Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to an emergency power supply quick access electrical connector. Background Technology

[0002] An electrical connector is a common electronic device that enables the transmission of current and / or signals through the contact of its terminals. Electrical connectors typically consist of a male connector and a female connector, each with its own built-in terminals. By inserting or removing the male and female connectors, the terminals between them are connected or disconnected, thus enabling or discontinuing the transmission of current and / or signals.

[0003] Existing electrical connectors use either clearance fit or interference fit when the male and female connectors are mated together. Clearance fits, in the absence of adequate support structures, can become loose, compromising electrical connection performance. When using emergency power supply equipment, it is necessary to ensure both connection stability and rapid connection. Therefore, an improved emergency power supply quick-connect electrical connector is proposed. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide an emergency power supply quick access electrical connector to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an emergency power supply quick-access electrical connector, including a female connector and a male connector. A connecting pin is fixedly connected to the end of the male connector. A connecting groove is provided inside the female connector, and a locking groove is formed on the inner side of the female connector. A mounting box is fixedly connected to the side of the male connector. A guide rod is fixedly connected inside the mounting box. A pressure plate is sleeved on the guide rod. A locking block protruding from one end of the mounting box is fixedly connected to one end of the pressure plate. A pressing hole is formed at the other end of the mounting box. A first spring is fixedly connected to the inner side of the locking block, and a second spring is fixedly connected to the inner side of the pressure plate away from the locking block.

[0007] Preferably, in any of the above solutions, the rear ends of both the male and female connectors are provided with connecting lines, and transition plates are provided between the connecting lines and the male and female connectors.

[0008] The above technical solution involves a female connector and a male connector forming the basic components of an electrical connector, which, when connected, enable current transmission. During emergency power supply, the emergency circuit is connected to the electrical equipment to provide power. A transition plate is placed between the male and female connectors and the connecting wires to improve the bending resistance of the cable ends.

[0009] Preferably, in any of the above solutions, the front corners of the male connector are rounded, and the inner corners of the female connector are also rounded.

[0010] The above technical solution involves rounding the corners of both the male connector and the inner corners of the female connector, resulting in a smoother connection between them.

[0011] Preferably, the front end face of the mounting box is beveled, and mounting boxes are provided on both sides of the male connector.

[0012] The above technical solution provides installation space for components such as guide rods and pressure plates. The front face of the mounting box is beveled to allow for smoother insertion into the female connector. Mounting boxes are provided on both sides of the male connector, facilitating the installation of locking components on both sides.

[0013] Preferably, in any of the above solutions, the height of the locking groove is greater than half the thickness of the connecting female head, and the guide rod is positioned in the middle of the mounting box.

[0014] The above technical solution involves: a locking groove on the inner side of the female connector, which works with a locking block to secure the male connector. By controlling the height of the locking groove, a stable locking mechanism is achieved with the locking block. A guide rod is installed inside the mounting box to guide the pressure plate and prevent it from shifting in other directions. By pressing the pressure plate through the pressing hole, guided by the guide rod, the pressure plate moves into the mounting box, causing the locking block to move into the mounting box as well. This allows for the connection or disconnection of the male and female connectors.

[0015] Preferably, in any of the above embodiments, the outer surface of the locking block is beveled, and an elastic band is provided inside the pressing hole.

[0016] The above technical solution employs a beveled outer surface for the locking block, allowing it to automatically move into the locking groove under pressure. This enables connection of the male and female connectors even without pressing against the pressure plate, further simplifying the connection process. A first spring and a second spring are installed inside the pressure plate and locking block to provide elastic support, allowing the locking block to protrude from the mounting box. An elastic band is installed inside the pressing hole; this band can shield the pressure plate and deform under pressure, thus compressing it.

[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0018] 1. This emergency power supply quick-connect electrical connector, through its structure including a locking slot, mounting box, guide rod, pressure plate, locking block, pressing hole, first spring, and second spring, allows for quick and reliable connection between the male and female connectors. When connecting the male and female connectors, pressing the pressure plate through the pressing hole, guided by the guide rod, moves the pressure plate into the mounting box, causing the locking block to move inwards. Then, inserting the male connector into the female connector and releasing it causes the pressure plate and locking block to move outwards from the mounting box under the action of the first and second springs, locking the male connector into the locking slot. Pressing the pressure plate through the pressing hole retracts the locking block, enabling initial locking of the connector after insertion into the female connector without the need for external tools, resulting in a quick and more secure connection.

[0019] 2. This emergency power supply quick-connect connector features a transition plate between the male and female connectors and the connecting cable, which improves the bending resistance of the cable ends. The corners of the male connector and the inner corners of the female connector are rounded, resulting in a smoother connection between them. The outer surface of the locking block is beveled, allowing it to automatically move into the locking groove under pressure. This ensures connection even without pressing the pressure plate, further simplifying the connection process.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figures 1-4 As shown, this utility model includes a female connector 1 and a male connector 2. A connecting pin 3 is fixedly connected to the end of the male connector 2. A connecting groove 4 is provided inside the female connector 1, and a locking groove 5 is opened on the inner side of the female connector 1. An installation box 6 is fixedly connected to the side of the male connector 2. A guide rod 7 is fixedly connected inside the installation box 6. A pressure plate 8 is sleeved on the guide rod 7. A locking block 9 protruding from one end of the installation box 6 is fixedly connected to one end of the pressure plate 8. A pressing hole 10 is opened on the other end of the installation box 6. A first spring 11 is fixedly connected to the inner side of the locking block 9, and a second spring 12 is fixedly connected to the inner side of the pressure plate 8 away from the locking block 9.

[0030] Example 1: Both the male connector 2 and the female connector 1 have connecting wires at their rear ends, and transition plates are provided between the connecting wires and both the male connector 2 and the female connector 1. The female connector 1 and the male connector 2 cooperate to form the basic components of an electrical connector, enabling current transmission after connection. During emergency power supply, the emergency circuit is connected to the electrical equipment to supply power. The transition plates between the male connector 2, the female connector 1, and the connecting wires improve the bending resistance of the cable ends. The front corners of the male connector 2 and the inner corners of the female connector 1 are rounded. The rounded corners of the male connector 2 and the inner corners of the female connector 1 make the connection between the male connector 2 and the female connector 1 smoother.

[0031] Example 2: The front end face of the mounting box 6 is beveled, and mounting boxes 6 are provided on both sides of the male connector 2. The mounting box 6 provides installation space for components such as the guide rod 7 and the pressure plate 8. The beveled front end face of the mounting box 6 allows it to enter the female connector 1 more smoothly. The mounting boxes 6 on both sides of the male connector 2 provide conditions for setting up locking components on both sides of the male connector 2. The height of the locking groove 5 is greater than half the thickness of the female connector 1, and the guide rod 7 is located in the middle position inside the mounting box 6. The locking groove 5 is opened on the inner side of the female connector 1, which can cooperate with the locking block 9 to lock the male connector 2. By controlling the height of the locking groove 5, it can achieve stable locking with the locking block 9. The guide rod 7 is set in the mounting box 6, which can guide the pressure plate 8 and prevent the pressure plate 8 from displacing in other directions. Pressing the pressure plate 8 through the pressing hole 10, guided by the guide rod 7, the pressure plate 8 moves into the mounting box 6, driving the locking block 9 to move into the mounting box 6, thus enabling the connection or disconnection of the male connector 2 and the female connector 1.

[0032] Example 3: The outer surface of the locking block 9 is beveled, and an elastic band is provided inside the pressing hole 10. The beveled outer surface of the locking block 9 allows it to automatically move into the locking groove 5 after being pressed, enabling the connection of the male connector 2 and the female connector 1 even if the pressure plate 8 is not pressed during connection, further simplifying the connection process. A first spring 11 and a second spring 12 are provided inside the pressure plate 8 and the locking block 9 to provide elastic support between them, allowing the locking block 9 to protrude from the mounting box 6. An elastic band is provided inside the pressing hole 10, which can block the pressure plate 8 and deform to a certain extent after pressing, thereby squeezing the pressure plate 8.

[0033] The working principle of this utility model is as follows:

[0034] S1. When connecting the female connector 1 and the male connector 2, press the pressure plate 8 through the pressing hole 10. Under the guidance of the guide rod 7, the pressure plate 8 moves into the mounting box 6, which in turn moves the locking block 9 into the mounting box 6.

[0035] S2. Insert the male connector 2 into the female connector 1, release the male connector 2, and under the action of the first spring 11 and the second spring 12, the pressure plate 8 and the locking block 9 move outward from the mounting box 6, so that the locking block 9 is engaged in the locking groove 5, thereby securing the male connector 2.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] 1. This emergency power supply quick-connect connector, through a structure including a locking groove 5, mounting box 6, guide rod 7, pressure plate 8, locking block 9, pressing hole 10, first spring 11, and second spring 12, allows for quick and reliable connection of the female connector 1 and male connector 2. Pressing the pressure plate 8 through the pressing hole 10, guided by the guide rod 7, moves the pressure plate 8 into the mounting box 6, causing the locking block 9 to move inwards. Then, inserting the male connector 2 into the female connector 1 and releasing it, the pressure plate 8 and locking block 9 move outwards from the mounting box 6 under the action of the first spring 11 and second spring 12, causing the locking block 9 to engage with the locking groove 5, thus securing the male connector 2. Pressing the pressure plate 8 through the pressing hole 10 retracts the locking block 9, enabling initial locking of the connector after insertion into the female connector without external tools, resulting in a quick and more reliable connection.

[0038] 2. This emergency power supply quick-connect connector features a transition plate between the male connector 2, the female connector 1, and the connecting cable, which improves the bending resistance of the cable ends. The corners of the male connector 2 and the inner corners of the female connector 1 are rounded, making the connection between them smoother. The outer surface of the locking block 9 is beveled, allowing it to automatically move into the locking groove 5 under pressure. This ensures that the male connector 2 and female connector 1 can be connected even without pressing the pressure plate 8, further simplifying the connection process.
