Description

Technical Field

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

[0002] A connector, a device that connects two active components, is an electronic component used to transmit and exchange current or optical signals between electronic system devices. The connector has internal terminals, which are the primary means of achieving electrical connectivity.

[0003] As the connection terminals are used for a longer period of time, they will become worn out or become inoperable for other reasons, requiring replacement. Taking existing trams as an example, after a tram has traveled a certain distance, it will run out of power, requiring an external power source to recharge the battery inside the tram. A common charging structure involves plugs extending from a charging pile, with the socket located inside the tram. Charging is achieved by inserting the plugs into the socket and conducting current. Each plugging and unplugging of the plugs causes a certain amount of wear and tear on the socket, and after prolonged use, the socket inside the tram will become damaged. Repairing or replacing the socket requires disassembling the corresponding structure of the tram, a relatively complex process that results in high costs and poor convenience. Utility Model Content

[0037] Example 1

[0038] like Figure 1 and Figure 2 As shown, Figure 1 This is one of the three-dimensional structural diagrams of the connection terminal; Figure 2 This is a cross-sectional schematic diagram of a connection terminal. The connection terminal comprises a connector 1, a conductor 2, a first spring 3, a second spring 4, and a locking member 5. The conductor 2 and the connector 1 are detachably connected via the locking member 5. The first spring 3 is positioned at the junction of the connector 1 and the conductor 2, and between the connector 1 and the conductor 2. The second spring 4 is positioned at the end of the conductor 2 away from the connector 1. During use, an external pin is inserted into the conductor 2. When powered on, current flows between the external pin, the conductor 2, the first spring 3, and the connector 1.

[0039] Refer to it again Figure 3 As shown, Figure 3The figure is a schematic diagram of the three-dimensional structure of the connector 1. The connector 1 has a first receiving groove 11 and a second receiving groove 12. The first receiving groove 11 is connected to the second receiving groove 12. One end of the conductor 2 is located in the first receiving groove 11. The first spring 3 is also located in the first receiving groove 11. One side of the first spring 3 abuts against the conductor 2, and the other side of the first spring 3 abuts against the inner wall of the second receiving groove 12. The locking member 5 is inserted through the conductor 2 and the second receiving groove 12. In other words, a portion of the locking member 5 is located in the conductor 2, and the other portion of the locking member 5 is located in the second receiving groove 12. The conductor 2 and the connector 1 are connected as a whole by the locking member 5. Specifically, the locking member 5 is threadedly connected to the inner wall of the second receiving groove 12. That is, the locking member 5 is a bolt, and the inner wall of the second receiving groove 12 is provided with a corresponding thread. By rotating the locking member 5, it can be moved in the second receiving groove 12, thereby achieving the purpose of connecting the conductor 2 and the connector 1 as a whole. In this embodiment, the first and second accommodating grooves 11, 12 are formed along the length of the connector 1. The first and second accommodating grooves 11, 12 have different inner diameters, with the first accommodating groove 11 having a larger inner diameter than the second accommodating groove 12. In other words, the first and second accommodating grooves 11, 12 are arranged in the form of stepped holes. In practical applications, the end of the connector 1 away from the first accommodating groove 11 is flat, and the cable is connected to this flat structure to conduct current.

[0040] Refer to it again Figure 4-Figure 6 , Figure 4 is a side view of conductor 2; Figure 5 is a schematic diagram of the three-dimensional structure of the conductor 2; Figure 6 It is another schematic diagram of the three-dimensional structure of the conductor 2. The conductor 2 has a receiving chamber 21, which is connected to the first receiving groove 11. The locking piece 5 is located in the receiving chamber 21; when in use, the external pin is inserted into the receiving chamber 21. Furthermore, one end of the conductor 2 also has a mounting post 22, which is located in the first receiving groove 11. The first spring 3 is located between the mounting post 22 and the inner wall surface of the first receiving groove 11, and the first spring 3 abuts against the mounting post 22 and the inner wall surface of the first receiving groove 11. The conductor 2 also has a plurality of elastic sheets 23, which are arranged around the edge of one end of the mounting post 22, and the plurality of elastic sheets 23 are distributed at intervals. The plurality of elastic sheets 23 and the mounting post 22 together constitute the receiving chamber 21. It is further explained that the receiving chamber 21 can be understood as a through hole opened along the length direction of the conductor 2. When in use, the mounting post 22 contains a portion of the accommodating chamber 21, and the locking member 5 is located in the accommodating chamber 21 of this portion, and passes through the accommodating chamber 21 of this portion to connect with the second accommodating groove 12; in this embodiment, one end of the locking member 5 is located at the end of the mounting post 22 away from the connecting seat 1, and the other end of the locking member 5 is located in the second accommodating groove 12.

[0041] Please review Figure 4The elastic sheet 23 extends from one end of the connector 1 toward a position near the middle. When multiple elastic sheets 23 are extended in the same manner, a constriction will be formed. When in use, when an external pin is inserted into the partial accommodation chamber 21 surrounded by multiple elastic sheets 23, the constriction will abut against the external pin, so that multiple elastic sheets 23 abut against the external pin. Furthermore, in order to facilitate the insertion of the external pin, the end of the elastic sheet 23 away from the connector 1 is turned outward. It should be noted that the portion near the middle is considered inside, and the portion away from the middle is considered outside. Preferably, the elastic sheet 23 also has a third accommodating groove 231, and the second spring 4 is disposed in the third accommodating groove 231. Specifically, taking a circular constriction as an example, multiple elastic sheets 23 are wrapped around to form a circular constriction. When the third accommodating grooves 231 on multiple elastic sheets 23 are spliced together, they will also form a circle, and the second spring 4 is wound in the third accommodating groove 231. In this embodiment, the second spring 4 is in the shape of an elongated strip and can be wound in multiple layers in the third receiving groove 231 to enhance the positive force between the elastic sheet 23 and the external pin and improve the current conduction effect between the external pin and the conductor 2 .

[0042] Refer to it again Figure 7-Figure 9 As shown, Figure 7 for Figure 2 Enlarged view of part A in the middle; Figure 8 is a schematic diagram of the three-dimensional structure of the first reed 3; Figure 9 This is a front view of the first spring 3. The first spring 3 is a hollow structure, which can be understood as being sleeved onto the outer surface of the mounting post 22. The first spring 3 has multiple inner ridges 31 and multiple outer ridges 32. The multiple inner ridges 31 are connected to the multiple outer ridges 32. The multiple inner ridges 31 are convex inward and abut against the outer surface of the mounting post 22, while the multiple outer ridges 32 are convex outward and abut against the inner wall of the first receiving groove 11. Current can be conducted between the inner wall of the second receiving groove 12, the inner ridges 31, the outer ridges 32, and the mounting post 22. In this embodiment, both ends of the inner ridges 31 are connected to the outer ridges 32 to increase the conduction points between the mounting post 22 and the inner wall of the second receiving groove 12, thereby improving current conduction efficiency.

[0043] Specifically, the first reed 3 is made of a material with high conductivity and high yield strength, such as copper. The second reed 4 can also be made of a material with high conductivity and high yield strength; of course, the second reed 4 can also be made of stainless steel.

[0044] In summary, when the external pin is inserted into the receiving chamber 21, the connector 1, conductor 2, and first spring 3 are electrically connected, i.e., they can conduct current. The connector 1 and conductor 2 are detachably connected via the locking member 5. When the conductor 2 becomes damaged and needs to be replaced, the locking member 5 can be removed by simply removing the locking member 5. Similarly, a new conductor 2 can be replaced and the locking member 5 can be installed. This method greatly improves the efficiency of replacing the conductor 2, shortens the replacement time, reduces maintenance costs, and improves the convenience of using the connection terminal.
