Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a waterproof electrical connector. Background Technology

[0002] Existing connectors, such as the patented product previously introduced by our company, with prior art publication number CN210607825U, typically use sealing rings to seal between the terminals and the housing, as well as between the housing and the wires. While this provides some waterproofing capability, the waterproofing effect is limited, and its waterproofing capability is still insufficient when used in water-related applications. Utility Model Content

[0003] The purpose of this invention is to provide a waterproof electrical connector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a waterproof electrical connector, comprising a housing and a terminal block installed at one end of the housing; the terminal block includes a support portion, one side of which is inserted into the housing via a plug portion, and the other side of the support portion is provided with a plug; the plug is provided with a first partition cavity and a second partition cavity, a first terminal is installed in the first partition cavity, and a second terminal is installed in the second partition cavity; after one end of the terminal block is inserted into the housing, the wire on the terminal block passes through the housing and exits from the other side of the housing, and then sealant is injected into the housing to seal the terminal block and the wire.

[0005] As a preferred technical solution of this utility model: the connection between the housing and the terminal block is provided with a groove, and the inner wall surface of the housing is also provided with a protrusion.

[0006] As a preferred technical solution of this utility model: the plug part is further provided with annular grooves, and there are multiple annular grooves distributed along the length direction of the plug part.

[0007] As a preferred technical solution of this utility model: the first partition cavity is flat, and the number of the first terminals is multiple and arranged side by side in the first partition cavity.

[0008] As a preferred technical solution of this utility model: the number of the second partition cavities is two, and the two second terminals are separated by the two second partition cavities.

[0009] As a preferred technical solution of this utility model: the side of the plug-in portion facing the housing is further provided with a first partition and a second partition, and the first partition separates the first terminal from the second terminal, and the second partition separates the two second terminals.

[0010] As a preferred technical solution of this utility model: the first partition is placed horizontally on the plug-in part, the second partition is vertically arranged on the plug-in part, and one end of the second partition is connected to the first partition.

[0011] As a preferred technical solution of this utility model: the ends of the first terminal and the second terminal facing the wire are tubular structures, and both the ends of the first terminal and the second terminal facing the wire are provided with slots.

[0012] The beneficial effects of this utility model using the above technical solution are as follows: After the terminal block is inserted into the housing, the wire installed on the terminal block exits from the other side of the housing. Then, sealant is poured into the housing. Therefore, after the sealant solidifies, the housing and the terminal block become an integral structure, thus improving the sealing performance of the electrical connector compared to the prior art, allowing it to be used in water-related environments. Simultaneously, the integral structure of the terminal block and housing after the sealant solidifies enhances the overall structural strength of the electrical connector, reducing deformation and damage to the equipment during insertion and removal, thereby extending the service life of the equipment.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0020] Please see Figure 1-5 This utility model provides an embodiment of a waterproof electrical connector, comprising a housing 1 and a terminal block 2 installed at one end of the housing 1; the terminal block 2 includes a support portion 9, one side of which is inserted into the housing 1 through a plug portion 7, and the other side of the support portion 9 is provided with a plug 8; the plug 8 is provided with a first partition cavity 10 and a second partition cavity 11, a first terminal 3 is installed in the first partition cavity 10, and a second terminal 5 is installed in the second partition cavity 11; after one end of the terminal block 2 is inserted into the housing 1, the wire on the terminal block 2 passes through the housing 1 and exits from the other side of the housing 1, and then sealant is injected into the housing 1 to seal the terminal block 2 and the wire.

[0021] In summary, after terminal 2 is inserted into housing 1, the wires mounted on terminal 2 exit from the other side of housing 1. Then, sealant is poured into housing 1. Once the sealant solidifies, housing 1 and terminal 2 become a single unit, thus improving the sealing performance of the connector compared to existing technologies, allowing for use in water-related environments. Furthermore, the solidification of the sealant, with terminal 2 and housing 1 forming a single unit, enhances the overall structural strength of the connector, reducing deformation and damage during insertion and removal, and extending the device's lifespan.

[0022] Furthermore, a groove 15 is provided at the connection between the housing 1 and the terminal 2, and a protrusion 14 is also provided on the inner wall surface of the housing 1. Therefore, the groove 15 and the protrusion 14 can be used to make the inner wall surface of the housing 1 uneven, increasing the contact area between the sealant and the housing 1, so as to improve the stability and sealing performance of the sealant after curing.

[0023] Furthermore, since the plug-in portion 7 is also provided with annular grooves 12, and there are multiple annular grooves 12 distributed along the length of the plug-in portion 7, the sealing adhesive has more contact surfaces, thereby further improving the stability of the connection between the terminal 2 and the housing 1.

[0024] To avoid interference between the terminals during operation, the first partition cavity 10 is flat, and multiple first terminals 3 are arranged side-by-side within it. Similarly, there are two second partition cavities 11, which separate the two second terminals 5. This isolates the first terminals 3 and the second terminals 5 within the plug 8, reducing interference.

[0025] In addition, the side of the connector 7 facing the housing 1 is provided with a first partition 4 and a second partition 6. The first partition 4 separates the first terminal 3 from the second terminal 5, and the second partition 6 separates the two second terminals 5. This isolates the first terminal 3 and the second terminal 5 from each other on one side of the connector 7, reducing interference.

[0026] Furthermore, since the first partition 4 is horizontally placed on the plug-in portion 7 and the second partition 6 is vertically arranged on the plug-in portion 7, and one end of the second partition 6 is connected to the first partition 4, the two partitions are connected together while performing the isolation function. This not only improves the structural strength of the end face of the plug-in portion 7, but also expands the contact area between the sealant and the terminal 2, thereby further improving the sealing performance of the device.

[0027] Based on the above solution, since the ends of the first terminal 3 and the second terminal 5 facing the wire are tubular structures, and both the ends of the first terminal 3 and the second terminal 5 facing the wire are provided with slots 13, the slots 13 can guide the molten solder into the inside of the terminal and expand the contact area between the molten solder and the terminal, thus enabling the wire to be reliably soldered onto the terminal.

[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
