Description

Rectangular connector for JL24 type printed board

Technical Field

The invention belongs to the technical field of connectors, and particularly relates to a rectangular connector for a JL24 type printed board.

Background

In the conventional JL24 type rectangular connector, the connector is latched to the receptacle only by the insertion of the male pin, and the connector is easily pulled out and separated as shown in fig. 1-2.

When the connector is assembled in a narrow space, the hook groove is firstly tilted to separate the connector plug from the socket, and the plug is upwards pulled up to separate the hook from the hook groove, so that the operation is very inconvenient, other components and parts are easily touched by mistake or hands are easily injured, and the trouble is brought to the replacement or separation of the connector plug; after the multiple separation operations, the hook groove and the hook can be abraded, so that the locking mechanism is slipped and cannot be locked, and the service life of the connector is shortened.

Disclosure of Invention

The object of the present invention is to provide a rectangular connector for JL24 type printed board, which can improve the separation operability, fastening connection reliability and life span of the connector locking mechanism without degrading the locking performance.

In order to realize the purpose, the invention adopts the technical scheme that: a rectangular connector for a JL24 type printed board comprises a plug and a socket, wherein the plug is provided with a jack, the socket is provided with a contact pin, a locking structure is arranged between the plug and the socket and comprises a screw, and the front end of the screw is connected with a socket base through a threaded screw sleeve; the screw penetrates through the mounting holes at two ends of the plug base, and the nut of the screw faces one side of the plug; an elastic washer and a flat washer are arranged between the screw cap of the screw and the plug.

Furthermore, a limiting mechanism is arranged between the screw and the plug base.

Furthermore, the limiting mechanism comprises an inverted cone hanging table arranged on the screw and a limiting table arranged in the mounting hole of the plug base; the inverted cone hanging platform is matched with the limiting platform.

Furthermore, two ends of the plug and the socket are respectively provided with a locking structure.

Further, the threaded screw sleeve is a positioning screw sleeve.

The invention has the beneficial effects that:

1. the invention can improve the separation operability and the fastening connection reliability of the connector locking mechanism under the condition of not reducing the locking performance; meanwhile, the locking structure in the device enables the screw, the elastic washer and the flat washer to be always installed on the base and not to fall off, the screw, the elastic washer and the flat washer are only required to be directly used during installation, fastening parts do not need to be found again, and the installation and the use are more convenient; and the locking mechanism is convenient to separate by adopting threaded connection, the connection reliability is high, the damage is not easy to damage, and the service life is long.

2. According to the invention, the inverted cone hanging table is designed on the screw, the limit table is also arranged in the plug base, when the screw is pushed out, the limit table is opened to prevent the screw from completely falling off, so that the screw, the elastic washer and the flat washer can not be separated from the base, and the screw can be directly used without searching for parts when being reused next time, thereby facilitating the installation operation.

Detailed Description

The following detailed description of the present invention is given for the purpose of better understanding technical solutions of the present invention by those skilled in the art, and the present description is only exemplary and explanatory and should not be construed as limiting the scope of the present invention in any way.

As shown in fig. 1 to 4, the specific structure of the present invention is: a rectangular connector for a JL24 type printed board comprises a plug 1 and a socket 4, wherein a jack 2 is arranged on the plug 1, a contact pin 5 is arranged on the socket 4, a locking structure 3 is arranged between the plug 1 and the socket 4, the locking structure 3 comprises a screw 6, and the front end of the screw 6 is connected with a socket base 401 through a threaded screw sleeve 9; the screw 6 passes through the mounting holes at the two ends of the plug base 101, and the nut of the screw 6 faces to the plug side; an elastic washer 8 and a flat washer 7 are arranged between the nut of the screw 6 and the plug 1.

In order to prevent the screw 6 from being completely removed after being pushed out, a limiting mechanism 10 is arranged between the screw 6 and the plug base 101.

In order to further prevent the screw 6 from completely disengaging, the limiting mechanism 10 comprises an inverted cone hanging table 11 arranged on the screw 6 and a limiting table 12 arranged in a mounting hole of the plug base 101; the inverted cone hanging table 11 is matched with the limiting table 12.

Preferably, the plug 1 and the socket 4 are provided with a locking structure 3 at each end.

Preferably, the threaded insert 9 is a positioning insert. .

When the connector is inserted, firstly, the positioning threaded sleeve is pressed into the socket base as an insert; secondly, the contact pin and the jack are arranged in the base of the plug and the socket; thirdly, the elastic washer and the flat washer are arranged on the screw, and the screw is forcibly pressed into the mounting hole of the plug base by using a tool or equipment; fourthly, the plug and the socket are preliminarily inserted in a mutual insertion mode, so that the contact pin part enters the jack; and fifthly, screwing the screw into the positioning threaded sleeve by using a screwdriver, and tightening the plug and the socket by rotating the screw so as to lock the connector.

When the connector is separated, in the first step, the screw is screwed out of the positioning threaded sleeve by using the screwdriver, and in the second step, the plug is pulled up, so that the contact pin is separated from the jack, and the connector plug is separated from the socket.
