Abstract
Description
Technical Field
[0001] This disclosure relates to the field of auxiliary tool technology, and more particularly to a clamping tool. Background Technology
[0002] IPEX antennas serve as an interface between radio frequency (RF) circuits and antennas, and are widely used on the boards of wireless LAN (WLAN) related products. In laboratory noise testing, the antenna's IPEX connector terminals need to be connected to a spectrum analyzer to transmit all RF signals received by the antenna, including noise, to the spectrum analyzer. In factory production lines, when testing Voltage Standing Wave Ratio (VSWR), the antenna's IPEX connector terminals need to be connected to the spectrum analyzer's IPEX adapter. However, for protection of the antenna's IPEX connector terminals, the IPEX connector terminals are smaller than the IPEX adapter of the spectrum analyzer's RF extension cable. This can lead to the IPEX connector terminals easily detaching or making poor contact when connected to the spectrum analyzer's IPEX adapter.
[0003] There are two existing solutions to the above problem. One is to have one or two people hold the IPEX connection terminal and the spectrum analyzer IPEX adapter by hand to ensure good contact and prevent test abnormalities. However, this solution has high labor costs and low testing efficiency. The other solution is to use tape to stick the IPEX connection terminal and the spectrum analyzer IPEX adapter together. However, this solution has poor reliability and low operating efficiency. Utility Model Content
[0004] This disclosure provides a clamping tool to at least solve the above-mentioned technical problems existing in the prior art.
[0005] The clamping tool according to this disclosure includes:
[0006] The base has a clamping groove, which is configured to engage with the first piece to be clamped.
[0007] A clamping arm, rotatably connected to the base via a pivot, includes a clamping portion corresponding to the clamping groove, the clamping portion being used to abut against a second member to be clamped connected to the first member to be clamped; and
[0008] An elastic element is sleeved on the rotating shaft, and both ends of the elastic element are respectively connected to the base and the clamping arm;
[0009] The elastic element is capable of elastic deformation and has an initial state and a deformed state. When the elastic element is in the initial state, the clamping arm is located in a first position relative to the base.

[0018] In one embodiment, the base and the clamping arm are made of low-carbon chromium stainless steel.
[0019] In this disclosure, the clamping tool includes a base, a clamping arm, and an elastic element. It engages with the first clamping part through the clamping groove, and the clamping part abuts against the second clamping part. The deformation of the elastic element causes the clamping arm to rotate and press to fix the first clamping part and the second clamping part, thereby achieving a stable connection between the first clamping part and the second clamping part and improving the operating efficiency.

[0027] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0028] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.
[0029] Reference Figure 1 and Figure 3 As shown, this disclosure discloses an exemplary embodiment of a clamping tool, including a base 1, a clamping arm 2, and an elastic member 4. The base 1 has a clamping groove 11, which is configured to engage with a first clamping member 5. The clamping arm 2 is rotatably connected to the base 1 via a rotating shaft 3. The clamping arm 2 includes a clamping part 21, which corresponds to the clamping groove 11 and is used to abut against a second clamping member 6 connected to the first clamping member 5. The elastic member 4 is sleeved on the rotating shaft 3, and its two ends are respectively connected to the base 1 and the clamping arm 2. The elastic member 4 is capable of elastic deformation and has an initial state and a deformed state. When the elastic member 4 is in the initial state, the clamping arm 2 is located in a first position relative to the base 1. When the elastic member 4 is deformed by force, the clamping arm 2 rotates to a second position away from the base 1 to press and fix the first clamping member 5 and the second clamping member 6.
[0030] In this embodiment, the first clamping component 5 is typically an IPEX adapter for a spectrum analyzer, and the second clamping component 6 is an IPEX connector terminal. The base 1 is the foundation of the clamping tool, and can be made of metal or hard plastic. It has a clamping groove 11 for fixing the first clamping component 5. The clamping arm 2 is a movable part connected to the base 1 via a rotating shaft 3, and can be made of the same or similar material as the base 1. It includes a clamping part 21 for abutting against the second clamping component 6. The elastic element 4 provides elastic force, and can be made of a torsion spring, compression spring, or other elastic material. It is sleeved on the rotating shaft 3 and connects the base 1 and the clamping arm 2. Through the synergistic action of the base 1, the clamping arm 2, and the elastic element 4, stable fixation of the clamping component is achieved. The clamping groove 11 of the base 1 provides initial fixation, the rotatable design of the clamping arm 2 allows adjustment of the clamping position, and the elastic element 4 ensures a continuously controllable clamping force. This design not only accommodates clamping components of different sizes but also provides a stable and reliable clamping effect. In actual operation, the first clamping component 5 is first placed into the clamping groove 11 of the base 1. Then, the operator applies force to rotate the clamping arm 2. At this time, the elastic element 4 begins to deform. When the clamping arm 2 rotates to the appropriate position, the clamping part 21 abuts against the second clamping component 6. Due to the action of the elastic element 4, the clamping arm 2 continuously applies pressure to the clamping component, thereby achieving a stable clamping effect. This design is not only easy to operate, but also adaptable to connectors of different sizes, greatly improving the efficiency and reliability of RF testing. It is understood that the clamping tool disclosed herein can not only solve the problem of fixing IPEX connectors, but also has wide applicability and can be used for fixing other similar micro connectors.
[0031] The clamping tool of this application can be designed as follows: The base 1 is made of SUS430 ferritic stainless steel, with an overall length of 37mm, a width of 15.5mm, and a thickness of 5mm. A 6.5mm wide U-shaped clamping groove 11 is formed on the base 1 to accommodate the first clamped part 5. The clamping arm 2 is also made of SUS430 ferritic stainless steel, and the sides of the clamping arm 2 are folded at 90 degrees to increase the strength of the clamping arm 2. The clamping part 21 of the clamping arm 2 is located at its front end and is protected with a silicone pad to prevent damage to the second clamped part 6. When the operator applies force, the clamping part 21 can rotate to a position parallel to the base 1. At this time, the clamping part 21 can apply pressure to the second clamped part 6, which is sufficient to ensure the stability of the connection without damaging the connector.
[0032] In one embodiment, when the clamping arm 2 is in a second position relative to the base 1, the clamping part 21 and the base 1 satisfy the parallel condition.
[0033] In this embodiment, when the clamping arm 2 reaches the second position, the clamping part 21 remains parallel to the base 1. This parallel relationship allows the clamping part 21 to evenly press the second clamped part 6, firmly fixing it to the first clamped part 5. Due to the uniform pressure distribution, the risk of connector detachment or poor contact is greatly reduced. At the same time, the operator can easily determine whether the clamping is in place by observing the parallel relationship between the clamping part 21 and the base 1, without the need for additional inspection steps, thus improving operational efficiency. The clamping part 21 can be designed as a rectangular plate, with its length slightly larger than the diameter of the second clamped part 6. When the clamping arm 2 rotates to the second position, this rectangular plate will be parallel to the base 1, forming a stable clamping surface. An anti-slip textured layer or a soft material layer can be provided on the contact surface of the clamping part 21 to further enhance the clamping effect. For example, a layer of silicone can be coated on the surface of the clamping part 21, which can both increase friction and protect the second clamped part 6.
[0034] In one embodiment, the elastic element 4 is a torsion spring, with its two ends abutting against the base 1 and the clamping arm 2 respectively, so that the base 1 and the clamping arm 2 are held in a preset relative position when no external force is applied.
[0035] In this embodiment, the two ends of the torsion spring abut against the base 1 and the clamping arm 2, respectively. This design can be implemented in various ways. For example, one end of the torsion spring can be fixed in a groove on the base 1, and the other end can be inserted into a preset hole on the clamping arm 2. Alternatively, the two ends of the torsion spring can be connected to the base 1 and the clamping arm 2 respectively via a snap-fit structure. These different connection methods can be selected according to specific application scenarios and manufacturing processes. By using the torsion spring as the elastic element 4, and having its two ends abut against the base 1 and the clamping arm 2 respectively, the problem of the base 1 and the clamping arm 2 in the clamping tool remaining in a preset relative position when no external force is applied is effectively solved. The elastic characteristics of the torsion spring ensure the flexibility of the clamping tool during use, while also ensuring the stability of the tool when not in use. This design not only simplifies the structure of the clamping tool but also improves its efficiency and reliability. When the clamping tool is not in use, the torsion spring is in its natural state, and its elastic force keeps the base 1 and the clamping arm 2 in a preset relative position. This preset position can be that the clamping arm 2 and the base 1 are at a certain angle, such as 30°. When the clamping tool is needed, the user can apply external force to overcome the spring force of the torsion spring and rotate the clamping arm 2 to the desired position. Once the external force is removed, the restoring force of the torsion spring will cause the clamping arm 2 to automatically return to the preset position, thereby realizing the automatic reset function of the clamping tool.
[0036] In one embodiment, a first limiting portion 12 extends from the base 1 toward the clamping arm 2, and a second limiting portion 22 extends from the clamping arm 2 toward the base 1, with the first limiting portion 12 and the second limiting portion 22 corresponding to each other. When the clamping arm 2 is in a first position relative to the base 1, the first limiting portion 12 and the second limiting portion 22 abut against each other.
[0037] In this embodiment, the first limiting part 12 and the second limiting part 22 correspond to each other. When the clamping arm 2 is in the first position relative to the base 1, the two limiting parts abut against each other. This design can precisely control the position of the clamping arm 2 relative to the base 1, preventing the clamping arm 2 from rotating excessively. When the clamping arm 2 rotates relative to the base 1, the relative positions of the first limiting part 12 and the second limiting part 22 will change. For example, when the clamping arm 2 is in the first position, the two first limiting parts 12 and the second limiting part 22 abut against each other, forming a physical barrier to prevent the clamping arm 2 from continuing to rotate in one direction. It is understood that the first limiting part 12 and the second limiting part 22 can be made of elastic materials, such as rubber or elastic plastic. This design can provide a certain buffering effect while limiting the position, reducing the impact between the clamping arm 2 and the base 1, and extending the service life of the tool.
[0038] In one embodiment, the base 1 further includes a first hand-held portion 13, the clamping arm 2 further includes a second hand-held portion 23, and the rotating shaft 3 is located between the first hand-held portion 13 and the clamping groove 11, and between the second hand-held portion 23 and the clamping portion 21.
[0039] In this embodiment, the first handgrip 13 is disposed on the base 1, and the second handgrip 23 is disposed on the clamping arm 2. This design makes it easier for the user to grip and manipulate the clamping tool. The pivot 3 is located between the first handgrip 13 and the clamping groove 11, and simultaneously between the second handgrip 23 and the clamping part 21. This arrangement allows force to be transmitted more effectively to the clamping part 21 when pressure is applied. The first handgrip 13 and the second handgrip 23 can be designed in an ergonomic shape, such as a cylindrical shape or a grip with a non-slip texture. The pivot 3 can be made of a high-strength metal material to ensure its durability under frequent use. The clamping groove 11 and the clamping part 21 can be customized according to the shape of the object to be clamped, for example, they can be designed as V-shaped or U-shaped to accommodate objects of different shapes.
[0040] Reference Figure 2 As shown, in one embodiment, a protective layer 7 is provided on the first hand-held part 13 and the second hand-held part 23.
[0041] In this embodiment, the protective layer 7 effectively improves the grip of the handheld part and increases friction, thereby enhancing operational stability and safety. The protective layer 7 can be made of various materials and structures to achieve its function. For example, it can be made of rubber, silicone, or other materials with good elasticity and frictional properties. These materials not only provide a comfortable grip but also increase the friction between the hand and the tool, effectively preventing slippage during use. The surface of the protective layer 7 can be designed with a textured or uneven structure to further increase friction. For example, fine bumps or a mesh-like texture can be provided on the surface of the protective layer 7, which not only increases the contact area with the palm but also effectively wicks away sweat from the palm, maintaining a dry and comfortable grip.
[0042] In one embodiment, a flexible material layer 8 is provided on the clamping part 21 at the position where it contacts the second clamping member 6, for the purpose of protecting the second clamping member 6.
[0043] In this embodiment, by providing a flexible material layer 8 at the contact point between the clamping part 21 and the second clamping part 6, the problem of potential damage to the second clamping part 6 during clamping is effectively solved. The flexible material layer 8 can buffer the clamping force, reducing wear or indentations caused by direct contact, thereby protecting the surface integrity of the second clamping part 6. Simultaneously, the flexible material layer 8 can also increase friction, improving clamping stability. This design ensures both the effectiveness of clamping and avoids damage to the clamping part, improving the practicality and applicability of the clamping tool. The flexible material layer 8 can be provided in various ways. For example, the flexible material can be directly adhered to the clamping part 21, or an embedded design can be used, embedding the flexible material into a pre-reserved groove in the clamping part 21. The choice of flexible material can also be adjusted according to the specific application scenario; materials such as silicone, rubber, and soft plastic can be used. These materials have good elasticity and cushioning properties, effectively protecting the second clamping part 6.
[0044] In one embodiment, when the clamping arm 2 is in a first position relative to the base 1, an angle is formed between the second hand grip 23 and the first hand grip 13.
[0045] In this embodiment, by forming an angle between the second hand-holding portion 23 and the first hand-holding portion 13 in the first position, the operator's hand can be in a more natural and comfortable posture when holding the tool. This design takes into account ergonomic principles and helps reduce hand fatigue during prolonged use. This angle can be set between 15° and 45° to accommodate the natural grip posture of most users' hands. This angle design not only considers comfort but also takes into account the flexibility and precision of operation.
[0046] In one embodiment, the base 1 is a one-piece molded structure, and the clamping arm 2 is a one-piece molded structure.
[0047] In this embodiment, the manufacturing and assembly problems of the clamping tool are effectively solved by adopting a one-piece molded base 1 and clamping arm 2. This design simplifies the production process, reduces the number of parts, and improves the overall performance and reliability of the product. At the same time, the one-piece molded structure also helps to improve the durability and service life of the clamping tool, reducing the need for maintenance and replacement. Traditional multi-part assembly of the base 1 may require multiple processes, such as cutting, welding, and assembly, while the one-piece molded structure can be completed through a single process such as injection molding, die casting, or CNC machining, greatly reducing production costs and time.
[0048] In one embodiment, the base 1 and the clamping arm 2 are made of low-carbon chromium stainless steel.
[0049] In this embodiment, by selecting low-carbon chromium stainless steel as the material for the base 1 and the clamping arm 2, the clamping tool of this application can effectively solve problems such as corrosion, insufficient strength, easy breakage, and poor wear resistance that may be encountered during use. This material selection enables the clamping tool to adapt to various working environments and has better durability and reliability.
[0050] Furthermore, based on actual testing, the clamping tool disclosed herein has the following advantages:
[0051] 1. When testing VSWRs on the production line, it can reduce the manpower required for pressing connectors by two hands by one or two people, and improve testing efficiency, thereby increasing the proportion of VSWR tests. Specifically, before implementation, it took about 4 minutes to test a VSWR on the production line from wire connection to completion. After implementation, the testing time is about 2 minutes, an efficiency improvement of 100%.
[0052] 2. Ensure stable connector connections during testing in the R&D laboratory, reducing abnormal test results caused by unstable connections and improving testing efficiency. Specifically, before implementation, connecting terminals took approximately 3 minutes, including wire clamping in the R&D laboratory, tape fixing, and comprehensive evaluation of the time required to reconfirm test abnormalities caused by unstable fixing. After implementation, it takes approximately 1 minute, reducing the time spent on tape fixing and abnormal confirmation evaluation, resulting in a 200% efficiency improvement in this step.
