Description

Technical Field

[0001] This utility model relates to, specifically to, a connector with a secondary protection structure. Background Technology

[0002] Connectors generally refer to electrical connectors, which serve to bridge gaps in a circuit or connect isolated circuits, allowing current to flow and enabling the circuit to perform its intended function.

[0003] In the existing technology, the signal terminals and power terminals of the connector are only provided with one retainer plate that holds the connector on the step of the core. However, if the retainer plate or the core is damaged, it cannot prevent the signal terminals or power terminals from slipping off, which may damage the equipment or even cause a fire.

[0004] Therefore, it is necessary to provide a new technical solution. Utility Model Content

[0005] To address the technical problems existing in the prior art, this utility model discloses a connector with a secondary protection structure, the specific technical solution of which is as follows:

[0006] This utility model provides a connector with a secondary protection structure, including a core, power terminals, signal terminals, a sealing body, and a locking cover.

[0007] Two first connecting holes and two second connecting holes are symmetrically arranged on the first end face of the rubber core. A power terminal is placed in the first connecting hole and a signal terminal is placed in the second connecting hole. The locking cover plate is embedded in the first end face of the rubber core and is located between the end of the power terminal and the sealing body. The locking cover plate locks the power terminal and the signal terminal.

[0008] Furthermore, the locking cover plate includes a panel, a boss, and a connecting plate, and the second connecting hole is provided with an inwardly protruding first step.

[0009] The first surface of the panel is flush with the first end face of the adhesive core and is in contact with the sealing line.

[0010] The protrusions are symmetrically arranged on both sides of the second surface of the panel and directly opposite the first connecting hole. The protrusions extend outward to contact the end of the power terminal.

[0011] The connecting plates are symmetrically arranged on the edge of the second side of the panel and directly opposite the second connecting hole. The connecting plates extend into the second connecting hole and squeeze the signal terminal until it contacts the first step.

[0012] Furthermore, the boss is arc-shaped and fits against the end edge of the power terminal.

[0013] Furthermore, the connecting plate is configured as a straight plate that rests against the inner wall of the second connecting hole.

[0014] Furthermore, the first step is configured with a sloping structure on the side near the locking cover plate, and the end of the connecting plate expands outward along the sloping surface.

[0015] Furthermore, the part of the connecting plate that contacts the slope structure of the first step is configured with a slope shape that is less than the slope of the first step.

[0016] This utility model has the following beneficial effects:

[0017] This utility model provides a connector with a secondary protection structure. A locking cover plate provides secondary protection for the signal and power terminals. The end of the connecting plate on the locking cover plate extends into the second connecting hole and expands outward through a sloping structure to form a step supporting the signal terminal. The boss on the locking cover plate is engaged with the end of the power terminal, and a sealing body provides support to the boss and the panel, preventing the power terminal from slipping. By adding the locking cover plate to the existing locking sleeve that holds the signal and power terminals in place, a secondary locking protection effect is achieved, making the protection more effective and secure. This utility model also has other advantages such as simple structure, ingenious design, and convenient operation.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] This utility model discloses a connector with a secondary protection structure, see reference. Figures 1 to 4 The device includes a core 1, a power terminal 2, a signal terminal 3, a sealing body 4, and a locking cover plate 5. Two first connecting holes and two second connecting holes are symmetrically arranged on the first end face of the core 1. The power terminal 2 is placed in the first connecting hole, and the signal terminal 3 is placed in the second connecting hole. The locking cover plate 5 is embedded in the first end face of the core 1. The locking cover plate 5 is located between the end of the power terminal 2 and the sealing body 4, and the locking cover plate 5 locks the power terminal 2 and the signal terminal 3.

[0028] refer to Figures 2 to 4The locking cover 5 includes a panel 51, a boss 52, and a connecting plate 53. A first step 11 protruding inward is provided in the second connecting hole. The first surface of the panel 51 is flush with the first end face of the adhesive core 1 and fits against the sealing body 4. The bosses 52 are symmetrically arranged on both sides of the second surface of the panel 51 and face the first connecting hole. The bosses 52 extend outward to contact the end of the power terminal 2.

[0029] The connecting plates 53 are symmetrically arranged on the edge of the second side of the panel 51 and directly opposite the second connecting hole. The connecting plates 53 extend into the second connecting hole and squeeze the signal terminal until they contact the first step 11.
