Description
本案係有關一種電連接器，尤指一種具有密封功能之電連接器。尤有進者，本案進一步提供一種用於電連接器之密封圈。 The present invention relates to an electrical connector, and more particularly to an electrical connector having a sealing function. In particular, the present invention further provides a sealing ring for an electrical connector.
按電連接器於電器產品中多有所見，其主要用途在於電源或訊號的傳導，因此，電連接器已廣泛地用於資訊產品的連接，並為不可或缺的構件。 According to electrical connectors, there are many advantages in electrical products. The main purpose of electrical connectors is the transmission of power sources or signals. Therefore, electrical connectors have been widely used for the connection of information products and are indispensable components.
事實上，電連接器的運用不僅僅在於前述之電器產品，其亦廣泛用於汽機車之電路系統，以作為線路的連接。由於汽、機車必須在各種天候下行駛，以致車體內難免會有異物，例如液體及灰塵的進入。因此，若電連接器無密封結構的設置，則前述異物會進入電連接器內部，使其無法正常運作。 In fact, the use of electrical connectors is not only in the aforementioned electrical products, but also widely used in the circuit system of steam locomotives as a connection of lines. Since steam and locomotives must travel in various weathers, foreign objects such as liquids and dust are inevitably in the vehicle body. Therefore, if the electrical connector has no sealing structure, the foreign matter will enter the inside of the electrical connector, making it unable to operate normally.
即以汽、機車使用之電連接器為例，為形成密封效果，該電連接器係在殼體與套設之格柵件間設有一插塞件，該插塞件周緣突設至少一周向凸緣，該凸緣被設置成與殼體周向內表面密封地接合，使液體及灰塵等異物不致通過該插塞件，而進入電連接器內。該插塞件軸向開設複數個貫穿通道，各通道內具有環狀內唇緣，以便對通過通道之導線形成單獨密封。而該插塞件之周向凸緣與殼體周向內表面所形成之周向密封，亦即該周向凸緣被殼體內壁推擠後，往往使得通道變形，而令周向密封與單獨密封相互影響，而不利形成最佳的密封效果。 For example, in the case of an electric connector used in steam or locomotive, in order to form a sealing effect, the electrical connector is provided with a plug member between the housing and the sleeve member, and the peripheral edge of the plug member protrudes at least one week. A flange that is configured to sealingly engage the circumferential inner surface of the housing such that foreign matter such as liquids and dust does not pass through the plug member into the electrical connector. The plug member defines a plurality of through passages in the axial direction, and each of the passages has an annular inner lip to form a separate seal for the wires passing through the passage. The circumferential flange of the plug member is circumferentially sealed with the circumferential inner surface of the casing, that is, the circumferential flange is pushed by the inner wall of the casing, and the passage is often deformed, so that the circumferential seal is Separate sealing affects each other, which does not contribute to the best sealing effect.
基於前述缺失，例如中國專利公開第CN 101176239A(對應於WIPO國際公開第WO2006/108442號專利案)即揭露一種用於電連接器之環式(grommet)接頭，該接頭包括一插塞件，其周緣突設至少一周向凸緣，該凸緣由該插塞件後側向後軸向突出，以致該凸緣與電連接器殼體周向內表面的接觸區域沿著該軸向方向相對於後側具有至少部分地偏移。其中，該插塞件為一六面體，其 後側向後軸向突出之楔形凸緣被一套設於殼體後方開口之格柵件前方周向突設之斜面推擠下，使該凸緣變形，而形成與殼體周向內表面密封地接合。此舉固然可令周向密封與單獨密封不致相互影響，而具有較佳的密封效果。 Based on the aforementioned deficiencies, for example, Chinese Patent Publication No. CN 101176239A (corresponding to WIPO International Publication No. WO2006/108442) discloses a grommet connector for an electrical connector, the connector including a plug member. The peripheral edge protrudes at least one circumferential flange, the flange projecting axially rearward from the rear side of the plug member such that the contact area of the flange with the circumferential inner surface of the electrical connector housing is along the axial direction relative to the rear side Having at least partial offset. Wherein the plug member is a hexahedron, The wedge-shaped flange protruding axially from the rear side is pushed by a set of inclined surfaces which are arranged in the circumferential direction of the front of the grille opening at the rear of the casing to deform the flange to form a seal with the circumferential inner surface of the casing. Ground joint. This allows the circumferential seal and the separate seal to not interfere with each other, and has a better sealing effect.
惟前述專利案顯著缺失在於，因插塞件之凸緣較薄，而容易破損，且該凸緣必須經由格柵件推擠後產生變形，始有密封效果。因此，如何另闢蹊徑，進一步簡化該密封圈之密封結構，乃相關業者共同面臨之課題。 However, the above patent case has a significant disadvantage in that the flange of the plug member is easily damaged due to its thin flange, and the flange must be deformed after being pushed by the grill member to have a sealing effect. Therefore, how to find another way to further simplify the sealing structure of the sealing ring is a common problem faced by the relevant industry.

FIG. 5 is a perspective view of the second embodiment of the electrical connector of the present invention. FIG. 6a and FIG. 6b are two cross-sectional views of the second embodiment of the electrical connector of the present invention in which the grill member is unlocked and locked to the housing.
如圖1a至圖3b所示，基本上，本案之電連接器之第一實施例係由一殼體1，一密封圈2，及一格柵件3所組成。 As shown in FIGS. 1a to 3b, basically, the first embodiment of the electrical connector of the present invention is composed of a casing 1, a sealing ring 2, and a grating member 3.
其中，殼體1係由絕緣材料，例如塑膠所製成，其上段具有一接合部11，該接合部11下方一體連接尺寸較大之裙部12，該裙部12內部設有一容置空間121，以便供後敘密封圈2及格柵件 3之容置與鎖定。該接合部11用以供另一電連接器的對接，因此，該接合部11軸向開設複數個連通於容置空間121的端子槽13，其係供習知的端子14容置與定位後，各端子14之導線141由該密封圈2及格柵件3穿出。此外，該容置空間121頂部內壁突設一環形第一定位凸緣15，以便與密封圈2對應設置的凹槽相接合。 The housing 1 is made of an insulating material, such as a plastic material, and has an engaging portion 11 at an upper portion thereof. The skirt portion 12 is integrally connected to the lower portion 12, and an accommodating space 121 is disposed inside the skirt portion 12. For the purpose of the rear seal 2 and the grille 3 is placed and locked. The joint portion 11 is used for the mating of the other electrical connector. Therefore, the joint portion 11 axially opens a plurality of terminal slots 13 communicating with the accommodating space 121 for receiving and positioning the conventional terminal 14. The wire 141 of each terminal 14 is passed through the sealing ring 2 and the grill member 3. In addition, an annular first positioning flange 15 protrudes from the inner wall of the top of the accommodating space 121 so as to be engaged with the corresponding groove provided by the sealing ring 2.
為避免格柵件3由殼體1之裙部12底部口軸向脫出，故兩者間設有一鎖定機構，例如裙部12兩相對壁面開設扣槽16，而格柵件3兩相對外壁則突設具斜面之突出物31。當該對突出物31卡和於扣槽16內時，即形成如圖3b所示之鎖定關係。 In order to prevent the grill member 3 from being axially disengaged from the bottom opening of the skirt portion 12 of the housing 1, a locking mechanism is provided therebetween. For example, the opposite wall surfaces of the skirt portion 12 define a locking groove 16, and the grill member 3 has two opposite outer walls. Then, a beveled protrusion 31 is protruded. When the pair of protrusions 31 are caught in the buckle groove 16, a locking relationship as shown in Fig. 3b is formed.
密封圈2係以彈性材料所製成，其造形對應於該裙部12內部容置空間121橫截面造形，例如矩形。該密封圈2包括一插塞件21，其對應各端子槽13位置開設貫通之通孔22。如圖3所示，各通孔22內具有至少一對軸向間隔之環形內唇緣23，因此，各通孔22內因該對內唇緣23的存在，而界定出兩個可變形之狹窄部。所以，在使用時，各內唇緣23係與穿越通孔22的導線141密封接合，從而在前述之狹窄部形成導線141上的內部單獨密封。 The sealing ring 2 is made of an elastic material, and its shape corresponds to a cross-sectional shape of the inner housing space 121 of the skirt 12, such as a rectangular shape. The sealing ring 2 includes a plug member 21 that opens through the through hole 22 corresponding to the position of each of the terminal slots 13. As shown in FIG. 3, each of the through holes 22 has at least one pair of axially spaced annular inner lips 23, so that each of the through holes 22 defines two deformable stenuses due to the presence of the pair of inner lips 23. unit. Therefore, in use, each inner lip 23 is sealingly engaged with the wire 141 passing through the through hole 22, thereby being separately sealed inside the narrow portion forming wire 141.
該密封圈2技術特徵在於，其頂、底面外壁與通孔22間區域分別軸向開設一第一周向定位槽24及一第二周向定位槽25。該第一周向定位槽24係與裙部12容置空間121頂面內壁之第一定位凸緣15嵌插接合；而第二周向定位槽25則與該格柵件3頂面對應突設之第二定位凸緣32嵌插接合。因此，在外觀上，本案插塞件周向表面呈現平整狀態，而無周向凸緣的設置，從而降低損毀的機會。 The sealing ring 2 is characterized in that a first circumferential positioning groove 24 and a second circumferential positioning groove 25 are axially opened in a region between the top and bottom outer walls and the through hole 22, respectively. The first circumferential positioning groove 24 is engaged with the first positioning flange 15 of the inner wall of the top surface of the skirt 12 accommodating space 121; and the second circumferential positioning groove 25 corresponds to the top surface of the grating member 3 The protruding second positioning flange 32 is insert-engaged. Therefore, in appearance, the circumferential surface of the plug member of the present case is flat, without the arrangement of the circumferential flange, thereby reducing the chance of damage.
尤有進者，為使該插塞件21周向外壁能夠緊密地接合於容置空間12之周向內壁，因此，該第一、第二周向定位槽24、25之環形開口外側各設有一內凸肋26，各內凸肋26向內徑向形成一傾斜面261，而利於定位凸緣15、32導引進入對應之第一、第二周向定位槽24、25內，且藉由各凸緣對周向定位槽之內凸肋推擠 作用，而外突變形，從而令該插塞件21外壁上、下部分別緊貼容置空間121周向內壁，進而形成雙重的周向密封效果。 In particular, in order to enable the plug member 21 to be tightly joined to the circumferential inner wall of the accommodating space 12, the first and second circumferential positioning grooves 24, 25 are respectively outside the annular opening. An inner rib 26 is disposed, and each inner rib 26 forms an inclined surface 261 inwardly in the radial direction, and the positioning flanges 15, 32 are guided into the corresponding first and second circumferential positioning grooves 24, 25, and Pushing the ribs in the circumferential positioning groove by the flanges The function is externally mutated, so that the upper and lower portions of the outer wall of the plug member 21 are respectively in close contact with the circumferential inner wall of the accommodating space 121, thereby forming a double circumferential sealing effect.
格柵件3係由絕緣材料，例如塑膠所製成，其頂面對應第二周向定位槽25、通孔22及端子槽13位置分別突設一第二定位凸緣32及複數個穿孔33，該等穿孔33供端子14之導線141穿出。此外，該格柵件3外壁對應裙部12之一對扣槽16位置突設一對突出物31；因此，如圖3a所示，當該格柵件3套入容置空間121內時，該對突出物31即卡扣於扣槽16，以形成如圖2及圖3b之鎖定狀態，並使該格柵件3推擠該密封圈2。 The grid member 3 is made of an insulating material, such as plastic, and a second positioning flange 32 and a plurality of perforations 33 are respectively protruded from the top surface of the second circumferential positioning groove 25, the through hole 22 and the terminal slot 13 respectively. The perforations 33 are for the wires 141 of the terminal 14 to pass through. In addition, a pair of protrusions 31 are protruded from the outer wall of the grill member 3 corresponding to one of the skirts 12 at the position of the buckle groove 16; therefore, as shown in FIG. 3a, when the grill member 3 is nested in the accommodating space 121, The pair of protrusions 31 are snapped onto the buckle groove 16 to form a locked state as shown in FIGS. 2 and 3b, and the grill member 3 is pushed against the seal ring 2.
此外，該格柵件3具有突出物31之一對外壁進一步向下延伸一對翼片34；當按壓該對翼片34時，可令突出物31與扣槽16脫離，進而形成解鎖。 In addition, the grill member 3 has a pair of protrusions 31 extending further downwardly from the pair of fins 34; when the pair of flaps 34 are pressed, the protrusions 31 can be disengaged from the buckle groove 16 to form an unlock.
請參閱圖3a，本案第一實施例組裝時，首先將密封圈2套入殼體1底部之容置空間121內，使該插塞件21頂面之第一周向定位槽24插接於該容置空間121頂部內壁之第一定位凸緣15。接著，將格柵件3套入殼體1底部之容置空間121內，使其頂面之第二定位凸緣32插接於插塞件21底面之第二周向定位槽25。此時，因突出物31尚未卡扣於扣槽16，所以該插塞件21周面外壁尚未緊貼容置空間121之周向內壁。請參閱圖3b最後繼續向格柵件3施力，使突出物31卡扣於扣槽16內，而插塞件21受到格柵件3的施力作用，讓各凸緣15、32對所屬之周向定位槽24、25之內凸肋26形成推擠而外突變形，從而令該插塞件21外壁上、下部分別緊貼容置空間121周向內壁，進而形成雙重的周向密封效果。 Referring to FIG. 3a, in the first embodiment of the present invention, the sealing ring 2 is first inserted into the accommodating space 121 at the bottom of the housing 1 so that the first circumferential positioning groove 24 of the top surface of the plug member 21 is inserted into the housing. The first positioning flange 15 of the inner wall of the top of the accommodating space 121. Then, the grid member 3 is inserted into the accommodating space 121 at the bottom of the casing 1 such that the second positioning flange 32 of the top surface is inserted into the second circumferential positioning groove 25 of the bottom surface of the plug member 21. At this time, since the protrusion 31 is not yet engaged with the buckle groove 16, the outer wall of the circumferential surface of the plug member 21 is not yet in close contact with the circumferential inner wall of the accommodation space 121. Referring to FIG. 3b, the force is continuously applied to the grill member 3 so that the protrusion 31 is snapped into the buckle groove 16, and the plug member 21 is biased by the grill member 3, so that the flanges 15 and 32 belong to each other. The ribs 26 of the circumferential positioning grooves 24, 25 are pushed and externally deformed, so that the upper and lower portions of the outer wall of the plug member 21 are closely attached to the circumferential inner wall of the accommodating space 121, thereby forming a double circumference. The sealing effect.
如圖4至圖6b所示，本案之電連接器之第二實施例亦由一殼體1，一密封圈2，及一格柵件3所組成。 As shown in FIG. 4 to FIG. 6b, the second embodiment of the electrical connector of the present invention is also composed of a casing 1, a sealing ring 2, and a grating member 3.
其中，該殼體1及格柵件3的結構與第一實施例相同，在此不擬贅述。 The structure of the housing 1 and the grill member 3 is the same as that of the first embodiment, and is not described herein.
而該密封圈2異於第一實施例在於，該密封圈2之插塞件21周向表面突設至少一外凸肋27，如圖4所示，該插塞件21周向表面鄰近頂、底端分別突設一外凸肋27為佳。而該第一、第二周向定位槽24、25之環形開口外側向內徑向形成一導引斜面28，以利於定位凸緣15、32導引進入對應之第一、第二周向定位槽24、25內，並藉由各凸緣對周向定位槽之推擠作用，使鄰接容置空間周向內壁之兩外凸肋擠壓變形，從而令該插塞件21外壁上、下部分別緊貼容置空間121周向內壁，進而形成雙重的周向密封效果。 The sealing ring 2 is different from the first embodiment in that at least one outer rib 27 protrudes from the circumferential surface of the plug member 21 of the sealing ring 2, and the circumferential surface of the plug member 21 is adjacent to the top as shown in FIG. Preferably, a protruding rib 27 is protruded from the bottom end. And a guiding slope 28 is formed radially inward of the annular opening of the first and second circumferential positioning grooves 24, 25 to facilitate the positioning of the positioning flanges 15, 32 into the corresponding first and second circumferential positions. In the grooves 24, 25, and by the pushing action of the flanges on the circumferential positioning grooves, the two outer ribs adjacent to the circumferential inner wall of the accommodating space are pressed and deformed, so that the outer wall of the plug member 21 is The lower portions respectively abut the circumferential inner wall of the accommodating space 121, thereby forming a double circumferential sealing effect.
請參閱圖6a，本案第二實施例組裝時，首先將密封圈2套入殼體1底部之容置空間121內，使該插塞件21頂面之第一周向定位槽24插接於該容置空間121頂部內壁之第一定位凸緣15。接著，將格柵件3套入殼體1底部之容置空間121內，使其頂面之第二定位凸緣32插接於插塞件21底面之第二周向定位槽25。此時，因突出物31尚未卡扣於扣槽16，所以該插塞件21周面外壁之上、下外凸肋27鄰接該容置空間121之周向內壁。請參閱圖6b，最後向格柵件3繼續施力，使突出物31卡扣於扣槽16內，而插塞件21受到格柵件3的施力作用，讓各凸緣15、32對所屬之周向定位槽24、25進行推擠，而使鄰接容置空間121周向內壁之外凸肋27擠壓變形，從而令該插塞件21外壁上、下部分別緊貼容置空間121周向內壁，進而形成雙重的周向密封效果。 Referring to FIG. 6a, in the second embodiment of the present invention, the sealing ring 2 is first inserted into the accommodating space 121 at the bottom of the housing 1 so that the first circumferential positioning groove 24 of the top surface of the plug member 21 is inserted into the housing. The first positioning flange 15 of the inner wall of the top of the accommodating space 121. Then, the grid member 3 is inserted into the accommodating space 121 at the bottom of the casing 1 such that the second positioning flange 32 of the top surface is inserted into the second circumferential positioning groove 25 of the bottom surface of the plug member 21. At this time, since the protrusion 31 is not yet engaged with the buckle groove 16, the upper surface of the peripheral surface of the plug member 21 and the lower outer rib 27 are adjacent to the circumferential inner wall of the accommodating space 121. Referring to FIG. 6b, finally, the force is continuously applied to the grill member 3 to cause the protrusion 31 to be snapped into the buckle groove 16, and the plug member 21 is biased by the grill member 3, so that the flanges 15 and 32 are paired. The circumferential positioning grooves 24 and 25 are pushed, and the ribs 27 are pressed and deformed toward the inner wall of the adjacent accommodating space 121, so that the upper and lower portions of the outer wall of the plug member 21 are closely attached. The space 121 circumferentially faces the inner wall, thereby forming a double circumferential sealing effect.
所以，經由本案之實施，其所增益之功效在於，該電連接器內部密封圈之密封結構係設於的堅固位置，例如該插塞件頂、底面外壁與通孔間的區域內分別軸向開設環形之第一、第二周向定位槽，除可提供最佳的密封效果外，且因插塞件後側未設有軸向延伸之周向凸緣，所以不致發生凸緣損毀的情況。同時，該插塞件除具有與導線單獨密封的功能外，另藉由該第一、第二周向定位槽之環形開口外側各設有一內凸肋，或者該插塞件周向表面突 設至少一外凸肋，該內凸肋或外凸肋受到第一、第二定位凸緣的推擠，使插塞件周向外壁外突變形，並緊貼容置空間周向內壁，據以形成周向密封的接合效果，堪稱同類物品前所未見的一大佳構。 Therefore, the effect of the gain of the present invention is that the sealing structure of the inner sealing ring of the electrical connector is disposed at a solid position, for example, the axial direction between the top surface of the plug member and the outer wall of the bottom surface and the through hole respectively. The first and second circumferential positioning grooves of the ring are provided, in addition to providing an optimal sealing effect, and since the rear side of the plug member is not provided with an axially extending circumferential flange, the flange is not damaged. . At the same time, in addition to the function of sealing the wire separately, the plug member is provided with an inner rib by the outer side of the annular opening of the first and second circumferential positioning grooves, or the circumferential surface of the plug member is protruded. Providing at least one outer rib, the inner rib or the outer rib being pushed by the first and second positioning flanges, so that the plug member is outwardly deformed outwardly from the outer wall and closely adjacent to the circumferential inner wall of the accommodating space.
