AI Technical Summary
In the existing female terminal structure, when the male terminal is inserted at an angle, the spring is easily deformed, resulting in contact failure, affecting the reliability of the circuit connection, especially prone to false connection or circuit breakage during vehicle vibration.
A female terminal structure is designed, including an insertion channel, a spring sheet, a protrusion and a support sheet. By setting the support sheet to be bent integrally with the base plate, the support of the spring sheet is increased to prevent excessive deformation of the spring sheet. An upward arch is set in the middle of the spring sheet to enhance the contact force. Combined with the first and second protrusions, the spring sheet is protected to ensure that excessive squeezing does not occur when the male terminal is inserted.
Improves the vibration resistance of female terminals, prevents contact failure due to tilted insertion, reduces material costs by 7%, and reduces shipping costs.

Abstract
Description
Technical Field
[0001] The present application belongs to the field of terminal structures, and specifically relates to a female terminal structure. Background Art
[0002] A large number of terminal plug-in structures are required in the electrical structure of automobiles. When the terminals are used, the male PIN may be inserted into the female terminal at an angle. When inserted at an angle, the spring inside the female terminal will be severely deformed and unable to return to its original state, resulting in contact failure, and then causing circuit disconnection or even circuit breakage, with serious consequences.
[0003] See attached Figure 5 The figure shows an existing structure 3 of a female terminal. The spring clip is tilted upward and its length is the same as the insertion channel. When used, the male terminal 2 is inserted at an angle into the female terminal with the existing structure, which will forcibly flatten the spring clip inside the female terminal. The spring clip's excessive deformation causes the material to yield, ultimately weakening its rebound force and failing to provide sufficient pressure on the male terminal (referred to as the "flat PIN" problem). When the vehicle vibrates during driving, the contact point will become loose, affecting the normal use of the vehicle. Utility Model Content
[0004] In order to solve the above problems, the utility model proposes a female terminal structure.
[0005] The utility model solves the technical problem by adopting the following technical solutions:
[0006] A female terminal structure includes a plug-in channel, a spring piece, a protrusion and a support piece. The plug-in channel and the tail wing are coaxially arranged and made into one piece. The plug-in channel is a square channel composed of a bottom plate, side plates on both sides and a top plate. An integral spring piece is provided on the bottom plate in the plug-in channel. The spring piece is arranged upwardly and tilted from the socket of the plug-in channel toward the tail wing. First protrusions are symmetrically arranged in the middle of the side walls on both sides below the spring piece. A support piece is provided on the bottom plate corresponding to the bottom below the free end of the spring piece in the plug-in channel.
[0007] Moreover, a second protrusion is provided on the side wall between the first protrusion and the inlet end.
[0008] Moreover, the support sheet is made integrally with the bottom plate and is bent upward.
[0009] Moreover, the ends of the elastic sheet and the supporting sheet overlap each other.
[0010] Moreover, an upward arch is provided in the middle of the elastic piece.
[0011] The advantages and positive effects of the utility model are:
[0012] 1, The new structure terminal increases the auxiliary support sheet structure, so that the vibration resistance level is improved from V1 to V2 (the automobile vibration level is 4 levels, and V4 is the highest), and through repeated detection, the new structure terminal does not occur "flat PIN" problem caused by the inclined insertion of the public terminal in the actual application process.
[0013] 2, The internal structure of the female terminal is redesigned without changing the size of the female terminal, and the new female terminal is obtained, and the material cost of the new structure terminal is reduced by about 7%, and because the weight of the product is reduced, the transportation cost of the product is also reduced to a certain extent.

[0022] In order to make the structure and advantages of the utility model more clear, the structure of the utility model will be further described below in combination with the drawings.
[0023] The vertical direction, the horizontal direction, the front end, the rear end and the like in the embodiment are relative position descriptions, and the actual direction of the product is not limited.
[0024] The technical name used in the scheme is explained:
[0025] Terminal: The conductive part at one end of the wiring harness in the connector. The conduction between the wiring harnesses is connected through the terminal. In a pair of connected terminals, one end is a male terminal and the other end is a female terminal.
[0026] Spring clip: Generally, there is an elastic structure inside the female terminal, which is used to contact with the male terminal. The elastic structure can provide a certain pressure to ensure the reliability of the contact, and the contact will not be lost when subjected to a certain impact.
[0027] Yield: When a material is deformed by a load, it undergoes plastic deformation and cannot return to its original shape after the load is removed. Figure 1 A female terminal structure, wherein the female terminal 1 of the new structure is used for plugging and matching with the male terminal 2.
[0028] See attached Figures 2 to 4 The new structure female terminal 1 includes a plug-in channel, a spring piece 13, a protrusion, a support piece 12 and a tail wing. The plug-in channel and the tail wing are coaxially arranged and made into one piece. The plug-in channel is a square channel composed of a bottom plate, side plates on both sides and a top plate.
[0029] An integral spring piece 13 is provided on the bottom plate in the plug-in channel. The spring piece 13 is tilted upward from the direction of the tail wing of the socket. An upward arch is provided in the middle of the spring piece 13. The arch position can abut against the male terminal 2 to achieve effective connection between the male terminal 2 and the female terminal.
[0030] To prevent spring clip 13 from being squeezed and deformed, potentially causing contact failure, first protrusions 14 are symmetrically positioned in the middle of sidewall 11 on either side below spring clip 13. Second protrusions 15 are also located on sidewall 11 between first protrusion 14 and the inlet. When the male end is inserted at an angle, it pushes spring clip 13 downward. When spring clip 13 reaches the protrusions, it can no longer deform downward, thus protecting it from excessive deformation and yield failure.
[0031] To further prevent deformation of the spring clip 13, an upwardly tilted support piece 12 is provided on the base plate corresponding to the free end of the spring clip 13 within the insertion channel. The support piece 12 is integrally formed with the base plate and bent upward to provide elasticity, capable of limiting and supporting the end of the spring clip 13. A support piece 12 with a certain degree of elasticity is designed at the end of the spring clip 13. When the male terminal 2 is inserted, the spring clip 13 is pressed and deformed, and the support piece 12 generates a reverse elastic force on the spring clip 13. This elastic force also increases the pressure of the spring clip 13 on the male terminal 2, ensuring more reliable contact between the male and female terminals.
[0032] In this solution, due to the provision of the support sheet 12, the structural length of the spring sheet 13 needs to be shortened, and the sum of the length of the spring sheet 13 and the length of the support sheet 12 is close to the overall length of the insertion channel. Figure 6As shown, it can be seen that the shape of the new terminal structure after unfolding is shorter than that of the original structure after unfolding, so the new structure also reduces the amount of material used (about 7%), reduces the weight, and reduces the product cost.
[0033] The above merely describes the embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
