Abstract
The utility model relates to a locking screw and a thread locking structure of a connector. The thread locking structure of the connector comprises the locking screw and a nut, wherein the locking screw penetrates through an installation panel, one end of the locking screw is connected with a basic body of a fixed connector located on one side of the installation panel, the other end of the locking screw is located on the other side of the installation panel and provided with an internal thread which can be matched with a free connector in locking mode, the locking screw and the nut are separated, and the outer side corresponding to the end of the locking screw, which is provided with the internal thread, is provided with an external thread, and furthermore the nut is installed on the external thread of the locking screw and therefore tightly presses the installation panel. Accordingly, when the free connector is unscrewed, the fixed connector can not be disentangled from the installation panel.
Description
Technical field
The utility model belongs to field of connectors, relates in particular to the thread locking structure of a kind of lock screw and connector.
Background technique
Connector is to connect two Active Devices, the device of transmission current or signal, and it comprises the fixed connector that is arranged on panel, and the free connector that coordinates with fixed connector.
The thread locking structure of existing connector is generally the integrated exchanging structure of screw-nut, the one end is screw, passing installation panel is threaded with the matrix of the fixed connector that is positioned at installation panel one side, the other end is nut, it is positioned at installation panel away from the opposite side of the matrix of fixed connector, nut has internal thread, can coordinate with free connector, realizes the locking of plug and socket.When the matrix locking of an end of screw and fixed connector, an end of nut just can compress installation panel, thereby fixed connector and installation panel are locked.
The shortcoming of this structure is, when two kinds of connectors will separate, unscrews free connector, can drive thread locking structure and rotate, thereby screw one end and the installation panel of thread locking structure are got loose, and brings many troubles to practical operation.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of lock screw that fixed connector gets loose from installation panel and thread locking structure of connector of can not causing when unscrewing free connector.
The utility model is achieved in that provides a kind of lock screw, and the one end has internal thread, and an end its corresponding outside that described lock screw has described internal thread also is provided with outside thread.
Also be provided with rotation prevention structure near the described lock screw the other end relative with described internal thread, described rotation prevention structure is the polygonal flange.
A kind of thread locking structure of connector, comprise lock screw and nut, described lock screw passes installation panel, the one end is connected with the matrix phase of the fixed connector that is positioned at described installation panel one side, its the other end is positioned at the opposite side of described installation panel, and has an internal thread that can lock with free connector, described lock screw and nut are splits, an end its corresponding outside that described lock screw has described internal thread also is provided with outside thread, and described nut is installed on the outside thread of described lock screw and compresses described installation panel.
Further, the end that described lock screw is connected with the matrix phase of described fixed connector also is provided with rotation prevention structure, and described rotation prevention structure is the polygonal flange, and the matrix of described fixed connector is provided with the recess consistent with described polygonal flange shape.
Further, described lock screw with the Placement of described fixed connector be threaded, rivet, welding or sealing fix.
Further, the quantity of described lock screw is two, is distributed in the both sides of described installation panel, and the quantity of described nut is also two.
Compared with prior art, its lock screw of the thread locking structure of connector of the present utility model and nut are splits, an end its corresponding outside that lock screw has internal thread also is provided with outside thread, thereby nut is installed on and compresses installation panel on the outside thread of lock screw, like this, can not cause fixed connector to get loose from installation panel when unscrewing free connector.
Description of drawings
Fig. 1 is the structural representation of thread locking structure one preferred embodiment of connector in the utility model;
Fig. 2 is the cross-sectional schematic of middle lock screw embodiment illustrated in fig. 1;
Fig. 3 is the schematic top plan view of Fig. 2.
Embodiment
In order to make technical problem to be solved in the utility model, technological scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1 to Figure 3, be a preferred embodiment of the present utility model, the thread locking structure of this connector comprises lock screw 100 and nut 200, lock screw 100 and nut 200 are splits.Lock screw 100 passes installation panel 300, the one end is connected with the matrix 401 of the fixed connector 400 that is positioned at installation panel 300 1 sides, the other end is positioned at the opposite side of installation panel 300, and has the internal thread 101 that can lock with the free connector (not shown).An end its corresponding outside that lock screw 100 has internal thread 101 also is provided with outside thread 102, and nut 200 is installed on the outside thread 102 of lock screw 100, thereby compresses installation panel 300, and connector 400 and installation panel 300 are locked.
In the present embodiment, the quantity of lock screw 100 is two, is distributed in the both sides of installation panel 300, and the quantity of nut 200 is also two.
Particularly, lock screw 100 with the Placement of fixed connector 400 can be threaded, rivet, welding or sealing fixing etc.
In addition, near lock screw 100 the other end relative with internal thread 101, namely with a end that 400 matrix phases of fixed connector are connected near, also be provided with rotation prevention structure 103, rotation prevention structure 103 is the polygonal flange, and the matrix 401 of fixed connector 400 is provided with the recess consistent with the polygonal flange shape (in figure indicate), when lock screw 100 is connected on the matrix 401 of fixed connector 400, rotation prevention structure 103 just can be flush-mounted in recess, thereby realizes anti-rotating function.
In the thread locking structure of above-mentioned connector, lock screw 100 and nut 200 are splits, an end its corresponding outside that lock screw 100 has internal thread 101 also is provided with outside thread 102, nut 200 is installed on the outside thread 102 of lock screw 100, thereby compress installation panel 300, like this, can not cause fixed connector 400 to get loose from installation panel 300 when unscrewing free connector.In addition, lock screw 100 also is provided with rotation prevention structure 103 with the end that 400 matrix phases of fixed connector are connected, and when lock screw 100 was connected on the matrix 401 of fixed connector 400, rotation prevention structure 103 just can be flush-mounted in recess, has anti-rotating function.
