Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a quick-install connector. Background Art

[0002] A connector, also known as a plug-in connector, generally refers to an electrical connector, a device that connects two electronic devices and is used to transmit current or signals. Its function is to connect blocked or isolated circuits within a circuit. Connectors are indispensable components in electronic devices, and their form and structure vary greatly. There are various types of connectors depending on the application object, frequency, power, application environment, etc. Low-voltage electrical connectors are one of them. Due to their low application requirements, the installation process of low-voltage electrical connectors often requires the use of tools such as screwdrivers or wrenches, which is not only time-consuming but also increases installation costs.

[0003] To overcome these shortcomings, some connectors have emerged on the market that allow for quick, tool-free installation and removal. These connectors secure the wire terminals using spring compression or screw connections, allowing for quick assembly of the wire terminals within the body without the need for additional tools. However, these quick-install connectors suffer from complex structural designs, cumbersome operation, and high costs. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a quick-install connector to solve the problems of complex structural design, cumbersome operation and high cost.

[0005] The technical solution of the utility model is as follows: it includes an insulating body made of insulating material and a plug-in terminal, a plurality of mounting holes for inserting the plug-in terminals are provided in the insulating body, and the mounting holes pass through two opposite side surfaces of the insulating body; a buckle arm with elastic activity is provided on the insulating body, one end of the buckle arm is integrally connected with the insulating body, and the end of the other end has a protruding buckle head; the insulating body is provided with a buckle groove, the buckle groove is communicated with the mounting hole and the bottom of the buckle groove occupies a part of the space lateral to the mounting hole, the buckle groove and the buckle head are adapted to form a buckle connection, and the buckle head is tightly pressed on the plug-in terminal when buckled.

[0006] By adopting the above technical solution, the operator applies pressure on the buckle arm to buckle the buckle head into the buckle groove and fix the plug-in terminal in the mounting hole. In this way, the insertion and fixation of the plug-in terminal can be achieved through simple manual operation, which helps to improve the stability of the connection without the need for additional tools, facilitates processing and assembly, and makes the assembly process simpler and faster. In addition, the insulating body is integrally formed, which simplifies the main structure, reduces the number of parts, and reduces the cost of raw materials.

[0007] In one possible design, the buckle head includes a first inclined surface, a first abutting surface and a pressing surface, and a second protruding inclined surface and a second abutting surface are provided on the groove wall of the buckle groove. When the buckle head is buckled with the buckle groove, the first inclined surface and the second inclined surface contact each other and are staggered, and after staggering, the first abutting surface and the second abutting surface are in contact with each other, and the pressing surface is pressed tightly on the plug-in terminal.

[0008] With the above design, the first inclined surface and the second inclined surface act as a guide, and precise alignment is not required during installation, which reduces the difficulty of operation and facilitates the rapid installation of the buckle head. The first abutting surface and the second abutting surface abut against each other, forming a locking and fastening effect, making the connection between the buckle head and the buckle groove more secure, and can maintain a good fixed state even in the case of external vibration or impact, avoiding poor contact problems caused by looseness.

[0009] In a possible design, an observation hole is further provided on the insulating body, and the bottom of the observation hole is communicated with the mounting hole.

[0010] The above design allows the user to visually see through the hole whether the plug-in terminal is correctly inserted into the mounting hole, thereby improving installation accuracy and facilitating subsequent troubleshooting and maintenance.

[0011] In a possible design, an elastic snap arm is integrally connected to the insulating body.

[0012] With the above design, the elastic snap-fit arm is used to form a snap-fit connection with the corresponding connector, ensuring that the connection will not be easily loosened, thereby improving the reliability of the connector. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example 1: Figures 1 to 3 The illustrated quick-release connector includes an insulating body 1 made of insulating material and a plug-in terminal (not shown). The insulating body 1 defines two mounting holes 11 for inserting the plug-in terminal. These two mounting holes 11 extend along the height of the insulating body 1 along two opposing sides of the body for insertion. A resiliently movable snap-on arm 2 is provided on one side of the insulating body 1. One end of the snap-on arm 2 is integrally formed with the insulating body 1, and the other end has a protruding snap-on head 21. The snap-on arm 2 is elastic and deforms under external force, facilitating insertion and securing of the plug-in terminal. The insulating body 1 also defines a snap-on slot 12, which communicates with the mounting hole 11. The bottom of the snap-on slot 12 occupies a portion of the space lateral to the mounting hole 11. When the snap-on head 21 snaps into place with the snap-on slot 12, it presses against the plug-in terminal, ensuring that the plug-in terminal is securely secured within the mounting hole 11. The insulating body 1 is made of a plastic material with a certain elasticity and flexibility, which enables the buckle arm 2 to return to its original shape after being subjected to force. When the buckle arm 2 is not subjected to external force, the buckle head 21 is in a state of being out of the buckle groove 12. The external force presses the buckle arm 2 so that the buckle head 21 is located in the buckle groove 12. The buckle head 21 is tightly pressed against the plug-in terminal or forms a limit with the plug-in terminal, thereby fastening the plug-in terminal. When the plug-in terminal needs to be released, the connection between the buckle head 21 and the buckle groove 12 is released. The buckle head 21 is elastically disengaged from the buckle groove 12 and reset, and the plug-in terminal can be maintained or disassembled. The simple buckle arm 2 makes the overall structure of the connector simpler, reduces the number of parts, and reduces the difficulty of manufacturing. The user only needs simple operations to complete the insertion and fixation of the wire end without the use of additional tools, which greatly improves work efficiency.

[0022] In the structure of the insulating body 1, the buckle slot 12 extends from one side of the mounting hole 11 to the side of the insulating body 1, so that a portion of the buckle slot 12 is exposed in the width direction of the insulating body 1. Correspondingly, the buckle head 21 is adapted to the buckle slot 12 and also extends laterally to the side of the insulating body 1. Therefore, the buckle head 21 is partially or completely exposed in the width direction of the insulating body 1 even in the buckled state. This makes the buckle head 21 and the buckle slot 12 form a clearly visible and tangible structure on the side of the insulating body 1, which is convenient for operators to observe and operate, especially when disassembling.

[0023] The buckle head 21 includes a first inclined surface 211, a first abutting surface 212 and a pressing surface 213. The groove wall of the buckle groove 12 is provided with a protruding second inclined surface 121 and a second abutting surface 122. When the buckle head 21 forms a buckling connection with the buckle groove 12, the first inclined surface 211 and the second inclined surface 121 first contact each other and stagger. In the process of the inclined surfaces staggering each other, the first inclined surface 211 moves inward along the second inclined surface 121 until the first inclined surface 211 completely crosses the second inclined surface 121. At this time, the first abutting surface 212 and the second abutting surface 122 abut against each other to form a stable buckling state. The pressing surface 213 is located on the other side of the buckle head 21. When the buckle head 21 is completely buckled into the buckle groove 12, the pressing surface 213 will be pressed on the plug-in terminal to ensure that the plug-in terminal can be firmly fixed in the mounting hole 11. The above structure utilizes the guiding effect of the inclined surface to enable the buckle head 21 to smoothly enter the buckle groove 12 and form a locking and fastening effect through the interaction of the abutting surfaces.

[0024] The insulating body 1 is also provided with an observation hole 13, the bottom of which communicates with the corresponding mounting hole 11. This allows the user to visually check whether the plug-in terminal is correctly inserted into the mounting hole 11. If a problem occurs with the connector during subsequent use, the observation hole 13 allows maintenance personnel to quickly check the internal condition of the connector and determine whether any wire terminals are loose or falling off, allowing timely repair measures to be taken.

[0025] An elastic snap arm 3 is integrally connected to the insulating body 1, and the elastic snap arm 3 is used to form a snap connection with the corresponding connector. The elastic snap arm 3 has a certain elastic deformation ability. When not subject to external force, the elastic snap arm 3 is in a naturally extended state and can connect with the slot on the corresponding connector.

[0026] Example 2: Figure 4 、 Figure 5 As shown, unlike the above-mentioned embodiment, six mounting holes 11 are defined within the insulating body 1, and buckle slots 12 are defined on two opposing side surfaces of the insulating body 1. Each buckle slot 12 communicates with three corresponding mounting holes 11. Accordingly, two buckle arms 2 are integrally connected to the insulating body 1, each having a corresponding buckle head 21. An operator can clamp and press the two buckle arms 2 toward each other, causing the buckle heads 21 to engage with the corresponding buckle slots 12, thereby securing the plug terminal.
