Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an integrated spring connector. Background Technology

[0002] In modern electrical and electronic equipment, connectors are key basic components for realizing the transmission and exchange of electrical signals or power. Their performance and reliability directly affect the stable operation of the entire system. Traditional wiring methods, such as screw terminals, although reliable, are cumbersome and inefficient. They require screwdrivers to tighten each screw individually, which not only consumes a lot of manpower and time, but also the operator's skill level and control of tightening torque directly affect the connection quality, easily leading to problems such as loose connections and loosening.

[0003] To improve wiring efficiency, various quick connectors, such as crimp or spring connectors, have emerged on the market. However, some spring connectors require operators to press the spring directly with their fingers when clamping the wires. For harder or thicker wires, this is very strenuous and can easily lead to finger fatigue or injury.

[0004] Meanwhile, many quick connectors require specific tools to pry open the spring clips during wiring operations, but these tools are often separate and easily lost during on-site construction, causing inconvenience for maintenance and operation. Utility Model Content

[0005] The purpose of this invention is to provide a connector that enables fast and reliable wire connection, ensures stable connection in harsh environments, and is easy to operate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an integrated spring connector, comprising a pin-type body and a hole-type body that engages with the pin-type body for insertion and removal; The needle-shaped body is provided with a first conductive component, which includes a first spring clip for pressing the wire and a first terminal. The first terminal is integrally formed with a first carrier body that cooperates with the first spring clip and a pin for electrical connection. The second conductive component is provided inside the hole-shaped body. The second conductive component includes a second spring clip for pressing the wire and a second terminal. The second terminal is integrally formed with a second carrier body that cooperates with the second spring clip and a clamping plate for holding the pin. Both the needle-shaped body and the hole-shaped body are provided with wiring holes for inserting wires and opening holes for inserting tools to pry open the spring clips.

[0007] As a further description of the above technical solution: a cover plate is snapped onto the opposite ends of the needle-shaped body and the hole-shaped body, the wiring hole is opened on the cover plate, and the opening hole is the first opening hole opened on the cover plate.

[0008] As a further description of the above technical solution: the sidewalls of the needle-shaped body and the hole-shaped body are also provided with a second opening hole as an opening hole, and the first opening hole and the second opening hole provide different entry channels for the operating tool.

[0009] As a further description of the above technical solution: the surface of the needle-shaped body is provided with a receiving groove, which is used to store a plug plate that can be used as a tool.

[0010] As a further description of the above technical solution: it also includes a locking assembly for locking the inserted pin-shaped body and hole-shaped body, wherein the outer side walls of the pin-shaped body and the hole-shaped body are provided with grooves; The locking assembly includes a rectangular plate with an integrally extended insert that can be inserted into the grooves of the pin-shaped body and the hole-shaped body.

[0011] As a further description of the above technical solution: both sides of the needle-shaped body and the hole-shaped body are provided with integrally formed locking blocks, and the rectangular plate is engaged with the holes of the locking blocks through the insertion post.

[0012] As a further description of the above technical solution: a reset spring and a slider are provided in the inner cavity of the insertion post. The slider can engage with the locking block under the push of the reset spring to lock the rectangular plate.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. The method of using spring clips to hold the wires in conjunction with the carrier body replaces the traditional screw fastening. This method is not only extremely fast, but the spring clips can also provide continuous and stable clamping force, effectively preventing the wires from loosening due to vibration and ensuring the long-term reliability of electrical connections. At the same time, it provides two tool access points on the front and side, which greatly enhances the product's installation adaptability in narrow or complex spaces.

[0014] 2. For applications with high vibration or extremely high reliability requirements, a locking assembly consisting of a rectangular plate, insert blocks, and insert posts with sliders is added to provide a second layer of physical locking for the docking of the pin-type body and the hole-type body. The locking assembly has a stable structure and can effectively resist strong vibration and impact, eliminating the risk of accidental separation of the connector and greatly improving the stability and safety of the connection.

[0015] 3. A slot for embedding magnetic material is designed on the connector body to store specially designed insertion tools. This solves the problem of special tools being easily lost during on-site construction, realizes the ability to retrieve tools as needed and manage them conveniently, and improves the user's ease of use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 Please see Figures 1-7 This utility model provides a technical solution: an integrated spring connector, including a pin-type body 10 and a hole-type body 11 that mates with it. The pin-type body 10 and the hole-type body 11 are preferably injection molded from engineering plastics (such as PBT, PA66, etc.) and have good mechanical strength and electrical insulation properties. At least two pairs of buckles are provided on the top of the pin-type body 10 and the hole-type body 11 for detachably locking the two together.

[0020] like Figure 1 and Figure 2 As shown, the needle-type body 10 and the hole-type body 11 are basically symmetrical in structure. Both are plastic frames used to accommodate internal conductive metal parts. At the ends of the needle-type body 10 and the hole-type body 11 that are far apart, a cover plate 12 is attached to them by several clips. The cover plate 12 serves to close the opening of the body, fix the internal components, and provide guidance for external wiring.

[0021] The cover plate 12 has multiple sets of parallel wiring holes 13 and first opening holes 14. The wiring holes 13 are circular and are used to guide the insertion of wires. The first opening holes 14 are square and serve as one of the operating entrances for the tool. Correspondingly, several second opening holes 15 are also provided on the side walls of the needle-type body 10 and the hole-type body 11, which are also used as insertion channels for operating tools, providing users with two operating methods, front or side, to adapt to different installation environments.

[0022] Inside the internal cavity of the needle-shaped body 10, there are several sets of first conductive components. Each set of first conductive components includes a spring clip 16 and a first terminal. The spring clip 16 is stamped from a highly elastic metal material (such as stainless steel or phosphor bronze). Its special geometry allows it to undergo elastic deformation when pried by a tool and quickly return to its original position after the external force is removed.

[0023] The first terminal is made of a metal with excellent conductivity (such as brass or phosphor bronze, and the surface is usually tin-plated or gold-plated to enhance conductivity and oxidation resistance). The first terminal is a rigid strip-shaped part formed in one piece.

[0024] One end of the first terminal is processed into a pin 18 for electrical connection with the second terminal inside the hole-shaped body 11; the other end forms a flat first carrier 19, which serves as a base for wire contact and fixation.

[0025] Similarly, several sets of second conductive components are also provided inside the hole-shaped body 11. Each set includes a spring clip 16 and a second terminal. The second terminal includes a second carrier 20 for carrying the wire and a clamp 21 that cooperates with the pin 18. When the pin 18 is inserted, the clamp 21 can clamp the pin 18 from two directions.

[0026] During assembly, the spring clips 16 are first pre-installed at designated positions on the first and second terminals to form a complete conductive terminal assembly. Then, these terminal assemblies are inserted one by one into the slots inside the pin-type body 10 and the hole-type body 11 from their open ends. After all the terminal assemblies are installed in place, the cover plate 12 is aligned and pressed so that its buckles engage with the corresponding structures on the main frame, thereby securely encapsulating all internal parts inside the main body.

[0027] The wiring operation steps are as follows: the operator selects a suitable tool, such as a flathead screwdriver or a special operating tool, and inserts the tip of the tool into the first opening hole 14 on the cover plate 12 or the second opening hole 15 on the main body.

[0028] refer to Figure 2 When inserted through the second opening hole 15, pressing the tool will cause the tool tip to press against a specific force point of the spring clip 16, causing it to deform. The end of the spring clip 16 used to hold the wire is pressed down, thereby opening the clamping space between the spring clip 16 and the first carrier 19 or the second carrier 20.

[0029] Insert the stripped wire into the circular connection hole 13 until the end of the wire touches the internal limiting structure. Remove the operating tool, and the spring clip 16 will instantly return to its original shape under its own elastic force. Its lower arm presses the wire tightly onto the first carrier 19 or the second carrier 20 with strong pressure, achieving a firm mechanical fixation and a reliable electrical connection. This process does not require the use of screws for tightening and is extremely quick and efficient.

[0030] When the needle-type body 10 and the hole-type body 11 need to be connected, the operator only needs to align the two and insert them. The buckles on both sides will automatically engage. At this time, the current path is established: external wire → spring clip 16 and first carrier 19 → pin 18 → clamp 21 → second carrier 20 and spring clip 16 → external wire on the other side, and finally the electrical signal or electrical energy is transmitted to the target device.

[0031] Example 2 As an improvement, this embodiment adds some convenient designs based on embodiment one. Specifically, refer to... Figure 5 A receiving groove 101 is provided on the surface of the needle-shaped body 10. Magnetic material can be embedded in the receiving groove 101. Its shape can match a specially made insert plate 22. The insert plate 22 can be used as a special tool to open the spring clip 16. When not in use, it can be stored in the receiving groove 101 by magnetic adsorption, which is convenient to carry and manage and prevents loss.

[0032] Example 3 To be applicable to applications with high vibration or extremely high requirements for connection reliability, this embodiment adds a locking component to the first embodiment.

[0033] Specifically, refer to Figure 2 , Figure 6 and Figure 7On the outer side wall of the needle-type body 10 and the hole-type body 11 after they are joined, there are grooves 23 for mating. The locking assembly includes a rectangular plate 24, on which an integrally extended insert 25 is provided. When the rectangular plate 24 is installed, the insert 25 will be inserted into the grooves 23 of the needle-type body 10 and the hole-type body 11.

[0034] In order to fix the rectangular plate 24 to the connector body, both sides of the pin-type body 10 and the hole-type body 11 are provided with integrally formed locking blocks 26, and the rectangular plate 24 is engaged with the holes of the locking blocks 26 through the insertion post 27.

[0035] To achieve the self-locking function of locking and unlocking, a return spring 28 and a slider 17 are provided in the inner cavity of the insert 27. Under the push of the return spring 28, the slider 17 always tends to extend outward. When the rectangular plate 24 is fully installed in place, the slider 17 will cross one edge of the locking block 26 and pop out, forming a locking engagement with the locking block 26, thereby preventing the rectangular plate 24 from accidentally disengaging.

[0036] When unlocking is required, simply press the slider 17 inward with your finger to disengage it from the latch 26, and the rectangular plate 24 can be easily removed. Then, the pin-type body 10 and the hole-type body 11 can be separated normally. This locking component provides a second layer of security for the connector, greatly enhancing the stability and reliability of the connection.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
