AI Technical Summary
The design of traditional female terminals is ineffective due to the loss of elasticity of the shrapnel in a long-term high vibration environment, causing contact failure, and the current and signal cannot be transmitted normally.
The design includes main shrapnel, secondary shrapnel and reverse flap. The main shrapnel is in contact with the secondary shrapnel. The reverse flap protects the main shrapnel. The inner concave and bumps and bumps contact positions are combined with the flap structure to ensure contact stability in a high vibration environment. , and prevent damage when inserting non-parallel through reinforcement of the trace.
It effectively reduces the amplitude of the shrapnel and provides a support mechanism to ensure that the signal and power transmission is not interrupted, and prevents the main shrapnel from deforming and ensures uninterrupted contact.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of female terminals and relates to a female terminal that prevents vibration failure. Background Art
[0002] Connectors are electro-thermo-mechanical devices that allow for detachable connections to transmit power and electrical signals. Signals or electrical power are transmitted through metal conductors, while plastic housings are used in connectors to isolate the metal conductors from each other. Plastic housings are also used to align the conductors and ensure that the conductors are securely locked to the insulator.
[0003] The metal conductors of the connector are divided into male terminals and female terminals (see Figure 4 ), the male terminal is basically a simple column design, and the female terminal is more complex in design. Its main purpose is to clamp the male terminal to ensure good contact even in different environments. The area where the traditional female terminal clamps the male terminal is designed to be similar to a bell mouth (see Figure 4 ), the bell mouth has a large entrance and then gradually becomes smaller, and then gradually becomes larger. The contact between the male terminal and the female terminal is in this narrowest area (see Figure 4 ). The bell-shaped area where the conventional female terminal and the male terminal contact can be a bell-shaped area formed by a piece of spring and a bump or two pieces of spring.
[0004] This type of design with a spring sheet and a bump or two spring sheets forming a traditional bell-shaped female terminal will lose its original elasticity in a long-term high-vibration environment because the spring sheet experiences continuous high-amplitude vibration and reaches a critical state, eventually causing contact failure and inability to transmit current and signals normally. Summary of the invention
[0005] The purpose of the utility model is to provide a female terminal that prevents vibration failure, so as to solve the problems raised in the above background technology.
[0006] The purpose of the utility model can be achieved through the following technical solutions: an anti-vibration failure female terminal, comprising a female terminal body, a main spring piece and a secondary spring piece, a spring piece connecting seat is arranged inside the female terminal body, the main spring piece and the secondary spring piece are both arranged at one end of the spring piece connecting seat and the main spring piece and the secondary spring piece are in contact and connected, the bending portion of the main spring piece corresponds to a folded piece connected to the female terminal body, the outer surface of the female terminal body is provided with inner concave and convex points, the inner side of the inner concave and convex points is provided with a convex contact position corresponding to the main spring piece, and a bell mouth is arranged between the convex contact position and the main spring piece.
[0007] In the above-mentioned vibration-failure-proof female terminal, a terminal connection housing is provided at one end of the female terminal body, and a clamping portion is provided at one end of the terminal connection housing.
[0008] In the above-mentioned vibration-failure-proof female terminal, the outer surface of the terminal connection housing is provided with reinforcement lines.
[0009] Compared with the prior art, the advantages of the vibration-proof female terminal of the utility model are as follows: by providing the main spring sheet, the secondary spring sheet and the inverted sheet, not only the amplitude of the spring sheet of the traditional female terminal in a high vibration environment is reduced, but also a backup is provided for the main spring sheet that fails in a very small probability, ensuring uninterrupted contact and normal transmission of signals and power. The design of the inverted sheet ensures that even when the male terminal is not inserted in parallel, the spring sheet of the female terminal will not be damaged. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0016] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model anti-vibration failure female terminal includes a female terminal body 1, a main spring piece 6 and a secondary spring piece 7, a spring piece connecting seat 8 is arranged inside the female terminal body 1, the main spring piece 6 and the secondary spring piece 7 are both arranged at one end of the spring piece connecting seat 8 and the main spring piece 6 and the secondary spring piece 7 are contacted and connected, the bending portion of the main spring piece 6 corresponds to a reversed piece 9 connected to the female terminal body 1, the outer surface of the female terminal body 1 is provided with inner concave and convex points 4, the inner side of the inner concave and convex points 4 is provided with convex contact positions 5 corresponding to the main spring piece 6, and a bell mouth 10 is provided between the convex contact position 5 and the main spring piece 6.
[0017] In this embodiment, a terminal connection housing 2 is provided at one end of the female terminal body 1, and a clamping portion 3 is provided at one end of the terminal connection housing 2. The outer surface of the terminal connection housing 2 is provided with reinforcement lines.
[0018] Working principle: The female terminal body 1 of the utility model adopts a design of an inner concave-convex point 4 and a main spring piece 6, and another secondary spring piece 7 is added behind the main spring piece 6 (see Figure 2 ). This additional secondary spring clip 7 can be close to the main spring clip 6 or at a small distance. The function of the main spring clip 6 is the same as that of the traditional female terminal spring clip. In order to provide the required elasticity and positive force, it is ensured that when the male pin is inserted into the female terminal, the main spring clip has enough elasticity to move the spring clip, allowing the male pin to be inserted into the female terminal without hindrance, and at the same time provide the correct positive force to ensure the flow of current. The secondary spring clip 7 and the main spring clip 6 maintain an optimal close distance to ensure that the amplitude of the main spring clip 7 is controlled within an acceptable range in a high-vibration environment. In the extremely small probability that the main spring clip 7 loses its elasticity, the secondary spring clip 6 becomes a backup to ensure that the signal and power can flow normally.
[0019] In order to ensure that the main spring piece 7 will not be deformed when the male terminal is inserted into the female terminal at an angle, a folded piece 9 is provided at the entrance of the female terminal on the same side as the main spring piece 7. The folded piece 9 protects the front end of the main spring piece 6 to ensure that even if the male terminal is inserted into the female terminal at an angle, it will not hit the front end of the main spring piece 6 and cause the main spring piece 6 to deform.
