At the same time, the drawings in the following texts express the structural schematics related to the features of the present invention, and do not need to be completely drawn according to the actual size, Explain first.

First, referring to FIG. 1 and FIG. 2, according to the above object, the present invention provides a first preferred embodiment, which is a connector assembly 10 for electrically connecting the electrode strip 21 of the solar cell 20 with a pair of wires 22. . The connector assembly 10 includes an insulating base 100, an insulating upper cover 107, and a pair of conductive terminals 3.

Referring to FIG. 3 , the insulating base 100 can be divided into a middle portion 101 and two ends 104 of the insulating base, and includes a groove portion 11 , a blocking wall 111 and a pair of wire connecting portions 13 . The groove portion 11 has an elongated shape and is formed in the intermediate portion 101 of the insulating base. The blocking wall 111 has a longitudinal direction Y protruding from the bottom 115 of the groove portion. A pair of wire connecting portions 13 are provided at both ends 104 of the insulating base. The wire connecting portion 13 has a tapered clamping portion 137 for guiding the insulating sheath 28 of the wire 22 to enter and clamp, so that the wire connecting portion 13 can firmly hold the wire 22, as shown in FIG. .

Referring to FIG. 1 again, the insulating upper cover 107 is placed on the insulating base 100. The length of the insulating cover 107 is approximately equal to or slightly smaller than the length of the middle portion 101 of the insulating base, and is slightly long. Further, it is also possible to have a plurality of protrusions 109 for engaging the plurality of notches 108 on the insulating base 100.

Referring to FIG. 1 , the insulating base 100 may include a pair of cover bodies 14 for covering a pair of wire connecting portions 13 . Referring to FIGS. 3 and 4, the elastic clamping portion 137 of the wire connecting portion 13 may further include a pair of hooks 139 for being embedded in the pair of groove portions 140 of the cover body 14, so that the wire connecting portion 13 can be combined with the cover body. 14 tightly combined. The hook 139 may be in the shape of an inverted hook or the surface of the hook 139 has a plurality of scores, which is a preferred embodiment.

Referring to FIG. 3 , the insulating base 100 may further include a pair of second openings 19 for the electrode strips 21 of the solar cell to be electrically connected to the conductive terminals 3 . The second opening 19 may be disposed at the side 116 of the groove portion of the insulating base 100, or may be located between the blocking wall 111 and the wire connecting portion 13, and the actual position is not limited.

Referring to FIG. 2 and FIG. 3 again, the conductive terminal 3 may be integrally formed, and has a body 30, a first core engaging end 31 and a second core engaging end 32 at both ends of the positioning body 30. The third core engages the end 33. A pair of conductive terminals 3 are arranged longitudinally and oppositely to the bottom portion 102 of the insulating base. The arrangement of the pair of conductive terminals 3 in the opposite direction means that the first core engaging ends 31 of the conductive terminals 3 are respectively disposed adjacent to the wire connecting portions 13 at both ends of the insulating base 100, so that the first core engaging ends 31 are joined. The core 220 of the wire inserted from the wire connecting portion 13. Further, the second core engaging end 32 of one conductive terminal 3 and the third core engaging end 33 of the other conductive terminal 3 are made to correspond to each other. In this way, a pair of conductive terminals 3 can be completely accommodated in the insulating base 100.

Referring to FIG. 2 and FIG. 3 , an engaging notch 309 can be formed on the body 30 of the conductive terminal 3 . An engaging portion 106 is further disposed on the bottom portion 102 of the insulating base. When the conductive terminal 3 is placed in the insulating base 100, the engaging portion 106 can be embedded in the engaging notch 309, so that the conductive terminal 3 can be tightly coupled with the insulating base 100 to improve the stability of electrical conduction.

Referring to FIG. 2, the first core engaging end 31 may be a hollow cylindrical structure and have a slit to tightly hold the core 220 of the wire. Referring to FIG. 5A, the second core engaging end 32 and the third core engaging end 33 form a bending angle θ with the body 30. For example, the second core engaging end 32 and the third core engaging end 33 and the body 30 have a 90 degree bending angle, which can be directly bent outward from the body 30.

Referring to FIG. 2, the conductive terminal 3 is used to connect the second core engaging end 32 of each conductive terminal 3 to the third core engaging end 33 of the other conductive terminal 3 through the diode 23, thereby achieving electrical conductivity. Turn on. In other words, a diode 23 is first disposed between the second core engaging end 32 of one of the conductive terminals 3 and the third core engaging end 33 of the other conductive terminal 3. Further, the second core engaging end 32 and the third core engaging end 33 are further respectively received with the core 230 of the diode. In the same way, the other diode 23 is configured in the same manner. It should be noted, however, that the connector assembly 10 does not necessarily include the diode 23.

Please refer to Figure 5A. Since the diode is easily displaced due to the influence of external force factors or long-term use, the maintenance cost of the connector component is increased. In order to solve this problem, the present invention proposes that each of the second core engaging end 32 and the third core engaging end 33 can be designed to have a width taper. The first opening 35 has a locking portion 36 at the bottom of the first opening 35. The first opening 35 can guide the core 230 of one diode into the locking portion 36 to prevent the core 230 of the diode from coming loose. In addition, a buffer notch 360 may be further formed at the bottom of the locking portion 36 of the second core engaging end 32 and the third core engaging end 33, and the opening of the first opening 35 may be elastically increased through the buffer notch 360. Big and recovery. The above-mentioned buffer notch 360 may have an inverted fan shape or a parallel groove shape.

Referring to Figures 2 and 5B, since the core 230 of the diode is easily arced at the junction of the second core engaging end 32 and the third core engaging end 33, we further increase the height H33 of the third core engaging end. It is designed to be no larger than the height H111 of the blocking wall, as shown in a partially enlarged view of the section of the base of the 5B edge. Further, the longitudinal distance W33 of the pair of third core engaging ends of the pair of conductive terminals 3 is smaller than the length H111 of the blocking wall of the insulating base 100 to block the leakage of the arc. A resisting wall 110 may be respectively added to both ends of the blocking wall 111. When the pair of conductive terminals 3 are placed on the insulating base 100, the resisting wall 110 can resist the third core engaging end 33, preventing the third core engaging end 33 from swaying back and forth.

Referring to FIGS. 3 and 5B , the insulating base 100 may include at least one pair of fitting hooks 15 protruding from the bottom portion 102 of the insulating base. The fitting hook 15 can be located between the blocking wall 111 and the wire connecting portion 13, and the actual position is not limited. Each of the fitting hooks 15 has a head portion 150 and a stem portion 151, and the width W150 of the head portion is larger than the width W151 of the stem portion. In addition, each of the fitting hooks 15 may further include a pair of L-shaped small fitting hooks 1500. Referring to FIG. 5A together, the body 30 can be provided with a fitting notch 37. The width W37 of the fitting notch is smaller than the width W150 of the head of the fitting hook 15, so that the fitting notch 37 and the fitting hook 15 can be tightly fitted.

In the prior art, due to the electrical conduction or the relationship between the heat generated by the diode itself, it is easy to cause the internal temperature of the connector to be too high, resulting in damage to the connector composition. Referring to FIG. 2, in order to solve this problem, the surface of the conductive terminal 3 is designed to be a pattern 39 having a high and low undulation, or a rough surface. Referring to FIG. 3 together, the exposed surface area of the conductive terminal 3 is at least greater than a quarter of the inner area of the groove portion 11 of the insulating base 100. In this way, the heat dissipation effect inside the connector composition 10 can be increased.

Furthermore, since there are quite a large number of types of solar cells, and the degree of thickness is also inconsistent, it is necessary to design a variety of connector components to cope with, which will increase the manufacturing cost for the connector manufacturer. Referring to FIG. 1, in order to solve the above problems, the present invention can configure at least one jig 60 on the connector composition 10. For the detailed structure of the jig, refer to FIG. 6. The jig 60 may be disposed on the side outer edge 103 of the insulating base, and the clamping width is adjusted according to the thickness of the different solar cells 20. Further, in order to increase the convenience of the clamp 60 for adjusting the clamp width, it may include a fixing member 61 and a movable member 62.

The second tooth portion 65 allows the movable member 62 to move up and down to adjust the nip width.

A joint portion 601 and a slit 602 may be formed between the first tooth portion 64 and the fixing member 61. The first tooth portion 64 is connected to the fixing member 61 through the joint portion 601, so that the first tooth portion 64 is supported by the joint portion 601 as a fulcrum. The elastic deformation causes the first tooth portion 64 and the second tooth portion 65 to be fitted to each other. The first tooth portion 64 and the second tooth portion may be arranged in a single direction as shown in FIG. 6, or may be arranged in a pair. For example, the first tooth portion 64 is disposed on both sides of the accommodation space 63, and The two tooth portions 65 are disposed on both sides of the movable member 62.
