Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a spring-type wiring device for connectors. Background Art

[0002] In the prior art, spring-clip wire-pressing terminal blocks are widely used. When connecting wires, the traditional spring-clip device is pressed by an auxiliary tool to open the gap between the spring-clip and the metal conductor, and the cable is loaded; when removing the wire, the spring-clip device is also pressed by an auxiliary tool to compress the end of the spring that contacts the metal conductor, and the cable is removed. After releasing the pressure, the spring-clip rebounds to its original state. During the loading and removal process, the operator is required to keep pressing the spring-clip device, which is not conducive to operation. Utility Model Content

DETAILED DESCRIPTION

[0033] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0034] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0035] like Figure 1 and Figure 2 As shown, the spring clip wiring device in this embodiment includes a conductive bracket 3, a spring clip 1, an insulating push block 2 and a pin 4, wherein the conductive bracket 3 is a groove-shaped structure as a whole, having three side surfaces, two of which are limit baffles 3-2, which limit the movement of the spring clip 1 in the horizontal direction and guide the movement of the insulating push block 2 in the vertical direction. A limit slot 3-1 is also provided in the vertical direction to prevent the insulating push block 2 from detaching from the conductive bracket 3 in the vertical direction.

[0036] like Figure 2 and Figure 3 As shown, the spring piece 1 includes a three-section structure, a locking section 1-3, a fixed section 1-1 and a floating section 1-2, wherein the locking section 1-3 has two bifurcated ends, and protrusions 1-4 are respectively arranged on the outer sides of the two ends, and the protrusions 1-4 are used to limit the spring piece. The floating section 1-2 is an end that can be elastically deformed relative to the fixed section 1-1, wherein the first bending section 1-2-1, the second bending section 1-2-2 and the third bending section 1-2-3 are bent in sequence, and the three different bending sections have different inclination angles, which can provide forces in different directions during the elastic deformation process. The end of the third bending section 1-2-3 is in close contact with the opposite side of the conductive bracket 3 in a free state. After the floating section 1-2 is subjected to external force, the third bending section 1-2-3 follows the floating section 1-2 to deform and separate from the conductive bracket 3, thereby forming a plug-in cavity that can be inserted and withdrawn.

[0037] like Figure 6 , Figure 7 The figure is a schematic diagram of the structure after the overall assembly, including an insulating housing 5, on which a plurality of independent mounting holes are provided, and a set of wiring devices can be independently installed in each mounting hole. When the conductive bracket 3 is installed in the insulating housing 5, the fixing section of the spring sheet 1 is in contact with the insulating housing 5 at the same time, and the mounting hole of the insulating housing 5 plays a role in fixing the spring sheet 1 and the conductive bracket 3. The protrusions 1-4 on the locking section 1-3 of the spring sheet 1 and the card slot on the insulating housing 5 are mutually locked, which plays a role in fixing and positioning the spring sheet 1, and prevents the entire wiring device from falling off from the mounting hole of the insulating housing 5.

[0038] In actual use, such as Figure 4 As shown, the bottom of the insulating push block 2 is in contact with the first bent portion 1-2-1 of the spring sheet 1, and the spring sheet 1 is in a free state. The end of the third bent portion 1-2-3 is in close contact with the inner side of the conductive bracket 3, and a closed state is formed between the spring sheet 1 and the conductive bracket 3. The spring sheet 1 in the free state exerts a force on the insulating push block 2 in the vertical direction, so that the limiting step 2-1 is stuck on the conductive bracket 3 to prevent the insulating push block 2 from falling off.

[0039] like Figure 5 As shown, when the insulating push block 2 is pushed downward in the vertical direction, the guide surface 2-2 moves along the first bend 1-2-1 toward the second bend 1-2-2 until the bottom of the insulating push block 2 contacts the third bend 1-2-3, and the second bend 1-2-2 and the bottom of the insulating push block 2 are in a state of being parallel to each other. The floating section 2 of the spring 1 applies a horizontal elastic force to the insulating push block 2 through the second bend 1-2-2, thereby squeezing the insulating push block 2 onto the conductive bracket 3. At the same time, the end of the third bend 1-2-3 is separated from the conductive bracket 3 due to the action of external force, and the third bend 1-2-3 and the conductive bracket 3 can be plugged or pushed.

[0040] When the wiring is completed, use a tool to pick up the locking ear 2-3 on the insulating push block 2 outside the insulating shell 5, so that the bottom of the insulating push block 2 and the second bending part 1-2-2 fall off, change the force on the insulating push block 2, make the bottom contact with the first bending part 1-2-1 again, and make the end of the third bending part 1-2-3 closely contact with the conductive bracket 3 again.

[0041] In this embodiment, the wiring device can operate on solid wires, terminal wires, and twisted wires. It can operate not only on a single cable, but also on several cables at the same time, which is convenient and quick.

[0042] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
