The bottom wall 106 extends in the longitudinal direction Y-Y between the second side wall 104 and the third side wall 105. The first sidewall 103 connects the second sidewall 104, the third sidewall 105 and the bottom wall 106. The first, second, third and bottom walls 103, 104, 105, 106 of the housing body 100 may form four of the plurality of walls of the housing 10. Further, as will be described in detail below, the first cover 200 may form one of the walls of the case 10, and the second cover 300 may form another of the walls of the case 10. The first side wall 103, the second side wall 104, the third side wall 105, the bottom wall 106, the first cover 200, and the second cover 300 of the housing body 100 enclose the accommodating chamber 11.

In some embodiments, the case body 100 may include a mounting portion 12 protruding outward 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, with a fastener such as a screw or a pin.

The case body 100, the first cover 200, and the second cover 300 may be made of any suitable material. For example, the case body 100, the first cover 200, and the second cover 300 may be made of an insulating material.

With continued reference to fig. 3-7 and 12, the receiving chamber 11 is located within the housing body 100. The housing body 100 includes a first opening 107 (fig. 5) in communication with the receiving cavity 11 at the first end 101 to allow the cable 30 to extend into the receiving cavity 11 via the first opening 107.

The first cover 200 is mounted to the first end 101 of the housing body 100 to close the first opening 107. As described above, one of the walls of the case 10 is formed by the first cover 200. Fig. 14 is a perspective view of the first cover 200. As shown in fig. 14, the first cover 200 (or referred to as a "first wall" of the housing 10) includes a dispensing chamber 200a formed in the first cover 200, a first duct 210 extending from the dispensing chamber 200a through a first portion 201 of the first cover 200 to the outside of the housing 10, and a second duct 220 extending from the dispensing chamber 200a through a second portion 202 of the first cover 200 to the receiving chamber 11.

As shown in fig. 1 to 5, 7, and 11 to 12, the cable 30 includes a power supply line 31 configured to transmit electric power and a signal line 32 configured to transmit a signal. The sections of the power cord 31 and the signal cord 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 that 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 may be devoid of a sleeve.

The power cord 31 (may also be referred to as a "first cable") includes a wire 33 and a sheath 34 surrounding the wire 33. The power line 31 is shown as having four wires 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 such that the wires 33 extend beyond the end 34a of the sheath 34. The wire 33 may include a conductor 33a and an insulator 33b surrounding the conductor. A section of the insulator 33b corresponding to the connection portion of the conductor 33a with the power supply connection module 21 is removed. This enables the power cord 31 to be ready for connection to the power connection module 21.

Similar to the power cord 31, the signal cord 32 (which may also be referred to as a "second cable") includes a wire 35 and a sheath 36 surrounding the wire 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 wire 32 is removed such that the wire 35 extends beyond the end 36a of the sheath 36. The wire 35 may include a conductor 35a and an insulator 35b surrounding the conductor. A 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 for connection to the signal connection module 22. In some embodiments, the signal line 32 may include a shield (not shown) disposed at the end 36a of the sheath 36.

The first cover 200 is shown in fig. 14 as including two first duct 210 to correspond to the power line 31 and the signal line 32 of the cable 30, respectively, thereby allowing the power line 31 and the signal line 32 to extend from the outside of the housing 10 into the dispensing chamber 200a, respectively, via the corresponding first duct 210. In addition, the first cover 200 is also shown in fig. 14 to include two second tunnels 220 to correspond to the power line 31 and the signal line 32 of the cable 30, respectively, thereby allowing the power line 31 and the signal line 32 to extend from the dispensing chamber 200a into the receiving chamber 11 via the corresponding second tunnels 220, respectively. It should be understood that the present application is not limited thereto, and the number of the first and second cells 210 and 220 may be one or more than two.

As shown in fig. 2 to 9, the electrical connection module 20 includes a power supply connection module 21 configured to transmit power and a signal connection module 22 configured to transmit signals.

The power connection module 21 may include a main body 21a and a power terminal (not shown) held by the main body 21 a. The power supply terminal may be formed of a conductive material. The power terminal may include a mating end (not labeled), a mounting end 21b opposite the mating end, and an intermediate portion extending between the mating end and the mounting end. The mating ends of the power terminals are configured for connection with conductors 33a of respective wires 33 of the power cord 31. The mounting end 21b of the power terminal may be configured for mounting to a circuit board (not shown) such as a motherboard of a vehicle lidar. As shown in fig. 2 and 4 to 7, in a state where the power supply connection module 21 is mounted to the housing 10, the main body 21a is located in the accommodation chamber 11, and the mounting end 21b extends through the bottom wall 106 of the housing main body 100 to the outside of the housing main body 100 for mounting to a 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 entirely within the receiving cavity 11. That is, the power connection module 21 may be at least partially disposed in the receiving chamber 11. It should also be understood that the specific form of the power connection module 21 is not limited thereto.

The signal connection module 22 may include a main body 22a and signal terminals (not shown) held by the main body 22 a. The signal terminals may be formed of a conductive material. The signal terminals may include a mating end (not labeled), a mounting end 22b opposite the mating end, and an intermediate portion extending between the mating end and the mounting end. The mating ends of the signal terminals are configured for connection with conductors 35a of respective ones of wires 35 of signal lines 32. The mounting end 22b of the signal terminal may be configured for mounting to a circuit board (not shown) such as a motherboard of a vehicle lidar. As shown in fig. 2 and 4 to 7, in a state in which the signal connection module 22 is mounted to the housing 10, the main body 22a is located in the accommodation chamber 11, and the mounting end 22b extends through the bottom wall 106 of the housing main body 100 to the outside of the housing main body 100 for mounting to a circuit board. It should be understood that the present application is not so limited, and in some embodiments, the signal connection module 22 may be located entirely within the receiving chamber 11. That is, the signal connection module 22 may be at least partially disposed in the receiving chamber 11. It should also be understood that the particular form of the signal connection module 22 is not so limited.

As shown in fig. 4, the cable 30 extends from the outside of the case 10 through the first duct 210, the dispensing chamber 200a, and the second duct 220 of the first cover 200 into the receiving chamber 11, and is connected to the electrical connection module 20 at an end of the cable 30. Specifically, the power cord 31 extends from the outside of the housing 10 through the corresponding first duct 210, the dispensing chamber 200a, and the corresponding second duct 220 of the first cover 200 into the receiving chamber 11, and is connected to the power connection module 21 at the end 31a of the power cord 31. The signal lines 32 extend from the outside of the housing 10 through the respective first portholes 210, the dispensing chamber 200a and the respective second portholes 220 of the first cover 200 into the receiving chamber 11 and are connected to the signal connection module 22 at the ends 32a of the signal lines 32.

In some embodiments, the cable 30 may be extended through the first duct 210, the dispensing chamber 200a, and the second duct 220 of the first cover 200 before the first cover 200 is mounted to the first end 101 of the housing body 100. Alternatively, the cable 30 may be extended through the first duct 210, the dispensing chamber 200a, and the second duct 220 of the first cover 200 after the first cover 200 is mounted to the first end 101 of the housing body 100.

In some embodiments, the cable 30 may be connected to the electrical connection module 20 before the electrical connection module 20 is mounted to 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 to the housing body 100.

In some embodiments, the electrical connector 1 may include a first adhesive 41. As best shown in fig. 1, 7 and 12, the first adhesive 41 is filled in the dispensing cavity 200a of the first cover 200 and disposed around the sections 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 with respect to the first cover 200. The first adhesive 41 may be applied after the first cover 200 is mounted to the first end 101 of the housing body 100 and the cable 30 extends through the first duct 210, the dispensing chamber 200a, and the second duct 220 of the first cover 200. The cable 30 is fixed to the first cover 200 by the first adhesive 41, so that the tensile strength of the cable 30 can be improved, and the vibration resistance of the electrical connector 1 can be improved, thereby improving the reliability of the electrical connector 1. Further, compared to fixing the cable 30 with the SR (strain relief) overmold, fixing the cable 30 with respect to the first cover 200 with the first adhesive 41 can reduce the volume of the electrical connector 1 and can reduce the manufacturing process complexity and manufacturing cost of the electrical connector 1. The first adhesive 41 may also be referred to as a "fixing member" or a "fixing glue".

The first adhesive 41 may be UV glue, silicone gel, epoxy glue or any other suitable type of adhesive. For example, the first adhesive 41 may be an underfill, such as a silicone-based underfill (e.g., polysiloxane, polydimethylsiloxane), an epoxy-based underfill (e.g., epoxy resin, epoxy acrylate), a polyurethane-based underfill (e.g., polyurethane resin, polyurethane acrylate), or an acrylate-based underfill (e.g., acrylate monomer, acrylate copolymer).

In some embodiments, the first cover 200 may be mounted to the housing body 100 by any suitable means, such as snap fit, latching mechanism, heat welding, etc. For example, the housing body 100 may be provided with a snap structure (not shown) at the first end 101 and the first cover 200 may be provided with a mating snap structure (not shown). The snap-fit structure of the housing body 100 and the mating snap-fit structure of the first cover 200 may cooperate to reliably mount the first cover 200 to the first end 101 of the housing body 100.

As best shown in fig. 4 to 6, in a state in which the first cover 200 is mounted to the first end 101 of the housing main body 100, the second portion 202 of the first cover 200 is adjacent to the accommodating chamber 11, and the first face 202a of the second portion 202 of the first cover 200 faces the accommodating chamber 11.

In some embodiments, the second portion 202 of the first cover 200 includes a slot (not shown) extending from the first face 202a through the second portion 202 to the dispensing chamber 200 a. A portion 101a (fig. 5) of the first end 101 of the housing body 100 may be inserted into the slot. The first adhesive 41 may be engaged with the portion 101a of the first end 101 of the housing body 100. As one example, the first adhesive 41 may extend into a slot of the second portion 202 to engage the portion 101a of the first end 101 of the housing body 100. As another example, the first surface 101b of the portion 101a of the first end 101 of the case body 100 may be exposed in the dispensing cavity 200a of the first cover 200, and the first adhesive 41 may be disposed on the first surface 101 b. The first adhesive 41 is bonded to the aforementioned portion 101a of the first end 101 of the housing main body 100, so that the connection strength between the first cover 200 and the housing main body 100 can be improved to improve the vibration resistance of the electrical connector 1. It should be appreciated that in other partial embodiments, the first cover 200 may be held to the first end 101 of the housing body 100 by only the first adhesive 41 engaging the aforementioned portion 101a of the first end 101 of the housing body 100.

Alternatively, in an embodiment in which the first surface 101b of the aforementioned portion 101a of the first end 101 of the housing body 100 is exposed in the dispensing chamber 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 chamber 200 a. The first adhesive 41 may be provided to the first surface 101b and engaged with the protrusion 101c. In this way, the connection strength between the first cover 200 and the case main body 100 can be further improved. In addition, 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 one example, as shown, the protrusion 101c may be configured as a barb.

Alternatively or additionally, in an embodiment in which 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 recess 101d recessed from the first surface 101b into the aforementioned portion 101 a. The first adhesive 41 may be provided on the first surface 101b and filled in the concave portion 101d. In this way, the connection strength between the first cover 200 and the case main body 100 can be further improved. In addition, 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.

In some embodiments, as best shown in fig. 4, a section of the cable 30 located in the dispensing cavity 200a may extend along the lateral direction X-X. The first cover 200 may include a second opening 200b, the second opening 200b extending from the outside of the case 10 through the third portion 203 of the first cover 200 to the dispensing chamber 200a along a longitudinal direction Y-Y perpendicular to the transverse direction X-X to allow the first adhesive 41 to be filled into the dispensing chamber 200a through the second opening 200 b. With this configuration, it is possible to facilitate filling of the first adhesive 41 in the dispensing chamber 200a and to dispose around the section of the cable 30 located in the dispensing chamber 200 a. In addition, the second opening 200b can be used as an inspection window to facilitate inspection of the filling of the first adhesive 41 in the dispensing cavity 200 a.

In one of these embodiments, the first portion 201 and the second portion 202 of the first cover 200 may be opposite to each other in the lateral direction X-X and spaced apart from each other by the dispensing chamber 200a, and the third portion 203 joins the first portion 201 and the second portion 202. The first and second cells 210 and 220 may extend along the lateral direction X-X, respectively. The cross section of the dispensing chamber 200a perpendicular to the transverse direction X-X may be greater than the cross section of the first porthole 210 perpendicular to the transverse direction X-X and may be greater than the cross section of the second porthole 220 perpendicular to the transverse direction X-X. With this configuration, the first adhesive 41 can be reliably joined with the inner wall of the dispensing chamber 200a, thereby improving the tensile strength of the cable 30. In some examples, the first cell 210 and the second cell 220 are aligned with each other in the lateral direction X-X. It should be understood that the present application is not limited thereto, and that the first and second cells 210 and 220 may be partially or completely staggered from each other in the transverse direction X-X.

Alternatively or additionally, in embodiments in which 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 facing away from the second opening 200 b. The first adhesive 41 may be disposed on the first surface 101b and bonded to the first surface 101 b. As best shown in fig. 5 and 6, the first cover 200 may further include a fourth portion 204, the fourth portion 204 and the third portion 203 being opposite each other in the longitudinal direction Y-Y and being spaced apart from each other by the dispensing chamber 200 a. The fourth portion 204 may include a second face 204a facing the dispensing chamber 200a and a groove 204b recessed from the second face 204a into the fourth portion 204 and communicating with a 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 protruding from the first surface 101b into the dispensing cavity 200 a. The first adhesive 41 may be provided to the first surface 101b and engaged with the protrusion 101c. For example, the protrusion 101c may be configured as a barb. Alternatively or additionally, in some embodiments, as described above, the aforementioned portion 101a of the first end 101 of the housing body 100 may include a recess 101d recessed into the aforementioned portion 101a from the first surface 101 b. The first adhesive 41 may be provided on the first surface 101b and filled in the concave portion 101d. By at least one of these configurations, the connection strength between the first cover 200 and the case main body 100 can be further improved. In addition, 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.

In some embodiments, the first adhesive 41 may form a seal in the dispensing cavity 200a of the first cover 200 to block the communication of the second duct 220 of the first cover 200 to the outside of the case 10 via the dispensing cavity 200a, the first duct 210 and the second opening 200 b.

As shown in fig. 3 to 7 and 12, the housing body 100 further includes a first side between the first end 101 and the second end 102, which is completely opened to form an opening communicating the accommodating chamber 11 with the outside of the housing 10. It should be appreciated that in other partial embodiments, the first side may be partially open to form a third opening 108 that communicates the receiving chamber 11 with the exterior of the housing 10. That is, the housing body 100 may include a first side between the first end 101 and the second end 102, and a third opening 108 communicating the accommodating chamber 11 with the outside of the housing 10 at the first side. The housing body 100 also includes a rim portion defining a third opening 108. As best shown in fig. 6 and 12, the third opening 108 is defined by the rim portion 103a of the first side wall 103, the rim portion 104a of the second side wall 104, and the rim portion 105a of the third side wall 105 of the housing body 100. The bottom wall 106 of the housing body 100 is opposite to the third opening 108 in the vertical direction Z-Z.

Fig. 15 and 16 show the second cover 300 of the housing 10 in detail. As shown in fig. 15 and 16, the second cover 300 includes a cover top surface 301, a cover bottom surface 302 opposite 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 may extend from the lid bottom surface 302 or the lid side surface 303. The first flange 304 includes a flange top surface 304a, a flange bottom surface 304b opposite the flange top surface 304a, and a flange side surface 304c extending between the flange top surface 304a and the flange bottom surface 304 b. The flange top surface 304a and the cover top surface 301 face in the same direction, and the flange bottom surface 304b and the cover bottom surface 302 face in the same direction. The flange top surface 304a is lower than the cover top surface 301.

As shown in fig. 3, 7, 12 and 13, the second cover 300 is disposed in the third opening 108 of the case body 100 to close the third opening 108. As described above, one of the walls of the case 10 is formed by the second cover 300. The cover bottom surface 302 and the flange bottom surface 304b of the second cover body 300 face toward the accommodating chamber 11. The rim portion 103a of the first side wall 103, the rim portion 104a of the second side wall 104, and the rim portion 105a of the third side wall 105 of the case body 100 form the dispensing groove 60 with the cap side surface 303 and the flange top surface 304a of the second cap body 300. Flange side 304c may engage with or be immediately adjacent to the rim portion.

In some embodiments, the electrical connector 1 may include a second adhesive 42, the second adhesive 42 being filled in the dispensing groove 60 to provide a seal. That is, the second adhesive 42 can block communication from the housing chamber 11 to the outside of the housing 10 via the gap between the second cover 300 and the rim portion of the housing main body 100 defining the third opening 108 (the rim portion 103a of the first side wall 103, the rim portion 104a of the second side wall 104, and the rim portion 105a of the third side wall 105). With this configuration, the sealability of the electrical connector 1 can be improved. Further, with this arrangement, the connection reliability between the second cover 300 and the housing main body 100 can be improved. The second adhesive 42 may also be referred to as a (first) "sealing member" or "sealant".

The second adhesive 42 may be a UV adhesive, a silicone adhesive, an epoxy adhesive, or any other suitable type of adhesive. For example, the second adhesive 42 may be an underfill, such as silicone-based underfill (e.g., polysiloxane, polydimethylsiloxane), epoxy-based underfill (e.g., epoxy resin, epoxy acrylate), polyurethane-based underfill (e.g., polyurethane resin, polyurethane acrylate), or acrylate-based underfill (e.g., acrylate monomer, acrylate copolymer).

In some embodiments, as best shown in fig. 8 and 9, the housing body 100 may include a catch 109 extending from the bottom wall 106 into the receiving cavity 11. The second cover 300 may include corresponding engagement features (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 catch 109 of the housing body 100 may engage a corresponding engagement feature of the second cover 300 to secure the second cover 300 in the third opening 108. It should be appreciated that the present application is not so limited, and that the second cover 300 may be secured in the third opening 108 by any suitable securing mechanism or feature. For example, in other embodiments, the second cover 300 may be secured in the third opening 108 by only the second adhesive 42.

In some embodiments, as shown in fig. 6-9 and 12-13, the housing body 100 further includes a second flange 120 protruding into the third opening 108. As one example, the second flange 120 may protrude from the first, second, and third sidewalls 103, 104, 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. As best shown in fig. 13, 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 main body 100. With this configuration, a labyrinth seal can be formed at the position of the dispensing groove 60, thereby further improving the sealability of the electrical connector 1. Alternatively or additionally, the housing body 100 may also be formed by other suitable structures to support the second cover 300 in the third opening 108.

In some embodiments, as shown in fig. 6 to 9 and 12, the housing body 100 may further include a partition rib 130 protruding from the bottom wall 106 into the accommodation chamber 11. The partition rib 130 divides the receiving chamber 11 into a first chamber portion 11a between the first end 101 (or the first cover 200) and the partition rib 130 and a second chamber portion 11b between the partition rib 130 and the second end 102 (or the first sidewall 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 housing 10 through the first cover 200 and the first cavity portion 11a into the second cavity portion 11b. As best shown in fig. 12, the second cover 300 is disposed above the second chamber portion 11b to separate the second chamber portion 11b from the outside of the housing main body 100. Further, the second cover 300 is engaged with the partition rib 130, and separates the second chamber portion 11b from the first chamber portion 11a together with the partition rib 130.

The electrical connector 1 may further comprise a third adhesive 43, which third adhesive 43 is filled in the first cavity portion 11a to provide a seal. That is, the third adhesive 43 can block communication from the second cavity portion 11b to the outside of the case 10 via the seam between the second cover 300 and the partition rib 130 and the first cavity portion 11 a. With this configuration, the sealability of the electrical connector 1 can be improved. Further, with this arrangement, the connection reliability between the second cover 300 and the housing main body 100 can be improved. The third adhesive 43 may also be referred to as a (second) "sealing member" or "sealant".

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

In one of these embodiments, as shown in fig. 12, a dispensing recess 60 may 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 integrally applied. That is, the second adhesive 42 and the third adhesive 43 can be applied by a single dispensing process and formed as one body. With this configuration, the sealability of the electrical connector 1 can be further improved. Further, with this arrangement, the connection reliability between the second cover 300 and the housing main body 100 can be further improved.

As an example, as shown in fig. 15 and 16, 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 case body 100. The lower flange 305 engages the partition rib 130. The third tunnels 70 may be formed at portions where the lower flange 305 is engaged with the partition ribs 130 (e.g., as shown, the lower flange 305 and the partition ribs 130 respectively define half portions of each third tunnel 70), and the cable 30 extends through the third tunnels 70 into the second cavity portion 11 b. Accordingly, the third adhesive 43 can block communication from the second chamber portion 11b to the outside of the housing 10 via the third duct 70. The electrical connector 1 is shown in the figure as comprising two third portholes 70 to correspond to the power cord 31 and the signal cord 32 of the cable 30, respectively, allowing the power cord 31 and the signal cord 32 to extend through the third portholes 70 into the second cavity portion 11b, respectively. It should be understood that the present application is not limited thereto, and the number of third cells 70 may be one or more than two. It should also be appreciated that in other partial examples, the third portholes 70 may be formed in the partition rib 130.

In some embodiments, as shown in fig. 3-5, 8, and 11 and as described above, the power cord 31 is connected to the power connection module 21 at an 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 such that the lead 33 extends beyond the end 34a of the sheath 34. The end 34a of the sheath 34 is located in the receiving chamber 11 and in the second chamber portion 11b of the receiving chamber 11 in fig. 3 to 5, 8 and 11. If the end 34a of the sheath 34 is not sealed, moisture may enter the second cavity portion 11b along the inside of the sheath 34, for example, in the event of breakage of the sheath 34 of a section of the power cord 31 outside the housing 10 of the electrical connector 1, or in the event that the end of the sheath 34 opposite to the end 34a is not sealed. To prevent this, the electrical connector 1 may include a fourth adhesive 44, which fourth adhesive 44 is disposed around the end 34a of the sheath 34 in the accommodation chamber 11 (the second chamber portion 11 b) and forms a seal at the end 34a of the sheath 34. That is, the fourth adhesive 44 can block communication from the second chamber portion 11b to the outside of the housing 10 via the inside of the sheath 34. With this configuration, the sealability of the electrical connector 1 can be improved. The fourth adhesive 44 may also be referred to as a (third) "sealing member" or "sealant". In some embodiments, similar to the power cord 31, an adhesive may be provided at the end 36a of the jacket 36 of the signal cord 32 to form a seal.

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

In some embodiments, as best shown in fig. 8, the case body 100 may include a dispensing part 140 formed around the end 34a of the sheath 34 of the power cord 31 in the receiving chamber 11, and the fourth adhesive 44 is filled in the dispensing part 140. With this configuration, application of the fourth adhesive 44 can be facilitated.

In some embodiments, as shown in fig. 3, 7 and 9, the electrical connector 1 may include a clip 400. The clip 400 is mounted on the sheath 34 of the power cord 31, and fixes the power cord 31 in the housing chamber 11 (the second chamber portion 11 b). With this configuration, on the one hand, by fixing the power supply line 31, the application of the fourth adhesive 44 can be facilitated, and the fourth adhesive 44 can be prevented from being displaced due to the shake of the power supply line 31; on the other hand, the tensile strength of the power cord 31 can be improved, thereby improving vibration resistance; on the other hand, by attaching the clip 400 to the sheath 34 of the power cord 31, the sheath 34 can be pinched, thereby further enhancing the seal. These can improve the reliability of the electrical connector 1. The power cord 31 may be fixed in the housing chamber 11 (the second chamber portion 11 b) using the clip 400 before the fourth adhesive 44 is applied.

As best shown in fig. 10 and 11, the clip 400 includes an annular body 401 mounted on the sheath 34 of the power cord 31 and a tab 402 extending outwardly from the annular body 401. As best shown in fig. 6 and 7, the housing body 10 may include a receiving portion 150 formed in the receiving cavity 11, and a tab 402 of the clip 400 is received in the receiving portion 150 to fix the first cable 31 in the receiving cavity 11. For example, the clip 400 may be formed of a metallic material. It should be appreciated that the clip 400 may take any other suitable form.

In other embodiments, similar to the power cord 31, a clip may be provided to the signal cord 32.

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

Although the specific configuration of the electrical connector 1 is described above in connection with the example in which the electrical connector 1 is an ethernet connector, it should be understood that the type of electrical connector 1 is not limited thereto. The electrical connector 1 may be another type of electrical connector and may be used for any other application.

It should be appreciated 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 intended to be limiting.

As one example, although it is described above that the first cover 200 is a separate member from the housing body 100 and is mounted to the housing body 100, it should be understood that the first cover 200 may be integrally formed with the housing body 100. That is, the first cover 200 is one of the walls of the housing main body 100. In this case, the first cover 200 may still be formed with the aforementioned dispensing chamber 200a, the first duct 210, the second duct 220, and the second opening 200b, and protrusions and recesses similar to the protrusions 101c and recesses 101d may be formed on the inner wall of the dispensing chamber 200a of the first cover 200, thereby providing the aforementioned various benefits.

As another example, the second cover 300 may be used alone to cooperate with the housing body 100 to provide the aforementioned various benefits.

It should also be understood that the foregoing directions and orientation relationships are merely exemplary and the application is not limited thereto.

As one example, while the section of the cable 30 located in the dispensing cavity 200a is described above as extending in the lateral direction X-X, it should be understood that the section of the cable 30 located in the dispensing cavity 200a may extend in any other suitable direction. For example, the section may be curved in the dispensing chamber 200 a.

As another example, although the second opening 200b of the first cover 200 is described above as extending through the third portion 203 of the first cover 200 to the dispensing cavity 200a along the longitudinal direction Y-Y perpendicular to the transverse direction X-X, it should be understood that the second opening 200b of the first cover 200 may extend along other directions perpendicular to the transverse direction X-X or along directions other than perpendicular to the transverse direction X-X.

As yet another example, while the first portion 201 and the second portion 202 of the first cover 200 are described above as being opposed to one another in the transverse direction X-X, it should be appreciated that the first portion 201 and the second portion 202 of the first cover 200 may be disposed in any other suitable orientation.
