Description

Low insertion force type connector
Technical Field
The invention relates to a low insertion force type connector, and belongs to the technical field of connectors.
Background
As the number of contacts of the connector increases, the insertion force and the separation force required for the mating use of the connector also increase, and the insertion and separation operation becomes difficult. Thus, a low Insertion force type connector, such as a known zif (zero Insertion force) connector, is proposed, which does not require a strong force when inserting a connector part and presses contacts against a connection part after inserting the connector part, thereby achieving electrical connection.
Patent document 1 discloses a low insertion force type connector. The low insertion force type connector has a plurality of contacts to be brought into contact with terminals of a mating connector, a contact promoting means in the shape of a first cam member, a separating means in the shape of a second cam member, a locking means in the shape of a hook member, and a driving means. The drive means integrally drives the contact promoting means as well as a separating means and a locking means.
Patent document 1 discloses: cams (second cam members, i.e., separating means) are formed at both ends of the main body (molded on the shaft by the clip), and hook-shaped members (locking means) are formed outside the diameter-reduced portions; the cam may be integral with the shaft or a separate cam can be used, the hook-shaped element being connected to the shaft as a separate element. It follows that the cam (disengaging means) and the hook-shaped element (locking means) are two distinct entities, integrally formed on the shaft.
Patent document 1: CN1251361C low insertion force type connector.
Disclosure of Invention
To overcome the deficiencies of the prior art, the present invention provides a low insertion force type connector.
The invention is realized by the following technical scheme:
a low insertion force type connector comprises a plug connector and a socket connector which are matched for use, wherein a clamping pin is arranged on the plug connector, a cam shaft is arranged on the socket connector and comprises a cam main body and a driving rod connected with the cam main body, a locking and separating integrated device is arranged on the cam main body and comprises a transmission gear and a hook-shaped element connected with the transmission gear, a convex surface is arranged on the hook-shaped element, and the clamping pin can be connected with the hook-shaped element.
In the low insertion force type connector, the hook-shaped element has a center hole, and the center hole is coaxially arranged with a center hole of a transmission gear, and the transmission gear drives the hook-shaped element to rotate.
The low insertion force type connector has a hook member having a body and a hook portion, the body and hook portion having an included angle of less than 30 °.
In the low insertion force type connector, the joint of the body and the hook part can accommodate the snap pin.
In the low insertion force type connector, two locking and separating integrated devices are respectively arranged on two sides of the cam main body.
The low insertion force type connector is characterized in that a locking screw is further arranged on the socket connector.
The invention achieves the following beneficial effects:
the connector of the invention drives a plurality of contact elements to deflect and deflect along with the rotation of the camshaft in the shell, thus realizing the joint with low insertion force; the cam shaft rotates the lock release integrated device and causes the mating connector to be locked after being pulled into the fully engaged state from the engagement depth before the full engagement, and by this locking, the fully engaged state can be maintained.
The invention integrates the functions of the separating device to the elements of the locking device to form a locking and separating integrated device, thereby eliminating a separate separating device, reducing the number of parts and saving the cost. The original machining precision completely meets the requirements after the functions are integrated, the cost of parts does not need to be increased, the cost for independently machining the cam (separating device) is saved, and the labor cost for assembling the cam and the shaft is saved. Because the functional surface (the convex surface with the separation function) of the cam has higher processing precision, the unit price of the batch processing cost is about 3 yuan, 4 cams are saved by a single connector, the labor cost for assembly is not calculated, the estimated cost of the connector can be reduced by 12 yuan, and compared with the prior art, the cam has prominent substantive characteristics and remarkable progress.

Detailed Description
The invention is further described below. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 to 5, the connector of the present invention includes a plug connector 1 and a receptacle connector 2. The plug connector 1 comprises a clamping pin 1-1 and a plurality of terminals 1-2 which are regularly arranged, and the socket connector 2 comprises a shell 2-1, a cam shaft 2-2, an upper base 2-3, a locking screw 2-4 and a contact element assembly 2-5.
