CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of the filing date under 35 U.S.C. § 119 (a)-(d) of Chinese Patent Application No. 202320628364.9, filed on Mar. 27, 2023.
FIELD OF INVENTION
The present disclosure generally relates to electrical connectors, and in particular, to an electrical connector housing and an electrical connector.
BACKGROUND
In the application scenarios of existing electrical connectors for flexible printed circuit boards, connection terminals are pre-installed on the flexible printed circuit board to achieve physical and electrical connections between electrical contacts on the flexible printed circuit board and the connection terminals, and to form an assembly of the flexible printed circuit board and the connection terminals. Then, the assembly of the flexible printed circuit board and the connection terminals is inserted into a pocket of a housing of the electrical connector as a whole to form a complete electrical connector for the flexible printed circuit board.
In practice, because the physical and electrical connections between the electrical contacts on the flexible printed circuit board and the connection terminals are achieved by crimping, due to the large number of the connection terminals and the influence of the crimped position, during the process of inserting the assembly of the flexible printed circuit board and the connection terminals into the pocket of the electrical connector housing, the accumulated friction force between elastic sheets of the connection terminals themselves and the pocket of the housing made of plastic is large. A certain strength of insertion force is usually required to fully insert the assembly into the pocket of the electrical connector housing. Moreover, the flexible characteristics of the circuit board also make it difficult for the assembly to be inserted into the pocket of the electrical connector housing, further increasing the difficulty of insertion. In addition, the insertion method of the assembly can easily cause damage to copper foils of crimping portions of the connection terminals, which are not visible after insertion and there is serious quality risk.
Moreover, in the related art, the electrical connector housing has poor tolerance for an adhesive dispensed in the puncturing and crimping region of the flexible circuit board, and has strict specification requirements for the thickness of adhesive dispensing. Once this dispensing thickness exceeds the specification requirements, the flexible circuit board will be difficult to insert. In addition, in the related art, there is still a problem of inaccurate alignment between the connection terminals and through holes of the housing when the assembly of the flexible printed circuit board and the connection terminals is inserted into the pocket of the electrical connector housing.
SUMMARY
An electrical connector housing includes a terminal receiving housing part and a cover part independent of the terminal receiving housing part. The terminal receiving housing part defines a receiving slot receiving a plurality of connection terminals and a circuit board. The terminal receiving housing part and the cover part are capable of being assembled together.

Further, as shown in FIG. 2, the cover part 110, 120 is provided with a first engagement portion 111, 121, and the terminal receiving housing part 130 is provided with a second engagement portion 131. The first engagement portion 111, 121 and the second engagement portion 131 are configured to be capable of being engaged with each other when the cover part 110, 120 and the terminal receiving housing part 130 are assembled together, so that the receiving slot 101 is kept closed (as shown in FIG. 1). The “close” described herein may refer to the restoration of the electrical connector housing 100, along with the receiving slot 101 therein, to the same conventional state as the integrated housing and pocket thereof in the related art.
According to the embodiments of the present disclosure, the electrical connector housing 100 adopts a split design in which the terminal receiving housing part 130 and the cover part 110, 120 are independent of each other to expose the receiving slot 101, for example, as shown in FIG. 2, when the terminal receiving housing part 130 and the cover part 110, 120 are not assembled together. An assembly of the connection terminals 200 and the circuit board 300 (the “assembly” described herein may refer to an integral part formed after the connection terminals 200 and the circuit board 300 are previously connected together by soldering, etc.) can be easily placed into the receiving slot 101, that is, it is convenient to place the connection terminals 200 or the circuit board 300, or the connection terminals 200 and the flexible circuit board 300 can be assembled into the receiving slot 101 of the electrical connector housing 100 with application of only a small external force or even no external force, fundamentally overcoming various defects caused by the insertion method of the assembly adopted in the related art.
In the exemplary embodiment shown in FIGS. 1 and 2, the first engagement portion 111, 121 and the second engagement portion 131 are engaged in a snap-fit manner, wherein one (in the exemplary embodiment shown, the first engagement portion 111, 121) of the first engagement portion 111, 121 and the second engagement portion 131 is an elastic sheet with a protruding block, and the other (in the illustrated exemplary embodiment, the second engagement portion 131) of the first engagement portion 111, 121 and the second engagement portion 131 is an opening being capable of accommodating the protruding block. In other embodiments of the present disclosure, the first engagement portion 111, 121 and the second engagement portion 131 are engaged in any other suitable manner of fastening fit (for example, one of the first engagement portion 111, 121 and the second engagement portion 131 is an insert, and the other of the first engagement portion 111, 121 and the second engagement portion 131 has a hole being capable of accommodating the insert), as long as the receiving slot 101 can be kept closed when the terminal receiving housing part 130 and the cover part 110, 120 are assembled together.

In an embodiment, the cover part 110, 120 is correspondingly provided with one or more first engagement portion 111, 121 on both sides of the receiving slot 101, respectively, and the terminal receiving housing part 130 is correspondingly provided with one or more second engagement portion 131 on both sides of the receiving slot 101, respectively. For example, as shown in FIG. 2, the cover part 120 is correspondingly provided with two first engagement portion 121 on each of both sides of the receiving slot 101 (i.e. along the second direction Y), respectively, and the terminal receiving housing part 130 is correspondingly provided with two second engagement portion 131 on each of both sides of the receiving slot 101 (i.e. along the second direction Y), respectively. With this configuration, it is beneficial to firmly keep the receiving slot 101 closed when the terminal receiving housing part 130 and the cover part 110, 120 are assembled together.
According to the exemplary embodiments of the present disclosure, as shown in FIGS. 1 and 2, the first engagement portion 111, 121 is integrally formed with the cover part 110, 120 and the second engagement portion 131 is integrally formed with the terminal receiving housing part 130. For example, in an embodiment, the first engagement portion 111 and the cover part 110 can be integrally formed from plastic material, the first engagement portion 121 and the cover part 120 can be integrally formed from plastic material, and the second engagement portion 131 and the terminal receiving housing part 130 can also be integrally formed from plastic material.
According to the present disclosure, the cover part 110, 120 is formed with a locking block 113, 123 extending into the receiving slot 101, the locking block 113, 123 being configured to abut against the connection terminal 200 placed into the receiving slot 101.
