Detailed Description
For a better illustration of the objects, technical solutions and advantages of the present utility model, the following detailed description of the present utility model will be given with reference to the accompanying drawings and examples.

The pair of conductive terminals 12 are disposed axially in parallel in the insertion hole or the insertion post of the insulating housing 11 for conducting connection when the connector of the present embodiment is inserted into another connector.
The front end of the insulating housing 11 may be configured with a socket or a socket post, and a first signal terminal 40 is further disposed therein. The first signal terminal 40 is composed of a terminal block, a terminal contact, and an elastic member. The terminal contact is arranged on the terminal seat in a sliding way along the axial direction of the sliding groove of the terminal seat, and the terminal contact can have forward elasticity on the terminal contact when the terminal contact slides backwards through the elastic piece.
If the insulating housing 11 of the connector is configured as a jack, the first signal terminal 40 is mounted at the bottom of the jack. When not under pressure, the terminal contacts protrude outward of the receiving holes. The terminal contacts may slide back to the bottom of the socket when subjected to pressure. After the pressure is released, the terminal contact protrudes out of the jack again under the action of the elastic force. Thus, when the connector is plugged into another connector provided with a plug post, the terminal contact will be pushed into the terminal base by the plug post connector, and the plug post connector will be able to complete mating with the connector of the present embodiment. Meanwhile, when the connector of the embodiment is in butt joint with another connector with the same built-in signal, the terminal contact keeps the conductive contact of the connector with the built-in signal under the action of the elastic piece, so that signal transmission is realized.
Similarly, if the insulative housing 11 of the connector is configured as a post, the first signal terminals 40 may be mounted on top of the post. When not under pressure, the terminal contacts project outwardly toward the top of the socket post. The terminal contact may slide back into the top of the socket post when subjected to pressure. After the pressure is released, the terminal contact protrudes outwards towards the top of the plug post again under the action of the elastic force. Therefore, when the insulating housing 11 of the connector is configured as a plug, the connector can be not only adapted to another connector matched with a plug hole in the old version and realize a conductive basic function, but also adapted to another connector of a built-in signal in the new version and realize a conductive function and a signal transmission function.
Therefore, the first signal terminal 40 which can elastically reset and stretch and slide is arranged in the jack or the jack post of the insulating shell 11, so that the plug connector can be not only suitable for plugging an old type connector, but also can perform signal transmission in the process of plugging a new type connector, and the function of enriching products on the basis of meeting compatibility is realized.
In particular, in the present embodiment, the first signal terminal 40 is disposed between the pair of conductive terminals 12, and the axis of the first signal terminal 40 is the same as the distance between the axes of the two conductive terminals 12, respectively. Generally, the pair of conductive terminals 12 is used for transmitting power in the positive and negative circuits, and the first signal terminal 40 is disposed in the middle of the two conductive terminals 12, so that the space inside the jack or jack post can be fully utilized.
In particular, the first signal terminal 40 is configured as one or two. In general, a signal loop with positive and negative poles is required for transmitting signals, and two first signal terminals 40 are provided to form a complete signal transmission. In some other embodiments, the connector may be configured with one conductive terminal 12 as the signal positive line and the negative conductive terminal as the signal negative line.
In particular, in this embodiment, the front end of the insulating housing 11 is provided with a jack, and the conductive terminal 12) is configured as a conductive male terminal, and the first signal terminal 40 extends outward from the bottom of the jack. Since the first signal terminals 40 are disposed in the jack, the first signal terminals 40 can be protected inside the insulating housing 11, thereby improving the service life of the jack connector. In other embodiments, where the front end of the insulating housing 11 is configured with a socket post, the conductive terminal 12 is configured as a conductive female terminal, and the first signal terminal 40 may also be provided at the front end of the socket post and extend forward.
As shown in fig. 2 to 6, a connector assembly of a built-in channel according to an embodiment of the present utility model. The connector assembly includes a first connector 20 and a second connector 30.

Wherein the second connector 30 is configured as a female terminal male plug structure that mates with the first connector 20, and includes an insulative male housing 31 and a pair of conductive female terminals 33. The front end of the insulating male housing 31 is provided with a socket post 32, and a pair of conductive female terminals 33 axially parallel to each other are provided in the socket post 32. In detail, the first connector 20 and the second connector 30 are mated with each other so that the socket posts 32 of the insulative male housing 31 can be inserted into the socket holes 22 of the insulative female housing 21 while each of the conductive male terminals 23 can be inserted into the inside of each of the conductive female terminals 33 in a one-to-one correspondence.
In this embodiment, the connector assembly is applied to power transmission in a system composed of a battery, a charger and a load. The pair of conductive male terminals 23 of the first connector 20 and the pair of conductive female terminals 33 of the second connector 30 may be used to conduct positive and negative power of the system.
Such connector assembly, the insulative female housing 21 and the insulative male housing 31 serve as insulation and protection for the portion to be held during insertion. Generally, the outer shapes of the insulating female housing 21 and the insulating male housing 31 are approximately rectangular parallelepiped shapes. The jack 22 is provided at the front end of the rectangular parallelepiped long side of the insulating female housing 21, the conductive male terminals 23 extend in the rectangular parallelepiped long side direction, and a pair of conductive male terminals 23 are arranged in the rectangular parallelepiped wide side direction. Further, the sectional shapes of the socket 22 and the socket post 32 are configured to be approximately rectangular. The socket post 32 has a smaller profile than the insulating male housing 31 to form a limited step. On the basis of being capable of being in plug-in fit and insulating surrounding the conductive female terminal 33, the plug-in post 32 can be provided with a groove extending along the long side direction of the cuboid so as to achieve the purpose of saving materials. The contour of the socket 22 matches the contour of the socket post 32. In some aspects, the socket 22 may be sized slightly smaller than the socket post 32 to allow for more secure connection. A material-reducing groove may be provided on the inner wall of the insertion hole 22. The conductive male terminal 23 is substantially cylindrical, and the conductive female terminal 33 is also substantially cylindrical and has a cylindrical hole formed therein, so that the conductive male terminal 23 is inserted into the conductive female terminal 33. To ensure the stability of the conduction of the terminal, the conductive male terminal 23 is provided with a cross groove, and the outer diameter is slightly larger than that of the conductive female terminal 33, so that each part of the conductive male terminal 23 divided by the cross groove will elastically deform toward the center during plugging, and a contact pressure is applied to the inner wall of the hole of the conductive female terminal 33.
For the purpose of the present utility model, in the present embodiment, the first connector 20 is further provided with a first signal terminal 40, and the first signal terminal 40 is disposed in the insertion hole 22 of the insulating female housing 21 so as to extend in the insertion direction. Meanwhile, the second connector 30 is further provided with a second signal terminal 50, and the second signal terminal 50 is disposed in the socket post 32 of the insulating male housing 31 so as to extend in the socket direction.
The first signal terminal 40 includes a terminal block 41, a terminal contact 42, and an elastic member 43. The terminal block 41 is fixed to the insulating female housing 21, a slide groove extending in the plugging direction is provided in the terminal block 41, the elastic member 43 is fitted in the slide groove of the terminal block 41, and the terminal contact 42 is provided on the terminal block 41 slidably in the axial direction of the slide groove. One elastic end of the elastic member 43 abuts against the bottom of the sliding slot of the terminal block 41, and the other elastic end of the elastic member 43 abuts against the rear end of the terminal contact 42. Thus, when the front end of the terminal contact 42 is pressed, the terminal contact 42 will retract back into the slide groove of the terminal block 41, while the elastic member 43 applies a forward elastic force to the terminal contact 42. When the pressure applied to the terminal contact 42 is released, the terminal contact 42 projects forward along the inside of the slide groove of the terminal block 41 under the action of elastic force.
The second signal terminal 50 is disposed at a position corresponding to the first signal terminal 40 such that the front end of the second signal terminal 50 abuts against the first signal terminal 40 when the first connector 2020) and the second connector 30 are connected by plugging. Meanwhile, the front end position of the second signal terminal 50 does not exceed the front end of the socket post 32 of the second connector 30, so that the second signal terminal 50 is exposed from the front end of the socket post 32, and the obstruction caused by the second signal terminal 50 when the second connector 30 is separately plugged is avoided.
Referring to fig. 3 and 4, when the first connector 20 is plugged with the second connector 30, the plug-in hole 22 of the insulating female housing 21 is plugged with the plug-in post 32 of the insulating male plastic housing, the pair of conductive male terminals 23 are plugged into the pair of conductive female terminals 33 in a one-to-one correspondence manner, meanwhile, due to the correspondence of positions, the terminal contact 42 of the first signal terminal 40 is pushed by the second signal terminal 50 to retract into the sliding groove of the terminal seat 41, and the first signal terminal 40 and the second signal terminal 50 keep conductive contact under the action of the elastic piece 43, so that not only can electric power transmission be realized through the conductive male terminal 23 and the conductive female terminal 33, but also signal transmission can be realized through the first signal terminal 40 and the second signal terminal 50, and abundant functions such as battery parameter identification, battery electric control and the like can be realized by signal expansion.
For example, when the first connector 20 is applied to a charging device or a load and the second connector 30 is applied to a battery, not only power transmission but also signal transmission can be achieved when the battery provided with the second connector 30 is connected with the charging device or the load provided with the first connector 20. Meanwhile, the first signal terminal 40 is provided in the jack 22, and the second signal terminal 50 is provided in the jack post 32, and neither the insulating female housing 21 nor the insulating male housing 31 need to be changed in external profile dimensions, so that the design dimensions of the charging device or the mounting connector on the load need not be changed.
Referring to fig. 5, when the first connector 20 is plugged with the old male-female connector 601, the plug hole 22 of the first connector 20 is plugged into the male-female structure of the old male-female connector 601, the male-male structure of the old male-female connector 601 is abutted against the terminal contact 42 of the first signal terminal 40, and pushes the terminal contact 42 to retract into the sliding groove of the terminal block 41, so that the first connector 20 and the old male-female connector 601 can be successfully docked. For example, if the first connector 20 is applied to a charging device or load, then the old battery may be plugged into the charging device or load equipped with the first connector 20.
Referring to fig. 6, when the second connector 30 is plugged with the old female-male connector 602, the plug post 32 of the second connector 30 is inserted into the female-male connector, and since the front end of the second signal terminal 50 is located inside the front end of the plug post 32 of the second connector 30, the front end of the plug post 32 of the second connector 30 is not contacted with the bottom of the female-male connector 602 when the front end of the second signal terminal 50 is plugged into the old female-male connector 602, so that the second connector 30 and the old female-male connector 602 can be successfully docked. For example, the second connector 30 is applied to a battery, which can be plugged into a charging device of the old version for charging, while the battery can be plugged into a load of the old version for supplying power.
Therefore, when the first connector 20 and the second connector 30 are mated and plugged, the signal transmission function can be realized on the basis of the conductive function, so that the abundant functions such as battery parameter identification and battery electric control are realized by signal expansion, and the user experience is improved. When the first connector 20 is individually connected to the old male-female connector 601, the first connector 20 can smoothly complete the connection, and the first signal terminals 40 do not constitute an obstacle. When the second connector 30 is separately connected to the old female-male connector 602, the second connector 30 can smoothly complete the connection, and the second signal terminals 50 do not constitute an obstacle.

The distance between the axis of any one of the first signal terminals 40 and the axis of the positive conductive male terminal 23 is equal to the distance between the axis of the first signal terminal 40 and the axis of the negative conductive male terminal 23. The two first signal terminals 40 can form a signal transmission loop, meanwhile, the arrangement positions of the first signal terminals 40 fully utilize the space inside the jack 22, meanwhile, the distance between the first signal terminals 40 is reasonable, and the distance between the first signal terminals 40 and the conductive male terminal 23 is reasonable, so that the situations of short circuit, electric shock error and the like are avoided. Similarly, the arrangement of the second signal terminals 50 has similar characteristics.
With respect to the connector assembly, as shown in fig. 3 and 4, in the first connector 20, the rear end of the conductive male terminal 23 is provided with a right angle pin extending rearward beyond the insulative female housing 21, thereby achieving board patch soldering of the charging device or load.
