Detailed Description

The invention is described in detail below with reference to the attached drawing figures:

embodiment one:

please refer to fig. 1 to 4, which illustrate a transmission connector 101 according to the present invention. The transmission connector 101 includes a connection body 10, a first connection portion 30, and a second connection portion 50. The first connection portion 30 and the second connection portion 50 are respectively provided on the connection body 10, and can be electrically connected to a cable 70 and a connector 90, which will be described below.

The particular shape and configuration of the connector body 10 is selected according to the particular application requirements. In this embodiment, the connection body 10 has a substantially plate shape. The connecting body 10 is provided with a first end 10a and a second end 10b along an axial direction. The connecting body 10 is provided with a top wall 10c and a bottom wall 10d at both radial ends. The bottom wall 10d is for supporting the second connecting portion 50. To further enhance retention of the cable 70 to facilitate assembly, the top wall 10c and the bottom wall 10d are adjacent to each other and form a guide slot 18. Accordingly, the guide groove 18 extends in the axial direction of the connection body 10 and is disposed axially opposite to a cable connection portion 32 described below. In this embodiment, to further facilitate the extension of the cable 70, the guide groove 18 is a through groove.

With continued reference to fig. 1 to 4, the first connecting portion 30 is disposed on the first end portion 10a of the connecting body 10 in a protruding manner, and extends along the axial direction of the transmission connector 101. The first connection portion 30 has a cable connection portion 32. The cable connection 32 may hold a cable 70. When the cable 70 is disposed in the axial direction and in the opposite direction, the specific shape and structure of the cable connection portion 32 may be sufficient to keep the cable 70 and the transmission connector 101 as one body. For example, the cable connection portion 32 may be a through hole or a through cavity penetrating along the axial direction of the connection body 10. To facilitate assembly of the cable 70, the cable connector 32 may be a stamped configuration. That is, the cable 70 is preset at the holding position, and the sheet structures on the upper and lower sides of the cable 70 are pressed so that the two sheet structures are close to each other and form the through hole or the through cavity, thereby avoiding the process of laboriously inserting the cable 70 into the corresponding through hole or the through cavity, and easily realizing that the inner peripheral wall of the through hole or the through cavity is abutted against the outer peripheral wall of the cable 70 so as to enhance the holding performance of the cable 70. In this embodiment, the cable connection portion 32 is a through hole. In the present embodiment, the number of the through holes is two for holding the cable 70 including two cables. As a modification, the cable connection portion 32 may be a through groove provided to extend axially therethrough. The through groove may be integrally connected to the cable 70. Of course, the cable connection portion 32 may also be a holding structure such as a buckle (not shown). Correspondingly, the buckle can also abut against the outer peripheral wall of the cable 70 and realize the retaining and limiting function of the cable 70.

Fig. 1 shows a structure in which the first connecting portion 30 is not press-fitted with the cable 70. Referring to fig. 2 to 4, when the first connection portion 30 needs to be connected to the corresponding cable 70, the first connection portion 30 is provided with the cable connection portion 32 in a press-fit manner, so as to achieve press-fit with the corresponding cable 70, thereby simplifying the process and improving the stable connection performance. Accordingly, in the present embodiment, the cable connection portion 32 is formed by bending a pair of fins (not shown in fig. 1). That is, in the present embodiment, the cable connection portion 32 is a wire crimp portion.

The second connection portion 50 extends continuously from the connection body 10 and is electrically connectable to the connection body 90. The specific location at which the second connection portion 50 is provided on the connection body 10 is selected according to the specific connection needs. In the present embodiment, the second connection portion 50 is provided on the bottom wall 10d of the connection body 10 in order to make full use of a specific installation space. More specifically, the second connection portion 50 is disposed along a lateral extension of the transmission connection member 101. The specific shape and structure of the second connection portion 50 may be such that connection with the connector 90 described below is achieved. In this embodiment, the second connection portion 50 has a substantially flat plate shape. To facilitate a secure connection with the connector 90, the second connection portion 50 is provided with a mounting through hole 52 provided radially therethrough. The mounting through hole 52 may receive one end of the connection body 90 and be welded integrally with the connection body 90 to enhance the stable connection performance.

In order to enhance the stability of the transmission connector 101 and facilitate the manufacture, in the present embodiment, the transmission connector 101 is a metal integrated part. More specifically, the transmission connector 101 is formed by bending a single piece of sheet metal, such as by stamping. The material of the transmission connector 101 may be copper. To further obtain a larger current carrying capacity for enhancing the electrical transmission performance, the transmission connection 101 is a bus (english name: bus-bar).
