タハウジング９４とはそれぞれ絶縁性を有している。2. Description of the Related Art FIG. 10 shows an example of a conventional molded connector (see JP-A-8-250193). This molded connector 90 is made of a synthetic resin core 92 in which terminals 91 are insert-molded, a flexible sealing agent 93 that fills the recesses of the core 92 and adheres to the periphery of the terminals 91, and a synthetic resin that covers the outside of the core 92. Resin connector housing 94
It is composed of The core 92, the sealant 93, and the connector housing 94 have insulating properties.

の浸入が防止される。The terminals 91 are arranged opposite to each other in two stages, and the connector fitting portions 95 and 96 on both sides of the connector housing 94 are provided.
Both ends of the terminal 91 protrude inside. For example, a connector section (not shown) of a device or the like is connected to one connector fitting section 96, and a connector (not shown) on the wire harness side is fitted to the other connector fitting section 95. Since the terminal 91 penetrates through the sealant 93, intrusion of water or the like from one connector fitting portion 96 to the other connector fitting portion 95 is prevented.

る。In a method of manufacturing the molded connector 90, first, a plurality of terminals 91 are insert-molded integrally with a core 92 to obtain a primary molded body 97. The core 92 insulates the terminals and positions the terminals. Then
The concave portion of the core 92 of the primary molded body 97 is filled with a sealing agent 93. Then, the primary molded body 97 is set in a mold (not shown), and a resin material is injected from above the primary molded body 97 to form the connector housing 94, and the molded connector 90 is obtained.

ある。[0005] The primary molding is performed to prevent the terminals 91 from being displaced by the pressure of the resin and causing the terminals 91 to be short-circuited with each other. Further, since the terminals 91 are waterproofed, the terminals 91 are exposed. That's because you can't leave it.

た。However, in the above-described conventional molded connector and the method of manufacturing the same, the terminal 91 is required to be connected with the recent increase in the number of wire harness circuits and the number of circuits in the equipment. When the number of poles is increased, there is a problem that the molded connector 90 becomes large. The increase in the size of the molded connector 90 is contrary to the reduction in the space for arranging the connectors in, for example, an automobile, and thus it is necessary to reduce the size of the multi-pole molded connector. In addition, when the terminals 91 are multi-polarized, if the positioning and fixing of the terminals 91 are not properly performed during the primary molding, there is a risk that the terminals 91 may come into contact with each other and short-circuit, and the pitch of the terminals 91 is not particularly narrowed. In order to increase the size of the molded connector 90, the positioning and fixing of the terminal 91 must be performed accurately. However, the operation is very difficult, and many steps and costs are required for the primary molding. In particular, terminal 91
In order to achieve the multi-polarization and the compactness of the molded connector 90, it is necessary to arrange the terminals 91 not in one stage but in at least two stages or four stages in the primary molding. There has been a demand for the development of technology for positioning and forming and fixing in multiple stages.

Since the bus bars 4 and 5 (FIG. 3A) are locked by the locking claws 30 (31 not shown) facing the terminal 5, there arises a problem that the terminal holder 3 'is enlarged back and forth. If the number of the locking claws 30 and 31 is reduced to avoid this, the locking force of the bus bars 4 and 5 is reduced, and the bus bars 4 and 5 are displaced by the pressure of the resin material during the primary molding described later. Cause danger. By arranging the upper and lower bus bars 4 and 5 in a staggered manner, these problems are solved, and the structure can be made compact and the bus bars 4 and 5 can be reliably positioned and fixed. When the bus bars 4 and 5 are arranged not in the upper and lower stages but in one stage, it goes without saying that the structure is enlarged in the lateral direction.

圧力でのバスバーの位置ずれが確実に防止される。As described above, according to the first and seventh aspects of the present invention, by fixing the bus bar to the terminal holder, displacement of the bus bar due to resin pressure during resin molding is prevented.
The pitch of the terminals can be narrowed, and the compact multi-pole molded connector can be realized. In addition, by arranging the bus bars in a staggered manner, the interval between the upper, lower, left, and right bus bars can be increased irrespective of the narrow pitch, and the insulating property is improved. Further, according to the second aspect of the present invention, the bus bar is engaged with the guide groove to accurately position the bus bar, and the positional accuracy of the terminal at a narrow pitch is improved. Further, according to the third aspect of the present invention, the bus bar is locked by the locking claw and is securely fixed. Therefore, the displacement of the terminal in the first aspect is reliably prevented, and the bus bar fixing operation is performed. Facilitated,
Workability is improved and manufacturing costs are reduced. Further, when the through-holes (mold release holes) for forming the locking claws are opened in the terminal holder, the front and back bus bars are arranged in a zigzag in claim 1, so that the degree of freedom of the position of the through-holes is increased. The through-holes can be provided not in the longitudinal direction of the bus bar but in the width direction, whereby the terminal holder in the longitudinal direction of the bus bar can be made compact, and the multi-pole molded connector can be made compact. According to the fourth and eighth aspects of the invention, by arranging the contact portions of the front and back bus bars in parallel, the contact portions can be exposed at the time of resin molding, and the contact portions can be formed at a narrow pitch. According to the fifth and ninth aspects of the present invention, the multi-pole connector can be easily configured with twice as many terminals as the terminal holder. Claims 6 and 10
According to the described invention, by fixing the terminal holder with the core, the bus bar is more firmly fixed, and the displacement of the bus bar due to the strong pressure during the secondary molding is reliably prevented.
