Description

Technical Field

[0001] The utility model relates to a quick fixing structure of a contactor, in particular to a pre-installation structure of a contactor and a contactor. Background Art

[0002] The rapid disassembly and assembly of contactor components is crucial in production and operation maintenance. Unstable installation may cause electrical problems, such as poor or unstable circuit connections, and even affect the normal operation of the equipment. In addition, unstable installation may accelerate the wear of the contactor, resulting in a shortened equipment life and increased maintenance frequency. Therefore, the correct and stable installation of the contactor has an important impact on the stability, reliability and life of the equipment, ensuring the normal operation of the equipment.

[0003] In the prior art, the pre-installation of the contactor housing is usually performed by inserting a connector into the mounting holes arranged around it. The connector is usually a connecting rod with a limiting hole. When the connecting rod is sleeved in the mounting holes on the two shells, the pin is inserted into the limiting hole to fix the two shells. In order to prevent shaking between the shells, a spring is usually arranged outside the connecting rod.

[0004] However, the above scheme has the following shortcomings: since a spring is provided on the outer sleeve of the connecting rod, when the pin does not cooperate with the limiting hole, the spring will move the connecting rod away from the mounting hole, which makes it difficult to realize automated assembly and can only be assembled manually; and the large number of parts will not only further increase the difficulty of installation, but also cause excessively high production costs. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a quick fixing structure of a contactor which is convenient for assembly.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a quick fixing structure of a contactor, comprising a first shell, a plurality of mounting holes are provided on the first shell, and also comprising a connecting member and a spring installed in cooperation with the mounting holes, the connecting member comprising a rod portion, a first limiting portion arranged at the upper end of the rod portion, the spring is sleeved on the rod portion and cooperates with the first limiting portion and the bottom of the mounting hole to abut, the connecting member is rotatably arranged in the mounting hole, a second limiting portion is provided at the lower end of the rod portion, a through hole is provided at the bottom of the mounting hole, when the connecting member is rotated to a specific position, its second limiting portion can pass through the through hole, and at other rotation positions, the second limiting portion cooperates with the first shell to limit.

[0007] The beneficial effect of the utility model is that the second limiting portion of the connecting piece can only be extended out of the through hole when and only when it is rotated to a position corresponding to the through hole; then the connecting piece is rotated to rotate the second limiting portion to a position that is not in the through hole, and the second limiting portion is clamped on the first shell by a spring, thereby completing the limiting between the connecting piece and the first shell, so as to prevent the connecting piece from falling off from the first shell during automated assembly, thereby making assembly more convenient.

[0008] Furthermore, the first shell is provided with at least one groove which cooperates with the second limiting portion for positioning.

[0009] When the second limiting portion passes through the through hole and rests against the first shell, it may rotate due to factors such as vibration, thereby rotating the second limiting portion back to the through hole; therefore, after the groove is set, a limiting position can be provided, and when the second limiting portion is located in the groove, it will not rotate due to external factors, so as to further ensure that the connecting part will not be displaced during the assembly process.

[0010] Furthermore, the connecting piece is integrally formed.

[0011] Compared with the prior art, the connector manufactured by integral molding reduces the number of parts and components, thereby reducing production costs.

[0012] Furthermore, a connecting portion is provided on the first limiting portion.

[0013] The connecting portion is used to cooperate with an external twisting tool to facilitate the rotation of the connecting piece. The shape of the connecting portion can be a cross groove, a straight groove, etc., so as to facilitate the operation and assembly with existing tools.

[0014] Furthermore, the first shell is provided with a mark for indicating the rotation direction of the connecting member in the mounting hole.

[0015] The mark is used to indicate that the connector rotates from the through hole to the groove, and the left and right sides of the mark can be marks indicating unlocking and locking respectively, and an indicator line indicating the rotation direction can be set between the two. For convenience, the mark can also be set with an angle difference between the through hole and the groove for easy assembly and subsequent maintenance.

[0016] The utility model also provides a contactor which is convenient to assemble.

[0017] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a contactor, comprising a first shell, a second shell and a connecting piece inserted into the mounting holes on the first shell and the second shell, the connecting piece is provided with a spring, the connecting piece comprises a rod portion and a first limiting portion arranged at the upper end of the rod portion, the spring is sleeved on the rod portion and cooperates with the first limiting portion and the bottom of the mounting hole, the connecting piece is rotatably arranged in the mounting holes of the first shell and the second shell, the bottom of the mounting hole of the second shell is provided with a through hole, when the connecting piece is rotated to a specific position, its second limiting portion can pass through the through hole, and in other rotation positions, the second limiting portion cooperates with the second shell to fix the first shell and the second shell.

[0018] Furthermore, the first shell is provided with at least one groove which cooperates with the second limiting portion for positioning.

[0019] Furthermore, the connecting piece is integrally formed.

[0020] Furthermore, a connecting portion is provided on the first limiting portion.

[0021] Furthermore, the first shell is provided with a mark for indicating the rotation direction of the connecting member in the mounting hole.

[0022] The beneficial effect of the utility model is that: the connecting piece passes through the mounting holes set on the first shell and the second shell, and when and only when the connecting piece is rotated to a position corresponding to the mounting hole on the second shell, the connecting piece can be passed out of the second shell, and then the connecting piece is rotated to make the position of the second limiting part staggered with the position of the through hole, and the second limiting part can be pressed against the second shell by the spring to complete the fixation between the first shell and the second shell.
