Abstract
Description
Technical Field
[0001] This utility model relates to the field of adapter technology, specifically to an adapter with stable contact. Background Technology
[0002] In the core of electronic device connectivity and power transmission, connection reliability directly determines system performance. Contact-stable adapters are specialized components designed to address this critical issue. Going beyond simple connectivity, they offer a secure, efficient, durable, and uninterrupted connection solution. Whether powering critical data center servers, connecting high-precision medical instruments, or everyday fast-charging devices, they are an indispensable cornerstone for ensuring stable system operation and protecting device safety. However, existing contact-stable adapters still have certain shortcomings. While traditional adapters with stable contact can be used effectively, traditional connectors are prone to loosening or even complete disconnection when subjected to cable pulling, equipment vibration, or minor impacts. This can lead to signal interruption and power loss, making them highly unreliable in mobile or vibrating environments. Simple snap-fit connectors are also susceptible to wear and tear, and may fail due to aging. Furthermore, the metal contacts of traditional connectors typically rely on their own elasticity to generate contact pressure. With prolonged insertion and removal, and under high temperatures, the metal undergoes fatigue and stress relaxation, resulting in reduced elasticity, decreased contact pressure, and increased contact resistance. This can cause risks such as decreased power supply voltage, data signal attenuation, and connector overheating, frequently troubling users. Utility Model Content

[0014] Please see Figure 1-4 This utility model provides a technical solution, an adapter with stable contact, including a main connector 1, a secondary connector 2 and a clamping mechanism 3. The main connector 1 and the secondary connector 2 are of insert type design. The clamping mechanism 3 is provided on the main connector 1. The main connector 1 includes a main cable 101, a first housing 102, contact pins 103, a limiting block 104 and a first outer shell 105. The clamping mechanism 3 includes a fixed block 301, a first fixed shell 302, a rack 303, a buffer pad 304, a gear 305, a drive shaft 306, a turntable 307, and a second fixed shell 308. The fixed block 301 is fixedly installed on the upper top surface of the first shell 105. The first fixed shell 302 is rotatably connected to the fixed block 301. The rack 303 is slidably connected inside the first fixed shell 302. The buffer pad 304 is fixedly installed on the left side of the rack 303. The gear 305 meshes on the rack 303. The drive shaft 306 is fixedly installed on the gear 305, and the turntable 307 is fixedly installed on the other end of the drive shaft 306.
[0015] A second fixed housing 308 is fixedly installed on the top of the first fixed housing 302, and the second fixed housing 308 is connected to the transmission shaft 306 by a bearing.
[0016] A first housing 102 is fixedly installed at the left end of the main cable 101. A contact pin 103 is provided inside the first housing 102. The contact pin 103 is fixedly installed with the first housing 102. A limit block 104 is fixedly installed on the right side of the inner wall of the contact pin 103. A first outer shell 105 is fixedly installed on the outer wall of the first housing 102.
[0017] The secondary connector 2 includes a secondary cable 201, a second housing 202, an insertion pin 203, a spring 204, and a second outer shell 205. The second housing 202 is fixedly installed on the right end of the secondary cable 201, and the insertion pin 203 is provided inside the second housing 202.
[0018] A spring 204 is sleeved on the right end of the insertion pin 203, and the spring 204 and the insertion pin 203 are fixedly installed. A second outer shell 205 is fixedly installed on the outside of the second housing 202.
[0019] The spring 204 abuts against the left wall of the limiting block 104, and the insertion pin 203 is inserted into the inside of the contact pin 103. The second housing 202 is inserted into the inside of the first housing 102, and the second outer shell 205 is inserted into the inside of the first outer shell 105.
[0020] Working Principle: When using a stable contact adapter, the user first aligns the insertion pin 203 of the secondary connector 2 with the contact pin 103 of the primary connector 1 and inserts it. The second housing 202 then enters the first housing 102, and the second outer shell 205 enters the first outer shell 105. During insertion, the insertion pin 203 of the secondary connector 2 compresses the externally sleeved spring 204. Once fully inserted, the right side of the spring 204 abuts against the left wall of the limiting block 104 inside the primary connector 1. At this time, the compressed spring 204 generates a continuous reverse elastic force, which tends to push the entire secondary connector 2 towards the right. However, this tendency is blocked by the limiting block 104, thus transforming into a tight and stable positive contact pressure between the insertion pin 203 and the contact pin 103. This flexible design compensates for manufacturing tolerances and wear, ensuring the reliability of the electrical connection. After initial insertion, the user manually rotates the turntable 307 of the clamping mechanism 3. The rotation of the turntable 307 drives the transmission shaft 306 to rotate, which in turn drives the gear 305 fixed thereto to rotate. The gear 305 meshes with the rack 303, converting the rotational motion of the gear 305 into the horizontal linear motion of the rack 303. The rack 303 moves to the left, pushing the buffer pad 304 installed at its left end to move to the left in sync. The buffer pad 304 then presses tightly against the end face of the second housing 205 of the inserted sub-connector 2. By rotating the turntable 307, the user can control the pressure applied by the buffer pad 304, thereby physically locking the sub-connector 2 firmly and effectively resisting external pulling forces, vibrations, and other factors that could cause loosening. The buffer pad 304 is made of flexible materials such as rubber or silicone, which provides sufficient friction while avoiding scratches on the surface of the sub-connector 2, thus completing a series of operations. The contents not described in detail in this specification are prior art known to those skilled in the art.
