Description

Technical Field

[0001] This invention relates to the field of shielding for high-frequency connectors, and more particularly to a connector housing and a connector. Background Technology

[0002] With the continuous development of communication technology, the use of high-speed inter-board connectors is becoming increasingly widespread. Chinese invention patent CN113612081B discloses a sub-connector and its chip, taking a bent male connector as an example, including a connector housing and multiple chips. Each chip includes a plate-shaped insulating body and differential signal pins fixed within the insulating body. One end of each differential signal pin extends from one edge of the insulating body, having a fisheye end for connection with the printed circuit board, and the other end extends from the other edge of the insulating body, having a mating end for insertion with an adapter connector. Shielding plates are installed on both sides of the insulating body. The shielding plates extend outwards at positions corresponding to the mating ends, allowing the mating ends to extend between the extended sections of the two shielding plates, thus creating a mating space for the mating ends of the adapter connector to insert and engage. Furthermore, within this mating space, a shielding plate connecting conductor, i.e., a support plate, is provided between adjacent differential pairs. The support plate and the upper and lower shielding plates form independent mating cavities for the mating ends of the adapter connector to extend into, providing shielding for adjacent differential pairs at the mating position. Multiple chips are installed inside the connector housing, which has a mating end plate facing the side of the adapter connector. The mating end of the insulating body is located inside the mating end plate. The mating end plate is a grid plate, with each grid hole corresponding to the mating end. The grid holes are used for the mating end of the adapter connector to pass through and extend into the mating cavity.

[0003] As connectors increasingly strive for miniaturization and high density, the shell walls of connector housings are often thinner. This results in weak structural strength of the grid-like plug end plate. In actual use, it has been found that the plate is prone to deformation when subjected to impact during plugging, failing to provide reliable guidance and protection for the plug end during plugging. Summary of the Invention

[0004] The purpose of this invention is to provide a connector housing to address the problem that existing connector housings lack structural strength and are prone to deformation under impact during insertion, thus failing to provide reliable guidance and protection. Furthermore, this invention also aims to provide a connector that addresses the problem of existing connector housings lacking structural strength, easily deforming, and causing damage to the insertion end or preventing successful insertion.

[0005] The connector housing of the present invention includes a plug-in end plate and a plug-in enclosure wall located at the edge of the plug-in end plate. The plug-in end plate and the plug-in enclosure wall form an installation cavity for each chip to be inserted. The plug-in end plate is a grid plate, and each grid hole corresponds to each plug-in end of the chip so that the plug-in end of the adapter connector can pass through to achieve plugging. At least some of the grid holes are provided with reinforcing structures protruding in the plugging direction on the grid strips to improve the structural strength of the grid strips.

[0006] Furthermore, the reinforcing structure protrudes to one side of the mounting cavity, and there is a gap between the end of the longitudinal reinforcing structure on the longitudinal grid bar and the transverse reinforcing structure on the transverse grid bar to form a positioning insertion interval for the edge of the overhanging section of the shielding sheet extending laterally from the wafer to be inserted.

[0007] Furthermore, the longitudinally reinforcing structure has longitudinally extending positioning insertion slots for the insertion of the end of the support plate within the wafer insertion space.

[0008] Furthermore, the longitudinal reinforcement structure includes a reinforcing boss and longitudinal reinforcing protrusions on the platform of the reinforcing boss. The longitudinal reinforcing protrusions are arranged in pairs and are laterally spaced, and the positioning insertion groove is formed between the two longitudinal reinforcing protrusions.

[0009] Furthermore, the positioning insertion interval is a flared interval.

[0010] Furthermore, the transverse reinforcement structure consists of transverse reinforcing ribs, which are ridge-shaped to allow the edge of the overhanging section of the shielding sheet to be inserted into the positioning insert interval.

[0011] Furthermore, the end of the longitudinal reinforcement structure near the transverse reinforcement structure has a guiding bevel to cooperate with the ridge-shaped transverse reinforcement rib to form a guiding flare.

[0012] Furthermore, the positioning insertion slot is a flared slot to allow the end of the support plate to be inserted.

[0013] This invention improves upon existing connector housings by providing reinforcing structures that protrude in the insertion direction on the grid strips that form the grid holes. This increases the structural strength of the grid strips without affecting the insertion, thereby improving the overall structural strength of the insertion end plate, enhancing its impact resistance, and making it less prone to deformation due to impact forces during insertion. This also improves reliable guiding and protection of the insertion end on its rear side.

[0014] The connector of the present invention includes a connector housing and a plurality of wafers installed in the connector housing. The connector housing includes a plug end plate and a plug enclosure wall located at the edge of the plug end plate. The plug end plate and the plug enclosure wall form a mounting cavity for each wafer to be inserted. The plug end plate is a grid plate, and each grid hole corresponds to each plug end of the wafer so that the plug end of the adapter connector can pass through to achieve plugging. At least some of the grid holes are provided with reinforcing structures protruding in the plugging direction on the grid strips to improve the structural strength of the grid strips.

[0015] Furthermore, the reinforcing structure protrudes to one side of the mounting cavity, and there is a gap between the end of the longitudinal reinforcing structure on the longitudinal grid bar and the transverse reinforcing structure on the transverse grid bar to form a positioning insertion interval for the edge of the overhanging section of the shielding sheet extending laterally from the wafer to be inserted.

[0016] Furthermore, the longitudinally reinforcing structure has longitudinally extending positioning insertion slots for the insertion of the end of the support plate within the wafer insertion space.

[0017] Furthermore, the longitudinal reinforcement structure includes a reinforcing boss and longitudinal reinforcing protrusions on the platform of the reinforcing boss. The longitudinal reinforcing protrusions are arranged in pairs and are laterally spaced, and the positioning insertion groove is formed between the two longitudinal reinforcing protrusions.

[0018] Furthermore, the positioning insertion interval is a flared interval.

[0019] Furthermore, the transverse reinforcement structure consists of transverse reinforcing ribs, which are ridge-shaped to allow the edge of the overhanging section of the shielding sheet to be inserted into the positioning insert interval.

[0020] Furthermore, the end of the longitudinal reinforcement structure near the transverse reinforcement structure has a guiding bevel to cooperate with the ridge-shaped transverse reinforcement rib to form a guiding flare.

[0021] Furthermore, the positioning insertion slot is a flared slot to allow the end of the support plate to be inserted.

[0022] Furthermore, the front end of the support plate within the interlocking space of the wafer has a guide end for insertion into the positioning insertion slot.

[0023] This invention improves existing connectors, especially their connector housings, by providing reinforcing structures that protrude in the insertion direction on the grid strips that form the grid holes. This improves the structural strength of the grid strips without affecting the insertion, thereby improving the structural strength of the entire insertion end plate, enhancing impact resistance, and making it less prone to deformation due to impact forces during insertion. It also improves reliable guiding and protection of the rear insertion end. Attached Figure Description

[0026] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0027] The connector of the present invention improves the structural strength of its grid-shaped plug end plate by modifying the structure of the connector housing, thereby improving its impact resistance. It is not easily deformed by impact force during the plugging process, which can improve the reliable guiding effect and the protection of the plug end on the rear side.

[0028] Specific embodiments of the connector of the present invention are as follows: Figure 1-24 As shown. The connector includes an assembly housing and connector chips 1. Multiple connector chips 1 are stacked in the thickness direction and then fixedly assembled by the assembly housing to form an integral structure for mating with the adapter connector and connecting to the printed circuit board. For ease of accurate explanation, the thickness direction of the connector chip 1 is defined as the vertical direction, and the side of the connector chip 1 facing the adapter connector is defined as the front side.

[0029] like Figure 1-5As shown, the connector chip 1 includes a plate-shaped insulating body 12 and shielding plates 13 mounted on both sides of the insulating body 12. A pair of differential pins are fixed inside the insulating body 12, with both ends extending from the edges of the insulating body 12. One end is a differential pin fisheye end 10 for connecting to the printed circuit board, and the other end is a plug-in end for plugging into the differential pins of the adapter connector. Shielding plate mounting slots 120 are provided on both sides of the insulating body 12. The shielding plate 13 is mounted within the mounting slots 120. A mounting protrusion 121 is provided on the insulating body 12 within the mounting slots 120, and a mounting hole corresponding to the mounting protrusion 121 is provided on the shielding plate 13. When the shielding plate 13 is mounted into the mounting slots 120, the mounting protrusion 121 is inserted into the mounting hole. The interference fit between the two achieves the fixed mounting of the shielding plate 13 on the side of the insulating body 12.

[0030] The assembly housing includes a snap-fit ​​fastener, a positioning plate 3, and a connector housing. Multiple connector chips 1 are stacked together and secured together by the snap-fit ​​fastener to prevent them from separating. The positioning plate 3 is fastened to the sides of all insulating bodies 12 from the differential pin fisheye end 10. The assembly formed by the multiple connector chips 1, the snap-fit ​​fastener, and the positioning plate 3 is inserted into the connector housing. The assembly method between the multiple connector chips 1, the snap-fit ​​fastener, and the positioning plate 3 is the same as in the prior art and will not be described further here.

[0031] The structure of the connector housing is as follows Figure 20-24 As shown, a shell-like structure with an opening on one side includes four insertion walls and insertion end plates perpendicular to the four insertion walls. Its inner cavity is a wafer mounting cavity 40. Two opposing insertion walls among the four insertion walls have wafer insertion slots 400, and the edges of each wafer slide into the wafer mounting cavity 400 along the wafer insertion slots 400. The insertion end plates are grid end plates 6, with grid holes 60 corresponding to the insertion ends of the differential pins of the wafer, allowing the insertion of adapter connectors to achieve connection and conduction between the two connectors.

[0032] like Figure 3-5As shown, the shielding plate 13 of the connector chip 1 has a shielding plate overhanging section 131 protruding from the edge of the insulating body 12 on the side where the plug end is located. The plug end of the differential pin extends into the mating space formed between the two shielding plate overhanging sections 131 on the upper and lower sides of the insulating body 12. In this mating space, support plates 5 are provided on both sides of each pair of differential pin plug ends 101 to achieve shielding of adjacent pairs of differential pins at the mating position. The two adjacent support plates 5 and the shielding plates 13 on the upper and lower sides together form a rectangular cavity. This rectangular cavity is a plugging cavity for inserting a differential pair of the adapter connector and the rectangular shielding cylinder surrounding it. The differential pairs of the two connectors are plugged into each other, and the shielding cylinder of the adapter connector makes conductive contact with the cavity wall of the plugging cavity to achieve grounding. The upper and lower shielding plates 13 are provided with shielding plate fisheye ends 11 on one side edge corresponding to the fisheye ends 10 of the differential pins. The shielding plate fisheye ends 11 are located on the left and right sides of the fisheye ends 10 of two adjacent pairs of differential pins, and shield the two adjacent pairs of differential pins at the position where they are connected to the printed circuit board. The specific structure is similar to that of the prior art.

[0033] The support plate 5 is fixedly assembled at a specific position in the insertion space by inserting and fixing the upper and lower edges of the support plate 5 with the two shielding plates 13 on the upper and lower sides in the vertical direction. Thus, when the shielding plates 13 on the upper and lower sides are fastened onto the insulating body 12, the support plate 5 is simultaneously installed between the two shielding plates 13.

[0034] Specifically, such as Figure 6-14 The upper and lower shielding plates 13 are provided with shielding plate 13 insertion structures at positions corresponding to the support plate 5. Each shielding plate 13 insertion structure includes a limiting slot spaced apart front to back, with the limiting slot opening towards the other shielding plate 13. The limiting slot allows the support plate 5 to be inserted vertically and clamped from both sides at its front and rear ends, thus limiting the support plate 5 in the lateral direction. In the embodiment shown, the shielding plate 13 has a pair of latches 132 punched out, extending towards the support plate 5. The pair of latches 132 cooperate to form the limiting slot. In other embodiments, the shielding plate 13 may also have a pair of rectangular protrusions stamped on it, with the recess between the two protrusions forming the limiting slot. Alternatively, in other embodiments, a U-shaped clip may be welded onto the shielding plate 13, with the space inside the U-shaped clip forming the limiting slot.

[0035] In the embodiment shown in the figure, there are two limiting slots, one in front and one behind, for insertion into the vicinity of the front and rear ends of the support plate 5. Of course, the present invention is not limited to this embodiment. In other embodiments, there may be one limiting slot corresponding to the middle position of the support plate 5, or there may be multiple limiting slots, arranged at intervals along the front and rear direction of the support plate 5.

[0036] Furthermore, the shielding plate 13 is provided with an insertion protrusion extending toward the support plate 5. The edge of the support plate 5 is provided with an insertion slot corresponding to the insertion protrusion. The two shielding plates 13 are interlocked and the insertion protrusion is inserted into the insertion slot, thereby achieving the insertion and fixation of the two. Specifically, the insertion protrusion is a folded protrusion 133 formed by punching on the shielding plate 13. The folded protrusion 133 on the shielding plate 13 is folded toward the other shielding plate 13. The folded protrusion 133 extends along the front-back direction and protrudes from the surface of the shielding plate 13. In order to improve the insertion reliability between the insertion protrusion and the insertion slot, this embodiment provides a more optimized design, that is, the insertion protrusion is provided with a forced fitting protrusion 134, which is used to forcefully fit with the inner wall of the insertion slot.

[0037] The structure of support plate 5 is as follows Figure 10-12 As shown, the support plate 5 is a sandwich structure, comprising two single-sided plates 50. The two layers of the sandwich support plate 5 are arranged side-by-side in the left-right direction and extend forward and backward. The central sandwich space 51 between the two layers forms an insertion slot for the folding protrusion 133 to be inserted. During manufacturing, the support plate 5 is made by punching and stamping a single sheet, and then folding the resulting elongated semi-finished product in half from the middle, thus forming the sandwich structure support plate 5. This manufacturing method has a lower cost, and the central sandwich space 51 has a larger length in the forward and backward direction, which can accommodate positional deviations of the insertion protrusion in the forward and backward direction.

[0038] As shown in the figure, the front end of the support plate 5 is a folded section. The rear side of the folded rib at the front end forms inclined sections that are far apart from each other, that is, the front end of the support plate 5 is V-shaped. The rear end of the inclined section forms a straight section that extends backward. The insert protrusion is inserted into the middle interlayer space 51 between the two straight sections. The inner edges of the upper and lower edges of the two straight sections are respectively provided with chamfers, so that the insert slot formed between them is a flared slot, so that the folded protrusion 133 can be inserted.

[0039] The limiting slots correspond to the front and rear ends of the straight sections. To prevent the two straight sections from deforming and moving closer together under clamping force due to material properties, thus ensuring a secure clamping constraint between the limiting slots and the support plate 5, the support plate 5 has interlayer support structures at both its front and rear ends. The limiting slots are positioned close to these interlayer support structures. These structures provide support between the two layers of the support plate 5, preventing them from moving closer together and ensuring the reliability of the clamping constraint. Figure 11In the illustrated embodiment, the interlayer central support structure includes support protrusions 53 stamped on both sides of the support plate 5. The two support protrusions 53 protrude towards each other and their top surfaces abut against each other, supporting the two side plates. In other embodiments, a support protrusion 53 can be provided on one of the two side plates of the support plate 5, increasing its protrusion height so that it directly abuts against the surface of the other side plate, thus achieving the same supporting function. These embodiments all involve forming the interlayer central support structure without adding any components. In some other embodiments, a support pad can be sandwiched between the two layers of the support plate 5 to form the interlayer central support structure. Of course, an implementation without a interlayer central support structure is also a feasible approach.

[0040] The rear ends of the two straight sections narrow in the width direction (vertical direction) and come close to each other to form an insertion tail section 55. The insertion tail section 55 is used to insert into the support plate insertion groove 122 opened at the edge of the insulating body 12 to realize the fixed installation between the rear end of the support plate 5 and the insulating body 12. Figure 8 The structure of the support plate insertion slot 122 on the insulating main board is shown. The edge of the insulating body 12 is provided with a support plate insertion slot 122 that penetrates the insulating body 12 in the thickness direction for the rear end of the support plate 5 to be inserted. It can be seen that the support plate insertion slot 122 is not a normal rectangular slot with the opening facing forward. Instead, a pair of forced mounting protrusions 134 are provided at the front end near the opening and at the rear end near the bottom of the slot, respectively. After the insertion tail section 55 is inserted into the support plate insertion slot 122, it is interference-clamped with the forced mounting protrusions 134, thereby ensuring the insertion reliability between the support plate 5 and the insulating body 12. Of course, the implementation without the forced mounting protrusions 134 is also a feasible method. In order to facilitate the insertion of the insertion tail section 55 into the support plate insertion slot 122, the front end of each pair of forced mounting protrusions 134 is provided with a guide surface 125. The guide surfaces 125 on the two forced mounting protrusions 134 together form a flared structure.

[0041] The support plate 5 is inserted into the support plate insertion slot 122 via an insertion tail section 55 on one vertical surface, which can ensure positional accuracy in the left and right directions. However, whether the support plate 5 can extend straight back and forth cannot be guaranteed at the rear end position of the support plate 5. Therefore, the groove edge of the support plate insertion slot 122 on at least one side of the insulating body 12 is recessed to form a surface positioning groove 123. The rear end of the support plate 5 is folded to form a folded positioning wing plate 56 extending along the surface of the insulating body 12. After the insertion tail section 55 is inserted into the support plate insertion slot 122, the folded positioning wing plate 56 is inserted into the surface positioning groove 123 from front to back, and the plate surface of the folded positioning wing plate 56 is in contact with the bottom of the surface positioning groove 123 to prevent the support plate 5 from deviating in the thickness direction of the insulating body 12. As shown in the figure, both layers of the support plate 5 of the sandwich structure are equipped with folding positioning wing plates 56 on their insert tail sections 55. The upper and lower edges of the insert tail section 55 are folded to form the folding positioning wing plates 56. This effectively ensures high positioning accuracy and retention between the insert tail section 55 and the support plate insert groove 122, thereby improving the installation accuracy of the support plate 5. Of course, the number of folding positioning wing plates 56 and the arrangement of the surface positioning grooves 123 can vary in different embodiments. For example, if one side of the support plate 5 of the sandwich structure has a folding positioning wing plate 56 on its insertion tail section 55, while the other side does not have a folding positioning wing plate 56, and there is only one folding positioning wing plate 56, then the insulating body 12 only has surface positioning grooves 123 on one side of both the upper and lower sides. If there are two folding positioning plates 3 and they are opposite each other, then the upper and lower sides of the insulating body 12 will both have surface positioning grooves 123 at positions corresponding to the folding positioning wing plate 56. Alternatively, the support plate 5 of the sandwich structure may have a folding positioning wing plate 56 on each side of its insertion tail section 55, with the two folding positioning wing plates 56 on the same plane or one higher than the other.

[0042] The support plate 5 is provided with contact springs 52 protruding to the left and right sides. The contact springs 52 are used to elastically abut against the side of the shielding cylinder of the adapter connector to achieve grounding and conduction. The contact springs 52 on the left and right sides are respectively set on the two side plates of the support plate 5 of the sandwich structure and are formed by punching and stamping. The contact springs 52 are located between the front and rear limiting slots, and also between the middle support structures of the front and rear sandwich structures.

[0043] The structure of the connector housing is as follows Figure 20-24 As shown, the structure formed by multiple connector chips 1, mounting fasteners, and positioning plates 3 is inserted into the connector housing as follows. Figure 1As shown in Figures 15-19, the connector housing is integrally injection molded and includes four insertion enclosures (top, bottom, left, and right) and insertion end plates connected to the front ends of the four insertion enclosures. The insertion end plates are grid end plates 6, with grid holes 60 at positions corresponding to each insertion cavity to prevent the insertion of the adapter connector. The rear ends of the left and right insertion enclosures protrude rearward beyond the top and bottom insertion enclosures, and each of the left and right insertion enclosures has a chip insertion slot 400 for each chip to slide into the connector housing. The front ends of the left and right insertion enclosures protrude and extend with guide keys 41 to mate with guide slots on the adapter connector housing, achieving accurate mating of the two connectors.

[0044] The grid hole 60 is a rectangular hole, and the grid bars surrounding the grid hole 60 include horizontal grid bars 61 extending left and right and vertical grid bars 62 extending up and down. The horizontal grid bars 61 have a horizontally extending reinforcing rib 63 at the rear center, which is a horizontal reinforcement structure to improve the structural strength of the horizontal grid bars. The vertical grid bars 62 have vertically extending reinforcing bosses 64 at the rear, and the ends of the reinforcing bosses 64 and the horizontal reinforcing ribs 63 are spaced to form a positioning insertion interval 651. Figure 19 As shown, the positioning insertion interval allows the front edge of the overhanging section of the shielding sheet to be inserted. This ensures that after the wafers are installed in the connector housing, the front ends of the shielding sheets of each wafer can extend into the positioning insertion interval 651, thereby achieving positioning and assembly of the shielding sheet and the connector end plate. By limiting and reinforcing the shielding sheet 13, large deformation and displacement of the shielding sheet 13 after installation are prevented.

[0045] The reinforcing boss 64 has longitudinal reinforcing protrusions 65 on its platform. The reinforcing boss and the longitudinal reinforcing protrusions together constitute a longitudinal reinforcing structure to improve the structural strength of the longitudinal grid strips. The longitudinal reinforcing protrusions 65 are arranged in pairs and laterally spaced, and a longitudinally extending positioning insertion groove 66 is formed between two longitudinal reinforcing protrusions 65. The positioning insertion groove 66 is for the end of the support plate 5 to be inserted. In this way, after the chip is installed into the connector housing, the front end of each support plate 5 can extend into the positioning insertion groove 66, thereby realizing the positioning and assembly of the support plate 5 and the plug-in end plate. In a preferred embodiment, such as Figure 18 , 24 As shown, to facilitate the installation of the chip into the connector housing, the opposite sides of the longitudinal reinforcing protrusion 65 are respectively provided with opposing inclined surfaces to form a flared opening, that is, the positioning insertion groove 66 is a flared groove. The front end of the support plate 5 is flattened to form a guide end 54 extending vertically. The guide end 54 can be inserted into the positioning groove 62 of the support plate to limit and position the support plate 5, and to enhance the positional accuracy and strength of the support plate 5.

[0046] like Figure 21In the illustrated embodiment, in the longitudinal direction, every two rows of grid holes form a group. The transverse reinforcing ribs 63 on the transverse grid strip 61 shared by adjacent rows of grid holes in the same group extend continuously in the transverse direction. The longitudinal reinforcing protrusions on the reinforcing bosses 64 on both sides of the transverse reinforcing rib 63 are all located at the ends of the reinforcing bosses and are all close to the transverse reinforcing rib 63. The transverse reinforcing ribs on another transverse reinforcing strip that is longitudinally adjacent to the transverse reinforcing strip are intermittently arranged.

[0047] To facilitate the insertion of the front edge of the overhanging section of the shielding sheet into the positioning insertion interval 651, the positioning insertion interval is a flared interval. Specifically, the transverse reinforcing rib 63 is ridge-shaped, and the end face of the reinforcing boss 64 and the longitudinal reinforcing protrusion 65 on it, near the transverse reinforcing rib 63, is a guide slope 650 facing away from the transverse reinforcing rib 63. Thus, the flared positioning insertion interval 651 is formed by the guide slope 650 and the inclined side of the transverse reinforcing rib.

[0048] Thus, the structural strength of the grid strips is improved through the transverse and longitudinal reinforcement structures, thereby enhancing the overall structural strength of the grid end plate and its impact resistance. Furthermore, the transverse and longitudinal reinforcement structures have a positioning insertion relationship with the shielding plate and support plate of the chip, improving the positional accuracy and assembly strength of the chip when it is installed in the connector housing. Moreover, after the support plate and shielding plate are inserted into the corresponding positioning insertion slots and positioning insertion intervals, the front end of the chip supports the insertion end plate. When the insertion end plate of the connector housing is subjected to external extrusion force, the front end of the chip can also abut against the insertion end plate from the inside to provide support force, further improving the impact deformation resistance of the connector housing.

[0049] In the above embodiments, the shielding sheet 13 insertion structure includes a limiting slot formed by a pair of latches 132 and an insertion protrusion formed by a folding protrusion 133. In other embodiments, the shielding sheet 13 insertion structure may only include the limiting slot. In this case, the support plate 5 may be a single-layer structure, and the contact springs 52 on the left and right sides can be formed by punching and stamping on the single-layer support plate. The front end of the single-layer support plate constitutes the guide end 54, and the rear end serves as the insertion tail section 55. Alternatively, in another embodiment, the shielding sheet 13 insertion structure may only include the folding protrusion 133.

[0050] In the above embodiments, the support plate 5 is a sandwich structure, and the middle sandwich space 51 of the sandwich structure forms an insertion slot. In other embodiments, the support plate 5 is a single-layer plate, and an arched section protruding to one side is punched at the edge of the single-layer plate. An insertion hole is formed between the arched section and the surface of the single-layer plate, which serves as an insertion slot for the folding protrusion 133 to be inserted.

[0051] In the above embodiments, the shielding sheet 13 insertion structure provided on the shielding sheet 13 is a protruding structure extending toward the support plate 5. In other embodiments, punching holes can be provided on the shielding sheet 13, and protruding extension ears can be provided on the upper and lower edges of the support plate 5. The extension ears are inserted into the punching holes on the shielding sheet 13, thereby realizing the insertion and fixing of the two.

[0052] In the above embodiments, the support plate 5 of the sandwich structure is folded in half at the front. In other embodiments, it can also be folded in half at the rear end, that is, at the rear end position of the insert tail section 55, while the front ends of the two single-layer plates are brought together and flattened to form the guide end 54.
