Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector capable of preventing glue leakage. Background Art

[0002] Connectors are essential components in various electrical equipment and electronic facilities to achieve circuit connection and signal connectivity. The main supporting fields of connectors include transportation, communications, networks, IT, medical treatment, home appliances, etc. The rapid development of product technology in supporting fields and the rapid growth of the market have strongly driven the development of connector technology. So far, connectors have developed into a series of professional products with a complete range of products, rich varieties and specifications, diverse structural types, subdivided professional directions, obvious industry characteristics, and standardized standard systems.

[0003] The Chinese utility model patent document with the authorization announcement number CN220291168U discloses a copper busbar-type through-wall high-current connector, which includes an insulating seat, a copper busbar and an end cover. The copper busbar is L-shaped, the upper end of the copper busbar is horizontally mounted on the upper end surface of the insulating seat, the lower end of the copper busbar vertically extends out of the lower end surface of the insulating seat, and the end cover covers the upper end of the insulating seat. The position where the upper end of the copper busbar contacts the upper end of the insulating seat is also sealed by glue, which can further improve the sealing performance and improve the waterproof performance.

[0004] However, for the above-mentioned copper busbar-type through-wall high-current connector, after the glue is applied to the position where the upper end of the copper busbar contacts the upper end of the insulating seat, the glue will flow out along the gap between the copper busbar and the insulating seat. After the glue flows out, uneven glue marks or stains will be formed on the surface of the connector, which not only affects the neatness of the product, but may also reduce the user's overall impression and trust in the product. Secondly, if the glue flows to the electrical contact part of the connector, it may cause poor electrical contact, short circuit or reduced insulation performance, which will seriously affect the electrical performance of the connector; in addition, after the glue overflows to the outside of the connector, it may adhere to other components, increasing the difficulty of subsequent assembly, and may even cause other components to be unable to be installed correctly or require additional cleaning steps. Utility Model Content

[0005] In order to overcome the problem in the prior art that glue will flow out along the gap between the copper busbar and the insulating seat when the connector is sealed, affecting the product appearance, electrical performance and product assembly, the utility model provides a connector that prevents glue leakage.

[0006] The technical solution of the utility model is as follows:

[0007] A connector for preventing glue leakage, comprising:

[0008] A copper busbar, wherein a glue-blocking groove is provided at the lower end of the copper busbar;

[0009] An insulating seat is provided with a receiving hole and a glue injection groove which pass through the receiving hole from top to bottom. The glue injection groove is arranged above the receiving hole and is connected with the receiving hole. The lower end of the copper busbar passes through the glue injection groove and is received in the receiving hole. The glue blocking groove portion is located in the receiving hole. Glue is injected between the glue injection groove and the outer wall of the copper busbar.

[0010] As a preferred solution of the utility model, a plurality of annular glue-blocking grooves are vertically arranged side by side at the lower end of the copper busbar to form the glue-blocking groove portion.

[0011] As a preferred solution of the utility model, the upper end of the copper busbar is a first wiring part, a first screw hole is provided on the first wiring part, the lower end of the copper busbar is a second wiring part, a second screw hole is provided on the second wiring part, and the second screw is located below the glue blocking groove part.

[0012] As a preferred solution of the utility model, a nut anti-rotation groove is provided on one side of the lower end of the insulating seat corresponding to the second screw hole, and a third screw hole is provided on the other side.

[0013] As a preferred solution of the utility model, a magnetic ring installation groove surrounding the glue injection groove is provided at the upper end of the insulating seat, and a magnetic ring is installed in the magnetic ring installation groove.

[0014] As a preferred solution of the utility model, glue is injected between the magnetic ring installation groove and the magnetic ring.

[0015] As a preferred solution of the utility model, the top height of the magnetic ring installation groove is higher than the top height of the glue injection groove, and the top height of the magnetic ring is lower than the top height of the glue injection groove.

[0016] As a preferred solution of the utility model, fixing holes are provided at the four corners of the insulating seat.

[0017] As a preferred solution of the present invention, the copper busbar is L-shaped, and the upper end of the copper busbar is level with the upper end surface of the insulating seat.

[0018] As a preferred solution of the utility model, a plurality of copper bars are provided, and a plurality of receiving holes arranged side by side and corresponding to the copper bars one by one are provided on the insulating seat.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] The utility model provides a connector for preventing glue leakage. By adding a glue-blocking groove portion at the lower end of the copper busbar, when glue is injected into the glue injection groove, part of the glue will flow downward along the gap between the copper busbar and the receiving hole. When the glue flows to the glue-blocking groove portion, the glue-blocking groove portion will change the flow direction of the glue, so that the glue flows along the glue-blocking groove portion, thereby effectively preventing the glue from flowing out of the receiving hole, solving the problems affecting the product appearance, electrical performance and product assembly. At the same time, the glue in the glue-blocking groove portion can form a buckle after solidification, thereby increasing the tightness between the copper busbar and the insulating seat and reducing the risk of loosening due to reduced viscosity or failure of the glue.

[0031] See also Figures 1 to 5The embodiment of the utility model provides a connector for preventing glue leakage, including a copper busbar 1 and an insulating seat 2. The lower end of the copper busbar 1 is provided with a glue-blocking groove portion 11. The insulating seat 2 is provided with a receiving hole 21 and a glue injection groove 22 that penetrate up and down. The glue injection groove 22 is arranged above the receiving hole 21 and communicates with the receiving hole 21. The lower end of the copper busbar 1 passes through the glue injection groove 22 and is received in the receiving hole 21, and the glue-blocking groove portion 11 is located in the receiving hole 21. Glue is injected between the glue injection groove 22 and the outer wall of the copper busbar 1 to fix the copper busbar 1, and at the same time, the sealing performance can be further improved and the waterproof performance can be improved. The utility model adds a glue-blocking groove portion 11 at the lower end of the copper busbar 1. When glue is injected into the glue injection groove 22, part of the glue will flow downward along the gap between the copper busbar 1 and the receiving hole 21. When the glue flows to the glue-blocking groove portion 11, the glue-blocking groove portion 11 will change the flow direction of the glue, so that the glue flows along the glue-blocking groove portion 11, thereby effectively preventing the glue from flowing out of the receiving hole 21, solving the problems affecting the product appearance, electrical performance and product assembly; at the same time, the glue in the glue-blocking groove portion 11 can form a buckle after solidification, thereby increasing the tightness between the copper busbar 1 and the insulating seat 2, and reducing the risk of loosening due to reduced viscosity or failure of the glue.

[0032] See also Figure 4 In one embodiment, a plurality of annular glue blocking grooves 111 are vertically arranged side by side at the lower end of the copper busbar 1 to form a glue blocking groove portion 11. The plurality of annular glue blocking grooves 111 provide multiple glue blocking mechanisms. When the glue flows from the glue injection groove 22 to the gap between the copper busbar 1 and the insulating seat 2, these glue blocking grooves 111 can change the flow direction of the glue, so that it flows along the groove instead of directly flowing out of the receiving hole 21. Each glue blocking groove 111 can capture and guide the glue, reducing the possibility of its leakage outward, thereby improving the overall reliability of the connector and reducing the failure rate caused by glue problems. At the same time, when the glue solidifies in the glue blocking groove 111, a series of snap-on structures will be formed. These snap-on structures can enhance the tightness between the copper busbar 1 and the insulating seat 2 to prevent loosening or displacement during use.

[0033] It should be noted that the present invention does not limit the number of the glue blocking grooves 111 , and those skilled in the art can set the number of the glue blocking grooves 111 as needed according to the size and length of the copper busbar 1 . The more the number of the glue blocking grooves 111 , the better the glue blocking effect.

[0034] See also Figure 4In one embodiment, the copper busbar 1 is L-shaped, and the upper end of the copper busbar 1 is horizontal with the upper end surface of the insulating seat 2. The L-shaped copper busbar 1 has strong adaptability and can meet the needs of different application scenarios. Optionally, the copper busbar 1 can be formed by sheet metal bending or obtained by profile cutting. The upper end of the copper busbar 1 is the first wiring part 12, which is mainly used for electrical connection with the input end of the power supply or other equipment. The first wiring part 12 is provided with a first screw hole 121 so as to be fixedly connected with the cable or device terminal through a screw, nut or other fastener. The lower end of the copper busbar 1 is the second wiring part 13, which is mainly used for electrical connection with the output end of the load or other equipment. The second wiring part 13 is provided with a second screw hole 131, and the second screw is located below the rubber blocking groove part 11. The second screw hole 131 is also used for fixed connection with the cable or device terminal through a screw, nut or other fastener. Among them, the second screw hole 131 is located below the rubber blocking groove part 11, ensuring that the function of the rubber blocking groove 111 will not be damaged or interfered with when the screw is tightened.

[0035] See also Figure 5 In one embodiment, a nut anti-rotation groove 23 is provided on one side of the lower end of the insulating seat 2 corresponding to the second screw hole 131, and a third screw hole 24 is provided on the other side. When the second wiring portion 13 of the copper busbar 1 is fixedly connected to the cable or device terminal through screws and nuts, the nut will be placed in the nut anti-rotation groove 23. The nut anti-rotation groove 23 can effectively prevent the nut from rotating when tightening the screw, thereby ensuring the stability and reliability of the connection, avoiding the problem of loose or unstable connection caused by rotation of the nut, and improving the safety and durability of the electrical connection. The function of the third screw hole 24 is to allow the screw to smoothly pass through the second screw hole 131 of the copper busbar 1, and then tighten with the nut placed in the nut anti-rotation groove 23, so as to firmly connect the copper busbar 1, the cable or device terminal and the insulating seat 2 together.

[0036] See also Figures 1 to 3 In one embodiment, the upper end of the insulating seat 2 is provided with a magnetic ring installation groove 25 surrounding the injection groove 22, and a magnetic ring 3 is installed in the magnetic ring installation groove 25, and the magnitude of the current on the copper bus 1 can be detected by the magnetic ring 3. The magnetic ring 3 is based on the principle of electromagnetic induction. When the current passes through the copper bus 1, a magnetic field will be generated around it. The magnetic ring 3 can sense the change of this magnetic field and convert this change into a measurable signal in a specific way (such as Hall effect or electromagnetic induction). This signal can be processed and analyzed by an appropriate circuit to obtain the current magnitude on the copper bus 1. In addition to detecting the current magnitude, the magnetic ring 3 also has a certain anti-interference ability. It can absorb or shield electromagnetic signals in the surrounding environment that may interfere with the current detection, thereby improving the accuracy and stability of the detection.

[0037] See also Figure 3In one embodiment, glue is injected between the magnetic ring installation groove 25 and the magnetic ring 3, and the magnetic ring 3 can be effectively fixed by the glue, and the stable connection between the magnetic ring 3 and the insulating seat 2 is ensured. Among them, the top height of the magnetic ring installation groove 25 is higher than the top height of the glue injection groove 22, and the top height of the magnetic ring 3 is lower than the top height of the glue injection groove 22. With the above height setting, when glue is injected into the glue injection groove 22, due to the high top height of the magnetic ring installation groove 25, the overflowing glue will naturally flow to the magnetic ring installation groove 25, and the overflowing glue will cover the gap between the magnetic ring 3 and the magnetic ring installation groove 25, thereby fixing the magnetic ring 3, and realizing that the copper bus 1 and the magnetic ring 3 can be fixed by one-time glue injection.

[0038] See also Figure 1 In one embodiment, the four corners of the insulating seat 2 are provided with fixing holes 26. The insulating seat 2 can be firmly installed at a desired position by passing screws, bolts or other fasteners through the fixing holes 26. The fixing holes 26 at the four corners make the insulating seat 2 more stable during installation, reducing the risk of loosening or displacement caused by vibration or other external forces.

[0039] In one embodiment, a plurality of copper busbars 1 are provided, and a plurality of receiving holes 21 are provided on the insulating seat 2, which are arranged side by side and correspond to the copper busbars 1 one by one. The arrangement of the receiving holes 21 arranged side by side enables a plurality of copper busbars 1 to be neatly arranged on the insulating seat 2, thereby improving the neatness and aesthetics of the electrical connection. It should be noted that the utility model does not limit the number and distribution of the copper busbars 1 and the receiving holes 21, and those skilled in the art may make adjustments according to actual needs.

[0040] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0041] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
