[0050] The detailed description and technical content of this application will be described below in conjunction with the accompanying drawings. However, the accompanying drawings are only for illustrative purposes and are not intended to limit this application.
[0051] Please refer to Figures 1 to 8 As shown, this application provides a female terminal module and its leaf spring type terminal structure for a terminal block 100 and a male terminal 200. This female terminal module 10 mainly includes a conductive sheet 1 and two leaf spring type terminal structures 2. The leaf spring type terminal structure 2 mainly includes a movable frame 21, a plurality of terminals 22 and / or a plurality of elastic arms 23.
[0052] As Figures 1 to 8 shown, the conductive sheet 1 is installed inside the terminal block 100. The shape of the conductive sheet 1 is U-shaped, but not limited thereto. The conductive sheet 1 has two support arms 11, and the inner sides of the two support arms 11 have two opposite inner side walls 12.
[0053] As Figures 1 to 8As shown, each leaf spring type terminal structure 2 is respectively installed on each support arm 11. When the male terminal 200 is inserted into the terminal block 100, the male terminal 200 is inserted between two leaf spring type terminal structures 2 and electrically connected to the conductive sheet 1 through the two leaf spring type terminal structures 2. Each leaf spring type terminal structure 2 includes a movable frame 21, a plurality of terminals 22, and one or more elastic arms 23.
[0054] Specifically described as follows, one of each support arm 11 and each movable frame 21 is provided with one or more grooves 3, and the other of each support arm 11 and each movable frame 21 extends one or more sliders 4 that can be slidably engaged with the one or more grooves 3, so that each movable frame 21 is movably connected to each support arm 11 and can approach or move away from the inner wall 12, that is, each movable frame 21 can approach or move away from each inner wall 12 relatively.
[0055] Among them, the number of grooves 3 and sliders 4 in this embodiment are eight respectively, but it is not limited thereto. Four sliders 4 protrude from the top and bottom of each support arm 11 respectively. Each movable frame 21 has two U-shaped frames 211 arranged corresponding to each inner wall 12. Two grooves 3 are opened from both ends of each U-shaped frame 211, so that the U-shaped frame 211 can be sleeved outside the slider 4 of the support arm 11 through the groove 3 and can slide relative to the slider 4, so as to achieve that the movable frame 21 can approach or move away from each inner wall 12 relatively.
[0056] Moreover, the inner side surface of each slider 4 has an inclined surface 41 with a gradually increasing thickness in the direction approaching the support arm 11. The inclined surface 41 is used to guide the U-shaped frame 211 to be installed from the inner side surface of the slider 4, so that both ends of the U-shaped frame 211 can abut and slide along the inclined surface 41 until the slider 4 penetrates through the groove 3.
[0057] In addition, a plurality of terminals 22 extend from each movable frame 21 in a direction away from the inner wall 12. Each terminal 22 in this embodiment is an arc-shaped convex strip 221 that integrally extends at both ends and straddles between two U-shaped frames 211 and is used to abut against the male terminal 200, but it is not limited thereto. Each terminal 22 can also be a convex strip with any geometric shape such as a V-shaped or W-shaped strip that integrally extends at both ends and straddles between two U-shaped frames 211 and is used to abut against the male terminal 200.
[0058] Furthermore, the elastic arms 23 extend from each movable frame 21 in a direction approaching the inner wall 12 and abut against the inner wall 12. The number of elastic arms 23 in this embodiment is multiple. Each elastic arm 23 is a V-shaped convex strip 231 with one end extending from one U-shaped frame 211 and a distance S formed between the other end and the other U-shaped frame 211, but it is not limited thereto. Each elastic arm 23 can also be a convex strip with any geometric shape such as a U-shaped or W-shaped strip with one end extending from one U-shaped frame 211 and a distance S formed between the other end and the other U-shaped frame 211.
[0059] Furthermore, the multiple arc-shaped ridges 221 and the multiple V-shaped ridges 231 of each leaf spring type terminal structure 2 in this embodiment are arranged alternately with each other, that is, the multiple terminals 22 and the multiple elastic arms 23 are arranged alternately with each other. Since the leaf spring type terminal structure 2 is made by first stamping and cutting a conductive metal sheet and then bending it, the multiple terminals 22 and the multiple elastic arms 23 are arranged alternately with each other, which can avoid stamping unnecessary cutting grooves on the conductive metal sheet and save a lot of waste such as copper plate waste generated during the manufacturing process.
[0060] As Figures 4 to 6 shown, the usage state of the relatively thin male terminal 200 of this application inserted into the female terminal module 10 of this application. Since each movable frame 21 can approach or move away from each inner side wall 12, when the male terminal 200 is inserted between the two leaf spring type terminal structures 2, it will compress each elastic arm 23, so that the leaf spring type terminal structure 2 can adjust the distance between the movable frame 21 and the inner side wall 12 through the compressed elastic arms 23; As Figures 7 to 8 shown, the usage state of the relatively thick male terminal 200 of this application inserted into the female terminal module 10 of this application. Since the thickness of the male terminal 200 is relatively thick, when the male terminal 200 is inserted between the two leaf spring type terminal structures 2, it will compress each elastic arm 23 more, causing the movable frame 21 to move closer to the inner side wall 12.
[0061] Thereby, the leaf spring type terminal structure 2 can adjust the distance between the movable frame 21 and the inner side wall 12 through the compressed elastic arms 23, and further enable the elastic arms 23 and the movable frame 21 to share the pressure borne by the terminals 22. When the female terminal module 10 of this application is paired with male terminals 200 of different thicknesses, it can avoid the situations of excessive compression deformation of the terminals 22 and excessive tight clamping of the male terminals 200, so as to achieve the advantages that the female terminal module 10 and the leaf spring type terminal structure 2 of this application are widely applicable to male terminals 200 of different brands or models.
