Description

Technical Field

[0001] The present invention relates to a connector assembly, and more particularly to a connector assembly for providing pluggable module insertion. Background Art

[0002] Chinese Utility Model Patent CN210092418 U discloses a connector. In this case, the outer housing defines four linearly arranged accommodation cavities through a third wall portion, and the front end of the accommodation cavity is divided into an upper insertion cavity and a lower insertion cavity by a spacer assembly. Elastic pins are provided at the bottom of the outer housing. In addition, in this case, the outer housing is only fixed to the through hole of the PCB board through the elastic pins to be fixed to the PCB board. The holding force of the outer housing and the effect of resisting the insertion force still need to be strengthened. Especially when the outer housing is arranged upright on the circuit board, the height increases and the bottom surface decreases, and the fixing effect and strength will be more insufficient.

[0003] In addition, the heat dissipation mechanism disclosed in this case mainly achieves heat dissipation through the heat dissipation holes in the first wall portion and the second wall portion of the outer housing. Therefore, it still mainly relies on the wall portions around the outer housing for heat dissipation. As for the internal heat dissipation mechanism, there is still room for further improvement. For example, although it discloses that the spacer assembly includes an upper spacer and a lower spacer separated by a gap, however, the front ends of the upper spacer and the lower spacer are in contact with each other to form a closed state, and the heat dissipation air flow cannot enter between the upper spacer and the lower spacer from the front end of the spacer assembly, and the third wall portion used for partitioning also lacks a heat dissipation function. Summary of the Invention

[0004] Therefore, an object of the present invention is to provide a connector assembly that can strengthen the structural holding force and resistance to insertion force between the outer housing and the substrate.

[0005] Thus, the connector assembly of the present invention includes a guiding shield and a plurality of support seats. The guiding shield includes an outer housing and a plurality of support seat fixing portions formed at the bottom end of the outer housing. Each support seat fixing portion includes a first engaging portion and a first supporting portion.

[0008] In some embodiments, each support base fixing portion further includes a bottom notch, and an upwardly concave bottom notch is formed between the bottom edge of each support base fixing portion and the bottom edge of the housing. The support table portion extends inward relative to the housing into the bottom notch and is supported on the bottom edge at the lower end of the support base fixing portion.

[0009] In some embodiments, each support table portion has an inner surface facing the interior of the housing, and the inner surface of the support table portion does not extend beyond the inner surface of the housing. One end of the plurality of fixing pins located inside the housing does not extend beyond the inner surface of the housing.

[0010] In some embodiments, each support base further includes a body, a fastener fitting hole located in the body, and a standing bracket located at the bottom end of the body.

[0015] An object of the present invention is to provide a connector assembly capable of improving the heat dissipation effect of the housing.

[0016] The connector assembly of the present invention provides pluggable module insertion. The connector assembly includes a substrate and a guiding shield. The substrate is formed with a plurality of air flow through holes. The guiding shield is disposed on the substrate and includes a housing, a longitudinal partition member, and a transverse partition member. The housing includes two end walls facing each other longitudinally and two side walls facing each other transversely. The longitudinal partition member extends longitudinally and is assembled between the two end walls and includes two longitudinally spaced partition plates, and an air flow channel formed between the two longitudinally spaced partition plates and communicating with the air flow through holes. The transverse partition member includes two transversely spaced partition plates, and an air flow channel formed between the two transversely spaced partition plates and communicating with the air flow through holes.

[0017] In some embodiments, a bottom air flow gap is formed between the longitudinal partition member and the substrate; a bottom air flow gap is formed between the transverse partition member and the substrate.

[0018] In some embodiments, the bottom of the longitudinal partition member is provided with a raised bump. By means of the raised bump, the longitudinal partition member is raised above the substrate, so that the bottom air flow gap is formed between the longitudinal partition member and the substrate.

[0019] In some embodiments, a bottom air flow gap is formed between the bottom end of the housing and the substrate.

[0020] In some embodiments, the bottom end of the housing has retaining feet and raised bumps. The retaining feet are used to be fixed to the substrate. By means of the raised bumps, the housing is raised above the substrate, so that the bottom air flow gap is formed between the housing and the upper surface of the substrate.

[0021] In some embodiments, the longitudinal partition member includes a pair of longitudinally spaced partition plates from each other, and a front end plate extending longitudinally between the front ends of the two longitudinally spaced partition plates. The air flow channel is defined between the two longitudinally spaced partition plates. The front end plate has a plurality of air flow holes and covers most of the front end opening of the air flow channel.

[0027] In some embodiments, part of the side support piece is integrally connected to the two transverse partition plates.

[0028] One effect of the present invention is that through the provision of the support seat fixing part of the housing and the support seat, the structural holding force and resistance to insertion force of the housing are enhanced, and the support seat does not affect the insertion of the pluggable module, so the object of the present invention can be truly achieved.

[0029] Another effect of the present invention is that through the formation of the air flow through holes in the substrate and its connection to a plurality of plugging channels, the heat dissipation effect of the housing is effectively improved. Further, by using the air flow channels of the longitudinal partition member and the transverse partition member, and the air flow holes of the longitudinal partition member, the front end opening of the transverse partition member and the plurality of bottom air flow gaps, the air flow is provided to flow through the longitudinal partition member and the transverse partition member, and the longitudinal partition member and the transverse partition member also have the effect of heat dissipation.

[0142] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

[0143] Referring to Figures 1 to 5 , an embodiment of the connector assembly of the present invention includes a substrate 1, a guiding shielding cover 2a, a plurality of sockets 3 ( Figure 2 only one is shown), and a plurality of supporting seats 4. The guiding shielding cover 2a is assembled upright relative to the substrate 1 and extends up and down in a height direction H relative to the substrate 1. The sockets 3 are provided on the substrate 1 to provide pluggable modules 3a to be plugged in. And in the following embodiments, the front end herein refers to the end of the guiding shielding cover 2a facing upward and away from the substrate 1 in the drawing, and the bottom end refers to the end of the guiding shielding cover 2a facing downward and close to the substrate 1. The supporting seats 4 are assembled at the bottom of the guiding shielding cover 2a for fixing and supporting the guiding shielding cover 2a on the substrate 1. Among them, through the heat dissipation mechanism formed between the guiding shielding cover 2a and the substrate 1 of the present invention, the heat dissipation efficiency can be effectively increased, and the arrangement of the supporting seats 4 can provide the guiding shielding cover 2a with structural holding force and resistance to insertion force, which will be described in detail one by one below.

[0144] The guiding shielding cover 2a includes a housing 2, a longitudinal partition member 5, a plurality of transverse partition members 6, and a plurality of insertion channels 20. The longitudinal partition member 5 cooperates with the transverse partition members 6 to divide the internal space of the housing 2 into a plurality of insertion channels 20. The front ends of the housing 2, the longitudinal partition member 5, and the transverse partition members 6 are provided with grounding elastic pieces 26, 55, 66, and the bottom ends of the housing 2 and the longitudinal partition member 5 are both provided with holding feet 241, 523 (see Figure 4 , Figure 5)The elevated bumps 242 and 524, and the holding feet 241 and 523 may specifically be, for example, eye of needle (EON) crimping feet. In addition, the guiding shield 2a further includes a plurality of support base fixing parts 21 formed at the bottom end of the housing 2. The housing 2 includes two end walls 23 facing each other in the longitudinal direction L and two side walls 24a and 24b facing each other in the transverse direction W. The two end walls 23 and the two side walls 24a and 24b are connected to form a box-shaped structure. In this embodiment, the housing 2 includes a first half-shell 20a and a second half-shell 20b that are combined with each other. The first half-shell 20a includes a side wall 24a and two end walls 23 with an integral structure, and the second half-shell 20b includes the other side wall 24b. The first half-shell 20a is provided with a first clamping part 27, and the second half-shell 20b is provided with a second clamping part 28. The first half-shell 20a and the second half-shell 20b are combined with each other by clamping the first clamping part 27 and the second clamping part 28. Among them, the first clamping parts 27 are respectively arranged on the side edges of the two end walls 23 opposite to the connecting side wall 24a, and each first clamping part 27 includes a dovetail groove 271, a plurality of clamping convex blocks 272, and a clamping tab 273. Each dovetail groove 271 is recessed from the upper end of the side edge of the end wall 23, the clamping convex blocks 272 protrude from the outer surface of the end wall 23 at intervals up and down, and each clamping tab 273 protrudes from the side edge of the end wall 23 near the lower end. The second clamping parts 28 are respectively arranged on the two side edges of the side wall 24b, and each second clamping part 28 includes a dovetail tab 281, a plurality of clamping holes 282, a plurality of elastic tabs 283, and a clamping hole 284. Among them, each dovetail tab 281 protrudes from the upper end of the side edge of the side wall 24b for fitting into the dovetail groove 271 of the end wall 23. The clamping holes 282 are arranged at intervals up and down on the extending wall 285 extending from the side edge of the side wall 24b for the clamping convex blocks 272 to extend into and be clamped. The elastic tabs 283 extend from the extending wall 285 and are used to abut against the outer surface of the end wall 23 when the clamping convex blocks 272 are clamped in the clamping holes 282. The clamping hole 284 is arranged on the extending piece 286 extending from the lower end of the side edge of the side wall 24b to provide the clamping tab 273 to extend into the clamping hole 284 and be bent and fixed.

[0145] There are bottom air gaps 231 and 243 formed between the bottom end of the housing 2 and the substrate 1. In this embodiment, multiple retaining feet 241 and multiple elevation bumps 242 are configured at the bottom ends of the two side walls 24a and 24b. The multiple retaining feet 241 extend downward and protrude from the bottom ends of the respective side walls 24a and 24b at intervals. One elevation bump 242 is disposed on each side of each retaining foot 241. The retaining foot 241 extends downward beyond the elevation bump 242. The retaining foot 241 is used for insertion and fixation in the holes or conductive holes of the substrate 1 and is elevated above the upper surface of the substrate 1 by the elevation bump 242, so that the aforementioned bottom air gap 243 is formed between the bottom ends of the side walls 24a and 24b and the upper surface of the substrate 1. The bottom ends of the two end walls 23 of the housing 2 in the embodiment are spaced a certain distance from the upper surface of the substrate 1 to form the bottom air gap 231. However, in a variant implementation, retaining feet and elevation bumps can also be additionally provided at the bottom ends of the two end walls 23. The aforementioned grounding spring pieces 26 are respectively disposed at the front ends of the side walls 24a and 24b and the end walls 23 of the housing 2. Each grounding spring piece 26 has multiple elastic fingers 261 on both sides and a buckle 262 connected to the bottom ends of the elastic fingers 261 on the same side. The elastic fingers 261 located on the inner side of each grounding spring piece 26 extend into the insertion channel 20 to contact the pluggable module 3a, and the elastic fingers 261 located on the outer side are used to contact, for example, the frame opening of a panel. The buckle 262 is used for buckling in the corresponding buckle holes 245 and 232 of the side walls 24a and 24b and the end walls 23.

[0146] Refer to Figure 1 , Figures 5 to 7 , Figure 11 , Figure 12 , the intermediate member 5 extends along the longitudinal direction L and is assembled on the two end walls 23. The intermediate member 5 includes two spaced longitudinal partitions 52 and an air flow channel 51 formed between the two longitudinal partitions 52. A front end opening 50a communicating with the air flow channel 51 is defined between the front ends of the two longitudinal partitions 52 (see Figure 5 ), and a bottom end opening 50b communicating with the air flow channel 51 is defined between the bottom ends of the two longitudinal partitions 52 (see Figure 5)。In addition, the intermediate partition member 5 further includes a front end plate 53 extending along the longitudinal direction L and disposed between the front ends of the two longitudinal partition plates 52, at least one bottom support piece 54, and a plurality of assembly pieces 56, 561. The front end plate 53 can be bent and extended from the front edge of one of the longitudinal partition plates 52 towards the other longitudinal partition plate 52 and is formed with a plurality of spaced convex pieces 532 for snap-fitting (interfering) into the notches 533 provided at the front edge of the other longitudinal partition plate 52. The front end plate 53 is provided with a plurality of air flow holes 531 communicating with the air flow channels 51. The front end plate 53 can cover most of the front end opening 50a of the air flow channels 51, but communicates with the air flow channels 51 through the plurality of air flow through holes 531. The bottom support piece 54 is bent and extended from the bottom edge of one of the longitudinal partition plates 52 towards the other longitudinal partition plate 52 and is snap-fitted to the other longitudinal partition plate 52. The bottom support piece 54 is only partially located at the bottom end opening 50b of the air flow channel 51. In this embodiment, the bottom support piece 54 has a convex piece 541 for snap-fitting (interfering) into the other longitudinal partition plate 52, and the other longitudinal partition plate 52 is provided with a jack 542 for the convex piece 541 to be inserted and interfered. Through the arrangement of the front end plate 53 and the bottom support piece 54, the distance between the two longitudinal partition plates 52 can be maintained to form the air flow channels 51. The assembly pieces 56, 561 are formed on the two side edges of the two longitudinal partition plates 52. The assembly piece 56 is used to pass through the hole 230 provided on the end wall 23 (see Figure 3 ) and then be bent and fixed, thereby being snap-fitted to the end wall 23 of the housing 2. Some of the assembly pieces 561, such as the assembly pieces 561 located at the upper and lower ends of the two side edges of the two longitudinal partition plates 52, can just be snapped into the holes 230 of the end wall 23 without being bent, providing a positioning function.

[0147] Among the holding feet 523 and the raised bumps 524 provided at the bottom end of the intermediate partition member 5, the holding feet 523 extend downward and protrude from the bottom ends of the respective longitudinal partition plates 52 at intervals. One raised bump 524 is disposed on each side of each holding foot 523. The holding feet 523 extend downward beyond the raised bumps 524. The holding feet 523 are used for being inserted and fixed into the holes or conductive holes of the substrate 1, and are raised above the upper surface of the substrate 1 through the raised bumps 524, so as to form a bottom end air flow gap 525 between the bottom end of the intermediate partition member 5 and the upper surface of the substrate 1 (see Figure 12 ). The aforementioned grounding elastic pieces 55 are respectively disposed at the front ends of each longitudinal partition plate 52. Each grounding elastic piece 55 has a plurality of elastic fingers 551 on one side and located outside the longitudinal partition plate 52, and a hook 552 connected to the bottom ends of the elastic fingers 551. The elastic fingers 551 are used for extending into the insertion channel 20, and the hook 552 is used for buckling on the corresponding buckle holes 57 of the longitudinal partition plate 52 (see Figure 6 ).

[0148] Refer to Figure 1 、 Figure 8A 、 Figures 8B to 12, each transverse partition member 6 includes two spaced-apart diaphragms 62 and an air flow channel 61 formed between the two diaphragms 62. The transverse partition members 6 are a plurality of members spaced apart from each other along the longitudinal direction L and are respectively assembled on both sides of the longitudinal partition member 5 and between the two side walls 24a, 24b of the outer shell 2 in the transverse direction W, so as to divide the inner space of the outer shell 2 into a plurality of insertion channels 20. The bottom ends of the two diaphragms 62 of each transverse partition member 6 are spaced a certain distance from the upper surface of the substrate 1, so as to form a bottom air flow gap 64 between the bottom end of the transverse partition member 6 and the substrate 1 (see Figure 12 ). In a variant embodiment, retaining feet and heightening bumps can also be additionally provided at the bottom ends of the two diaphragms 62 of each transverse partition member 6. The bottom end of each insertion channel 20 covers a socket 3 located on the substrate 1. Each insertion channel 20 extends along an insertion direction I in the height direction H and is upright relative to the substrate 1 and has a front socket 201 away from the substrate 1 and the socket 3 and a bottom opening 202 adjacent to the substrate 1. In this embodiment, each transverse partition member 6 further includes a plurality of side support pieces 63a, 63b between the two diaphragms 62 and a plurality of assembly pieces 65. The front end between the two diaphragms 62 of each transverse partition member 6 defines a front opening 60a communicating with the air flow channel 61, and the bottom end defines a bottom opening 60b communicating with the air flow channel 61. The plurality of side support pieces 63a, 63b can be bent and extended from the two side edges of one of the diaphragms 62 towards the other diaphragm 62 for maintaining the distance between the two diaphragms 62 (i.e., maintaining the air flow channel 61). In this embodiment, the side support pieces 63a between the same side edges of the two diaphragms 62 are of an integral structure and are bent and connected to the two diaphragms 62, while the side support pieces 63b on the other side edge of the two diaphragms 62 are integrally bent and extended from one of the diaphragms 62 and abutted against the other diaphragm 62. The assembly pieces 65 are formed on the two side edges of the two diaphragms 62. The assembly pieces 65 on each diaphragm 62 are used for passing through the holes 510, 240 provided in the longitudinal partition 52 of the longitudinal partition member 5 and the side walls 24a, 24b of the outer shell 2 (see Figure 10 , Figure 11 ) and then being bent and fixed, and making the bottom end of the diaphragm 62 spaced above the substrate 1 to form the bottom air flow gap 64. In this embodiment, with reference to Figure 10, to ensure that the transverse partition member 6 can be stably arranged between the longitudinal partition member 5 and the side walls 24a, 24b of the outer shell 2, between the inner walls of the two transverse partitions 62 of each transverse partition member 6, there are inner support pieces 521, 244. In this embodiment, the two inner support pieces 521, 244 are respectively formed on each longitudinal partition 52 and the side walls 24a, 24b of the outer shell 2. The two inner support pieces 521, 244 can be specifically formed by locally stamping and obliquely bending the longitudinal partition 52 and the side walls 24a, 24b of the outer shell 2. The two inner support pieces 521, 244 face each other and are relatively positioned corresponding to both sides of the transverse partition member 6 and extend into the space between the two transverse partitions 62, thereby supporting between the two transverse partition members 6. In addition, in this embodiment, each transverse partition 62 of each transverse partition member 6 has a bent piece 621 located at the front end and bent downward into the air flow channel 61. The bent pieces 621 at the front ends of the two transverse partitions 62 of each transverse partition member 6 are staggered from each other in the transverse direction and are partially located at the front end opening 60a of the air flow channel 61. By forming the two bent pieces 621, it can also help maintain the air flow channel 61 between the transverse partitions 62, and can also prevent the pluggable module 3a from being misinserted into the air flow channel 61. The aforementioned grounding elastic pieces 66 are respectively arranged at the front ends of each transverse partition 62. Each grounding elastic piece 66 has a plurality of elastic fingers 661 on one side and located outside the transverse partition 62, and a hook 662 connected to the bottom end of the elastic fingers 661. The elastic fingers 661 are used to extend into the insertion channel 20, and the hook 662 is used to latch onto the corresponding latching hole 67 on the transverse partition 62.

Together with the bottom air flow gaps 525, 64 between the bottom ends of the inter-septum member 5 and the inter-diaphragm member 6 and the substrate 1, the outside cold air can enter between the inter-septum member 5 and the inter-diaphragm member 6 through the front end openings 50a, 60a, exchange heat with the hot air inside the guiding shielding cover 2a, and then be dissipated downward through the bottom end openings 50b, 60b, the bottom air flow gaps 525, 64 of the inter-septum member 5 and the inter-diaphragm member 6, and the air circulation holes 11 of the substrate 1. And part of the hot air can also be dissipated through the bottom air flow gap 243 of the outer shell 2, thereby improving the heat dissipation effect of the entire guiding shielding cover 2a.

[0152] Refer to Figure 9 , Figures 11 to 14 , the support seat fixing part 21 is formed at the lower ends of the two end walls 23 of the outer shell 2. Each support seat fixing part 21 includes a first engaging part 21a and a first support part 21b; the first engaging part 21a includes a plurality of pin holes 211 penetrating through the support seat fixing part 21. Each support seat fixing part 21 includes a raised part 212 bulging outward from the outer surface of the outer shell 2 and a recessed part 213 recessed from the inner surface of the outer shell 2. In this embodiment, the support seat fixing part 21 is formed by stamping a local area of the end wall 23 to bulge relative to the outer surface of the end wall 23 and the inner surface of the end wall 23 to be recessed to form the aforementioned raised part 212 and recessed part 213. The pin holes 211 are located in the stamped area and penetrate through the raised part 212 and the recessed part 213. The first support part 21b includes the bottom edge 25 at the lower end of the support seat fixing part 21. Each support seat fixing part 21 further includes a bottom notch 22. An upwardly recessed bottom notch 22 is formed between the bottom edge 25 of each support seat fixing part 21 and the bottom edge of the end wall 23 of the outer shell 2.

[0153] Each support base 4 is respectively assembled to each support base fixing portion 21. Each support base 4 includes a second engaging portion 4a and a second supporting portion 4b. The second engaging portion 4a is assembled and engaged with the first engaging portion 21a for fixing, and the second supporting portion 4b supports the first supporting portion 21b in the downward direction of the housing 2; the second supporting portion 4b of each support base 4 includes a support table portion 41, and the second engaging portion 4a includes a plurality of fixing pins 42; the support table portion 41 extends inward relative to the housing 2 into the bottom notch 22 and supports on the bottom edge 25 of the support base fixing portion 21, and the fixing pins 42 are engaged with the pin holes 211 of the support base fixing portion 21. Each support base 4 of this embodiment further includes a substantially concave-shaped body 40, a fastener fitting hole 45 penetrating the body 40 in the height direction H, and two standing brackets 43 protruding downward from each other at the bottom end of the body 40 and located on both sides of the fastener fitting hole 45. The fastener fitting hole 45 is located in the concave portion of the body 40 in the shape of a concave and can specifically be a threaded hole. The body 40 of the support base 4 has an inner surface portion 40a facing the inside of the housing 2 (facing the direction of the end wall 23). Three fixing pins 42 are constructed on the upper part of the inner surface portion 40a of the body 40, and a support table portion 41 is constructed on the lower part. The support table portion 41 protrudes from the body 40 in the direction facing the inside of the housing 2 to form a convex platform structure, and the support table portion 41 has a support top edge 411 and an inner surface 412 facing the inside of the housing 2. The fastener fitting hole 45 provides a fastener 46 (see Figure 2 ) to pass upward through the through holes provided in the substrate 1 from the back surface of the substrate 1 and be locked to the fastener fitting hole 45, locking the support base 4 to the substrate 1, and enabling the bottom ends of the two standing brackets 43 to support on the upper surface of the substrate 1. And when the support base 4 is assembled to the end wall 23, the upper half of its body 40 abuts against the surface of the raised portion 212 of the support base fixing portion 21. The fixing pins 42 pass through the body 40 and the pin holes 211, and a mushroom-shaped head is formed at one end of the fixing pins 42 located in the recessed portion 213 and riveted to the recessed portion 213. Thus, the support base 4 is combined and fixed to the support base fixing portion 21, and the standing brackets 43 support on the surface of the substrate 1. The support top edge 411 is located below the bottom edge 25 to provide the bottom edge 25 to abut against. The support top edge 411 of the support table portion 41 of each support base 4 supports the bottom edge 25 at the lower end of the support base fixing portion 21 in the downward direction to achieve the supporting effect. Therefore, in addition to the support table portion 41 of the support base 4 supporting on the bottom edge 25 of the support base fixing portion 21, the support base 4 is also riveted to the support base fixing portion 21 through the fixing pins 42.

[0154] In this embodiment, as Figure 9As shown, the support bases 4 are arranged at the positions of the two end walls 23 such that the two support bases 4 adjacent to each end wall 23 are spaced from each other by at least the width of one support base 4, and the support bases 4 on one end wall 23 are staggered from the support bases 4 on the other end wall 23 by at least the width of one support base 4 in the transverse direction W. With such a configuration, by virtue of the differences in the positions of the support bases 4 at the two end walls 23 and the sufficient spacing distance, the housing 2 can be more stably supported on the substrate 1. Additionally, in this embodiment, when the support base 4 is fixedly coupled to the support base fixing portion 21, the mushroom-shaped head 421 of the fixing pin 42 located in the recessed portion 213 does not protrude beyond the inner surface of the end wall 23, and the inner surface 412 of the support platform portion 41 also does not protrude beyond the inner surface of the end wall 23, thereby preventing interference with the insertion of the pluggable module into the insertion channel 20.

[0155] The material of the support base 4 can be a non-conductive plastic material, or a conductive metal material or a plastic-coated metal material to give it a conductive effect. At this time, by contacting the grounding pad provided on the substrate 1 through the standing bracket 43, the grounding and electromagnetic shielding effects of the guiding shielding cover 2a can also be enhanced.

[0156] Therefore, from the foregoing description, it can be seen that through the arrangement of the support base fixing portion 21 and the support base 4 of the present invention, the holding force and resistance to the insertion force of the housing 2 in terms of structure can be enhanced, and the support base 4 does not affect the insertion of the pluggable module into the insertion channel 20. Thus, the object of the present invention can indeed be achieved.

[0157] In addition, through the formation of the air flow holes 11 in the substrate 1 and their connection to the insertion channel 20, the heat dissipation effect of the housing 2 is effectively improved. Further, by using the air flow channels 51, 61 of the longitudinal partition member 5 and the transverse partition member 6, and the front openings 50a, 60a and bottom openings 50b, 60b are formed in the air flow channels 51, 61, and the air flow holes 531 and bottom air flow gaps 525, 64 of the front end plate 53 of the longitudinal partition member 5 are provided, the air flow is provided to flow through the longitudinal partition member 5 and the transverse partition member 6, and the longitudinal partition member 5 and the transverse partition member 6 are also provided with heat dissipation effects.
