Detailed Description
Referring to fig. 1 to 3, a preferred embodiment of the utility model discloses an electrical connector, which includes an insulative housing 10, a conductive terminal 20 fixed on the insulative housing, a shielding shell 30 covering the exterior of the insulative housing, and a locking portion 40. The front and rear directions are defined by the arrangement structure of the electrical connector shown in the figure, that is, the socket side is the front and the rear end is the rear, so it can be seen from the figure that the insulating main body 10 is located at the rear side relative to the shielding housing. The locking portions 40 are located at two ends of the insulative housing 10 for locking the mating connector.
The insulating body 10 has a base 11, a tongue 12 protruding from the base 11, and a positioning block 13 located on the base. The conductive terminal 20 has a holding portion held on the insulating body 10, a contact portion 22 extending from one end of the holding portion to the tongue portion and a soldering portion 23 extending from the other end to the outside of the insulating body.
The shielding shell 30 has a first shell 31 and a second shell 32 fixed on the first shell 31, and the first shell 31 and the second shell 32 are fixed together by spot welding. The first housing 31 is fixed on the insulating housing 10, and the first housing 31 has a mating cavity 100 located outside the tongue 12. The rear end of the first casing 31 is provided with at least one elastic arm 310 and a positioning slot 311 located at the front end of the elastic arm, the positioning slot 311 accommodates the positioning block 13, and the second casing 32 is provided with a groove 320 corresponding to the positioning slot 311 and the elastic arm 310.
Referring to fig. 3, the first housing 31 is provided with a pair of elastic arms 310, and in this embodiment, the elastic arms 310 are respectively extended oppositely, so as to facilitate the forming and the force balance of the elastic arms 310 on the positioning block 13. The first housing 31 and the second housing 32 are fixed together, and then the first housing 31 and the second housing 32 are assembled with the insulating body 10. Because the second housing 32 is provided with the groove, before the elastic arm 310 is assembled, the elastic arm 310 tilts upwards to be accommodated in the groove 320, the positioning block 13 is inserted into the positioning groove 311 from back to front, and then the jig rivets the elastic arm 310, so that the elastic arm 310 deforms downwards, and the elastic arm 310 abuts against the rear side of the positioning block 13 to prevent the positioning block 13 from moving backwards, thereby realizing the assembly of the first housing 31, the second housing 32 and the insulating body 10 together. Compared with the prior art, the combination stability of the positioning block 13 and the first shell 31 is greatly improved, and the defect of poor contact is prevented. When the housing 10 is assembled with the housing, the conductive terminals 20 are usually assembled into the housing 10.
Since the first housing 31 is provided with the elastic arm 310 and the elastic arm 310 protrudes into the groove 320 of the second housing 32 before the product assembly is completed, the area of the positioning groove 311 is smaller than that of the groove 320, facilitating the elastic arm 310 to protrude into the groove 320.
Referring to fig. 2 and 3, the insulation body 10 has a first body 14 and a second body 15, and the second body 15 is integrally formed on the first body 14.
The conductive terminal 20 has a first conductive terminal 26 and a second conductive terminal 27, and the first conductive terminal 26 has a first holding portion 261 fixed on the insulative housing 10, a first contact portion 262 extending from one end of the first holding portion to the upper side of the tongue 12, and a first soldering portion 263 extending from the other end of the first holding portion to the outside of the insulative housing 10; the second conductive terminal 27 has a second holding portion 271 fixed on the insulative housing 10, a second contact portion 272 extending from one end of the second holding portion to the lower side of the tongue portion 12, and a second soldering portion 273 extending from the other end of the second holding portion to the outside of the insulative housing 10, wherein the first soldering portion 263 and the second soldering portion 273 are arranged at intervals to prevent signal interference. The contact portion 22 includes the first contact portion 262 and the second contact portion 272; the welding portion 23 includes the first welding portion 263 and the second welding portion 273.
The first housing 14 is provided with a protruding block 16 protruding into the first housing and a bending piece 17 located behind the protruding block 16, and the protruding block 16 and the positioning block 13 are located at the upper and lower sides of the base 11 respectively. The projections 16 are provided in a pair. The first casing 31 is further provided with a first supporting leg 18 at the rear end thereof, and the second casing 15 is provided with a second supporting leg 19 at both ends thereof, so as to mount the electrical connector on a circuit board. The bending piece 17 is not bent before the insulating body 10 is assembled with the first housing 31 and the second housing 32, and the bending piece 17 is bent and held at the rear side of the base 11 after the assembly.
The first body 14 and the first and second conductive terminals are integrally formed and fixed together, and the second body 15 is integrally formed on the first body 14, so as to improve the bonding strength and the aesthetic property of the first body 14, the second body 15, the first terminal 26 and the second terminal 27.
In summary, the above is only a preferred embodiment of the present invention, and should not be limited to the scope of the present invention, and all the equivalent changes and modifications made by the claims and the specification of the present invention should still fall within the scope of the present invention.
