Description

Technical Field

[0001] The utility model relates to the technical field of contactor shells, in particular to a contactor shell convenient for installation. Background Art

[0002] A contactor is a widely used switching electrical appliance. Using electromagnetic, pneumatic or hydraulic principles, it realizes the on-off of the main circuit through a control circuit, and has the advantages of strong current-breaking ability, rapid action, safe operation, capable of frequent operation and remote control, etc.

[0003] The shell of a contactor is usually divided into an upper shell and a lower shell. After the corresponding parts are installed on the upper shell and the lower shell respectively, the upper shell and the lower shell are then installed. At present, the traditional contactor shell still uses screws to install the contactor shell. The inconvenience of this structure is that in the actual assembly process, workers usually use an automatic screwdriver to install the screws onto the contactor shell. The automatic screwdriver will operate on the screws with a relatively large force during the working process. At the same time, the contactor shell is made of plastic material, which leads to the situation that if the worker does not align the screw with the installation opening on the contactor shell, the automatic screwdriver may damage the thread at the installation opening during the process of rotating the inclined screw, and this damage is irreversible. Content of the Utility Model

[0004] The utility model provides a contactor shell convenient for installation, which solves the above problems existing in the prior art during use.

[0005] The technical solution of the utility model is realized as follows: A contactor shell convenient for installation includes an upper shell and a lower shell. Limiting buckle groups are arranged on the left and right side walls of the lower shell. Each limiting buckle group includes two limiting blocks arranged front and back and a supporting block. The limiting blocks are slidably arranged on the side wall of the lower shell in the front-back direction, and the supporting block is slidably arranged on the side wall of the lower shell in the up-down direction and is used to be squeezed between the two limiting blocks. The upper shell is provided with limiting grooves corresponding to the limiting buckle groups. The limiting blocks are used for abutting and arranging between the upper and lower side walls of the limiting grooves. A through groove for the two limiting blocks to pass through is opened between the lower end surface of the limiting groove and the lower end of the upper shell. An elastic pushing mechanism for pushing the supporting block towards the limiting block is arranged on the lower shell.

[0006] The utility model is further arranged as: The elastic pushing mechanism includes an elastic pushing member and an abutting plate. The abutting plate is fixedly arranged on the side wall of the lower shell and is located below the limiting block and the supporting block. The elastic pushing member is abutted and arranged between the supporting block and the abutting plate.

[0007] The present utility model is further configured as follows: The elastic pushing member includes a reed piece, the reed piece arches upward and both ends are used for detachably connecting with the abutting plate.

[0008] The present utility model is further configured as follows: Two slots are spaced apart on the abutting plate, and both ends of the reed piece are respectively snapped into the slots.

[0009] The present utility model is further configured as follows: Stopping blocks are arranged on the end parts of the limiting blocks facing away from each other, and the stopping blocks face the side wall of the lower housing and are used for abutting against the outer side wall of the upper housing.

[0010] The present utility model is further configured as follows: A guiding surrounding groove is formed on the outer side wall of the lower housing, the guiding surrounding groove extends downward from the upper end surface of the lower housing, the lower end opening of the upper housing is sleeved on the outer side of the lower housing, and the lower end surface of the upper housing abuts against the lower end surface of the guiding surrounding groove.

[0011] The present utility model is further configured as follows: A chamfer is formed on the inner side wall at the lower end of the upper housing.

[0012] In summary, the beneficial effects of the present utility model are as follows:

[0013] 1. Through this structure, when the upper housing and the lower housing are assembled, after the limiting block enters the limiting groove, the supporting block can be used to block the limiting block in the limiting groove. Compared with adjusting the placement position of the screw, controlling the position movement of the limiting block and the supporting block is simpler and clearer. Therefore, the problem of damage to the upper housing or the lower housing can be avoided.

[0014] 2. The reed piece can be pinched and taken out from the slot, and this setting enables the upper housing to be easily separated from the lower housing without the aid of other tools.

[0015] 3. The guiding surrounding groove can, on the one hand, facilitate the limiting block to enter the limiting groove from the through groove, and on the other hand, can form a support for the structure of the upper housing and strengthen the structure of the upper housing.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying Figures 1-6 drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment:

[0027] As Figures 1 to 6 shown, the present utility model discloses a contactor housing convenient for installation, including an upper shell and a lower shell. A guiding surrounding groove is formed on the outer side wall of the lower shell, and the guiding surrounding groove extends downward from the upper end surface of the lower shell. At the same time, the lower end opening of the upper shell is sleeved on the outside of the lower shell, and after the upper shell is assembled to the lower shell, the lower end surface of the upper shell abuts against the lower end surface of the guiding surrounding groove, and a chamfer is formed on the inner side wall at the lower end of the upper shell.

[0028] Limit buckle groups are arranged on the left and right side walls of the lower shell. Each limit buckle group includes two limit blocks, one in the front and the other in the rear, and a support block. The limit blocks are slidably arranged in the front and rear directions on the side wall of the lower shell provided with a guiding groove, and the support block is slidably arranged in the up and down direction on the side wall of the lower shell and is used to squeeze between the two limit blocks. At the same time, the upper shell is provided with a limit groove corresponding to the limit buckle group. In this structure, after the support block squeezes between the two limit blocks, the upper and lower end surfaces of the limit blocks are used to abut between the upper and lower side walls of the limit groove, and the end surfaces of the two limit blocks facing away from each other also exactly abut against the left and right side walls of the limit groove respectively. A through groove for the two limit blocks to pass through is formed between the lower end surface of the limit groove and the lower end of the upper shell. Moreover, an elastic pushing mechanism for pushing the support block towards the limit block is arranged on the lower shell.

[0029] The elastic pushing mechanism includes an elastic pushing member and an abutting plate. The abutting plate is fixedly arranged on the side wall of the lower shell not provided with the guiding groove and is located below the limit block and the support block, while the elastic pushing member abuts between the support block and the abutting plate. The elastic pushing member can adopt a reed piece, which arches upwards and both ends are used for detachable connection with the abutting plate. Specifically, two slots are spacedly arranged on the abutting plate, and both ends of the reed piece can be respectively clamped into the two slots in the natural state.

[0030] The working principle of the above structure is as follows: When the upper shell needs to be assembled, the support block can be first pressed downwards to make the limit blocks manually move closer to each other. At this time, the upper shell is sleeved on the lower shell. When the limit blocks enter the through groove, the support block can be released. After the limit blocks enter the limit groove, the limit blocks are toggled to move away from each other until the space between the limit blocks allows the support block to pass through. Then the support block will automatically squeeze between the two limit blocks under the action of the reed piece. At this time, the upper and lower end surfaces of the limit blocks respectively abut against the upper and lower end surfaces of the limit groove, and the assembly between the upper shell and the lower shell is completed; when the upper shell and the lower shell need to be disassembled, only the support block needs to be pressed downwards to make the limit blocks re-enter the through groove.

[0031] Blocking blocks are arranged on the ends of the limit blocks facing away from each other. The blocking blocks face the side wall of the lower shell and are used to abut against the outer side wall of the upper shell. This structure can shield and protect the groove surface of the limit groove and make the upper shell adhere to the lower shell, so that the upper shell can be assembled on the lower shell more firmly.

[0032] At the same time, it should be noted that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the protection scope of the present invention.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
