DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the utility model. In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Embodiment 1: The specific structure of the utility model is as follows:

[0032] Please refer to the attached Figure 1-7The utility model discloses a waterproof terminal connector with a quick-release structure, comprising a male end connector and a female end connector that can be plugged into each other. The male end connector is a fixed end, and a socket shell 1 is provided on the outside of the male end connector, which laterally surrounds the male end connector. The socket shell 1 has a socket cavity and two buckle holes 11 provided on the socket shell. The socket cavity is used for inserting the female end connector. The socket shell 1, which is installed on one side of the equipment, extends to both ends to form a wing plate 12, and the wing plate 12 is provided with a through hole. The screw passes through the through hole to fix the socket shell 1 to the equipment, and then the socket shell 1 protects the male end connector. (Since the male end connector is a commonly used terminal connector, the male end connector of the utility model is not shown).

[0033] After the female end connector is plugged into the male end connector, the female end connector is buckled with the two buckle holes 11, and a first waterproof structure is formed between the female end connector and the male end connector, and a second waterproof structure is formed between the female end connector and the socket shell 1.

[0034] like Figure 2 As shown, the female end connector includes a female terminal 7, a female terminal fixing shell 3 and an outer coating film 2. The first surface of the female terminal fixing shell 3 is provided with a closed-loop retaining ring 34 and a boss 35 higher than the retaining ring 34 and located in the region of the retaining ring 34. The outer periphery of the retaining ring 34 is a circle of closed rounded rectangular surfaces, and the retaining ring 34 is a rounded rectangular structure. The inner and outer ends of the retaining ring 34 are chamfered.

[0035] The boss 35 has a terminal fixing hole that penetrates both sides of the female terminal fixing shell 3. After the female terminal 7 is fixed in the terminal fixing hole, an outer coating film 2 is formed on the outside of the female terminal fixing shell 3 by injection molding; a circle of right-angle steps is formed at one end edge of the outer coating film 2 after forming. One end of the boss 35 is provided with a foolproof outer convex strip, which is perpendicular to the end face of the boss 35 and has a semicircular structure.

[0036] A closed-loop groove 31 is formed between the boss 35 and the retaining ring 34 , and a circle of steps 36 is provided at the corner between the groove 31 and the boss 35 .

[0037] The boss 35 is covered with a first sealing pad 6, and one side of the first sealing pad 6 abuts against the step 36. The first sealing pad 6 forms the first waterproof structure between the female connector and the male connector. Preferably, the first sealing pad 6 is a silicone sealing pad in the shape of a rounded rectangular structure.

[0038] The outer periphery of the retaining ring 34 is covered with a second sealing gasket 5, one side of which is against the rounded rectangular surface. When the male end connector is inserted into the socket cavity, the edge of the mouth of the socket cavity can press the other side of the second sealing gasket 5, so that the second waterproof structure is formed between the female end connector and the socket shell 1. Figure 2 As shown, the second sealing pad 5 is a rounded rectangular structure pad, and its material is also made of silicone.

[0039] It can be seen from the above two waterproof structures that after the female end connector of the utility model is inserted into the male end connector, two waterproofing is achieved, thereby improving the waterproof effect of the connector and preventing short circuit.

[0040] Embodiment 2:

[0041] The second surface of the female terminal fixing housing 3 is provided with two buckle handles, which are respectively connected to the center of the wide edge of the female terminal fixing housing 3; any buckle handle is set at an angle with the second surface of the terminal fixing housing 3 and the angle is greater than 90 degrees; preferably, the angle is 97 degrees. The buckle handle has a rebound ability and can automatically rebound to its original state after being pushed inward.

[0042] The buckle handle has a triangular buckle head 33 in the middle area of ​​its outward side, and a large handle 32 is provided at the outer end of the buckle handle. The inclined surface of the triangular buckle head 33 is close to the connection of the buckle handle, and the triangular buckle head 33 can be buckled into the buckle hole 11. The outer covering film 2 is provided with a space 21 for the buckle handle to swing.

[0043] When the female end connector is inserted into the male end connector, the inclined surface of the triangular buckle head 33 is pressed against the edge of the socket shell 1, forcing the buckle handle to swing inward at an angle. When the female end connector is fully inserted into the male end connector, the right-angled surface of the triangular buckle head 33 buckles into the buckle hole 11. At this time, the triangular buckle head 33 is buckled, and the female end connector cannot be separated from the male end connector.

[0044] When the female end connector needs to be removed, it is only necessary to press the two large handles 32 at the same time and then pull the female end connector outwards to separate the female end connector from the male end connector.

[0045] The female terminal 7 has a female terminal insulation shell and a terminal array 71. The female terminal insulation shell is provided with an array terminal hole and at least one long hole 72 that passes through both sides of the female terminal insulation shell. The terminal array 71 is fixed to the array terminal hole one by one, and the outer covering film 2 fills the long hole 72. The terminal array 71 is connected to the cable 4. Specifically, the terminal array 71 and the cable 4 are connected together by a welding process. Figure 6 As shown, the opening of the array terminal hole is an open-mouth structure, and the four surfaces of the opening are all congruent trapezoidal surfaces. The array terminal hole with an open-mouth structure is convenient for the terminals to enter.

[0046] like Figure 6As shown, two long holes 72 are provided. The purpose of providing the two long holes 72 is that after the outer covering film 2 is formed, the outer covering film 2 will fill the two long holes 72, so that the female terminal shell and the outer covering film 2 are combined and tightened, and the terminal array 71 is also tightened to avoid the terminal array 71 from loosening after frequent insertion.

[0047] Embodiment 2:

[0048] like Figure 2 As shown, both ends of the table surface of the boss 35 are provided with column holes, and columnar power terminals 8 are fixed in the two column holes. The two power terminals 8 are used to connect to the power supply. The power terminals 8 are hollow to form a socket hole, and the corresponding male end connector is provided with two power terminal columns. The two power terminal columns are plugged into the two power terminals 8 one by one.

[0049] In summary, the male and female connectors of the terminal connector of the utility model adopt a snap-on structure, which can achieve the purpose of rapid disassembly and installation. The terminal connector of the utility model adopts a two-layer waterproof structure, which effectively improves the waterproof effect after the male and female connectors are connected.
