Abstract
The invention relates to the field of electrical connectors, particularly to a flame-proof connector assembly. The flame-proof connector assembly comprises a plug and a socket; the socket comprises a casing and an accessory; the accessory comprises a sleeve; the casing is a square plate casing; a square plate of the square plate casing is provided with a connecting hole; the front end of the sleeve of the accessory is provided with external threads which are used for being in threaded connection with an installation hole formed in a flame-proof box body; the rear end of the casing is inserted into the sleeve; the front end of the sleeve is provided with a flame-proof joint surface which is matched with the peripheral surface of the square plate casing in a sealing mode. According to the flame-proof connector assembly, the requirements of the flame-proof connector socket for the machining accuracy of the flame-proof box body are reduced and meanwhile the problem that the existing flame-proof connector assembly is inconvenient to operate is solved.
Description
Technical field
The present invention relates to electric connector field, particularly relate to a kind of flame proof connector assembly.
Background technology
Flame proof connector assembly is a kind of electric connector be mainly used on flameproof cabinet, and compared with common electric connector, the sealing of the socket of flame proof connector assembly and the cooperation place of anti-explosion box body has higher requirement.The flame proof connector body of existing flameproof cabinet mainly contains two kinds of installation forms: cylinder composition surface is installed and is threadedly engaged face and installs.
Cylinder composition surface is installed: because the clearance requirement of cylinder faying face to mating surface is strict, and flameproof cabinet and flame proof connector body are produced in different places often, this has higher requirement with regard to giving the accuracy of manufacture of flameproof cabinet, bring very large difficulty to the manufacturer of flameproof cabinet, make the more difficult control of final fit clearance of flameproof cabinet and flame proof connector body; In addition, the flame proof connector body on existing conventional employing cylinder composition surface is not often with annex, the range of application of product is restricted, can only be used for the flameproof cabinet that volume is less.
The face that is threadedly engaged is installed: the screw thread process that existing employing is threadedly engaged the flame proof connector body of face mounting structure, with on the sleeve of its one or square plate, coordinates with the respective threaded that flameproof cabinet is processed during use.Therefore, when assembling, flame proof connector body needs to rotate along with screwing of screw thread, but now flame proof connector carefully connects the wire, therefore can bring very large difficulty to operation; In addition, because of screw thread be screwed into position after the true bearing of flame proof connector body is bad determines, plug together use to follow-up flame proof connector follow-up and bring inconvenience.
Summary of the invention
The object of the present invention is to provide a kind of flame proof connector assembly, to reduce the requirement of flame proof connector body to flameproof cabinet machining accuracy, solve the unhandy problem of existing flame proof connector assembly simultaneously.
In order to solve the problem, flame proof connector assembly is by the following technical solutions: flame proof connector assembly, comprise plug and socket, plug and socket is inserted terminal separately with front end, plug comprises plug casing, socket comprises Socket casing and annex, annex comprises sleeve, described Socket casing is square plate housing, the square plate of square plate housing is provided with connecting hole, the barrel forward end of annex is provided with the external screw thread for being threaded with the installing hole on flameproof cabinet, the rear end of Socket casing is inserted in sleeve, the front end place of sleeve is provided with the explosion-proof composition surface be sealed and matched with the outer peripheral face of Socket casing.
Sealing ring is provided with between sleeve and the outside wall surface of Socket casing.
The endoporus of described sleeve is the stepped hole including the large and small footpath section one in front and one in back arranged, and the rear end of Socket casing is inserted in the large footpath section of the endoporus of sleeve, and the length of large footpath section is not less than the length of the part of the inserted sleeve of Socket casing.
Because the square plate of the housing of the socket of flame proof connector assembly of the present invention is provided with connecting hole, the sleeve of annex is provided with external screw thread, therefore, when in use, be fixedly connected with flameproof cabinet by connecting hole housing, be fixedly connected with flameproof cabinet by the external screw thread of sleeve, simultaneously using sleeve with the part coordinated of flameproof cabinet as the composition surface with flameproof cabinet, ensure sealing, the flame proof connector body coordinated with flameproof cabinet by screw thread then reduces the requirement on machining accuracy to flameproof cabinet; Meanwhile, the cooperation place plugging together housing together and sleeve forms explosion-proof composition surface, thus ensure being sealed and matched of flame proof connector body and flameproof cabinet on the whole, and housing and sleeve are all by connector manufacturer production in field of connectors, be easier to the matching ensured therebetween, in sum, the socket of flame proof connector assembly of the present invention reduces the requirement of flame proof connector body to flameproof cabinet machining accuracy, solves the unhandy problem of existing flame proof connector assembly simultaneously.
Accompanying drawing explanation
Fig. 1 is the front view (band is analysed and observe) of the socket in the embodiment of flame proof connector assembly;
Fig. 2 is the left view of the socket in the embodiment of flame proof connector assembly.
Embodiment
The embodiment of flame proof connector assembly, comprises plug and socket, and plug and socket take front end as inserted terminal separately, and plug comprises plug casing, and as shown in Figure 1-2, it comprises housing 11 and annex to the structure of socket.
Housing 11 is square plate housing, and the square plate of square plate housing is provided with connecting hole 12, and connecting hole 12 is for being fixedly connected with corresponding anti-explosion box body, and in the present embodiment, connecting hole 12 has four, and four connecting holes 12 lay respectively on four angles of square plate.Sealed to each other in order to what ensure between square plate and anti-explosion box body further, the trailing flank place of square plate is also provided with sealing gasket 13.
Annex comprises sleeve 14, sleeve 14 front end is provided with the external screw thread for being threaded with the installing hole on flameproof cabinet, the rear end of housing 11 has an inserting paragraph, inserting paragraph is inserted in sleeve 14, the front end place of sleeve 14 is provided with the explosion-proof composition surface be sealed and matched with the outer peripheral face of square plate housing, in the present embodiment, the section of the outside wall surface of inserting paragraph, the internal face at barrel forward end place is all rounded, and the internal face at the front end place of its middle sleeve 14 defines the explosion-proof composition surface be sealed and matched with the outer peripheral face of the inserting paragraph of housing 11.In the present embodiment, the endoporus of sleeve 14 is stepped hole, it comprises the large footpath section being positioned at front end and the path section being positioned at rear end, the length of large footpath section is not less than the length of the part of the inserted sleeve of housing 11, in the present embodiment, namely the length of large footpath section is not less than the length of the inserting paragraph of housing 11, is to ensure that sleeve 14 is not interfered with housing like this, ensures that housing 11 can be seated.In order to ensure the sealing between housing 11 and sleeve 14 further, between the outside wall surface of sleeve 14 and housing 11, be also provided with sealing ring 15.
When assembling the socket of this flame proof connector assembly, first by the external screw thread on sleeve, sleeve and flameproof cabinet can be linked together, then housing being inserted into backward sleeve and fixing by arranging securing member in connecting hole.
