Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing, specifically to an electrical connector for plastic product manufacturing equipment. Background Technology

[0002] Injection molding equipment for plastic products is equipped with an electrical connector for connecting to an external power plug. When the injection molding equipment is not in use, the external power plug is disconnected from the electrical connector, and external debris or moisture in the air can easily damage the electrical connector. Utility Model Content

[0003] The technical problem solved by this utility model is that the electrical connector of the plastic product molding equipment is easily damaged by the external environment when it is idle.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a protective device for the electrical connector of a plastic product molding equipment, including a cover hinged to the electrical connector, a fastener that fastens the cover to the electrical connector, fastener pins on both sides of the cover, the fastener movably mounted on the electrical connector, the fastener having a fastening groove that engages with the fastening pin, arc-shaped grooves on both sides of the electrical connector, and a hinge shaft fixedly mounted on the fastener, the hinge shaft engaging in the arc-shaped groove; the cover is closed on the electrical connector, and when the fastening groove engages with the fastening pin, the center of the arc-shaped groove falls on the center line of the fastening pin.

[0005] According to the above technical solution, the cover is placed on the electrical connector. The worker rotates the locking component, which rotates around the hinge axis. Its locking groove engages with the locking pin, fixing the cover to the electrical connector. The worker then continues to rotate the locking component, which rotates around the locking pin. The hinge axis moves along the arc-shaped groove until the locking component can no longer rotate. This prevents external forces from accidentally disengaging the locking component from the locking pin.

[0006] The fastener includes a left fastener part and a right fastener part, which are connected by a connecting part. The tail of the fastener part is provided with a curved handle, which makes it easy for workers to rotate the fastener part.

[0007] The cover has a protruding edge, and the fastener has a locating pin. The cover fits onto the electrical connector, and after the locking groove engages with the locking pin, the fastener rotates about the center line of the locking pin. The locating pin engages above the protruding edge, thus preventing the fastener from rotating under external force. The end of the locating pin is chamfered or rounded. When the worker rotates the fastener, the locating pin disengages from the protruding edge, allowing the worker to rotate the fastener back to its original position.

[0008] The edge of the electrical connector is fitted with a rubber ring, and the cover contacts the rubber ring. As the latch rotates and engages with the locking pin, the cover is pressed down, causing the rubber ring to elastically deform. In this way, the rubber ring not only absorbs the downward pressure of the cover but also seals the fit between the cover and the electrical connector.

[0009] A first hinge lug is welded to the side wall of the cover, and a second hinge lug is welded to the side wall of the electrical connector. The first hinge lug and the second hinge lug are hinged together.

[0010] A spring clip is welded to the second hinge lug. When the cover rotates 90 degrees relative to the electrical connector, the end of the first hinge lug abuts against the spring clip, which then limits the first hinge lug. Thus, the cover is prevented from rotating freely and is positioned correctly.

[0011] This utility model provides a protective device for the electrical connector of a plastic product molding equipment, which can prevent the electrical connector from being damaged by the external environment. Attached Figure Description

[0023] Combination Figure 1 , Figure 2 The electrical connector protection device for plastic product molding equipment includes a cover 20 hinged to the electrical connector 10 and a fastener 30 that fastens the cover onto the electrical connector. The cover has locking pins 21 on both sides. The fastener is movably mounted on the electrical connector. The fastener has locking grooves 31 that engage with the locking pins. The electrical connector has arc-shaped grooves 11 on both sides. The fastener has a hinge shaft 32 fixedly mounted on it, which engages with the arc-shaped grooves. When the cover is closed on the electrical connector, the center of the arc-shaped groove falls on the center line of the locking pin when the locking groove engages with the locking pin.

[0024] The fastener 30 includes a left fastener portion 33 and a right fastener portion 34, which are connected by a connecting portion 35. The tail of the fastener is provided with a curved handle 36.

[0025] like Figure 4 The cover 20 has an outwardly protruding edge 22, and the fastener 30 has a positioning pin 37. The cover is closed on the electrical connector 10, and after the snap-fit ​​groove 31 and the snap-fit ​​pin 21 are engaged, the fastener rotates about the center line of the snap-fit ​​pin as the rotation axis, and the positioning pin 37 is engaged above the outwardly protruding edge.

[0026] like Figure 5 , Figure 6 The edge of the electrical connector 10 is fitted with a rubber ring 12, and the cover 20 contacts the rubber ring.

[0027] like Figure 1 A first hinge ear 23 is welded to the side wall of the cover 20, and a second hinge ear 13 is welded to the side wall of the electrical connector 10. The first hinge ear and the second hinge ear are hinged together.

[0028] like Figure 1 , Figure 5 , Figure 6 A spring piece 14 is welded onto the second hinge ear 13. When the cover 20 rotates 90 degrees relative to the electrical connection seat 10, the end of the first hinge ear 23 abuts against the spring piece, and the spring piece limits the first hinge ear.

[0029] like Figure 1 , Figure 3 The cover 20 is placed on the electrical connector 10. The worker rotates the locking member 30, which rotates around the hinge shaft 32. Its locking groove 31 engages with the locking pin 21, securing the cover 20 to the electrical connector 10. The worker then continues to rotate the locking member 30, as... Figure 4 The fastener rotates around the locking pin 21 as its rotation axis, and the hinge shaft 32 moves along the arc groove 11 until the fastener 30 can no longer rotate. At the same time, the positioning pin 37 is engaged above the protruding edge 22, thus preventing external forces from accidentally hitting the fastener 30 and causing it to disengage from the locking pin 21.

[0030] When the cover 20 is opened, the worker forcefully rotates the latching member 30, causing the positioning pin 37 to disengage from the protruding edge 22. The worker can then rotate the latching member 30, causing it to rotate back and disengage from the locking pin 21. After opening the cover 20 and rotating it upwards by 90 degrees, the end of the first hinge ear 23 abuts against the spring piece 14, which limits the first hinge ear 23. Thus, the cover 20 will not rotate freely and is thus positioned. Figure 5 , Figure 6 As shown.

[0031] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
