Description
Technical Field
The invention relates to an electrical box which can realize arbitrary application and layout of an internal signal circuit and an external signal circuit of the electrical box.
Background
In an electrical box of a vehicle, a plurality of connectors are used to conduct a main circuit, and in practical applications, it is also necessary to conduct an internal signal circuit of the electrical box or connect the electrical box with an external signal circuit at the same time.
If the connector used includes only the main circuit and does not include the signal circuit, when the signal circuit needs to be used, as shown in fig. 1 and 2, a connector E dedicated to the signal circuit needs to be added, and at the same time, in addition to the connector mounting portion 501 of the connector for conducting the main circuit, a connector mounting portion 502 dedicated to the signal circuit connector E needs to be added to the electrical box 500, which makes the structure of the electrical box large and complicated, and increases the cost. Therefore, connectors with signal return paths are commonly used on electrical boxes.
As shown in fig. 3, currently, the conduction of the internal signal circuit of the electrical box uses an internal signal circuit conduction connector 101 with an internal signal circuit terminal 200. The inner signal circuit terminal 200 of the inner signal circuit conductive connector 101 is formed in a U-shaped sheet shape, and both side portions are formed with barbs. When inserted into the connector 101, the internal signal return terminal 200 is inserted into the connector 101 by being pressed in from the front end of the connector, and the signal terminal is fixed by barbs on both side portions of the internal signal return terminal 200.
As shown in fig. 4, the connection of the electrical box to the external signal circuit uses the external signal circuit continuity connector 102 with the external signal circuit terminal 300. The external signal circuit terminals 300 of the external signal circuit conductive connector 102 are generally used in pairs, and each of the external signal circuit terminals 300 is integrally formed in an elongated rod shape including a terminal-bayonet fixing face and a pin portion extending forward from one end of the terminal-bayonet fixing face, and a wire-harness crimping portion extending rearward from the other end of the terminal-bayonet fixing face. After being respectively crimped with the wire harnesses, the external signal circuit terminal 300 is inserted into the connector 102 from the rear end thereof and fixed in the connector housing by the bayonet structure of the connector housing. The connector 102 is conducted with an external signal by a wire harness crimped to the external signal circuit terminal 300.
Disclosure of Invention
Technical problem
However, the above background art has the following problems.
As is apparent from fig. 3 and 4, the internal signal circuit terminal and the external signal circuit terminal are different in configuration, and the connector with the internal signal circuit and the connector with the external signal circuit are also different in internal configuration. There are multiple sets of terminals and their connectors that perform different functions for one electrical box, and therefore the cost of the signal terminals and their connector housing molds is high. In addition, the corresponding connector mounting portions are provided corresponding to different connectors, which results in that the positions of the internal and external signal circuit connectors cannot be interchanged, and the versatility is poor, resulting in a limitation in the layout of the connectors on the electrical box.
If only the internal signal circuit terminal and its dedicated connector are used on the electrical box, the electrical box can only conduct the internal signal circuit, and when the electrical box is to be connected with the external signal circuit, it is necessary to additionally use a signal output connector and provide a corresponding connector mounting portion on the electrical box, similar to the case shown in fig. 1 and 2, resulting in a complex structure and high cost of the electrical box.
If only the external signal circuit terminal and its dedicated connector are used on the electrical box, when it is necessary to achieve conduction of the internal signal circuit of the electrical box, it is necessary to make the wire harnesses crimped to a pair of external signal circuit terminals conduct each other (circuit turning). But the cost of the two signal terminals and the cost of the crimping of the signal terminals to the wire harness are high.
In addition, the internal signal circuit terminal with barbs can scratch the connector housing during the process of pressing the connector, and the barbs can also reduce the service life of the die during the production and stamping processes of the die.

In the electrical box according to the second aspect of the present invention, the internal signal circuit terminal is formed to include: a pair of body portions arranged to be opposed to each other; a connecting portion through which respective one ends of the pair of body portions are connected to each other; and a pair of terminal pin portions respectively extending forward from the other ends of the pair of body portions, the pair of terminal pin portions conforming to a connector fitting direction when fitted in the connector housing to be electrically connected with a counterpart terminal, wherein the internal signal circuit terminal is U-shaped as a whole, wherein a locking structure for locking to the connector housing is formed on the body portions.
The locking structure of the internal signal circuit terminal is formed with a terminal buckle formed by bending a cut part of each of a pair of main bodies toward the opposite main body, wherein a terminal buckle insertion surface inclined is formed at the tip of the terminal buckle.
In the electrical box according to the second aspect of the present invention, the external signal return terminal is formed in a rod shape, including: a terminal snap connector mounting portion for fixing with the connector housing; a pair of terminal pin portions extending forward from one end of the terminal snap connector mounting portion, the pair of terminal pin portions being aligned with a connector fitting direction when fitted in the connector housing to be electrically connected with a counterpart terminal; a crimping part to which the signal line is crimped.
In the electrical box according to the second aspect of the invention, the connector housing is configured to include: a main circuit terminal accommodating portion; a signal terminal insertion portion for inserting a signal terminal; a signal terminal insertion port that opens toward one end of the connector housing; a signal terminal engaging member that is formed integrally with the signal terminal insertion portion of the housing and that is formed in an inner cavity of the signal terminal insertion portion to partition the inner cavity of the signal terminal insertion portion into two signal terminal accommodating chambers, wherein the signal terminal engaging member is formed with two lance-shaped fixing clips at one end away from the signal terminal insertion port, and the other end of the signal terminal engaging member extends toward the signal terminal insertion port with a space between an end surface of the signal terminal insertion portion, and wherein the two signal terminal accommodating chambers communicate at the signal terminal insertion port side through the space between the signal terminal engaging member and the end surface of the signal terminal insertion portion. An inner signal circuit through connector is obtained when an inner signal circuit terminal is inserted inside the connector housing, and wherein an outer signal circuit through connector is obtained when an outer signal circuit terminal is inserted inside the connector housing.

In addition, because the connector shell of the internal signal loop conducting connector is completely the same as that of the external signal loop conducting connector, the universality of the connector installation part on the connector and the flexibility of the layout of the connector are further realized, and meanwhile, because the same connector shell is used, the internal signal loop conducting connector or the external signal loop conducting connector can be obtained by inserting the internal signal loop terminal or the external signal loop terminal, the cost of the connector is reduced at the same time, and the universality of the overall cost of the electric box is reduced.
In addition, because the inner signal loop terminal is not provided with the barbs, the damage of the inner signal loop terminal to the connector is reduced, and the service life of the connector is prolonged.

[ case of general Signal Circuit continuity connector ]
A housing of a general signal circuit conductive connector that can be commonly used for an internal signal circuit conductive connector and an external signal circuit conductive connector according to the present invention will be described in detail below with reference to fig. 7 to 9.
Fig. 7 is a perspective view of a housing of the universal signal circuit conductive connector 1 according to the present invention, fig. 8 is a perspective sectional view of the housing of the universal signal circuit conductive connector 1 shown in fig. 1, and fig. 9 is a sectional view of a structure of the housing of the universal signal circuit conductive connector 1 according to the present invention.
As shown in fig. 7 to 9, the housing of the signal loop conductive connector 1 mainly includes: the main loop terminal accommodating part is used for accommodating the terminals of the main loop so as to realize the conduction of the main loop; a signal terminal insertion portion 10 for inserting a signal terminal; a signal terminal insertion port 11, the signal terminal insertion port 11 being formed inside one end (rear end) of the signal terminal insertion portion 10 and being open toward the one end of the signal terminal insertion portion 10; and a signal terminal engaging member 12, the signal terminal engaging member 12 being formed integrally with the signal terminal insertion portion 10 of the housing and being formed in the inner cavity of the signal terminal insertion portion 10 to divide the inner cavity of the signal terminal insertion portion 10 into two signal terminal accommodating chambers 14a and 14b, the two signal terminal accommodating chambers 14a and 14b for accommodating and fixing the signal terminals.
The signal terminal engaging member 12 is formed at an end remote from the signal terminal insertion port 11 with a pair of lance-like fixing catches 13 projecting into the two signal terminal accommodating chambers 14a and 14b, respectively, for engaging and fixing the signal terminals to be inserted. A space 19 is provided between the other end of the signal terminal engaging member 12 close to the signal terminal insertion port 11 and the end surface of the signal terminal insertion portion 10 on the signal terminal insertion port 11 side, and the two signal terminal accommodating chambers 14a and 14b communicate on the signal terminal insertion port 11 side through the space 19 to accommodate a part of the terminals.
[ inner signal loop conductive connector ]
First, the internal signal circuit terminal to be inserted into the internal signal circuit conductive connector is described.
Fig. 10 shows an internal signal return terminal 2 according to the present invention, which has two flat body portions 21 opposed in parallel and is formed in a U shape as a whole by a connecting portion 22 connecting the two body portions 21 on one side. On the other, unconnected sides of the two body portions 21, there are formed forwardly extending terminal pin portions 23, respectively, to facilitate insertion of the terminals into the connector housing and electrical connection with mating terminals.
The main body 21 of the internal signal circuit terminal 2 is provided with a terminal catch 24 formed by cutting a part of each of the pair of main bodies 21 and bending the cut part toward the other main body 21 facing the main body 21. The terminal catch insertion surface 25 is formed by forming the mutually facing sides of the pair of terminal catches 24 as inclined surfaces for guiding the insertion of the internal signal circuit terminal 2 in the connector housing. In addition, the side surfaces of the terminal hooks 24 form terminal hook fixing surfaces 26, which serve to fix the terminal hooks in the connector housing after insertion.
As shown in fig. 14, when the internal signal circuit terminal 2 according to the present invention is inserted into the general signal circuit conductive connector 1, the general signal circuit conductive connector 1 becomes an internal signal circuit conductive connector.
When the general-purpose signal circuit conductive connector 1 is an internal signal circuit conductive connector, the terminal catch insertion surface 25 of the terminal catch 24 of the internal signal circuit terminal 2 passes over the fixing catch 13 of the signal terminal engaging member 12 of the housing of the signal circuit conductive connector 1 in the process of inserting the internal signal circuit terminal 2 into the signal circuit conductive connector 1. When the terminal catch insertion surface 25 completely passes over the fixing catch 13, the terminal catch fixing surface 26 of the internal signal circuit terminal 2 is engaged with the fixing catch 13 of the signal terminal engaging member 12 of the housing of the signal circuit on connector, thereby preventing the internal signal circuit terminal 2 from moving away from the signal terminal insertion portion 10 of the housing. At this time, the connecting portion 22 of the internal signal circuit terminal 2 abuts on one end of the signal terminal engaging member 12 located at the signal terminal insertion port 11, that is, the connecting portion 22 is accommodated in the space 19, and the pair of body portions 21 of the internal signal circuit terminal 2 are respectively accommodated in the two signal terminal accommodating chambers 14a and 14b of the signal terminal insertion portion 10 of the housing of the signal circuit conduction connector 1.
After the internal signal circuit terminal 2 is inserted into the universal signal circuit conductive connector 1, the signal terminal insertion opening 11 in the housing is closed by a waterproof pad 17a with a signal wire hole as shown in fig. 12a, so that the connection portion 22 of the internal signal circuit terminal 2 is fixed in the space 19 and plays a waterproof role. The housing is then closed using a pin backed cover 15a as shown in fig. 13 a.
As shown in fig. 12a, the signal hole waterproof pad 17a is formed with a pair of signal line lead-out holes 18, and as shown in fig. 13a, the pin rear cover 15a is formed with a pair of pin structures 16a at positions corresponding to the signal line lead-out holes 18 of the signal hole waterproof pad 17 a. When the waterproof pad 17a with the signal hole and the rear cover 15a with the pin are respectively fitted to the universal signal circuit conduction connector 1, as shown in fig. 14, the pin structure 16a of the rear cover 15a with the pin is inserted into the signal line lead-out hole 18 of the waterproof pad 17a with the signal hole, thereby further performing a waterproof function.
Alternatively, a waterproof pad and a rear cover as shown in fig. 12b may also be used. Specifically, the signal-hole-free waterproof pad 17b is not formed with a signal-line lead-out hole, but is instead formed as a closed waterproof surface. As shown in fig. 13a, the pinless rear cover 15b is not formed with a pin structure, but is formed with a pair of signal line outlet ports 16b at positions corresponding to the signal line lead-out holes 18 of the signal hole waterproof pad 17 a. When the signal hole-less waterproof pad 17b and the pin-less rear cover 15b are fitted to the universal signal circuit conductive connector 1 in this order, only the waterproof surface of the signal hole-less waterproof pad 17b plays a waterproof role, and the connecting portion 22 of the internal signal circuit terminal 2 is fixed in the space 19. The pin-less rear cover 15b merely functions to close the universal signal circuit continuity connector 1.
[ external signal circuit conductive connector ]
First, the external signal circuit terminal to be inserted into the external signal circuit conductive connector is described.
As shown in fig. 11, the external signal circuit terminal 3 is formed in a rod shape as a whole, and mainly includes: a main body 31 having a snap connector mounting part fixed to the housing of the signal circuit continuity connector; a terminal pin portion 32 facilitating insertion of the terminal into the connector housing and electrical connection with a mating terminal; and a crimping portion 33 for crimping with the wire. The external signal return terminals are generally used in pairs.
As shown in fig. 15, when the external signal circuit terminal 3 is inserted into the signal circuit conductive connector 1, an external signal circuit conductive connector is obtained. At this time, the pair of external signal circuit terminals 3 are inserted into the signal terminal insertion portions 10 of the housing of the signal circuit conductive connector 1 and engaged with the fixing catches 13 of the signal terminal engaging members 12.
After the external signal circuit terminal 3 is inserted into the universal signal circuit conductive connector 1, the signal terminal insertion port 11 in the housing is closed by the signal wire hole waterproof pad 17a as shown in fig. 12a, and the signal wires connected to the external signal circuit terminal 3 are led out through the signal wire lead-out holes 18 of the signal wire hole waterproof pad 17a, respectively. Then, the housing is closed using the pin-less rear cover 15b as shown in fig. 13b, while the signal lines connected to the external signal circuit terminals 3 are led out through the pair of signal line outlets 16b, respectively. Thus, by using the waterproof pad 17a with the signal line hole and the rear cover 15b without a pin, both the waterproof function and the derivation of the signal line are realized.

In particular, since the fixing positions and the sizes of the internal signal circuit conducting connector and the external signal circuit conducting connector are completely the same, the positions of A, B, C, D four connectors can be arbitrarily interchanged, thereby satisfying various requirements for signal output of the electrical box, and since the external signal circuit conducting connector B is provided with a signal output line itself, that is, a signal line crimped to the external signal circuit terminal 3, it is not necessary to add a different connector mounting portion and a signal output connector E to conduct with the external circuit as in the electrical box of the background art shown in fig. 1 and 2.
The embodiments of the electrical box according to the present invention and its internal signal circuit terminal and general signal circuit continuity connector have been described above, but the present invention is not limited to the above-described embodiments, and various changes can be made to the present invention without changing the gist of the present invention.
Industrial applicability
