Description

Technical Field

[0001] The present invention relates to the technical field of cable connection, and particularly to a push-in terminal and a wire assembly. Background Art

[0002] A printed circuit board is a carrier for electrical interconnection of electronic components. There are numerous printed conductors on its surface. The printed conductors are connected to other external electronic components through external wires to achieve electrical control. In some usage scenarios with high requirements for disassembly and assembly speed, alligator clips are usually installed on the external wires. The printed circuit board can be quickly clamped through the alligator clips. However, the clamping force of the alligator clips is relatively large, which is likely to scratch and damage the printed circuit board. Moreover, the operator needs to be proficient in using the alligator clips, which is not friendly to the operation practice of some minors.

[0003] Therefore, there is an urgent need for a push-in terminal and a wire assembly to improve the installation convenience of wires on the circuit board. Summary of the Invention

[0004] An object of the present invention is to provide a push-in terminal and a wire assembly to improve the installation convenience of wires on the circuit board.

[0008] A conductive terminal, inserted into the wire clamp assembly. The conductive terminal includes two symmetrically arranged elastic conductive parts. At least a part of the elastic conductive part extends into the clamping groove and inclines towards the notch of the clamping groove. When the circuit board is inserted into the clamping groove, the circuit board is located between the two elastic conductive parts, and the two elastic conductive parts are used to elastically clamp the circuit board.

[0009] As an optional technical solution, the end of the elastic conductive part close to the clamping groove is a guiding part, the guiding part is inclined, and the inclined surface of the guiding part faces the sliding direction of the circuit board.

[0010] As an optional technical solution, the elastic conductive part further includes a limiting convex bump. The limiting convex bump is located on the side of the guiding part away from the notch of the clamping groove, and the limiting convex bump is used to be inserted into the through hole of the circuit board.

[0011] As an optional technical solution, the limiting convex bump is arranged on the inclined surface of the guiding part;

[0012] Alternatively, the elastic conductive part further includes a contact part adjacent to the guiding part. The contact part is horizontally arranged, and the limiting convex hull is arranged on the horizontal plane of the contact part.

[0014] A wire clamp, the clamping groove is formed in the wire clamp, and the elastic conductive part is inserted into the wire clamp;

[0015] A mounting member is mounted at one end of the wire clamp away from the clamping groove. The conductive terminal further includes a wire connection part inserted into the mounting member, and the wire connection part is used to connect and fix a wire arranged on the mounting member;

[0016] An insulating member is arranged between the elastic conductive part and the wire, and the insulating member is used to insulate and isolate the elastic conductive part and the wire.

[0017] As an alternative technical solution, an installation groove is formed at one end of the wire clamp close to the mounting member, a guiding groove is formed in the side wall of the installation groove, and the guiding groove communicates with the clamping groove. The conductive terminal further includes a first conductive part inserted into the installation groove, a detection part extending to the guiding groove is arranged on the side wall of the first conductive part, and the LED lamp is inserted into the guiding groove from one side of the clamping groove and elastically abuts against the detection part.

[0018] As an alternative technical solution, a limiting post is arranged on one side of the guiding groove close to the clamping groove, and the limiting post is used to limit the deviation of the LED lamp towards the installation groove. The detection part is bent towards the side of the wire connection part in the guiding groove.

[0019] As an alternative technical solution, the conductive terminal further includes a second conductive part extending to the mounting member. The insulating member seals the notch of the installation groove and is located between the first conductive part and the second conductive part. The second conductive part includes a blocking part extending to the guiding groove, and the blocking part seals one end of the guiding groove close to the mounting member.

[0020] As an alternative technical solution, a limiting wall is arranged on one side of the guiding groove close to the mounting member, the blocking part abuts against the limiting wall, and the limiting wall is used to block the LED lamp from passing through the guiding groove into the mounting member.

[0021] In a second aspect, a wire assembly is provided. The wire assembly includes a wire and the push-in type terminal as described above. The two ends of the wire are respectively provided with the push-in type terminal, and one of the push-in type terminals is clamped to a circuit board, and the other push-in type terminal is inserted with an LED lamp.

By using this push - type terminal, a wire can be quickly connected to a circuit board, improving the installation convenience of the wire on the circuit board. When it is necessary to electrically connect a wire to a circuit board, push - type terminals of the present invention are respectively installed at both ends of the wire, so that the wire is electrically connected to the conductive terminal. Then, align the clamping groove of one of the push - type terminals with the circuit board, and push the circuit board into the clamping groove. Compared with using a clamping - type alligator clip, using the push - type terminal of the present invention is more labor - saving, so the installation convenience of the wire on the circuit board can be improved; when the circuit board slides into the clamping groove, the circuit board is located between two elastic conductive parts. The circuit board presses against the elastic conductive parts, and at this time, the two elastic conductive parts move away from each other. The elastic conductive parts are compressed and elastically deformed, and the two elastic conductive parts generate clamping forces with equal magnitudes and opposite directions on the circuit board, ensuring the connection stability between the push - type terminal and the circuit board.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present invention.

[0041] In the description of this specification, the description referring to terms such as "one embodiment", "example", etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example.

[0042] The technical solution of the present invention will be further described below with reference to the drawings and through specific embodiments.

[0043] As Figures 1 to 8 shown, the wire assembly provided in this embodiment includes a wire 200 and a push-in terminal 100. Push-in terminals 100 are respectively installed at both ends of the wire 200. One of the push-in terminals 100 is snap-connected to the circuit board 300, and the other push-in terminal 100 is inserted with an LED lamp 400. When one of the push-in terminals 100 is snap-connected to the circuit board 300, if the LED lamp 400 lights up, it proves that the wire 200 is electrically connected to the circuit board 300. If the LED lamp 400 does not light up, it proves that the wire 200 is not energized with the circuit board 300.

[0044] This embodiment provides a push-in terminal 100, which includes a wire clamp assembly 1 and a conductive terminal 2. A clamping groove 111 is opened at one end of the wire clamp assembly 1, and the clamping groove 111 is used to avoid the circuit board 300 or the LED lamp 400; the conductive terminal 2 is inserted into the wire clamp assembly 1. The conductive terminal 2 includes two symmetrically arranged elastic conductive parts 21. At least a part of the elastic conductive part 21 extends into the clamping groove 111 and inclines towards the notch of the clamping groove 111. When the circuit board 300 is inserted into the clamping groove 111, the circuit board 300 is located between the two elastic conductive parts 21, and the two elastic conductive parts 21 are used to elastically clamp the circuit board 300.

[0045] Specifically, the push - type terminal 100 of this embodiment can quickly connect the wire 200 to the circuit board 300, improving the installation convenience of the wire 200 on the circuit board 300. When it is necessary to electrically connect the wire 200 to the circuit board 300, the push - type terminals 100 of this embodiment are respectively installed at both ends of the wire 200, so that the wire 200 is electrically connected to the conductive terminal 2. Then, align the clamping groove 111 of one of the push - type terminals 100 with the circuit board 300, and push the circuit board 300 into the clamping groove 111 in a pushing manner. Compared with the clamping - type alligator clip, using the push - type terminal 100 of this embodiment is more labor - saving, so it can improve the installation convenience of the wire 200 on the circuit board 300. When the circuit board 300 slides into the clamping groove 111, the circuit board 300 is located between the two elastic conductive parts 21. The circuit board 300 presses against the elastic conductive parts 21. At this time, the two elastic conductive parts 21 move away from each other, and the elastic conductive parts 21 are compressed and elastically deformed. The two elastic conductive parts 21 generate clamping forces on the circuit board 300 that are equal in magnitude and opposite in direction, ensuring the connection stability between the push - type terminal 100 and the circuit board 300.

[0046] Optionally, receiving grooves 116 are provided on both the top wall and the bottom wall of the clamping groove 111. The receiving grooves 116 are used to receive the elastic conductive parts 21. When the elastic conductive parts 21 are compressed by the circuit board 300, the elastic conductive parts 21 contract into the receiving grooves 116. Since the elastic conductive parts 21 can contract into the receiving grooves 116, the height of the slot opening of the clamping groove 111 is adapted to the thickness of the circuit board 300, so as to reduce the jump gap between the circuit board 300 and the top wall or the bottom wall of the clamping groove 111.

[0047] Optionally, the end of the elastic conductive part 21 close to the clamping groove 111 is a guiding part 211. The guiding part 211 is inclined, and the inclined surface of the guiding part 211 faces the sliding direction of the circuit board 300.

[0048] When the circuit board 300 slides into the clamping groove 111, the edge of the circuit board 300 first abuts against the inclined surface of the guiding part 211 and slides on the inclined surface of the guiding part 211. At this time, the elastic conductive part 21 gradually retracts into the receiving groove 116. In this embodiment, the guiding part 211 is inclined to prevent the circuit board 300 from breaking the elastic conductive part 21.

[0049] Optionally, the elastic conductive part 21 further includes a limiting convex bump 212. The limiting convex bump 212 is located on the side of the guiding part 211 away from the slot opening of the clamping groove 111. The limiting convex bump 212 is used to be inserted into the through - hole of the circuit board 300.

[0050] When the circuit board 300 slides over the inclined surface of the guiding portion 211, the limiting convex bump 212 snaps into the through hole of the circuit board 300, and the push - type terminal 100 completes the clamping action on the circuit board 300. The limiting convex bump 212 can improve the connection stability between the circuit board 300 and the elastic conductive portion 21 in the clamping groove 111, preventing the circuit board 300 from easily detaching from the clamping groove 111. When the circuit board 300 is pulled out of the clamping groove 111, the limiting convex bump 212 provides a relatively large anti - detachment resistance. Moreover, when the limiting convex bump 212 snaps into the through hole of the circuit board 300, an elastic impact occurs. The operator holding the wire clamp assembly 1 can feel the vibration through touch or hear the impact sound of the elastic conductive portion 21 on the circuit board 300 through hearing, so as to prompt the operator to complete the clamping operation.

[0051] As Figure 8 shown, in some embodiments, the limiting convex bump 212 is arranged on the inclined surface of the guiding portion 211; as Figure 7 shown, in some other embodiments, the elastic conductive portion 21 further includes a contact portion 213 adjacent to the guiding portion 211. The contact portion 213 is horizontally arranged, and the limiting convex bump 212 is arranged on the horizontal plane of the contact portion 213. After the circuit board 300 slides over the guiding portion 211, the contact portion 213 fits with the surface of the circuit board 300, increasing the contact area and improving the current overload capacity.

[0052] Optionally, the wire clamp assembly 1 includes a wire clamp 11, a mounting member 12, and an insulating member 13. The clamping groove 111 is formed in the wire clamp 11, and the elastic conductive portion 21 is inserted into the wire clamp 11; the mounting member 12 is installed at one end of the wire clamp 11 away from the clamping groove 111. The conductive terminal 2 further includes a wire connection portion 22 inserted into the mounting member 12, and the wire connection portion 22 is used to connect and fix the wire 200 arranged on the mounting member 12; the insulating member 13 is arranged between the elastic conductive portion 21 and the wire 200, and the insulating member 13 is used to insulate and isolate the elastic conductive portion 21 and the wire 200.

[0053] The elastic conductive portion 21 in contact with the circuit board 300 is arranged on the wire clamp 11, the wire connection portion 22 in contact with the wire 200 is arranged on the mounting member 12, and the insulating member 13 is arranged between the wire clamp 11 and the mounting member 12. The insulating member 13 insulates and isolates the elastic conductive portion 21 and the wire 200, and the arcs generated by the contact between the elastic conductive portion 21 and the circuit board 300 and the arcs generated by the contact between the wire connection portion 22 and the wire 200 are blocked and isolated by the insulating member 13.

[0054] The wire connection portion 22 is arranged in an arc - shaped structure. The arc - shaped wire connection portion 22 has better connection stability with the wire 200, a larger contact area, and stronger overload capacity.

[0055] Optionally, an installation groove 112 is formed at one end of the wire clamp 11 close to the installation member 12. A guiding groove 113 is formed in the side wall of the installation groove 112. The guiding groove 113 communicates with the clamping groove 111. The conductive terminal 2 further includes a first conductive part 23 inserted into the installation groove 112. A detection part 231 extending to the guiding groove 113 is arranged on the side wall of the first conductive part 23. The LED lamp 400 is inserted into the guiding groove 113 from one side of the clamping groove 111 and elastically abuts against the detection part 231.

[0056] The conductive terminal 2 includes two symmetrically arranged elastic conductive parts 21, a wire connecting part 22 with an arc-shaped structure, a first conductive part 23 with a detection part 231 arranged on its side wall, and a second conductive part 24 with a blocking part 241 arranged on its side wall, such that the overall structure of the conductive terminal 2 is relatively large. The conductive terminal 2 can only be inserted into the wire clamp 11 from the other side far from the clamping groove 111, that is, the conductive terminal 2 can only be inserted into the wire clamp 11 from the installation groove 112. After the elastic conductive part 21 and the first conductive part 23 in the conductive terminal 2 are inserted into the wire clamp 11, the insulating part 13 is sealed at the notch of the installation groove 112. Then, the installation member 12 fixedly connecting the wire 200 is fixed to the wire clamp 11, and the pin of the LED lamp 400 is inserted into the guiding groove 113. The pin of the LED lamp 400 elastically abuts against the detection part 231 in the guiding groove 113. Whether the wire 200 is electrically connected to the circuit board 300 is distinguished by whether the LED lamp 400 lights up. The detection means is simple and accurate; the detection part 231 and the pin of the LED lamp 400 are elastically abutted, and LED lamps 400 of different specifications can be used, and the contact stability between the detection part 231 and the pin of the LED lamp 400 can be ensured.

[0057] Optionally, a limiting post 114 is arranged on the side of the guiding groove 113 close to the clamping groove 111. The limiting post 114 is used to limit the deviation of the LED lamp 400 towards the installation groove 112. The detection part 231 is bent towards the side of the wire connecting part 22 in the guiding groove 113. The LED lamp 400 is inserted into the guiding groove 113 from one side of the clamping groove 111. Therefore, the detection part 231 is bent towards the side of the wire connecting part 22 to avoid the pin of the LED lamp 400 or the detection part 231 from being broken.

[0058] Optionally, the conductive terminal 2 further includes a second conductive part 24 extending to the installation member 12. The insulating part 13 is sealed at the notch of the installation groove 112 and is located between the first conductive part 23 and the second conductive part 24. The second conductive part 24 includes a blocking part 241 extending to the guiding groove 113. The blocking part 241 seals one end of the guiding groove 113 close to the installation member 12. The pin of the LED lamp 400 is in electrical contact with the detection part 231 in the guiding groove 113. The generated electric arc is isolated and eliminated by the blocking part 241, avoiding affecting the contact between the wire connecting part 22 inside the installation member 12 and the wire 200.

[0059] Optionally, a limiting wall 115 is provided on one side of the guiding groove 113 close to the mounting member 12. The blocking portion 241 abuts against the limiting wall 115. The limiting wall 115 is used to block the LED lamp 400 from passing through the guiding groove 113 and entering the mounting member 12. When the pins of the LED lamp 400 are inserted into the bottom of the guiding groove 113, the pins of the LED lamp 400 contact the limiting wall 115. Even if an insertion force is applied to the LED lamp 400 again, the pins of the LED lamp 400 cannot pass through the limiting wall 115 and enter the interior of the mounting member 12. In some cases, if there is no limiting wall 115, the pins of the LED lamp 400 may enter the interior of the mounting member 12 after pushing open the blocking portion 241. If there is no blocking portion 241 and the limiting wall 115 completely blocks one end of the guiding groove 113 close to the mounting member 12, the detection portion 231 cannot be installed in the guiding groove 113, and the conductive terminal 2 cannot be installed in the wire clamp 11 from one side of the mounting groove 112.

[0060] In addition, the above is only the preferred embodiment of the present invention and the technical principles applied. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein. Various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention.
