And in the closed state, the latch 23 of the cover 2 cooperates with the block m on the insulating case, thereby ensuring that the shame 2 is reliably held in the closed state. In this embodiment, due to the four The configuration of the terminal assembly 4 is basically the same, so the following mainly describes one of them as an example. The terminal assembly includes a metal housing 3 and first, second, and third elastic terminals 41 assembled on the metal housing 3, 42, 43, the metal casing 3 and the elastic terminal 4, 42, 43 can be formed by stamping and processing. Referring to the fourth figure, the metal casing 3 includes a longitudinally extending bottom plate 31, and the bottom plate 31. The riser 32, which extends vertically upward from the rear end, and the top plate 33 which extends further rearward from the top of the riser 32. The bottom plate 31 has a pair of first side walls 34 extending vertically upward and longitudinally rearwardly on the lateral sides of the front portion, and a pair of second side walls 35 extending longitudinally rearward from the lateral sides of the lower portion of the g plate 32. a first slot 341 is defined in a vertical direction at a top of the first sidewall 34; a second slot 342 is disposed between the rear portion of the first sidewall 34 and the bottom plate 31; and is longitudinally disposed on the second sidewall 35 A third card slot 351 is opened. The first, second, and third card slots 341, 342, and 351 are substantially identical in configuration, and are respectively used to cooperate with the first, second, and third elastic terminals 41, 42, and 43, which will be further described later. Each of the grooves 341, 342, and 351 is narrow at the opening position, but gradually widens toward the bottom. The board 32 extends further obliquely upwardly at the junction with the top plate 33 and is formed with two guiding grooves 322, 323'. The top plate 33 defines an opening 332 at the junction with the vertical plate 32, with respect to the guiding slot and 201012013 opening σ The side will be described in detail later. The bottom plate 3 of the metal casing 3 and the top plate 33 are in contact with the first, second, and third elastic terminals 4, and the first, second, and third contact regions 3, 33, respectively. A friction-enhancing structure is provided to enhance the static force of the contact object and the contact property. In this implementation, the county reinforcement structure is provided in a plurality of trenches in the contact area, and those skilled in the art can also easily think that the structures can also be complex bumps or stripes disposed in the contact area. Or the entire contact area is treated as a matte surface, and the structures can also achieve effects similar to those of the trenches in this embodiment. © As shown in the fourth figure, in the present embodiment, the first, second, and third elastic terminals 4, 42 and 43 are configured to be touched by the m-terminal terminal 41_. The first elastic terminal 41 can be formed by sheet metal forming and further formed. It includes a first-holding portion 4n connected to the metal shell 3, a first joint that is positively bent and extended from the first holding portion 411 to be in contact with the metal casing 3 or the corresponding electrical connecting member and elastically pressed 412, and a first release portion 413 formed by the forward contact and extending from the first contact 4 412 for external force pressing to release the elastic contact pressure of the first contact 邙 412. The forward bending referred to herein refers to the f-curve in the counterclockwise direction, whereas the 'curved in the clockwise direction will be referred to as the inverse buckling. Of course, and vice versa, the clockwise direction is positive and the counterclockwise direction is reverse. Note that the 疋 applied to the first release portion 413 is a positive force (such as F in the fifth and sixth figures), in order to prevent the positive force from being applied too much or too frequently. As a result, the terminal is deformed, and a curved portion 414 is provided between the forward f-curved portion after the '"holding portion 411 and the first contact portion 412, thereby increasing the anti-f strength of the terminal. In addition, the first release 413 also has a reversed fold portion f to facilitate the operator's application of force. The first holding portion 413 vertically protrudes from the pair of lugs 415 at the ends on the lateral sides, and is further provided with a laterally extending-to-wing portion 4!6 near the lug for the metal shell Zhao 3 The corresponding card slot 341 is matched. As shown in the fourth figure, during assembly, the first, second, and 201012013 elastic terminals 41, 42, 43 are respectively assembled into the metal casing 3 along the direction of the arrow, that is, the first terminal 41 is vertical. The second and third terminals 42, 43 are grouped in the horizontal direction in the horizontal direction. Correspondingly, the lateral sides of the first, second, and third holding portions 41, 421, 431 are respectively inserted into the first, second, and third card slots 34, 342, 351 to be the first, second, third The terminals 41, 42, 43 are reliably fixed to the metal casing 3.

[Refer to the reference, the __ and the second figure, the respective terminal combinations are respectively grouped into corresponding ones. In the cage, the rear hooks (2) and 122 of the group are respectively engaged with the first side wall 34 and the top plate 33 of the metal casing 3 to ensure that the terminal assembly is reliably received in the insulating housing 1. Between the two adjacent terminal combinations, an electrical connection is made between the electronic component connection and the terminal combination. As shown in the fifth®, the actual electronic component is a two-pole ship 5, and the output wire 6 includes a metal core. The electrical connection of the line 61 'too miscellaneous panels is an electrical conductor 7 having a metal (10)n. In the direction shown, the two copper legs 51 of the diode 5 are respectively inserted into the third contact portion 432 of the third elastic terminal 43 and the metal shell 2 through the guide groove 1 of the adjacent terminal combination guide groove 1 The contact area Π is held by the third contact portion 432 and held at the position; the lead metal core 61 is inserted into the second contact portion 422 of the second elastic terminal 42 and the metal/the second contact area Between the 331 and being pressed by the second contact portion 422 to maintain the position of the metal ray 71 of the solar material recording wire 7 of the first and second terminals 2010 201012013' - the contact portion 412 and the metal casing 3 The first contact regions 311 are held by the first contact portion 412 and held at this position.

However, for the second and third elastic terminals 42, 43 because it does not have a portion exposed to the outside, it is necessary to insert or take out the output lead 6 and the two φ pole body 5 by means of a tool. The sixth embodiment shows another embodiment of the solar panel connection box of the present invention. The difference from the above embodiment is that the metal core of the solar panel electrical conductor and the metal core of the connection box output conductor are in this embodiment. It is replaced with an electric board 72, 62 having a metal conductive layer on its surface, such as an electric board plated with a gold finger. Of course, other electrical connectors such as conductive terminals and the like can be easily conceived by those skilled in the art. In the embodiment described above, the elastic terminal connected to the solar panel of the terminal of the connection box is at least partially disposed in the insulating housing without any hindrance, so that the operator can press the convex portion without using a tool. The elastic terminal is toggled so that the electrical wires of the solar panel can be easily inserted or removed; in addition, the terminal has the same configuration as the terminal for connecting the two poles and the terminal for connecting the output wires, thereby The versatility of the components is made, thereby simplifying the manufacturing process and reducing the cost; in addition, the contact area on the metal casing is provided with a friction-enhancing structure, which improves the static friction force, thereby enhancing the stability of the component insertion; In addition, the fixing between the terminal and the metal casing and between the metal casing and the insulating casing is fixed by the snap structure, which facilitates assembly and improves the assembly convenience of the components. Of course, the above are all preferred embodiments of the present invention, and those skilled in the art can also change the structure of the above embodiments to implement the present invention. For example, in the above embodiment, the elastic terminal is detachable with respect to the metal housing, but in other embodiments, both may also be 11 201012013 - being integrally formed 'only need to ensure that the first release portion is uninsulated to be placed in the insulation In the housing, the invention can also be realized in the same way; in addition, since the diode is substantially not detached after being connected to the terminal combination, it is also conceivable to directly solder the diode to the metal casing, thereby eliminating the need for The third elastic terminal, but the omission of such a member does not affect the implementation of the present invention. In view of the above, it is to be understood by those skilled in the art that the equivalents of the present invention are intended to be included within the scope of the present invention.
