Detailed Description

Referring to fig. 1 and 2, a plug connector 100 according to a preferred embodiment of the present invention includes: the module comprises an insulating body 10, a shell 20 fixed on the insulating body, a terminal module 30, a locking piece 40 and a circuit board 50. The housing 20 is fixed on the insulating body 10, and the housing 20 has an accommodating space 200 for inserting the mating connector, and the terminal module 30 is disposed in the accommodating space 200, the latch 40 is located at a pair of latch arms 41 at two ends of the terminal module 30 and a fixing portion 42 connected to the pair of latch arms, and the latch arms 41 and the fixing portion 42 are integrally connected, the latch arms 41 protrude into the accommodating space 200, and the latch 40 latches the mating connector to maintain the stability of the mating of the plug connector and the mating connector.

The terminal module 30 includes a body 31 located in the accommodating space 200 and a terminal 32 integrally formed on the body, and a positioning groove 33 is formed on the outer side of the body to be matched with a rib of the housing (not shown), so that the terminal module can be conveniently inserted into the housing 20, and meanwhile, the positioning function is realized, and the matching stability is increased; the terminal 32 has a holding portion 34 fixed on the body 31, a contact portion 35 protruding into the receiving space, and a soldering portion 36 extending therefrom.

As shown in fig. 2 to 6, the holding portion 34 of at least one terminal 32 has a first arm portion 341 and a second arm portion 342 coupled to the body 31, the first arm portion 341 and the second arm portion 342 are disposed in a staggered manner, and the contact portion 35 is located at the ends of the first arm portion 341 and the second arm portion 342. In the present embodiment, only some of the terminals 32 are provided with the first arm portions 341 and the second arm portions 342, but it is needless to say that the first arm portions 341 and the second arm portions 342 may be provided in all of the terminals 32, and the first arm portions 341 and the second arm portions 342 of the terminals 32 may be provided in a staggered manner, so that the coupling strength between the first arm portions 341 and the second arm portions 342 and the main body 31 is increased, the holding force between the terminals 32 and the main body 31 is increased, the coupling strength between the two is increased, and the entry of a medium such as water into the plug connector can be prevented.

At least one terminal 32 is provided with a pair of connecting arms 343 extending rearward from the holding portion 34, and the connecting arms are disposed opposite to each other in the vertical direction to form a channel 344, and the soldering legs 36 are located at the ends of the connecting arms 343. The circuit board 50 is inserted into the channel 344 between the connection arms 343. The holding portion 34 is provided with a through hole 345, and the through hole 345 is combined with the body 31 to increase the combination strength of the terminal 32 and the body 31.

Referring to fig. 4, in the present embodiment, the body 31 has a front end surface 310, and when viewed from top to bottom, a downward projection width H of a joint of the first arm portion 341, the second arm portion 342 and the front end surface 310 is greater than a width H of the first arm portion 341 or the second arm portion 342. Of course, the distance H between the two outermost ends of the projected width may be considered to be not less than the sum 2H of the widths of the first arm portion and the second arm portion (if the widths of the first arm portion and the second arm portion are different, for example, H and H ', respectively, they may be considered to be H + H'). The utility model increases the bonding strength between the first arm 341 and the second arm 342 and the body 31, and prevents the first arm and the second arm from being too close to each other to affect the sealing performance of the bonding with the body 31, and prevents liquid from entering the plug connector.

Referring to fig. 2 again, the housing 20 has an insulating housing 21 and a metal housing 22 covering the insulating housing 21, and the insulating housing 21 is combined with the terminal module 30 and the insulating body 10; the insulative housing 21 has slots 23 at both ends, and the pair of latch arms 41 are located within the slots 23.

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.
