Detailed Description

As shown in fig. 1-4, a connector structure comprises a clip body 1, an operating handle 2, a clamping member 3 and a conductive member 4, wherein the clip body 1 is provided with an insertion hole 5 and a connection hole 6 for inserting a wire, the insertion hole 5 is arranged on two opposite sides of the clip body 1, an inner cavity chamber 7 communicated with the insertion hole 5 is arranged between the insertion holes 5, and the conductive member 4 and the clamping member 3 are arranged in the inner cavity chamber 7. The connecting hole 6 is convenient for the connector to connect and is a permanent hole. The insertion hole 5 is used for facilitating the insertion of two wires from different directions and is indirectly electrically connected through the conductive member 4. The inner cavity chamber 7 is arranged between the jacks 5 and is communicated in sequence, and the inner cavity chamber 7 mainly contains main components.

The conductive piece 4 is sequentially provided with a fixed end 8, a slow resistance part 9 and a butting part 10 from two ends to the center, the clamping piece 3 is provided with a positioning end 11 and a pressing part 12, and the fixed end 8 is fixedly assembled with the cavity wall of the inner cavity chamber 7. The fixing end 8 is used to fix the conductive member 4, and the buffer portion 9 is used to prevent the wire from being inserted too much.

An inserting groove 13 for inserting the lead is formed between the slow stopping part 9 and the inner cavity chamber 7, and the part of the inserting groove 13 is communicated with the inserting hole 5 to form a relatively limited space.

The clamping piece 3 is made of an elastic element, and the operating handle 2 and the clamp body 1 are movably assembled to form a rotating pair. The actual materials of the clamping part 3 are various and are not explained or limited herein. The operating handle 2 is mainly arranged to rotate, and is a common technical means in the field.

The clamping member 3 and the conductive member 4 have an initial state and a clamped state therebetween. When the initial state is switched to the clamping state, the operating handle 2 presses the clamping piece 3 downwards through rotation, and the clamping piece 3 sequentially presses the conductive piece 4 and the lead to be attached to each other. The space of the clamping member 3 is compressed by the rotation of the operating handle 2, and the clamping member 3 is deformed by compression. At the same time, the clamping member 3 gradually presses the conductive member 4 and the wire again by an elastic restoring force. Finally, the conductive member 4 and the wall of the lumen 7 together provide a direct clamping force on the wire.

The shape of the pressing part 12 of the clamping piece 3 corresponds to the shape of the slow resistance part 9 and the abutting part 10 of the conductive piece 4, and the slow resistance part 9 is of an arc-shaped structure. The arc-shaped structure is convenient to produce, improves the production efficiency, and has a better deformation-preventing effect when being pressed. The shape of the pressing part 12 corresponds to the shape of the pressing position on the conductive piece 4, so that the pressing part is convenient to fit and the service life is prolonged.

When in a clamping state, the abutting part 10 abuts against the cavity wall of the inner cavity chamber 7, so that the damage to the internal structure of the clamp body 1 caused by excessive insertion or direct contact of two wires is avoided.

The conducting piece 4 is provided with a positioning groove for the positioning end 11 of the clamping piece 3 to pass through, and the limiting direction of the positioning end 11 inserted into the positioning groove is the same as the direction of the wire inserted into the jack 5, so that the clamping piece 3 is prevented from being separated from the conducting piece 4, and the structural stability is maintained.

The side cross-section projection of the pressing part 12 is annular, so that the deformation capacity is improved.

The cavity wall of the inner cavity chamber 7 is provided with a limit groove 14 which is matched with the abutting part 10 for limiting, namely, the abutting part of the inner cavity chamber 7 and the abutting part 10 is a sunken groove, so that the abutting part 10 has a certain embedding limiting effect.

The fixing hole 15 is formed in the cavity wall of the inner cavity chamber 7, the fixing end 8 of the conductive piece 4 is inserted into the fixing hole 15 to be limited and fixed, the fixing hole 15 can be hook-shaped or wavy, the shapes of the fixing hole 15 are various, the shape of the fixing end 8 can be changed accordingly, the fixing effect is improved, and the description and the limitation are not excessive.

The clamp body 1 comprises a clamping cover 16 and a base 17, and the clamping cover 16 and the base 17 are fixedly assembled. The clamp body 1 is of a split structure, so that the components are convenient to assemble and disassemble, and the replacement and the disassembly are also convenient. The fixing assembly between the card cover 16 and the base 17 can be a clamping fixing or other fixing method, which is not described in detail herein.

The clamp body 1 is provided with a cutting groove 18, the operating handle 2 is arranged at the cutting groove 18, and the operating handle 2 and the groove wall of the cutting groove 18 are blocked and limited. The rotation angle of the operating handle 2 is limited by the cutting groove 18, so that the looseness of the inserted and clamped wires is avoided, and the clamping effect is ensured.
