Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to an auxiliary plugging tool for rectangular connectors. Background Art

[0002] The rectangular connector is a common electrical connector, mainly used for current transmission. The existing rectangular connector plug-in methods are mainly manual push-in plug-in and end-side bolt tightening plug-in:

[0003] Manual push-in and plug-in are suitable for situations where there are a small number of cores, low insertion and removal force, and easy access. Due to the variety of rectangular connectors and the different number of cores, some rectangular connectors cannot be manually pushed in and plugged in. At the same time, when the connector is installed in a small space inside the box, it is difficult to reach with hands and make a plug-in connection.

[0004] The method of tightening and plugging the end bolts can apply greater force, which is suitable for situations where there are a large number of core parts and the insertion and removal force is large. At the same time, a long-handled screwdriver can be used for tightening and plugging when working in a small space.

[0005] However, due to the characteristics of the insulating board and product performance requirements, the tightening screws are set on the end side of the insulating board. When tightening, when there are too many core parts, the middle core part supports it, and when force is applied on both sides, the insulating board and the spring piece will be deformed, which will cause the insulating board to crack, affecting the product quality. It cannot guarantee the plug-in connection when the number of connector core parts is large and the plug-in force is too large.

[0006] Therefore, we designed a rectangular connector auxiliary plug-in tooling. Utility Model Content

[0007] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a rectangular connector auxiliary plugging tool.

[0008] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0009] A rectangular connector auxiliary plug-in tooling comprises a connecting plate, the bottom side wall of the connecting plate is fixedly connected to a fixed clamping plate, the upper surface of the fixed clamping plate is fixedly connected to a guide rod, the outer wall of the guide rod is slidably sleeved with a movable clamping plate, the outer wall of the guide rod is sleeved with a reset spring, the reset spring is located between the movable clamping plate and the fixed clamping plate, the top side wall of the connecting plate is rotatably connected to an eccentric block, the eccentric block is located directly above the movable clamping plate, the eccentric block and the movable clamping plate are in contact with each other, and the outer wall of the eccentric block is fixedly connected to a handle.

[0010] Preferably, the fixed clamping plate and the connecting plate are fixedly connected by screws, a threaded hole is provided on the upper surface of the fixed clamping plate, an external thread is provided on the bottom of the guide rod, and the fixed clamping plate is threadedly connected to the guide rod.

[0011] Preferably, a through hole is formed in the top of the connecting plate. A bushing is sleeved in the through hole at the top of the connecting plate. A rotating shaft is fixedly connected to the outer wall of the eccentric block. The rotating shaft and the bushing are sleeved with each other. A retaining ring is sleeved at one end of the rotating shaft away from the eccentric block.

[0012] Preferably, a flat washer is sleeved on the outer wall of the rotating shaft. The flat washer is located between the retaining ring and the connecting plate.

[0013] Preferably, a limiting hole is formed in the outer wall of the connecting plate. A positioning pin is inserted into the limiting hole. One end of the positioning pin is fixedly connected to the outer wall of the moving clamping plate.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. In the utility model, two rectangular connectors to be inserted are placed between the fixed clamping plate and the moving clamping plate. The handle is manually pressed. The handle drives the eccentric block to deflect. The eccentric block presses the moving clamping plate to move downward, realizing the auxiliary insertion of the two rectangular connectors. The device can quickly insert connectors with a large number of core components and large insertion and extraction forces, improving the efficiency; and during the insertion operation, the force is evenly distributed, preventing damage to the insulating plate, improving the product quality, and the tooling is simple to operate, without transmission components such as motors and chains, with low maintenance costs, and also solves the problem that manual insertion is impossible in a complex environment.

[0016] 2. In the utility model, a return spring is sleeved on the outer wall of the guide rod. The return spring is installed between the fixed clamping plate and the moving clamping plate. After the force is removed, the moving clamping plate can be automatically reset, realizing continuous operation.

[0017] 3. In the utility model, when the moving clamping plate moves downward, a limiting hole and a positioning pin are arranged on one side of the moving clamping plate. The limiting hole and the positioning pin can prevent the moving clamping plate and the guide rod from generating left and right offsets after long-term operation, affecting the pressing accuracy.
