Description

Technical Field

[0001] The present invention belongs to the technical field of grounding terminals, and in particular relates to a grounding terminal installation structure for electronic equipment. Background Art

[0002] In the field of electronic equipment, grounding is a crucial step in ensuring stable operation and user safety. From industrial control equipment to everyday consumer electronics, any electronic device can generate abnormal currents during operation due to internal circuit failures, static electricity accumulation, or external electromagnetic interference. Failure to promptly ground these currents can damage the device's delicate electronic components, shortening its lifespan and potentially posing a serious threat to the operator's safety.

[0003] During the operation of electronic equipment, good grounding is crucial to ensure the stable operation of the equipment and the safety of the users. As a key component connecting electronic equipment to the earth, the rationality of the installation structure of the grounding terminal directly affects the reliability of the grounding. Existing grounding terminal installation structures generally have some defects. For example, the installation process is complicated and requires professional tools and high operating skills, which not only increases the installation cost, but also easily leads to poor grounding due to improper installation. After long-term use, some installation structures are prone to loosening due to factors such as vibration and temperature changes, which greatly reduces the grounding effect. In addition, when maintaining or replacing the grounding terminal in the existing installation structure, it is often necessary to remove a large number of peripheral components, which is difficult, time-consuming and labor-intensive to operate.

[0004] Existing grounding terminal installation structures present numerous problems. Regarding the installation process, taking the common bolt-fastened installation structure as an example, it is necessary to first drill holes in the electronic device housing and the grounding terminal, and then assemble them using multiple components such as bolts, nuts, and gaskets. This process not only requires a variety of professional tools such as wrenches and screwdrivers, but also places extremely high demands on the installer's proficiency. According to relevant statistics, in a mass production environment, using traditional installation methods, it takes an average of approximately 15 minutes for each skilled worker to install a grounding terminal, which greatly reduces production efficiency and increases labor costs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a ground terminal installation structure for an electronic device that can overcome the above problems or at least partially solve the above problems.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a grounding terminal mounting structure of an electronic device, including a mounting seat, and also including: a grounding terminal plugged into the mounting seat, a clamping bolt slidably connected to the mounting seat, a pressing rod slidably connected to the clamping bolt, a clamping rod fixedly connected to the pressing rod, a clamping ball rollingly connected to the clamping bolt, a clamping hole opened on the clamping bolt, and the clamping hole corresponding to the clamping ball; a protective seat fixedly connected to the grounding terminal, a clamping seat fixedly connected to the mounting seat; The fixed connection is provided with a slot, and the protective seat is fixedly connected with an elastic claw; the grounding terminal is aligned with the mounting seat, so that the elastic claw is aligned with the mounting slot, and the grounding terminal is inserted into the mounting seat. The arc-shaped free end of the elastic claw is squeezed toward the inner wall of the slot. When the elastic claw moves to the slot position, the elastic claw bounces into the slot; by pressing the pressing rod, the pressing rod drives the clamping rod to move toward the inside of the grounding terminal. After releasing the pressing rod, the clamping ball on the clamping rod approaches the periphery of the grounding terminal, and the clamping ball is simultaneously clamped on the clamping bolt and the grounding terminal.

[0007] Furthermore, a threaded hole is provided on the grounding terminal for connecting the grounding wire. The threaded connector of the grounding wire is screwed into the threaded hole at one end of the grounding terminal body and tightened with a wrench to ensure that the wire is firmly connected to the grounding terminal body and has good contact to ensure conductivity.

[0008] Furthermore, a mounting hole is formed through the ground terminal.

[0009] Furthermore, a group of clamping bolts are provided at each end of the mounting seat, and a clamping hole is opened through the clamping bolt. The grounding terminal is aligned with the mounting seat, and the elastic claw is aligned with the mounting groove. The grounding terminal is inserted into the mounting seat. During the insertion process, the arc-shaped free end of the elastic claw is squeezed toward the inner wall of the groove and shrinks and deforms inward. When the elastic claw moves to the groove position, the elastic claw bounces into the groove. Due to the elastic restoring force, the claw bounces into the groove, and at the same time, the teeth on the inside of the claw engage with the teeth at the bottom of the groove to achieve preliminary fixation of the grounding terminal.

[0010] Furthermore, a tension spring is fixedly connected to the pressing rod, and one end of the pressing rod close to the pressing rod is opened into a trapezoidal shape.

[0011] Furthermore, a contact block is fixedly connected to the clamping rod, and the contact block is trapezoidal at one end close to the clamping rod. By pressing the clamping rod, the clamping rod drives the clamping rod to move toward the inside of the grounding terminal, driving the clamping ball out of the position of the clamping hole. After the clamping rod is released, the clamping rod returns to its previous position under the action of the tension spring, and the clamping rod drives the contact block to move toward the position of the clamping rod, while pushing the clamping ball toward the position of the clamping hole. The clamping ball is stuck between the clamping bolt and the grounding terminal to increase stability.

[0012] Furthermore, the diameter of the pressing hole is smaller than the diameter of the pressing ball.

[0013] Furthermore, the elastic claw is made of an elastic metal sheet, and the shape of the elastic claw is open to both ends and has an arc.

[0014] Furthermore, an elastic seat is fixedly connected to the protective seat, and an elastic claw is fixedly connected to the elastic seat.

[0015] Furthermore, a method for installing a ground terminal of an electronic device includes the following steps:

[0016] S1. Wire connection:

[0017] Screw the threaded connector of the grounding wire into the threaded hole at one end of the grounding terminal body and tighten it with a wrench to ensure that the wire is firmly connected to the grounding terminal body and has good contact to ensure conductivity.

[0018] S2. Install the grounding terminal:

[0019] Align the grounding terminal with the mounting seat, align the elastic claw with the mounting slot, and insert the grounding terminal into the mounting seat. During the insertion process, the arc-shaped free end of the elastic claw is squeezed against the inner wall of the slot and shrinks and deforms inward. When the elastic claw moves to the slot position, the elastic claw bounces into the slot. Due to the elastic restoring force, the claw bounces into the slot, and at the same time, the teeth on the inside of the claw engage with the teeth at the bottom of the slot to achieve preliminary fixation of the grounding terminal.

[0020] S3, tighten and fix:

[0021] By pressing the pressing rod, the pressing rod drives the clamping rod to move toward the inside of the grounding terminal, driving the clamping ball out of the position of the clamping hole. After releasing the pressing rod, the pressing rod returns to its previous position under the action of the tension spring, and the pressing rod drives the contact block to move toward the position of the pressing rod, while pushing the clamping ball toward the position of the clamping hole. The clamping ball is stuck between the clamping bolt and the grounding terminal to increase stability.

[0022] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: the grounding terminal of the present invention is aligned with the mounting seat, so that the elastic claw is aligned with the mounting slot, and the grounding terminal is inserted into the mounting seat. During the insertion process, the arc-shaped free end of the elastic claw is squeezed toward the inner wall of the slot and shrinks and deforms inward. When the elastic claw moves to the slot position, the elastic claw bounces into the slot. Due to the elastic restoring force, the claw bounces into the slot, and at the same time, the teeth on the inside of the claw engage with the teeth at the bottom of the slot to achieve preliminary fixation of the grounding terminal.

[0023] By pressing the pressing rod, the pressing rod drives the clamping rod to move toward the inside of the grounding terminal, driving the clamping ball out of the position of the clamping hole. After releasing the pressing rod, the pressing rod returns to its previous position under the action of the tension spring, and the pressing rod drives the contact block to move toward the position of the pressing rod, while pushing the clamping ball toward the position of the clamping hole. The clamping ball is stuck between the clamping bolt and the grounding terminal to increase stability. BRIEF DESCRIPTION OF THE DRAWINGS
