electronics, communications, automotive and other fields.

[0003] Currently, in the use of board-end connectors, external circuit electronic components are often directly plugged into the connector by plugging and unplugging. However, regular inspection and maintenance of electronic components are essential. Therefore, the plugs inserted into the board-end connectors are frequently plugged and unplugged. Due to the small diameter and long length of the pins, repeated plugging and unplugging can easily cause the pins to bend due to the force applied during removal, affecting the normal use of the board-end connector. To address this issue, a board-end connector with stable pins is proposed. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by providing a board-end connector with a stable PIN pin.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a PIN pin-secured board-end connector, including a PCB board, on which at least one base is provided, and on one side of the base are multiple spaced pins, which are electrically connected to the PCB board.

[0006] A fixed seat is vertically installed at both ends of the top of the base, and a sleeve is installed on the side of the two fixed seats that are relatively close to each other. A rotating seat is rotatably installed inside the sleeve, and a connecting groove with a top opening is provided between the two rotating seats. A connecting shaft is installed at both ends of the connecting groove, and the other end of the connecting shaft is fixed to the rotating seat. Multiple PIN pins arranged at intervals are installed on the bottom of the connecting groove.

[0007] A push plate is provided at the bottom of the connecting groove, and at least two push rods arranged at intervals are connected to the bottom of the push plate. The other end of the push rods passes through the bottom of the connecting groove.

[0008] Preferably, the end of the push rod furthest from the push plate is mounted on the handle.

[0009] Preferably, a screw is threaded onto one of the fixing seats, an elastic rubber block is installed at one end of the screw near the connecting groove, and a screw head is connected to the other end of the screw.

[0010] Preferably, two annular electrode plates are coaxially mounted on the inner wall of the sleeve, and the electrode plates are connected to the pins via wires. Two pole posts are mounted on the outer wall of the rotating seat, and the pole posts correspond to and abut against the electrode plates, and the pole posts are connected to the pins via wires.

[0011] Preferably, an annular support is installed along the bottom edge of the PIN pin.

[0012] Preferably, the edge of the push plate is fitted with the inner wall of the connecting groove with a clearance, and the push plate has multiple through holes that correspond one-to-one with the support base.

[0013] Preferably, the bottom of the PCB board is covered with an outer shell, which is made of a heat spreader, and the PCB board has a number of spaced mounting holes that penetrate the outer shell.

[0014] The design scheme proposed in this utility model has the following beneficial effects in application:

[0015] 1. This utility model uses a push plate provided in the connecting groove. When the handle is pushed, the plug placed in the connecting groove can be smoothly pushed out of the connecting groove, avoiding damage to the PIN pin caused by brute force. At the same time, the through holes on the push plate correspond one-to-one with the support base and the gap fit between the push plate and the inner wall of the connecting groove also ensures that the push plate acts evenly.

[0016] 2. This utility model enables the free rotation of the connecting groove through the rotating seat and connecting shaft, which facilitates the adjustment of the orientation of the connecting groove according to the wiring direction and improves the adaptability of use; the design of the screw and rubber block can fix the position of the connecting groove and prevent accidental deflection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference 1- Figure 4 A pin-secured board-end connector includes a PCB board 1. A housing 18 is wrapped around the bottom of the PCB board 1. The housing 18 is made of a heat dissipation plate, which not only protects the PCB board 1 but also ensures good heat dissipation and prevents heat accumulation on the PCB board 1 from affecting its use. Several spaced mounting holes 19 are provided on the PCB board 1, which penetrate the housing 18 to allow the PCB board 1 to be mounted by bolts or screws.

[0024] like Figure 1 As shown, at least one base 2 is provided on the PCB board 1, and a plurality of spaced pins 3 are provided on one side of the base 2, and the pins 3 are electrically connected to the PCB board 1.

[0025] like Figure 2 and Figure 3 As shown, fixed seats 4 are vertically mounted at both ends of the top of the base 2, and sleeves 5 are installed on the relatively close sides of the two fixed seats 4. Rotating seats 8 are rotatably mounted inside the sleeves 5. A connecting groove 6 with a top opening is provided between the two rotating seats 8. Multiple spaced pins 13 are installed on the bottom of the connecting groove 6. Connecting shafts 7 are installed at both ends of the connecting groove 6, and the other end of the connecting shaft 7 is fixed to the rotating seat 8, allowing the connecting groove 6 to rotate freely on the base 2. This facilitates the connection of external circuit plugs according to... The wiring direction adjusts the orientation of the connection slot 6 to improve its adaptability during use. To ensure stable telecommunication transmission after the plug of the external circuit is connected to the connection slot 6, two annular electrode plates are coaxially installed on the inner wall of the sleeve 5. The electrode plates are connected to the pin 3 through wires. Two pole posts are installed on the outer wall of the rotating seat 8. The pole posts correspond to and abut against the electrode plates, and the pole posts are connected to the PIN pin 13 through wires. This ensures that no matter how the connection slot 6 rotates, the PIN pin 13 and the PCB board 1 can stably transmit electrical signals.

[0026] It should be noted that, in order to stabilize the connecting groove 6 after it is turned, a screw 9 is threaded onto one of the fixing seats 4. A flexible rubber block 10 is installed at one end of the screw 9 near the connecting groove 6, and a screw head 11 is connected to the other end of the screw 9. That is, after the connecting groove 6 is turned to the desired direction, the screw 9 can be turned to press the rubber block 10 against the side wall of the connecting groove 6, thereby tightening the connecting groove 6 to prevent the connecting groove 6 from accidentally deflecting during use and affecting the connected plug and wire.

[0027] Furthermore, such as Figure 4 As shown, an annular support base 12 is installed along the bottom edge of the PIN pin 13 to wrap the bottom end of the PIN pin 13, reducing the exposed part of the PIN pin 13, and improving the stress strength of the PIN pin 13 while ensuring the transmission of electrical signals.

[0028] like Figure 2 and Figure 4 As shown, when it is necessary to remove the plug connected to the connector 6, a push plate 14 is provided at the bottom of the connector 6. At least two push rods 16 are connected to the bottom of the push plate 14, and the other end of the push rod 16 passes through the bottom of the connector 6. The connector 6 can be placed on its side so that the opening of the connector 6 is horizontal. Then, the push rod 16 is pushed to move the push plate 14 toward the opening of the connector 6, thereby pushing out the plug connected to the connector 6. This prevents damage to the PIN pin 13 caused by forcibly pulling out the plug. The edge of the push plate 14 is fitted with the inner wall of the connector 6 with a clearance. Multiple through holes 15 are provided on the push plate 14, which correspond one-to-one with the support base 12. When the push plate 14 acts on the plug in the connector 6, it can fully act on the plug, allowing the plug to be pushed out of the connector 6 more easily and stably.

[0029] It should be noted that, in order to make the process of pushing out the plug easier, the end of the push rod 16 away from the push plate 14 is installed on the handle 17, which increases the force application area and improves the convenience of force application. In addition, multiple push rods 16 are connected to the same handle 17, which can limit the push rod 16 on the connecting groove 6 and prevent the push rod 16 from sliding out of the connecting groove 6 when it slides inward, thus affecting the subsequent use of the push plate 14.

[0030] Specifically, in actual use, to ensure that the plug of the external circuit can be securely placed on the connection slot 6, a locking groove (such as...) is provided on the connection slot 6. Figure 3 (The position indicated by the middle arrow A) and the plug is equipped with a buckle corresponding to the slot. When you need to remove the plug, you can first press the buckle with one hand to make it disengage from the slot, and then push the handle 17 with the other hand to push the plug out.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
