The invention aims to provide a connector with a sealing element observation structure, which is used for solving the problem that workers cannot judge the damage condition of a sealing element in the existing connector; it is also an object of the present invention to provide a lock nut for a connector used in the connector, and a connector assembly using the connector.
In order to achieve the above object, the aspect 1 of the connector with a seal observation structure of the present invention is: the connector with the sealing element observation structure comprises a plug body/socket body and a locking nut sleeved on the plug body/socket body, wherein a radial sealing groove for installing a radial sealing element is formed in an inserting section of the plug body/socket body, which is used for inserting the corresponding socket/plug, a notch of the radial sealing groove faces towards the locking nut, and an observation structure for observing the radial sealing element in the radial mounting groove to judge the damage condition of the radial sealing element is arranged on the side wall of the locking nut.
Solution 2 is the connector according to solution 1, wherein the observation structure is formed by an observation hole penetrating through a side wall of the lock nut in a radial direction of the lock nut.
The lock nut for the connector of the present invention has the following configuration in scheme 1: the side wall of the lock nut for the connector is provided with an observation structure for observing the radial seal member mounted in the radial mounting groove on the connector plug/socket.
Solution 2 is the lock nut according to solution 1, wherein the observation structure is formed by an observation hole penetrating through a side wall of the lock nut in a radial direction of the lock nut.
Solution 2 is the connector assembly according to solution 1, wherein the viewing structure is formed by a viewing hole extending through a side wall of the lock nut in a radial direction of the lock nut.
The invention has the beneficial effects that: when the connector is assembled, the radial sealing element is arranged in the radial sealing groove on the plug, the plug is inserted into the socket, and the plug and the socket are axially locked by rotating the locking nut. After the connector is used for a period of time, the plug is pulled out of the socket, the damage condition of the radial sealing element is judged through the observation hole in the lock nut, and if the radial sealing element is seriously damaged, the sealing element needs to be replaced. Compared with the prior art, the replacement of the radial sealing element is more reasonable, the situation that the sealing element is not replaced timely or the sealing element is wasted can not be caused, and the sealing performance of the connector is not easy to influence.
Furthermore, the observation structure is formed by the observation hole arranged on the lock nut, the observation hole is simple to manufacture, and the manufacturing cost is low; when the radial sealing element is used, the damaged condition of the radial sealing element can be observed at a full angle by rotating the lock nut, and the radial sealing element is more convenient to use.
Drawings
FIG. 1 is a schematic view of a prior art connector with a double layer radial seal structure;
fig. 2 is a schematic structural view of a first embodiment of the connector with a seal observation structure according to the present invention.
Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
The first embodiment of the connector with a seal observing structure of the present invention, as shown in fig. 2, includes a plug 1 and a lock nut 3 sleeved on the plug 1, and a space 2 between the plug 1 and the lock nut 3 is provided for a socket to be installed. The lock nut 3 is used for locking the plug 1 with a corresponding socket. A clamping ring 5 is arranged on the plug 1 at the rear side of the locking nut 3 along the plugging direction of the plug 1, and the clamping ring 5 limits the axial position of the locking nut 3 on the plug 1.
A radial sealing groove is formed in the circumferential outer wall of the plug 1, which is used for being connected with the socket in an inserting mode, and a notch of the radial sealing groove faces the locking nut 3; more than two radial seal grooves are arranged at intervals along the axial direction of the plug 1, and each radial seal groove is internally provided with a radial seal 4. During the use of the connector, the radial seal 4 is easily damaged along with the accumulation of the plugging times of the plug and the socket.
The lock nut 3 is provided with an observation hole 6 for observing the damaged condition of the radial sealing element 4, and the observation hole is a light hole which radially penetrates through the side wall of the lock nut 3 along the lock nut 3. In this embodiment, two radial seal grooves all correspond and have observation hole 6, and each observation hole 6 is close to the setting of corresponding circumferential seal groove on lock nut 3. In other embodiments, more than two viewing apertures 3 corresponding to the same radial seal groove are provided at axially spaced intervals around the lock nut 3.
When the connector is assembled, the radial sealing element 4 is firstly installed in the corresponding radial sealing groove, the plug 1 is inserted into the corresponding socket, and the locking nut 3 is screwed on, so that the axial locking of the plug 1 and the corresponding socket is realized. After the connector is used for a period of time, the plug 1 is pulled out of the socket, the corresponding radial sealing element 4 can be observed through the observation hole 6, and then the damage condition of the radial sealing element 4 is judged.
Compared with the prior art, the problem that the damage condition of the radial sealing element in the existing connector cannot be judged is solved; and the damaged condition of radial seal spare is judged comparatively accurately, is difficult to cause the condition that the sealing member is changed untimely or the sealing member is changed too frequently and cause the sealing member extravagant.
The second embodiment is different from the first embodiment in that the observation hole is a threaded hole, and a screw plug is screwed in the threaded hole. When the connector is normally used, the plug screw is vertically and rotatably arranged on the observation hole, so that impurities in the external environment are prevented from entering the connector; when observation is needed, the screw plug is screwed off; alternatively, the screw plug may be replaced with another member made of a transparent material.
The third embodiment is different from the first embodiment in that the observation structure on the lock nut is formed by an arc-shaped groove arranged around the axis of the lock nut, and the lock nut can be additionally provided with a shielding cover for shielding the arc-shaped groove; when needing to observe, the shielding cover is detached.
A fourth embodiment, which is different from the first embodiment in that the observation structure on the lock nut is formed by a waist-shaped long hole extending along the axial direction of the lock nut, and the waist-shaped long hole crosses two radial seal grooves on the plug; two radial sealing elements on the two radial sealing grooves can be observed simultaneously through the waist-shaped long hole.
In the embodiment of the lock nut for a connector according to the present invention, the structure of the lock nut for a connector is the same as that of the lock nut in any of the embodiments of the connector with a seal observation structure according to the present invention described above. Therefore, the description will not be repeated.
An embodiment of the connector assembly of the present invention, which includes a plug/receptacle connector serving as a plug/receptacle, has the same structure as that of any of the above-described embodiments of the connector with a seal observing structure of the present invention, and a description thereof will not be repeated.
