[0040] Among related metal connectors, those with more features, such as waterproofing, have become bulky due to the increased functionality. This reduces aesthetic appeal during cable docking and occupies a large space, making them inconvenient for installation in small work environments. Other smaller metal connectors, however, have fewer features and are difficult to use in complex work environments.
[0041] See Figure 1 As shown, in order to improve the above problems, an embodiment of the present application provides a metal connector 100, which can be used for conductive connections between various devices or cables to maintain stable cable connections. At the same time, the overall structure is streamlined, the volume is small, and it is easy to install and use.
[0042] See also Figure 2 and Figure 3 As shown, the metal connector 100 includes a ferrule assembly 110, a connecting sleeve 120, and a locking member 130. The ferrule assembly 110 is used for conductive connection with an external connector. The connecting sleeve 120 is disposed outside the ferrule assembly 110 to protect the ferrule assembly 110. The locking member 130 locks onto the rear end of the connecting sleeve 120 to limit and fix the ferrule assembly 110.
[0043] Furthermore, the metal connector 100 provided in this application is a male connector, and therefore, the ferrule assembly 110 has a plurality of pins 112 that mate with the female jacks. The ferrule assembly 110 also includes an insulator 111 and a positioning ring 113. The insulator 111 has a plug end 1111 and has a plurality of through holes extending axially therethrough for mounting the pins 112. After each pin 112 is inserted into the corresponding through hole, the positioning ring 113 is sleeved on the end of the insulator 111 facing away from the plug end 1111 to limit the position of the insulator 111.
[0044] Specifically, insulator 111 can be made of PPS (Polyphenylene sulfide), which exhibits excellent thermal stability, wear resistance, creep resistance, excellent mechanical and electrical properties, low dielectric constant, and low dielectric loss. Pins 112 are made of a conductive metal material, such as copper or gold-plated material. The end of pin 112 facing away from the plug end 1111 of insulator 111 is conductively connected to the cable to achieve a conductive connection. In this way, the provision of insulator 111 secures each pin 112, ensuring stable insertion between the pin 112 and the female jack, allowing the pin 112 to connect to the female end via the plug end 1111 of insulator 111. At the same time, adjacent pins 112 are isolated from each other to prevent interference from current short circuits.
[0045] Both the positioning ring 113 and the connecting sleeve 120 are made of copper / nickel-plated material. The positioning ring 113 is placed on the side of the insulator 111 facing away from the plug end 1111 and restricts the rotation of the insulator 111 within the positioning ring 113, thereby limiting the movement of the insulator 111 and the pin 112, ensuring stable insertion of the pin 112. The connecting sleeve 120 is placed on the outside of the ferrule assembly 110 and covers both the insulator 111 and the positioning ring 113, securing and protecting the ferrule assembly 110 as a whole, preventing the wiring from tangling due to the rotation of the ferrule assembly 110.
[0046] Furthermore, the locking member 130 is passed through the connecting sleeve 120 and is threadedly engaged with the connecting sleeve 120 . When the locking member 130 and the connecting sleeve 120 are threadedly locked, the end of the locking member 130 presses against the positioning ring 113 .
[0047] Specifically, the inner side of the connecting sleeve 120 is provided with an internal thread, and the end of the locking member 130 connected to the connecting sleeve 120 is provided with an external thread, so that the locking member 130 can rotate relative to the connecting sleeve 120 to perform locking or separation operations, thereby realizing the rapid disassembly and assembly of the metal connector 100. At the same time, when the locking member 130 is locked to the connecting sleeve 120, the end surface of the locking member 130 located in the connecting sleeve 120 is pressed against the positioning ring 113 to fix the positioning and prevent the positioning ring 113 from moving in the axial direction. In this way, the metal connector 100 provided by the present application has a precise overall structure, and the size of each component can be set to be smaller, thereby reducing the volume of the metal connector 100 to be suitable for various application scenarios.
[0048] Continue reading Figure 4 and Figure 5 As shown, in some embodiments, a positioning key 1112 is provided on the circumferential side of the insulator 111 , and a positioning groove 1131 is correspondingly provided on the positioning ring 113 , and the positioning key 1112 is snap-fitted with the positioning groove 1131 .
[0049] Specifically, positioning groove 1131 is provided at one end of positioning ring 113 near insulator 111, and positioning groove 1131 extends through the body of positioning ring 113, forming a U-shaped notch. Positioning key 1112 is provided parallel to the axial direction of insulator 111, and its width is the same as the width of positioning groove 1131. Therefore, during the sleeve connection between insulator 111 and positioning ring 113, positioning key 1112 is inserted into positioning groove 1131 along the axial direction of insulator 111, completing the assembly of positioning ring 113 and insulator 111. Furthermore, the cooperation between positioning key 1112 and positioning groove 1131 prevents insulator 111 from rotating relative to positioning ring 113, ensuring the relative stability of each pin 112.
[0050] See again Figure 3 As shown, in some embodiments, the metal connector 100 further includes a shell 140 , which is sleeved on the outside of the connecting sleeve 120 .
[0051] Specifically, the housing 140 can be made of aluminum or nickel-plated material and is mounted on the end of the connecting sleeve 120 facing away from the locking member 130. When connected to an external female connector, the end of the housing 140 is inserted into the female connector interface, and the pins 112 are plugged into the female connector jack, thus achieving an electrical connection between the metal connector 100 and the external female connector. The housing 140 also seals the interior of the metal connector 100, ensuring a waterproof effect on the internal components.
[0052] Continue reading Figure 6 and Figure 7As shown, further, a locking hole 141 is opened on the peripheral side of the shell 140, and an elastic block is provided on the outer side of the connecting sleeve 120. The end of the elastic block is provided with a boss 122. When the shell 140 is sleeved on the connecting sleeve 120, the boss 122 is exposed and locked in the locking hole 141.
[0053] Specifically, the elastic block is arranged parallel to the axis of the connecting sleeve 120. When subjected to external force, one end of the elastic block can move toward the axis of the connecting sleeve 120. The locking hole 141 penetrates the surface of the shell 140. Therefore, during the assembly process of the shell 140 and the connecting sleeve 120, the boss 122 is squeezed by the inner wall of the shell 140, causing the elastic block 121 to gather toward the axis of the connecting sleeve 120, thereby not affecting the axial movement of the connecting sleeve 120 within the shell 140. When the boss 122 reaches the locking hole 141, the boss 122 is no longer squeezed by external force, the elastic piece returns to its original position, and the boss 122 protrudes from the locking hole 141. Under the restriction of the locking hole 141, the shell 140 and the connecting sleeve 120 are kept relatively fixed, completing the assembly of the shell 140 and the connecting sleeve 120.
[0054] Furthermore, a buckle 142 is further provided on the peripheral side of the shell 140 . The buckle 142 is located at an end of the shell 140 away from the connecting sleeve 120 and is used for plugging and positioning with the external metal connector 100 .
[0055] Specifically, multiple latches 142 may be provided, such as two, three, or four, depending on actual needs and not specifically limited herein. The latches 142 are arranged parallel to the axis of the housing 140 and protrude from the surface of the housing 140. When connected to an external female connector, the latches 142 engage with corresponding slots in the female connector, securing the housing 140 in place and ensuring a stable connection of the metal connector 100.
[0056] Continue reading Figure 8 As shown, in some embodiments, a plurality of protrusions 131 are provided on the outer side of the locking member 130 , and each protrusion 131 is circumferentially arranged along the axis of the locking member 130 to form a wave structure.
[0057] Specifically, locking member 130 can also be made of copper / nickel-plated material. The provision of raised portion 131 facilitates the user's application of force during assembly. Furthermore, during the conductive connection of metal connector 100, raised portion 131 can connect to the ground, achieving grounding and reducing the impact of earth electrical signals on the circuit.
[0058] Furthermore, a third sealing member 180 is provided on one end of the locking member 130 installed inside the connecting sleeve 120, so that when the locking member 130 and the connecting sleeve 120 are locked, the third sealing member 180 presses against the locking member 130 and the connecting sleeve 120 respectively, thereby realizing the sealing and waterproof function inside the metal connector 100.
[0059] Furthermore, the metal connector 100 further includes a shielding ring 150 . The shielding ring 150 is sleeved on an end of the locking member 130 away from the positioning ring 113 .
[0060] Specifically, shielding ring 150 can also be made of copper / nickel-plated material and coated with a frequency-blocking layer on its outer surface. The shielding ring 150 allows leakage current from the surface of electronic components to flow back to the power supply, protecting other devices or instruments from the effects of the leakage current and ensuring the circuit safety of metal connector 100.
[0061] Continue reading Figure 9 and Figure 10 As shown, in some embodiments, the metal connector 100 further includes a first seal 160, with stepped surfaces 161 formed on both the inner and outer sides of the first seal 160. The housing 140 is circumferentially defined with a first mounting groove 143, with abutment surfaces 144 formed on both sides of the first mounting groove 143. The first seal 160 is mounted in the first mounting groove 143, with each stepped surface 161 abutting against a corresponding abutment surface 144.
[0062] Specifically, the first seal 160 is a sealing ring structure, with stepped surfaces 161 provided on both the inner and outer sides to form an annular ring with a "convex" cross-section. After the first seal 160 is installed in the first mounting groove 143, the stepped surface 161 stretches and presses against the abutment surface 144 under the action of elastic potential energy to achieve surface sealing of the housing 140. Therefore, when the housing 140 is fitted with the external female end, the female end presses against the first mounting groove 143, and the first seal 160 is used to achieve external waterproofing when the metal connector 100 is connected to the female end. The overall structure is compact and the external dimensions are small, which can be adapted for use in scenes with even smaller spaces and has a wide range of uses.
[0063] Continue reading Figure 11 As shown, in some embodiments, the metal connector 100 further includes a second sealing member 170, and a second mounting groove is defined circumferentially within the connecting sleeve 120. One end of the second sealing member 170 is mounted within the second mounting groove, and an inclined portion 171 is defined on the end facing away from the second mounting groove. The inclined portion 171 expands in a direction away from the axis of the connecting sleeve 120, and the end thereof abuts against the housing 140.
[0064] Specifically, the second mounting groove is arranged at the connection between the connecting sleeve 120 and the end of the shell 140, and through the setting of the inclined portion 171, during the assembly process of the shell 140 without the connecting sleeve 120, the inclined portion 171 is pressed against the wall of the shell 140 under the action of elastic force, thereby realizing the waterproof sealing function at the connection between the connecting sleeve 120 and the shell 140, further improving the waterproof effect of the metal connector 100.
[0065] In summary, the metal connector 100 provided in the embodiment of the present application can meet the operating requirements in harsh environments and narrow spaces, has strong waterproof and vibration and impact resistance, facilitates the connectivity of pure electric, pure signal, electric and signal mixed systems, and has comprehensive performance of small size, light weight and high reliability.
[0066] An embodiment of the present application further provides an electrical device, comprising the metal connector 100 in any of the above embodiments.
[0067] This embodiment has the metal connector 100 in any of the above embodiments, and therefore has all the beneficial effects of the metal connector 100 in any of the above embodiments, which will not be described in detail here.
[0068] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0069] The above-described embodiments merely represent several implementation methods of the present application.
