[0002] Circuit board cable connectors can quickly and flexibly connect cables to circuit boards. They are the most commonly used component types for internal and external connections of electronic equipment. They have a wide range of applications, and their structural forms vary with the application environment. Fence-type circuit board cable connectors are a common structural form. In the prior art, the structure of circuit board cable connectors is to separate multiple adjacently arranged conductor components with multiple fence-shaped insulating plastic plates to form multiple mutually insulated connection points with different potentials. The wiring methods are diversified, and wires with O-type and Y-type terminals can be connected, or wires can be directly connected. There are two ways to directly connect wires: stripping only and stripping the bare wire end with a bend ring. Among them, the O-type terminal or the bare wire end bend ring has a strong ability to resist the tensile stress applied to the wire. When the fence-type PCB cable connector is used for the Y-type terminal or the straight bare wire that is only stripped, the screw is partially withdrawn for connection. When connecting the O-type terminal and the wire end bend ring, the screw is completely withdrawn, and then the screw is inserted into the O-type terminal or the bend ring for connection. The circuit board cable connector in the prior art is an open type. This open structure has poor protection against foreign objects and is prone to accumulation of pollutants such as moisture and dust, resulting in connection failure. It is also easy for conductive foreign objects to enter, resulting in accidents such as short circuits or electric shocks. Summary of the invention

[0030] Example 1

[0031] like Figure 1 to Figure 17 As shown, a circuit board cable connector with a multifunctional protective cover of the present invention comprises an insulating base 10, the insulating base 10 comprises at least one first bottom plate 17 and at least two baffles 9, the baffles 9 are vertically and spaced apart on the first bottom plate 17, a conductive cavity 8 is respectively arranged between any two adjacent baffles 9, any first bottom plate 17 is provided with a first through hole 18, any conductive cavity 8 is provided with a conductive welding pin 5 and a combination screw 3, the pin of the conductive welding pin 5 passes downward through the first through hole 18, the conductive welding pin 5 is provided with a threaded hole 4, and the combination screw 3 is arranged in the threaded hole 4,

[0032] A protective cover 1 is arranged on the insulating base 10, and the protective cover 1 is elastic. The protective cover 1 includes a second bottom plate 15 and two side plates 16. The two side plates 16 are respectively arranged on the front and rear sides of the second bottom plate 15. Two card slots 2 are vertically arranged in any side plate 16. The left and right sides of the second bottom plate 15 are respectively connected to two rotating shafts 13. Two second through holes 19 are arranged on the sides of the leftmost baffle plate 9 and the rightmost baffle plate 9. The baffle plate 9 is elastic, and the rotating shafts 13 are respectively inserted into the second through holes 19.

[0033] Preferably, the inner side wall of the conductive soldering pin 5 is provided with barbs 12 .

[0034] Preferably, the protective cover 1 is provided with a third through hole 21 corresponding to the conductive cavity 8 .

[0035] Preferably, the inner side surfaces of the leftmost baffle plate 9 and the rightmost baffle plate 9 are each provided with two first demolding grooves 6, any one of the first demolding grooves 6 is provided with a first opening facing upwards, and the two first demolding grooves 6 are respectively connected to the two first through holes 18, and the outer side surface of any one of the baffle plates 9 is provided with two second demolding grooves 11, any one of the second demolding grooves 11 is provided with a second opening facing downwards, and the two second demolding grooves 11 are respectively connected to the two second through holes 19.

[0036] Preferably, a first rotation damping structure is provided between the rotating shaft 13 and the second through hole 19 .

[0037] Preferably, the left and right sides of the second bottom plate 15 each have a protrusion 14, and the two upper corners of the leftmost baffle 9 and the rightmost baffle 9 are both set as rounded corners 20, and the protrusion 14 and the rounded corners 20 constitute a second rotation damping structure.

[0038] Specifically, the insulating base 10, the conductive welding pin 5, the combined screw 3, the first rotation damping structure and the second rotation damping structure in this embodiment all adopt well-known solutions in the prior art, which are well known to those skilled in the art and will not be described in detail here.

[0039] The working principle of this embodiment:

[0040] Insert the needle tip of the conductive solder pin 5 into the soldering hole of the circuit board 24, and form a stable conductive connection between the conductive solder pin 5 and the circuit board 24 after soldering. The combination screw 3 is screwed into the threaded hole 4 to generate pressure between the screw square pad and the conductive solder pin 5 surface to clamp the wire or the end of the connecting wire placed between the combination screw 3 and the conductive solder pin 5, so as to generate a stable conductive connection between the conductive solder pin 5 and the wire, and combine with the above-mentioned solder to form a stable and easily removable conductive connection between the circuit board 24 and the wire. The barbs 12 on the conductive solder pin 5 can allow the conductive solder pin 5 to hook the insulating base 3 so that it is not easy to fall off.

[0041] The protective cover 1 is used to enhance the protective capability of the connector. The protective cover 1 is inserted into the second through hole 19 on the insulating base 10 through the rotating shaft 13. The protective cover 1 can be opened and closed by rotating around two coaxial rotating shafts 13 on the front or rear side. The protective cover 1 can be opened and closed from the front or from the rear. When opening and closing, because there are always two sets of coaxial rotating shafts 13 inserted in the second through hole 19, the protective cover 1 will not fall off the insulating base 10 and is not easily lost.

[0042] like Fig.12As shown, a first rotation damping structure is arranged between the rotating shaft 13 and the second through hole 19, and the protrusion 14 and the rounded corner 20 of the insulating base 10 constitute a second rotation damping structure, so that when the protective cover 1 is opened to a certain angle, damping begins to be generated. This damping can help the protective cover 1 stay at a certain angle and produce an opening and closing feel.

[0043] The card slot 2 on the protective cover 1 makes the protective cover 1 elastic. When installing the protective cover 1, the protective cover 1 is deformed concavely to insert the rotating shaft 13 into the second through hole 19. When removing the protective cover 1, the protective cover 1 is deformed convexly to remove the rotating shaft 13 from the second through hole 19. Fig.16 As shown, when wiring is performed in a specific environment, the protective cover 1 can be completely removed, and the protective cover 1 can be installed after the cables are connected.

[0044] like Figure 3 and Fig.17 As shown, when connecting a Y-type terminal or a straight bare wire, since the protective cover 1 is provided with a third through hole 21, it is not necessary to rotate and open the protective cover 1, and the screwdriver 22 can be inserted into the third through hole 21 to loosen the combination screw 3 for quick wiring.

[0045] The protective cover 1 can be opened and closed from either side. When opening and closing, one side of the protective cover 1 is pulled and the other side of the rotating shaft 13 is rotated as the axis. In this way, the O-type terminal 23 or the bare wire bending ring can be connected from either side without removing the protective cover 1.

[0046] like Figure 5 As shown, the second through hole 19 is provided with a first demolding groove 6 and a second demolding groove 11 in the upper and lower directions respectively, so that a slider is not used during mold manufacturing, which simplifies the mold manufacturing and production maintenance process, improves production efficiency and reduces costs.

[0047] The present invention can not only enhance the protection capability of the cable connector against foreign matter, but also maintain the advantages of simple structure and easy manufacturing, thereby saving product manufacturing cost and mold development cost.
