Description
Technical Field
[0001] The utility model relates to the technical field of connectors, and more specifically, to an anti-touch connector. Background Art
[0002] At present, some connectors use columnar power terminals for end-face conductive contact to transmit electric energy, and the power terminals arranged in the plug and the socket are connected by screws to ensure good contact of the conductive end faces. In these connectors, based on safety requirements, anti-touch structures need to be provided on the power terminals of the plug and the socket. The anti-touch structure usually includes a cylindrical anti-touch cap, and the anti-touch cap is installed in a connection hole preset in the power terminal for inserting a screw or arranging an internal thread structure, and one end of the anti-touch cap extends out of the conductive end face of the power terminal. Further, an anti-touch sleeve is also injection-molded on the outer side of the terminal on the housing, and the anti-touch sleeve and the anti-touch cap cooperate to achieve the purpose of preventing the power terminal from being touched.
[0003] However, in the above anti-touch structure, there is an annular gap between the anti-touch sleeve and the anti-touch cap. When a finger or a tool enters the annular gap and applies pressure, if the finger or the tool shakes, since the annular gap cannot effectively prevent the shaking, the finger or the tool still has a high possibility of continuing to penetrate into the annular gap, increasing the probability of touching the power terminal. Therefore, it is necessary to develop a new anti-touch structure to improve the anti-touch performance of the connector. Summary of the Utility Model

[0033] Now, various exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present invention.
[0034] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation to the present invention and its application or use.
[0035] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods and devices should be regarded as part of the specification.
[0036] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.
[0037] As Figure 1As shown in the figure, an embodiment of the present utility model provides an anti-touch connector, which includes a plug 1 and a socket 2 that are adaptively connected. The plug 1 includes a plug housing 11 and a plug terminal 13. The plug terminal 13 is connected with a flat ribbon cable 131. The socket 2 includes a socket housing 21 and a socket terminal 23. Connection holes are correspondingly arranged on the inner sides of the plug terminal 13 and the socket terminal 23, and the two are connected by a connecting piece passing through the connection holes. The connection holes are divided into a plug connection hole 133 and a socket connection hole 232. On the opposite conductive end faces of the plug terminal 13 and the socket terminal 23, a number of slots that are axially recessed inward are correspondingly arranged. The slots are respectively a plug slot 132 and a socket slot 231. A first anti-touch member 14 with an end extending axially to the outside of the slot is inserted into the slot of one of them, and the slot of the other is used to accommodate the end of the first anti-touch member 14 extending to the outside of the slot when the plug 1 and the socket 2 are matingly connected.
[0038] Considering that in actual assembly, the socket 2 is in a fixed static state, while the plug 1 is in a movable dynamic state before being connected to the socket 2, and it is more likely to have a touch risk than the socket 2. Therefore, the anti-touch requirement of the plug 1 is more obvious. As Figure 2-8 shown, in this embodiment, the first anti-touch member 14 is inserted into the slot of the plug terminal 13, that is, the plug slot 132. A third anti-touch member 24 with a free end located outside the socket terminal 23 is arranged in the connection hole of the socket terminal 23, that is, the socket connection hole 232. A through hole for the connecting piece to pass through is arranged in the third anti-touch member 24. When the plug 1 and the socket 2 are matingly connected, the free end of the third anti-touch member 24 extends into the connection hole of the plug terminal 13, that is, the plug connection hole 133.
[0039] The above-mentioned first anti-touch member 14 divides the annular space in front of the conductive end face of the plug terminal 13. After a finger or a tool enters the annular space, on the one hand, the first anti-touch member 14 can block the finger or the tool from entering the annular space, and on the other hand, it can effectively prevent the finger or the tool from shaking, thereby preventing the finger or the tool from continuing to enter, so as to ensure that the finger or the tool cannot contact the conductive end face, improving the anti-touch performance. Moreover, the first anti-touch member 14 can also effectively prevent various other foreign objects from entering the annular space and contacting the conductive end face, further enhancing the anti-touch performance.
[0040] In other embodiments, according to the foregoing description, the first anti-touch member 14 can also be inserted into the slot of the socket terminal 23, that is, the socket slot 231. The slot of the plug terminal 13, that is, the plug slot 132, is used to accommodate the end of the first anti-touch member 14 extending to the outside of the socket slot 231 when the plug 1 and the socket 2 are matingly connected.
[0041] Furthermore, in order to optimize the structure to further improve the anti-touch ability of the first anti-touch member 14, as Figure 6 、 7As shown, in this embodiment, a plug anti-touch sleeve 12 is disposed around the outside of the plug terminal 13. The slot penetrates through the plug terminal 13 and the socket terminal 23 in the radial direction to form the above-mentioned plug slot 132 and socket slot 231. The first anti-touch member 14 is composed of a plurality of plug-in plates 141 respectively inserted into a plurality of plug slots 132. The plug-in plates 141 are flat. The outer sides of the plurality of plug-in plates 141 in the radial direction are connected to the inner peripheral wall of the plug anti-touch sleeve 12. A connecting cylinder 142 for a connecting member to pass through is provided on the inner peripheral wall of the connection hole of the plug terminal 13, that is, the inner peripheral wall of the plug connection hole 133. The connecting cylinder 142 can be regarded as a part of the first anti-touch member 14. The inner sides of the plurality of plug-in plates 141 in the radial direction are connected to the outer peripheral wall of the connecting cylinder 142. Thus, each plug-in plate 141 divides the conductive end face of the plug terminal 13 into a plurality of fan-shaped spaces, with a more reasonable structure and stronger anti-touch ability. After the plug 1 is connected to the socket 2, the free end of the above-mentioned third anti-touch member 24 is actually inserted into the inside of the connecting cylinder 142.
[0042] In other embodiments, the first anti-touch member 14 can also be other applicable structures. For example, the plug-in plate 141 of the first anti-touch member 14 is a wavy structure or an arc-shaped structure in the radial direction, etc., or the first anti-touch member 14 is an integral structure. For example, the above-mentioned plug-in plates 141 are connected into an integral structure through a circular ring, but each plug-in plate 141 is not connected to the plug anti-touch sleeve 12 and the connecting cylinder 142. The plug slot 132 and the socket slot 231 should be adapted to the shape of the first anti-touch member 14. The above-mentioned schematic example structures can be understood and clarified by those skilled in the art according to the description, so no more detailed description will be shown in the drawings.
[0043] Furthermore, in order to enhance the anti-touch performance of the socket terminal 23 and guide and position the first anti-touch member 14 when the plug 1 and the socket 2 are mated and connected, so that the first anti-touch member 14 can smoothly and correctly enter the socket slot 231, as Figure 2-5 shown, in this embodiment, a guiding sleeve 25 is provided outside the socket terminal 23. One end of the guiding sleeve 25 facing the plug terminal 13 extends out of the conductive end face of the socket terminal 23. A plurality of guiding grooves 251 corresponding to the plurality of slots are provided on the guiding sleeve 25. When the plug 1 and the socket 2 are mated and connected, the guiding sleeve 25 is inserted into the gap between the plug anti-touch sleeve 12 and the plug terminal 13, that is, the first gap 16, and the outer side of the first anti-touch member 14 in the radial direction is received in the guiding grooves 251 and the slots.
[0044] Furthermore, in order to obtain better structural strength and stable performance, and to facilitate processing and molding and avoid secondary assembly, in the present embodiment, the plug terminal 13 is embedded and injection molded in the plug housing 11, and the first anti-touch member 14 and the plug anti-touch sleeve 12 are integrally injection molded with the plug housing 11. When the first anti-touch member 14 and the plug anti-touch sleeve 12 are integrally injection molded, since the first anti-touch member 14 can prevent the plug terminal 13 from escaping from the plug housing 11, the first anti-touch member 14 also has a certain function of preventing the plug terminal 13 from escaping from the plug housing 11; the socket terminal 23 is embedded and injection molded in the socket housing 21, and the guide sleeve 25 is integrally injection molded with the socket housing 21.
[0045] In addition, in the present embodiment, a socket anti-touch sleeve 22 is further provided on the outer side of the guide sleeve 25. When the plug 1 is mated and connected with the socket 2, the plug anti-touch sleeve 12 enters into the gap between the socket anti-touch sleeve 22 and the guide sleeve 25, i.e., the second gap 27. The socket anti-touch sleeve 22 is also integrally injection molded with the socket housing 21.
[0046] As a commonly used connection means for end-face contact type conductive connection, in this embodiment, the connecting member is a screw 15 inserted into the connection hole of the plug terminal 13 and the socket terminal 23, and the connection hole of the socket terminal 23, that is, the socket connection hole 232, is provided with an internal thread structure that matches the thread of the screw 15. The screw 15 can be made of iron / iron alloy, and the end of the screw 15 facing the socket terminal 23 can be wrapped with an insulating cap 151 of plastic material, so that when the screw 15 is pre-installed in the plug connection hole 133 and the plug 1 is not connected to the socket 2, it can play an anti-touch function. In conjunction with the first anti-touch member 14, the anti-touch ability of the plug terminal 13 can be further improved.
[0047] Furthermore, since the socket terminal 23 is made of copper / copper alloy and is relatively soft, in order to prevent the internal thread structure directly processed in the socket connection hole 232 from deforming and affecting the connection performance, Figure 4 As shown, in this embodiment, a nut sleeve 26 with a hardness greater than that of the socket terminal 23 is fixedly installed in the connection hole of the socket terminal 23, that is, the socket connection hole 232. The fixed installation method can be a riveting connection. The nut sleeve 26 can be made of iron / iron alloy. The nut sleeve 26 has an internal threaded hole 261, and the internal threaded hole 261 constitutes the aforementioned internal thread structure. Therefore, through the connection between the screw 15 and the nut sleeve 26, the socket connection hole 232 can be effectively prevented from being deformed and affecting the connection performance.
[0048] In this embodiment, the inner threaded hole 261 of the nut sleeve 26 can be connected to the cable corresponding to the socket 2 through another screw 15 at one end away from the screw 15 , so that the cable is conductively connected to the socket terminal 23 .
[0049] Furthermore, in order to prevent the third anti-touch member 24 from unexpectedly detaching from the socket terminal 23 , in this embodiment, the third anti-touch member 24 is fixedly mounted on the inner wall of the connection hole of the socket terminal 23 , ie, the socket connection hole 232 .
[0050] Specifically, considering the convenience of installation and stability after installation, such as Figure 3 , 4 As shown, a first clamping platform 241 extending in the circumferential direction is provided on the outer wall surface of the end of the third anti-touch member 24 opposite to the free end, and a second clamping platform 233 extending in the circumferential direction is provided on the inner circumferential wall of the connecting hole of the socket terminal 23, i.e., the socket connecting hole 232. After the third anti-touch member 24 is inserted into the connecting hole of the socket terminal 23, i.e., the socket connecting hole 232, the third anti-touch member 24 abuts against the nut sleeve 26, and the first clamping platform 241 passes over the second clamping platform 233 and cooperates with its stopper to realize that the third anti-touch member 24 is fixedly connected to the connecting hole of the socket terminal 23, i.e., the inner wall of the socket connecting hole 232.
[0051] Another embodiment of the present invention provides a touch-proof connector, such as Figure 9 As shown, the difference from the previous embodiment is that a second anti-touch member 3 with an end located on the inner side of the socket slot 231 is inserted into the socket slot 231 of the socket terminal 23, and the second anti-touch member 3 is connected to the inner circumferential wall of the guide sleeve 25 on the radial outer side. When the plug 1 and the socket 2 are mated and connected, the end of the first anti-touch member 14 extends into the slot of the other and abuts against the second anti-touch member 3.
[0052] In this embodiment, the second anti-touch member 3 is connected to the inner circumferential wall of the guide sleeve 25 on the radial outer side, thereby providing a certain holding force for the socket terminal 23 to prevent the socket terminal 23 from falling out of the socket housing 21. The second anti-touch member 3 and the guide sleeve 25 can be connected by integral injection molding.
[0053] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
