[0002] In electronics and electrical engineering, terminals usually refer to joint components used to connect wires or cables. They can achieve the conduction of electrical signals or currents, and common types include single-hole, double-hole, socket, hook, flag-shaped, blade-shaped, etc. Among them, the flag-shaped terminal (also called the flag-type terminal) is a common electrical connection terminal, usually used for electrical contact between wires, conductors and equipment. Its name comes from its shape, like a flag, and both ends of the terminal often present a rectangular or flag-like shape.

[0003] Protection is one of the key designs of the flag-type terminal. It not only ensures electrical safety (such as preventing short circuits, insulation, and avoiding electric shock), but also improves the durability of the terminal and its working performance in harsh environments. Therefore, the protective layer of the flag-type terminal is crucial for the stability and safety of the equipment. Existing flag-shaped terminal protection devices often use soft rubber materials.

[0044] The following is a detailed description of the specific implementation mode of the present invention, but it should be understood that the protection scope of the present invention is not limited by the specific implementation mode.

[0045] As Figures 5 - 10 shown, an insulating sheath of a flag-shaped terminal provided by an embodiment of the present invention includes a front-end protective shell 1 and a rear-end protective shell 2, and the rear-end protective shell 2 is openable and closable for installing the flag-shaped terminal. During remanufacturing, the front-end protective shell 1 and the rear-end protective shell 2 are integrally injection molded.

[0046] The rear-end protective shell 2 is provided with a left half protective shell 22 and a right half protective shell 23, and the left half protective shell 22 and the right half protective shell 23 can be rotated to enable the flag-shaped terminal to achieve at least two states.

[0047] In the first state, the left half protective shell 22 and the right half protective shell 23 are located on opposite sides of the upper part of the front-end protective shell 1.

[0048] In the second state, the left half protective shell 22 and the right half protective shell 23 are butted and assembled with each other and clamped and fixed, so that the flag-shaped terminal is located in the enclosed space formed by the front-end protective shell 1, the left half protective shell 22, and the right half protective shell 23.

[0049] Specifically, a front cavity 11 is provided inside the front protective shell 1, and the front cavity 11 is used for positioning the flag-shaped terminal. A rear cavity 21 communicating with the front cavity 11 is provided inside the rear protective shell 2, and the rear cavity 21 is used for insulating the wire-wrapping part of the terminal. In the second state, the left half protective shell 22 and the right half protective shell 23 are respectively rotatably connected to opposite sides of the upper part of the front protective shell 1. After the left half protective shell 22 and the right half protective shell 23 are docked and assembled with each other and fixed by buckles, a wire outlet hole 24 is formed, and the wire outlet hole 24 communicates with the rear cavity 21. The left half protective shell 22 and the right half protective shell 23 can be docked and assembled with each other and fixed by buckles, which can facilitate quick assembly, achieve wrapped full insulation for the flag-shaped terminal, and improve the protection effect.

[0050] Wherein, one end of the left half protective shell 22 extends outward with a left half ring plate 221, one end of the right half protective shell 23 extends outward with a right half ring plate 231, the wire outlet hole 24 is formed by splicing the left half ring plate 221 and the right half ring plate 231, and the wire outlet hole 24 communicates with the rear cavity 21.

[0051] A reduced-diameter section 12 is further provided on the upper part of the front protective shell 1. A stepped portion 121 is formed between the reduced-diameter section 12 and the lower part of the front protective shell 1. The left half protective shell 22 and the right half protective shell 23 are respectively connected to the stepped portions 121 on opposite sides of the reduced-diameter section 12. After the left half protective shell 22 and the right half protective shell 23 are assembled, the reduced-diameter section 12 is wrapped in the rear cavity 21.

[0052] Reinforcing ribs 25 are provided on the outer sides of the connection between the left half protective shell 22 and the front protective shell 1 and the connection between the right half protective shell 23 and the front protective shell 1. A plurality of reinforcing ribs 25 are provided, and the plurality of reinforcing ribs 25 are spaced apart at the connection to increase the radial tensile force between the left half protective shell 22 and the front protective shell 1 and between the right half protective shell 23 and the front protective shell 1, reduce the occurrence of fracture of the rotatable connection section of the left half protective shell 22 and the right half protective shell 23, and improve the overall strength and service life of the insulating sheath.

[0053] The rear protective shell 2 is provided with a clamping structure, and the left half protective shell 22 and the right half protective shell 23 are clamped and connected through the clamping structure. The clamping structure includes a clamping hole 26 and a clamping hook 27. Two clamping holes 26 are spaced apart on one end side of the port of the left half protective shell 22 away from the front protective shell 1, and two clamping hooks 27 are provided on one side of the port of the right half protective shell 23 away from the front protective shell 1. The clamping hooks 27 and the clamping holes 26 correspond to each other and are clamped and connected.

[0054] Wherein, one end edge of the clamping hole 26 extending away from the front protective shell 1 extends outward with a reinforcing piece 261, and a guiding inclined surface 262 is provided on the inner side of the end of the reinforcing piece 261 to guide the clamping hook 27 into the clamping hole 26. A retaining convex rib 271 is provided on the inner side of the end of the clamping hook 27 to further reduce the occurrence of the separation of the clamping hook 27 and the clamping hole 26 and improve the product stability.

[0055] In other embodiments, a snap hook may also be provided on the left half protective case 22, and a snap hole may be provided on the right half protective case 23. The snap hook and the snap hole are respectively provided on the left half protective case and the right half protective case and can realize the snap connection between the left half protective case and the right half protective case.

[0056] An inner step positioning plate 28 extends upward along the outer edge of the inner cavity of the left half protective case 22. When the left half protective case 22 and the right half protective case 23 are butted and snapped together, the outer wall surface of the inner step positioning plate 28 fits against the inner wall surface of the right half protective case 23. The inner step positioning plate 28 is provided for positioning the butting position of the left half protective case 22 and the right half protective case 23, reducing the occurrence of misalignment and opening / closing at the connection after butting and snapping, improving the structural stability, and playing a sealing role in the butting gap thereof, reducing the possibility of dust and other impurities entering the insulating cover, and playing a protective role.

[0057] A limiting structure is provided in the front cavity 11 for restricting the position of the flag-shaped terminal. The limiting structure includes a pressing block 111, a limiting block 112, and a first limiting groove 114.

[0058] Specifically, pressing blocks 111 and limiting blocks 112 are respectively provided on the inner side walls at both ends where the port of the front cavity 11 is connected to the rear end protective case 2 to limit the position of the flag-shaped terminal in the front cavity 11. The pressing block 111 is provided in the middle of the side wall of the front cavity 11. The limiting blocks 112 are provided as a group, and a group of limiting blocks 112 are respectively provided at both ends of the side wall of the front cavity 11, and a convex-shaped through hole is formed in the front cavity 11. The pressing block 111 and the limiting block 112 are used for laterally positioning the flag-shaped terminal to reduce its shaking. A supporting structure is provided on the lower wall of the port of the front cavity 11 for supporting the bent portion at the bottom of the flag-shaped terminal. The supporting structure includes, but is not limited to, a block structure, a plate structure, and a strip structure. In this embodiment, the supporting structure is a supporting convex block 113, and the supporting convex block 113 is provided at the edge of one end of the limiting block 112 facing the pressing block 111. First limiting grooves 114 are provided on both sides of the port of the front cavity 11. The supporting convex block 113 is used for supporting the bent portion at the bottom of the flag-shaped terminal to achieve the effect of full insulation, and the first limiting grooves 114 are used for restricting the position of the wiring end of the flag-shaped terminal to prevent the terminal from falling off.

[0059] In one embodiment, as Figures 11 - 12 shown, the difference from the above embodiment is that the insulating sheath in this embodiment is matched with a self-locking flag-shaped terminal, and the positioning structure inside the front cavity 11 is different: a connecting block 3 is fixedly connected to the inner wall of the front cavity 11. The connecting block 3 is used for being snapped with the flag-shaped terminal during the installation of the flag-shaped terminal to realize the self-locking state of the flag-shaped terminal. The self-locking flag-shaped terminal is assembled in the front cavity 11 and is self-locked with the connecting block 3, solving the problem of low production efficiency caused by manual installation in the prior art and achieving the production effect of automatic assembly.

[0060] In another embodiment, asFigures 1 - 10 , Figure 13 As shown in Figure 13 , a detection method for an insulating sheath of a flag-shaped terminal is provided, including:

[0061] First, screen out qualified flag-shaped terminal products and compatible inserts, and then assemble the flag-shaped terminal, the insert, and the insulating sheath.

[0062] Specifically, first visually inspect the surface of the flag-shaped terminal product to ensure that there are no bubbles, obvious deformations, or damage marks on the product surface, and there is no rust, obvious oxidation, or obvious mechanical damage defects on the surface of the plug spring and the insert. The insulating sheath should fit well with the plug spring (not shown in the figure), not be easily detached, and the metal body of the plug spring should be exposed after being matched with the insulating sheath. Then connect the flag-shaped terminal and the insert to ensure a firm electrical connection between the two, and fix the insulating sheath to the flag-shaped terminal to ensure good insulation, which is convenient for subsequent quality inspection, electrical testing, and mechanical testing.

[0063] Connect the circuit for electrical performance detection and measure the resistance value. In this step, a resistance sorting instrument can be used to test the contact resistance between the flag-shaped terminal and the insert, and the contact resistance needs to be less than or equal to 0.01 Ω. Between the outer shell of the insulating sheath and the flag-shaped terminal, an insulating resistance test is carried out using a 500V DC circuit, and the insulating resistance needs to be greater than or equal to 100 MΩ.

[0064] Mechanical performance detection also needs to be carried out based on the measurement of the insertion and extraction force.

[0065] Specifically, fix the insert on an external force measuring device, and slowly and smoothly insert and extract the socket into and out of the insert multiple times at a rate of 1 mm / s. In this embodiment, insert and extract 6 times. During the test, the insertion force is the largest, which is 7.75 kgf. That is, the maximum extraction force for the first time is 7.75 kgf, the minimum is 0.13 kgf, and the minimum extraction force for the sixth time is 0.13 kgf.

[0066] Furthermore, environmental adaptability detection is carried out through salt spray test, temperature test, and rapid temperature change.

[0067] In the salt spray test, a sodium chloride solution with a concentration of (5 ± 0.1)% (mass percentage) is used, and it is continuously sprayed for 24 h. After the test, wash off the surface deposits and restore for 1 h to 2 h under normal temperature and constant humidity conditions. There should be no damage to the appearance, and there should be no serious rust exposing the base metal on the hardware, and the measured contact resistance should not be greater than 0.02 Ω.

[0068] In the temperature test, the test temperature is 125°C ± 2°C, and the test time is 24 h. After the temperature test, it is required to meet the condition that there is no damage affecting normal operation.

[0069] In the rapid temperature change test, expose it at -25°C for 3 minutes, +85°C for 3 minutes, and cycle 5 times with a conversion time less than 3 minutes in the middle. After the experiment, place it under normal conditions to recover for 2 hours. After the test, there should be no damage affecting normal operation. The measured contact resistance should not be greater than 0.02 Ω, and the measured insulation resistance should be greater than 500 MΩ.

[0070] In this application, safety performance testing also needs to be carried out through the needle flame test and the glow wire test, and environmental compliance testing is carried out based on industry standards.

[0071] In environmental compliance testing, ROHS refers to the "Directive on the Restriction of the Use of Certain Hazardous Substances" or the Hazardous Substances Restriction Directive. It is an environmental protection regulation introduced by the European Union in 2003, aiming to restrict the use of certain hazardous substances in electronic and electrical equipment. If these substances are used in the equipment and not properly treated, they may pose hazards to the environment and human health. In this embodiment, it is necessary to detect according to the IEC62321 standard method, and the contents of lead, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated polyphenylene ethers detected are all less than 1000 ppm, and the chromium content is less than 100 ppm.

[0072] In the needle flame test, the flame height is 12 mm ± 1 mm, the flame is placed at about 45°, and the sheath is placed vertically. For the actual used components of the sheath, strip the wire skin, together with the sheath, metal wire, and terminal. After applying the needle flame for 15 s, it should meet one of the following conditions:

[0073] a) The test sample has no flame and glow, and the specified bottom layer or packaging tissue paper does not catch fire.

[0074] b) After removing the needle flame, the flame or glow of the test sample and the surrounding components extinguishes within 5 s, and the surrounding components are not completely burned and the specified bottom layer or packaging tissue paper does not catch fire.

[0075] In the glow wire test, the test needs to be carried out according to the following methods and requirements.

[0076] a) The test temperature of the insulating material supporting or fixing the current-carrying component is 750°C ± 10°C, and the test duration is 30 s ± 1 s. The test method is carried out according to the provisions of GB / T 5169.11. If the test sample does not burn or glow, or the flame duration generated during the test period (referring to the period when the glow wire is applied and after the glow wire is removed) does not exceed 2 s, it is considered to have passed this glow wire test.

[0077] b) The test temperature of the insulating material supporting or fixing the current-carrying component is 850°C ± 15°C, and the test duration is 30 s ± 1 s. The test method is carried out according to the provisions of GB / T 5169.11. If the test sample does not burn or glow, or all meet the following conditions, it is considered to have passed this glow wire test:

[0078] 1) If the flame or glow of the test specimen extinguishes within 30 s after removal of the glow wire, i.e., te ≤ ta + 30 s; and

[0079] 2) When using the specified bottom layer of packaging tissue paper, the tissue paper shall not catch fire.

[0080] Wherein, ta refers to the time of applying the glow wire, and te refers to the duration from the start of applying at the top of the glow wire to the extinguishment of the flame.

[0081] The above discloses only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art shall fall within the protection scope of the present invention.
