Description
Technical Field
The utility model relates to a connector technical field, concretely relates to public end assembly of connector.
Background
A connector is a device that connects two active devices and is used to transmit current or signals. The main matching fields of the electric connector comprise traffic, communication, network, IT, medical treatment, household appliances and the like, and the development of the connector technology is strongly dragged due to the rapid development of the product technical level and the rapid growth of the market in the matching fields. To date, connectors have been developed into products with various categories, various specifications, various structural styles, fine professional directions, obvious industrial characteristics, and standardized standard systems. The existing connector comprises a male end assembly and a female end assembly, the male end assembly comprises a needle seat and a plurality of contact pins arranged on the needle seat, the structural design of the existing male end assembly is unreasonable, the contact pins are easy to wear, and the contact pins are easy to loosen and even fall off, so that the male end assembly of the connector has the defects of unreliable performance, unreliable connection and short service life.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance is reliable, connect reliable, long service life's public end assembly of connector.
In order to realize the above purpose, the utility model discloses a public end assembly of connector, set up the contact pin on the needle file including needle file, a plurality of interval arrangement, the cross sectional shape of contact pin be the square, the one end of contact pin has the first grafting portion that is connected with female terminal, the other end of contact pin have extend outside the needle file and the second grafting portion that is connected with the circuit board, and correspond four arriss departments on the middle part of contact pin and be provided with a recess that is rectangular shape respectively, the contact pin on correspond each recess punishment and do not be provided with the bar lug, each recess, each bar lug block respectively on the needle file, and constitute the spacing cooperation of needle file and contact pin.
The beneficial effect of above-mentioned structure is: the strip-shaped groove and the strip-shaped convex block are arranged on the contact pin, the contact pin adopting the structural design is not easy to wear, and the needle seat is mutually fused with the groove and the strip-shaped convex block, so that the connection between the contact pin and the needle seat is more compact, the contact pin is not easy to rotate and loosen, and the male terminal assembly has the advantages of simple structure, stable and reliable performance, reliable connection and long service life.
Particularly, a foolproof limiting column is arranged on one side of the bottom wall of the needle seat corresponding to the second insertion part. The pin base is provided with a fool-proof limit post matched with the circuit board, and the fool-proof limit post can play a fool-proof role, so that the reverse insertion of the male end assembly and the circuit board can be avoided.
Particularly, a clamping block is arranged on the needle base, a guide inclined plane is arranged on one side of the clamping block, and a limiting plane is arranged on the other side of the clamping block. When the needle seat is inserted into the female rubber shell, the clamping block can be clamped on the female rubber shell, so that the needle seat and the female rubber shell can be assembled conveniently, and the assembly efficiency of the male end assembly can be improved.

Detailed Description
As shown in fig. 1 and 2, the embodiment of the utility model provides a public end assembly of connector, including needle file 10, a plurality of interval arrangement set up the contact pin 11 on needle file 10, the cross sectional shape of contact pin 11 be the square, the one end of contact pin 11 has the first grafting portion 111 that is connected with female terminal, the other end of contact pin 11 have extend outside needle file 10 and the second grafting portion 112 that is connected with the circuit board, and correspond four arris departments on the middle part of contact pin 11 and be provided with a recess 113 that is rectangular shape respectively, contact pin 11 on correspond each recess 113 punishment and be provided with bar lug 114 respectively, each recess 113, each bar lug 114 block respectively on needle file 10, and constitute the spacing cooperation of needle file 10 and contact pin 11. A foolproof limiting column 12 is arranged on one side of the bottom wall of the needle base 10 corresponding to the second insertion part 112. The pin base is provided with a fool-proof limit post matched with the circuit board, and the fool-proof limit post can play a fool-proof role, so that the reverse insertion of the male end assembly and the circuit board can be avoided. A fixture block 13 is arranged on the needle base 10, a guide inclined plane 131 is arranged on one side of the fixture block 13, and a limit plane 132 is arranged on the other side of the fixture block 13. When the needle seat is inserted into the female rubber shell, the clamping block can be clamped on the female rubber shell, so that the needle seat and the female rubber shell can be assembled conveniently, and the assembly efficiency of the male end assembly can be improved. The guide plane can play the guide effect to the masterbatch shell, can reduce the insertion force of needle file to in the needle file of being convenient for can be for light insertion masterbatch shell, spacing plane can increase the withdrawal force of needle file, can guarantee that the connection of needle file and masterbatch shell is compacter.
The strip-shaped groove and the strip-shaped convex block are arranged on the contact pin, the contact pin adopting the structural design is not easy to wear, and the needle seat is mutually fused with the groove and the strip-shaped convex block, so that the connection between the contact pin and the needle seat is more compact, the contact pin is not easy to rotate and loosen, and the male terminal assembly has the advantages of simple structure, stable and reliable performance, reliable connection and long service life.
