[0034] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0035] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] like Figures 1 to 3 As shown, an electrical connector comprises:

[0037] A base 1 is provided with a mounting hole 11, a first end 12 of the base 1 is provided with a first assembly groove 13, the first assembly groove 13 includes an outer groove wall 131 and an inner groove wall 132, and the outer groove wall 131 is higher than the inner groove wall 132;

[0038] An electrical connector 2, the electrical connector 2 is mounted on the base 1 through a mounting hole 11;

[0039] The cover body 3 includes a bottom wall 31 and a side wall 32. The bottom wall 31 is matched with the first end 12 of the base 1, and the bottom wall 31 is lower than the outer groove wall 131. The side wall 32 extends into the assembly groove;

[0040] The accommodating space formed by the outer groove wall 131 and the cover body 3 is filled with sealant (not shown in the figure).

[0041] A first assembly groove 13 is provided at the first end 12 of the base 1, into which the side wall 32 can extend. Thus, the cover 3 can cooperate with the base 1 not only through the bottom wall 31 but also through the side wall 32, thereby improving the degree of fit between the cover 3 and the base 1.

[0042] In addition, the outer groove wall 131 of the first assembly groove 13 is higher than the inner groove wall 132, and the bottom wall 31 is lower than the outer groove wall 131, so that the outer groove wall 131 and the cover body 3 form a accommodating space, and the accommodating space can be used as a space for dispensing glue, that is, glue can be dispensed into the accommodating space to fill the accommodating space with glue for sealing, and the glue is called sealant after solidification. The sealant can cover the exposed surface of the cover body 3 below the sealant, and fill the connection between the cover body 3 and the base 1, so that the base 1 and the cover body 3 are airtightly connected. Since the bottom wall 31 is lower than the outer groove wall 131, glue can be dispensed into the accommodating space to cover the bottom wall 31 of the cover body 3, so that the outer end surface of the bottom wall 31 (i.e., the exposed surface) can be covered with glue. The above-mentioned dispensing process can be completed with only one dispensing, which can simplify the dispensing process and make the dispensing operation simpler.

[0043] It should be noted that the radial width of the first assembly groove 13 can be equal to or greater than the radial width of the side wall 32. For the former, the side wall 32 can contact both the inner groove wall 132 and the outer groove wall 131; for the latter, the side wall 32 can contact the inner groove wall 132 but not the outer groove wall 131, or the side wall 32 can contact the outer groove wall 131 but not the inner groove wall 132. Regardless of the setting, as long as there is a gap between the outer side of the side wall 32 and the outer groove wall 131, the glue can flow into the gap by its own fluidity during glue dispensing, so that the gap between the outer side of the side wall 32 and the outer groove wall 131 is filled with glue.

[0044] The inner groove wall 132 of the first assembly groove 13 can be a continuous wall surface or a stepped wall surface, which is not limited in the present embodiment. If the inner groove wall 132 is a continuous wall surface, the contact between the side wall 32 and the inner groove wall 132 can be that the entire inner surface of the side wall 32 contacts the inner groove wall 132; if the inner groove wall 132 is a stepped wall surface, the contact between the side wall 32 and the inner groove wall 132 can be that part of the inner surface of the side wall 32 contacts the inner groove wall 132. Correspondingly, the same is true for the outer groove wall 131.

[0045] In addition to achieving airtightness between the base 1 and the cover 3 , the sealant also achieves connection between the cover 3 and the base 1 , so that the cover 3 and the base 1 remain relatively fixed, thereby ensuring the structural stability of the electrical connector.

[0046] For different electrical connectors, the first end 12 of the base 1 may have different meanings, and may be the front end of the base 1 or the rear end of the base 1. As an example, when the electrical connector is a socket (also called a female socket), the first end 12 of the base 1 may be the rear end of the base 1. In this example, the rear end of the base 1 of the socket is covered with sealant, and the rear end of the socket achieves airtight waterproof performance.

[0047] In the embodiment of the present application, on the one hand, by setting a first assembly groove 13 at the first end 12 of the base 1, the first assembly groove 13 includes an outer groove wall 131 and an inner groove wall 132, and the cover body 3 is set to include a bottom wall 31 and a side wall 32, the bottom wall 31 cooperates with the first end 12 of the base 1, and the side wall 32 extends into the assembly groove, which can improve the fit between the cover body 3 and the base 1; on the other hand, by making the outer groove wall 131 higher than the inner groove wall 132, and making the bottom wall 31 lower than the outer groove wall 131, an accommodating space can be formed between the outer groove wall 131 and the cover body 3, and the sealant filled in the accommodating space can completely cover the back cover of the cover body 3 and the connecting part between the base 1 and the cover body 3, which can achieve airtight waterproof performance between the base 1 and the cover body 3. It can be seen that in the embodiment of the present application, airtight waterproof performance can be achieved through the structure of the base 1 and the cover body 3 of the electrical connector itself. Compared with the prior art that requires additional sealing components, the assembly process of the electrical connector can be simplified and the risk of missing sealing components can be eliminated.

[0048] Optionally, a first flow gap 4 is provided between the side wall 32 and the outer groove wall 131;

[0049] The cover body 3 further includes an extension portion 33 extending outward from the side wall 32, the extension portion 33 is located in the assembly groove, and the extension portion 33 cooperates with the outer groove wall 131;

[0050] The first flow gap 4 is filled with sealant, and the outer end surface of the bottom wall 31 is covered with sealant.

[0051] A first flow gap 4 is provided between the side wall 32 and the outer groove wall 131 . It can be understood that the radial width of the first assembly groove 13 is greater than the radial width of the side wall 32 , and the side wall 32 does not contact the outer groove wall 131 .

[0052] In this embodiment, by setting the first flow gap 4 between the side wall 32 and the outer groove wall 131, more sealant can be filled between the outer surface of the side wall 32 and the outer groove wall 131, thereby improving the connection strength between the cover body 3 and the base 1, and enhancing the airtightness between the cover body 3 and the base 1.

[0053] In order to better understand this embodiment, two optional glue dispensing methods are provided: first, glue is dispensed to the area above the first circulation gap 4, and the glue first flows into the first circulation gap 4. After the first circulation gap 4 is filled with glue, as glue is continuously dispensed, the glue can gradually spread to cover the entire bottom wall 31. Second, glue is dispensed to the area above the bottom wall 31, and the glue gradually covers the bottom wall 31, and gradually spreads to the surroundings and flows into the first circulation gap 4 until the first circulation gap 4 is filled with glue.

[0054] Regardless of the glue dispensing method, the above glue dispensing process can be completed with only one glue dispensing, which can simplify the glue dispensing process and make the glue dispensing operation easier. In addition, the sealant covering the outer end surface of the bottom wall 31 and the sealant filling the first flow gap 4 are continuous and integrated sealants, which can maximize the structural strength of the sealant.

[0055] In addition, in this embodiment, providing the extension portion 33 on the cover body 3 has at least the following beneficial effects:

[0056] First, the extension part 33 cooperates with the outer groove wall 131, and the extension part 33 can initially support and fix the entire cover body 3, which can reduce the degree of freedom of the cover body 3 in the axial direction of the base 1, thereby improving the structural stability between the cover body 3 and the base 1.

[0057] Secondly, the extension portion 33 can serve as the bottom of the first assembly groove 13, thereby appropriately reducing the amount of glue used and appropriately reducing the cost required for the glue.

[0058] Third, since the extension portion 33 can serve as the bottom of the first assembly groove 13, the structural requirements of the first assembly groove 13 are moderately relaxed. For example, a first assembly groove 13 with a complete bottom can be provided, and a first assembly groove 13 communicating with other channels inside the base 1 can also be provided. The specific setting can be flexibly selected according to the specific needs of the electrical connector.

[0059] In this embodiment, the extension part 33 cooperates with both the outer groove wall 131 and the inner groove wall 132, which can be understood as the extension part 33 and the outer groove wall 131 are in contact and fit, or the extension part 33 and the outer groove wall 131 are interference fit. For the former, there may be a gap between the extension part 33 and the outer groove wall 131, and the glue can flow into the gap by its own fluidity during glue dispensing, so that the gap between the extension part 33 and the outer groove wall 131 is filled with glue. Since the fluidity of the glue is relatively low, after the glue fills the gap between the extension part 33 and the outer groove wall 131, it usually does not flow downward over a long distance. For the latter, the extension part 33 and the outer groove wall 131 cooperate more tightly, and there is generally no gap between the extension part 33 and the outer groove wall 131, and the glue is confined to the accommodation space above the extension part 33. It should be noted that the above here refers to the above when dispensing glue.

[0060] In order to facilitate the interference fit between the extension portion 33 and the outer groove wall 131, the outer groove wall 131 can be gradually inclined in the direction close to the inner groove wall 132, that is, the radial width of the first assembly groove 13 decreases with increasing depth. Correspondingly, the extension portion 33 can be set to a shape that is wide at the top and narrow at the bottom, that is, the outer side surface of the extension portion 33 gradually tilts inward. It should be noted that the upper and lower here refer to the relative positions during glue dispensing. In this way, when the cover body 3 is assembled to the base 1, the extension portion 33 of the cover body 3 is gradually inserted into the first assembly groove 13 along the outer groove wall 131 of the first assembly groove 13 until the extension portion 33 can no longer move downward. At this time, the extension portion 33 and the outer groove wall 131 are interference fit, and the assembly of the cover body 3 is completed.

[0061] The portion where the outer groove wall 131 of the first assembly groove 13 is located may have a certain deformation space, and the extension portion 33 may also have a certain deformation space, so that in the process of gradually inserting the extension portion 33 of the cover body 3 into the first assembly groove 13 along the outer groove wall 131 of the first assembly groove 13, at least one of the two may produce a certain deformation to achieve an interference fit between the extension portion 33 and the outer groove wall 131. In terms of the radial width of the two in a free state, the radial width of the extension portion 33 is greater than or equal to the radial width between the outer groove wall 131 and the inner groove wall 132.

[0062] Optionally, the side wall 32 is provided with at least one window 34 along the circumferential direction, a second flow gap 5 is provided between the side wall 32 and the inner groove wall 132, and the first flow gap 4 is connected with the second flow gap 5 through the at least one window 34;

[0063] The first circulation gap 4 and the second circulation gap 5 are both filled with sealant, and the outer end surface of the bottom wall 31 is covered with sealant.

[0064] In this embodiment, by setting a first flow gap 4 between the side wall 32 and the outer groove wall 131, and setting a second flow gap 5 between the side wall 32 and the inner groove wall 132, the sealant can be filled between the outer surface of the side wall 32 and the outer groove wall 131, and between the inner surface of the side wall 32 and the inner groove wall 132, which can further improve the connection strength between the cover body 3 and the base 1, and can further enhance the airtightness between the cover body 3 and the base 1.

[0065] In order to better understand the embodiment, two optional glue dispensing methods are provided: first, glue is dispensed into the upper area of ​​the first circulation gap 4, and the glue first flows into the first circulation gap 4. When enough glue is dispensed into the first circulation gap 4, the glue gradually spreads to the second circulation gap 5 through the window 34 on the side wall 32. After the first circulation gap 4 and the second circulation gap 5 are filled with glue, as glue is continuously dispensed, the glue can gradually spread to cover the entire bottom wall 31. Second, glue is dispensed into the upper area of ​​the bottom wall 31, and the glue gradually covers the bottom wall 31, and gradually spreads to the surroundings and flows into the first circulation gap 4. When enough glue flows into the first circulation gap 4, the glue gradually spreads to the second circulation gap 5 through the window 34 on the side wall 32 until the first circulation gap 4 and the second circulation gap 5 are filled with glue.

[0066] Regardless of the glue dispensing method, the above glue dispensing process can be completed with only one glue dispensing, which can simplify the glue dispensing process and make the glue dispensing operation simpler. In addition, the sealant distributed on the outer end surface of the bottom wall 31, the sealant distributed on the outer surface of the side wall 32, and the sealant distributed on the inner surface of the side wall 32 are continuous and integrated sealants, which can maximize the structural strength of the sealant.

[0067] There are many ways to form the second flow gap 5. For example, it can be achieved by setting the inner groove wall 132 to a stepped wall surface, or by setting the inner surface of the side wall 32 to a stepped surface.

[0068] Optionally, the first flow gap 4 is larger than the second flow gap 5 .

[0069] In this embodiment, the first circulation gap 4 is set to a larger circulation gap, which not only makes it easier for glue to drip or flow in, making the dispensing operation simpler, but also allows the glue to fill the first circulation gap 4 more quickly and spread to the second circulation gap 5 more quickly, shortening the time of the dispensing operation.

[0070] It should be noted that the gap involved in the embodiment of the present application can be understood as a gap that is deliberately set to keep a certain distance between components. The gap involved in the embodiment of the present application can include a structural gap existing at the connection between components.

[0071] Optionally, a second assembly groove 35 is circumferentially provided at a portion of the bottom wall 31 adjacent to the side wall 32;

[0072] The first end 12 of the base 1 is provided with a rib 14 adapted to the second assembly groove 35;

[0073] The convex rib 14 is embedded in the second assembly groove 35 .

[0074] In some electrical connectors, the mounting hole 11 on the base 1 may penetrate the entire base 1, that is, from the second end 15 of the base 1 to the first end 12 of the base 1. There may be some gaps between the bottom wall 31 and the first end 12 of the base 1. In this case, for the structure with the second flow gap 5 between the side wall 32 and the inner groove wall 132, after the glue fills the second flow gap 5, it may penetrate into the area where the mounting hole 11 of the base 1 is located along the gap between the bottom wall 31 and the first end 12 of the base 1, which may cause the glue to accidentally flow onto the surface of the electrical connector 2, thereby affecting the electrical performance of the electrical connector 2, or causing other unforeseen problems.

[0075] In view of this, this embodiment provides a circle of ribs 14 at the first end 12 of the base 1, and embeds the ribs 14 in the second assembly groove 35 of the bottom wall 31. The ribs 14 can act as a retaining wall to prevent glue from penetrating into the area where the electrical connector 2 is located, thereby preventing the glue from accidentally flowing onto the surface of the electrical connector 2 or causing other unforeseen problems.

[0076] Optionally, the at least one window 34 includes a plurality of first windows 34a and a plurality of second windows 34b, the circumferential size of the first windows 34a is different from the circumferential size of the second windows 34b, and the first windows 34a and the second windows 34b are spaced apart from each other and arranged alternately.

[0077] As an example, three first windows 34a and three second windows 34b may be provided.

[0078] In this embodiment, by providing multiple windows 34, it is not only possible to make it easier for glue to fill the second flow gap 5, speeding up the glue dispensing process, but also possible to maintain a relatively uniform structural strength of the side wall 32. By providing multiple windows 34 with different circumferential sizes, the structure of the side wall 32 can be made more flexible.

[0079] The specific size and number of the first window 34 a and the second window 34 b may be set by comprehensively considering the flow properties of the glue and the structural strength required by the side wall 32 .

[0080] Optionally, the circumferential dimensions of the side wall 32 between any adjacent first windows 34a and second windows 34b are the same.

[0081] Optionally, the circumferential size of the first window 34a is smaller than the circumferential size of the second window 34b, and the circumferential size of the side wall 32 between any adjacent first window 34a and second window 34b is comparable to the circumferential size of the first window 34a. Here, "comparable" can be understood as equal, nearly equal or not much different.

[0082] Optionally, the bottom wall 31 is further provided with a through hole 36 cooperating with the electrical connector 2 , the electrical connector 2 passes through the cover body 3 through the through hole 36 , and the end 2 a of the electrical connector 2 passing through the cover body 3 is higher than the outer groove wall 131 .

[0083] For some electrical connectors, the electrical connector 2 needs to pass through the cover body 3 to be electrically connected to other external electrical components or an external power source. In view of this, a through hole 36 that cooperates with the electrical connector 2 can be set on the bottom wall 31 so that the electrical connector 2 passes through the cover body 3 through the through hole 36.

[0084] Since the end 2a of the electrical connector 2 passing through the cover 3 needs to be electrically connected to other external electrical components or an external power source, the height of the electrical connector 2 passing through the cover 3 can be higher than the outer groove wall 131 to ensure that the end 2a of the electrical connector 2 will not be adhered to the sealant, thereby ensuring the electrical connection performance of the electrical connector 2. In addition, since the outer end surface of the bottom wall 31 is covered with sealant, the connection between the electrical connector 2 and the cover 3 can also be filled with sealant, thereby achieving an airtight connection between the electrical connector 2 and the cover 3.

[0085] In the embodiment of the present application, the cover body 3 may further include a baffle 37 protruding from the outer end surface of the bottom wall 31, and the baffle 37 roughly divides the outer end surface of the bottom wall 31 into a plurality of (including two) regions, and each region has an electrical connector 2 passing through the cover body 3. Taking the number of electrical connectors 2 as three as an example, the shape of the baffle 37 may be, for example, Y-shaped or similar to the Y-shaped.

[0086] By providing the baffle 37, on the one hand, each electrical connector 2 can maintain a certain degree of independence, thereby avoiding accidental contact between the electrical connectors 2; on the other hand, a smaller accommodating space is formed between the baffle 37 and the outer groove wall 131, which can appropriately reduce the amount of glue used and appropriately reduce the cost of glue.

[0087] Optionally, the electrical connector is a socket, the electrical connector 2 is a conductive sheet, and the second end 15 of the base 1 is further provided with a plug hole 16 communicating with the mounting hole 11 .

[0088] This embodiment takes an electrical connector such as a socket as an example. The electrical connector 2 is a conductive sheet, the number of which can be two or three. The second end 15 of the base 1 (which can be understood as the front end of the socket) can be provided with a socket 16 that communicates with the mounting hole 11.

[0089] In summary, in the embodiment of the present application, the airtight waterproof performance can be achieved through the structure of the base and cover of the electrical connector itself, which can simplify the assembly process of the electrical connector and eliminate the risk of missing seals compared to the prior art. In addition, the embodiment of the present application only needs to dispense glue once, which can simplify the dispensing process and make the dispensing operation simpler.

[0090] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the protection scope of this application.
