Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a connector housing and a connector with a wide internal space. Background Art

[0002] A connector is a commonly used component in electrical engineering. Its function is to connect circuits on different devices or different modules in a circuit, enabling the flow or transmission of current or signals, and enabling the circuit to achieve a predetermined function. Existing connectors include a connection plug and a connection socket, and their connection method is usually by inserting the connection plug into the connection socket, and the conductive terminals of the connection plug and the conductive terminals of the connection socket are electrically connected.

[0003] In order to increase the number of terminal connections, generally multiple terminals are provided in the terminal module, and multiple terminals need to correspondingly connect multiple wires. When the wires are fully inserted or the wires are thick, the internal space of the connector housing is not sufficient. The crowded wires are not convenient for connection operations and also affect the connection stability. Summary of the Utility Model

[0004] The first object of the utility model is to provide a connector housing with a wide internal space.

[0005] The second object of the utility model is to provide a connector with the above connector housing.

[0006] To achieve the first object of the utility model, the utility model provides a connector housing with a wide internal space. The connector housing includes two width side walls in the width direction and two length side walls in the length direction. The two width side walls and the two length side walls are spaced and connected end to end to form a rectangular frame. The two width side walls and the two length side walls all extend along the insertion direction. The insertion direction, the length direction, and the width direction are perpendicular to each other in pairs. The two width side walls and the two length side walls enclose an internal space. A terminal slot is provided at the front end of the internal space in the insertion direction, and a wire groove is provided at the rear end of the internal space in the insertion direction. The terminal slot communicates with the wire groove. The terminal slot is communicatively provided with an insertion port at the outermost side. The width of the wire receiving inner groove of the wire groove in the width direction is greater than the width of the terminal inner groove of the terminal slot in the width direction.

[0007] As can be seen from the above solution, since the width of the wire groove is greater than the width of the terminal slot, after the terminal module is arranged in the terminal slot, the wires connected thereto can be accommodated in the wire groove. Since the wire groove has a greater width in the width direction, more or thicker wires can be accommodated, and the larger space is also convenient for connection operations and better connection stability.

[0008] A further solution is that the width side walls include a terminal wide side wall located at the terminal slot, a wire receiving wide side wall located at the wire receiving slot, and a transition wide side wall. The transition wide side wall is connected between the terminal wide side wall and the wire receiving wide side wall. The terminal wide side wall and the wire receiving wide side wall extend along the insertion direction, and the transition wide side wall is inclined to the insertion direction.

[0009] As can be seen from the above, through the inclined transition wide side wall, while maintaining the original adaptability of the insertion port size, the expansion of the wire receiving slot can be achieved.

[0010] A further solution is that the length side walls include a terminal long side wall located at the terminal slot and a wire receiving long side wall located at the wire receiving slot. The terminal long side wall and the wire receiving long side wall are connected. The terminal long side wall extends along the insertion direction, and the wire receiving long side wall is inclined to the insertion direction; the length of the inner wire receiving slot of the wire receiving slot in the length direction is less than the length of the inner terminal slot of the terminal slot in the length direction.

[0011] As can be seen from the above, by inclining the wire receiving long side wall to the insertion direction and reducing the length of the wire receiving slot, the wires are gathered into a bundle.

[0012] A further solution is that the outer width of the wire receiving between the two wire receiving wide side walls is greater than the outer width of the terminals between the two terminal wide side walls, and a finger recess is formed on the outer side of the transition wide side wall.

[0013] As can be seen from the above, by arranging the finger recess, it is convenient for the user to perform insertion and extraction operations.

[0014] A further solution is that the connector housing includes a top wall, and the top wall is connected to the two width side walls and the two length side walls in a closed manner.

[0015] A further solution is that the length side wall is provided with a side lead opening.

[0016] A further solution is that the connector housing includes a top wall, the top wall is connected to the two width side walls and the two length side walls, and the top wall is provided with a top lead opening.

[0017] A further solution is that the length side wall is provided with a side lead opening.

[0018] A further solution is that the length side wall is provided with a side lead opening.

[0019] As can be seen from the above, the connector housing can not only be arranged in a closed manner, but also form lead openings at the top or side, thereby improving the diversity of lead directions.

[0020] To achieve the second object of the present invention, the present invention provides a connector, including a connection terminal and the connector housing of the above solution, and the connection terminal is arranged in the terminal slot. Description of the Drawings

[0027] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. Specific embodiments

[0028] The first embodiment of the connector and the connector housing:

[0029] Referring to Figures 1 to 3 , the connector includes a connection terminal 21 and a connector housing 1. The connector housing 1 includes two width side walls 11 located in the width direction Y and two length side walls 12 located in the length direction X. The two width side walls 11 and the two length side walls 12 are spaced apart and connected end to end to form a rectangular frame. The two width side walls 11 and the two length side walls 12 all extend along the insertion direction Z. The insertion direction Z, the length direction X, and the width direction Y are perpendicular to each other in pairs. The two width side walls 11 and the two length side walls 12 enclose an internal space 10. The internal space 10 is provided with a terminal groove 101 at the front end in the insertion direction Z and a wire receiving groove 102 at the rear end in the insertion direction Z. The terminal groove 101 is communicated with the wire receiving groove 102. The terminal groove 101 is communicated with an insertion port 103 at the outermost side. The connection terminal 21 is arranged in the terminal groove 101.

[0030] The width side wall 11 includes a terminal width side wall 111 located at the terminal groove 101, a wire receiving width side wall 113 located at the wire receiving groove 102, and a transition width side wall 112. The transition width side wall 112 is connected between the terminal width side wall 111 and the wire receiving width side wall 113. The terminal width side wall 111 and the wire receiving width side wall 113 extend along the insertion direction Z. The transition width side wall 112 is inclined to the insertion direction Z.

[0031] The width L1 of the wire receiving inner groove of the wire receiving groove 102 in the width direction Y is the width between the opposite inner walls of the wire receiving groove 102 in the width direction Y. The width L2 of the terminal inner groove of the terminal groove 101 in the width direction Y is the width between the opposite inner walls of the terminal groove 101 in the width direction Y. The width L1 of the wire receiving inner groove of the wire receiving groove 102 in the width direction Y is greater than the width L2 of the terminal inner groove of the terminal groove 101 in the width direction Y.

[0032] The outer width of the wire receiving between the two wire receiving wide side walls 113 is the width distance between the outer walls of the two wire receiving wide side walls. The outer width of the terminal between the two terminal wide side walls 111 is the width distance between the outer walls of the two terminal wide side walls. The outer width of the wire receiving between the two wire receiving wide side walls 113 is greater than the outer width of the terminal between the two terminal wide side walls 111. A buckle concave portion 114 is formed on the outer side of the transition wide side wall 112. The buckle concave portion 114 is used for the user to hold with the hand for easy installation and disassembly operations.

[0033] The length side wall 12 includes a terminal long side wall 121 located at the terminal groove 101 and a wire receiving long side wall 122 located at the wire receiving groove 102. The terminal long side wall 121 and the wire receiving long side wall 122 are connected. The terminal long side wall 121 extends along the insertion direction Z, and the wire receiving long side wall 122 is inclined to the insertion direction Z.

[0034] The length L3 of the wire receiving inner groove of the wire receiving groove 102 in the length direction X is the length between the opposite inner walls of the wire receiving groove 102 in the length direction X. The length L4 of the terminal inner groove of the terminal groove 101 in the length direction X is the length between the opposite inner walls of the terminal groove 101 in the length direction X. The length L3 of the wire receiving inner groove of the wire receiving groove 102 in the length direction X is less than the length L4 of the terminal inner groove of the terminal groove 101 in the length direction X.

[0035] The connector housing 1 includes a top wall 13. The top wall 13 is connected to the two width side walls 11 and the two length side walls 12. The top wall 13 is provided with a top lead opening 131. A sleeve 22 is provided at the top lead opening 131. The connecting terminal 21 is provided with a plurality of terminals. A plurality of wires are respectively connected to the plurality of terminals. The wires can pass through the sleeve 22. Since the width L1 of the wire receiving inner groove of the wire receiving groove 102 is greater than the width L2 of the inner groove of the terminal groove 101, by arranging the larger wire receiving groove 102, the wires have more arrangement space and operation space.

[0036] The second embodiment of the connector housing:

[0037] Refer to Figure 4 , on the basis of the design of the first embodiment, the connector housing 31 can be in a semi-closed design, that is, the top wall 311 is connected to the two width side walls and the two length side walls in a closed manner. By connecting the two ends of the wire to different terminals, the functions of line jumper or transformation can be realized.

[0038] Third Embodiment of the Connector Housing:

[0039] Refer to Figure 5 , based on the design of the second embodiment, the top wall 311 of the connector housing 32 is enclosedly connected to two width side walls and two length side walls, and side lead openings 321 are provided on the length side walls.

[0040] Fourth Embodiment of the Connector Housing:

[0041] Refer to Figure 5 , based on the designs of the first and third embodiments, a top lead opening 332 is provided on the top wall 321 of the connector housing 33, and side lead openings 334 are provided on the length side walls 333 of the connector housing 33.

[0042] As can be seen from the above, since the width of the wire groove is greater than the width of the terminal groove, after the terminal module is arranged in the terminal groove, the wires connected thereto can be accommodated in the wire groove. Because the wire groove has a greater width in the width direction, more or thicker wire materials can be accommodated, and the larger space also facilitates the connection operation and provides better connection stability.
