Description

Conductive structure and electric connector

Technical Field

The utility model belongs to the technical field of electric connectors, and particularly relates to a conductive structure and an electric connector.

Background

In the electrical connector, a secondary MOLDING structure is used for connection, and MOLDING means MOLDING and shaping. When the secondary MOLDING structure is manufactured, a groove is formed after two primary MOLDING parts are overlapped, and then secondary MOLDING conductive materials are carried out in the groove, wherein the conductive materials are formed by taking the two primary MOLDING parts which are overlapped together as a mould, so that the secondary MOLDING structure is obtained, and the secondary MOLDING structure connects appointed terminals in the two primary MOLDING parts, so that the secondary MOLDING parts are obtained.

However, in the above manner, when the secondary moving is performed, since the two primary moving members are overlapped, the conductive material can be injected from the notch at the left and right ends, the inside of the groove is deeper, and a larger pressure is required for filling, and since the strength of the overlapped position of the two primary moving members is lower, the conductive material is liable to break the primary moving member, and the conductive material flows out to be in contact with other terminals, thereby causing short circuit. Therefore, the structure of stacking two primary MOLDING parts and then secondary MOLDING conductive materials has higher requirements on an injection MOLDING machine, and the primary MOLDING parts are easy to crack to cause short circuit when the injection MOLDING machine is not well regulated.

Therefore, a new technology is needed to solve the problems of high requirement on injection MOLDING machine adjustment and easy short circuit in the secondary MOLDING in the prior art.

According to the utility model, only one primary MOLDING piece 211 is adopted in the secondary MOLDING process, so that the weak point of the two primary MOLDING pieces 211 when overlapped is eliminated, and the phenomenon that the primary MOLDING piece 211 is broken and flows out to be contacted with a gas terminal when the conductive material is injected is avoided, thereby avoiding short circuit.

Example 1

Referring to fig. 1 to 10, the present embodiment provides a conductive structure 100, which includes a housing 1 and at least one connection assembly 2, wherein each connection assembly 2 includes two secondary MOLDINGs 21.

The number of the connection members 2 may be one or plural, for example, two, three, four or even more. Referring to fig. 3, a connection assembly 2 has two secondary moving parts 21, and the two secondary moving parts 21 may be disposed opposite to each other to form a fit for inserting corresponding terminal heads.

Referring to fig. 3, each secondary moving element 21 includes a primary moving element 211 and a secondary moving structure 212, the primary moving element 211 includes an insulating main body 2111 and a terminal group 2112, the insulating main body 2111 is provided with a conductive trough 21111, and a first positioning structure 21112 is provided outside the insulating main body 2111; the secondary MOLDING structure 212 is injection molded from a conductive material within the conductive trough 21111.

That is, in the primary shaping, the terminal set 2112 and the insulating main body 2111 are molded and fixed together to obtain a primary shaping member 211, then a secondary shaping is performed by using the primary shaping member 211 and the conductive material, the conductive material is injection molded in the conductive trough 21111 of the insulating main body 2111 to form a secondary shaping structure 212, and the combination of the primary shaping member 211 and the secondary shaping structure 212 is the secondary shaping member 21.

Note that, depending on the number of pins in the terminal group 2112, the 6P terminal group 2112a, the 14P terminal group 2112b, and the 28P terminal group 2112c may be different, respectively. Two terminal sets 2112 in the same connection assembly 2 contain the same number of pins, e.g., 6P, 14P, 28P, etc. Of course, if there are a plurality of connection assemblies 2, the number of pins in different connection assemblies 2 may be different, for example, one connection assembly 2 has a terminal group 2112 of 6P, another connection assembly 2 has a terminal group 2112 of 14P, and another connection assembly 2 has a terminal group 2112 of 28P.

Referring to fig. 3, in the present embodiment, four connection assemblies 2 are shared, wherein the terminal group 2112 in one connection assembly 2 is 6P, the terminal group 2112 in one connection assembly 2 is 14P, and the terminal group 2112 in two connection assemblies 2 is 28P.

In this embodiment, only one primary moving member 211 is adopted during the secondary moving, so that the weak structure of the two primary moving members 211 during the combination is reduced, and the short circuit caused by the conductive material breaking and flowing out during the secondary moving can be avoided. Because the strength of the single primary moling piece 211 is strong, the pressure in the secondary moling can be adapted, and thus the requirement on the injection MOLDING machine is low.

Referring to fig. 2, the housing 1 is provided with a mounting groove 11 in which two secondary MOLDINGs 21 are mounted and two terminal groups 2112 are opposite, and a second positioning structure 12 matching with the first positioning structure 21112 is disposed in the mounting groove 11. I.e. when installed in the housing 1, two secondary moving elements 21 are required to be arranged opposite to each other to form one connecting assembly 2. Due to the arrangement of the first positioning structure 21112 and the second positioning structure 12, the secondary moving element 21 can form positioning without offset when being inserted into the mounting groove 11, and the two secondary moving elements 21 can form opposite fit.

In the conventional scheme, the two primary moving pieces 211 are stacked and then subjected to secondary moving, so that a whole is formed after the two primary moving pieces 211 are completed, and then the secondary moving piece 21 (the secondary moving structure 212 comprising two insulating bodies, two terminal groups 2112 and conductive material) is inserted into the housing 1, so that an additional positioning structure is not required to fixedly match the terminal groups 2112 in the two primary moving pieces 211.

However, in this embodiment, since only one primary moving member 211 is used for the secondary moving, only one terminal group 2112 is contained in the obtained secondary moving member 21, and the two secondary moving members 21 are not paired, and therefore, when the housing 1 is connected, the two secondary moving members 21 need to be disposed and fixed to each other so as to form a fit. Thus, the positioning structures (i.e., the first positioning structure 21112 and the second positioning structure 12) are provided in this embodiment. It will be appreciated that the number of mounting slots 11 and the number of connection assemblies 2 are in a one-to-one correspondence, with one connection assembly 2 (i.e. two secondary moving members 21) being mounted in each mounting slot 11.

Wherein the first positioning structures 21112 are located at both ends of the insulating body in the length direction. The first positioning structure 21112 is a positioning slot and the second positioning structure 12 is a positioning block that mates with the positioning slot. Alternatively, the first positioning structure 21112 is a positioning block and the second positioning structure 12 is a positioning slot that mates with the positioning block. Alternatively, the first positioning structure 21112 is a tab and the second positioning structure 12 is a notch that mates with the tab. Alternatively, the first positioning structure 21112 is a notch and the second positioning structure 12 is a tab that mates with the notch. That is, the first positioning structure 21112 and the second positioning structure 12 are in concave-convex fit, one is concave, and the other is convex, so that the positioning is realized.

Based on the above structure, only one primary MOLDING piece 211 is adopted in the process of carrying out the secondary MOLDING, and two primary MOLDING pieces 211 are not required to be overlapped, so that weak links are reduced, the phenomenon that the conductive material breaks through the primary MOLDING piece 211 in the process of carrying out the secondary MOLDING can be avoided, and the short circuit caused by the fact that the conductive material flows out to be combined with other terminals is avoided.

Example two

Referring to fig. 1 to 10, the present embodiment provides a conductive structure 100, which further has the following design based on the first embodiment:

referring to fig. 2 to 6, the first positioning structure 21112 is a notch formed at two ends of the insulating main body 2111, and the second positioning structure 12 is a protruding block protruding from the inner wall of the mounting groove 11 and capable of being engaged with the notch in a matching manner.

As shown in fig. 5, notches are formed at the left and right ends of the insulating body 2111, the shape of which is adapted to the shape of the protrusions provided at the left and right ends of the mounting groove 11.

When the two are engaged, the position of the insulating body 2111 in the mounting groove 11 can be determined, and no offset can occur. The same principle applies to the opposite side, so that when two secondary moving parts 21 in the same connecting assembly 2 are mounted in the mounting groove 11, the two secondary moving parts 21 can be opposite, and the terminal groups 2112 thereof can be matched relatively.

The notches at the same end of the two secondary MOLDINGs 21 may be located away from each other, and correspondingly, the two bumps are also located away from each other. The notches at the same end of the two secondary moving members 21 may be disposed close to each other, and correspondingly, the two bumps may be disposed close to each other.

In this embodiment, as shown in fig. 5, the protruding blocks of the two secondary moving parts 21 are oppositely disposed and connected to form a groove, and the two protruding blocks are combined to form a positioning strip.

That is, in this embodiment, two notches are disposed relatively close together and on the edge, so that the notches can be joined together in the mounting groove 11 to form a recess. Correspondingly, two lugs are also arranged close together and connected together to form a locating strip. Under the structure, two lugs are changed into one large lug, so that the structure of the shell 1 is simplified, and the mould in the shell 1 is simplified.

Example III

Referring to fig. 1 to 10, the present embodiment provides a conductive structure 100, which further has the following design based on the first embodiment:

referring to fig. 5 to 7, a notch of the conductive groove 21111 is formed at a side of the insulating body 2111 facing the other insulating body 2111.

That is, in the same connection assembly 2, the notches of the conductive grooves 21111 on the two insulating bodies 2111 are both inward facing when installed in the installation groove 11, and the two insulating bodies 2111 are opposed.

After setting up the notch in this position, the notch is in on the plane that the long limit is located, and the notch has longer length, and the degree of depth is then shallower relatively, because the length of notch is enough, when moulding plastics conductive material, can set up a plurality of mouthfuls of moulding plastics on the notch, carries out the injection molding simultaneously, can accelerate the speed of moulding plastics, is used for the slot degree of depth shallower simultaneously, is full of easily, avoids the hourglass.

If notches are formed at both left and right ends of the insulating body 2111 and injection molding is performed, as in the conventional technique, the depth of the notches is deep, the filling speed is low, and void is likely to occur.

The other surface of the insulating body 2111 needs to be in contact with the inner wall of the mounting groove 11, so that a space is reserved, and the notch of the conductive groove 21111 is not suitable.

Further, referring to fig. 7, in this embodiment, the secondary MOLDING structure 212 fills the conductive trough 21111 and is flush with the side of the insulating body 2111 at the notch of the conductive trough 21111. The conductive material needs to be filled up during the secondary MOLDING to avoid the cavity and influence on the conductive performance. Whereas the secondary moving structure 212 is insulated flush with the side of the insulating body 2111, i.e. has no protruding structure, to avoid obstructing the relative mating of the two secondary moving members 21.

Example IV

Referring to fig. 1 to 10, the present embodiment provides a conductive structure 100, which further has the following design based on the first embodiment:

referring to fig. 6 and 10, the terminal group 2112 includes a plurality of wide P terminals 21121 and narrow P terminals 21122 regularly arranged in the insulating body 2111, and the conductive groove 21111 is provided with a plurality of through holes 21114 communicating with each of the wide P terminals 21121.

The wide P terminal 21121 is a ground terminal for grounding. The narrow P terminal 21122 is a signal terminal for connecting a signal line for signal transmission.

The wide P terminals 21121 and the narrow P terminals 21122 may be arranged at intervals or in a specific regular arrangement.

For example, in the 28P terminal group 2112c, as shown in fig. 7, the first left side is a wide P terminal 21121, two narrow P terminals 21122 are connected, and the other wide P terminal 21121 is connected to two narrow P terminals 21122, and the cycle is continued until 28P is full, at which point the wide P terminal 21121 ends. I.e., one wide P terminal 21121 is provided after every two narrow P terminals 21122.

For example, in the 14P terminal group 2112b, as shown in fig. 9, the first narrow P terminal 21122 on the left side and the second wide P terminal 21121 are connected to two narrow P terminals 21122 and the other wide P terminal 21121 is connected to two narrow P terminals 21122, and the cycle is continued until 14P is full, at which point the wide P terminal 21121 ends.

The conductive trough 21111 is provided with a plurality of via holes 21114 and each wide P terminal 21121, under this structure, each wide P terminal 21121 can be connected by conduction through a secondary MOLDING structure 212 formed by the corresponding via hole 21114 and conductive material, and the secondary MOLDING structure 212 is connected to a ground line, so as to connect the wide P terminal 21121 to a ground line, thereby realizing grounding.

In one embodiment, the conductive material flows through each of the via holes 21114 before being formed to be connected to each of the wide P terminals 21121 and to be conducted to each of the wide P terminals 21121 after being formed, referring to fig. 6. That is, in the case of the secondary MOLDING, the injected conductive material is flowing, not yet molded, and can flow from the notch to fill each space in the groove, and when it flows to the via hole 21114, it will also fill the via hole 21114, and the via hole 21114 is connected to the wide P terminal 21121 in communication, so that the conductive material will also be connected to and conducted with the wide P terminal 21121, and after the conductive material is molded, the secondary MOLDING structure 212 is formed, that is, the secondary MOLDING structure 212 is connected to and conducted with the wide P terminal 21121.

Example five

Referring to fig. 1 to 10, the present embodiment provides a conductive structure 100, which further has the following design based on the first embodiment:

That is, after the secondary moving member 21 is inserted into the mounting groove 11, although the two secondary moving members 21 can be opposite to each other by the cooperation of the first positioning structure 21112 and the second positioning structure 12, the secondary moving member 21 may be separated from the mounting groove 11 due to the fact that the secondary moving member 21 is merely inserted into the mounting groove 11 and is forced to be inserted into or pulled out from other structures when in use. To avoid this problem, the above-described card slot 13 and buckle 21113 are provided in the present embodiment.

When the secondary moving member 21 is inserted into the mounting groove 11, the buckle 21113 on the outer side of the insulating body 2111 thereof can be inserted into the clamping groove 13 on the inner wall of the mounting groove 11, the buckle 21113 is protruded, and is engaged with the clamping groove 13, and resistance can be formed in the notch direction, so that the secondary moving member 21 is prevented from being separated from the notch of the mounting groove 11.

Further, referring to fig. 5, the lower end of the buckle 21113 is an inclined plane, that is, the buckle 21113 is wedge-shaped, so that the buckle 21113 can be conveniently inserted into the mounting groove 11, and the situation that the protruding clamping block and the edge of the notch are blocked mutually and cannot be inserted into the mounting groove 11 is avoided.

Example six

Referring to fig. 1 to 10, the present embodiment provides a conductive structure 100, which further has the following design based on the first embodiment:

referring to fig. 2, a plurality of heat dissipation holes 14 are provided on the housing 1 at positions corresponding to the terminal groups 2112.

After the terminal is connected, the heat generated by the terminal is different according to the different current. For terminals with larger current, the heat generated by the terminals is larger, and the heat needs to be dissipated in time. Therefore, in the present embodiment, the heat dissipation holes 14 are provided at positions corresponding to the terminal groups 2112, and heat dissipation is performed.

Specifically, the terminal group 2112 is a power supply terminal group 2112, which is 6P, and the current passing when it is turned on is large, and heat dissipation is required, and therefore, the heat dissipation holes 14 are provided correspondingly to perform heat dissipation. While the other terminal groups 2112 of 14P and 28P are mainly used for transmitting signals, the current passing through is small when being switched on, and heat dissipation is not needed, so the terminal groups 2112 of 14P and 28P are not provided with heat dissipation holes 14.
