Description

Technical Field

[0001] This utility model relates to a connector, and more particularly to a plastic connector. Background Technology

[0002] Household appliances mainly refer to various electrical and electronic appliances used in homes and similar places. They are also known as civil appliances or daily appliances. Household appliances liberate people from heavy, tedious, and time-consuming housework, creating a more comfortable, beautiful, and healthier living and working environment for human beings, and providing a variety of cultural and entertainment conditions. They have become necessities for modern family life.

[0003] In the manufacturing of home appliances, there are many connecting parts inside. Plastic connectors are one of the commonly used parts. However, the existing plastic connectors have a small and fixed angle of tooth inclination. After the terminal is inserted for connection, when the terminal is pulled back, the tooth angle cannot be adjusted or the angle is not tilted enough, causing the tip of the barb on the terminal to abut against it. This results in a small force-bearing area for the barb, making it easy to overturn the barb. In addition, the holding force of the terminal in the plastic connector is generally weak. Utility Model Content

[0004] The purpose of this invention is to provide a plastic connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a plastic connector, comprising a plastic part, wherein a plurality of slots are provided in the middle of the plastic part, a terminal is inserted into the slot, a barb is fixedly provided on one side of the top of the terminal, a plurality of teeth are provided on one side of the top of the plastic part, a groove is provided at the bottom of the front of the teeth, a crossbar is provided in the groove, a stop plate is provided on one side of the teeth, and connecting strips are fixedly connected to both sides of the back of the stop plate.

[0006] As a preferred embodiment of this utility model, a base plate is fixedly connected to the bottom of the inner wall of the groove, and the crossbar is fixedly disposed at the top of the base plate.

[0007] As a preferred embodiment of this utility model, the two connecting strips are rotatably connected to both ends of the crossbar.

[0008] As a preferred embodiment of this utility model, the barbs are in contact with the front of the backing plate.

[0009] As a preferred embodiment of this utility model, an elastic plate is fixedly connected to the top of the front side of the tooth, and the back side of the abutment plate is in contact with the front side of the elastic plate.

[0010] As a preferred embodiment of this utility model, a label is fixedly connected to the top of the elastic plate, and the label is coated with colored ink.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by setting grooves on the teeth, in conjunction with a stop plate, crossbar and connecting strip, allows the stop plate to tilt and change multiple angles to adapt to the different angles of barbs on different terminals. When the terminal is pulled back, it can adjust to adapt to the angle of the barb, so that the barb can fit against the stop plate with a larger force-bearing area. In this way, the reaction force of the stop plate on the barb will act on the whole and the root of the barb. Compared with the traditional method of only abutting the tip of the barb, the force-bearing area is larger, making it less likely to overturn the barb of the terminal and increasing the holding force of the terminal within the plastic part.

[0013] 2. This utility model, by setting an elastic plate, can buffer the force of the barbs against the plate when pulling backward. When pulling continues, the elastic plate can contract and deform to meet the angle change of the plate. The label paper at the top of the elastic plate is coated with colored ink, so the operator can observe the color band when there is no force. When the pressure of the barbs on the plate is too great, the label paper will fold along with the contraction of the elastic plate. The operator can roughly determine the amount of force applied by the barbs to the plate by observing the area of ​​the label paper. When the applied force is too great and the label paper is almost turned into a line, it is necessary to pay attention to the adjustment to avoid continuing to pull backward and directly breaking the barbs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution for a plastic connector:

[0021] according to Figure 1 , Figure 2 and Figure 3 , Figure 4 As shown, a plastic connector includes a plastic part 1. The plastic part 1 has multiple slots 3 in the middle. Terminals 10 are inserted into the slots 3. A barb 11 is fixedly provided on one side of the top of the terminal 10. Multiple teeth 2 are provided on one side of the top of the plastic part 1. A groove 5 is provided at the bottom of the front of the teeth 2. A crossbar 7 is provided in the groove 5. A stop plate 4 is provided on one side of the teeth 2. Connecting strips 12 are fixedly connected to both sides of the back of the stop plate 4.

[0022] A base plate 6 is fixedly connected to the bottom of the inner wall of the groove 5, and a crossbar 7 is fixedly set at the top of the base plate 6. Two connecting strips 12 are rotatably connected to the two ends of the crossbar 7 respectively.

[0023] The barbs 11 are in contact with the front of the abutment plate 4. An elastic plate 8 is fixedly connected to the top of the front of the teeth 2. The elastic plate 8 is made of flame-retardant and insulating rubber and has a certain deformation capacity. The back of the abutment plate 4 is in contact with the front of the elastic plate 8.

[0024] A label paper 9 is fixedly connected to the top of the elastic plate 8. The label paper 9 is sprayed with colored ink. When the elastic plate 8 is not under force, the operator can see the complete label paper 9 from above, that is, the colored strip. When the elastic plate 8 is fully squeezed, the label paper 9 will deform accordingly, and its width is inversely proportional to the squeezing force.

[0025] In practical use, this utility model of a plastic connector involves inserting the terminal 10 into the slot 3 of the plastic component 1 to connect the terminal 10 to the plastic component 1. When the terminal 10 is pulled back, the barb 11 at its tip will first abut against the front of the abutment plate 4. The elastic plate 8 buffers the contact force. As the terminal 10 is pulled further, the barb 11 at its tip will gradually squeeze and push the abutment plate 4. If the barb 11's tilt angle does not match the abutment plate 4, it will push the abutment plate 4 to rotate slightly until the tilt angles match. In this way, the root of the barb 11 will abut against the abutment plate 4. Thus, the reaction force of the abutment plate 4 on the barb 11 will act on the entire component and its root. Compared with the traditional method of only abutting the tip of the barb 11, the force-bearing surface is larger. The larger area makes it less likely for the barbs 11 of the terminal 10 to be overturned, increasing the holding force of the terminal 10 within the plastic part 1. When the abutment plate 4 rotates, it rotates around the rotating connection between the two connecting strips 12 and the crossbar 7 to increase the original tilt angle and adapt to the angle of the barbs 11. During the pull-back process, if the abutting force is large, the elastic plate 8 will be fully squeezed and compressed, and the label paper 9 on its top will also be folded, reducing the exposed area. The operator can observe the size of the label paper 9 to roughly determine the force applied by the barbs 11 to the abutment plate 4. When the applied force is too large and the label paper 9 almost becomes a line, it is necessary to adjust it to avoid continuing to pull back and directly breaking the barbs 11.
