Abstract
Description
Technical Field
[0001] This utility model relates to a connector terminal, specifically a centipede-leg short clamp connector terminal. Background Technology
[0002] Connector terminals are a key component of a connector, primarily used for securing wires and transmitting signals in electrical connections. Connectors are a broad category, comprising a housing and terminals. The housing provides insulation, while the terminals handle the conductive metal parts, ensuring reliable transmission of current or signals. Specifically, a terminal is typically a metal strip encased in insulating plastic, with clips at both ends for easy insertion of wires.
[0003] Existing connector terminals have a complex and poorly designed structure. The metal contacts used for inserting wires lack elasticity, resulting in poor wire gripping. The pre-defined gap width on the metal contacts for wire insertion is fixed, leading to a high probability of wire detachment and poor stability. Furthermore, the metal contacts on the connector terminals lack a structure to guide the wire insertion position, potentially causing incorrect insertion and subsequent wear. Therefore, the inventors have improved the structure of the connector terminals. Utility Model Content
[0004] The purpose of this utility model is to provide a centipede-leg short clamp connector terminal. This connector terminal has a simple structure and reasonable design. The whole structure formed by the inner end and the outer end is in the shape of a centipede leg, which has a certain elasticity and can deform within a certain range and return to its original position. Therefore, it can clamp the wire that crosses the outer end, preventing the wire from falling off the metal contacts during use, ensuring the stability of the wire after long-term use. During the insertion process, the wire is guided by the guide protrusion to more accurately enter the area between the two outer ends, without the phenomenon of incorrect insertion or wear due to incorrect insertion. It solves the problems mentioned in the above technical background.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a centipede-leg short clamp connector terminal, the connector terminal including a terminal plate, on which a plurality of plate body protrusions are fixed at intervals, and at the end of each of the plurality of plate body protrusions away from the terminal plate, a metal antenna and a pin located on one side of the metal antenna are provided, the metal antenna including an inward end and a fixing head and an outward expansion end respectively fixed to both ends of the inward end, the whole formed by the inward end and the outward expansion end is in the shape of a centipede leg, the pin including an inner connecting pin and a positioning head, the two ends of the inner connecting pin being fixed to the plate body protrusion and the positioning head respectively.
[0006] Preferably, it also includes an L-shaped terminal unit, which includes a back end and a horizontal end fixed to the back end. A reinforcing piece is fixed on the horizontal end and attached to its surface. The reinforcing piece reinforces the horizontal end, making the structure of the back end and the horizontal end more stable.
[0007] Preferably, the horizontal end away from the back end is fixed to the inner connecting foot, and the back end away from the inner connecting foot extends toward the side of the plate protrusion away from the metal antenna.
[0008] Preferably, a curved foot is formed between the inward end and the outward end, and an included angle is formed between the inward end and the outward end, the value of which is between 70° and 110°.
[0009] Preferably, there are two sets of metal tentacles, and the two sets of metal tentacles are symmetrically arranged at both ends of the pin.
[0010] Preferably, there are two fixing heads, which are arranged in parallel and both are fixed to the end of the plate extension that is away from the terminal plate.
[0011] Preferably, a guide boss is fixed at one end of the positioning head near the inward end, and the thickness of the guide boss is between 0.18 mm and 0.2 mm.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a centipede-leg short clamp connector terminal. The centipede-leg short clamp connector terminal includes a terminal plate, on which multiple spaced plate extensions are fixed. At the end of each plate extension away from the terminal plate, a metal antenna and a pin located on one side of the metal antenna are provided. The overall structure is simple and reasonably designed. Two sets of metal antennas are provided, and the two sets of metal antennas are symmetrically arranged at both ends of the pin. The metal antenna includes an inner retracted end and a fixing head and an outer expansion end respectively fixed to both ends of the inner retracted end. A curved leg is formed between the inner retracted end and the outer expansion end. The whole formed by the inner retracted end and the outer expansion end is centipede-leg shaped, with a certain elasticity and extensibility. It can deform within a certain range and return to its original position. Therefore, it can clamp the wire that crosses the outer expansion end, apply pressure to the wire, and prevent the wire from falling off the metal antenna during use, ensuring the stability of the wire after long-term use. It is suitable for widespread use.
[0013] 2. The plug in this utility model includes an inner connecting pin and a positioning head. The two ends of the inner connecting pin are fixed to the protruding part of the plate and the positioning head, respectively. A guide boss is fixed at the end of the positioning head near the inward end. Through the guide boss, the wire will be guided by the guide boss during the insertion process, so as to enter the area between the two outward expansion ends more accurately, and avoid the phenomenon of incorrect insertion. After the wire passes through the two outward expansion ends, it can smoothly connect with the metal contact, accurately complete the wire insertion work, make the wire installation smoother, and prevent wear due to incorrect insertion. It is highly practical. Attached Figure Description

Multiple plate extensions 2 are fixed on the terminal plate 1 at intervals. Each of the multiple plate extensions 2 is fixed with an L-shaped terminal unit 3. Each of the multiple plate extensions 2 is provided with a metal antenna 4 and a pin 5 located on one side of the metal antenna 4. Two sets of metal antennas 4 are provided, and the two sets of metal antennas 4 are symmetrically arranged at both ends of the pin 5.
[0020] Please see Figure 2Terminal unit 3 includes a back end 31 and a horizontal end 32 fixed to the back end 31. A reinforcing piece 33 is fixed on the horizontal end 32 and adheres to its surface. The reinforcing piece 33 reinforces the horizontal end 32, making the structure of the back end 31 and the horizontal end 32 more stable. Metal antenna 4 includes an inward end 42 and a fixing head 41 and an outward end 43 fixed to both ends of the inward end 42. Pin 5 includes an inner connecting pin 51 and a positioning head 52. The two ends of the inner connecting pin 51 are fixed to the plate extension 2 and the positioning head 52, respectively. The end of the horizontal end 32 away from the back end 31 is fixed to the inner connecting pin 51, and the end of the back end 31 away from the inner connecting pin 51 extends toward the plate extension 2 on the side away from the metal antenna 4.
