Description

Technical Field

[0001] The utility model relates to the field of contactors, in particular to a protective shell for a contactor of an injection molding machine. Background Art

[0002] The existing contactor reference Figure 1 , including a contactor body 1, a plurality of screw mounting holes 2 symmetrically and spaced at the upper end of the contactor body 1, and short-circuiting pieces 3 symmetrically arranged at both ends of the contactor body 1. Two threaded holes 4 for connecting wires are arranged on each of the two short-circuiting pieces 3.

[0003] The short-circuiting pieces can be divided into short-circuiting pieces with insulation and short-circuiting pieces without insulation. If the short-circuiting pieces installed on the contactor body are short-circuiting pieces without insulation, when an operator connects the short-circuiting pieces on the contactor body, if the wire accidentally abuts against the short-circuiting pieces on other contactor bodies, it may cause a short circuit of the accidentally contacted contactor body. If the operator's body accidentally contacts other short-circuiting pieces, it may also cause the operator to be accidentally electrocuted. Content of the Utility Model

[0004] Aiming at the disadvantage that when the short-circuiting pieces of the existing contactor are short-circuiting pieces without insulation, the misoperation of the operator will cause the contactor to short-circuit or even cause electric shock to the personnel, the utility model provides a protective shell for a contactor of an injection molding machine.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A protective shell for a contactor of an injection molding machine, including a shell for covering outside the contactor body, and a fixing component arranged on the shell for fixing the shell outside the contactor body when the shell is covered outside the contactor body.

[0007] By adopting the above scheme, the shell can be installed on the contactor body through the arranged fixing component, so as to reduce the probability that when an operator connects a wire to the short-circuiting piece on the contactor body, the wire contacts the short-circuiting piece on other contactors, and at the same time, it can also reduce the probability that when an operator connects a wire to the short-circuiting piece on the contactor body, the human body contacts the short-circuiting piece on other contactor bodies.

[0008] Preferably, the fixing component includes a positioning component for driving the shell to quickly cover the contactor body and a limiting component for limiting when the shell is covered with the contactor body.

[0009] Preferably, the positioning component includes at least two positioning posts protruding from the inner wall of the shell for guiding the installation of the shell after being inserted into the screw mounting holes on the contactor body.

[0010] With the above solution, when the housing is covered onto the contactor body, the positioning posts provided can be inserted into the screw mounting holes on the contactor body, so that the housing can be quickly covered onto the contactor body, and it is also convenient for the subsequent installation of the limiting components.

[0011] Preferably, the limiting component includes a fixing hole provided on the housing that is aligned with the threaded hole when the housing is covered on the contactor body, and a screw that can partially pass through the fixing hole and then be screwed into the threaded hole.

[0012] With the above solution, when the housing is installed onto the contactor body through the positioning component, the screw can pass through the fixing hole on the housing and be screwed into the threaded hole on the shorting piece, thereby reducing the probability that the housing installed on the contactor body detaches from the contactor body.

[0013] Preferably, a supporting component is provided between the fixing hole and the threaded hole to reduce the probability of the housing being deformed under pressure when the screw is screwed into the threaded hole.

[0014] Preferably, the supporting component includes a threaded sleeve. The screw passes through the fixing hole and the threaded sleeve and is tightly fitted with the threaded hole. The two ends of the threaded sleeve are respectively in abutting cooperation with the shorting piece and the housing.

[0015] With the above solution, when the housing is installed onto the contactor body, the two ends of the threaded sleeve can respectively abut against the inner wall of the housing and the surface of the shorting piece. At this time, the threaded sleeve will support the housing, thereby reducing the probability of deformation on the surface of the housing when the screw is screwed from the fixing hole into the threaded hole.

[0016] Preferably, a plurality of wire outlet grooves for increasing the neatness of wire routing are recessed on the side wall of the housing.

[0017] With the above solution, the wires connected to the contactor body can pass through the wire outlet grooves, so that the wire routing of the contactor body is more neat.

[0018] Since the present utility model adopts the above technical solutions, it has remarkable technical effects: the housing can be installed onto the contactor body through the provided fixing components, thereby reducing the probability that the wires contact the shorting pieces on other contactors when the operator connects the wires to the shorting pieces on the contactor body, and at the same time, it can also reduce the probability that the operator's body contacts the shorting pieces on other contactor bodies when connecting the wires to the shorting pieces on the contactor body.

[0024] Embodiment

[0025] An injection molding machine contactor protective housing, referring to Figures 2 - 3 , includes a housing 5 for covering outside the contactor body 1, and a fixing component is provided on the housing 5 to fix the housing 5 outside the contactor body 1 when the housing 5 is covered outside the contactor body 1. A plurality of outgoing wire grooves 10 for increasing the neatness of wire routing are recessed on the side wall of the housing 5. The fixing component includes a positioning component for driving the housing 5 to quickly cover the contactor body 1 and a limiting component for limiting after the housing 5 is covered with the contactor body 1. The positioning component includes at least two positioning posts 6 protruding from the inner wall of the housing 5 to guide the installation of the housing 5 after being inserted into the screw mounting holes 2 on the contactor body 1. In this embodiment, 4 positioning posts 6 are provided. The limiting component includes a fixing hole 8 provided on the housing 5 that is aligned with the threaded hole 4 when the housing 5 is covered on the contactor body 1 and a screw 7 that can partially pass through the fixing hole 8 and then be screwed into the threaded hole 4.

[0026] A support component for reducing the probability of the housing 5 being deformed under pressure when the screw 7 is screwed into the threaded hole 4 is provided between the fixing hole 8 and the threaded hole 4. The support component includes a threaded sleeve 9. The screw 7 passes through the fixing hole 8 and the threaded sleeve 9 and is tightly fitted with the threaded hole 4. Both ends of the threaded sleeve 9 are in abutting cooperation with the shorting piece 3 and the housing 5 respectively.

[0027] Specific installation process: When the housing 5 needs to be installed on the contactor body 1, first, insert the screw 7 through the fixing hole 8 on the housing 5. Then, partially screw the threaded sleeve 9 onto the screw 7. Next, move the housing 5 above the contactor body 1. After that, position and install the housing 5 on the contactor body 1 by inserting the positioning post 6 in the housing 5 into the screw positioning hole 2 on the contactor body 1. At this time, the threaded sleeve 9 partially screwed into the screw 7 will be aligned with the threaded hole 4 on the short-circuiting piece 3. Then, rotate the screw 7 so that the screw 7 passes through the threaded sleeve 9 and screws into the threaded hole 4. At this time, the installation between the housing 5 and the contactor body 1 can be completed, thereby reducing the probability that the wire contacts the short-circuiting piece 3 on other contactors when the operator connects the wire to the short-circuiting piece 3 on the contactor body 1. At the same time, it can also reduce the probability that the human body contacts the short-circuiting piece 3 on other contactor bodies 1 when the operator connects the wire to the short-circuiting piece 3 on the contactor body 1.
