Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of connectors, in particular to a stable wiring harness terminal structure. Background Art
[0002] Various electronic products, including devices containing electronic equipment and vehicles, require wiring harness terminal structures when connecting lines, such as Figure 4 As shown, the existing wiring harness terminal structure mainly realizes the plug-in function through the contact spring structure, and the existing contact spring structure is prone to deformation during the process of pressing the wiring harness, and it is difficult to control the distance and space formed between the contact springs. When the distance and space formed between the contact springs are too large, the terminal is easy to loosen during plugging. When the distance and space formed between the contact springs are too small, the terminal is too tight and difficult to plug. Even after plugging, when the contact spring is stretched to exceed its restorable deformation space, it is easy to deform abnormally after multiple plugging, resulting in poor terminal stability. Summary of the invention
[0003] The utility model is to overcome the shortcomings of the prior art and provide a stable wiring harness terminal structure. By adding a limit strip and a limit opening structure, the contact springs are kept stably formed with a fixed size opening during the process of pressing the terminal to bind the wiring harness, so as to avoid the contact springs of the terminal from being too small or too large, and to prevent the terminal from being loose or difficult to plug in during the plugging process. The utility model is applicable to the field of connector technology.
[0004] The technical solution adopted by the utility model is: a stable wiring harness terminal structure, including a trunk, a first holding ring is provided at the front of the trunk, and a second holding ring and a third holding ring are further provided at the rear of the trunk to wrap the rear of the binding wiring harness, thereby improving the stability of the connection between the wiring harness and the terminal, a fixing plate is provided at the rear end of the trunk to facilitate the terminal to be fixed on the component, a pair of contact springs extending forward are provided on the side of the first holding ring, and the contact springs are recessed towards each other to form a gourd-shaped mouth that is convenient for plugging, and during the process of terminal plugging, the other end is inserted into the gourd-shaped mouth to form a connection, the front end of the trunk slightly exceeds the front end position of the contact spring, and an annular limiting opening is extended from the front end of the trunk to the side where the contact spring is located, and the limiting opening can limit the activity space of the male terminal when the male terminal is inserted into the contact spring, thereby improving the stability of the terminal connection; The two ends of the opening of the first holding ring each extend forward to form a limit strip that fits each other, and the front end of the limit strip is connected to the annular opening of the limit opening. When the wiring harness is fixed on the terminal, the terminal needs to be pressed so that the wiring harness is wrapped and fixed by the holding ring. Most terminals are made of conductive metal materials such as copper and phosphor bronze. It is not easy to ensure the position of the two contact springs during the pressing process. The limit opening and the limit strip combination surround the contact spring to limit the contact spring from being subjected to external force and to limit the contact spring so that it will not be deformed due to excessive squeezing of the first holding ring, so as to ensure that a fixed-size opening is stably formed between the contact springs; a chamfer for limiting is also provided at the interface of the first holding ring. When the terminal is installed in the connector, the chamfer can be against the hanging platform inside the connector terminal installation port to prevent the terminal from detaching from the connector and improve the stability of the terminal.
[0005] A more optimal and stable wiring harness terminal structure is characterized in that the limiting opening is a square ring structure, which has better pressure resistance and further ensures the stability of the position of the contact spring.
[0006] The beneficial effect of this solution is that in the process of pressing the terminals to bind the wiring harness, the opening of a fixed size can be kept stably between the contact springs, avoiding the contact springs of the terminals from being too small or too large, and preventing the terminals from becoming loose or difficult to plug in during the connection process.

[0014] The utility model provides a stable wiring harness terminal structure, which is applicable to the technical field of connectors.
[0015] The utility model can be implemented in the following ways:
[0016] like Figure 1-3 As shown: a stable wiring harness terminal structure, including a trunk 6, a first holding ring 2 is provided at the front of the trunk 6, and a second holding ring 3 and a third holding ring 4 are further provided at the rear of the trunk 6 to wrap the rear of the binding wiring harness to improve the stability of the connection between the wiring harness and the terminal. The third holding ring 4 is also called a rubber-covered wire foot, which is mainly used to wrap and fix the wire part with rubber. The second holding ring 3 is also called a core-covered foot, which is mainly used to wrap and fix the inner core copper wire part of the wire. A fixing plate 5 is provided at the rear end of the trunk 6 to facilitate the terminal to be fixed on the component. A pair of contact springs 1 extending forward are provided on the side of the first holding ring 2. The contact springs 1 are recessed in opposite directions to form a gourd-shaped shape for convenient plugging. During the process of terminal plugging, the other end is inserted into the gourd-shaped shape to form a connection. The front end of the trunk 6 slightly exceeds the front end position of the contact spring 1, and a ring-shaped limit opening 22 is extended from the front end of the trunk 6 to the side where the contact spring 1 is located. The limit opening 22 is inserted into the contact When the spring piece 1 is in contact with the male terminal, it can limit the activity space of the male terminal and improve the stability of the terminal connection; the two ends of the opening of the first holding ring 2 extend forward to form a limit strip 21 that fits each other, and the front end of the limit strip 21 is connected to the annular opening of the limit opening 22. When the wiring harness is fixed on the terminal, the terminal needs to be pressed so that the wiring harness is wrapped and fixed by the holding ring. Most terminals are made of conductive metal materials such as copper and iron. It is not easy to ensure the position of the two contact springs 1 during the pressing process. The limit opening 22 and the limit strip 21 combine to surround the contact spring piece 1 to limit the contact spring piece 1 from being subjected to external force and to limit the contact spring piece 1 so that it will not be deformed due to excessive squeezing of the first holding ring 2, so as to ensure that a fixed-size opening is stably formed between the contact spring pieces 1; the interface of the first holding ring is also provided with a chamfer for limiting. When the terminal is installed in the connector, the chamfer can be against the hanging table inside the terminal installation port of the connector to prevent the terminal from detaching from the connector.
[0017] More preferably, a stable wiring harness terminal structure is characterized in that the limiting opening 22 is a square ring structure, which has better pressure resistance and further ensures the stability of the position of the contact spring 1.
[0018] The beneficial effect of this solution is that during the process of pressing the terminals to bind the wiring harness, the opening of a fixed size between the contact springs 1 can be kept stable, avoiding the contact springs 1 of the terminals from being too small or too large, and preventing the terminals from becoming loose or difficult to plug in during the connection process.
