[0189] like Figures 3 to 7 and Fig.12 As shown, the housing 10 includes a plurality of walls enclosing the accommodating cavity 11. Specifically, the housing body 100 of the housing 10 includes a first end 101 and a second end 102 opposite to each other in the transverse direction XX, a first side wall 103 at the second end 102, and a second side wall 104, a third side wall 105 and a bottom wall 106 extending between the first end 101 and the second end 102. The second side wall 104 and the third side wall 105 are opposite to each other in the longitudinal direction YY. The bottom wall 106 extends along the longitudinal direction YY between the second side wall 104 and the third side wall 105. The first side wall 103 connects the second side wall 104, the third side wall 105 and the bottom wall 106. The first side wall 103, the second side wall 104, the third side wall 105 and the bottom wall 106 of the housing body 100 can form four walls among the plurality of walls of the housing 10. In addition, as will be described in detail below, the first cover 200 can form one of the multiple walls of the housing 10, and the second cover 300 can form another of the multiple walls of the housing 10. The first side wall 103, the second side wall 104, the third side wall 105 and the bottom wall 106 of the housing body 100, the first cover 200 and the second cover 300 enclose the accommodating cavity 11.

[0190] In some embodiments, the housing body 100 may include an outwardly protruding mounting portion 12 and a screw hole 13 formed in the mounting portion 12. With this configuration, the electrical connector 1 can be reliably fixed, for example, to a panel, using fasteners such as screws and pins.

[0191] The housing body 100, the first cover body 200 and the second cover body 300 may be made of any suitable material. For example, the housing body 100, the first cover body 200 and the second cover body 300 may be made of an insulating material. Examples of insulating materials suitable for manufacturing the housing body 100, the first cover body 200 and the second cover body 300 include, but are not limited to, plastic, nylon, liquid crystal polymer (LCP), polyphenylene sulfide (PPS), high temperature nylon or polyphenylene oxide (PPO) or polypropylene (PP).

[0192] Please continue to see Figures 3 to 7 and Fig.12 The housing cavity 11 is located in the housing body 100. The housing body 100 includes a first opening 107 ( Figure 5 ) to allow the cable 30 to extend into the accommodating cavity 11 through the first opening 107.

[0193] The first cover 200 is mounted on the first end 101 of the housing body 100 to close the first opening 107. As described above, one of the walls of the housing 10 is formed by the first cover 200. Fig.14 2 is a three-dimensional diagram of the first cover body 200. Fig.14 As shown, the first cover body 200 (or referred to as the "first wall" of the shell 10) includes a dispensing cavity 200a formed in the first cover body 200, a first channel 210 extending from the dispensing cavity 200a through a first portion 201 of the first cover body 200 to the outside of the shell 10, and a second channel 220 extending from the dispensing cavity 200a through a second portion 202 of the first cover body 200 to the accommodating cavity 11.

[0194] like Figures 1 to 5 , Figure 7 and Figure 11 to Figure 12 As shown, the cable 30 includes a power line 31 configured to transmit power and a signal line 32 configured to transmit a signal. The sections of the power line 31 and the signal line 32 extending outside the housing 10 may be surrounded by the same sleeve 50. It should be understood that the present application is not limited thereto, and the sections of the power line 31 and the signal line 32 extending outside the housing 10 may each be surrounded by a separate sleeve, or there may be no sleeve.

[0195] The power cord 31 (also referred to as a "first cable") includes a conductor 33 and a sheath 34 surrounding the conductor 33. The power cord 31 is shown as having four conductors 33, but the present application is not limited thereto. The section of the sheath 34 at the end 31a of the power cord 31 is removed so that the conductor 33 extends beyond the end 34a of the sheath 34. The conductor 33 may include a conductor 33a and an insulator 33b surrounding the conductor. The section of the insulator 33b corresponding to the connection portion of the conductor 33a and the power connection module 21 is removed. This enables the power cord 31 to be ready to be connected to the power connection module 21.

[0196] Similar to the power cord 31, the signal line 32 (also referred to as a "second cable") includes a conductor 35 and a sheath 36 surrounding the conductor 35. The signal line 32 is shown as having two conductors 35, but the present application is not limited thereto. The section of the sheath 36 at the end 32a of the signal line 32 is removed so that the conductor 35 extends beyond the end 36a of the sheath 36. The conductor 35 may include a conductor 35a and an insulator 35b surrounding the conductor. The section of the insulator 35b corresponding to the connection portion of the conductor 35a with the signal connection module 22 is removed. This enables the signal line 32 to be ready to be connected to the signal connection module 22. In some embodiments, the signal line 32 may include a shielding sleeve (not shown) disposed at the end 36a of the sheath 36.

[0197] The first cover 200 Fig.14 The first cover 200 is shown as including two first holes 210, which correspond to the power line 31 and the signal line 32 of the cable 30, respectively, so as to allow the power line 31 and the signal line 32 to extend from the outside of the housing 10 through the corresponding first holes 210 into the dispensing cavity 200a. Fig.14 2 and 3. The embodiment of the present invention is shown to include two second holes 220 to correspond to the power line 31 and the signal line 32 of the cable 30, respectively, so as to allow the power line 31 and the signal line 32 to extend from the dispensing cavity 200a to the accommodating cavity 11 via the corresponding second holes 220. It should be understood that the present application is not limited thereto, and the number of the first hole 210 and the second hole 220 can be one or more than two.

[0198] like Figures 2 to 9 As shown, the electrical connection module 20 includes a power connection module 21 configured to transmit power and a signal connection module 22 configured to transmit signals.

[0199] The power connection module 21 may include a main body 21a and a power terminal (not shown) held by the main body 21a. The power terminal may be formed of a conductive material. The power terminal may include a mating end (not shown), a mounting end 21b opposite to the mating end, and an intermediate portion extending between the mating end and the mounting end. The mating end of the power terminal is configured to be connected to a conductor 33a of a corresponding wire 33 of a power cord 31. The mounting end 21b of the power terminal may be configured to be mounted to a circuit board (not shown) such as a main board of a vehicle lidar. Figure 2 and Figures 4 to 7 As shown, when the power connection module 21 is installed in the housing 10, the main body 21a is located in the accommodating cavity 11, and the mounting end 21b extends through the bottom wall 106 of the housing body 100 to the outside of the housing body 100 for mounting on the circuit board. It should be understood that the present application is not limited thereto, and in some embodiments, the power connection module 21 may be located as a whole in the accommodating cavity 11. That is, the power connection module 21 may be at least partially disposed in the accommodating cavity 11. It should also be understood that the specific form of the power connection module 21 is not limited thereto.

[0200] The signal connection module 22 may include a main body 22a and a signal terminal (not shown) held by the main body 22a. The signal terminal may be formed of a conductive material. The signal terminal may include a mating end (not shown), a mounting end 22b opposite the mating end, and an intermediate portion extending between the mating end and the mounting end. The mating end of the signal terminal is configured to be connected to a conductor 35a of a corresponding wire 35 of the signal line 32. The mounting end 22b of the signal terminal may be configured to be mounted to a circuit board (not shown) such as a main board of a vehicle lidar. Figure 2 and Figures 4 to 7 As shown, when the signal connection module 22 is installed in the housing 10, the main body 22a is located in the accommodating cavity 11, and the mounting end 22b extends through the bottom wall 106 of the housing body 100 to the outside of the housing body 100 for mounting on the circuit board. It should be understood that the present application is not limited thereto, and in some embodiments, the signal connection module 22 may be located as a whole in the accommodating cavity 11. That is, the signal connection module 22 may be at least partially disposed in the accommodating cavity 11. It should also be understood that the specific form of the signal connection module 22 is not limited thereto.

[0201] like Figure 4As shown, the cable 30 extends from the outside of the housing 10 through the first hole 210, the dispensing cavity 200a and the second hole 220 of the first cover 200 to the accommodating cavity 11, and is connected to the electrical connection module 20 at the end of the cable 30. Specifically, the power line 31 extends from the outside of the housing 10 through the corresponding first hole 210, the dispensing cavity 200a and the corresponding second hole 220 of the first cover 200 to the accommodating cavity 11, and is connected to the power connection module 21 at the end 31a of the power line 31. The signal line 32 extends from the outside of the housing 10 through the corresponding first hole 210, the dispensing cavity 200a and the corresponding second hole 220 of the first cover 200 to the accommodating cavity 11, and is connected to the signal connection module 22 at the end 32a of the signal line 32.

[0202] In some embodiments, the cable 30 may extend through the first hole 210, the glue dispensing cavity 200a, and the second hole 220 of the first cover 200 before the first cover 200 is installed on the first end 101 of the housing body 100. Alternatively, the cable 30 may extend through the first hole 210, the glue dispensing cavity 200a, and the second hole 220 of the first cover 200 after the first cover 200 is installed on the first end 101 of the housing body 100.

[0203] In some embodiments, the cable 30 may be connected to the electrical connection module 20 before the electrical connection module 20 is mounted on the housing body 100. Alternatively, the cable 30 may be connected to the electrical connection module 20 after the electrical connection module 20 is mounted on the housing body 100.

[0204] In some embodiments, the electrical connector 1 may include a first adhesive 41. Figure 1 , Figure 7 and Fig.12As best shown, the first adhesive 41 is filled in the dispensing cavity 200a of the first cover 200 and is disposed around the section of the cable 30 (i.e., the power line 31 and the signal line 32) located in the dispensing cavity 200a to fix the cable 30 relative to the first cover 200. The first adhesive 41 can be applied after the first cover 200 is mounted on the first end 101 of the housing body 100 and the cable 30 extends through the first channel 210, the dispensing cavity 200a, and the second channel 220 of the first cover 200. Using the first adhesive 41 to fix the cable 30 relative to the first cover 200 can improve the tensile strength of the cable 30, improve the vibration resistance of the electrical connector 1, and thus improve the reliability of the electrical connector 1. In addition, compared with using an SR (strain relief) outer mold to fix the cable 30, using the first adhesive 41 to fix the cable 30 relative to the first cover 200 can reduce the volume of the electrical connector 1 and reduce the complexity and manufacturing cost of the manufacturing process of the electrical connector 1. The first adhesive 41 can also be called a "fixing member" or "fixing glue".

[0205] The first adhesive 41 may be UV adhesive, silicone, epoxy adhesive or any other suitable type of adhesive. For example, the first adhesive 41 may be an underfill, such as a silicone underfill (such as polysiloxane, polydimethylsiloxane), an epoxy underfill (such as epoxy resin, epoxy acrylate), a polyurethane underfill (such as polyurethane resin, polyurethane acrylate) or an acrylate underfill (such as acrylate monomer, acrylate copolymer).

[0206] In some embodiments, the first cover 200 can be mounted on the housing body 100 by any suitable means such as snap fit, latch mechanism, hot melt welding, etc. For example, the housing body 100 can be provided with a snap fit structure (not shown) at the first end 101, and the first cover 200 can be provided with a matching snap fit structure (not shown). The snap fit structure of the housing body 100 and the matching snap fit structure of the first cover 200 can cooperate with each other to reliably mount the first cover 200 on the first end 101 of the housing body 100.

[0207] like Figures 4 to 6 As best shown, when the first cover 200 is mounted on the first end 101 of the housing body 100 , the second portion 202 of the first cover 200 is adjacent to the accommodating cavity 11 , and the first surface 202 a of the second portion 202 of the first cover 200 faces the accommodating cavity 11 .

[0208] In some embodiments, the second portion 202 of the first cover 200 includes a slot (not shown) extending from the first surface 202a through the second portion 202 to the dispensing cavity 200a. Figure 5 ) can be inserted into the slot. The first adhesive 41 can be engaged with the portion 101a of the first end 101 of the shell body 100. As an example, the first adhesive 41 can extend into the slot of the second portion 202 to engage with the portion 101a of the first end 101 of the shell body 100. As another example, a first surface 101b of a portion 101a of the first end 101 of the shell body 100 can be exposed in the dispensing cavity 200a of the first cover body 200, and the first adhesive 41 can be set on the first surface 101b. The first adhesive 41 is engaged with the aforementioned portion 101a of the first end 101 of the shell body 100, which can improve the connection strength between the first cover body 200 and the shell body 100, so as to improve the vibration resistance of the electrical connector 1. It should be understood that in some other embodiments, the first cover 200 may be retained to the first end 101 of the housing body 100 only by the first adhesive 41 being engaged with the aforementioned portion 101 a of the first end 101 of the housing body 100 .

[0209] Alternatively, in an embodiment where the first surface 101b of the aforementioned portion 101a of the first end 101 of the housing body 100 is exposed in the dispensing cavity 200a of the first cover 200, the aforementioned portion 101a of the first end 101 of the housing body 100 may include a protrusion 101c protruding from the first surface 101b into the dispensing cavity 200a. The first adhesive 41 may be disposed on the first surface 101b and engaged with the protrusion 101c. In this way, the connection strength between the first cover 200 and the housing body 100 can be further improved. In addition, the deformation of the first adhesive 41 when the cable 30 is pulled can be suppressed, thereby further improving the tensile strength of the cable 30. As an example, as shown in the figure, the protrusion 101c can be configured as a barb.

[0210] Alternatively or additionally, in an embodiment where the first surface 101b of the aforementioned portion 101a of the first end 101 of the housing body 100 is exposed in the dispensing cavity 200a of the first cover 200, the aforementioned portion 101a of the first end 101 of the housing body 100 may include a recessed portion 101d recessed from the first surface 101b into the aforementioned portion 101a. The first adhesive 41 may be disposed on the first surface 101b and filled in the recessed portion 101d. In this way, the connection strength between the first cover 200 and the housing body 100 can be further improved. In addition, the deformation of the first adhesive 41 when the cable 30 is pulled can be suppressed, thereby further improving the tensile strength of the cable 30.

[0211] In some embodiments, Figure 4As best shown, the section of the cable 30 located in the glue dispensing cavity 200a can extend along the transverse direction XX. The first cover 200 may include a second opening 200b, which extends from the outside of the housing 10 along a longitudinal direction YY perpendicular to the transverse direction XX through the third portion 203 of the first cover 200 to the glue dispensing cavity 200a to allow the first adhesive 41 to be filled into the glue dispensing cavity 200a via the second opening 200b. Through this configuration, it is convenient to fill the first adhesive 41 in the glue dispensing cavity 200a and arrange it around the section of the cable 30 located in the glue dispensing cavity 200a. In addition, the second opening 200b can be used as an inspection window to facilitate checking the filling of the first adhesive 41 in the glue dispensing cavity 200a.

[0212] In one of these embodiments, the first part 201 and the second part 202 of the first cover 200 can be opposite to each other in the transverse direction XX and spaced apart from each other by the glue dispensing cavity 200a, and the third part 203 connects the first part 201 and the second part 202. The first channel 210 and the second channel 220 can extend along the transverse direction XX, respectively. The cross section of the glue dispensing cavity 200a perpendicular to the transverse direction XX can be greater than the cross section of the first channel 210 perpendicular to the transverse direction XX, and can be greater than the cross section of the second channel 220 perpendicular to the transverse direction XX. Through this configuration, the first adhesive 41 can be reliably engaged with the inner wall of the glue dispensing cavity 200a, thereby improving the tensile strength of the cable 30. In some examples, the first channel 210 and the second channel 220 are aligned with each other in the transverse direction XX. It should be understood that the present application is not limited thereto, and the first channel 210 and the second channel 220 can be partially or completely staggered from each other in the transverse direction XX.

[0213] Alternatively or additionally, in an embodiment where the first surface 101b of the aforementioned portion 101a of the first end 101 of the housing body 100 is exposed in the dispensing cavity 200a of the first cover 200, the first surface 101b of the aforementioned portion 101a of the first end 101 of the housing body 100 may be exposed in the dispensing cavity 200a on a side of the section of the cable 30 that is away from the second opening 200b. The first adhesive 41 may be disposed on the first surface 101b and bonded to the first surface 101b. Figure 5 and Figure 6As best shown, the first cover 200 may also include a fourth portion 204, which is opposite to the third portion 203 in the longitudinal direction YY and is spaced apart from each other by the dispensing cavity 200a. The fourth portion 204 may include a second face 204a facing the dispensing cavity 200a and a groove 204b that is recessed from the second face 204a into the fourth portion 204 and communicates with the slot in the second portion 202. The aforementioned portion 101a of the first end 101 of the housing body 100 is inserted into the groove 204b through the slot of the second portion 202 of the first cover 200, and the first surface 101b of the aforementioned portion 101a is flush with the second face 204a of the fourth portion 204. In some embodiments, as described above, the aforementioned portion 101a of the first end 101 of the housing body 100 may include a protrusion 101c that protrudes from the first surface 101b into the dispensing cavity 200a. The first adhesive 41 can be set on the first surface 101b and engage with the protrusion 101c. For example, the protrusion 101c can be configured as a barb. Alternatively or additionally, in some embodiments, as described above, the aforementioned part 101a of the first end 101 of the shell body 100 may include a recessed portion 101d recessed from the first surface 101b into the aforementioned part 101a. The first adhesive 41 can be set on the first surface 101b and filled in the recessed portion 101d. By at least one of these configurations, the connection strength between the first cover 200 and the shell body 100 can be further improved. In addition, the deformation of the first adhesive 41 when the cable 30 is pulled can be suppressed, thereby further improving the tensile strength of the cable 30.

[0214] In some embodiments, the first adhesive 41 can form a seal in the dispensing cavity 200a of the first cover 200 to block the connection between the second channel 220 of the first cover 200 and the outside of the shell 10 via the dispensing cavity 200a, the first channel 210 and the second opening 200b.

[0215] like Figures 3 to 7 as well as Fig.12 As shown, the shell body 100 also includes a first side between the first end 101 and the second end 102, and the first side is completely open to form an opening that connects the accommodating cavity 11 with the outside of the shell 10. It should be understood that in other embodiments, the first side may be partially open to form a third opening 108 that connects the accommodating cavity 11 with the outside of the shell 10. That is, the shell body 100 may include a first side between the first end 101 and the second end 102, and a third opening 108 that connects the accommodating cavity 11 with the outside of the shell 10 at the first side. The shell body 100 also includes an edge portion that defines the third opening 108. As shown in FIG. Figure 6 and Fig.12As best shown, the third opening 108 is defined by edge portions 103a of the first side wall 103, 104a of the second side wall 104, and 105a of the third side wall 105 of the housing body 100. The bottom wall 106 of the housing body 100 opposes the third opening 108 in the vertical direction ZZ.

[0216] Fig.15 and Fig.16 The second cover 300 of the housing 10 is shown in detail. Fig.15 and Fig.16 As shown, the second cover body 300 includes a cover top surface 301, a cover bottom surface 302 opposite to the cover top surface 301, a cover side surface 303 extending between the cover top surface 301 and the cover bottom surface 302, and a first flange 304 extending outwardly beyond the cover side surface 303. The first flange 304 can extend from the cover bottom surface 302 or the cover side surface 303. The first flange 304 includes a flange top surface 304a, a flange bottom surface 304b opposite to the flange top surface 304a, and a flange side surface 304c extending between the flange top surface 304a and the flange bottom surface 304b. The flange top surface 304a and the cover top surface 301 face the same direction, and the flange bottom surface 304b and the cover bottom surface 302 face the same direction. The flange top surface 304a is lower than the cover top surface 301.

[0217] like Figure 3 , Figure 7 , Fig.12 and Fig.13 As shown, the second cover 300 is disposed in the third opening 108 of the housing body 100 to close the third opening 108. As described above, one of the multiple walls of the housing 10 is formed by the second cover 300. The cover bottom surface 302 and the flange bottom surface 304b of the second cover 300 face the accommodating cavity 11. The edge portion 103a of the first side wall 103 of the housing body 100, the edge portion 104a of the second side wall 104, and the edge portion 105a of the third side wall 105 form a dispensing groove 60 with the cover side surface 303 and the flange top surface 304a of the second cover 300. The flange side surface 304c can be engaged with the edge portion or adjacent to the edge portion.

[0218] In some embodiments, the electrical connector 1 may include a second adhesive 42 that is filled in the dispensing groove 60 to provide a seal. That is, the second adhesive 42 can block the communication from the accommodating cavity 11 to the outside of the housing 10 via the gap between the second cover 300 and the edge portion of the housing body 100 that defines the third opening 108 (the edge portion 103a of the first side wall 103, the edge portion 104a of the second side wall 104, and the edge portion 105a of the third side wall 105). Through this configuration, the sealing of the electrical connector 1 can be improved. In addition, through this configuration, the connection reliability between the second cover 300 and the housing body 100 can be improved. The second adhesive 42 can also be referred to as a (first) "sealing member" or "sealant".

[0219] The second adhesive 42 may be UV adhesive, silicone, epoxy adhesive or any other suitable adhesive. For example, the second adhesive 42 may be an underfill, such as a silicone underfill (such as polysiloxane, polydimethylsiloxane), an epoxy underfill (such as epoxy resin, epoxy acrylate), a polyurethane underfill (such as polyurethane resin, polyurethane acrylate) or an acrylate underfill (such as acrylate monomer, acrylate copolymer).

[0220] In some embodiments, Figure 8 and Fig. 9 As best shown, the housing body 100 may include a buckle 109 extending from the bottom wall 106 into the accommodating cavity 11. The second cover 300 may include a corresponding engagement feature (not shown) disposed at the cover bottom surface 302. When the second cover 300 is disposed in the third opening 108 of the housing body 100, the buckle 109 of the housing body 100 may engage the corresponding engagement feature of the second cover 300 to fix the second cover 300 in the third opening 108. It should be understood that the present application is not limited thereto, and the second cover 300 may be fixed in the third opening 108 by any suitable fixing mechanism or feature. For example, in other partial embodiments, the second cover 300 may be fixed in the third opening 108 only by the second adhesive 42.

[0221] In some embodiments, Figures 6 to 9 and Figure 12 to Figure 13 As shown, the housing body 100 further includes a second flange 120 protruding into the third opening 108. As an example, the second flange 120 may protrude from the first side wall 103, the second side wall 104, and the third side wall 105 into the third opening 108. As another example, the second flange 120 may protrude from the bottom wall 106 into the third opening 108. Fig.13As best shown, the flange bottom surface 304b of the first flange 304 of the second cover 300 is supported on the second flange 120 of the housing body 100. Through this configuration, a labyrinth seal can be formed at the location of the dispensing groove 60, thereby further improving the sealing performance of the electrical connector 1. Alternatively or additionally, the housing body 100 can also be formed by other suitable structures to support the second cover 300 in the third opening 108.

[0222] In some embodiments, Figures 6 to 9 and Fig.12 As shown, the shell body 100 may further include a partition rib 130 protruding from the bottom wall 106 into the accommodating cavity 11. The partition rib 130 divides the accommodating cavity 11 into a first cavity portion 11a between the first end 101 (or the first cover body 200) and the partition rib 130 and a second cavity portion 11b between the partition rib 130 and the second end 102 (or the first side wall 103). The electrical connection module 20 (i.e., the power connection module 21 and the signal connection module 22) may be located in the second cavity portion 11b, and the cable 30 extends from the outside of the shell 10 through the first cover body 200 and the first cavity portion 11a to the second cavity portion 11b. Fig.12 As best shown, the second cover 300 is disposed above the second cavity portion 11b to separate the second cavity portion 11b from the outside of the housing body 100. In addition, the second cover 300 is engaged with the partition rib 130 and together with the partition rib 130, separates the second cavity portion 11b from the first cavity portion 11a.

[0223] The electrical connector 1 may further include a third adhesive 43, which is filled in the first cavity portion 11a to provide sealing. That is, the third adhesive 43 can block the communication from the second cavity portion 11b to the outside of the housing 10 via the seam between the second cover 300 and the partition rib 130 and the first cavity portion 11a. Through this configuration, the sealing of the electrical connector 1 can be improved. In addition, through this configuration, the connection reliability between the second cover 300 and the housing body 100 can be improved. The third adhesive 43 may also be referred to as a (second) "sealing member" or "sealant".

[0224] The third adhesive 43 may be UV adhesive, silicone, epoxy adhesive or any other suitable type of adhesive. For example, the third adhesive 43 may be an underfill, such as a silicone underfill (such as polysiloxane, polydimethylsiloxane), an epoxy underfill (such as epoxy resin, epoxy acrylate), a polyurethane underfill (such as polyurethane resin, polyurethane acrylate) or an acrylate underfill (such as acrylate monomer, acrylate copolymer).

[0225] In one of these embodiments, Fig.12As shown, the dispensing groove 60 can extend to the first cavity portion 11a and communicate with the first cavity portion 11a to allow the second adhesive 42 and the third adhesive 43 to be applied integrally. That is, the second adhesive 42 and the third adhesive 43 can be applied by a single dispensing process and formed into one body. Through this configuration, the sealing of the electrical connector 1 can be further improved. In addition, through this configuration, the connection reliability between the second cover 300 and the housing body 100 can be further improved.

[0226] As an example, Fig.15 and Fig.16 As shown, the second cover 300 may include a lower flange 305 extending downward from the cover bottom surface 302 or the first flange 304 toward the partition rib 130 of the housing body 100. The lower flange 305 is engaged with the partition rib 130. The third channel 70 may be formed at the portion where the lower flange 305 is engaged with the partition rib 130 (for example, as shown in the figure, the lower flange 305 and the partition rib 130 respectively define a half of each third channel 70), and the cable 30 extends through the third channel 70 to the second cavity portion 11b. Accordingly, the third adhesive 43 can block the communication from the second cavity portion 11b to the outside of the housing 10 via the third channel 70. The electrical connector 1 is shown in the figure as including two third channels 70 to correspond to the power line 31 and the signal line 32 of the cable 30, respectively, so as to allow the power line 31 and the signal line 32 to extend through the third channel 70 to the second cavity portion 11b, respectively. It should be understood that the present application is not limited thereto, and the number of the third holes 70 may be one or more than two. It should also be understood that in other examples, the third holes 70 may be formed in the partition rib 130 .

[0227] In some embodiments, Figures 3 to 5 , Figure 8 and Fig.11 As shown and described above, the power cord 31 is connected to the power connection module 21 at the end 31a of the power cord 31. Specifically, the section of the sheath 34 of the power cord 31 at the end 31a of the power cord 31 is removed so that the wire 33 extends beyond the end 34a of the sheath 34. The end 34a of the sheath 34 is located in the accommodating cavity 11 and Figures 3 to 5 , Figure 8 and Fig.11In the second cavity part 11b of the accommodating cavity 11. If the end 34a of the sheath 34 is not sealed, water vapor may enter the second cavity part 11b along the inside of the sheath 34, for example, when the sheath 34 of the section of the power cord 31 outside the housing 10 of the electrical connector 1 is damaged, or when the end of the sheath 34 opposite to the end 34a is not sealed. In order to prevent this from happening, the electrical connector 1 may include a fourth adhesive 44, which is arranged around the end 34a of the sheath 34 in the accommodating cavity 11 (second cavity part 11b) and forms a seal at the end 34a of the sheath 34. That is, the fourth adhesive 44 can block the communication from the second cavity part 11b to the outside of the housing 10 via the inside of the sheath 34. Through this configuration, the sealing of the electrical connector 1 can be improved. The fourth adhesive 44 can also be called a (third) "sealing member" or "sealant". In some embodiments, similar to the power line 31 , an adhesive may be provided at the end 36 a of the sheath 36 of the signal line 32 to form a seal.

[0228] The fourth adhesive 44 may be UV adhesive, silicone, epoxy adhesive or any other suitable type of adhesive. For example, the fourth adhesive 44 may be an underfill, such as a silicone underfill (such as polysiloxane, polydimethylsiloxane), an epoxy underfill (such as epoxy resin, epoxy acrylate), a polyurethane underfill (such as polyurethane resin, polyurethane acrylate) or an acrylate underfill (such as acrylate monomer, acrylate copolymer).

[0229] In some embodiments, Figure 8 As best shown, the housing body 100 may include a glue spot 140 formed around the end 34a of the sheath 34 of the power cord 31 in the accommodating chamber 11, and the fourth adhesive 44 is filled in the glue spot 140. By this configuration, the application of the fourth adhesive 44 can be facilitated.

[0230] In some embodiments, Figure 3 , Figure 7 and Fig. 9As shown, the electrical connector 1 may include a clamp 400. The clamp 400 is installed on the sheath 34 of the power cord 31, and fixes the power cord 31 in the accommodating chamber 11 (the second chamber part 11b). Through this configuration, on the one hand, by fixing the power cord 31, the application of the fourth adhesive 44 can be facilitated, and the fourth adhesive 44 can be prevented from shifting due to the shaking of the power cord 31; on the other hand, the tensile strength of the power cord 31 can be improved, thereby improving the vibration resistance; on the other hand, by installing the clamp 400 on the sheath 34 of the power cord 31, the sheath 34 can be tightened, thereby further enhancing the seal. These can improve the reliability of the electrical connector 1. The power cord 31 can be fixed in the accommodating chamber 11 (the second chamber part 11b) by using the clamp 400 before applying the fourth adhesive 44.

[0231] like Fig.10 and Fig.11 As best shown, the clamp 400 includes an annular body 401 mounted on the jacket 34 of the power cord 31 and a tab 402 extending outwardly from the annular body 401. Figure 6 and Figure 7 As best shown, the housing body 10 may include a receiving portion 150 formed in the accommodating cavity 11, and the tab 402 of the clamp 400 is received in the receiving portion 150 to fix the first cable 31 in the accommodating cavity 11. For example, the clamp 400 may be formed of a metal material. It should be understood that the clamp 400 may be in any other suitable form.

[0232] In some other embodiments, similar to the power line 31 , a clamp may be provided for the signal line 32 .

[0233] By using at least one of the above configurations, the reliability of the electrical connector 1 can be improved.

[0234] Although the specific configuration of the electrical connector 1 is described above in conjunction with the example that the electrical connector 1 is an Ethernet connector, it should be understood that the type of the electrical connector 1 is not limited thereto. The electrical connector 1 may be other types of electrical connectors and may be used for any other applications.

[0235] It should be understood that the above configurations may be used alone or in any suitable combination.The foregoing summary is provided by way of illustration and is not meant to be limiting.

[0236] As an example, although it is described above that the first cover 200 is a component separate from the housing body 100 and is installed on the housing body 100, it should be understood that the first cover 200 can be formed integrally with the housing body 100. That is, the first cover 200 is one of the multiple walls of the housing body 100. In this case, the first cover 200 can still be formed with the aforementioned glue dispensing cavity 200a, the first channel 210, the second channel 220 and the second opening 200b, and a protrusion and a recess similar to the protrusion 101c and the recess 101d can be formed on the inner wall of the glue dispensing cavity 200a of the first cover 200, thereby providing the aforementioned various benefits.

[0237] As another example, the second cover 300 can be used alone to cooperate with the shell body 100 to provide the aforementioned various benefits. Therefore, the present application also proposes an electrical connector, which includes: a shell, the shell including: a shell body, the shell body including a plurality of walls enclosing a receiving cavity, an opening at a first side of the shell body connecting the receiving cavity with the outside of the shell, and an edge portion defining the opening; and a second cover, the second cover including a cover top surface, a cover bottom surface opposite to the cover top surface, a cover side surface extending between the cover top surface and the cover bottom surface, and a first flange extending outward beyond the cover side surface, the first flange including a flange top surface and a flange bottom surface opposite to the flange top surface, the flange top surface being lower than the cover top surface; an electrical connection module at least partially disposed in the receiving cavity; and a cable, the cable extending from the outside of the shell through the first cover in the plurality of walls into the receiving cavity, and being connected to the electrical connection module at the end of the cable. The second cover is arranged in the opening of the shell body to close the opening, the cover bottom surface and the first flange bottom surface face the accommodating cavity, and the edge portion of the shell body and the cover side surface and the flange top surface of the second cover form a dispensing groove. The electrical connector also includes a first adhesive, which is filled in the dispensing groove to form a seal.

[0238] As another example, the fourth adhesive 44 and the clamp 400 can be used alone or in combination to cooperate with the cable 30 to provide the aforementioned various benefits. Therefore, the present application also proposes an electrical connector, which includes: a housing, the housing including a plurality of walls enclosing a receiving cavity; an electrical connection module at least partially disposed in the receiving cavity; a cable, the cable extending from the outside of the housing through a first cover in the plurality of walls into the receiving cavity, and connected to the electrical connection module at the end of the cable, the cable including a wire and a sheath surrounding the wire, the section of the sheath at the end of the cable being removed so that the wire extends beyond the end of the sheath, and the end of the sheath is located in the receiving cavity; and an adhesive, the adhesive is disposed in the receiving cavity around the end of the sheath, and forms a seal at the end of the sheath. Accordingly, the clamp can be arranged in the manner described above.

[0239] Although one dispensing cavity 200 a is shown, it should be understood that there may be multiple dispensing cavities 200 a to correspond to the power lines 31 and the signal lines 32 , respectively.

[0240] It should also be understood that the aforementioned directions and orientation relationships are merely exemplary, and the present application is not limited thereto.

[0241] As an example, although the above description describes that the section of the cable 30 located in the dispensing cavity 200a extends along the transverse direction XX, it should be understood that the section of the cable 30 located in the dispensing cavity 200a can extend along any other suitable direction. For example, the section can be bent in the dispensing cavity 200a.

[0242] As another example, although it is described above that the second opening 200b of the first cover body 200 extends through the third portion 203 of the first cover body 200 to the dispensing cavity 200a along the longitudinal direction YY perpendicular to the transverse direction XX, it should be understood that the second opening 200b of the first cover body 200 can extend along other directions perpendicular to the transverse direction XX, or along a direction that is not perpendicular to the transverse direction XX.

[0243] As another example, although it is described above that the first portion 201 and the second portion 202 of the first cover 200 are opposite to each other in the transverse direction XX, it should be understood that the first portion 201 and the second portion 202 of the first cover 200 can be arranged in any other suitable orientation relationship.
