Description

Technical Field

[0001] This utility model relates to the field of connector terminal technology, specifically to a connector terminal with a short-circuit prevention structure. Background Technology

[0002] A terminal block, also known as a wiring terminal, is an accessory used to achieve electrical connections. It is a metal strip encased in insulating plastic, with holes at both ends for inserting wires. Tools (such as screwdrivers or crimping pliers) are used to connect the two points together. Terminal blocks are an indispensable basic component in electrical connections.

[0003] The prior art (Chinese Patent No. CN214849142U, Publication Date: 2021-11-23) discloses a novel connector terminal, comprising multiple first terminals; each first terminal is provided with multiple protrusions, the protrusions on adjacent first terminals are staggered vertically, and the protrusions of the next first terminal of the two adjacent first terminals are coaxial with the protrusions of the first first terminal of the two adjacent first terminals. The vertical spacing between the protrusions of adjacent first terminals is 0.10 mm or more. The terminal body includes a fixing part, a first connecting arm, and a second connecting arm. The fixing part is integrally formed with the first connecting arm through a bending part, and the first connecting arm is integrally formed with the second connecting arm through an arc-shaped part. By arranging the protrusions of adjacent first terminals vertically, the problem of stress concentration in the terminal can be effectively solved, thereby improving the performance of the terminal; by providing the corresponding bending part in the terminal, the yield problem of the terminal can be effectively improved.

[0004] While existing connector terminals can improve terminal performance and effectively address the yielding problem, overlap may occur between the stamped pre-broken metal wires in the connector terminals. When the metal overlaps at the pre-broken positions of two adjacent pin terminals, it causes a short circuit, ultimately leading to functional failure, and in severe cases, it can cause the machine to burn out.

[0005] Therefore, we propose a connection terminal with a short-circuit prevention structure to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a connection terminal with a short-circuit prevention structure to solve the problem that the stamped pre-broken metal wires in the connection terminal mentioned in the background art may overlap. When the metal overlaps at the pre-broken positions of two adjacent pin terminals, a short circuit is caused, which eventually leads to functional failure and, in severe cases, burns out the machine.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a connection terminal with a short-circuit prevention structure, including a docking base housing, a docking flip-top housing on the upper surface of the docking base housing, a terminal body between the docking base housing and the docking flip-top housing, and a segmented pre-break structure on the side of the terminal body, which can shorten the effective length of the material pulling through the segmented pre-break structure.

[0008] Furthermore, both the docking base housing and the docking flip-top housing have terminal docking grooves on their inner sides, and the terminal body is nested and inserted into the inside of the terminal docking groove.

[0009] Furthermore, the terminal mating slots are arranged at equal intervals inside the mating base housing and the mating flip-top housing.

[0010] Furthermore, the side end of the terminal body is provided with a pre-broken metal wire, and the position of the terminal body corresponds one-to-one with the terminal mating groove.

[0011] Furthermore, the segmented pre-break structure includes a transverse segment and a through pre-break, and the segmented pre-break structure is through pre-break on the side of the terminal body.

[0012] Furthermore, the transverse segment and the through pre-cut portion are arranged in a cross shape along the side end of the terminal body. The length of the transverse segment is less than the maximum length of the through pre-cut portion, and the length of the transverse segment is the same as the thickness of the terminal body.

[0013] Furthermore, the transverse segment and the through pre-cut section cooperate to shorten the length of the stamping pre-cut metal wire.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the end side of the terminal body is provided with a segmented pre-break structure, which adopts a two-segment structure, which can shorten the effective length of the pulling material and avoid short circuit caused by excessively long metal wires, so that even if a metal wire does appear, it will not cause a short circuit.

[0015] 1. The terminal body can be inserted into the docking base housing and the docking flip housing through the terminal mating groove, thereby quickly assembling the connector terminals.

[0016] 2. The terminal body is provided with a segmented pre-break structure on the end side. The segmented pre-break structure can shorten the length of the stamped pre-break metal wire in the structure. Even if the stamped pre-break metal wire is actually present, the length of the stamped pre-break metal wire on both sides is relatively short and there will be no overlap, thereby further preventing the occurrence of short circuit.

[0017] 3. The segmented pre-break structure can be segmented by the transverse segmentation section. The through pre-break section can be segmented by the transverse segmentation section. When the stamped pre-break metal wire appears, the transverse segmentation section and the through pre-break section cooperate with each other to shorten the length of the stamped pre-break metal wire. This avoids the stamped pre-break metal wires on adjacent terminals from overlapping, causing short circuits and ultimately leading to functional failure.

[0018] 4. The segmented pre-cut structure adopts a two-segment structure, which can shorten the effective length of the material and avoid short circuits caused by excessively long metal wires. Attached Figure Description

The terminal body 3 is nested and inserted into the interior of the terminal mating groove 2. The terminal mating grooves 2 are arranged at equal intervals with respect to the interior of the mating base housing 1 and the mating flip-top housing 4. A stamped pre-broken metal wire is provided on the side end of the terminal body 3, and the position of the terminal body 3 corresponds one-to-one with the terminal mating groove 2.

[0028] The terminal body 3 can be inserted into the docking base housing 1 and the docking flip housing 4 through the terminal docking groove 2, thereby quickly assembling the connector terminals.

[0029] Example 2: Figure 3 , Figure 4 , Figure 5 and Figure 6 The technical solution shown is provided by the present utility model as follows: A connection terminal with a short-circuit prevention structure, which discloses a segmented pre-break structure 5. The segmented pre-break structure 5 can shorten the effective length of the material pulling and avoid short circuit caused by excessively long metal wires. The segmented pre-break structure 5 is provided on the side of the terminal body 3. The segmented pre-break structure 5 can shorten the effective length of the material pulling. The segmented pre-break structure 5 includes a transverse segment 6 and a through pre-break 7. The segmented pre-break structure 5 is through pre-break on the side of the terminal body 3. The transverse segment 6 and the through pre-break 7 are arranged in a "+" shape along the side of the terminal body 3. The length of the transverse segment 6 is less than the maximum length of the through pre-break 7. The length of the transverse segment 6 is the same as the thickness of the terminal body 3. The transverse segment 6 and the through pre-break 7 cooperate to shorten the length of the stamped pre-break metal wire.
