Description

Technical Field

[0001] This utility model relates to a connector for charging or supplying power, and more particularly to a connector structure with a terminal arrangement. Background Technology

[0002] Existing connectors used in applications such as electric vehicles or high-power charging systems typically include a set of high-current power terminals and multiple signal terminals. The signal terminals are primarily used for handshake, communication, and security detection, such as control pulse signals (CP), proximity detection signals (PP), or CAN bus communication. In existing technology, the signal terminals are often distributed around the two power terminals to reduce connector size and facilitate sharing the mating structure with the power terminals. However, this arrangement has the following drawbacks:

[0003] 1. Signal terminals are susceptible to mechanical damage: During insertion and removal, signal terminals are prone to bending or breaking due to their small size and proximity to any power terminal.

[0004] 2. Decreased reliability: Damage to the signal terminals may lead to handshake or communication failure, which in turn affects charging safety.

[0005] 3. Limited plug-in / plug-out lifespan: The signal terminals lack protective structures, and poor contact or malfunctions are prone to occur after long-term use.

[0006] IV. Miniaturization limitations: Increasing the isolation distance to protect the signal terminals limits the further miniaturization of the connector.

[0007] Therefore, the prior art has not yet provided a terminal arrangement structure that can simultaneously protect signal terminals and ensure electrical reliability in miniaturized charging connectors. Utility Model Content

[0008] The main objective of this invention is to provide a connector structure with a terminal arrangement, which utilizes the distance between the positive and negative power terminals to allow multiple signal terminals to be arranged vertically in the middle, thereby improving the more even distribution of force during male-female mating, thus achieving the purpose of protecting the signal terminals and ensuring electrical reliability.

[0009] To achieve the above objectives, this utility model provides a connector structure with terminal arrangement, including a connecting body, two power terminals, and a signal terminal group; the two power terminals and the signal terminal group are disposed on the connecting body, and the signal terminal group includes a linear array and two symmetrical arrays formed by multiple signal terminals arranged in a linear array. The signal terminals of the linear array are arranged vertically in a line between the two power terminals, while the signal terminals of the symmetrical array are symmetrically arranged on both sides of the signal terminals at the two ends of the linear array.

[0051] To further disclose the features and technical content of this utility model, please refer to the following detailed description and drawings of this utility model. However, the drawings are provided for reference and illustration only and are not intended to limit this utility model.

[0052] Please see Figure 1 and Figure 4 These are exploded perspective views and mating assembly views of the male and female connectors of this utility model. This utility model provides a connector structure with terminal arrangement, which can be applied to a female connector 1 or a male connector 2, so as to facilitate the insertion and connection or separation of the male connector 2 and the female connector 1.

[0053] like Figure 1 and Figure 2As shown, taking the aforementioned female connector 1 as an example, the female connector 1 includes a connecting body 10, and two power terminals 11 and a signal terminal group 12 disposed within the connecting body 10. The connecting body 10 may be a female socket with a socket 100, and the signal terminal group 12 includes a linear array 120 and two symmetrical arrays 121 formed by multiple signal terminals. The two power terminals 11 and the signal terminals are arranged within the socket 100 along the insertion direction of the socket 100. Specifically, the socket 100 of the connecting body 10 may be slightly elliptical, and the two power terminals 11 are disposed within the two ends of the ellipse and spaced apart to reserve a certain gap between them. The signal terminals of the linear array 120 are located between the two power terminals 11.

[0054] like Figure 2 As shown, the signal terminals of the vertical array 120 are a first signal terminal 120a, a second signal terminal 120b, and at least a third signal terminal 120c. The first signal terminal 120a, the second signal terminal 120b, and the third signal terminal 120c are arranged vertically in a row between the two power terminals 11. The first signal terminal 120a is located at one end of the row, the second signal terminal 120b is located at the other end of the row, and the third signal terminal 120c is arranged between the first signal terminal 120a and the second signal terminal 120b to form the row. One of the symmetrical arrays 121 has two fourth signal terminals 121a, and the other symmetrical array 121 has two fifth signal terminals 121b. The two fourth signal terminals 121a are symmetrically arranged diagonally on both sides of the first signal terminal 120a, and the two fifth signal terminals 121b are symmetrically arranged on both sides of the second signal terminal 120b. This arrangement allows most of the signal terminals to be placed in the linear array 120, with only a few used as signal terminals in the symmetrical array 121. Therefore, the two power terminals 11 can protect the signal terminal group 12, and the signal terminal group 12 forms a simplified symmetrical arrangement, ensuring even distribution of force during male-female mating and preventing damage to the signal terminals due to uneven force.

[0055] As described above, the female connector 1 may also have a power plug-in portion 101 on the outside of the two power terminals 11 and a signal plug-in portion 102 on the outside of the signal terminal group 12. The power plug-in portion 101 may be cylindrical, and the signal plug-in portion 102 may be connected to the first signal terminal 120a, the second signal terminal 120b and the third signal terminal 120c of the linear array 120 to form a vertical "I" shape. It may also be further connected to the two fourth signal terminals 121a and the two fifth signal terminals 121b with an expansion portion 102a and 102b respectively, so that the signal plug-in portion 102 further forms an "I" shape.

[0056] Furthermore, such as Figure 1 and Figure 3 As shown, taking the aforementioned male connector 2 as an example, the male connector 2 includes a connecting body 20, and two power terminals 21 and a signal terminal group 22 disposed within the connecting body 20. The connecting body 20 can be a male connector with an insertion end face 200, and the insertion end face 200 has recessed two power insertion portions 201 and a signal insertion portion 202, respectively corresponding to the two power insertion portions 101 and the signal insertion portion 102 of the aforementioned female connector 1. The signal terminal group 22 includes a linear array 220 and two symmetrical arrays 221 formed by multiple signal terminals, and the two power terminals 21 and the signal terminals of the signal terminal group 22 are respectively disposed within the two power insertion portions 201 and the signal insertion portion 202 along the insertion direction of the socket 100. Specifically, as Figure 5 and Figure 6 As shown, the outer shape of the connecting body 20 may be slightly elliptical to fit into the socket 100 of the female connector 1, thereby allowing the power terminal 21 of the male connector 2 to be inserted and connected to the power terminal 11 of the female connector 1, and the signal terminal group 22 of the male connector 2 to be inserted and connected to the signal terminal group 12 of the female connector 1. A female end fastener 13 may be provided on the connecting body 10 of the female connector 1, and a male end fastener 23 may be provided on the connecting body 20 of the male connector 2, so that after insertion and connection, the male end fastener 23 is locked onto the female end fastener 13 to maintain their mating state.

[0057] like Figure 3As shown, the signal terminals of the vertical array 220 are a first signal terminal 220a, a second signal terminal 220b, and at least a third signal terminal 220c. The first signal terminal 220a, the second signal terminal 220b, and the third signal terminal 220c are arranged vertically in a row between the two power terminals 21. The first signal terminal 220a is located at one end of the row, the second signal terminal 220b is located at the other end of the row, and the third signal terminal 220c is arranged between the first signal terminal 220a and the second signal terminal 220b to form the row. One of the symmetrical arrays 221 has two fourth signal terminals 221a, and the other symmetrical array 221 has two fifth signal terminals 221b. The two fourth signal terminals 221a are symmetrically arranged diagonally on both sides of the first signal terminal 220a, and the two fifth signal terminals 221b are symmetrically arranged on both sides of the second signal terminal 220b. This arrangement allows most of the signal terminals to be placed in the linear array 220, with only a few used as signal terminals in the symmetrical array 221. Therefore, the two power terminals 21 can protect the signal terminal group 22, and the signal terminal group 22 forms a simplified symmetrical arrangement, ensuring even distribution of force during male-female mating and preventing damage to the signal terminals due to uneven force.

[0058] As described above, the two power insertion portions 201 of the male connector 2 can each be in the shape of a round hole, and the signal insertion portion 202 can be in the shape of a vertical socket. Furthermore, it can be connected to the two fourth signal terminals 221a and the two fifth signal terminals 221b respectively through an expansion hole 202a and 202b, so that the signal insertion portion 202 can further form an "I"-shaped socket.

[0059] In addition, such as Figure 6 As shown, the expansion portion 102a and expansion hole 202a used to correspond to the first signal terminals 120a and 220a can be designed differently in appearance from the expansion portion 102b and expansion hole 202b corresponding to the second signal terminals 120b and 220b. In this way, it can also serve as a foolproof structure to prevent users from inserting the wrong parts.

[0060] Therefore, through the above-described construction, the connector structure with terminal arrangement of this utility model can be obtained.

[0061] In conclusion, this utility model is a rare and innovative creation that truly achieves the creative purpose described in the above specification and addresses the deficiencies of conventional technology. Furthermore, due to its novelty and progressiveness, it fully meets the requirements for a utility model patent application. Therefore, this application is filed in accordance with the Patent Act to protect the applicant's rights.

[0062] However, the above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Therefore, all equivalent structural changes made using the contents of the present utility model specification and drawings are also included within the scope of the present utility model and are hereby stated.
