Description

Technical Field

[0001] This utility model belongs to the field of current sensing connector technology, specifically a highly stable open / closed current sensing connector. Background Technology

[0002] A current sensing connector is a special connector that integrates current sensing functionality. It is mainly used to monitor the current value in a circuit in real time, ensuring the safe operation and efficient management of the power system. It achieves accurate measurement of current through a built-in current sensor and transmits the data to external devices for analysis or control.

[0003] In existing current sensing connectors, the external port connects to the circuit during use, and the internal electronic components are used to open and close the circuit and measure the current value. However, when the male and female terminals of the connector are connected, the clamping force generated by the snap-fit ​​keeps the male and female terminals together. As a result, when the connected circuit is accidentally pulled, the connection may separate, leading to instability in the circuit connection. Therefore, improvements are needed. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a highly stable switch-off current detection connector.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a highly stable switching current detection connector, comprising a connector, wherein a snap-fit ​​component is provided inside the connector, and a fixing structure is provided on the outside of the connector;

[0006] The snap-fit ​​assembly includes a connecting rod and a mounting rod. The outer sides of both the connecting rod and the mounting rod are connected to the inner wall of the connector. A locking block is provided on the outer surface of the connecting rod, and the outer side of the locking block extends to the outside of the connector. A connecting frame is provided on the outer surface of the mounting rod, and an inclined block is provided on the outer side of the connecting frame. The bottom of the inclined block is movably connected to the outer side of the locking block. An mounting block is provided on the outer side of the connecting frame, and the outer side of the mounting block is connected to a fixed structure.

[0007] Preferably, the connector has a male terminal on its outer side and a relay inside the connector.

[0008] Preferably, a spring is provided on the outer side of the card block, and the outer side of the spring is connected to the inner wall of the connector.

[0009] Preferably, a second spring is provided on the outer side of the connecting frame, and the outer side of the second spring is connected to the inner wall of the connector.

[0010] Preferably, four card blocks are provided, and the four card blocks are distributed on the outside of the public terminal.

[0011] Preferably, the fixing structure includes bolts, the inner sides of which extend into the inner cavity of the connector and are movably connected to pressure blocks.

[0012] Preferably, the outer surface of the pressure block is movably connected to the inner wall of the connector, and the outer side of the pressure block is provided with an inclined surface.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model is equipped with a locking block and a connecting frame. By rotating the bolt, the pressure block is driven to squeeze the mounting block, which in turn drives the connecting frame to move on the mounting rod. The inclined block squeezes the four locking blocks inward, so that they are used to lock the connection between the male and female ends of the connector, thereby further strengthening the connection between the ports, preventing displacement and pulling that could cause disconnection, avoiding unstable signal transmission, and bringing convenience to the operator.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figures 1 to 5 As shown, this is the first embodiment of the utility model, which provides a highly stable switching current detection connector, including a connector 1, a snap-fit ​​component 2 inside the connector 1, and a fixing structure 3 on the outside of the connector 1.

[0024] The snap-fit ​​assembly 2 includes a connecting rod 201 and a mounting rod 203. The outer sides of both the connecting rod 201 and the mounting rod 203 are connected to the inner wall of the connector 1. A snap-fit ​​block 202 is provided on the outer surface of the connecting rod 201, and the outer side of the snap-fit ​​block 202 extends to the outside of the connector 1. A connecting frame 204 is provided on the outer surface of the mounting rod 203. An inclined block 205 is provided on the outer side of the connecting frame 204. The bottom of the inclined block 205 is movably connected to the outer side of the snap-fit ​​block 202. An mounting block 208 is provided on the outer side of the connecting frame 204, and the outer side of the mounting block 208 is connected to the fixing structure 3.

[0025] The mounting block 208 is pressed by the rotating fixing structure 3, which in turn drives the mounting block 208 to move forward. The mounting block 208 drives the inclined block 205 to move forward, which in turn drives the locking block 202 on the connecting rod 201 to move inward. The locking block 202 locks the male end and the female end of the connector 1 together, so that they are firmly connected together. This prevents the connector 1 from being accidentally pulled during connection, which could lead to disconnection or unstable connection, and brings convenience to the operator.

[0026] Example 2

[0027] like Figure 2 and Figure 3 As shown, this embodiment includes the features of embodiment 1, the distinguishing technical feature being that a male terminal is provided on the outside of connector 1, and a relay is provided inside connector 1;

[0028] The male terminal is used to connect to external lines to ensure a stable connection. At the same time, when an abnormal current is detected or the circuit needs to be disconnected, the relay controls the coil of the electromagnetic relay to be energized or de-energized, causing the relay contacts to close or open, thereby realizing the circuit opening or closing.

[0029] Among them, a spring 206 is provided on the outside of the card block 202, and the outside of the spring 206 is connected to the inner wall of the connector 1;

[0030] At this time, since the spring 206 is in a stretched state, it will apply outward pressure to the locking block 202, thereby moving the locking block 202 away from the outside of the male end, so as to avoid the locking block 202 being obstructed when plugging in the wire and prevent affecting the installation.

[0031] Among them, a second spring 207 is provided on the outside of the connecting frame 204, and the outside of the second spring 207 is connected to the inner wall of the connector 1;

[0032] At this time, since spring 207 is in a compressed state, it will apply backward pressure to the connecting frame 204. Then, when the fixing structure 3 releases its obstruction to the connecting frame 204, the spring force of spring 207 will drive the inclined block 205 to move backward, thereby releasing the obstruction of the locking block 202 by the inclined block 205. Thus, the locking block 202 will be reset by the spring force of spring 1 206, which will facilitate subsequent use.

[0033] There are four card blocks 202, and the four card blocks 202 are published on the outside of the public terminal;

[0034] Four locking blocks 202 are used to secure the male end of connector 1, making it more secure and preventing separation when pulled.

[0035] Example 3

[0036] like Figure 3 and Figure 4 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the fixing structure 3 includes bolts 301, and the inner side of each bolt 301 extends into the inner cavity of the connector 1 and is movably connected to a pressure block 302.

[0037] By rotating the bolt 301, the pressure block 302 is moved by the pressure block 302, which in turn presses the mounting block 208, causing the four locking blocks 202 to reinforce the connection between the male and female ends and prevent accidental separation.

[0038] The outer surface of the pressure block 302 is movably connected to the inner wall of the connector 1, and the outer side of the pressure block 302 is provided with a slope.

[0039] When the bolt 301 rotates, the pressure block 302 is limited by the inner wall of the connector 1, so as to prevent the pressure block 302 from shifting position when moving, and avoid the pressure block 302 from being unable to align with the mounting block 208.

[0040] Working principle and usage process of this utility model:

[0041] First, when the operator uses connector 1, by connecting the male and female ends, rotating bolt 301 causes pressure block 302 to move inward, pressing against mounting block 208. This causes connecting bracket 204 to move on the outer surface of mounting rod 203. Simultaneously, inclined block 205 presses and causes four locking blocks 202 to move on the outer surface of connecting rod 201. The mounting rod 203 and connecting rod 201 limit the connecting bracket 204 and locking blocks 202, preventing positional displacement. The four locking blocks 202 are used to lock into the port connection, making the connection between the male and female ends more secure. This prevents connector 1 from being displaced or pulled during use, which could lead to unstable connection or disconnection, thus providing convenience for the operator.
