Detailed Description

In order to explain technical contents, structural features, implementation principles, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in combination with the embodiments.

As shown in fig. 1 to 5, the present invention discloses an electronic function module casing structure, which comprises a casing 1, a cavity 10 for installing an electronic function module is provided on the casing 1, a plurality of connecting terminals 3 are provided on the casing 1, the connecting terminals 3 comprise soldering terminals 30 for electrically connecting with the electronic function module in the cavity 10 and pin terminals 31 extending out of the casing 1 for electrically connecting with an external device, the soldering terminals 30 of the plurality of connecting terminals 3 are provided with insulating barrier portions 11 therebetween, the height H of the barrier portion 11 is not lower than 1/2 of the height of the soldering terminal 30, in this embodiment, the barrier portion 11 is used for blocking tin connection between two soldering portions adjacent to each other during soldering, so the height of the portion cannot be too low, and too low does not play a role, and through repeated tests, the barrier portion 11 is at least 1/2 of the height of the soldering terminal 30, it is preferable that the upper end of the barrier 11 be maintained substantially flush with the upper end of the weld end 30. Like this, when welding the electronic function module in weld end 30 and the casing 1 together, because the blocking of baffle portion 11, two connecting terminal 3 adjacent each other can not take place the phenomenon of even tin to effectively prevent the short circuit, this has not only improved the yields of product, and operating personnel need not worry moreover and causes even tin, thereby can also effectively improve production efficiency, reduction in labor cost. In addition, the thickness of the baffle 11 is preferably 0.1-1 mm, so that the baffle has the function of insulation and baffle, and does not occupy too much space on the shell 1.
