Description

Technical Field

[0001] This utility model relates to the field of connectors, specifically to a split-type anti-finger-splitting socket structure. Background Technology

[0002] With the rapid development of electric vehicles and new energy storage devices, the requirements for electrical connectors are constantly increasing. Electrical connectors not only need to meet basic connection functions, but also need to have good finger-proof performance to ensure operational safety.

[0003] Currently, the anti-touch finger design in punched slotted sockets mainly falls into two categories: the first type of anti-touch finger usually uses a combination of a metal post and an insulating cap, which is installed and fixed by means of threads or riveting; the second type is to encapsulate metal parts with rubber injection molding and then assemble them.

[0004] The first approach is costly, complex, and non-removable, and is often used for deep rooting of machined terminals. In the punching of slotted terminals, due to process issues, it is difficult to guarantee the consistency of the machining clearance and roundness of the slotted socket cantilever. Direct deep rooting will cause wear and compression on the slotted cantilever, thus affecting the ease of assembly and electrical performance. The second approach is to use injection molding separately, which adds an assembly step, making it impossible to achieve simple and fast mass production of terminals. Utility Model Content

[0005] The purpose of this invention is to solve the problem of existing finger styluses not being able to deeply penetrate the punched grooves through structural and process improvements, and to avoid interference issues with the mold for integrally injection-molded anti-finger rods in the punched groove insertion holes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A split-type anti-touch finger split groove socket structure includes a socket body and an insulating base. The socket body and the insulating base are integrally injection molded. The insulating base is provided with a mounting hole for connecting an insulating touch finger that is coaxially arranged with the socket body. The wall surface of the socket body is provided with a split groove along the axial direction.

[0008] In the above technical solution, the wall surface of the socket body is provided with a number of slots along the axial direction, and the slots punch the wall surface of the socket body into a number of cantilevered sections.

[0009] In the above technical solution, the surface of the insertion hole body is fitted with a hoop, the outer surface of the cantilever is provided with a limiting groove, and the hoop is disposed in the limiting groove.

[0010] In the above technical solution, a limiting protrusion is provided on the cantilever next to the limiting groove.

[0011] In the above technical solution, the insertion hole is located inside the sleeve.

[0012] In the above technical solution, the insulating contact finger and the mounting hole are interference-fitted.

[0013] In the above technical solution, the end of the insulating contact finger is provided with an outwardly protruding spline, and the mounting hole is provided with an inwardly recessed step, and the spline and the step are engaged.

[0014] In the above technical solution, the assembly of the structure includes the following processes:

[0015] The metal sheet is integrally stamped into the socket body using a stamping process;

[0016] The insulating material is used to form an insulating base through an overmolding process, which is then integrally formed with the socket body.

[0017] Injection molding insulating material into insulating contact fingers;

[0018] The insulating contact finger is inserted into the insulating base from the opening of the socket body and connected to the insulating base as a whole using an interference fit method;

[0019] Assemble the clamp and sleeve on the socket body.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] This solution utilizes a stamped insertion hole structure and process to achieve integral molding with the base. By using a post-installation contact finger process, it effectively solves the problem that existing contact fingers cannot be deeply embedded in the stamped slot; it reduces the process of first injection molding and then assembling existing injection molded contact fingers; and it solves the problem of interference between the integral injection molded contact finger rod mold in the stamped slotted insertion hole.

[0022] The sleeve used for the socket body in this solution is made of stainless steel, which meets the strength requirements without requiring additional processing; the clamp is made of stainless steel wire, which ensures strength while reducing cost requirements. Attached Figure Description

[0023] This utility model will be described by way of example and with reference to the accompanying drawings, wherein:

[0024] Figure 1 This is a structural cross-sectional view of this embodiment;

[0025] Figure 2 This is a schematic diagram of the connection of the insulated contact fingers;

[0026] Figure 3 This is a schematic diagram of the socket body;

[0027] Figure 4 This is a schematic diagram of the socket body and the sleeve.

[0028] Wherein: 1 is the base, 2 is the contact finger, 3 is the cantilever, 4 is the sleeve, 5 is the hoop, 6 is the limiting groove, 7 is the limiting protrusion, 8 is the guide protrusion, 9 is the spring buckle, and 10 is the locking groove. Detailed Implementation

[0029] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0030] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0031] like Figure 3 As shown, in this embodiment, the socket body is integrally formed by stamping a single piece of metal. The contact section of the socket body is stamped with several slots along its axial direction, and several independent cantilever arms 3 are formed between the slots, so that the cantilever arms 3 have a certain elasticity under stress.

[0032] A limiting groove 6 is provided at a corresponding position on the outer surface of each cantilever 3. The limiting groove 6 is used to install the hoop 5. Under the action of all the limiting grooves 6, the hoop 5 can be wrapped around the entire insertion body. The hoop 5 plays a role in closing the cantilever 3, preventing the pin and the insertion hole from springing back and failing during the insertion process, and ensuring the reliability of the contact.

[0033] To ensure the stability of the hoop 5 installation and prevent displacement, a limiting protrusion 7 is provided on the cantilever 3. The limiting protrusion 7 is located next to the limiting groove 6. When the hoop 5 is about to leave the limiting groove 6, the limiting protrusion 7 will block the hoop and ensure that the hoop 5 cannot leave the limiting groove 6.

[0034] like Figure 4 As shown, the entire socket body needs to be set inside the sleeve 4. The sleeve 4 is provided with a guide protrusion 8 and a spring buckle 9, and the socket body is provided with a locking groove 10, so that the socket body and the sleeve 4 can be installed and disassembled independently.

[0035] In this embodiment, the cantilever 3 of the slotted structure needs to be fitted with a finger 2, such as... Figure 2 As shown. Both the contact finger 2 and the base 1 are made of insulating material. In this embodiment, they are manufactured into different components using independent processes, and then assembled using different processes, such as... Figure 1 As shown, specifically:

[0036] First, using an overmolded injection molding process, the insulating material is integrally injection molded with the socket body at the bottom, so that the socket body and the base 1 form a complete whole; a connecting hole is provided on the base 1, and an inner step is provided in the connecting hole for connecting the contact finger 2.

[0037] The insulating contact finger 2 is integrally molded using injection molding. The connecting end of contact finger 2 has a spline structure to prevent rotation after connection with the base 1. The connecting end of contact finger 2 employs an interference fit design, allowing contact finger 2 to interlock with the connecting hole of the base 1. To increase the strength of contact finger 2, reinforcing ribs can be added to the contact finger 2 rod.

[0038] In this embodiment, the end face of the finger 2 can be designed as a petal-shaped structure, with each petal having a corresponding outwardly protruding spline. The finger passes through the connecting hole on the base 1 using the elastic contraction of the petal-shaped structure, and the connection between the finger and the connecting hole is achieved by the spline engaging with the inner step on the connecting hole. After connection is complete, the finger 2 can rotate axially within the socket.

[0039] In this embodiment, the stamped insertion body has a semi-circular slot on its rear end. The slotted structure facilitates the insertion of the mold and the installation and positioning of the touch finger during injection molding, as the slotted structure can reserve a gap.

[0040] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
