In the cover assembly according to the present utility model, the cover body and the base body are fastened to each other in the height direction, thereby enclosing a space for accommodating the electronic assembly between the cover body and the base body.

The technical idea of the present utility model is first briefly explained. In the cap assembly of the present utility model, a cap body, a base body, and securing assemblies are assembled together, each securing assembly including an insert and a connector. The side wall of the housing is formed with at least a pair of mounting slots each having an opening open toward the outside of the housing assembly and a first via hole communicating with the corresponding mounting slot. The side wall of the substrate is provided with a second via hole communicated with the corresponding first via hole. Each insert is inserted into the mounting groove through the above-mentioned opening of the mounting groove, whereby the insert can be mounted in the mounting groove. The insert is also formed with a connection hole in communication with the first via. The connecting piece is inserted into the connecting hole through the two through holes and then fixed with the insert, so that the cover body and the base body can be fixed together by matching the connecting piece and the insert. In this way, a cover assembly is provided that is simple in construction and easy to assemble. In the cover assembly, the fixing assembly between the cover body and the base body is formed by the insert and the connecting piece, and the insert is a single piece, so that the fixing assembly has a simple structure. In addition, the mounting groove of the cover body for mounting the insert is formed in the side wall thereof and is opened toward the outside of the cover assembly, so that the inner space of the cover assembly is not greatly occupied, and the cover body is easily molded.

The structure of a cap assembly according to an embodiment of the present utility model will be described below with reference to the drawings.

As shown in fig. 1A to 1D, the cap assembly according to an embodiment of the present utility model includes a cap body 1, a base body 2, a plurality of fixing assemblies (each including a pair of an insert 3 and a connector 4 that are mated with each other), and a seal ring 5, which are assembled together. The plurality of fastening assemblies are distributed at intervals over the entire circumference of the cap assembly, by means of which the cap body 1 and the base body 2 can be fastened together. For each fixing assembly, the insert 3 is inserted into a corresponding mounting groove 11c of the cover 1, and the connector 4 is inserted into the insert 3 through the base 2 and the cover 1 and cooperates with the insert 3 to fix the cover 1 and the base 2 together. In addition, a seal ring 5 is interposed between the cover 1 and the base 2 to seal the gap between the cover 1 and the base 2. The specific construction of the hood assembly is described below.

In the present embodiment, the cover 1 may be made of a nonmetallic material such that electromagnetic waves generated by, for example, an electronic component mounted in the cover assembly can propagate through the cover 1 to the outside of the cover assembly, and the electronic component can collect electromagnetic waves reflected through the cover 1. As shown in fig. 1A to 1D, the cover 1 includes a first side wall 11 and a top wall 12 formed integrally, the first side wall 11 standing from the entire outer peripheral portion of the top wall 12 toward the base 2, the first side wall 11 extending in the height direction H. Further, as shown in fig. 1B to 1D, the first side wall 11 is formed with a plurality of pairs of mounting grooves 11c and first vias 11h1. The mounting groove 11c is formed with a first opening 11o in the outer peripheral surface of the first side wall 11, the first opening 11o being open to the outside of the cover assembly. The first via holes 11H1 extend linearly along the height direction H, and the first via holes 11H1 communicate with the corresponding mounting grooves 11 c. One end of the first via hole 11H1 is formed with a second opening 31o on a surface (second mounting surface 11 s) of the mounting groove 11c located at the bottom in the height direction H, and the other end of the first via hole 11H1 is formed with an opening communicating with the second via hole 21H on a surface of the first sidewall 11 facing the second sidewall 21 (i.e., a surface of the first sidewall 11 abutting against the second sidewall 21). In addition, the cross-sectional dimension of the first via hole 11h1 is larger than the cross-sectional dimension of the screw 42 of the connector 4, so that even if misalignment occurs between the cover 1 and the base 2, since the dimension of the first via hole 11h1 is set larger than the dimension of the screw 42, such displacement can be compensated.

In the present embodiment, the base 2 may be made of a metal material so that the base 2 has sufficient structural strength to support and protect electronic components mounted in, for example, a cap assembly. As shown in fig. 1A to 1C, the base 2 includes a second side wall 21 and a bottom wall 22 formed integrally, the second side wall 21 standing from the entire outer peripheral portion of the bottom wall 22 toward the cover 1, the second side wall 21 extending in the height direction H. Further, as shown in fig. 1B and 1C, the second side wall 21 includes a standing wall portion 211 and a flange portion 212 formed integrally. The flange 212 is fixed to one end of the standing wall 211 and protrudes toward the outside of the cover assembly, and the one end of the standing wall 211 and the flange 212 abut against the first side wall 11. The second sidewall 21 has a second via hole 21H formed in the flange 212 and communicating with the first via hole 11H1, and the second via hole 21H extends linearly in the height direction H. One end of the second via hole 21h is formed with an opening communicating with the first via hole 11h1 on a surface of the flange portion 212 facing the first side wall 11 (i.e., a surface of the second side wall 21 abutting the first side wall 11), and the other end of the second via hole 21h is formed with an opening toward the outside of the cap assembly on a surface of the flange portion 212 facing away from the first side wall 11. In this way, it is possible to facilitate the operation of the connection member 4 from the side facing away from the first side wall 11, so that the connection member 4 is inserted into the connection hole 31h via the second via hole 21h and the first via hole 11h1 in order, and the subsequent assembly work of the connection member 4 with the connection hole 31h is completed. In addition, the cross-sectional dimension of the second through hole 21h is larger than the cross-sectional dimension of the screw 42 of the connector 4, so that even if misalignment occurs between the cover 1 and the base 2, since the dimension of the second through hole 21h is set larger than the dimension of the screw 42, such displacement can be compensated.

In the present embodiment, as described above, each of the fixing members includes the paired insert 3 and the connecting piece 4 fitted to each other, which are capable of firmly fixing the cover 1 and the base 2 together, and the structure of the fixing members and the cooperation of the cover 1 and the base 2 will be described below.

Specifically, the insert 3 may be made of the same or different metal material as the connecting member 4, and all portions of the insert 3 are integrally formed, thereby being formed as a single piece. As shown in fig. 1A to 1D, the insert 3 is inserted into the mounting groove 11c through the first opening 11o and fixed to the cover 1. Specifically, referring further to fig. 2A to 2C, the insert 3 includes a body portion 31, a cover portion 32, a first overlap portion 33, and a second overlap portion 34, which are integrally formed. The first and second overlap portions 33 and 34 are located at both sides of the main body portion 31, and the first and second overlap portions 33 and 34 protrude from the main body portion 31 toward both sides of the main body portion 31, respectively. The cover portion 32 is integrally formed with the main body portion 31, the first overlap portion 33, and the second overlap portion 34. In a state where the insert 3 is inserted into the mounting groove 11c, the main body portion 31, the first overlap portion 33, and the second overlap portion 34 match the structure of the cover 1 within the mounting groove 11c, the cover portion 32 serves to close the first opening 11o of the mounting groove 11c, and the outer surface of the cover portion 32 is flush with the outer surface of the cover 1.

Further, as shown in fig. 2A to 2C, the insert 3 is formed with a connection hole 31H extending in the height direction H in the main body portion 31. In the present embodiment, the connection hole 31h is formed with an internal thread for screw-coupling with an external thread of the screw 42 of the connection member 4. The connection hole 31H extends linearly along the height direction H, and one end of the connection hole 31H forms an opening communicating with the first via hole 11H1 on the first mounting surface 31s of the main body portion 31 of the insert 3, the first mounting surface 31s and the second mounting surface 11s facing each other in the height direction H. In the present embodiment, as shown in fig. 1B, with the insert 3 shown in the drawing, the insert 3 is inserted into the mounting groove 11c along an insertion direction (from the right side toward the left side in the drawing) perpendicular to the height direction H. The first mounting surface 31s of the main body portion 31 of the insert 3 extends obliquely with respect to the insertion direction, specifically extends from the right side toward the left side in the drawing while extending obliquely toward the upper side in the drawing. The cover 1 has a second mounting surface 11s formed at the bottom of the mounting groove 11c, and the second mounting surface 11s and the first mounting surface 31s extend in the same direction to achieve surface matching with the first mounting surface 31 s. By adopting the technical scheme, on one hand, the insert 3 is inserted into the mounting groove 11c through the first mounting surface 31s and the second mounting surface 11s to be guided, so that the assembly of the insert 3 and the cover body 1 is facilitated; on the other hand, the design of the first mounting surface 31s also facilitates demolding of the cover 1 after molding. Further, as shown in fig. 1C and fig. 2A to 2C, the insert 3 is formed with two stopper protrusions 31p on the first mounting surface 31s of the main body 31, the cover 1 is formed with corresponding stopper holes 11h2, and the stopper holes 11h2 have openings on the second mounting surface 11 s. In the case where the outer contours of both the insert 3 and the mounting groove 11c substantially match, the stopper projection 31p and the stopper hole 11h2 cooperate, so that the relative position of the insert 3 and the cover 1 can be defined. Further, the connection hole 31h forms a second opening 31o for communicating with the first via hole 11h1 on the first mounting surface 31s, and two limit protrusions 31p are provided not only on the first mounting surface 31s but also on both sides of the second opening 31o with the two limit protrusions 31p being offset from the second opening 31 o. Like this, utilize spacing protruding 31p and spacing hole 11h2 cooperation, not only carry out spacingly to the relative position after inserts 3 and the cover body 1 are installed, avoid the condition that inserts 3 did not install in place, can also be favorable to first via hole 11h1 to aim at with connecting hole 31h, but also can prevent that inserts 3 from unexpected deviating from after installing in place.

Further, as shown in fig. 1C and 1D, the cover body 1 is formed with a first step structure 11s1 and a second step structure 11s2 in the mounting groove 11C, the first step structure 11s1 and the second step structure 11s2 being located at two opposite wall portions of the mounting groove 11C, respectively. In a state where the insert 3 is inserted into the mounting groove 11C, as shown in fig. 1C, the first overlap portion 33 is supported by the step surface of the first step structure 11s1, and the second overlap portion 34 is supported by the step surface of the second step structure 11s 2. By the overlap portions 33, 34 supported by the step structures 11s1, 11s2, the pressure of the insert 3 to the portion of the cover body 1 at the bottom of the mounting groove 11c can be reduced, and the portion of the cover body 1 at the bottom of the mounting groove 11c can be prevented from being accidentally deformed or damaged due to excessive pressure of the insert 3 to the portion.

Further, as shown in fig. 2A and 2B, the insert 3 is formed with a dividing slit 3h at a portion where both the body portion 31 and the cover portion 32 are connected, so that the body portion 31 and the cover portion 32 are partially separated by the dividing slit 3 h. The extending direction of the dividing slit 3h is the same as the extending direction of the connecting hole 31h and the dividing slit 3h penetrates the insert 3, thereby forming a thin wall portion between the dividing slit 3h and the connecting hole 31h. In this way, even if the thin portion deforms and protrudes inward of the dividing slit 3h after the connector 4 is inserted into the connecting hole 31h, the thin portion does not abut or press the lid portion 32. By providing the slit 3h, the influence of the deformation of the main body 31 on the shape of the cover 32 after the connector 4 is inserted into the connection hole 31h is greatly reduced.

In the present embodiment, the connecting member 4 may be made of the same metal material as the insert 3, and thus even if the insert 3 and the connecting member 4 shrink or expand under the influence of the temperature of the surrounding environment or the like, the connection stability between the two is not affected. As shown in fig. 1A to 1C, the connector 4 is inserted into the connection hole 31h via the second via hole 21h and the first via hole 11h1 and is fixed to the insert 3 by screw connection, so that the connector 4 cooperates with the insert 3 to fix the cover 1 and the base 2 together. Specifically, as shown in fig. 1B and 1C, the connection member 4 includes a screw cap 41 and a screw 42 formed integrally, the screw 42 extending linearly from the screw cap 41 in the height direction H, the screw 42 being inserted into the connection hole 31H and screwed with the connection hole 31H, so that a part of the cover 1 and a part of the base 2 are clamped between the screw cap 41 and the insert 3, thereby fixing the cover 1 and the base 2.

In the present embodiment, as shown in fig. 1B, the second side wall 21 is formed with a ring groove 21c, the ring groove 21c having an opening opened toward the first side wall 11, and a seal ring 5 made of an elastic material such as rubber is accommodated in the ring groove 21 c. The second side wall 21 is formed with a bead 11p protruding into the annular groove 21c, whereby the bead 11p presses against the seal ring 5 so that the seal ring 5 can be tightly clamped between the cover 1 and the base 2, whereby the gap between the cover 1 and the base 2 can be effectively sealed, preventing foreign matter from entering the inside of the cover assembly via the gap. In fact, the above-mentioned sealing ring 5 and the structure corresponding to the sealing ring 5 are not essential, and in the alternative, the sealing ring 5 may be omitted.

For example, the insert 3 may not be internally threaded in the coupling hole 31h, and the coupling member 4 may be a self-tapping screw, with corresponding threads being formed in the insert 3 by the coupling member 4 during insertion of the coupling member 4 into the coupling hole 31h of the insert 3.

In the above embodiment, it was explained that the insert 3 is formed with the dividing slits 3h to reduce deformation of the cover portion 32 due to insertion of the connecting member 4 into the connecting hole 31h, and in practice the body portion 31 of the insert 3 may be formed with a plurality of other holes to absorb such deformation, the holes being distributed apart from the connecting hole 31h, each of the holes extending in the same direction as the connecting hole 31h. By providing these holes, the deformation amplitude of the outer shape of the body portion 31 after the connector 4 is inserted into the connection hole 31h can be reduced.

It will be appreciated that the cap assembly according to the present utility model is simple in construction and easy to assemble. In the cap assembly of the present utility model, the insert 3 is a single piece, and in particular, the insert 3 may be made of a single material, simplifying construction as compared to using a separate insert assembly. In addition, the insert 3 can be assembled to the cover 1 and the connector 4 can be inserted into the insert 3 from the outer sides of both the cover 1 and the base 2, thereby simplifying the assembly process, occupying less internal space of the cover assembly, and not complicating the molding process of the cover 1.
