Description

一种NAT地址转换装置 One kind of address translation NAT

技术领域 FIELD

[0001] 本发明涉及一种NAT地址转换装置。 [0001] The present invention relates to an address translation NAT device.

背景技术 Background technique

[0002] 现有的NAT地址转换装置上设置有若干通讯接口,前置服务器、路由器和其他NAT地址转换装置分别与不同通讯接口之间连接有数据线,以解决远动终端地址变更、远动终端对应多个前置系统负载过高、调度自动化前置系统负载不均衡且缺乏状态检测、多个前置系统切换冗余可靠性问题等。 [0002] provided with a plurality of communication interfaces, front-servers, routers, and other conventional NAT address conversion means NAT address conversion means respectively connected between different communication interfaces and data lines, to address the address change remote terminal, remote corresponding to the plurality of front-end system load is too high, front SCADA system load imbalance and lack of state detection, switching the plurality of front-end system redundancy reliability problems. 由于通讯接口在NAT地址转换装置上的开口朝向无法改变,因而,数据线将无法自适应通讯接口的位置移动,在技术人员移动NAT地址转换装置的摆放位置后,至少一根数据线将会始终处于弯折状态,这将缩小NAT地址转换装置的运动范围。 Since the communication port opening in the NAT address translation means can not change the orientation, and thus, the data line can not position the adaptive communication interface, after placement of the art mobile devices NAT address translation, at least one data line will always in the folded state, this will narrow the range of motion of the NAT address conversion device.

发明内容 SUMMARY

[0003] 本发明提供一种NAT地址转换装置,增加NAT地址转换装置的运动范围。 [0003] The present invention provides a NAT address translation, increasing the range of motion of the NAT address conversion means.

[0004] 为解决上述问题,本发明提供如下技术方案: [0004] In order to solve the above problems, the present invention provides the following technical solutions:

[0005] —种NAT地址转换装置,包括盖体、壳体和接线端子,所述壳体为圆筒形壳体,所述壳体设有开口朝上的安装槽,所述盖体盖设在所述安装槽的槽口处,所述壳体的侧壁上设有与安装槽连通的限位孔,所述接线端子侧壁上设有通讯接口,所述通讯接口对应所述限位孔,所述安装槽位于限位孔下方的侧壁上设有支撑板,所述接线端子一端与所述支撑板铰接,其铰接处形成轴心,所述接线端子另一端插入限位孔内,所述接线端子另一端上设有螺杆,所述螺杆穿过限位孔延伸至壳体外,所述螺杆上套有螺母,所述接线端子绕轴心转动至预定位置后,螺母沿螺杆轴向运动并与壳体相抵。 [0005] - species NAT address conversion means includes a cover, the housing and the terminals, the housing is a cylindrical housing, said housing is provided with a mounting groove opening upward, the cover lid is provided notch of said mounting groove, said limiting hole is provided with a mounting groove on the sidewall of the housing in communication with said terminal communication interface on the side walls, the communication interface corresponding to the spacing holes, the mounting groove is located on a sidewall of the stopper is provided with holes below the support plate, said terminal end of said hinge plate support, which is formed at the hinge axis, the other end of the connection terminal insertion hole of the stopper provided with a screw connection on the other end of the terminal, said limiting hole extending through the screw to the outer housing, the sleeve nut on the screw, the said terminal to a predetermined position rotated about the axis, the nut along the screw axis and the movement against the housing.

[0006] 本发明中,接线端子一端与壳体铰接,此结构用于实现通讯接口在壳体上的开口朝向发生改变。 [0006] In the present invention, the terminal end of the hinge housing, the opening of this structure for implementing a communication interface on the housing orientation change.

[0007] 市场上销售的NAT地址转换装置,其通讯接口无法发生改变,这就意味着,当NAT地址转换装置分别与前置服务器、路由器和其他NAT地址转换装置连接时,移动NAT地址转换装置,则至少一根数据线将会始终处于折弯的状态,在数据线发生折弯后,NAT地址转换装置在数据线的驱动下,将会向NAT地址转换装置未移动时的摆放位置方向移动。 [0007] on the market NAT address translation device communication interface changes can not occur, which means that when the NAT address translation device connected to each conversion and pre servers, routers, and other NAT address, mobile NAT address translation device , then at least one data line will be always in the folded state, after the bending occurs in the data line, in the NAT address conversion means driving the data lines will be placed in position when the device is not moving direction of the NAT address conversion mobile.

[0008] 本发明中,接线端子一端与壳体铰接,当NAT地址转换装置分别与前置服务器、路由器和其他NAT地址转换装置连接时,移动NAT地址转换装置,接线端子绕轴心旋转,以避免任意一根数据线处于折弯的状态。 [0008] In the present invention, the housing is hinged at one end terminal, when the address translation NAT device connected to the front respectively converted servers, routers and other NAT address, NAT address translation movement, about the axis of rotation terminals to avoid any data line in a bent state.

[0009] 本发明中,接线端子另一端上设有螺杆,螺杆穿过限位孔延伸至壳体外,此结构方便技术人员在壳体外通过螺母将接线端子另一端固定在壳体上。 [0009] In the present invention, is provided on the other end of the terminal screw which extends through limiting hole to the outer housing, this arrangement conveniently the art by the terminal nut and the other end fixed to the housing outside the housing.

[0010] 现有的NAT地址转换装置通常放置在机房内,机房内具有众多设备,而且,电力公司通常的做法是多个技术人员以轮班的形式,检查机房的设备。 [0010] a conventional address translation NAT device typically placed in the engine room, the engine room with a number of devices, and the power companies is common practice in the art to form a plurality of shift, inspection equipment room. 技术人员不可能记住机房内不同设备的摆放位置,因而,不同的设备需要摆放在固定的位置,并通过铭牌标识该设备的名称、作用、规格等信息。 Technicians can not remember the placement of various devices in the room, so that different devices need to be placed in a fixed position, and identify the name of the device, functions, specifications and other information on the nameplate. 当NAT地址转换装置发生改变后,技术人员无法快速将其找到,并且,技术人员也可能将其他的NAT地址转换装置误认为是自己所要寻找的NAT地址转换装置,这将会严重影响技术人员排除故障的速度。 When the NAT address translation device is changed, the technician can not quickly be found, and technical staff may be other NAT address translation device mistaken themselves are looking for NAT address translation device, it will seriously affect the technical staff excluded speed failure.

[0011] 本发明中,当接线端子绕轴心转动到预定位置后,螺母沿螺杆轴向运动并与壳体相抵,当壳体摆放位置在不经意间发生改变时,技术人员可根据数据线的折弯程度,将壳体摆放至原来的位置。 [0011] In the present invention, when the terminal is rotated around its axis to a predetermined position, and axial movement of the nut along the screw against the housing, when the housing during placement inadvertently changed, according to a data line art the degree of bending, the display housing to the original position.

[0012] 进一步的,所述接线端子位于通讯接口上方的侧壁上设有与螺杆配合的螺纹孔,所述螺杆插入螺纹孔内。 [0012] Further, the terminals located in the screw with a threaded hole in the side wall above the interface of the communication, the screw inserted into the screw hole. 相比螺纹孔设置在接线端子邻近通讯接口的两侧,如此设计,在限位孔尺寸不变的情况下,增加通讯接口相对限位孔运动的范围。 Compared disposed on both sides of the screw hole adjacent the terminal communication interface, so designed, in the case of limiting the same pore size, increasing the relative communication interface limiting movement range of the hole.

[0013] 进一步的,所述螺纹孔与螺杆之间夹持有弹性元件。 [0013] Further, the elastic member sandwiched between the screw hole and the screw. 由于在螺母与壳体不抵触的情况下,螺杆相对接线端子轴向移动,则接线端子易绕轴心旋转,因而,在螺纹孔与螺杆之间夹持有弹性元件,弹性元件可驱使螺杆与螺纹孔分离,从而实现技术人员快速拆除螺杆。 Since in the case where not inconsistent with the housing nut screw connection axially relative to the moving terminal, the terminal about the axis of rotation is easy, therefore, between the screw hole and the screw an elastic member is sandwiched, the elastic member can drive the screw and separating the screw hole, thereby achieving rapid removal of the screw in the art.

[0014] 进一步的,所述NAT地址转换装置还包括簧片,所述簧片一端与盖体连接,其另一端与接线端子相抵。 [0014] Further, the NAT address conversion apparatus further comprises a leaf spring having one end connected to the lid, and the other end against the terminal. 如此设计,方便开启盖体。 So designed, easy to open the lid.

[0015] 进一步的,所述簧片上设有与接线端子配合的限位槽,所述接线端子插入限位槽中。 [0015] Further, the terminal is provided with the upper spring stop groove, said terminal insertion slot limit. 如此设计,方便接线端子插入簧片内。 Thus design, easy connection terminal into the spring.
