The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

In the process of implementing the present invention, the inventor found that, during the process of directly mounting the connector on the filter or mounting the connector on the support base and then mounting the connector on the filter, there is a possibility that a falling object (for example, but not limited to, chips generated by interference fit or screw fit of the two elements) may be generated, and the performance index of the filter may be affected when the falling object falls into the interior of the filter or falls onto an element (for example, but not limited to, a filter element such as a low pass filter element) connected to the inner core of the connector.

Based on this, in order to solve the technical problem that the performance index of the filter is affected by falling objects possibly generated in the connector assembling process when falling objects fall into the inside of the filter or fall onto an element connected with the inner core of the connector, the inventor proposes the following scheme.

Referring to fig. 1 to 6, an embodiment of the present application provides a connector assembly 10 applicable to a filter, the connector assembly 10 includes a connector 11, a fixing portion 12 and a blocking portion 13, wherein:

the connector 11 is a carrier for transmitting a signal of the filter to an external device or transmitting a signal of an external device to the filter. It is understood that the connector 11 may be various types of connectors for being disposed on the filter, such as BMA connector (blind mate connector), SMA connector, SMP connector, MBX connector, PSMP connector, TX connector, etc., but is not limited thereto.

The fixing portion 12 is provided on the outer periphery (outer circumferential direction) of the connector 11, and the fixing portion 12 may be formed integrally with the connector 11 or may be formed separately from the connector 11 and fixed to the outer periphery of the connector 11. The connector 11 can be fixed on the supporting seat through the fixing part 12 and then arranged on the cavity or the cover plate of the filter through the supporting seat, so that the installation of the connector 11 on the filter is realized; of course, in other embodiments, the connector 11 may also be directly fixed to the cavity or the cover plate of the filter through the fixing portion 12, so as to mount the connector 11 on the filter. In the above-mentioned mounting process, i.e. the process of assembling the fixing portion 12 with the supporting base, and the process of assembling the fixing portion 12 with the cavity or the cover plate of the filter, there is a possibility that falling objects, such as metal chips, foreign matters, etc., may be generated, but not limited thereto.

The blocking portion 13 is disposed on the outer circumference of the connector 11 and located on one side of the fixing portion 12, and the blocking portion 13 is located on one side of the fixing portion 12, and the blocking portion 13 may be disposed adjacent to the fixing portion 12, or a gap may be formed between the blocking portion 13 and the fixing portion 12 or other portions or components may be provided. The blocking portion 13 is for blocking or intercepting a falling object generated by the connector 11 fixed to the external member by the fixing portion 12; the external component refers to other components besides the connector assembly 10, that is, other components that need to be connected to the connector assembly 10, such as the supporting seat, the cavity or the cover plate of the filter, and the like. It is understood that the blocking portion 13 may be a sealing ring, a ring-shaped blocking piece structure, a tape winding structure, etc., but is not limited thereto as long as it can be a member that is sealed between the outer circumference of the connector 11 and the inner wall of the external member to block or intercept the falling object.

In the connector assembly 10 provided in the embodiment of the present application, by providing the connector 11 and the fixing portion 12 disposed at the periphery of the connector 11, the connector 11 can be fixed on the supporting seat through the fixing portion 12 and then be disposed on the filter through the supporting seat, or can be directly fixed on the filter through the fixing portion 12, so as to facilitate the installation of the connector 11; meanwhile, by arranging the blocking part 13 which is arranged at the periphery of the connector 11 and is positioned at one side of the fixing part 12, when falling objects such as metal scraps, external impurities and the like are generated in the process that the connector 11 is fixed on the supporting seat through the fixing part 12 or the process that the connector 11 is directly fixed on the filter through the fixing part 12, the blocking part 13 can block the falling objects, for example, in the process that the connector 11 is placed in the groove or the hole, the falling objects can be generated in the process that the fixing part 12 is assembled with the inner wall of the groove or the hole, and the blocking part 13 can block between the periphery of the connector 11 and the inner wall of the groove or the hole, so as to prevent the generated falling objects from falling into the interior of the filter or falling onto elements (such as low-pass filter elements and the like) connected with the inner core of the connector 11 to influence the performance index of the filter, thereby effectively reducing the possibility that the connector 11 is mounted on the filter to influence the performance index of the filter, the product yield and performance can be improved.

In one embodiment, referring to fig. 1 and fig. 4, the connector 11 has a first connection end 1101 and a second connection end 1102, which are oppositely disposed, the first connection end 1101 is used for connecting internal components (such as but not limited to lowpass, resonator, etc.) of the filter, and the second connection end 1102 is used for connecting an external device, that is, an external device to which the filter needs to be connected through the connector 11; the blocking portion 13 is located between the first connection end 1101 and the fixing portion 12, that is, the blocking portion 13 is closer to the first connection end 1101 than the fixing portion 12.

With this arrangement, when the connector 11 is vertically mounted on the supporting base through the fixing portion 12 in the direction from the second connecting end 1102 to the first connecting end 1101, or when the connector 11 is vertically mounted on the cavity or the cover plate of the filter through the fixing portion 12 in the direction from the second connecting end 1102 to the first connecting end 1101, the falling object will fall down along the second connecting end 1102 in the direction of the first connecting end 1101, and at this time, the blocking portion 13 is located between the fixing portion 12 and the first connecting end 1101, so as to block or intercept the falling object, and prevent the falling object from falling down into the interior of the filter or falling onto an element (such as a low pass filter element) connected to the inner core of the connector 11, thereby affecting the performance index of the filter.

The position where the stopper 13 is provided is not limited to this. Optionally, in some other embodiments, the blocking portion 13 may also be disposed between the fixing portion 12 and the second connecting end 1102.

Alternatively, the connector 11 may include an outer shell, an inner core disposed through the outer shell, and an insulator disposed between the outer shell and the inner core, wherein one end of the inner core forms a first connection end 1101, and the other end of the inner core forms a second connection end 1102 with the outer shell. Of course, in other embodiments, the outer shell may not be provided, and only the insulator and the inner core penetrating through the insulator may be included.

Optionally, in one embodiment, an outer conductor is disposed on the connector 11 near the second connection end 1102 to perform functions of installing, debugging and shielding signals. The outer conductor may be coaxially disposed with the first connection end 1101 and connected to the connector 11, or the outer conductor may be integrally formed with the connector 11.

In one embodiment, referring to fig. 1, 3 and 8, the fixing portion 12 and the connector 11 are of an integral structure, that is, the fixing portion 12 and the connector 11 form a single component, and specifically, the fixing portion 12 may be integrally formed with a housing of the connector 11. The fixing portion 12 is a knurled structure, and it is understood that the knurled structure may be a straight knurled structure (or called a vertical knurled structure), a cross-hatched knurled structure, etc., but is not limited thereto, and may also be other knurled structures with regular or irregular shapes. Fig. 1 and 3 show an exemplary case where the knurled structure is a straight knurled structure.

Due to the arrangement, the connector 11 is directly pressed on the supporting seat through the knurled structure, or is pressed on the cavity or the cover plate of the filter through the knurled structure, the installation is more convenient, and the connector 11 does not need to be provided with the fixing part 12 formed in a split mode firstly and then arranged on the supporting seat or the filter through the fixing part 12, so that the working procedure is simplified, the working time is saved, the materials are saved, the cost is reduced, and the assembly efficiency is improved; moreover, due to the fact that tolerance exists between the fixing portion 12 and the connector 11 which are formed in a split mode, and tolerance also exists between the fixing portion 12 and the supporting seat or the filter, so that multi-level tolerance exists, the fixing portion 12 and the supporting seat or the filter cannot be installed due to looseness or tightness, and the material rejection rate is high. Meanwhile, the fixing part 12 is arranged to be of a knurled structure, and the inner wall of the groove or the hole for installing the connector 11 on the supporting seat or the filter can be a smooth surface, so that the filtering elements such as a low pass filter and the like connected with the inner core of the connector 11 can be smoothly placed in the groove or the hole, and the installation is facilitated.

The fixing portion 12 is not limited to a knurled structure. Alternatively, in some other embodiments, the fixing portion 12 may be an external thread structure to facilitate the connector 11 to be screwed with the support base or the filter through the external thread structure.

It should be noted that the fixing portion 12 is not limited to the structure integrated with the connector 11. Alternatively, in some other embodiments, the fixing portion 12 and the connector 11 may be fixed by being formed as a separate body. In one embodiment, referring to fig. 4 to 6, the fixing portion 12 may be a cylindrical structure and is sleeved on the connector 11, specifically, the outer circumferential surface of the connector 11 may be provided with a knurled structure, the connector 11 is in interference fit with the inner wall of the cylindrical structure through the knurled structure of the outer circumferential surface, of course, the outer circumferential surface of the connector may also be provided with an external thread structure, and the connector 11 is in threaded connection with the inner wall of the cylindrical structure through the external thread structure of the outer circumferential surface. The outer peripheral surface of the tubular structure is provided with a knurled structure or an external thread structure, so that the connector 11 is in interference fit with the supporting seat or the filter through the knurled structure on the outer peripheral surface of the tubular structure, or is in threaded connection fit with the supporting seat or the filter through the external thread structure on the outer peripheral surface of the tubular structure.

In one embodiment, referring to fig. 2, 3 and 8, the blocking portion 13 is a sealing ring, and the sealing ring is sleeved on the outer circumference of the connector 11. Specifically, the seal ring may be fitted around the outer periphery of the housing of the connector 11. Alternatively, the seal may be an O-ring seal to facilitate mating with the outer circumference of the connector 11. It is to be understood that any conventional seal ring may be used, for example, a rubber seal ring made of various materials, but not limited thereto.

Due to the arrangement, the blocking part 13 is a sealing ring, so that the structure is simple, the connector assembly is easy to directly install on a connector, and the production and manufacturing cost of the connector assembly 10 is low; and when the connector 11 is fixed in the groove or hole on the supporting seat, the cavity of the filter or the cover plate through the fixing part 12, the sealing ring can be sealed between the periphery of the connector 11 and the inner wall of the groove or hole, so that the effect of blocking or intercepting the falling objects is ensured.

Alternatively, in an embodiment, referring to fig. 2, 3 and 8, an outer annular groove 1103 is formed on an outer circumferential surface of the connector 11, the outer annular groove 1103 is annular, and the sealing ring is disposed in the outer annular groove 1103. Specifically, the outer circumferential surface of the housing of the connector 11 is opened with an outer ring groove 1103.

So set up, outer annular groove 1103 can carry on spacingly to the sealing washer, not only do benefit to the sealing washer and install in the outside of connector 11 steadily, and when connector 11 is fixed in the supporting seat through fixed part 12, the cavity of wave filter or groove or the hole on the apron, the sealing washer receives the limiting displacement of outer annular groove 1103, along with putting into of connector 11 and remove simultaneously, be difficult for taking place the skew relative to connector 11 when the atress, so as to do benefit to the leakproofness and block better between the periphery of connector 11 and the inner wall in groove or hole and be difficult for producing the gap, and then improve the effect of blockking or intercepting the junk.

Of course, in other embodiments, the outer circumferential surface of the connector 11 may not be provided with the outer ring groove 1103. Alternatively, the packing may be directly fitted to the outer circumferential surface of the connector 11.

Alternatively, in one embodiment, referring to fig. 1, 2 and 8, the sealing ring is an elastically deformable sealing ring, i.e. the sealing ring is made of an elastically deformable material. The outer diameter of the sealing ring is larger than that of the fixing part 12; wherein, the external diameter of sealing washer is the maximum diameter of sealing washer, and the external diameter of fixed part 12 is the maximum diameter of fixed part 12.

So set up, when connector 11 is fixed in groove or the hole on the cavity or the apron of supporting seat, wave filter through fixed part 12, because the external diameter of sealing washer is greater than the external diameter of fixed part 12, and the sealing washer can take place elastic deformation for the sealing washer is extruded mutually by the periphery of connector 11 and the inner wall in groove or hole promptly, in order to do benefit to the leakproofness that improves the sealing washer and seal between the periphery of connector 11 and the inner wall in groove or hole, and then improves blockking or the interception effect to the junk.

The structure of the stopper 13 is not limited to the seal ring. Optionally, in some other embodiments, referring to fig. 5, fig. 6 and fig. 9, the blocking portion 13 may be a blocking plate structure, the blocking plate structure is provided with a through hole 1301, the blocking plate structure is a substantially annular plate structure, and the blocking plate structure is sleeved on the connector 11 through the through hole 1301. Alternatively, the flap structure may be interference fitted with the outer circumferential surface of the connector 11 through the through hole 1301. Of course, in other embodiments, the flap structure may be over-fit or clearance-fit with the outer peripheral surface of the connector 11 through the through-hole 1301. Alternatively, the baffle structure may be a metallic material or a non-metallic material.

Referring to fig. 7 to 9, a filter assembly 100 is further provided in an embodiment of the present application, the filter assembly 100 includes a support base 20, a low pass assembly 30 and the connector assembly 10 of any of the above embodiments. The supporting base 20 has a low-pass groove 201 and a mounting groove 202 communicated with the low-pass groove 201, the mounting groove 202 can be disposed at one end of the low-pass groove 201, and of course, in some other embodiments, the mounting groove 202 can also be disposed between two opposite ends of the low-pass groove 201, i.e., in the middle of the low-pass groove 201. The low pass assembly 30 is disposed in the low pass slot 201. The connector 11 is fixed to the inner wall of the mounting groove 202 by the fixing portion 12, and the support base 20 is an external element, and the blocking portion 13 is located between the inner wall of the mounting groove 202 and the outer periphery of the connector 11. The inner core of the connector 11 is connected to the low pass assembly 30 to facilitate signal transmission between the connector 11 and the low pass assembly 30, and specifically, the first connection end 1101 of the connector 11 is electrically connected to the low pass assembly 30, where the low pass assembly 30 is an internal element of the filter.

Since the filter assembly 100 provided in the embodiment of the present application employs the connector assembly 10 of the foregoing embodiment, the filter assembly 100 also has the technical effects brought by the technical solutions of the connector assembly 10 of any of the foregoing embodiments. When the connector 11 is fixed on the inner wall of the mounting groove 202 through the fixing portion 12, a falling object may be generated in the process of assembling the fixing portion 12 and the inner wall of the mounting groove 202, the blocking portion 13 is disposed between the inner wall of the mounting groove 202 and the periphery of the connector 11, the falling object can be effectively blocked or intercepted, and the falling object can be limited between the fixing portion 12 and the blocking portion 13, so as to prevent the falling object from falling into the low pass groove 201 or onto the low pass assembly 30 to influence the performance index of the filter adopting the filter assembly 100.

Moreover, when the installation groove 202 and the low pass groove 201 are coaxially arranged, the inner core of the connector 11 may need to be connected to the low pass assembly 30 first, and then the connector 11 and the low pass assembly 30 are integrally placed into the installation groove 202 and the low pass groove 201 at the same time, if there is no blocking portion 13, the generated falling object will remain between the low pass assembly 30 and the connector 11, and the blocking portion 13 is arranged to block and limit the falling object between the fixing portion 12 and the blocking portion 13, without obstructing the low pass assembly 30.

Meanwhile, the connector assembly 10 and the low-pass assembly 30 are assembled on the same supporting seat 20, which is beneficial to saving the installation space of the low-pass assembly 30, and further saving the cavity space of the filter, and improving the space utilization rate of the filter.

It is to be understood that the low pass component 30 can be any one of the existing low pass components or a low pass component modified from the existing low pass component. Optionally, the low pass assembly 30 includes a low pass and an insulator disposed outside the low pass, which may be, but is not limited to, an insulating sleeve, an insulating coating, and the like.

In one embodiment, referring to fig. 8 and 9, the inner diameter of the mounting groove 202 is larger than the inner diameter of the low pass groove 201, and accordingly, the outer diameter of the fixing portion 12 is larger than the outer diameter of the low pass assembly 30.

Due to the arrangement, the low-pass assembly 30 is smoothly placed into the low-pass groove 201 from the mounting groove 202, the low-pass assembly 30 is convenient to mount, and blocking is not easy to occur; further, even if the inner wall of the mounting groove 202 is provided with an internal thread for screw-fitting with the fixing portion 12, it is not easy to hinder the insertion of the low pass unit 30.

Of course, in other embodiments, the inner diameter of the mounting groove 202 may be the same as the inner diameter of the low pass groove 201.

In one embodiment, referring to fig. 8, the blocking portion 13 is a sealing ring. An outer circumferential surface of the connector 11 is formed with an outer circumferential groove 1103, and a seal ring is positioned in the outer circumferential groove 1103. Since the seal ring needs to block the falling objects, a portion of the seal ring protrudes from the outer ring groove 1103 to facilitate the engagement with the inner wall of the mounting groove 202.

So set up, outer annular groove 1103 can carry on spacingly to the sealing washer, makes it more stably sealed between the periphery of connector 11 and the inner wall of mounting groove 202, and the sealing washer can form the step cooperation with the inner wall of outer annular groove 1103, can improve sealing performance.

In other embodiments, the outer circumferential surface of the connector 11 may not be provided with the outer annular groove 1103. Alternatively, only the inner wall of the mounting groove 202 may be provided with an inner ring groove, and the sealing ring is located in the inner ring groove. Alternatively, the outer circumferential surface of the connector 11 may be provided with an outer ring groove 1103, the inner wall of the mounting groove 202 may be provided with an inner ring groove, and the sealing rings may be located in both the outer ring groove 1103 and the inner ring groove.

In one embodiment, referring to fig. 7 to 9, the supporting base 20 has a low pass seating groove 203, and the low pass seating groove 203 is located at one side of the low pass groove 201. The filter assembly 100 includes a low pass structural assembly 40, it being understood that the low pass structural assembly 40 may include a low pass and an insulator disposed outside the low pass. The low pass structure element 40 is disposed in the low pass placing groove 203, and the low pass structure element 40 is connected to the low pass element 30, specifically, the low pass of the low pass structure element 40 can be electrically connected to the low pass of the low pass element 30 through a conductive structure. Alternatively, the low pass placement groove 203 may be parallel to the low pass groove 201, i.e., the low pass placement groove 203 is disposed in parallel with the low pass groove 201. Alternatively, the length of the low pass seating groove 203 may be smaller than the length of the low pass groove 201, and of course, may be greater than or equal to the length of the low pass groove 201.

So set up, low logical groove 201 and low pass arrangement groove 203 can set up low pass subassembly 30 and low pass structure subassembly 40 respectively to do benefit to and set up a plurality of low passes on supporting seat 20, not only can satisfy the assembly demand to the low pass of different length, and the assembly is more compact, does benefit to the space utilization who improves the wave filter.
