Description

Technical Field

[0001] The present invention relates to a connector for preventing characteristic impedance mismatch, and more specifically, to a connector for preventing characteristic impedance mismatch that can be manufactured to be thinner while maintaining the desired impedance matching. Background Technology

[0002] Typically, radio frequency (RF) connectors for wireless communication are designed with a characteristic impedance of 50Ω. This characteristic impedance is based on the connector mating condition.

[0003] In microwave engineering, it is known that the impedance with the best power transmission characteristics of electromagnetic energy is 33Ω, and the impedance with the least signal waveform distortion is about 75Ω. Therefore, the intermediate value of 50Ω, which satisfies these two characteristics well, is used as the characteristic impedance.

[0004] In particular, since the entire circuit of a mobile communication system is designed for 50Ω, there is no compatibility when the connector is looking for different impedances. As the difference between the characteristic impedance of the connector and 50Ω increases, there are problems such as signal waveform distortion or power transmission characteristics deterioration.

[0005] This problem of signal waveform distortion or deterioration in power transmission characteristics becomes more pronounced during the assembly tolerances of RF connectors that electrically connect the contacts between two substrates.

[0006] For example, Figure 1 A cross-sectional view of one of the drawings in Korean Patent No. 10-1992258 (published on June 25, 2019) (hereinafter referred to as the "Patent") is shown below. Figure 1 As shown, between the first panel and the second panel corresponding to the two substrates, there are: fixing modules 210 and 220; and contact modules 110 and 120, which are movably combined with fixing modules 210 and 220. The internal space between fixing modules 210 and 220 and contact modules 110 and 120 is designed with characteristic impedance to prevent mismatch.

[0007] More in detail, such as Figure 1 As shown, fixing modules 210 and 220 include: a fixing body 210 made of conductive material, forming a hollow 210a; and a fixing pin 220 configured to contact the first panel within the fixing body 210 via a fixing insulator 230. Contact modules 110 and 120 include: a contact body 110 made of conductive material, forming a hollow 110a; and a contact pin 120 configured to contact the second panel within the contact body 110 via a contact insulator 130.

[0008] The hollow 210a of the fixing body 210 and the hollow 110a of the contact body 110 include an elastic component 410 in the form of a helical spring. The elastic component 410 is fixed by a fixing insulator 230 and a contact insulator 130 provided with a dielectric having a specified dielectric constant. One end of the elastic component 410 is supported by the fixing body 210 and the other end is supported by the contact body 110. By compressing and elongating the external force transmitted during the assembly process, it elastically supports the contact body 110 toward the second panel side to maintain a specified contact force.

[0009] However, the advantage of the authorized patent is that it can easily absorb the assembly tolerance between the first panel and the second panel during the assembly process of the fixed modules 210, 220 and the contact modules 110, 120. However, it has the following disadvantage: in order to prevent the above-mentioned characteristic impedance mismatch, the elastic component 410 in the form of a helical spring should be designed at least outside the hollow 210a of the fixed body 210 and the hollow 110a of the contact body 110.

[0010] That is, in the authorized patent, such as Figure 1 As shown, one end of the elastic member 410 is configured to support the fixed body 210 at a position separated from the hollow 210a of the fixed body 210 by an elastic member support groove 217 provided in the form of a groove on the outside of the fixed body 210. The other end of the elastic member 410 is designed to be elastically supported at a portion corresponding to the outside of the hollow 110a of the contact body 110. Therefore, the following problem exists: in order to install the elastic member 410, the diameter of the fixed body 210 should be designed to be at least larger than the diameter of the contact body 210. Figure 1 The attached figure's reference numeral D is approximately twice as large, thus limiting the product's slim design. Summary of the Invention

[0016] Problem-solving methods

[0017] An embodiment of the characteristic impedance mismatch prevention connector of the present invention includes: a fixed module, fixed by welding to one of two parallel panels (hereinafter referred to as "first panel"), having an impedance matching space (hereinafter simply referred to as "matching space") inside; a movable module, configured to move into and out of the matching space of the fixed module, and configured to contact the other of the two panels (hereinafter referred to as "second panel"); and an elastic member, disposed inside the matching space of the fixed module, for elastically supporting the movable module toward the second panel side, the movable module including: a movable terminal pin, made of conductive material, one end contacting the second panel, and the other end establishing an electrical signal line between the fixed module and the first panel; a movable insulator having a predetermined dielectric constant, disposed in the matching space to achieve a characteristic impedance matching design value, having a portion surrounding the outer peripheral surface of the movable terminal pin; and an outer conductor portion disposed between the movable insulator and the fixed module, configured such that the elastic member does not directly contact at least one of the movable insulator and the movable terminal pin, for transmitting the elastic support force of the elastic member to the movable insulator.

[0057] Hereinafter, various embodiments of the characteristic impedance mismatch prevention connector of the present invention will be described in detail with reference to the accompanying drawings.

[0058] It should be noted that in applying reference numerals to the structural elements of the various figures, the same reference numerals are applied to the same structural elements as much as possible, even when they are shown in different figures. Furthermore, in describing the present invention, detailed descriptions of related well-known structures or functions will be omitted when it is determined that such detailed descriptions may obscure the spirit of the invention.

[0059] In describing the structural elements of this invention, terms such as first, second, A, B, (a), and (B) may be used. These terms are used merely to distinguish one structural element from another, and the nature, order, or sequence of the corresponding structural elements are not limited thereto. Furthermore, unless otherwise defined, all terms, including technical or scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Commonly used terms, such as those defined in dictionaries, should be interpreted as having the meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this invention.

[0060] Figure 2 and Figure 3 A partial cross-sectional view illustrating various configuration examples of the connector for preventing characteristic impedance mismatch according to the present invention.

[0061] like Figure 2As shown, the characteristic impedance mismatch prevention connector of the present invention performs the function of establishing an electrical signal line between the first panel B1 and the second panel B2.

[0062] Wherein, the first panel B1 and the second panel B2 can be printed circuit boards (PCBs). Furthermore, the first panel B1 can be a printed circuit board, and the second panel B2 can be a printed circuit board (see reference). Figure 2 ) or a radio frequency connection part having antenna elements, etc. (not shown) (see reference) Figure 3 ).

[0063] A cover shell 5 is separately provided between the first panel B1 and the second panel B2, so as to securely fix the characteristic impedance mismatch prevention connector of the present invention.

[0064] More in detail, such as Figure 2 As shown, in one embodiment of the characteristic impedance mismatch prevention connector of the present invention, one end is welded and fixed to the first panel B1 by welding, and the other end is fixed to the cover shell 5 for support. The outer side is brought into contact with the second panel B2 by pressing against it, thereby establishing an electrical signal line between the first panel B1 and the second panel B2.

[0065] In order to make electrical signal connection with the second panel B2, a signal channel 7 of a specified diameter is formed in the cover shell 5 with an opening. The other end of the characteristic impedance mismatch prevention connector of the present invention passes through and is exposed through the signal channel 7, and the second panel B2 can be closely attached to and in contact with the part exposed through the signal channel 7.

[0066] Reference Figure 2 In another embodiment of the connector for preventing characteristic impedance mismatch of the present invention, a cover signal leakage shielding component 70 and a second panel signal leakage shielding component 80 may also be provided at the other end (the ends of the fixed module F and the moving module M described later). The cover signal leakage shielding component 70 supports and covers the inner edge of the signal channel 7 of the cover housing 5, and the second panel signal leakage shielding component 80 supports and covers the outer side of the contact portion (not shown) of the second panel B2.

[0067] It can perform the following functions: preventing signals from leaking to the outside from the electrical signal line that forms approximately the middle of the cover signal leakage shielding component 70 and the second panel signal leakage shielding component 80. In addition, the cover signal leakage shielding component 70 and the second panel signal leakage shielding component 80 are made of conductive material and also function as grounding terminals. Furthermore, they are made of elastic material, so that even when external forces such as assembly forces are transmitted, they are stably and elastically supported by the cover housing 5 and the second panel B2 and perform functions such as absorbing assembly tolerances.

[0068] Reference Figure 3 In one embodiment of the characteristic impedance mismatch prevention connector of the present invention, it is not necessarily required to provide a covered signal leakage shielding component 70. Signal leakage can be adequately prevented by the signal shielding of the fixed housing 10 of the fixed module F and the outer conductor portion 40' of the moving module M, as described later. Therefore, with Figure 2 Unlike the previous version, by retaining only the second panel signal leakage shielding component 80 and removing the cover signal leakage shielding component 70, it has the advantage of reducing manufacturing costs.

[0069] On the other hand, when the second panel B2 is provided with a radio frequency connector having an antenna element, the second panel B2 may also include: a contact terminal B21; a fixing block B22 for fixing the contact terminal B21; and a filter-side signal leakage shielding component B25, configured to prevent signal leakage outside the edge of the signal channel 7 of the cover housing 5.

[0070] One end of the filter-side signal leakage shielding component B25 can be fixedly mounted on the shielding component mounting groove B23 formed in the recess of the second panel B2, and the other end can be elastically supported by the outer side of the signal channel 7 of the cover shell 5.

[0071] Figures 4 to 6 Cross-sectional views illustrating various embodiments of the connector for preventing characteristic impedance mismatch according to the present invention.

[0072] For ease of description, the following will refer to Figure 4 The embodiment described herein is referred to as the "first embodiment" and will be referred to herein. Figure 5 The embodiment referred to as the "second embodiment" will be referred to Figure 6 The embodiment described herein is referred to as the "third embodiment".

[0073] like Figure 4 As shown, the connector for preventing characteristic impedance mismatch in the first embodiment may include a fixed module F and a movable module M.

[0074] The fixing module F is fixed to the first panel B1 of the two parallel panels by welding, and an impedance matching space 90 (hereinafter referred to as "matching space") can be set inside it.

[0075] The moving module M is configured to move inside and outside the matching space 90 of the fixed module F, and can be set to contact the second panel B2.

[0076] In addition, such as Figure 4As shown, the connector for preventing characteristic impedance mismatch in the first embodiment may further include an elastic member 60, which is disposed inside the matching space 90 of the fixed module F and is used to elastically support the movable module M toward the second panel B2 side.

[0077] In the characteristic impedance mismatch prevention connector of the first embodiment formed with the structure described above, a portion of the fixed module F and the movable module M are configured to be energized to each other, thereby establishing the aforementioned electrical signal line.

[0078] More in detail, such as Figure 4 As shown, the fixed module F may include: a fixed housing 10 having a mating space 90; a fixed insulator 30 configured to shield one side of the mating space 90 of the fixed housing 10; and a fixed terminal pin 20, one end of which passes through the fixed insulator 30 and contacts the first panel B1 side, and the other end of which is electrically connected to the movable terminal pin 20' of the movable module M described later.

[0079] The fixed housing 10 can be made of a conductive material, or it can be configured such that the inner peripheral surface of the matching space 90 is plated with a conductive material, thereby facilitating the characteristic impedance matching design within the matching space 90.

[0080] The inner circumferential surface of the fixed outer shell 10 can have multiple stepped shapes with different inner diameters.

[0081] More specifically, a fixing anti-resonance rib 12 can be formed in the mating space 90 of the fixed housing 10 near the first panel B1 side, so that one end of the fixing insulator 30 and the elastic member 60 is separated and locked and supported. In addition, in the mating space 90 of the fixed housing 10 near the second panel B2 side, a one-sided locking part 14 and a other-sided locking part 16 can be formed in a stepped manner to limit the movable distance (hereinafter referred to as "movement range") of the outer conductor part 40' in the moving module M described later. Furthermore, a stop step 13 can also be formed on the inner peripheral surface of the fixed housing 10 to limit the movement of the front end 43' of the outer conductor guide 42' of the outer conductor part 40' described later.

[0082] Furthermore, a plurality of solder feet 11 may be integrally formed at one end of the fixed housing 10 (i.e., the portion corresponding to the side of the first panel B1). The plurality of solder feet 11 can be joined by welding after being inserted into solder holes (not shown in the figures) pre-formed on the side of the first panel B1. In this case, the fixing pin portion 21 of the fixing terminal pin 20 described later can also be inserted into the hole (not shown in the figures) of the contact portion pre-formed on the side of the first panel B1 and joined by welding.

[0083] The fixed terminal pin 20 is made of conductive material and can be electrically connected to the movable terminal pin 20'.

[0084] More specifically, the fixed terminal pin 20 may include: a fixed pin portion 21 extending from the mating space 90 side toward the first panel B1 side and protruding outward; a pin body portion 23 with a diameter larger than that of the fixed pin portion 21; and a hollow pin portion 25 extending from the pin body portion 23 toward the second panel B2 side, having a hollow (not shown in the figures) formed inside for inserting a portion of the movable pin portion 21' of the movable terminal pin 20' described later.

[0085] A locking shoulder 22 is formed at the boundary between the fixing pin 21 and the pin body 23 due to the difference in diameter. The locking shoulder 22 is locked to the fixing insulator 30, thereby preventing the fixing housing 10 from falling off to the outside.

[0086] The hollow pin portion 25 is hollow and opens towards the direction where the movable terminal pin 20' is provided. A plurality of hollow cut-out portions 26 can be cut into a portion of the outer peripheral surface of the hollow pin portion 25 to allow communication between the interior and the exterior. Through the plurality of hollow cut-out portions 26, additional tension is applied to the outer peripheral surface and a predetermined side surface of the movable pin portion 21' of the movable terminal pin 20' inserted into the hollow interior, thereby preventing the electrical signal connection between the fixed terminal pin 20 and the movable terminal pin 20' from being disconnected in advance.

[0087] On the other hand, the fixed insulator 30 is made of insulating material or dielectric material having a specified dielectric constant, and performs the function of insulating the fixed terminal pin 20 from the fixed housing 10, while also performing the function of fixing the fixed terminal pin 20 to the fixed housing 10.

[0088] That is, a through hole 32 for fixing part is formed in the middle of the fixing insulator 30, which extends vertically toward the first panel B1 and the second panel B2. The fixing pin part 21 in the structure of fixing terminal pin 20 is completely penetrated through the through hole 32 for fixing part, and a part of it can be exposed outside the fixing housing 10.

[0089] The fixing pin 21 exposed outside the fixed housing 10 can be welded to the contact portion (not shown) formed on the first panel B1 by welding. In addition, the other end edge 31 corresponding to the first panel B1 side of the fixed insulator 30 is locked by the fixing anti-resonance rib 12 formed on the inner peripheral surface of the fixed housing 10 and is separated and fixed so as not to contact the elastic member 60 described later.

[0090] The anti-resonance rib 12 of the fixing part formed on the inner peripheral surface of the fixing housing 10 performs the function of preventing resonance from occurring inside the matching space 90 by preventing the elastic member 60 from directly contacting the fixing insulator 20, which will be described in detail later.

[0091] On the other hand, such as Figure 4As shown, the moving module M may include: a moving terminal pin 20' made of conductive material, one end of which contacts the second panel B2, and the other end of which establishes an electrical signal line between the moving module M and the first panel B1 via a fixing module F; a moving insulator 30' having a specified dielectric constant, disposed in a manner that surrounds a portion of the outer peripheral surface of the moving terminal pin 20', and configured on the matching space 90 to achieve the characteristic impedance matching design value; and an outer conductor portion 40' disposed between the moving insulator 30' and the inner peripheral surface of the fixing housing 10, configured such that the elastic member 60 does not directly contact at least one of the moving insulator 30' and the moving terminal pin 20', for transmitting the elastic support force of the elastic member 60 to the moving insulator 30'.

[0092] like Figure 4 As shown, the movable terminal pin 20' may include: a movable pin portion 21' extending a predetermined length from the second panel B2 side to the first panel B1 side, with a portion of one end inserted into the hollow interior of the hollow pin portion 25 of the fixed terminal pin 20; and a movable contact portion 22' formed at the other end of the movable pin portion 21', with a middle portion cut in a groove shape to increase the contact rate with the contact portion (not shown) of the second panel B2.

[0093] This movable terminal pin 20' can perform the following functions: receive electrical signals transmitted from the first panel B1 side through the fixed terminal pin 20 and transmit them to the second panel B2 side, or transmit electrical signals transmitted from the second panel B2 side to the first panel B1 side through the fixed terminal pin 20.

[0094] Unlike the fixed terminal pin 20, the movable terminal pin 20' is configured to move within and outside the mating space 90 of the fixed housing 10 within a specified movement range, thereby establishing the aforementioned electrical signal lines while absorbing the assembly tolerances present between the first panel B1 and the second panel B2.

[0095] In addition, even when the moving section moves, the moving terminal pin 20' maintains the characteristic impedance matching design value in the matching space 90 by the moving insulator 30' which is arranged in such a way as to surround part of its outer peripheral surface.

[0096] More in detail, such as Figure 4 As shown, the movable insulator 30' can be configured as part of the outer peripheral surface of the movable pin portion 21' in the movable terminal pin 20'. The movable contact portion 22' in the movable terminal pin 20' structure is configured to have an outer diameter larger than the outer diameter of the movable pin portion 21'. A movable pin locking portion 23' is formed in a stepped manner at the boundary between the movable pin portion 21' and the movable contact portion 22'. The movable insulator 30' can move together with the movable terminal pin 20' and move within the moving range through the pressing force of the second panel B2.

[0097] In addition, a locking edge end 31' with a larger outer diameter is formed on the outer edge end of the second panel B2 side of the movable insulator 30' in a stepped manner, and it is also locked to the outer conductor portion 40' described later. Therefore, it can move together with the movable terminal pin 20' and the outer conductor portion 40' within the moving range by the tightness of the second panel B2.

[0098] A movable through hole 32' is formed in the middle part of this movable insulator 30', so that the movable pin part 21' in the movable terminal pin 20' structure is fully through, and the movable pin locking part 23', which is the boundary part between the movable contact part 22' with an outer diameter larger than the outer diameter of the movable pin part 21', can be locked at any position inside the movable through hole 32'.

[0099] The movable insulator 30' can be designed and configured such that its shape and dielectric constant maintain the characteristic impedance design value within the matching space 90 of the fixed housing 10. Furthermore, the movable insulator 30' is preferably designed to prevent characteristic impedance mismatch within the matching space 90 even when the movable terminal pin 20' moves within the moving range due to the clamping force of the second panel B2 during assembly.

[0100] On the other hand, such as Figure 4 As shown, the outer conductor portion 40' may include: an outer conductor body 41', configured to surround the outer peripheral surface of the movable insulator 30'; and an outer conductor guide 42', configured to extend from the outer conductor body 41' toward the first panel B1 side, and slide to the inner peripheral surface of the fixed housing 10 when the outer conductor body 41' moves.

[0101] A portion of the outer peripheral surface of the outer conductor body 41' is formed to have an outer diameter between a one-side locking portion 14 and a other-side locking portion 16 that are locked in the inner peripheral surface of the second panel B2 near the fixed housing 10. Thus, when moving within the movement range by the pressing force of the second panel B2, the movement range can be limited by being locked by the one-side locking portion 14 and the other-side locking portion 16 respectively.

[0102] That is, a portion of the outer peripheral surface of the outer conductor body 41' can be formed to have an outer diameter corresponding to the inner peripheral surface of the fixed housing 10, and an outer diameter corresponding to the outer diameter of the inner peripheral surface between the one-side locking portion 14 and the other-side locking portion 16. The length of the outer conductor body 41' with such an outer diameter is formed to be less than the distance between the one-side locking portion 14 and the other-side locking portion 16, so that the movement range of the moving module M can be limited to the range of the length difference.

[0103] Furthermore, the outer conductor body 41' can be integrally formed with the moving part anti-resonance rib 44', such that a portion of its inner circumferential surface has a smaller inner diameter than other parts. The moving part anti-resonance rib 44' supports the other end of the elastic member 60 (described later) while preventing the other end of the elastic member 60 from directly contacting and being supported by the moving insulator 30', thereby preventing resonance from occurring due to movement within the matching space 90.

[0104] On the other hand, the front end 43' of the outer conductor guide 42' can extend closer to the first panel B1 than the side locking portion 14.

[0105] Therefore, with the outer conductor body 41' fixed to the other side of the fixed housing 10 by the elastic support force of the elastic member 60 (described later), the front end 43' of the outer conductor guide 42' slides to the inner peripheral surface of the fixed housing 10 corresponding to the outer side of the one-sided locking part 14, thereby preventing malfunctions by preventing the locking phenomenon inside the fixed housing 10.

[0106] This outer conductor portion 40' can perform the function of stabilizing signal flow in the matching space 90 by functioning as a ground terminal together with the aforementioned second panel signal leakage shielding component 80.

[0107] In particular, the outer conductor portion 40', as a structure of the moving module M, is configured to move in conjunction with the moving terminal pin 20' and the moving insulator 30' that move within the moving range, and can also perform electrostatic shielding function together with the elastic member 60 described later, which is provided in direct contact.

[0108] The electrostatic shielding function of the outer conductor portion 40' and the elastic member 60 increases the design freedom of the placement of the elastic member 60, thereby providing the advantage of reducing the overall width dimension of the characteristic impedance mismatch prevention connector of the present invention.

[0109] More specifically, in traditional connectors (refer to...) Figure 1 In the case of [missing information], to prevent the elastic member 410 from directly contacting the fixed insulator 230 and the contact insulator 130, a space for accommodating the elastic member 410 is provided along the width direction without providing an outer conductor portion (reference numeral 40' of the present invention), and is configured to apply elastic force to the contact modules 110 and 120 relative to the fixed modules 210 and 220. Conversely, in the characteristic impedance mismatch prevention connector of the present invention, the outer conductor portion 40' prevents the elastic member 60 from directly contacting the fixed insulator 30 and the movable insulator 30', thereby significantly increasing the design freedom of the placement position within the matching space 90.

[0110] On the outer periphery of the fixed housing 10, near the second panel B2, a portion of the outer peripheral surface can be formed in a stepped manner to form a shielding member mounting end 15 on which the aforementioned cover signal leakage shielding member 70 is mounted. Additionally, the aforementioned second panel signal leakage shielding member 80 can be mounted on the front end face of the outer conductor portion 40' in the movable module M.

[0111] On the other hand, such as Figure 4 As shown, the moving module M moves within the moving range relative to the fixed module F which is fixed on the first panel B1 side, and can be elastically supported by the elastic force of the elastic member 60 provided in the matching space 90.

[0112] like Figure 4 As shown, one end of the elastic member 60 is supported by the aforementioned anti-resonance rib 12 of the fixed portion protruding inward from the fixed housing 10 so as not to contact the fixed insulator 30, and the other end can be supported by the anti-resonance rib 44' of the movable portion protruding inward from the outer conductor portion 40'.

[0113] In the structure of the outer conductor portion 40', the elastic member 60 is in a state of compression to a certain extent when the outer conductor body 41' is locked to the locking portion 16 on the other side of the fixed housing 10. When the second panel B2 applies a pressing force, the specified elastic force can be transmitted to the outer conductor portion 40' in the form of a reaction force while further compressing and deforming. The outer conductor portion 40', which receives the specified elastic force from the elastic member 50, moves the movable insulator 30' toward the second panel B2 and presses it against it. The movable contact portion 22' of the movable terminal pin 20', which moves in conjunction with the movable insulator 30', can maintain continuous contact with the contact portion of the second panel B2 through the specified elastic force.

[0114] In this case, as described above, it is very important that the elastic member 60 is configured to prevent direct contact with the fixed insulator 30 and the movable insulator 30' in order to prevent resonance from occurring in the matching space 90.

[0115] Therefore, as Figure 4 As shown, the elastic member 60 can be implemented as follows: a first embodiment in which the coil diameter is the largest at one end and the other end and gradually decreases towards the middle, as long as it does not directly contact the fixed insulator 30 and the movable insulator 30'.

[0116] In addition, such as Figure 5 and Figure 6 As shown, the elastic member 60 can also be in the form of having the same coil diameter.

[0117] For example, such as Figure 5As shown, the elastic member 60 can be implemented as a second embodiment, having the same coil diameter from one end to the other. As in the first embodiment, one end is supported to be physically separated from the fixed insulator 30 by the fixed anti-resonance rib 12, and the other end is physically separated from the movable insulator 30' by the movable anti-resonance rib 44'.

[0118] And, as Figure 6 As shown, the elastic member 60 can be implemented as a third embodiment as follows: it has the same coil diameter from one end to the other end, and like the first and second embodiments, one end is supported to be physically separated from the fixed insulator 30 by the anti-resonance rib 12 of the fixing part, and unlike the first and second embodiments, the other end is supported by the front end 43' of the outer conductor guide 42'.

[0119] Figure 7 To illustrate the frequency characteristics when the elastic member is supported in direct contact with the fixed insulator of the fixed module and the moving insulator of the moving module, a graph is shown. Figure 8 A graph illustrating the frequency characteristics of a connector for preventing characteristic impedance mismatch using an embodiment of the present invention.

[0120] Reference Figure 7 When the elastic component is supported to be in direct contact with the fixed insulator of the fixed module and / or the moving insulator of the moving module, it can be seen that resonance occurs at multiple points in the frequency band.

[0121] However, refer to Figure 8 When the elastic component 60 does not directly contact the fixed insulator 30 of the fixed module F and the movable insulator 30' of the movable module M, but performs the electrostatic shielding function together with the outer conductor part 40', it can be confirmed that no resonance phenomenon occurs in the frequency band.

[0122] According to an embodiment of the characteristic impedance mismatch prevention connector of the present invention configured as described above, when a signal is transmitted along the electrical signal line established between the first panel B1 and the second panel B2, mismatch within the matching space 90, which requires impedance matching design, can be prevented. Furthermore, the free design of the outer conductor portion 40' and the elastic member 60 can reduce the overall size of the product in the width direction, thus providing the manufacturing advantage of a connector with a simpler structure.

[0123] The present invention has been described in detail above with reference to the accompanying drawings, illustrating an embodiment of the connector for preventing characteristic impedance mismatch. However, the embodiments of the present invention are not necessarily limited to the above-described embodiments, and it is obvious that those skilled in the art can make various modifications and implement the invention within equivalent scope. Therefore, it can be said that the true scope of the present invention is determined by the appended claims.
