Description of the Invention: [Technical Field of the Invention] The present invention relates to a coaxial connector, and more specifically, a coaxial connector that is detachable from a socket. [Prior Art] As a conventional coaxial connector, a coaxial connector known in Patent Document 1 is known. So, for the coaxial connector - while referring to the schema - say. Fig. 9 is a cross-sectional structural view of the coaxial connector ι〇ι described in Patent Document i. Figure 10 is a cross-sectional view of the front end portion of the coaxial connector 101. In Fig. 9 and Fig. 10, the direction in which the probe 11 is protruded is the up and down direction. The coaxial connector 101 is provided at a distal end of a coaxial cable (not shown) as shown in Fig. 9, and includes a probe 11A, a coil spring 122, a casing 125, and a sleeve 130. The probe 110 extends in the up and down direction and is connected to the center conductor of the coaxial cable. The housing 125 is provided with a cylindrical front end portion 126a and is connected to a shield conductor of a coaxial cable (not shown). Furthermore, the clamshell 125 has grooves 127 & 127b. Further, the probe 110 is inserted into the distal end portion 126a. The sleeve 130 includes a lower portion 131 and an upper portion 135, and is a housing in which the coil spring 122 and the housing 125 are housed. The lower portion 131 includes a cylindrical portion iMa, a crotch portion 131b, a locking piece 132a, and a protruding portion 132b. The casing 125 is inserted into the cylindrical portion 131a. The end portion of the crotch portion 131b on the upper side of the cylindrical portion U1a is provided to be expanded in a direction perpendicular to the vertical direction (that is, in the horizontal direction), and the upper portion of the upper portion 135 is riveted to the upper portion. 135 is fixed. Further, the locking piece l32a is engaged with the projection i27a of the housing 125 at the projection 201006068 132b provided at the front end of the locking piece 132a. The upper portion 135 has a cylindrical shape with a lower opening, and accommodates a coil spring 122 and a casing 125 therein. The sleeve 130 and the housing 125 are slidable relative to each other along the side of the upper portion 135 in the up and down direction. However, generally, as shown in Fig. 9(a), the casing 125 is pressed by the coil spring 122 to the lower side to contact the lower portion 131. Thereby, the front end portion 126a of the casing 125 protrudes to the outside of the cylindrical portion 13 1 a. The coaxial connector 1〇1 having the above configuration is mounted on the counterpart socket 201 as shown in Fig. 1A. The counterpart socket 201 is, for example, a coaxial connector having a switch provided between the antenna of the mobile phone and the transceiver circuit, and includes a casing 203, an outer conductor 205, a fixed terminal 2〇6, and a movable terminal 2〇7. The fixed terminal 206 is connected to the antenna, and the movable terminal 2〇7 is connected to the transceiver circuit. Further, as shown in Fig. 1(4), since the fixed terminal 2〇6 is in contact with the movable terminal 207, the antenna is connected to the transceiver circuit. On the other hand, when the manufacturer tests the electrical characteristics of the transceiver circuit of the mobile phone, as shown in Fig. 10 (4), the probe 11 connected to the tester is inserted into the hole 204 of the casing 203 from the upper side to the lower side. Thereby, the movable terminal 207 is pushed downward by the probe U0. The result 'fixed end? 2〇6 is separated from the movable terminal 2〇7, and the probe 110 and the movable terminal 207 are connected, and the transceiver circuit is connected to the tester. Here, the details of the mounting of the coaxial connector 101 to the other receiving socket 2〇1 will be described. As shown in Fig. H) (4), at the front end of the end portion of the coaxial connector ι〇, a projection (four) projecting in the center direction of the front portion 26a is provided. Thereby, the inner diameter of the front end portion 126a is smaller than the outer diameter of the outer conductor 2〇5. However, the front end portion 126a has a configuration in which the diameter is retractable. Therefore, in the process of mounting the coaxial connector 101 to the other receiving socket 201, the outer conductor 205 is inserted into the inside of the front end portion 126a to make the front end portion 126a as shown in Fig. i(b). The state of 10(a) is more expanded. After the coaxial connector 101 is further pushed downward, as shown in the figure, the projection 126b is engaged with the groove 205a' formed on the outer circumference of the outer conductor 205 and the front end portion 126a contacts the upper surface 205b of the outer conductor 205. After the reaction force generated by the upper side 2〇5b against the front end portion l26a is greater than the force required to start the contraction of the coil spring 122 due to the force of the sleeve 130 being pushed downward, the coil spring 122 is contracted 'the sleeve 130 is opposite Slide the shell 醴 125 to the lower side. The front end portion 126a is housed in the cylindrical portion 13 j a of the lower portion 131. The inner circumferential surface of the cylindrical portion 131a is pressed against the outer circumferential surface of the distal end portion 126a, and the projection 126b is firmly engaged with the groove 205a. Further, the inner peripheral surface of the cylindrical portion 13u is pressed against the outer peripheral surface of the distal end portion 126a, thereby preventing the distal end portion 126a from being plastically deformed due to excessive expansion of the distal end portion 126a. The coaxial connector 101 has a problem in durability as described below. More specifically, when the coaxial connector 1〇1 is mounted on the counterpart socket 2〇1, as shown in Fig. 9(b), the sleeve 130 slides downward with respect to the casing 125. At this time, since the coil spring 122 is more contracted than the state of Fig. 9(a), the casing 125 is pressed from the coil spring 122 to the lower side. As a result, due to the force of the coil spring 122, the coaxial connector is liable to fall off from the other socket 201. In the coaxial connector 丨〇1, the projection 132b provided at the front end of the locking piece 132a is engaged with the groove 127b provided in the casing 125 to maintain the state of Fig. 9(b). By the force of the coil spring 122 in the state in which the coaxial connector is mounted on the counterpart socket 2〇1 201006068, the suction collar connector 101 is prevented from returning from the state of FIG. 9(b) to FIG. 9 ( a) status. However, in the coaxial connector 101, as shown in Fig. 9, the mesh V does not, and if the sleeve 130 slides in the up and down direction with respect to the casing 125, the projection 13 is slid on the side surface of the casing 125. If the coaxial connector 1〇1 is detachably attached to the other receiving seat 2〇1, the casing 125 and the projection 132b are scraped to generate scraping. If such a scraper enters between the housing 125 and the projection 132b, the sleeve 13 cannot slide smoothly. As described above, the coaxial connector 1〇1 is a problem of durability. [Patent Document 1: International Publication No. 2007/080663] SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a coaxial connector excellent in durability. The coaxial connector of the present invention is detachably attachable to a counterpart socket having an outer conductor, and is characterized in that: a housing having a cylindrical front end portion inserted into the outer conductor, and the front end portion The traverse 2 has a retractable structure; the probe extends in the front end portion in a state insulated from the housing, the sleeve has a cylindrical portion into which the housing is inserted; and the elastic body ' is not mounted When the other seat is seated, a force is generated on the casing and the sleeve to keep the front magnet portion protruding to the outside of the cylindrical portion, and the housing and the housing are The sleeve is energized such that at least a portion of the front end portion is received in the tubular portion ' and the front end portion contacts the inner circumferential surface of the cylindrical portion to maintain 7 201006068. Expansion is limited to the second shape. The present invention has the advantage that the durability can be obtained: the same as the "embodiment" (the structure of the coaxial connector).

The magnets 27 and 23 are as shown in Figs. 1 and 2, and have an opening shape and are mounted on the upper portion. 35, the opening is directed to the lower side. Therefore, the magnetic 7 is attached to the lower side of the consuming 23, and the surface facing the lower side of the sister η is opposed to the disk 21 and opposed to each other. Therefore, the magnet 27 series and the disk 21 spiral yellow 22 are arranged on the upper side of the disk 21. The more detailed:: one end of the coil spring 22 contacts the upper side of the disk 2, and the spiral The other end of the sauce 22 is in contact with the lower side facing the lower side. By 201006068, when the coil spring 22 is shortened from the natural length, the casing μ is pushed out to the lower side by the force of the coil spring 22. Therefore, the front end portion 26& protrudes to the outside of the cylindrical portion 31a of the lower portion 31. In addition, an elastic body such as rubber may be used instead of the spiral bomb. 22.

The upper part of 35. (Operation of the coaxial connector) ° Next, the operation of the coaxial connector 1 will be described with reference to Fig. 7 and Fig. 8. Fig. 7 is before the installation of the other seat 2〇1, during the installation process, And the coaxial connector after installation! The cross-sectional construction of the front end section. The picture shows the coaxial connector i before and after the installation of the seat. Fu
首先，針對同轴連接器i在裝設於對方承接座2〇ι ^ 之狀態（以下，稱為第！狀態）說明。如圖8(a)所示，圓盤2 係被螺旋彈簧22推壓至下側。藉此，殼體25被螺旋彈夸 22推壓至下側，上部25a之朝向下側之下面…接觸鍔奇 31b之朝向上側之面。藉此，殼體乃相對於套筒％被定位 前端部26a則從殼體25之筒狀部31a突出既定長度。 此外，第1狀態中，圓盤21、螺旋彈菁22、磁石27First, the state in which the coaxial connector i is mounted on the other socket 2 (hereinafter referred to as the "!" state) will be described. As shown in Fig. 8(a), the disk 2 is pressed by the coil spring 22 to the lower side. Thereby, the casing 25 is pushed to the lower side by the spiral bobbin 22, and the lower surface of the upper portion 25a facing the lower side ... contacts the upper side facing the side 31b. Thereby, the casing is positioned with respect to the sleeve %, and the front end portion 26a protrudes from the cylindrical portion 31a of the casing 25 by a predetermined length. Further, in the first state, the disk 21, the auger 22, and the magnet 27
及軛23係被選擇為使螺旋彈簧22對殼體乃及套筒川所 產生之力大於磁石27對殼體25及套筒3〇所產生之力。藉 此，同軸連接器1在未裝設於對方承接座2〇1時，前端部 26a突出至筒狀部31a之外部之狀態，係藉由螺旋彈簧22 來保持。 其次，針對同軸連接器1被裝設於對方承接座2〇1之 過程說明。同軸連接器1之往對方承接座2〇1之裝設，係 藉由握住上部35再向下推壓該上部35來進行。如圖7(a) 所示，於同轴連接器1之前端部26a的前端，設有往該前端 12The yoke 23 is selected such that the force generated by the coil spring 22 against the housing and the sleeve is greater than the force generated by the magnet 27 against the housing 25 and the sleeve 3. Therefore, when the coaxial connector 1 is not attached to the counterpart socket 2〇1, the distal end portion 26a protrudes to the outside of the tubular portion 31a, and is held by the coil spring 22. Next, a description will be given of a process in which the coaxial connector 1 is mounted to the counterpart socket 2〇1. The mounting of the coaxial connector 1 to the other receiving socket 2〇1 is performed by holding the upper portion 35 and pushing the upper portion 35 downward. As shown in Fig. 7(a), the front end of the front end portion 26a of the coaxial connector 1 is provided to the front end 12
❷ 201006068 部26a之中心方向突出的突部26b。因此，前端部26a之内 徑係較外部導鱧205之外徑小。然而，前端部26a具有其内 裎為可伸縮之構造。因此，在同轴連接器1之往於對方承 接座201之裝設之過程中，藉由將外部導體2〇5插入前端 6a之内部，如圖7(b)所示，前端部26a之内徑即較圖 7(a)所示之第丨狀態更為擴張。 在同軸連接器1被進一歩向下側推壓後，如圖7(幻所 示，柱塞11之前端將可動端子2〇7向下側推壓。藉此，固 定端子206與可動端子207便分離。其結果，可動端子2〇7 即透過柱塞U、螺旋彈簧12、及筒13與同軸纜線4〇之中 心導體41成為導通狀態。 又，在圖7(c)之狀態下，突部26b係卡合於形成在外部 導體205外周之槽205a，且前端部26a係接觸外部導體2〇5 之上面205b。在因套筒30被向下侧推壓之力而使上面2〇讣 對前端部26a所產生之反作用力較螺旋彈簧22開始收縮所 須之力大後，螺旋彈簧22收縮，而套筒3()相對於殼體乃 往下側滑動。藉此，前端部26a即收納於下部η之筒狀部 31a内，筒狀部31a之内周面廢接於前端部26&之外周面， 藉此突部26b即堅固地卡合於槽咖。進—步藉由筒狀 部31a之㈣面壓接於前端部26a之外周面，防止因前端部 26a之内徑過度擴張而造成前端部26a塑性變形。由以上之 動作，同轴連接器！成為裝設於對方承接座2〇ι之狀態(以 下，稱為第2狀態）。 此外， 8(b)所示之第2狀態之同轴連接器 1中，由 13 201006068 於螺旋彈簧22係較圖8(a)所示之第1狀態呈更收縮之狀 態’因此殼體25係從螺旋彈簧22承受力，而被往下側推 壓。其結果，會因螺旋彈簧22之力而有同轴連接器i容易 從對方承接座201脫落之虞。 針對此問題，同轴連接器1中設有圓盤21、螺旋彈菁 22、磁石27、及軛23，以保持圖8(b)所示之第2狀態。更 詳言之’圖7(c)所示之第2狀態中，套筒30係滑動至較圖 7(a)所示之第1狀態更下侧。因此，螺旋彈簧22係呈收縮 之狀態，且軛23之下側之端部係接觸圓盤21。軛23之下 ◎ 側之端部接觸圓盤21 ’使第2狀態之殼體25與套筒30被 正確定位。又，由於圓盤21及軛23係由磁性材料所構成， 因此會因磁石27之磁力而彼此互相吸附。此處，在第2狀 態下，圓盤21、磁石27、及扼23被選擇為使磁石27對殼 體25及套筒3〇所產生之力大於螺旋彈簧22對殼體25及 套筒30所產生之力。其結果，在同軸連接器丨裝設於對方 承接座201時，前端部26a收納於筒狀部31a内，且因前端 部26a接觸筒狀部3la之内周面所造成之前端部26a之徑擴 〇 張受到限制的狀態，係藉由磁石2 7保持。 其次’在使同轴連接器1從對方承接座2〇1脫離時， 藉由與上述相反之步驟，亦即以手指握住上部35之外周部 再往上側拉開即可。在將上部35往上拉之力與螺旋彈簧22 欲伸張之力的合力較磁石27所產生之力大後，套筒3〇即 往上側移動，解除圓盤21與軛23之接觸。藉此，由於磁 石27對圓盤21之吸附力變弱，因此螺旋彈簧22所產生之 14 201006068 力即較磁石27所產生之力大。因此，下部31之鍔部31b 便藉由螺旋彈簧22往上側移動，且往上側移動至抵接殼體 25之下面25c為止。此時，由於前端部26a係突出至筒狀 部31a之外部，因此前端部26a與筒狀部3ia之接觸被解除 且該前端部26a之徑擴張。藉此’突部2讣即從槽2〇5&脫 離接著，對方承接座201中，可動端子2〇7即因本身之 彈性而往上側位移，回歸至與固定端子2〇6之連接狀態。 其次，針對將外部導體205插入前端部26a所須之力 F1、在圖8(a)之狀態下使螺旋彈簧22收縮所須之力ρ2、在 圖8(b)之狀態下螺旋彈簧22所產生之力ρ3、及在圖_ 之狀態下磁石27所產生之力F4的關係說明。 首先，在將同軸連接器丨裝設於對方承接座2〇1時， 使用者必須以力上之力將套筒3〇往下側推麼。藉此， 將外部導體2G5插人前端部26a。此外，力F2之大小係必 須較力Fih當力F2u小較力F1小時，在將外部導體 205插入前端部26a之前，螺旋彈簧22即收縮而套筒川往 下側滑動。此時’即無法將同轴連接_ i裝設於對方承接 座201。在此’本案發明人係將同轴連接器i料成力η 之大小為4Ν ’力F2之大小為5Ν。 在外部導體205插人前端部％後，使用者即以力以 以上之力將套筒30往下側推壓。藉此，螺旋彈簧Μ即收 縮而前端部26a便收納於筒狀部318内，同轴連接器i即被 裝設於對方承接座201。 另-方面’將同轴連接器i從對方承接座2〇1稅離時， 15 201006068 使用者必須以較力F4與力F3之差更大之力將套筒30往上 拉。藉此’螺旋彈簧22所產生之力F3與使用者之力的合 力即較磁石27所產生之力F4大，圓盤21與軛23分離。 於是，同轴連接器1即從對方承接座2〇1脫離。本案發明 人係將力F3之大小設計成7N，並將力F4之大小設計成 9N。藉此’使用者可藉由施加2N以上之力，使同軸連接器 1從對方承接座201脫離。 (效果） 根據以上述方式所構成之同轴連接器1，如以下說明 ❹ 般，相較於同轴連接器101，可獲得較高耐久性。更詳言之， 同轴連接器101中’如圖9所示，由於突部132b係相對於 殼體125滑動，因此若重複同轴連接器ι〇1之往對方承接 座201之反覆裝設’突部132b或殼體125便會受到刮削而 產生刮屑。此種碎屑會進入突部132b與殼體ι25之間，而 阻礙套筒13〇之順利滑動。 再者’若突部132b相對於殼體125滑動，突部132b 及槽127a，i27b會受到刮削。因此，突部U2b與槽ι27& φ 127b便無法堅固地卡合。如以上所述，同軸連接器1〇1有 耐久性之問題。 另—方面，同轴連接器1中，如圖8(b)所示，係藉由 磁石27將殼體25拉升至上側，以保持叢設有對方承接座 201之第2狀態。因此，在同轴連接器對對方承接座 2〇1之裝卸時，由於殼體25與套筒30幾乎不滑動因此殼 體25與套筒3〇之間不會產生刮屑。因此，即使同轴連接 16 201006068 器1被反覆對對方承接座201裝卸，亦不會阻礙套筒3〇之 順利滑動。根據以上所述，相較於同轴連接器丨〇丨，利用同 軸連接器1可獲得較高之耐久性。 此外’本發明人製作同轴連接器1，101，並進行該同軸 連接器1，101之耐久測試。習知同轴連接器1〇1，在突部 132b與殼韹125之間塗布蠟時，在10000次程度之裝卸會 產生不良’在突部132b與殼體125之間不塗布蠟時，在300 次左右之裝卸即產生不良。另一方面，同軸連接器1已確 認可耐受20000次以上對對方承接座2〇1之裝卸。根據以 上’藉由封久測試，可知同轴連接器1相較於同轴連接器 1〇1具有較高之耐久性。 又’同軸連接器101中，於突部132b與殼體125之間 必須塗布蝶’以提升耐久性。然而，同轴連接器1中，在 殼體25與套筒30受到推壓之狀態下並不滑動，因此不需 又，同抽連接器1中，如圖8(b)所示，在裝設於對方 承接座201之第2狀態’圓盤21與軛23接觸，而圓盤21 與磁石27則未接觸。藉此，如以下說明般，殼體25與套 筒30即穩定吸附。 更詳言之，圓盤21及軛23係由強磁性體材料所構成。 因此，如圖8(b)所示，若圓盤21與軛23接觸，便會產生 如箭頭0所示之磁通。此時，在磁石27接觸圓盤21時， 圓盤21與輥23係最強吸附。因此，較佳為圓盤21與輛23 接觸’且圓盤21與磁石27亦接觸。另一方面，若圓盤21 17 201006068 與辆23未接觸’圓盤21與軛23間之吸附力相較於圓盤21 與輛23接觸時之吸附力係極小。即使於磁石27與圓盤21 之間有間隙’只要圓盤21與軛23有接觸，吸附力僅微幅 降低，且該吸附力為穩定。 實際之產品中，磁石27係透過接著劑固定於軛23,該 接著劑厚度之偏差會造成磁石27之下面之位置產生偏差。 又，經燒成之磁石27之面精度不佳，該精度亦會造成磁石 27之下面之位置產生偏差。如上述，因製造偏差等而難以 製造成使圓盤21與軛23接觸，且圓盤21與磁石27接觸 之狀態。因此，考量接著劑之偏差、及磁石27之面精度， 而於磁石27之下面與圓盤21之間設置微幅之間隙，並設 定圓盤、軛23、及磁石27之尺寸，以使圓盤21與輛23 完全地接觸。磁石27係進行高精度之研磨加工以降低其偏 差。藉由於磁石27與圓盤21之間設置間隙，則亦無須進 行高精度之研磨加工。 又’同轴連接器i中’磁石27係設置成位於螺旋彈菁 22内。因此，同軸連接器i相較於將磁石設置於螺旋彈簧 外之同軸連接器可謀求小型化。 (其他實施形態） 此外，同轴連接器並不限於^ 哏於上述實施形態之同軸連接 器1，在其要旨之範圍内可作各種變更。 同軸連接器1中，雖將輕 並將圓盤21安裝於殼體25， 之安裝位置並不限於此。例如 23與磁石27安裝於套筒3〇, 但魏23、磁石27 '及圓盤21 ’亦可將軛23與磁石27安 201006068 裝於殼體25’而將圓盤21安裝认太& 诹遞 文裝於套筒30。然而，由於將❷ 201006068 The protrusion 26b protruding in the center direction of the portion 26a. Therefore, the inner diameter of the front end portion 26a is smaller than the outer diameter of the outer guide 205. However, the front end portion 26a has a configuration in which the inner bore is retractable. Therefore, in the process of attaching the coaxial connector 1 to the other socket 201, the outer conductor 2〇5 is inserted into the front end 6a, as shown in Fig. 7(b), inside the front end portion 26a. The diameter is more expanded than the third state shown in Figure 7(a). After the coaxial connector 1 is pushed into the lower side, as shown in Fig. 7 (the magic end, the front end of the plunger 11 pushes the movable terminal 2〇7 to the lower side. Thereby, the fixed terminal 206 and the movable terminal 207 As a result, the movable terminal 2〇7, that is, the plunger U, the coil spring 12, and the tube 13 are electrically connected to the center conductor 41 of the coaxial cable 4〇. Further, in the state of Fig. 7(c), The projection 26b is engaged with the groove 205a formed on the outer circumference of the outer conductor 205, and the front end portion 26a contacts the upper surface 205b of the outer conductor 2〇5. The upper surface is pressed by the force of the sleeve 30 being pressed downward. When the reaction force generated by the front end portion 26a is larger than the force required to start the contraction of the coil spring 22, the coil spring 22 contracts, and the sleeve 3 () slides downward with respect to the casing. Thereby, the front end portion 26a That is, it is housed in the cylindrical portion 31a of the lower portion η, and the inner peripheral surface of the tubular portion 31a is detached from the outer peripheral surface of the front end portion 26 & 26, whereby the projection 26b is firmly engaged with the slot. The (four) surface of the tubular portion 31a is pressed against the outer peripheral surface of the front end portion 26a to prevent the front end portion 26a from being excessively expanded due to the excessive inner diameter of the front end portion 26a. Plastic deformation. In the above operation, the coaxial connector is mounted in the state of the other seat 2 (hereinafter referred to as the second state). In addition, the second state shown in 8 (b) is coaxial. In the connector 1, the coil spring 22 is in a state of being more contracted than the first state shown in Fig. 8(a) by 13 201006068. Therefore, the casing 25 is pressed from the coil spring 22 and pushed to the lower side. As a result, the coaxial connector i is easily detached from the counterpart socket 201 due to the force of the coil spring 22. In response to this problem, the coaxial connector 1 is provided with a disk 21, a helical elastic 22, and a magnet. 27, and the yoke 23, in order to maintain the second state shown in Figure 8 (b). More specifically in the second state shown in Figure 7 (c), the sleeve 30 is slid to be compared to Figure 7 (a) The first state shown is lower. Therefore, the coil spring 22 is in a contracted state, and the end portion on the lower side of the yoke 23 contacts the disk 21. The end portion of the yoke 23 is in contact with the disk 21' The casing 25 and the sleeve 30 in the second state are correctly positioned. Further, since the disk 21 and the yoke 23 are made of a magnetic material, they are mutually mutually affected by the magnetic force of the magnet 27 Here, in the second state, the disk 21, the magnet 27, and the weir 23 are selected such that the force generated by the magnet 27 against the casing 25 and the sleeve 3 is greater than the coil spring 22 to the casing 25 and the sleeve. The force generated by the cylinder 30. As a result, when the coaxial connector is attached to the other socket 201, the distal end portion 26a is housed in the tubular portion 31a, and the distal end portion 26a contacts the inner circumferential surface of the tubular portion 31a. The state in which the expansion of the front end portion 26a is restricted is maintained by the magnet 27. Next, when the coaxial connector 1 is detached from the counterpart socket 2〇1, by the reverse steps described above, That is, the outer peripheral portion of the upper portion 35 is held by fingers and pulled upward. When the resultant force of pulling the upper portion 35 upward and the force of the coil spring 22 to be stretched is larger than the force generated by the magnet 27, the sleeve 3 is moved upward to release the contact between the disk 21 and the yoke 23. Thereby, since the adsorption force of the magnet 27 on the disk 21 is weakened, the force of the 14 201006068 generated by the coil spring 22 is larger than that generated by the magnet 27. Therefore, the crotch portion 31b of the lower portion 31 is moved upward by the coil spring 22, and is moved upward to abut against the lower surface 25c of the casing 25. At this time, since the distal end portion 26a protrudes to the outside of the tubular portion 31a, the contact between the distal end portion 26a and the tubular portion 3ia is released, and the diameter of the distal end portion 26a is expanded. Then, the projection 2 is disengaged from the groove 2〇5& and the movable terminal 2〇7 is displaced upward by the elasticity of the other end socket 201, and returns to the connection state with the fixed terminal 2〇6. Next, the force F1 required to insert the outer conductor 205 into the front end portion 26a, the force ρ2 required to contract the coil spring 22 in the state of Fig. 8(a), and the coil spring 22 in the state of Fig. 8(b) The relationship between the generated force ρ3 and the force F4 generated by the magnet 27 in the state of Fig. _ is explained. First, when the coaxial connector is mounted on the other socket 2〇1, the user must push the sleeve 3 to the lower side with a force. Thereby, the outer conductor 2G5 is inserted into the front end portion 26a. Further, the force F2 must be smaller than the force Fih when the force F2u is small and the force F1 is small. Before the outer conductor 205 is inserted into the front end portion 26a, the coil spring 22 is contracted and the sleeve is swung downward. At this time, the coaxial connection_i cannot be mounted to the counterpart receptacle 201. Here, the inventor of the present invention has the size of the force η of the coaxial connector i being 4 Ν 'the force F2 is 5 Ν. After the outer conductor 205 is inserted into the front end portion %, the user pushes the sleeve 30 downward with a force of above. Thereby, the coil spring Μ is contracted, and the distal end portion 26a is housed in the tubular portion 318, and the coaxial connector i is attached to the counterpart socket 201. On the other hand, when the coaxial connector i is separated from the other seat 2, 1 201006068, the user must pull the sleeve 30 upward by a force greater than the difference between the force F4 and the force F3. Thereby, the resultant force of the force F3 generated by the 'coil spring 22' and the force of the user is larger than the force F4 generated by the magnet 27, and the disk 21 is separated from the yoke 23. Thus, the coaxial connector 1 is detached from the counterpart socket 2〇1. The inventor of the present invention designed the size of the force F3 to be 7N and the size of the force F4 to be 9N. Thereby, the user can detach the coaxial connector 1 from the counterpart socket 201 by applying a force of 2 N or more. (Effects) According to the coaxial connector 1 constructed as described above, as compared with the coaxial connector 101, higher durability can be obtained. More specifically, in the coaxial connector 101, as shown in FIG. 9, since the protrusion 132b slides relative to the housing 125, if the coaxial connector ι1 is repeated, the reverse mounting of the counterpart socket 201 is repeated. The projection 132b or the housing 125 is scraped to cause scraping. Such debris can enter between the projection 132b and the housing ι25, and hinders the smooth sliding of the sleeve 13. Further, if the projection 132b slides relative to the housing 125, the projection 132b and the grooves 127a, i27b are scraped. Therefore, the projection U2b and the groove ι27 & φ 127b cannot be firmly engaged. As described above, the coaxial connector 101 has a problem of durability. On the other hand, in the coaxial connector 1, as shown in Fig. 8(b), the casing 25 is pulled up to the upper side by the magnet 27 to maintain the second state in which the other side receiving seat 201 is bundled. Therefore, when the coaxial connector is attached to and detached from the counterpart socket 2〇1, since the casing 25 and the sleeve 30 hardly slide, no scraping is generated between the casing 25 and the sleeve 3〇. Therefore, even if the coaxial connection 16 201006068 is repeatedly loaded and unloaded to the other receiving socket 201, the smooth sliding of the sleeve 3 will not be hindered. According to the above, higher durability can be obtained by using the coaxial connector 1 as compared with the coaxial connector. Further, the inventors made the coaxial connector 1, 101 and conducted the endurance test of the coaxial connector 1, 101. In the conventional coaxial connector 1〇1, when wax is applied between the protrusion 132b and the case 125, a defect occurs in 10,000 times of loading and unloading. When the wax is not applied between the protrusion 132b and the case 125, About 300 times of loading and unloading caused bad. On the other hand, the coaxial connector 1 has been confirmed to withstand the loading and unloading of the counterpart socket 2〇1 for more than 20,000 times. According to the above test, it is known that the coaxial connector 1 has higher durability than the coaxial connector 1〇1. Further, in the coaxial connector 101, a butterfly ' must be applied between the projection 132b and the casing 125 to improve durability. However, in the coaxial connector 1, the casing 25 and the sleeve 30 are not slid in a state of being pressed, so that it is not necessary, and the same connector 1 is mounted as shown in Fig. 8(b). The disk 21 is in contact with the yoke 23 in the second state of the counterpart socket 201, and the disk 21 and the magnet 27 are not in contact. Thereby, as will be described below, the casing 25 and the sleeve 30 are stably adsorbed. More specifically, the disk 21 and the yoke 23 are composed of a ferromagnetic material. Therefore, as shown in Fig. 8(b), if the disk 21 comes into contact with the yoke 23, a magnetic flux as indicated by an arrow 0 is generated. At this time, when the magnet 27 contacts the disk 21, the disk 21 and the roller 23 are most strongly adsorbed. Therefore, it is preferable that the disk 21 is in contact with the vehicle 23 and the disk 21 is in contact with the magnet 27. On the other hand, if the disk 21 17 201006068 is not in contact with the vehicle 23, the adsorption force between the disk 21 and the yoke 23 is extremely small as compared with the case where the disk 21 is in contact with the vehicle 23. Even if there is a gap between the magnet 27 and the disk 21, as long as the disk 21 is in contact with the yoke 23, the adsorption force is only slightly lowered, and the adsorption force is stable. In the actual product, the magnet 27 is fixed to the yoke 23 through an adhesive, and the deviation of the thickness of the adhesive causes a deviation in the position below the magnet 27. Further, the accuracy of the surface of the fired magnet 27 is not good, and the accuracy also causes a deviation in the position below the magnet 27 . As described above, it is difficult to manufacture the disk 21 in contact with the yoke 23 due to manufacturing variations or the like, and the disk 21 is in contact with the magnet 27. Therefore, considering the deviation of the adhesive and the surface accuracy of the magnet 27, a slight gap is provided between the lower surface of the magnet 27 and the disk 21, and the dimensions of the disk, the yoke 23, and the magnet 27 are set so that the circle The disk 21 is in full contact with the vehicle 23. The magnet 27 series performs high-precision grinding to reduce the deviation. Since a gap is provided between the magnet 27 and the disk 21, it is not necessary to perform high-precision grinding. Further, the "coaxial connector i" magnet 27 is disposed so as to be located inside the spiral elastic crystal 22. Therefore, the coaxial connector i can be downsized compared to the coaxial connector in which the magnet is provided outside the coil spring. (Other Embodiments) The coaxial connector is not limited to the coaxial connector 1 of the above embodiment, and various modifications can be made without departing from the spirit and scope of the invention. In the coaxial connector 1, although the disk 21 is lightly attached to the casing 25, the mounting position is not limited thereto. For example, 23 and the magnet 27 are attached to the sleeve 3, but the Wei 23, the magnet 27' and the disk 21' can also be mounted on the housing 25' with the yoke 23 and the magnet 27A 201006068 to mount the disk 21. The 诹 message is mounted on the sleeve 30. However, due to
平板狀之圓盤21壓入殼體25較脾圓教& A 双將圓请狀之輛23壓入殼體 25簡單，因此較佳為將軛23與 ’石27女裝於套筒30，並 將圓盤21安裝於殼體25。 又’亦可設置磁石以取代圓盤21。 又，同轴連接器1中’螺旋彈簧22與磁石27雖較接 近設置，但此等亦可分離設置。Pressing the flat disc 21 into the housing 25 is easier than pressing the spleen round & A double into the housing 25, so it is preferable to yoke the yoke 23 and the 'stone 27' in the sleeve 30 And the disk 21 is mounted to the housing 25. Further, a magnet may be provided instead of the disk 21. Further, in the coaxial connector 1, the coil spring 22 and the magnet 27 are disposed close to each other, but these may be separately provided.

However, it is not necessarily completely accommodated in the tubular portion. When the diameter of the outer conductor 205 is large, the diameter of the front end 胄% may be greatly expanded, and the front end portion 26a may not be completely accommodated in the cylindrical portion 3U. Therefore, at least a part of the distal end portion 26a may be accommodated in the tubular portion 3U.
