Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connector technology, and in particular to an electrical connector terminal structure with a self-locking spring. Background Technology
[0002] Electrical connector terminals are the core conductive components in electrical connectors, used to achieve reliable current conduction and signal transmission between two or more electrical devices, lines or modules. They are usually used in conjunction with pins and sockets and are key components to ensure stable circuit connections, low resistance, corrosion resistance and long life.
[0003] The existing announcement number is CN201430280Y, entitled "An Electrical Connector Terminal", which is used to electrically connect a chip module to a printed circuit board. It includes a first terminal, a second terminal, and an elastic member located between the first terminal and the second terminal. The first terminal has a base and a superimposed portion that bends and extends from the base. The end of the base has a first contact portion. The second terminal has a main body and a pair of arms that extend upward from the main body. The end of the main body has a second contact portion. The base and the superimposed portion respectively contact the arms, thereby increasing the distance between the arms, which is beneficial for the processing of the arms.
[0004] However, in use, the aforementioned electrical connector terminal structure lacks locking components when the pins and sockets are inserted, and the electrical connector terminals cannot be locked and fixed during insertion, resulting in poor stability when the electrical connector terminals are mated. Later mated electrical connector terminals become loose, leading to poor contact when the electrical connector terminals are mated. Utility Model Content
[0005] This invention solves the problems in related technologies and proposes an electrical connector terminal structure with a self-locking spring.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: an electrical connector terminal structure with a self-locking spring, including a mounting frame, a push-pull frame, and a pressing cone. The mounting frame has a U-shaped structure, and fixing holes are fixed to the bottom of the vertical end faces on both sides of the mounting frame. The fixing holes are used to fix the mounting frame. A terminal post is vertically connected and fixed on the bottom surface of the mounting frame, and a terminal plug is vertically fixed to the top of the terminal post. Anchor holes are horizontally opened on both sides of the mounting frame. The push-pull frame is vertically slidably inserted into the mounting frame. Inside, a wiring post is vertically connected and fixed on the bottom surface of the sliding frame. Anchor posts are horizontally slidably inserted on both vertical end faces of the sliding frame. An elastic frame is horizontally sleeved and fixed on the outside of the anchor posts. One end of the elastic frame is fixed to the vertical end face inside the sliding frame. The anchor posts are slidably inserted into the anchor holes. A screw hole is vertically opened through the top of the sliding frame. A pressing screw is vertically threaded through the screw hole of the sliding frame. A pressing cone is vertically set inside the sliding frame. The top of the pressing cone is rotatably connected to the bottom of the pressing screw.
[0007] As a preferred embodiment, the mounting frame has vertical grooves on both sides of its internal vertical end face, and anchor holes are horizontally drilled through both sides of the mounting frame.
[0008] As a preferred embodiment, slide bars are vertically fixed on both sides of the outer vertical end face of the push-pull frame, and the slide bars are slidably assembled with the slide grooves on the inner wall of the mounting frame.
[0009] As a preferred embodiment, the top two sides of the push-pull frame are vertically fixed with sliding rods, and springs are vertically sleeved on the outside of the sliding rods.
[0010] As a preferred embodiment, the top of the mounting frame is horizontally fixed with a hole block, and the hole block and the slide rod are vertically slidably inserted, with the two ends of the spring fixed to the top of the push-pull frame and the hole block, respectively.
[0011] As a preferred embodiment, the outer walls of the pressing cone are symmetrically provided with pressing slides on both sides, and the top of the pressing cone is vertically provided with a rotating groove, which is rotatably connected to the bottom end of the pressing screw.
[0012] As a preferred embodiment, a ball head is fixed at one end of the anchor post near the pressure cone block, and the ball head presses against the pressure slide.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the push-pull frame slides vertically down in the mounting frame, causing the wiring plug to press against and insert into the wiring plug cylinder of the wiring plug in the mounting frame. Then, the pressing screw on the top surface of the push-pull frame is rotated, pushing the pressing cone block to move vertically downward. The outside of the downward-moving pressing cone block presses against the anchor post in the push-pull frame and slides into the anchor hole of the mounting frame. Thus, the anchor post locks the position of the push-pull frame in the mounting frame, ensuring the stability of the wiring plug pressing against and inserting into the wiring plug cylinder of the wiring plug in the mounting frame, and ensuring the effectiveness of the contact.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0017] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0018] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0019] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0021] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
[0022] like Figures 1 to 5As shown, an electrical connector terminal structure with a self-locking spring includes a mounting frame 1, a push-pull frame 2, and a pressing cone block 3. The mounting frame 1 has a U-shaped structure, and fixing holes 13 are fixed to the bottom of the vertical end faces on both sides of the mounting frame 1. The fixing holes 13 are used to fix the mounting frame 1. A terminal post 11 is vertically connected and fixed on the bottom surface of the mounting frame 1, and a terminal plug 12 is vertically fixed to the top of the terminal post 11. Anchor holes 15 are horizontally opened through both sides of the mounting frame 1. The push-pull frame 2 is vertically slidably inserted into the mounting frame 1, and a terminal post 22 is vertically connected and fixed on the bottom surface of the push-pull frame 2. Anchor posts 26 are horizontally slidably inserted into the vertical end faces on both sides of the push-pull frame 2, and a spring frame 27 is horizontally sleeved and fixed to the outside of the anchor post 26. One end of the spring frame 27 is fixed to the vertical end face inside the push-pull frame 2. The anchor post 26 is slidably inserted into the anchor hole 15. The top of the push-pull frame 2 has a vertically penetrating screw hole 25, and a pressing screw 33 is vertically threaded through the screw hole 25 of the push-pull frame 2. The pressing cone 3 is vertically set inside the push-pull frame 2, and the top of the pressing cone 3 is rotatably connected to the bottom of the pressing screw 33. In use, the push-pull frame 2 is pressed down vertically in the mounting frame 1, which drives the wiring plug 22 to press against and insert into the wiring plug 12 of the wiring plug 11 in the mounting frame 1. Then, the pressing screw 33 on the top surface of the push-pull frame 2 is rotated, which pushes the pressing cone 3 to move vertically downward. The outside of the downward-moving pressing cone 3 presses against the anchor 26 in the push-pull frame 2 and slides into the anchor hole 15 of the mounting frame 1. Thus, the anchor 26 is used to lock the position of the push-pull frame 2 in the mounting frame 1, which ensures the stability of the wiring plug 22 pressing against and inserting into the wiring plug 12 of the wiring plug 11 in the mounting frame 1, and ensures the effectiveness of the contact.
[0023] In one embodiment, such as Figure 3 and 4 As shown, the mounting frame 1 has vertical grooves 14 on both sides of its internal vertical end face, and anchor holes 15 are horizontally through-holes on both sides of the mounting frame 1. The sliding frame 2 has vertically fixed sliders 21 on both sides of its external vertical end face, and the sliders 21 are slidably assembled with the grooves 14 on the inner wall of the mounting frame 1. The top two sides of the sliding frame 2 have vertically fixed sliders 23, and springs 24 are vertically sleeved on the outside of the sliders 23. The top of the mounting frame 1 has horizontally fixed holes 16, and the holes 16 are vertically slidably inserted with the sliders 23. The two ends of the springs 24 are respectively fixed to the top of the sliding frame 2 and the holes 16. In use, pressing the sliding frame 2 makes it slide vertically down in the mounting frame 1, pushing the sliders 23 to slide vertically on the holes 16, compressing the springs 24 to deform, and vertically guiding the wiring plugs 22 to press against and insert into the wiring plugs 12 of the wiring plugs 11 of the mounting frame 1.
[0024] In one embodiment, such as Figure 4 and 5As shown, the outer walls of the pressure cone 3 are symmetrically provided with pressure slides 31 on both sides, and the top of the pressure cone 3 is vertically provided with a rotating groove 32, which is rotatably connected to the bottom end of the pressure screw 33. The end of the anchor 26 near the pressure cone 3 is fixed with a ball head 28, which presses against the pressure slide 31. During use, the pressure screw 33 on the top surface of the push-pull frame 2 is rotated to push the pressure cone 3 to move vertically downward. The ball head 28 at the end of the anchor 26 in the push-pull frame 2, which moves downward, presses against the outside of the pressure cone 3 and slides in the pressure slide 31 of the pressure cone 3, pushing the anchor 26 to insert into the anchor hole 15 of the mounting frame 1. Thus, the anchor 26 is used to lock the position of the push-pull frame 2 in the mounting frame 1, ensuring the stability of the wiring plug 22 pressing against the wiring plug 11 in the wiring plug 12 of the mounting frame 1, and ensuring the effectiveness of the contact.
[0025] In this embodiment, during use, the push-pull frame 2 slides vertically down in the mounting frame 1, causing the wiring plug 22 to press against and insert into the wiring plug 12 of the wiring plug 11 in the mounting frame 1. Then, the pressing screw 33 on the top surface of the push-pull frame 2 is rotated, pushing the pressing cone 3 to move vertically downward. The moving pressing cone 3 presses against the anchor 26 in the push-pull frame 2 and slides into the anchor hole 15 in the mounting frame 1. Thus, the anchor 26 is used to lock the position of the push-pull frame 2 in the mounting frame 1, ensuring the stability of the wiring plug 22 pressing against and inserting into the wiring plug 12 of the wiring plug 11 in the mounting frame 1.
[0026] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
