Description

Technical Field

[0001] The utility model relates to the technical field of electrical connection, and particularly relates to a connection terminal block. Background Art

[0002] There are various types of electronic products, and various connection terminals are required to transmit electric power or electrical signals. Therefore, it is important to ensure the reliability of the connection terminals. For example, after a sensor is processed, performance testing is required. When the sensor is connected to a testing device, a metal connection terminal (pin) is usually used to connect the circuit.

[0003] In the prior art, a metal connection terminal is inserted into a corresponding socket to connect to an external device such as a testing device. As Figure 1 shown, two clamping pieces 102 that are in contact with each other or have a very small gap are provided in the socket 101 of the external device. When the metal connection terminal is inserted into the socket 101, the two clamping pieces 102 are in contact with and fixed to the metal connection terminal to achieve electrical connection. However, in the long-term and frequent use of the above-mentioned socket 101, the two clamping pieces 102 are prone to wear, resulting in an increase in the gap between them, poor contact with the metal connection terminal, poor testing effect and short service life.

The first grooves 21 are rectangular, and 4 fixed electrical connectors 4 are arranged along their length direction L and are respectively fixed in the 4 first grooves 21. The second groove 22 is also rectangular. The second groove 22 is connected to the first grooves 21 along the length direction L, and the depth of the second groove 22 is greater than the depth of the first grooves 21.

[0030] The fixed electrical connector 4 and the movable electrical connector 5 are limited by the first groove 21 and the second groove 22 respectively, and the relative positions between the two are fixed. Moreover, the second groove 22 can limit the displacement range of the movable electrical connector 5 to ensure that the movable electrical connector 5 can approach and abut against the fixed electrical connector 4 in a predetermined direction, that is, the length direction L. In this embodiment mode, when the movable electrical connector 5 moves along the length direction L to abut against the first groove 21, an insertion interface 6 for electrical connection with an external terminal is formed between the movable electrical connector 5 and the fixed electrical connector 4.

[0031] Preferably, in the present embodiment, the size of the fixed electrical connector 4 matches the first groove 21. The fixed electrical connector 4 further includes a connection groove 41 formed at one end of the fixed electrical connector 4 close to the movable electrical connector 5. The connection groove 41 opens towards the second groove 22 along the length direction L. When the movable electrical connector 5 moves along the length direction L to abut against the first groove 21, the movable electrical connector 5 abuts against the fixed electrical connector 4 in a form of inserting into the connection groove 41. The connection groove 41 can define the abutting position between the fixed electrical connector 4 and the movable electrical connector 5, ensuring that the external terminal can be stably clamped between the fixed electrical connector 4 and the movable electrical connector 5, and improving the stability of the electrical connection between the external terminal and the connection terminal block 1.

The movable electrical connector 5 is movably arranged in the second groove 22, and the spring 3 can drive the movable electrical connector 5 in the second groove 22 along the length direction L. The spring 3 and the movable electrical connector 5 can be fixed by means such as bonding and welding, or the spring 3 can be arranged in a state of maintaining a certain tension to abut.

[0037] As Figure 4As shown, in the embodiment of the present utility model, the connection terminal block 1 further includes a groove cover 7 covering the second groove 22. A plurality of second grooves 22 are arranged in parallel. One end of the movable electrical connector 5 and the spring 3 in contact with each other, as well as the spring 3, are arranged in the second groove 22. The groove cover 7 can cover a plurality of second grooves 22 at one time, playing roles such as protecting and dust-proofing the components in the plurality of second grooves 22. Moreover, the uniformly covered groove cover 7 is also more convenient and faster during assembly and maintenance.

[0038] Preferably, in the embodiment of the present utility model, the fixed electrical connector 4 further includes a wiring terminal 42 arranged at one end of the fixed electrical connector 4 away from the movable electrical connector 5.

[0042] In the embodiment of the present utility model, an insertion interface 6 is formed between the fixed electrical connector 4 and the movable electrical connector 5 of the connection terminal block 1. When the 4 metal connection pins 201 of the external terminal 200 are respectively inserted into the 4 insertion interfaces 6, the position of the fixed electrical connector 4 on one side of the insertion interface 6 remains fixed. The metal connection pin 201 gives the movable electrical connector 5 a force in a direction away from the fixed electrical connector 4. The movable electrical connector 5 moves along the length direction L towards the fixed electrical connector 4 and close to the spring 3 side. The spring 3 is squeezed to form a force in the opposite direction to make the movable electrical connector 5 close to the fixed electrical connector 4, so that the fixed electrical connector 4 and the movable electrical connector 5 can tightly clamp the metal connection pins 201 of the external terminal 200, ensuring stable electrical connection of the external terminal 200. Moreover, compared with the existing solution that relies on the deformation of the clamping part itself for clamping and fixing, in this embodiment, the force for clamping and fixing the external terminal 200 is provided by the deformation of the spring 3, which can greatly reduce the wear and consumption of the clamping parts, namely the fixed electrical connector 4 and the movable electrical connector 5 itself, and extend the service life of the entire connection terminal block 1.
