Description

Technical Field

[0001] The utility model relates to the field of electronic connectors, in particular to a terminal. Background Art

[0002] In electronic and communications equipment, flat cables and their terminals are crucial components for connecting electrical signals and are widely used in diverse scenarios. Terminals not only connect wires or conductors to other electrical components of the device, but also must ensure reliable and stable connections. Especially during production, terminal installation efficiency directly impacts the overall assembly line's output speed.

[0003] In the existing technology, the production process of electronic wiring harness terminals with pins is as follows: the terminals are crimped to the wires using a crimping machine, and then the crimped terminals are rotated 90 degrees and inserted into the plastic shell one by one. This traditional process has significant disadvantages and challenges:

[0004] 1. Terminal design issues: Conventional terminals have pins and the body of the terminal in the same plane. During the crimping process, the terminal must maintain a fixed orientation. However, because the pins are aligned with the body, the crimped terminal cannot be directly inserted into the housing. To accommodate the housing's installation requirements, the terminal must be rotated 90° to ensure smooth insertion. This rotation not only adds steps but also complicates the production process.

[0005] 2. Difficulties in Automated Assembly: In modern industrial production, the widespread use of automated equipment has become key to improving production efficiency. However, the design of existing terminals presents numerous obstacles to automated production. Because the terminal pins are aligned with the main body plane, automated equipment (such as automatic shell inserters) struggles to directly grasp and rotate the terminals. This prevents efficient terminal rotation during automated assembly, causing the automatic shell inserter to malfunction, significantly reducing assembly efficiency.

[0006] 3. Low operational efficiency: In the existing process, crimped terminals need to be rotated 90° before being inserted into the housing. This not only increases operational complexity but also significantly reduces production efficiency. Operation speed is limited, and problems such as angular deviation and improper insertion are prone to occur, resulting in unstable assembly quality.

[0007] Therefore, existing terminal designs require a 90° rotation after crimping, severely limiting the efficiency of automated production lines and increasing production costs and labor intensity. Furthermore, the resulting consistency issues and quality instability also increase product defect rates.

[0008] In view of this, the inventor specially designed a terminal, which resulted in the present invention. Utility Model Content

[0009] The purpose of this application is to provide a terminal, which mainly solves the problem that the existing terminal pin and the terminal body are located in the same plane, making it impossible to directly plug into the plastic shell, and need to be rotated 90° during the production process, resulting in low production efficiency, difficulty in automated assembly, poor plug-in operation reliability and unstable yield rate.

[0010] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0011] The present application provides a terminal, including a terminal body, which has a first end face and a second end face on the upper and lower sides, a clamping portion for fixing the wire is provided on one side of the first end face, and a conducting portion for plugging and conducting components is provided on the other side of the first end face, and a connecting portion for connecting the conductor in the wire is provided on the first end face and between the clamping portion and the conducting portion; a pin is fixedly provided between the connecting portion and the clamping portion, and the pin is vertically provided on the first end face.

[0012] In a further solution, the pin is fixedly arranged on the edge of the first end surface and close to the clamping portion.

[0013] In a further solution, a hook is further included for fixing the terminal body and the plastic shell.

[0014] In a further solution, the hook position is set on the second end surface of the terminal body.

[0015] In a further solution, two sides of the terminal body are bent perpendicularly to the plugging direction to form an arc shape.

[0016] In a further embodiment, the clamping portion includes two clamping pieces arranged opposite to each other for clamping the outer insulating layer of the wire.

[0017] In a further solution, a chamfer is provided above the guide portion.

[0018] In a further embodiment, the terminal body, the clamping portion, the conducting portion, the connecting portion, the hook and the pin are made of tinned copper. Beneficial effects

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] By positioning the pins vertically on the first end face of the terminal body, the traditional need for rotating pins is eliminated, simplifying the assembly process and significantly improving production efficiency, making it particularly suitable for automated production. Furthermore, the clearly defined separation between the clamping and conducting sections ensures reliable wire retention and electrical connection, enhancing product consistency and operational stability. Furthermore, the integrated structural design increases the strength and durability of the terminal, making it more robust during assembly, further reducing costs and improving product quality.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0029] This application provides a terminal with an improved structure, particularly suitable for connecting cables in electronic devices, enabling efficient automated assembly, improving production efficiency, and reducing costs. By optimizing the design and other structures of the terminal's pin 5, the present invention addresses the inefficiency of rotating the pin 5 in the prior art, ensuring reliability and stability during the terminal insertion process.

[0030] like Figure 1As shown, the terminal provided in this application includes a terminal body 1 having a first end face 11 and a second end face 12 on the upper and lower sides, respectively. The terminal body 1 is made of brass, phosphor bronze, or other materials, and may also be nickel-plated or tin-plated copper. These materials provide the entire terminal with excellent electrical conductivity, corrosion resistance, and durability, ensuring the terminal's electrical performance and mechanical strength over extended use.

[0031] like Figure 3 As shown, the clamping portion 2 is arranged on one side of the first end face 11 of the terminal body 1 and is used to fix the wire 7. The clamping portion 2 is composed of two clamping pieces arranged opposite to each other, which can clamp the outer insulation layer of the wire 7, thereby ensuring a firm connection between the wire 7 and the terminal. When the wire 7 is installed, the wire 7 can be fixed in the clamping portion 2 through a simple crimping operation, effectively preventing the wire 7 from loosening or falling off. At the same time, the inner surface of the clamping piece is designed with anti-slip grooves, which further enhances the fixing effect of the wire 7. This design not only improves the assembly efficiency, but also ensures the long-term and stable connection between the wire 7 and the terminal.

[0032] like Figure 2 As shown, the conductive portion 3 is arranged on the other side of the first end face 11 of the terminal body 1. The conductive portion 3 is used to connect with components in the electronic device and conduct electrical signals. The conductive portion 3 adopts a U-shaped opening structure. This design ensures stable physical contact with external components and guarantees the transmission of electrical signals or currents. At the same time, a chamfered structure is designed on the top of the conductive portion 3. This design helps guide the components to be inserted smoothly and prevents component jamming or errors during the insertion process. This not only reduces the risk of failure during the insertion process, but also reduces wear when plugging and unplugging components, thereby extending the service life of the terminal.

[0033] Connecting portion 4, located between clamping portion 2 and conducting portion 3, connects to the inner conductor of wire 7. The conductive metal portion of wire 7 is secured to connecting portion 4 by crimping or welding, ensuring smooth transmission of electrical signals from wire 7 to the terminal. To enhance the securement of wire 7, the inner surface of connecting portion 4 is provided with an indentation structure. This crimping operation securely secures the conductor in connecting portion 4, preventing loosening or poor contact.

[0034] like Figure 2As shown, the pin 5 is vertically fixed on the first end face 11, located between the clamping portion 2 and the connecting portion 4, and is arranged close to the clamping portion 2. This design helps when the terminal carrying the wire 7 is inserted into the plastic shell, the conductor in the wire 7 has a smaller leakage area, and the insulation effect is good, it is more dust-proof and reduces the chance of oxidation. The pin 5 is designed to be a vertical structure. Compared with the traditional design in which the pin 5 and the terminal body 1 are located in the same plane, the vertical pin 5 of this application does not need to be rotated during the plugging process, and multiple pins can be plugged in at the same time. Multiple terminals only need to be simply placed side by side to be inserted into the plastic shell at the same time. Unlike traditional terminals, which need to be rotated 90° each time before being inserted into the plastic shell, making it impossible to initially arrange them, thereby greatly improving the efficiency of production and assembly. In addition, the position and number of the pins 5 are set on a single side, the overall structure is simple, and the production cost is lower.

[0035] The advantage of this design is that it can be quickly plugged into the plastic shell, avoiding the problem of the existing technology that the pin 5 and the body need to be rotated 90 degrees because they are located in the same plane. It is suitable for automated production. The improved terminal structure not only improves production efficiency, but also significantly reduces production costs. It also improves the reliability and smoothness of the plug-in operation, thereby ensuring a high yield rate.

[0036] like Figure 2 As shown, the terminal of the present application also includes a hook 6 for securing the terminal body 1 in the plastic housing. The hook 6 is disposed on the second end face 12 of the terminal body 1 and has an elastic structure. When the terminal is inserted into the plastic housing, the hook 6 tightly engages with the internal slot of the plastic housing, forming a self-locking effect, thereby ensuring the tightness and stability of the terminal and the plastic housing. This design allows the terminal to remain fixed in the plastic housing after insertion, preventing the terminal from loosening or detaching from the plastic housing due to vibration or external forces during use.

[0037] The two sides of the terminal body 1 are bent inward perpendicular to the insertion direction to form an arc-shaped structure. This structural design not only enhances the mechanical strength of the terminal body 1, but also improves the flexibility of the terminal during the insertion process, making the terminal smoother when inserted and removed from the plastic shell, and reducing friction and wear during the insertion and removal process. The arc design also increases the terminal's resistance to bending in actual use, preventing the terminal from deforming or breaking when subjected to external forces. Another purpose of this design is that the arc structure can better and more stably wrap the wire 7, making the whole more stable.

[0038] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
