Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a wire crimp connector. Background Technology

[0002] An IDC connector is an electronic component that can quickly achieve electrical connection without stripping the insulation layer of the wire. Its core principle is that the connector's sharp contacts pierce the insulation layer of the wire under pressure, directly forming a mechanical and electrical connection with the conductor.

[0003] Traditional wire-pressing sensors require inserting the wire strip between the connector and the wire-pressing cover, then clamping them together with clamps to allow the connector's sharp contacts to sequentially penetrate the corresponding circuits. However, the wire strip lacks a pre-positioning point between the connector and the wire-pressing cover, which can easily cause the wire strip to shift position when the connector and the wire-pressing cover are squeezed, affecting the contacts' penetration into the corresponding circuits. Therefore, a wire-pressing connector is needed to solve the above problems. Utility Model Content

[0004] To overcome the aforementioned technical problems, the purpose of this utility model is to provide a wire-pressing connector to solve the problem mentioned in the background art that when using a traditional wire-pressing sensor, it is necessary to insert the wire strip between the connector and the wire-pressing cover, and then use clamps to clamp the two together so that the sharp contacts of the connector can be inserted into the corresponding lines in sequence. However, the wire strip lacks a pre-position between the connector and the wire-pressing cover, which makes it easy for the wire strip to shift position when the connector and the wire-pressing cover are squeezed, affecting the insertion of the contacts into the corresponding lines.

[0005] This utility model provides the following technical solution: a wire connector, including a connector base with sharp contacts and a wire cover with a corrugated groove, wherein the connector base and the wire cover are used to press and fix the cable end by protrusion pressing and locking; The corrugated groove of the pressure cap has a strip-shaped through hole that is opposite to the gap between the sharp contact points of the upper and lower layers, and a rubber strip is connected in the strip-shaped through hole; The rubber strip is elastic and presses the cable end into the corrugated groove; It also includes a shielding mechanism placed on the connector.

[0006] To achieve the above technical solution, a rubber strip and a corrugated groove are located on both sides of the ribbon cable. The rubber strip itself is elastic, which presses the ribbon cable tightly in the corrugated groove and prevents it from shifting. Compared with the prior art, this device can perform pre-positioning work before the ribbon cable sheath is pierced by sharp contacts, thus avoiding ribbon cable shifting and causing sharp contact errors.

[0007] As a further improvement to this utility model, the rubber strip has a strip-shaped groove on the pressure side that is adapted to the surface of the cable.

[0008] The above technical solution improves the pre-fixation capability of the rubber strip for the cable.

[0009] As a further improvement to this utility model, the pressure cover is also provided with a locking groove.

[0010] The above technical solution facilitates the passage of the rear area of ​​the cable end through the slot.

[0011] As a further improvement to this utility model, the shielding mechanism includes two shielding covers distributed at both ends of the connecting seat to shield the interface between the connecting seat and the pressure cover.

[0012] The above technical solution provides shielding protection at the connection point.

[0013] As a further improvement to this utility model, the two shielding covers and the connecting seat are integrally formed components.

[0014] The above technical solution improves the connection strength between the shield and the connector.

[0015] As a further improvement to this utility model, only one of the shielding covers has a marking area on its surface.

[0016] Implementing the above technical solution makes it easier to determine the connection direction of the ribbon cable.

[0017] The technical effects and advantages of this utility model are as follows: 1. This utility model uses a rubber strip and a corrugated groove on both sides of the ribbon cable. The rubber strip itself is elastic, which presses the ribbon cable tightly in the corrugated groove and prevents it from shifting.

[0018] 2. Compared with the prior art, this device can perform pre-positioning work before the cable sheath is pierced by sharp contacts, thus avoiding cable misalignment and incorrect contact of sharp contacts. Attached Figure Description

[0025] Example: Referring to the accompanying drawings, this utility model provides a wire crimping connector that achieves rapid crimping and stable connection of ribbon cables through the synergistic effect of an elastic rubber strip and sharp contacts. Its core structure and usage process are as follows: In the connecting mechanism 100 The connector 110 is injection molded with PA66 + 30% glass fiber. Several sharp contacts 1010 are distributed on the surface. The bottom of the contacts is integrally molded with the terminal block (to ensure continuous conductivity). The connector 110 has extrusion protrusions on both sides for locking and fixing with the wire clamping cover 111. The wire clamping cover 111 is fastened to the connector 110. The material is the same as that of the connector 110. A corrugated groove 1011 (to adapt to the diameter of the ribbon cable) is opened at the wire clamping point. At the same time, a slot 113 for the ribbon cable to pass through is also opened on the wire clamping cover 111. A strip-shaped through hole is reserved at the corrugated groove 1011, and a rubber strip 112 is connected in the through hole. The rubber strip 112 is made of nitrile rubber and its length is adapted to the wire pressing cover 111. A strip-shaped groove (the spacing matches the corrugated groove 1011) is opened on the wire pressing side of the rubber strip 112 to fit the surface of the ribbon cable (increasing the contact area and preventing the ribbon cable from slipping).

[0026] In the shielding mechanism 200 There are two shielding covers 210 (distributed at both ends of the length of the connector 110), which are integrally injection molded with the connector 110 (material is the same as the base), and are in the shape of "L". After the connector 110 and the wire clamping cover 111 are fastened together, they completely cover the interface gap (to prevent dust and electric shock). Meanwhile, only one side of the shield 210 has a marking area 211 on its surface for printing polarity markings (such as "+", "-" or pin numbers) to avoid reverse wiring.

[0027] The specific wire connection process is as follows: pre-installed ribbon cable Manually pull up the rubber strip 112 of the wire clamping cover 111 (using elastic deformation), put the end of the ribbon cable into the corrugated groove 1011, and ensure that the core wire of the ribbon cable is aligned with the crest of the corrugated groove 1011. Release the rubber strip 112, and after its elastic reset, it will press the ribbon cable into the corrugated groove 1011 through the strip groove (initial fixation to prevent the ribbon cable from shifting during crimping).

[0028] Fastening and locking Align the wire clamping cap 111 with the connector 110, so that the pressing protrusion is embedded into the corresponding slot to complete the initial locking (at this time, the sharp contact 1010 is in contact with the cable sheath but has not penetrated).

[0029] Clamping Fixation Use a special crimping tool to continuously press the snap-fit ​​area of ​​the connector 110 and the crimping cover 111 until the sharp contact 1010 is fully inserted into the ribbon cable sheath and makes tight contact with the core wire.
