Camera module
A camera module comprises: a first body comprising a lens; a second body coupled to the first body; and a printed circuit board disposed between the first body and the second body. The first body comprises a first guide protruding downward and comprising a first protrusion. The printed circuit board comprises a first guide hole to which the first protrusion is coupled. The first guide is soldered to the first guide hole.
1 . A camera module comprising:
a first body comprising a lens;
a second body coupled to the first body; and
a printed circuit board disposed between the first body and the second body, wherein the first body comprises a first guide protruding downward and comprising a first projection, and
wherein the printed circuit board comprises a first guide hole to which the first projection is coupled,
wherein the first guide is soldered to the first guide hole,
wherein the first body includes a second protrusion projecting downwardly and contacting a top surface of the printed circuit board,
wherein an escape groove is disposed between the second protrusion and the first guide, which is more recessed than in other areas, and
wherein at least a portion of a solder paste is disposed in the escape groove.
2 . The camera module of claim 1 , wherein the first projection includes a first region having a first diameter and a second region having a second diameter smaller than the first diameter, and a region between the first region and the second region is disposed on an inner side of the first guide hole.
3 . The camera module of claim 2 , wherein an inclined region is disposed between the first region and the second region.
4 . The camera module of claim 1 , wherein the first guide and the first guide hole each are provided in plurality, and disposed in each corner region of the first body and the printed circuit board.
5 . The camera module of claim 1 , wherein the first body includes a second guide projecting downwardly and having an engagement groove formed in its center, and the second body includes a third guide projecting upwardly and engaging the second guide.
6 . The camera module of claim 5 , wherein a second guide hole is disposed on the printed circuit board facing the second guide and the third guide in which the second guide or the third guide is engaged.
7 . The camera module of claim 5 , wherein the second guide is disposed between a plurality of adjacent first guides.
8 . The camera module of claim 5 , comprising a reinforcement portion connecting a side plate of the second body and the third guide.
9 . The camera module of claim 1 , wherein an epoxy is disposed between the lower surface of the first body and the upper surface of the second body.
10 . The camera module of claim 1 , wherein a ground area for a ground power source is formed outside the first guide hole among an upper and lower surfaces of the printed circuit board.
11 . The camera module of claim 1 , comprising: a first protrusion protruding downward from a lower surface of the first body; and
a first groove formed between the first protrusion and the second protrusion.
12 . The camera module of claim 11 , wherein an inner surface of the first groove is an inclined surface.
13 . The camera module of claim 1 , wherein a lower surface of the first projection is disposed lower than a lower surface of the printed circuit board.
14 . A camera module comprising:
a first body including a top plate and a first side plate projecting downwardly from an edge of the top plate;
a second body including a bottom plate and a second side plate projecting upwardly from an edge of the bottom plate; and
a printed circuit board disposed in a space within the second body, the first body including a first guide projecting downwardly from an edge of the top plate, the printed circuit board including a first guide hole of a ground power source to which the first guide is coupled, and the first guide being soldered to the first guide hole,
wherein the first body includes a second protrusion projecting downwardly and contacting a top surface of the printed circuit board,
wherein an escape groove is disposed between the second protrusion and the first guide, which is more recessed than in other areas, and
wherein at least a portion of a solder paste is disposed in the escape groove.
15 . The camera module of claim 14 , wherein the first guide and the first guide hole each are provided in plurality, and disposed in each corner region of the first body and the printed circuit board.
16 . The camera module of claim 14 , wherein the first body includes a second guide projecting downwardly and having an engagement groove formed in its center, and the second body includes a third guide projecting upwardly and engaging the second guide.
